The Report’s feature article traces the evolution and public policy implications of Phillips curve analysis. The Report also includes highlights of the year, a summary of operations, comparative financial statements, and current lists of directors and officers of our Baltimore, Charleston, Charlotte, Columbia, Culpeper, and Richmond Offices. On behalf of our directors and staff, we wish to thank you for the cooperation and support you have extended to us throughout the past year. Sincerely yours, President The Evolution and Policy Implications of Phillips Curve Analysis Thomas M. Humphrey At the core of modern macroeco nomics is some version or another of the famous Phillips curve relation ship between inflation and unem ployment. The Phillips curve, both in its original and more recently re formulated expectations-augmented versions, has two main uses. In theoretical models of inflation, it provides the so-called “ missing equation” that explains how changes in nominal income divide themselves into price and quantity components. On the policy front, it specifies conditions contributing to the effec tiveness (or lack thereof) of expan sionary and disinflationary policies. For example, in its expectationsaugmented form, it predicts that the power of expansionary measures to stimulate real activity depends crit ically upon how price anticipations are formed. Similarly, it predicts that disinflationary policy will either work slowly (and painfully) or swiftly (and painlessly) depending upon the speed of adjustment of price expectations. In fact, few macro policy questions are discussed without at least some reference to an analytical framework that might be described in terms of some version of the Phillips curve. As might be expected from such a widely used tool, Phillips curve analysis has hardly stood still since its beginnings in 1958. Rather it has evolved under the pressure of events and the progress of economic theo rizing, incorporating at each stage such new elements as the natural rate hypothesis, the adaptive expec tations mechanism, and most re cently, the rational expectations hy pothesis. Each new element ex panded its explanatory power. Each radically altered its policy implica tions. As a result, whereas the Phillips curve was once seen as offering a stable enduring trade-off for the policymakers to exploit, it is now widely viewed as offering no trade-off at all. In short, the orig inal Phillips curve notion of the po tency of activist fine-tuning has given way to the revised Phillips curve notion of policy ineffective ness. The purpose of this article is to trace the sequence of steps that led to this change. Accordingly, the para graphs below sketch the evolution 4 of Phillips curve analysis, empha sizing in particular the theoretical innovations incorporated into that analysis at each stage and the policy implications of each innovation. I. EARLY VERSIONS OF THE PHILLIPS CURVE The idea of an inflationunemployment trade-off is hardly new. It was a key component of the monetary doctrines of David Hume (1752) and Henry Thornton (1802). It was identified statisti cally by Irving Fisher in 1926, although he viewed causation as running from inflation to unemploy ment rather than vice versa. It was stated in the form of an econometric equation by Jan Tinbergen in 1933 and again by Lawrence Klein and Arthur Goldberger in 1955. Finally, it was graphed on a scatterplot chart by A. J. Brown in 1955 and pre sented in the form of a diagrammatic curve by Paul Sultan in 1957. De spite these early efforts, however, it was not until 1958 that modern Phillips curve analysis can be said to have begun. That year saw the publication of Professor A. W. Phillips’ famous article in which he fitted a statistical equation w = f ( U ) to annual data on percentage rates of change of money wages (w ) and the unemployment rate (U ) in the United Kingdom for the period 1861-1913. The result, shown in a chart like Figure 1 with wage infla tion measured vertically and unem ployment horizontally, was a smooth, downward-sloping convex curve that cut the horizontal axis at a positive level of unemployment. The curve itself was given a straightforward interpretation: it showed the response of wages to the excess demand for labor as proxied by the inverse of the unemployment rate. Low unemployment spelled high excess demand and thus up ward pressure on wages. The greater this excess demand the faster the rise in wages. Similarly, high unemployment spelled negative ex cess demand (i.e., excess supply) that put deflationary pressure on wages. Since the rate of change of wages varied directly with excess demand, which in turn varied in versely with unemployment, wage inflation won Id nse with riccrcssing unemployment and fall with increas ing unemployment as indicated by the negative slope of the curve. Moreover, owing to unavoidable frictions in the operation of the labor market, it followed that some fric tional unemployment would exist even when the market was in equi librium, that is, when excess labor demand was zero and wages were stable. Accordingly, this frictional unemployment was indicated by the point at which the Phillips curve crosses the horizontal axis. A c cording to Phillips, this is also the point to which the economy returns if the authorities cease to maintain disequilibrium in the labor market by pegging the excess demand for labor. Finally, since increases in excess demand would likely run into diminishing marginal returns in re ducing unemployment, it followed that the curve must be convex— this convexity showing that successive uniform decrements in unemploy ment would require progressively larger increments in excess demand (and thus wage inflation rates) to achieve them.

T hus successive u n ifo rm de creases in u n e m p lo y m e n t (h o riz o n ta l gray a rro w s) re q u ire progressively larger increases in excess de m and and hence wage in fla tio n rates (ve rtical blu e a rro w s) as we go fro m p o in t a to b to c to d along th e curve. Once equipped with the foregoing theoretical foundations, the Phillips curve gained swift acceptance among economists and policymakers alike. It is important to understand why this was so. At least three factors probably contributed to the attrac tiveness of the Phillips curve. One was the remarkable temporal sta bility of the relationship, a stability revealed by Phillips’ own finding that the same curve estimated for the pre-World War I period 1861-1913 fitted the United Kingdom data for the post-World War II period 194857 equally well or even better. Such apparent stability in a two-variable relationship over such a long period of time is uncommon in empirical economics and served to excite inter est in the curve. 5 A second factor contributing to the success of the Phillips curve was its ability to accommodate a wide varieW of inflation theories. The Phillips curve itself explained infla tion as resulting from excess demand that bids up wages and prices. It was entirely neutral, however, about the causes of that phenomenon. Now excess demand can of course be gen erated either by shifts in demand or shifts in supply regardless of the causes of those shifts. Thus a demand-pull theorist could argue that excess-demand-induced infla tion stems from excessively expan sionary aggregate demand policies while a cost-push theorist could claim that it emanates from tradeunion monopoly power and real shocks operating on labor supply. The Phillips curve could accommo date both views. Economists of rival schools could accept the Phil lips curve as offering insights into the nature of the inflationary process even while disagreeing on the causes of and appropriate remedies for inflation. Finally, the Phillips curve ap pealed to policymakers because it provided a convincing rationale for their apparent failure to achieve full employment with price stability— twin goals that were thought to be mutually compatible before Phillips’ analysis. When criticized for failing to achieve both goals simultaneously, the authorities could point to the Phillips curve as showing that such an outcome was impossible and that the best one could hope for was either arbitrarily low unemployment or price stability but not both. Note also that the curve, by offering a menu of alternative inflation-unemployment combinations from which the authorities could choose, pro vided a ready-made justification for discretionary intervention and acti vist fine tuning. Policymakers had but to select the best (or least unde sirable) combination on the menu and then use their policy instruments to achieve it. For this reason too the curve must have appealed to some policy authorities, not to men tion the economic advisors who sup plied the cost-benefit analysis under lying their choices. From W age-Change Relation to Price-Change Relation A s noted above, the initial Phillips curve depicted a relation between unem ploym ent and w age inflation. Policym akers, how ever, usually specify inflation targets in terms of rates o f change of prices rather than wages. A ccordin gly, to make the Phillips curve m ore useful to p olicy makers, it was therefore necessary to transform it from a w age-change relationship to a price-change rela tionship. This transform ation was achieved by assuming that prices are set by applying a constant m ark-up to unit labor cost and so m ove in step with wages— or, m ore precisely, m ove at a rate equal to the differ ential between the percentage rates of grow th of wages and productivity (th e latter assumed zero h e re ). T he result o f this transform ation was the price-change Phillips relation Figure 2 TRADE-OFFS AND ATTAINABLE COMBINATIONS p Price In flation Rate (%) The position or location o f the Phillips curve defines the fro n tie r or set of attainable inflation-unem ploym ent com bi nations. Using m onetary and fiscal policies, the authorities can attain all com binations lying upon the fro n tie r itself but none in the shaded region below it. In this way the curve acts as a constraint on demandmanagement policy choices. The slope o f the curve shows the trade-offs or rates o f exchange between the tw o evils o f in flatio n and unem ploym ent. (1 ) p ^ a x (U ) w here p is the rate of price inflation, x ( U ) is overall excess demand in labor and hence product markets— this excess demand being an inverse function o f the unem ploym ent rate— and a is a price-reaction coefficient expressing the response of inflation to excess demand. F rom this equa tion the authorities could determine h ow much unem ploym ent w ould be associated with any given target rate of inflation. T h ey could also use it to measure the effect of policies undertaken to obtain a m ore fa v o r able Phillips curve, i.e., policies aimed at low ering the price-response coefficient and the amount of unem ploym ent associated with any given level of excess demand. Trade-Offs and Attainable Combinations T h e foregoin g equation specifies the position (o r distance from o ri g in ) and slope of the Phillips curve — tw o features stressed in policy discussions o f the early 1960s. A s seen by the policym akers of that era, the cu rve’s position fixes the inner boundary, or frontier, o f feasible (attainable) com binations o f infla tion and unem ploym ent rates (see 6 F igure 2 ) . Determ ined by the struc ture of labor and product markets, the position o f the curve defines the set o f all coordinates o f inflation and unem ployment rates the authorities could achieve via implementation of m onetary and fiscal policies. U sing these m acroecon om ic demandmanagement policies the authorities could put the econ om y anywhere on the curve. T h ey could not, however, operate to the left o f it. T h e Phillips curve was view ed as a constraint preventing them from achieving still low er levels of both inflation and un employment. Given the structure of labor and product markets, it would be im possible fo r m onetary and fiscal policy alone to reach inflationunem ploym ent com binations in the region to the left of the curve. T h e slope o f the curve was inter preted as show ing the relevant policy trade-offs (rates o f exchange be tween policy goa ls) available to the authorities. A s explained in early Phillips curve analysis, these trade offs arise because o f the existence of irreconcilable conflicts am ong policy objectives. W h e n the goals of full em ploym ent and price stability are not sim ultaneously achievable, then attempts to m ove the econom y closer to one will necessarily m ove it fu r ther away from the other. T h e rate at which one ob jective must be given up to obtain a little bit m ore of the other is measured by the slope of the Phillips curve. F o r exam ple, when the Phillips cu rve is steeply sloped, it means that a small reduction in unem ploym ent w ould be purchased at the cost of a large increase in the rate of inflation. C onversely, in relatively flat portions of the curve, considerably low er unem ploym ent could be obtained fairly cheaply, that is, at the cost o f only slight increases in inflation. K n ow led ge of these trade-offs w ould enable the authori ties to determine the price-stability sacrifice necessary to buy any given reduction in the unem ploym ent rate. The Best Selection on the Phillips Frontier T h e preceding has described the early view o f the Phillips curve as a stable, enduring trad e-off perm itting Figure 3 THE BEST SELECTION ON THE MENU OF CHOICES p Price In flation Rate The bowed-out curves are social d is u tility contours. Each contour shows all the com binations o f in fla tio n and unem ploym ent resulting in a given level o f social cost or harm. The closer to the origin, the lower the social cost. The slopes o f these contours reflect the relative weights th a t society (or the policy a u th o rity ) assigns to the evils o f in fla tio n and unem ploym ent. The best com bination o f in flatio n and unem ploy m ent th a t the policym akers can reach, given the Phillips curve constraint, is the m ix appearing on the low est attainable social d is u tility contour. Here the additional social benefit from a u n it reduction in unem ploym ent w ill just be w orth the extra in flatio n cost o f doing so. the authorities to obtain permanently low er rates of unem ploym ent in e x change fo r permanently higher rates o f in fla t io n o r v ic e versa. Put differ ently, the curve was interpreted as ottering a menu of alternative m llation-unem ploym ent combinations from which the authorities could choose. Given the menu, the au thorities’ task was to select the p ar ticular inflation-unem ploym ent m ix resulting in the smallest social cost (see F igure 3 ) . T o do this, they w ould have to assign relative weights to the twin evils in a ccord ance with their view s of the co m parative harm caused by each. Then, using m on eta ry/fisca l policy, they would m ove along the Phillips curve, trading off unem ploym ent for infla tion (o r vice versa ) until they reached the point at w hich the addi tional benefit from a further redu c tion in unem ploym ent was just w orth the extra inflation cost of doin g so. H ere w ould be the opti mum, or least undesirable, m ix of inflation and unem ploym ent. A t this point the econ om y w ould be on its low est attainable social disutility contour (th e bow ed -ou t curves radi ating outw ard from the origin of F igu re 3 ) allow ed by the Phillips curve constraint. H ere the unemploym ent-inflation com bination chosen w ould be the one that m ini mized social harm. It was of course understood that if this outcom e in volved a positive rate o f inflation, continuous excess m oney grow th w ould be required to maintain it. F or without such m onetary stimulus, excess demand w ould disappear and the econ om y w ou ld return to the point at w hich the Phillips curve crosses the horizontal axis. Different Preferences, Different Outcomes It was also recognized that p olicy makers might differ in their assess ment of the com parative social cost o f inflation vs. unem ploym ent and thus assign different policy weights to each. P olicym akers w ho believed that unem ploym ent was m ore unde sirable than rising prices w ould as sign a much higher relative weight to the form er than w ould p o licy makers w ho ju d g ed inflation to be 7 the w orse evil. H ence, those with a marked aversion to unem ployment w ould prefer a point higher up on the Phillips curve than w o u ld those m ore anxious to avoid inflation, as shown in F igu re 4. W hereas one political administration might opt for a high pressure econom y on the grounds that the social benefits of low unem ploym ent exceeded the harm done by the inflation necessary to achieve it, another administration might deliberately aim for a low pressure econom y because it believed that som e econom ic slack was a rela tively painless means o f eradicating harmful inflation. Both groups w ould o f course prefer com binations to the southwest of the Phillips c o n straint, dow n closer to the figu re’s origin (th e ideal point of zero infla tion and zero unem ploym ent). A s pointed out before, however, this w ould be im possible given the struc ture o f the econom y which deter mines the position or location o f the Phillips frontier. In short, the p oli cym akers w ould be constrained to com binations lying on this boundary, unless they w ere prepared to alter the econ om y ’s structure. Pessimistic Phillips Curve and the “ Cruel Dilemma” In the early 1960s, there was much discussion of the so-called “ cruel-dilem m a” problem im posed by an unfavorable Phillips curve. T h e cruel dilemma refers to certain pessim istic situations where none of the available combinations on the menu o f policy choices is acceptable to the m ajority o f a country’s voters (see F igu re 5 ) . F or example, sup pose there is som e m axim um rate of inflation, A , that voters are just w illing to tolerate without rem oving the party in pow er. Likewise, sup pose there is som e maxim um toler able rate of unem ployment, B. A s shown in Figure 5, these limits d e fine the zone of acceptable or politi cally feasible com binations of infla tion and unem ployment. A Phillips curve that occupies a position any w here within this zone will satisfy society’s demands for reasonable price stability and high em ploym ent. But if both limits are exceeded and the cu rve lies outside the region of satisfactory outcom es, the system ’ s perform ance w ill fall short o f what was expected of it, and the resulting discontent may severely aggravate political and social tensions. If, as some analysts alleged, the Phillips curve tended to be located so far to the right in the chart that no portion of it fell within the zone of acceptable com binations, then the policym akers w ould indeed be co n fronted with a painful dilemma. A t best they could hold only one of the variables, inflation or unem ploy ment, dow n to acceptable levels. But they could not hold both simultan eously within the limits o f toleration. Faced with such a pessim istic P h il lips curve, policym akers armed only with traditional dem and m anage ment policies w ould find it im pos sible to achieve com binations o f in flation and unem ploym ent acceptable to society. Policies to Shift the Phillips Curve It was this concern and frustration over the seeming inability of m on e tary/fiscal policy to resolve the unem ploym ent-inflation dilemma that induced some econom ists in the early 1960s to urge the adoption o f in com es (w a g e -p rice ) and structural (labor-m arket) policies. M o n e ta r y / fiscal policies alone were thought to be insufficient to resolve the cruel dilemma since the m ost these p oli cies could do was to occu py alterna tive positions on the pessim istic Phillips curve. T hat is, m onetaryfiscal policies could m ove the econ o m y along the given curve, but they could not m ove the curve itself into the zone of tolerable outcom es. W h at was needed, it was argued, w ere new policies that w ould twist or shift the Phillips frontier tow ard the origin of the diagram. O f these measures, incom es p oli cies w ould be directed at the priceresponse coefficient linking inflation to excess demand. Either by d e creeing this coefficient to be zero (as with w age-price fre e z e s), or by re placing it with an officially mandated rate of price increase, or sim ply by persuading sellers to moderate their wage and price demands, such p oli cies w ould low er the rate o f inflation Figure 4 DIFFERENT PREFERENCES, DIFFERENT POLICY CHOICES p Price Inflation Rate Phillips Curve C onstraint In fla tion -U n e m p lo ym en t C hoice of an U nem ploym ent-Averse Adm in istration Social D isu tility C ontours: U nem ploym ent Weighted M ore Heavily In fla tio n Weighted M ore Heavily Figure 5 PESSIMISTIC PHILLIPS CURVE AND THE "CRU EL DILEMMA" i Price Inflation Rate Pessimistic or Unfavorable Phillips Curve; Lies Outside the Zone of Tolerable Outcomes Choice of an Inflation-Averse A d m inistration D ifferent political adm inistrations may d iffe r in their evaluations o f the social harmfulness o f in fla tio n relative to th a t of unem ploym ent.

These weights w ill be re flected in the slopes o f the social d is u tility contours (as those contours are interpreted by the policymakers). The relatively fla t contours reflect the views o f those attaching higher relative weight to the evils o f infla tio n ; the steep contours to those assigning higher w eight to unem ploym ent. An unem ployment-averse adm inistration w ill choose a p o in t on the Phillips curve involving more in flatio n and less unem ploym ent than the com bination selected by an inflation-averse adm inistration. 8 Phillips C urve Shifted D o w n by Incomes and/or Structural Policies A B = M axim um Tolerable Rate o f In flation = M axim um Tolerable Rate of U nem ploym ent Given the unfavorable Phillips curve, policy makers are confronted w ith a cruel choice. They can achieve acceptable rates o f in fla tio n (p oint a) or unem ploym ent (point b) but n o t both. The rationale fo r incomes (wage-price) and structural (labor m arket) policies was to s h ift the Phillips curve down into the zone o f tolerable outcomes. associated with any given level of unem ploym ent and thus twist down the Phillips curve. T h e unstated prem ise was that w age-price controls would hold inflation dow n while excess demand was being used to boost employm ent. Should incom es policies p rove un w orkable or prohibitively expensive in terms of their resource misallocation and restriction-of-freedom costs then the authorities could rely solely on m icroeconom ic structural policies to im prove the trade-off. B y en hancing the efficiency and p erform ance of labor and product markets, these latter policies could low er the Phillips curve by reducing the amount of unem ploym ent associated with any given level of excess de mand. T hus the rationale fo r such measures as job-training and re training program s, job-in form ation and job-cou n selin g services, reloca tion subsidies, anti-discrim ination laws and the like was to shift the Phillips frontier dow n so that the econ om y could obtain better inflation-unem ploym ent com binations. II. INTRODUCTION OF SHIFT VARIABLES U p until the m id-1960s the P hil lips curve received widespread and largely uncritical acceptance. F ew questioned the usefulness, let alone the existence, of this construct. In policy discussions as well as e co nom ic textbooks, the Phillips curve was treated as a stable, enduring relationship or menu o f policy choices. B eing stable (an d barring the application of incomes and struc tural p o licie s), the menu never changed. E m pirical studies of the 19001958 U . S. data soon revealed, h ow ever, that the menu for this country was hardly as stable as its original British counterpart and that the Phillips curve had a tendency to shift over time. A ccord in g ly , the trad e-off equation was augmented with additional variables to account for such movements. T h e inclusion of these shift variables m arked the second stage of Phillips curve analy sis and meant that the trade-off equation could be written as (2 ) -»■ * VV11C 1C p — a x ( U ) -j- z <r C, iO Ct -»r ♦» V r\-f U l V»1 A f V U i X U U IV /O productivity, profits, trade union effects, unem ploym ent dispersion and the like— thought capable of shifting the inflation-unem ploym ent trade-off. In retrospect, this vector or list was deficient both for what it in cluded and what it left out. E xclu d ed at this stage w ere variables repre senting inflation expectations— later shown to be a chief cause o f the shifting short-run Phillips curve. O f the variables included, subsequent analysis w ould reveal that at least three— productivity, profits, and measures o f union m on op oly pow er — were redundant because they co n stituted underlying determinants of the demand for and supply o f labor and as such w ere already captured by the excess demand variable, U . T his criticism , how ever, did not apply to the unem ploym ent disper sion variable, changes in w hich w ere independent of excess dem and and w ere indeed capable o f causing shifts in the aggregate Phillips curve. T o explain h ow the dispersion of unem ploym ent across separate m icro labor markets cou ld affect the aggre gate trade-off, analysts in the early 1960s used diagrams similar to F ig ure 6. That figure depicts a repre sentative m icrom arket Phillips curve, the exact replica o f w hich is presum ed to exist in each local labor market and aggregation over which yields the m acro Phillips curve. A cco rd in g to the figure, if a given national unem ploym ent rate U * w ere equally distributed across local labor markets such that the same rate prevailed in each, then wages everywhere w ou ld inflate at the single rate indicated by the point w * on the curve. But if the same a ggre gate unem ploym ent w ere unequally distributed across local markets, then wages in the different markets w ould inflate at different rates. Because of the cu rve’s con vexity (w h ich ren d ers w age inflation m ore responsive to leftward than to rightw ard devi ations from average unem ploym ent along the cu rv e ) the average of these 9 Figure 6 EFFECTS OF UNEMPLOYMENT DISPERSION w Wage In fla tio n Rate If aggregate unem ploym ent at rate U* were evenly distributed across individual labor markets such th a t the same rate prevailed everywhere, then wages would inflate at the rate w* both locally and nationally. But if aggregate unem ploym ent U * is unequally distributed such that rate UA exists in m arket A and U g in m arket B, then wages w ill inflate at rate in the form er m arket and Wg in the latter. The average o f these local in flatio n rates at aggregate unem ploy m ent rate U* is w Q which is higher than in fla tio n rate w* o f the no-dispersion case. C onclusion: The greater the dispersion of unem ploym ent, the higher the aggregate in fla tio n rate associated w ith any given level of aggregate unem ploym ent. Unem ploym ent dispersion shifts the aggregate Phillips curve rightward. wage inflation rates w ould exceed the rate of the no-dispersion case. In short, the diagram suggested that, for any given aggregate unem ploy ment rate, the rate o f aggregate wage inflation varies directly with the dispersion o f unemployment across microm arkets, thus displacing the macro Phillips curve to the right. F rom this analysis, econom ists in the early 1960s concluded that the greater the dispersion, the greater the outward shift of the aggregate Phillips curve. T o prevent such shifts, the authorities w ere advised to apply structural policies to m ini mize the dispersion of unem ploy ment across industries, regions, and occupations. A lso, they were advised to minimize unem ploym ent’s disper sion over time since, with a con vex Phillips curve, the average inflation rate w ould be higher the m ore un em ploym ent is allowed to fluctuate around its average (m ea n ) rate. A Serious Misspecification T he preceding has shown how shift variables were first in corp o rated into the Phillips curve in the early to m id-1960s. N otably absent at this stage were variables repre senting price expectations. T o be sure, the past rate o f price change was sometimes used as a shift vari able to represent catch-up or cost-ofliving adjustm ent factors in wage and price demands. Rarely, however, was it interpreted as a p ro x y for anticipated inflation. N ot until the late 1960s w ere expectational vari ables fully incorporated into Phillips curve equations. B y then, o f course, inflationary expectations had becom e too prom inent to ignore and many analysts w ere perceiving them as the dominant cause of observed shifts in the Phillips curve. C oinciding with this perception was the belated recognition that the original Phillips curve involved a misspecification that could only be corrected by the incorporation of a price-expectations variable in the trade-off. T h e original Phillips curve was expressed in terms of nom inal w age changes, w = f ( U ) . Since neoclassical econom ic theory teaches that real rather than nominal wages adjust to clear labor markets, how ever, it follow s that the Phillips curve should have been stated in terms of real wage changes. Better still (sin ce wage bargains are made with an eye to the fu tu re ), it should have been stated in terms o f ex pected real wage changes, i.e., the differential between the rates of change o f nominal w ages and e x pected future prices, w — pe= f ( U ) . In short, the original Phillips curve required a price-expectations term to render it correct. R ecognition of this fact led to the developm ent of the expectations-augm ented Phillips curve described below. III. THE EXPECTATIONS-AUGMENTED PHILLIPS CURVE AND THE ADAPTIVE-EXPECTATIONS MECHANISM T h e original Phillips curve equa tion gave w ay to the expectationsaugmented version in the early 1970s. T hree innovations ushered in this change. T he first was the re specification of the excess demand variable. O riginally defined as an in verse function o f the unem ploym ent rate, x ( U ) , excess demand was redefined as the discrepancy or gap between the natural and actual rates o f unem ployment, U n — U . T he natural (o r full em ploym ent) rate of unem ploym ent itself was defined as the rate that prevails in steady-state equilibrium when expectations are fully realized and incorporated into all wages and prices and inflation is neither accelerating nor decelerating. It is natural in the sense ( 1 ) that it represents normal full-em ploym ent equilibrium in the labor and hence com m odity markets, ( 2 ) that it is independent o f the steady-state infla tion rate, and ( 3 ) that it is deter mined by real structural forces (m arket frictions and im perfections, jo b inform ation and labor mobility costs, tax laws, unem ploym ent sub sidies, and the like) and as such is not susceptible to manipulation by aggregate demand policies. T h e second innovation was the introduction of price anticipations into Phillips curve analysis result ing in the expectations-augm ented equation 10 (3 ) p = a ( U N- U ) + p e where excess demand is n ow written as the gap between the natural and actual unem ployment rates and pe is the price expectations variable repre senting the anticipated rate of infla tion. T his expectations variable entered the equation with a coeffi cient of unity, reflecting the assump tion that price expectations are com pletely incorporated in actual price changes. T h e unit expectations c o efficient implies the absence of m oney illusion, i.e., it implies that people are concerned with the e x pected real purchasing p ow er of the prices they pay and receive (o r , alternatively, that they wish to main tain their prices relative to the prices they expect others to be ch argin g) and so take anticipated inflation into account. A s will be shown later, the unit expectations coefficient also im plies the com plete absence o f a trade o ff between inflation and unem ploy ment in long-run equilibrium when expectations are fully realized. N ote also that the expectations variable is the sole shift variable in the equa tion. A ll other shift variables have been omitted, reflecting the view, prevalent in the early 1970s, that changing price expectations w ere the predominant cause of observed shifts in the Phillips curve. Expectations-Generating Mechanism T h e third innovation was the in corporation o f an expectationsgenerating mechanism into Phillips curve analysis to explain h ow the price expectations variable itself was determined. Generally a simple adaptive expectations or errorlearning mechanism was used. A c cording to this mechanism, expecta tions are adjusted (a d a p ted ) by some fraction of the forecast error that occurs when inflation turns out to be different than expected. In symbols, (4 ) pe = b (p p e) where the dot over the price exp ec tations variable indicates the rate of change (tim e derivative) o f that variable, p — pe is the expectations or forecast error (i.e., the difference be tween actual and expected price in fla tion ), and b is the adjustm ent fraction. A ssum ing, fo r example, an adjustm ent fraction o f /l 2, equa tion 4 says that if the actual and expected rates of inflation are 10 percent and 4 percent, respectively— i.e., the expectational error is 6 percent— then the expected rate of inflation will be revised upward by an amount equal to half the error, or 3 percentage points. Such revision will continue until the expectational error is eliminated. A nalysts also dem onstrated that equation 4 is equivalent to the p rop o sition that expected inflation is a geom etrically declining weighted average of all past rates of inflation with the w eights sum m ing to one. T his unit sum of weights ensures that any constant rate o f inflation eventually w ill be fully anticipated, as can be seen by w riting the errorlearning mechanism as (5 ) pe = S v ip -i where 2 indicates the operation of summing the past rates o f inflation, the subscript i denotes past time periods, and Vi denotes the weights attached to past rates o f inflation. W ith a stable inflation rate p un changing over time and a unit sum of weights, the equation’s right-hand side becom es simply p, indicating that when expectations are form u lated adaptively via the errorlearning scheme, any constant rate of inflation w ill indeed eventually be fully anticipated. Both versions of the adaptive expectations mechanism (i.e., equations 4 and 5) were com bined with the expectationsaugmented Phillips equation to e x plain the mutual interaction of actual inflation, expected inflation, and e x cess demand. The Natural Rate Hypothesis T hese three innovations— the re defined excess demand variable, the expectations augmented Phillips curve, and the error-learning mecha nism— form ed the basis o f the cele brated natural rate and acceleration ist hypotheses that radically altered econom ists’ and policym akers’ views of the Phillips curve in the late 1960s and early 1970s. A cco rd in g to the natural rate hypothesis, there exists no permanent trade-off be tween unem ploym ent and inflation since real econ om ic variables tend to be independent of nominal ones in steady-state equilibrium. T o be sure, trade-offs may exist in the short run. F o r exam ple, surprise inflation, if unperceived by wage earners, may, by raising product prices relative to nominal wages and thus low erin g real wages, stimulate em ploym ent tem porarily. But such trade-offs are inherently transitory phenom ena that stem from unex pected inflation and that vanish once expectations (an d the wages and prices em bodying them ) fully adjust to inflationary experience. In the long run, when inflationary surprises disappear and expectations are real ized such that wages reestablish their preexisting levels relative to product prices, unem ploym ent returns to its natural (equ ilibriu m ) rate. This rate is com patible with all fully anticipated steady-state rates o f in flation, im plying that the long-run Phillips cu rve is a vertical line at the natural rate o f unem ployment. E quation 3 em bodies these con clu sions. T hat equation, when rear ranged to read p — p e= a ( U N— U ) , states that the trade-off is between unexpected inflation (th e difference between actual and expected infla tion, p — pe) and unem ployment. That is, on ly surprise price increases could induce deviations of unem ploy ment from its natural rate. The equation also says that the trade-off disappears when inflation is fully anticipated (i.e., when p — pe equals z e r o ), a result guaranteed for any steady rate o f inflation by the errorlearning m echanism ’s unit sum of weights. M oreover, accordin g to the equation, the right-hand side must also be zero at this point, which im plies that unem ploym ent is at its natural rate. T h e natural rate o f unem ploym ent is therefore com pat ible with any constant rate o f infla tion provided it is fully anticipated (w hich it eventually must be by virtue o f the error-learning weights adding to o n e ). In short, equation 3 asserts that inflation-unem ploym ent trade-offs cannot exist when infla tion is fully anticipated. A n d equa11 Figure 7 THE NATURAL RATE HYPOTHESIS AND ADJUSTMENT TO STEADY-STATE EQUILIBRIUM Price In fla tio n Rate Natural Rate of U ne m p lo ym en t The vertical line L through the natural rate of unem ploym ent is the long-run steady state Phillips curve along which all rates of in fla tio n are fu lly anticipated.

Figure 8 THE ACCELERATIONIST HYPOTHESIS p tion 5 ensures that this latter con d i tion must obtain fo r all steady infla tion rates such that the long-run Phillips cu rve is a vertical line at the natural rate o f unem ploym ent.1 T h e message o f the natural rate hypothesis was clear. A higher stable rate o f inflation could not buy a permanent drop in joblessness. M ovem ents to the left along a shortrun Phillips cu rve only provok e expectational w a g e /p rice adjustments that shift the curve to the right and restore unem ploym ent to its natural rate (see F igu re 7 ) . In sum, Phillips curve trade-offs are inherently tran sitory phenom ena. A ttem pts to exploit them w ill only succeed in raising the perm anent rate o f infla tion w ithout accom plishing a lasting reduction in the unem ploym ent rate. Price Inflation Rate The Accelerationist Hypothesis Since the adjustm ent of expected to actual in fla tio n works to restore unem ploym ent to its natural equilibrium level U|yj at any steady rate of in flatio n , the authorities must continually raise (accelerate) the in flatio n rate if they wish to peg unem ploym ent at some a rb itrarily low level such as U^. Such acceleration, by generating a continuous succession o f in fla tio n surprises, perpetually frustrates the fu ll adjustm ent o f expecta tions that w ould return unem ploym ent to its natural rate. Thus attem pts to peg unem ploym ent at w ill provoke explo sive, ever-accelerating inflation. The econom y w ill travel the path AB C D w ith the rate o f in flatio n rising from zero to p-j to P 2 to pg etc. T h e expectations-augm ented P hil lips curve, when com bined with the error-learning process, also yielded the celebrated accelerationist hy pothesis that dom inated many policy discussions in the inflationary 1970s. T his hypothesis, a corollary o f the natural rate concept, states that since there exists no long-run trade off between unem ploym ent and infla tion, attempts to peg the form er variable below its natural (equ ilib riu m ) level must produce everincreasing inflation. Fueled by p ro gressively faster m onetary expan sion, such price acceleration w ould keep actual inflation always running ahead o f expected inflation, thereby perpetuating the inflationary sur prises that prevent unem ployment from returning to its equilibrium level (see F igu re 8 ) . 1 Actually, the long-run Phillips curve may become positively sloped in its upper ranges as higher inflation leads to greater inflation variability (volatil ity, unpredictability) that raises the natural rate of unem ployment. Higher and hence more variable and erratic inflation can raise the equilib rium level of unem U ployment by generat ing increased uncertainty that inhibits business activity and by introducing noise into market price signals, thus reducing the efficiency of the price system as a coordinating and allocating mechanism. 12 A ccelerationists reached these conclusions via the follow in g route. T h ey noted that equation 3 posits that unem ploym ent can differ from its natural level only so long as actual inflation deviates from e x pected inflation. But that same equation together with equation 4 implies that, by the very nature of the error-learning mechanism, such deviations cannot persist unless in flation is continually accelerated so that it always stays ahead of e x pected inflation.2 I f inflation is not accelerated, but instead stays co n stant, then the gap between actual and expected inflation will eventu ally be closed. T h erefore accelera tion is required to keep the gap open if unem ploym ent is to be maintained below its natural equilibrium level. In other w ords, the long-run trade o ff im plied by the accelerationist h y pothesis is betw een, unem ploym ent and the rate of acceleration of the inflation rate, in contrast to the co n ventional trade-off between unem ploym ent and the inflation rate itself as im plied by the original Phillips cu rve.3 Policy Implications of the Natural Rate and Accelerationist Hypotheses A t least tw o policy implications stem med from the natural rate and accelerationist propositions. First, the authorities could either peg un em ploym ent or stabilize the rate of inflation but not both. If they pegged 2 Taking the time derivative of equa tion 3, then assuming that the deviation of U from U N is pegged at a constant level by the authorities such that its rate of change is zero, and then substi tuting equation 4 into the resulting expression yields p = b(p — pe) which says that the inflation rate must accelerate to stay ahead of expected inflation. 3 The proof is simple. Merely substi tute equation 3 into the expression pre sented in the preceding footnote to obtain p = b a (U N— U ) which says that the trade-off is between the rate of acceleration of inflation p and unemployment U relative to its natural rate. unem ploym ent, they w ould lose co n trol of the rate of inflation because the latter accelerates when unem ploym ent is held below its natural level. Alternatively, if they stabilized the inflation rate, they w ould lose control o f unem ploym ent since the latter returns to its natural level at any steady rate of inflation. Thus, contrary to the original Phillips h y pothesis, they could not peg unem ploym ent at a given constant rate of inflation. T hey could, how ever, ch oose the steady-state inflation rate at w hich unem ploym ent returns to its natural level. A second policy im plication stem m ing from the natural rate hypothe sis was that the authorities could ch oose from am ong alternative tran sitional adjustm ent paths to the de sired steady-state rate of inflation. Suppose the authorities wished to m ove from a high inherited inflation rate to a zero or other low target inflation rate. T o do so, they must low er inflationary expectations, a m a jor determinant of the inflation rate. But equations 3 and 4 state that the only way to low er expecta tions is to create slack capacity or excess supply in the econom y. Such slack raises unem ploym ent above its natural level and thereby causes the actual rate of inflation to fall below the expected rate so as to induce a dow n w ard revision o f the latter.4 T h e equations also indicate that how fast inflation com es d ow n depends on the amount of slack created.5 M uch slack means fast adjustm ent and a relatively rapid attainment of the inflation target. C onversely, little slack means sluggish adjustm ent and a relatively slow attainment of the inflation target. T hus the p olicy ch oice is between adjustm ent paths offerin g high excess unem ploym ent 4 The proof is straightforward. Simply substitute equation 3 into equation 4 to obtain pe= b a ( U N— U ).

STATISTICAL TESTS OF THE NATURAL RATE HYPOTHESIS /T ' u „ X iiC 6 Controls advocates proposed a third policy choice: use ws-gc-pricc controls to hold actual below expected inflation so as to force a swift reduction of the latter. Overlooked was the fact that controls would have little impact on expectations unless the public was con vinced that the trend of prices when controls were in force was a reliable indicator of the future price trend after controls were lifted. Convincing the public would be difficult if controls had failed to stop inflation in the past. Aside from this, it is hard to see why controls should have a stronger impact on expectations than a preannounced, demonstrated policy of disinflationary money growth. — -----------j : ___ 1_____________________ ] p i CCCUlilg iidS CA.dillli.lCCi j.1 - _ L11C third stage o f Phillips curve analysis in which the natural rate hypothesis was form ed.

If the coefficient is one, as in equation 3, then the natural rate hypothesis is valid and no lon g-ru n inflation-unem ploym ent tra d e-off exists for the policym akers to exploit. But if the coefficient is less than one, the natural rate h y pothesis is refuted and a long-run tra d e-off exists. Analysts empha sized this fact by w riting the e x p ec tations augmented equation as Figure 10 (6 ) THE EXPECTATIONS COEFFICIENT AND THE LONG-RUN STEADY-STATE PHILLIPS CURVE p Price In fla tio n Rate p = a ( U N— U)-f</>pe w here is the coefficient (w ith a value of between zero and o n e ) at tached to the price expectations vari able. In long-run equilibrium, of course, expected inflation equals actual inflation, i.e., pe= p . Setting expected inflation equal to actual inflation as required for long-run equilibrium and solving for the ac tual rate o f inflation yields (7) P = ^ ( U n-U ). B esides show ing that the long-run Phillips curve is steeper than its short-run counterpart (since the slope parameter o f the form er, a / ( l — <f>), exceeds that of the latter, a ) , equation 7 shows that a long-run tra d e-off exists only if the expecta tions coefficient </> is less than one. I f the coefficient is one, how ever, the slope term is infinite, which means that there is no relation between in flation and unem ploym ent so that the tra d e-off vanishes (see F igure 10). Statistical tests o f the natural rate hypo thesis sought to determ ine the magnitude o f the expectations coefficient 0 in the long-run steady-state Phillips curve equation p - tV un - u )- A coefficient o f one means th a t no perma nent trade-off exists and the steady-state Phillips curve is a vertical line through the natural rate o f unem ploym ent. Conversely, a coefficient o f less than one signifies the existence o f a long-run Phillips curve trade o ff w ith negative slope fo r the policym akers to exploit. N ote th a t the long-run curves are steeper than the short-run ones, indi cating that permanent trade-offs are less favorable than tem porary ones. M an y o f the empirical tests esti mated the coefficient to be less than unity and concluded that the natural rate hypothesis was invalid. But this con clu sion was sharply challenged by econom ists w ho contended that the tests contained statistical bias that tended to w ork against the natu ral rate hypothesis. T hese critics pointed out that the tests typically used adaptive-expectations schemes as em pirical proxies for the unob servable price expectations variable. T h e y further showed that if these p rox ies w ere inappropriate measures o f inflation expectations then esti mates o f the expectations coefficient 14 could well be biased dow nw ard. If so, then estimated coefficients o f less than one constituted no d isp roof of the natural rate hypothesis. Rather they constituted evidence o f inade quate measures o f expectations. Shortcomings of the AdaptiveExpectations Assumption In connection with the foregoing, the critics argued that the adaptiveexpectations scheme is a grossly in accurate representation of how people form ulate price expectations. T h ey pointed out that it postulates naive expectational behavior, h old ing as it does that people form an ticipations solely from a weighted average o f past price experience with weights that are fix ed and indepen dent o f econom ic conditions and policy actions. It im plies that people look only at past price changes and ignore all other pertinent in form a tion— e.g., m oney grow th rate changes, exchange rate m ovem ents, announced policy intentions and the like— that could be used to reduce expectational errors. T hat people w ould fail to exploit inform ation that w ould im prove expectational accu racy seems implausible, how ever. In short, the critics contended that adaptive expectations are not w holly rational if other inform ation besides past price changes can im prove in flation predictions. M any econom ists have since pointed out that it is hard to accept the notion that individuals w ould continually form price anticipations from any scheme that is inconsistent with the way inflation is actually generated in the econom y. B eing different from the true inflationgenerating mechanism, such schemes w ill produce expectations that are systematically w ron g. If so, rational forecasters w ill cease to use them. F or exam ple, suppose inflation w ere actually accelerating or decelerating. A cco rd in g to equation 5, the adap tive expectations m odel w ould sys tematically underestimate the infla tion rate in the form er case and overestimate it in the latter. U sin g a unit weighted average o f past infla tion rates to forecast a steadily rising or falling rate w ould yield a suc cession o f on e-w ay errors. The discrepancy between actual and e x pected inflation w ould persist in a perfectly predictable way such that forecasters w ould be provided free the inform ation needed to correct their mistakes. P erceiving these p er sistent expectational mistakes, ra tional individuals w ould quickly abandon the error-learning model for m ore accurate expectationsgenerating schemes. O n ce again, the adaptive-expectations mechanism is im plausible because of its incom pati bility with rational behavior. V. FROM ADAPTIVE EXPECTATIONS TO RATIONAL EXPECTATIONS T h e shortcom ings of the adaptive expectations approach to the m odel ing of expectations led to the in cor poration of the alternative rational expectations approach into Phillips curve analysis. A ccord in g to the ra tional expectations hypothesis, indi viduals will tend to exploit all avail able pertinent inform ation about the inflationary process when making their price forecasts. If true, this means that forecasting errors ulti mately could arise only from random (u n foreseen ) shocks occurring to the econom y. A t first, o f course, price forecasting errors might also arise because individuals initially possess limited or incom plete in for mation about, say, a new policy re gim e, econom ic structure, or infla tion generating mechanism. But it is unlikely that this latter condition w ould persist. F or if the public were truly rational, it w ould quickly learn from these inflationary surprises or prediction errors (data on which it acquires costlessly as a side condition of buying g o o d s) and incorporate the free new inform ation into its forecasting procedures, i.e., the source of forecasting mistakes w ould be sw iftly perceived and systemati cally eradicated. A s know ledge of p olicy and the inflationary process im proved, forecasting models w ould be continually revised to produce m ore accurate predictions. S oon all systematic (p red ictable) elements influencing the rate o f inflation w ould becom e know n and fully understood, and individuals’ price expectations w ould constitute the m ost accurate (unbiased) forecast consistent with that know ledge.7 W h en this happened the econom y w ould con verge to its rational e x pectations equilibrium and people’s price expectations w ould be the same as those implied by the actual infla tion generating mechanism. A s in corporated in natural rate Phillips curve models, the rational expecta tions hypothesis implies that there after, except fo r unavoidable sur prises due to purely random shocks, price expectations w ould always be correct and the econom y w ould al ways be at its long-run steady-state equilibrium. Policy Implications of Rational Expectations T h e strict (flexible price, instan taneous market clearing) rationalexpectations approach has radical p olicy implications. W h en in corp o rated into natural rate Phillips curve equations, it implies that systematic policies— i.e., those based on feed back control rules defining the au thorities’ response to changes in the econ om y— cannot influence real variables such as unemployment even in the short run, since people w ould have already anticipated what the policies are goin g to be and acted upon those anticipations. T o have an impact on output and em ploy ment, the authorities must be able to create a divergence between actual and expected inflation. T his follow s from the proposition that inflation influences real variables only when it is unanticipated. T o low er un em ploym ent in the Phillips curve equation p — pe = a ( U N— U ) , the authorities must be able to alter the actual rate o f inflation without simultaneously causing an identical change in the expected future rate. T his may be impossible if the public can predict policy actions. P olicy actions, to the extent they are systematic, are predictable. Sys 7 Put differently, rationality implies that current expectational errors are uncorrelated with past errors and with all other known information, such cor relations already having been perceived and exploited in the process of improv ing price forecasts. 15 tematic policies are sim ply feedback rules or response functions relating policy variables to past values of other econ om ic variables. These policy response functions can be esti mated and incorporated into fore casters’ price predictions. In other w ords, rational individuals can use past observations on the behavior of the authorities to discover the p olicy rule. O n ce they know the rule, they can use current observations on the variables to w hich the policym akers respond to predict future policy m oves. Then, on the basis o f these predictions, they can correct for the effect o f anticipated policies before hand by m aking appropriate ad ju st ments to nominal w ages and prices. Consequently, when stabilization ac tions do occur, they will have no im pact on real variables like unem ploy ment since they will have been dis counted and neutralized in advance. In short, rules-based policies, being in the inform ation set used by ra tional forecasters, will be perfectly anticipated and fo r that reason will have no im pact on unem ploym ent. T h e only conceivable w ay that policy can have even a short-run influence on real variables is fo r it to be u n ex pected, i.e., the policym akers must either act in an unpredictable ran dom fashion or secretly change the policy rule. A pa rt from such tactics, which are incom patible with most notions o f the proper conduct of public policy, there is no w ay the authorities can influence real vari ables, i.e., cause them to deviate from their natural equilibrium levels. T h e authorities can, how ever, influence a nominal variable, nam ely the infla tion rate, and should concentrate their efforts on doin g so if som e par ticular rate (e .g ., z e ro ) is desired. A s fo r disinflation strategy, the rational expectations approach gen erally calls fo r a preannounced sharp swift reduction in m oney grow th — p rovided o f course that the g overn m ent’s com m itm ent to ending infla tion is sufficiently credible to be believed. H a v in g chosen a zero target rate of inflation and having con vin ced the public o f their deter m ination to achieve it, the policy au thorities should be able to do so w ithout creating a costly transitional rise in unem ploym ent. F or, given that rational expectations adjust in finitely faster than adaptive exp ec tations to a credible preannounced disinflationary policy, the transition to price stability should be relatively quick and painless. No Exploitable Trade-Offs T o summarize, the rationality hy pothesis, in con ju n ction with the natural rate hypothesis, denies the existence of exploitable Phillips cu rve trade-offs in the short run a? well as the long. In so doing, it differs from the adaptive expecta tions version of natural rate Phillips cu rve models. U n d er adaptive e x pectations, short-run trade-offs exist because expectations do not adjust instantaneously to eliminate forecast errors arising from policy-engineered changes in the inflation rate. W ith expectations adapting to actual in flation with a lag, m onetary policy can generate unexpected inflation and consequently influence real vari ables in the short run. T h is cannot happen under rational expectations w here both actual and expected in flation adjust identically and instan taneously to anticipated policy changes. In short, under rational expectations, system atic policy can not induce the expectational errors that generate short-run Phillips cu rves.8 Phillips curves m ay exist, to be sure. But they are purely ad ventitious phenom ena that are en tirely the result of unpredictable random shocks and cannot be e x ploited by policies based upon rules. In sum, no role remains fo r sys tematic counter-cyclical stabilization p olicy in Phillips curve m odels em b odyin g rational expectations and the natural rate hypothesis. T h e only thing such p olicy can influence in 8 Note that the rational expectations hypothesis also rules out the acceler ationist notion of a stable trade-off between unemployment and the rate of acceleration of the inflation rate. If expectations are formed consistently with the way inflation is actually gen erated, the authorities will not be able to fool people by accelerating inflation or by accelerating the rate of acceler ation, etc. Indeed, no systematic policy will work if expectations are formed consistently with the way inflation is actually generated in the economy. these models is the rate o f inflation which adjusts im mediately to e x pected changes in m oney grow th. Since the models teach that the full effect of ruies-based policies is 011 th e in f la t io n ra te , i t f o llo w s t h a t th e authorities— provided they believe that the models are at all an accurate representation of the way the w orld w orks— should concentrate their efforts on controlling that nominal inflation variable since they cannot systematically influence real vari ables. These propositions are dem on strated with the aid o f the expository model presented in the A pp en d ix. VI. EVALUATION OF RATIONAL EXPECTATIONS T he preceding has shown h ow the rational expectations assumption combines with the natural rate hy pothesis to yield the policyineffectiveness conclusion that no Phillips curves exist fo r policy to exploit even in the short run. Given the importance of the rational exp ec tations com ponent in m odern P hil lips curve analysis, an evaluation of that com ponent is n ow in order. O ne advantage o f the rationalexpectations hypothesis is that it treats expectations form ation as a part of optim izing behaviour. B y so doing, it brings the theory o f price anticipations into accord with the rest of econom ic analysis. T h e latter assumes that people behave as ra tional optimizers in the production and purchase of good s, in the choice of jobs, and in the making of invest ment decisions. F o r consistency, it should assume the same regarding expectational behavior. In this sense, the rationalexpectations theory is superior to rival explanations, all of which im ply that expectations may be consistently w rong. It is the only theory that denies that people make systematic expectation errors. N ote that it does not claim that people possess perfect foresight or that their expectations are always accurate. W h a t it does claim is that they perceive and elim i nate regularities in their forecasting mistakes. In this way they discover the actual inflation generating p ro 16 cess and use it in form in g price e x pectations. A n d with the public’ s rational expectations of inflation being the same as the mean v a lu e of the in f la t io n g e n e r a tin g process, tllO S e e x o e c ta tio n s c a n n o t h e wrnncr T* o on average. A n y errors will be ran dom , not systematic. T he same can not be said fo r other expectations schemes, how ever. N ot being identi cal to the expected value of the true inflation generating process, those schemes will p rodu ce biased expecta tions that are system atically w rong. Biased expectations schemes are difficult to ju stify theoretically. Sys tematic mistakes are harder to e x plain than is rational behavior. T rue, nobody really know s h ow expecta tions are actually form ed. But a theory that says that forecasters do not continually make the same mistakes seems intuitively m ore plausible than theories that im ply the opposite. C onsidering the profits to be made from im proved forecasts, it seems inconceivable that systematic expectational errors w ould persist. S om ebody w ou ld surely notice the errors, correct them, and profit by the corrections. T ogeth er, the profit m otive and com petition w ould re duce forecasting errors to random ness. Criticisms of the Rational Expectations Approach Despite its logic, the rational e x pectations hypothesis still has many critics. Som e still maintain that e x pectations are basically nonrational, i.e., that m ost people are too naive or uninform ed to form ulate unbiased price expectations. O verlooked is the counterargum ent that relatively uninform ed people often delegate the responsibility fo r form ulating ra tional forecasts to inform ed special ists and that professional forecasters, either through their ability to sell superior forecasts or to act in behalf o f those w ithout same, will ensure that the econ om y will behave as if all people were rational. O ne can also note that the rational expecta tions hypothesis is m erely an im plication of the uncontroversial as sum ption o f profit (an d utility) m axim ization and that, in any case, econom ic analysis can hardly p ro ceed without the rationality assum p tion. O ther critics insist, how ever, that expectational rationality cannot hold during the transition to new policy regim es or other structural changes in the econom y since it re quires a long time to understand such changes and learn to adjust to them. A gainst this is the counter argument that such changes and their effects are often foreseeable from the econom ic and political events that precede them and that people can quickly learn to predict regim e changes just as they learn to predict the w orkings o f a given re gim e. T his is especially so when regim e changes have occu rred in the past. H aving experienced such changes, forecasters will be sensitive to their likely future occurrence. M ost of the criticism , how ever, is directed not at the rationality as sum ption per se but rather at an other key assumption underlying its policy-ineffectiveness result, namely the assumption o f no policym aker inform ation or maneuverability ad vantage over the private sector. T his assumption states that private forecasters possess exactly the same inform ation and the ability to act upon it as do the authorities. Critics hold that this assumption is im plaus ible and that if it is violated then the policy ineffectiveness result ceases to hold. In this case, an exploitable short-run Phillips curve reemerges, allow ing some limited scope for sys tematic m onetary policies to reduce unem ployment. F or example, suppose the authori ties possess m ore and better in for mation than the public. H aving this inform ation advantage, they can p re dict and hence respond to events seen as purely random by the public. T hese policy responses will, since they are unforeseen by the public, affect actual but not expected infla tion and thereby change unem ploy ment relative to its natural rate in the (in verted ) Phillips curve equa tion U N— U — (1 / a ) ( p — p e) . Alternatively, suppose that both the authorities and the public possess identical inform ation but that the latter grou p is constrained by lon g term contractual obligations from exploiting that inform ation. F o r e x ample, suppose w orkers and em ploy ers make labor contracts that fix nominal wages fo r a longer period of time than the authorities require to change the m oney stock. W ith nom inal wages fixed and prices respond ing to m oney, the authorities are in a position to low er real wages and thereby stimulate employment with an inflationary monetary policy. In these ways, contractual and in form ational constraints are alleged to create output and employm entstimulating opportunities for system atic stabilization policies. Indeed, critics have tried to demonstrate as much by incorporating such co n straints into rational expectations Phillips curve models similar to the one outlined in the A pp en d ix of this article. Proponents of the rational e x p ec tations approach, however, doubt that such constraints can restore the potency of activist policies and gen erate exploitable Phillips curves. T hey contend that policymaker in form ation advantages cannot long exist when governm ent statistics are published immediately upon collec tion, when people have wide access to data through the news media and private data services, and when even secret policy changes can be pre dicted from preceding observable (and ob v iou s) econom ic and politi cal pressures. Likewise, they note that fixed contracts permit monetary policy to have real effects only if those effects are so inconsequential as to provide no incentive to re negotiate existing contracts or to change the optimal type of contract that is negotiated. A n d even then, they note, such m onetary changes becom e ineffective when the con tracts expire. M ore precisely, they question the w hole idea of fixed con tracts that underlies the sticky wage case for policy activism. T hey point out that contract length is not in variant to the type o f policy being pursued but rather varies with it and thus provides a weak basis for activist fine-tuning. Finally, they insist that such p oli cies, even if effective, are inappro priate. In their view , the proper role for policy is not to exploit in form ational and contractural con straints to systematically influence real activity but rather to neutralize 17 the constraints or to m inim ize the costs o f adhering to them. T hus if people fo rm biased price forecasts, then the policym akers should publish unbiased forecasts. A nd if the policy authorities have inform ational ad vantages over private individuals, they should make that inform ation public rather than attempting to exploit the advantage. T hat is, if inform ation is costly to collect and process, then the central authority should gather it and make it freely available. Finally, if contractual w ages and prices are sticky and costly to adjust, then the authorities should m inim ize these price adju st ment costs by follow in g policies that stabilize the general price level. In short, advocates o f the rational expectations approach argue that feasibility alone constitutes insuffi cient justification fo r activist p oli cies. P olicies should also be socially beneficial. A ctivist policies hardly satisfy this latter criterion since their effectiveness is based on deceiving people into m aking expectational errors. T h e proper role for policy is not to influence real activity via deception but rather to reduce in for mation deficiencies, to eliminate erratic variations o f the variables under the policym akers’ control, and perhaps also to m inim ize the costs of adju sting prices. VII. CONCLUDING COMMENTS T h e preceding paragraphs have traced the evolution o f Phillips curve analysis. T h e chief conclusions can be stated succinctly. T h e Phillips cu rve concept has changed radically over the past 25 years as the notion o f a stable enduring trade-off has given w ay to the p olicyineffectiveness view that no such tra d e-off exists fo r the policym akers to exploit. Instrumental to this change w ere the natural rate and rational expectations hypotheses, respectively. T h e form er says that trade-offs arise solely from exp ecta tional errors w hile the latter holds that system atic m acroeconom ic sta bilization policies, by virtue of their very predictability, cannot possibly generate such errors. Taken to gether, the tw o hypotheses im ply that systematic dem and management policies are incapable o f influencing real activity, contrary to the predic tions of the original Phillips curve analysis. O n the positive side, the tw o hy potheses do im ply that the g overn ment can contribute to econom ic stability by follow in g policies to minim ize the expectational errors that cause output and em ploym ent to deviate from their norm al fullcapacity levels. F o r exam ple, the authorities could stabilize the price level so as to eliminate the surprise inflation that generates confusion be tween absolute and relative prices and that leads to perception errors. Sim ilarly, they cou ld direct their efforts at m inim izing random and erratic variations in the m onetary variables under their control. In so doing, not only w ould they lessen the num ber o f forecasting mistakes that induce deviations from output’ s nat ural rate, they w ou ld reduce policy uncertainty as well. Besides the above, the natural rate-rational expectations school also notes that m icroecon om ic structural policies can be used to achieve what m acro demand policies cannot, namely a permanent reduction in the unem ploym ent rate. F or, by im p rovin g the efficiency and perform ance of labor and produ ct markets, such m icro policies can low er the natural rate of unem ploym ent and shift the vertical Phillips curve to the left. A sim ilar argum ent was advanced in the early 1960s by those w h o advocated structural policies to shift the Phillips curve. It is on this point, therefore, that one should look for agreement betw een those who still affirm and those w h o deny the existence of exploitable inflationunem ploym ent trade-offs. APPENDIX A SIMPLE ILLUSTRATIVE MODEL T he policy ineffectiveness p ro p o sition discussed in Section V of the text can be clarified with the aid o f a simple illustrative model. T he model consists o f four com ponents, namely an (in v erted ) expectationsaugmented Phillips curve (1 ) U N- U = ( l / a ) ( p - p e) , an inflation-generating mechanism (2 ) p=m +e, a policy reaction function or feed back control rule (3 ) m = c ( U - i — U T) — d ( p - i — Pt )+ M > and a definition of rational inflation expectations (4 ) pe= E [ p | I ] . H ere U and U n are the actual and natural rates of unem ployment, p and pe the actual and expected rates o f inflation, m the rate of monetary grow th per unit of real output (the latter assumed to be constant except for transitory disturbances), e and fi are random error terms with mean values of zero, E is the expectations operator, I denotes all inform ation available when expectations are form ed, and the subscripts T and — 1 denote target and previous peri od values of the attached variables. O f these four equations, the first expresses a trade-off between unem ployment (relative to its natural level) and surprise (u n exp ected ) inflation.1 E quation 2 expresses the 1 There exists a current dispute over the proper interpretation of the Phillips curve equation 1. The rational expec tations literature interprets it as an aggregate supply function stating that firms produce the normal capacity level of output when actual and expected inflation are equal but produce in ex cess of that level (thus pushing U below U N) when fooled by unexpected inflation. This view holds that firms mistake unanticipated general price in creases for rises in the particular (rela tive) prices of their own products. Surprised by inflation, they treat the price increase as special to themselves 18 iale u f i n f l a t i o n p as the sum o f the grow th rate o f m oney m and a ran dom shock variable e, the latter as sumed to have a mean (e x p e cte d ) value o f zero. In essence, this equa tion says that inflation is generated by excess m oney grow th and tran sitory disturbances unrelated to m oney grow th. Equation 3 says that the policy authorities set the current rate of m onetary grow th in an effort to correct last period’s deviations of the unem ployment and inflation rates from their predeterm ined tar get levels, U t and pT. A lso, since m oney grow th cannot be controlled perfectly by the feedback rule, the slippage is denoted by the random variable jx with a mean of zero that causes m oney grow th to deviate unpredictably from the path intended by the authorities. N ote that the disturbance term fx can also repre sent deliberate m onetary surprises engineered by the policy authorities. Finally, the last equation defines anticipated inflation pe as the m athe matical expectation o f the actual in flation rate conditional on all in for mation available when the expecta tion is form ed. Included in the set o f available inform ation are the in flation generating mechanism, the policy reaction function, and the values o f all past and predeterm ined variables in the model. T o derive the policy-ineffectiveness result, first calculate mathematical expectations of equations 2 and 3. R em em bering that the expected values o f the random terms in those equations are zero, this step yields the expressions and so expand output. A n alternative interpretation views the equation as a price-setting relation according to which businessmen, desiring to main tain their constant-market-share rela tive prices, raise their prices at the rate at which they expect other businessmen to be raising theirs and then adjust that rate upward if demand pressure ap pears. Either interpretation yields the same result: expectational errors cause output and unemployment to deviate from their natural levels. The devia tions disappear when the errors vanish. (5 ) pe= m e and (6) me==c(U-i—UT) — d ( p - i — Pt) w hich state that, under rational e x pectations and systematic feedback policy rules, the anticipated future rate of inflation equals the expected rate of m onetary grow th which in turn is given by the deterministic (k n o w n ) com ponent of the m one tary p olicy rule. T h e last step is to substitute equations 2, 3, 5, and 6 into equation 1 to obtain the reduced form expression (7) UN- U = ( l / a ) ( e + f t ) which states that deviations o f un em ploym ent from its natural rate result solely from inflation surprises caused by random shocks. T o see the policy ineffectiveness result, note that only the unsystem atic or unexpected random co m p o nent o f monetary policy, m — enters the reduced form equation.2 T h e systematic com ponent is absent. T h is means that systematic (ru lesbased) m onetary policies cannot affect the unem ploym ent rate. O nly unexpected m oney grow th matters. N o Phillips curve trade-offs exist for systematic policy to exploit.3 2 N ote that both the monetary-surprise equation m — m e = u and the pricesurprise equation p — pe= e embody the famous orthogonality property accord ing to which forecast errors m — me and p — pe are independent of (orthogonal to) all information available when the forecast is made. In particular, the forecast errors are independent of the past and predetermined values of all variables and of the systematic com ponents of the policy rule and inflationgenerating mechanism. This is as it should be. For if the errors were not independent of the foregoing variables, then information is not being fully ex ploited and expectations are not ra tional. 3 O f course random policy could affect output. That is, the authorities could influence real activity by manipulating the disturbance term n in the policy re action function in a haphazard unpre dictable way. Randomness, however, is not a proper basis for public policy. 19 Earnings and Capital Accounts Highlights Net earnings before payments to the United States T reasury in creased in 1984 by $122,347,910.63 to $1,326,997,413.31. S ix percent statutory dividends am ounting to $4,554,218.39 were paid to Fifth District member banks, and the sum of $1,316,246,794.92 was turned over to the U nited States Treasury. Capital stock rose by $6,196,400 to $80,360,450 as mem ber banks increased their shareholdings in this Bank, as required by law, to reflect the rise in their own capital and sur plus accounts. T he B ank’s surplus account increased $6,196,400 to $80,360,450. Discount Rate O n A pril 9 the discount rate was raised from d>/l 2 percent to 9 percent. T his change, the first since late 1982, was undertaken in the light of a relatively wide spread between short-term market rates and the dis count rate. T he discount rate was then reduced to Sy2 percent effective Novem ber 21. This reduction was taken against the background of growth in M l and M 2 in the low er part of the desired ranges and in the context of distinct m oderation in the pace of business expansion, o f rela tive stability in producer and co m modity prices, o f the restrained trend of wages and costs, and of the co n tinued strength of the dollar inter nationally. F or essentially these same reasons, and to bring the rate into closer alignment with short term rates generally, the discount rate was subsequently reduced to 8 percent on D ecem ber 24. New Service Product Developm ent of the F ed Online X change called F O X (a new elec tronic access to inform ation and services at the Fed through a m icro com puter for depository institu tions) began in 1984 with a pilot program in N ovem ber for three par ticipating D istrict institutions. Initial services will include origination, re ceipt, and return of A C H payments ; provision o f inform ation on co n temporaneous required reserves 20 ( C R R ) ; and filling cash order re quests. T ransfer of funds and secur ities and other on-line services will he added to the T^(-----)"x 1 *n r& n.......... gnm ^ ----- in 11 ‘ 1985. Electronic Payments T he off-line w ire transfer oper ations in the B altim ore and Char lotte O ffices w ere consolidated with those at the R ichm ond O ffice on January 3, 1984. A s a result, all Fifth District funds transfers, both on-line and off-line, are handled by the R ichm ond O ffice. Communications and Data Processing T he year 1984 saw the establish ment of three additional bank com puter links to the Fifth District Com m unications System, raising the total num ber o f com puter interfaces to eleven. Term inals w ere installed in seven financial institutions during the year. F ou r on-line institutions m erged with others, raising by three the net total to 112 such institutions handling w ire transfer of funds through direct connections to the Fifth D istrict C om m unications Sys tem. O f these institutions, 47 are also processing securities transfers (C P D s ). Im plementation of the Federal R eserve L o n g R ange A utom ation Program , which involves standard ization of applications software throughout the Federal R eserve System, continued during 1984. T he C ontem poraneous R equired R e serves ( C R R ) System and the Cus tomer Inform ation System (C I S ) were installed in F ebruary. T he developm ent of the resource-shared General L edger M odule of the Inte grated A ccou n tin g System was com pleted in A ugust. Community Affairs and Economic Information In February 1984, the B oard of G overnors redefined the role of the Com m unity A ffa irs O fficer ( C A O ) at each R eserve Bank, and approved a new set of responsibilities for the position. Basically, the C A O was given the responsibility o f coord i- nating the B ank’s educational efforts in the area of com m unity reinvest ment and facilitating the provision of inform ation to lenders, com m unity groups, system exam iners, and others about the C om m unity R ein vestment A ct and successful p ro grams for com m unity investment, reinvestment, small business lending, and econom ic developm ent. D uring the first quarter, the C om munity A ffairs and E con om ic In fo r mation section launched C R O S S S E C T I O N S , the newest of the Bank’s publications. T h is publica tion is a quarterly newsletter co n cerning business and econom ic de velopm ents in the Fifth District.
