F ed eral R eserve Bank of St. Louis
Review
November 1985

In This Issue . . .




In the first article of this Review, M ichael T. Belongia and C ourtenay C. Stone
investigate the validity of a conventional policy recom m en d ation am ong agricul­
tural econ om ists: that red u cin g the federal budget deficit is a n ecessary co m p o ­
nent of any effort to increase agricultural exports. W hile widely a ccep ted , Belon­
gia and Stone argue that at least three propositions m ust be tru e for this
recom m en d ation to have som e legitim acy. The first two propositions require
positive relationships betw een deficits and the real rate of interest an d betw een
the real rate of interest and the real value of the dollar. The last proposition
requires a negative relationship betw een the real value of the dollar and real farm
exports.
Belongia and Stone investigate these propositions by explaining the relevant
eco n om ic theory behind each and offering both sim ple an d detailed statistical
evidence regarding the predictions of these theories. Their analysis indicates
there is considerable doubt that larger budget deficits have raised real interest
rates and, consequently, the real value of the dollar. They do find su p p ort for the
third proposition relating the exch an ge rate to farm exports. In view of the o th er
conflicting evidence, however, the authors co n clu d e that it is safe to say the
relationship betw een budget deficits and farm exp orts is unresolved.
In the secon d article in this issue, "M onthly E co n om ic Indicators: A Closer
Look at the Coincident Index,” Keith M. Carlson d iscu sses the C om m erce D epart­
m en t’s com p osite index of coincident indicators. This index co n d en ses the
inform ation from the m ost im portant m onthly e co n om ic ind icators into one
sum m ary m easure. The co m p o n en t indicators from w hich the co m p o site index is
derived include em ployees on nonagricultural payrolls, personal incom e less
transfer paym ents in con stan t (1972) dollars, industrial produ ction , an d m an u fac­
turing and trade sales in co n stan t (1972) dollars.
After describing the coinciden t index and its co m p o n en t indicators, Carlson
d iscu sses the C om m erce D ep artm en t’s scoring system . This system is b ased on
seven criteria. The focus of the article, however, is on the criterion of cyclical
p erform ance. An exam ination of the co m p o n en t ind icators reveals th at each
ind icator generally conform s well with the National Bureau of E co n om ic Re­
search 's business cycle reference points, particularly w hen viewed with som e
perspective.

Would Lower Federal Deficits
Increase U.S. Farm Exports?
Michael T. Belongia and Courtenay C. Stone

NY farm policy experts believe that U.S. agri­
cultural exports w ould be increased significantly if
federal budget deficits w ere red uced . One su ch ex­
pert, for exam ple, has co m m en ted that “a m ore nearly
balanced federal budget probably w ould do as m uch
as anything to im prove o u r agricultural export perfor­
m an ce.”1 O ther analysts also have predicted that the
farm outlook will rem ain bleak until this nation d e­
velops “a credible plan to red u ce the en orm ous Fed ­
eral budget deficits.”- This view is so pervasive that it
might now be con sidered the conventional wisdom
on the subject.'
If this view is valid, it has im portant im plications for
d om estic farm policy legislation, including the p en d ­
ing farm bill.1 If federal budget deficits have seriously
red u ced farm exports and, consequently, real farm
incom e, then legislators should focus primarily on
reducing the deficit to revive farm exports and incom e;
in this case, cu rren t com m odity program s may need
little fundam ental change o nce the deficit has been
red u ced . If budget deficits have not contributed m ate­
rially to the decline in farm exports, however, then
focusing attention on deficit red u ction m easures may

30 f course, this view is not confined solely to farm policy experts. It is
held by a large number, perhaps even the vast majority, of policy
analysts. For similar statements about the effect of deficits on
exports, see Clark (1985), Downs (1985), Kraft (1985) and
Modigliani (1985).
“The omnibus farm legislation currently in effect is a four-year bill that
was passed in 1981. Congress is now debating the issues encom­
passed by a new four-year bill, renewal of existing legislation, or
returning to the “ permanent" legislation of the 1930s and 1940s that
covers most major commodities.




divert attention from m ore fundam ental changes that
might be required in farm com m odity program s. The
purpose of this article is to describe the theoretical
links betw een federal budget deficits and U.S. farm
exports and to exam ine the em pirical evidence on
these links.

THE FARM E X P O R T PR O BLEM
singled out as a strong, p erh ap s the prim aiy, suspect
in attem pts to explain w hy farm exp orts have declined
so sharply in recen t years. A p rim a fa c ie case can be
m ade for the deficit explanation bv simply looking at
the recent relationship betw een exp orts and the defi­
cit; this com p arison is show n in ch art 1 for sem i­
annual data since 1973.
If we look only at the past four years, we see that
nom inal farm exp orts declined from 1981 through
1983, rose marginally last year, and have fallen again
through early 1985. During this sam e period, federal
deficits, as m easured by the national incom e a c ­
counts, skyrocketed, rising from $64 billion in 1981 to
$176 billion in 1984. The association betw een rising
deficits and falling exp orts app ears to be obvious.
Yet, w hen the entire period is exam ined, this co n ­
clusion is not so obvious. Deficits w ere rising and
falling from 1973 (when it w as only $6 billion) to 1981.
This period w as one of generally rising farm exports.
Thus, the view that rising deficits adversely affect
exp orts is one that seem s to be based primarily on
evidence from the m ost recen t period. Such a narrow
focus necessarily raises questions about the generality
of the presum ed relationship and the likely effect of
policies designed to exploit the relationship.
To get a b etter perspective on the relationship b e­
tween deficits and farm exports, w e m ust focus on the

theoretical relationships that tie them togeth er and
the em pirical support for these underlying theories.

TH E LINKS IN T H E D EFICIT-FARM

The conventional view of the links betw een deficits
and farm exp orts is show n in figure 1. In this fram e­
work, the problem s of red u ced exports, expan d ed
im ports and political m easures prom oting protection
for d om estic industries can be traced backw ard, stepbv-step, to their so u rce: large, persistent federal
budget deficits. An exam ination of figure 1 show s that
there are at least three key eco n om ic relationships
that m ust exist for this conventional view to be valid.
First, o th er things unch an ged, deficits m ust be re­

differences in inflation betw een the United States and

low er federal deficits will increase farm exp orts by
reducing real rates of interest and, thus, the real for­
eign exchan ge rate of the dollar, relies on the validity
of these links. We analyze these links in turn in the
following sections.

LINK # 1 : WOULD LO W ER D EFIC ITS
REDUCE REAL IN T ER EST RA TES?
Choosing Appropriate Deficit and
Interest Rate Measures
One basic problem with tiying to discern the rela­
tionship betw een deficits and interest rates is that the
m easures w e observe m ust be "ad ju sted ,” both to
eliminate potentially confounding influences and to
focus the analysis on those m easures that are em p h a­
sized by the underlying eco n om ic theoiy. The deficit
m easure can be adjusted in a variety of wavs. Three
com m only used p ro ced u res are: (1) to adjust for the
im pact of inflation by using a real deficit m easure; (2)
to adjust for the size of the econ om y by dividing the
deficit by som e m easure of spending o r saving; and (3)
to rem ove the business cycle influences on the deficit.
Interest rates also m ust be adjusted appropriately if
we are to cap tu re the deficit's influence on them .
Market interest rates — the ones that we see quoted



every day — ca n be thought of as the sum of two basic
com p on en ts: the exp ected inflation rate and the ex­
p ected (or ex a n te) real rate of interest." Changes in the
deficit per se should have no effect on the exp ected
rate of inflation unless the Federal Reserve is exp ected
to m onetize the deficit (that is, increase its p u rch ases
of governm ent bonds).7 Since ch an ges in the exp ected
rate of inflation, how ever, cau se nom inal interest rates
to change an d obscu re the im p act of ch an ges in the
deficit, w e m ust rem ove the influence of ch an ges in
inflation exp ectation s; w e m ust focus on the deficit’s
im pact on the exp ected real rate of interest.

The Conventional View o f the Deficit’s
Impact on the Real Rate o f Interest
The view that larger deficits increase the exp ected
real rate of interest is based on the validity of the
"interest-rate crow ding o u t” p h en om en on. Interestrate crow ding out is d em onstrated graphically in

rates and between ex ante and ex post interest rate measures, see

problems associated with attempts to measure real interest rates,
see Brown and Santoni (1981).

inflation, see Protopapadakis and Siegel (1984) and Weintraub
(1981).

that influences th ese borrow ing and lending decisions
separately, and that is determ in ed jointly by the inter­
actions of all borrow ers and lenders, is the real rate of
interest.

Using figure 2, it is easy to show how a larger deficit
could increase the real rate of interest. If all oth er
things rem ain the sam e, a larger deficit increases the
dem an d in the credit m arket to D' and results in a
higher price of credit as the real rate of interest rises to
r,. The additional resou rces that the governm ent ob­
tains com e partly from additional saving (for exam ple,
people red u ce their consum ption) and partly from
reductions in non-governm ent borrow ing (for exam ­
ple, private investm ent declines). The larger deficit
and the resulting higher real interest rate have thus
crow ded out, or red u ced , private secto r consum ption
and investment.
Of course, the extent to w hich the real rate of inter­
est actually in creases u n d er the conventional view
d epends on the specific slopes of the dem and and
supply cuives; the flatter are the dem and and supply
curves, the sm aller the rise in the real rate of interest.

An Alternative Theoretical View o f the
Impact o f Deficits
Interest-rate crow ding out, as d ep icted in figure 2, is
predicated on the view that increases in the deficit per
se have little effect on the supply of o r the dem and for
credit bv co n su m ers and private firms. Instead, co n ­
sum ers and private firms respon d by moving along
their u nchanged dem an d and supply cuives in re­
sponse to changes in the real rate of interest p rodu ced
by the increased governm ent deficit.
An alternative view of how people respon d to
changes in governm ent deficits suggests that the real
rate of interest is essentially unaffected by governm ent
deficits." This view states that people see deficits as

T h is view has been popularized by Barro (1974) and Seater (1982),
among others. For a recent discussion of the conventional and
alternative theoretical relationships between deficits and interest
rates, see Rasche (1985) and Tatom (1985); for recent evidence
supporting this alternative view, see Kormendi (1983) and Protopapadakis and Siegel (1984).

implied taxes that eventually m ust be im posed on
their future incom es to repay the larger governm ent
obligations. Thus, larger deficits today are equated
with larger future taxes an d red u ced future after-tax
incom es. As a result, an increase in the deficit red u ces
peop le’s perm anent incom es; this, in turn, red u ces
the private land, thus, the total) dem an d for credit (to
D), while increasing private saving and, thus, the su p ­
ply of credit (to S). As show n in figure 2, although defi­
cits crow d out private investm ent an d consum ption,
they have no appreciable im pact on the real rate of
in te re st, w h ich re m a in s u n ch a n g e d at r„. The
crow ding-out is d irect; it does not take p lace through
increased real interest rates.

Deficits and Expected Real Interest
Rates: Some Casual Evidence
The conventional view suggests that, o th er things
the sam e, larger deficits are associated w ith higher
exp ected real interest rates; the alternative view sug­
gests that they are not.
Chart 2 displays the behavior of one adjusted deficit
m easure and one m easure of the e x p ected real inter­
est rate that, accord in g to conventional theory, is in­
fluenced by federal deficits. The deficit m easure used
is the real cyclically adjusted deficit div ided by p oten ­

An exam ination of ch art 2 provides som e evidence
that the real interest rate does not respon d to changes

method: six-month-ahead inflation forecasts for the consumer price
index (CPI) were derived from the Livingston survey data. These
expected inflation figures were then subtracted from the quarterly
averages for the six-month Treasury bill rate for the quarters in
which the surveys were taken. For more details on this method, see

years. Similarly, the exp ected real rate rose sp e cta cu ­
larly from early 1980 to early 1982 w hen the deficit

rate has declined considerably, vet the deficit has

Chart 3 sum m arizes the relationship betw een the

increases (decreases) in the deficit generally w ere as­
sociated with increases (decreases) in real interest
rates, then the vast m ajority of the associated pairs of

Thus, it app ears that eco n o m etric studies provide
only weak evidence to support the view that federal
deficits have a significant influence on interest rates."

LINK # 2 : WOULD LO W ER U.S. REAL
IN T ER EST RATES RED UCE TH E
FOREIGN EXCHANGE VALUE O F TH E
DOLLAR?
Most farm com m odities trad ed in international
m arkets are priced in U.S. dollars regardless of w here
they are p ro d u ced . Consequently, a set of events that
raised the value of the dollar in term s of Brazilian
cruzeiros, for exam ple, w ould make Brazilian soy­
beans less expensive than U.S. soybeans. Nations that
im port soybeans cou ld use their dollars to p u rch ase
cruzeiros and, hence, p u rch ase Brazilian soybeans
m ore cheaply than before. B ecause of this relation­
ship, changes in farm exports are linked to changes in
the value of the dollar.
While we typically think of the value of the dollar visa-vis one or an o th er specific cou n try's cu rren cy — for
exam ple, the Jap an ese yen, the Fren ch franc o r the
West German mark — su ch bilateral exchange rates bv
them selves, do not provide a clear picture of w hat is
happening to the overall value of the dollar in foreign
exchange m arkets. Instead, an /nde,v of the dollar’s
value often is used to incorporate information about
the m ovem ent of the dollar relative to o th er m ajor
cu rrencies. One index, called the trade-w eighted ex­
change rate of the U.S. dollar, enables us to determ ine
what is happening to the dollar's value relative to the
cu rren cies of o u r m ajor trading p artners."
The foreign exch ange value of the dollar is the
relative price of the U.S. dollar in term s of o th er n a ­
tion s’ cu rren cies. The actu al value of the dollar at any
time is d eterm ined by the factors that underlie the
dem and for and supply of dollars in foreign exchange
m arkets.
There currently is som e controversy over w hich
factors determ ine exch an ge rates and the relative in­
fluences they have on exchange rate m ovem ents at

any p articu lar m om ent.' There is, however, a fairly
general analytical framework that suggests four fac­
tors as the main influences on the behavior of ex­
change rates: (1) differences in inflation rates betw een
countries; (21 differences in real interest rates betw een
countries; (3) differences in real eco n o m ic conditions
that influence trade p attern s; and (41 differences in
political and o th e r risks associated w ith investm ent in
specific countries."' We focus on the effects of changes
in the first two factors on exch an ge rate m ovem ents.
Unfortunately, ch an ges in the rem aining two factors
can make it difficult to d ecip h er the actu al im p acts of
changes in inflation an d real interest rate differentials
on the exch an ge rate at any given m om ent.

Adjusting the Exchange Rate fo r
Differences in Inflation Across Nations
Theoretical co n sid eration s suggest that ch an ges in
bilateral and trade-w eighted foreign exch an ge values
of the dollar are inversely related to differences be­
tw een U.S. and foreign inflation rates. If this inflation
differential (U.S. m inus foreign) is positive, the value of
the dollar will decline over tim e; if the inflation differ­
ential is negative, the dollar’s foreign exch an ge value
will rise.
This relationship, called pu rch asin g p ow er parity, is
based on the notion that sim ilar goods traded in world
markets m ust co m m an d sim ilar prices, regardless of
w here they are bought and sold. F or exam ple, if a
bushel of corn co sts $1.50 in the LInited States and C3
in the United Kingdom, an exch an ge rate of £ 2 per
dollar w ould "equalize” the price of U.S. an d U.K. corn
to all p u rch asers. If inflation in the United States drove
the price of corn to S3 p er bushel, then, o th er things
the sam e, the exchange rate w ould have to fall to £ 1
per dollar to bring the price of U.S. co rn back in line
with U.K. corn in w orld m arkets.
Of course, if changes in the value of the dollar were
simply the result of ch an ges in these inflation differen-

,5For example, one analyst has noted that “there is no consensus on
how exchange rates are determined. The interpretations vary widely
among the various theories, ranging from the traditional approach of
trade-oriented demand and supply factors, to the modern approach
of asset-market mechanism and expectations. The analysis of cur­
rency determination is complicated by the interdependence of the
exchange rates, monetary and other economic policies, and factors
affecting economic and financial performance.” Poniachek (1983),
p. 2.3.3.

tials, exchange rate m ovem ents w ould be neutral with
respect to trade p atterns. Indeed, o th er things u n ­
changed, exchange rate m ovem ents con sisten t with
purchasing pow er parity will preserve cu rren t trade
patterns.
Exchange rates are affected bv o th er factors, how ­
ever, so that their m ovem ents are not con sisten t solely
with purchasing pow er parity conditions. If exchange
rates rise m ore (or fall less) than inflation differentials
w arrant, prices of U.S. goods will rise relative to similar
goods sold by o th er cou n tries; if exchange rates rise
less (or fall more) than inflation differentials w arrant,
prices of U.S. goods will fall relative to foreignp rodu ced goods.
This discussion suggests that, if we want to assess
the effect of exchange rate m ovem ents on exp orts in
general, and farm p ro d u cts in particular, w e should
look at the m ovem ent in exch an ge rates after adjusting
for the effects of inflation differentials. One su ch ex­
change rate m easure is called the real trade-w eighted
exchange rate for the U.S. dollar.'7

The Impact o f Real Interest Rate
Differences on the Real Exchange Rate
Theoretical con sid eration s suggest that changes in
the real trade-w eighted exchange rate should be posi­
tively related to ch anges in the real interest rate differ­
ential (U.S. m inus foreign). If U.S. real interest rates rise
relative to foreign real rates, o th er things the sam e, the
real trade-w eighted value of the dollar should rise; if
U.S. real interest rates fall relative to foreign real rates,
the real trade-w eighted value of the dollar should
decline. The presum ption is that a positive real rate
differential will attract foreign capital, while a negative
differential will make investm ent abroad m ore a ttra c­
tive. Thus, ch an ges in the real rate differential should
cau se similar ch an ges in the real trade-w eighted ex­
change rate.

These data suggest that the link betw een the real
interest rate and the real exch an ge rate is not esp e­
cially reliable. For exam ple, average real interest rate
differentials w ere approxim ately the sam e in the 1 9 7 5 78 and 1 9 8 2 -8 5 periods, vet the real exch an ge rate was

interest differential and m ovem ents in the real ex­
change rate. It is a scatter-d iagram of changes in the
real interest rate differential and the associated per­
cen t changes in the real exch an ge rate. O ther things
unchanged, eco n om ic theoiy predicts that the points
should lie predom inantly in the first (I) and third (III)
quadrants; positive (negative) ch an ges in the real in­
terest rate differential should be associated with posi­
tive (negative) p ercen t ch an ges in the real exchange
rate. This is not the case: the data points lie mainly in
quadrants II and IV.
The line labeled R, is the regression line relating the
p ercen t ch an ges in tire real trade-w eighted exchange
rate associated with the ch an ges in the exp ected real
interest rate differential. It should slope upw ard from
left to right; instead, it slopes dow nw ard, suggesting
that an increase (decrease) in the real interest rate
differential is associated with a d ecrease (increase) in
the real exch an ge rate. This estim ated inverse rela­
tionship, however, is not a statistically significant one;
that is, the claim that there is no sim ple linear relation­
ship betw een these variables can n ot be rejected at
standard statistical significance levels. This puzzling
result again suggests that d eciphering the effect of
changes in real interest rate differ entials on exchange
rate m ovem ents requires detailed and careful e co n o ­
m etric analysis.

interest rate differentials actually affect real exchange

“ The estimated coefficients from this type of statistical study are
strictly valid only for small changes in variables. Therefore, the
example presented should not be expanded to conjecture, for
example, that a 100-basis-point change in the interest differential
would cause a 2.3 percent change in the dollar’s real value.

The line labeled R, is the regression line relating the

The negative slope, however, is not statistically signifi­

elasticities are all negative as exp ected . Although the
estim ated elasticities range from —0.3 to —2.3, the
m ore recen t ones run close to — 1, indicating that a 1
percen t drop in the real exch an ge rate will, after suf­
ficient time passes, ind u ce a 1 percent rise in total
m erchandise exports.
Two recent studies focused specifically on the effect
of changes in the exch an ge rate on agricultural ex­
ports.’ 1 After estim ating a simple quarterly red uced form equation for the real value of farm exports, they
find that a 1 p ercen t fall in the real value of the dollar

will increase the real value of farm exp orts bv 0.7

unlike the previous two links, the third link in the
chain running from deficits to farm exp orts has both
theoretical and em pirical support.

ou r n atio n ’s exporting sectors, p rod u cers of farm
com m odities in particular, will continue to suffer until
federal deficits are red u ced an d U.S. interest rates are
brought down.
In this article, w e exam ined three vital links in the
conventional argum ent that ties the deficit to farm
exports. With resp ect to the first link, w e noted that
there is considerable theoretical controversy over
w heth er larger deficits actually cau se real interest
rates to increase. We found little em pirical evidence to
support this view.
Second, w e noted that, even if low er deficits did
result in low er U.S. real interest rates, they w ould not
necessarily have a salutary im p act on the real ex­
change rate. Apparently, o th er influences on the real
exchange rate have offset the effect, if anv, of changes
in real interest rate differentials in recent years.
Among these o th er factors m ay be "the strong perfor­
m an ce of the U.S. econom y, confidence in the strength
and stability of the political system in the United
States, capital flight from debtor countries, [and] a
substantial shift in the external position of Am erican
banks. ” 6 The im portant point is that there is little

em pirical evidence to show that ch an ges in the real
interest rate differential have had a significant im pact
on m ovem ents in the real exch an ge rate during the
past 13 years.
Finally, w e show ed that, although U.S. farm exp orts
are inversely related to the real exch an ge value of the
dollar, the dem an d relationship is inelastic and ex­
change rate m ovem ents have th eir full effect only over
a considerable tim e period. However, even though
low er exch an ge rates would, over time, increase U.S.
farm exports, the failure of the first two links to be
supported suggests that w e can n o t necessarily expect
that low er deficits will result in a low er value of the
dollar in foreign exch an ge markets.-7
None of the d iscussion above should be taken as
evidence that deficits p er se are eith er good or h arm ­
less. Nor does it prove that larger deficits have had no
adverse effect on real interest rates, on the foreign
exchange value of the dollar o r on farm exports. Unfor­
tunately, at the present tim e, there con tin u es to be

in the dollar's fortunes since late 1980 may [be] related to (i) the
election of a new administration committed to a more conservative
approach to financial policies; and (ii) the increased risks associated
with other currencies." Atkinson et al. (1985), pp. 37 and 39.

ECISIONS relating to m onetaiy policy are based
on a considerable volum e of eco n om ic information.
One of these p ieces of inform ation is the cu rrent
status of eco n om ic activity. Recent eco n om ic perfor­

There are m any eco n o m ic indicators released each

The U.S. D epartm ent of C om m erce's B usiness Con­

a substantial subset, of these indicators could provide
a confusing picture to even the m ost astu te analyst.
Fortunately, w ading through su ch a m orass is not

Composite Index o f Coincident
Indicators
The com p osite index of coin cid en t indicators is a
sum m ary m easure designed to signal changes in the
direction of eco n o m ic activity. The index m easures
the behavior of the four eco n om ic time series d e ­
scribed above, w hich show sim ilar timing at business
cycle turn s but rep resen t widely differing activities or
sectors of the econ om y. These four co m p o n en ts w ere
selected w ith the help of a detailed scoring system
that p laces p articu lar em phasis on cyclical timing.
The ch o ice of coin cid en t ind icators w as based up on a
com p arison of the timing ch aracteristics of the p artic­
ular series w ith reference dates (business cycle tu rn ­

erage of those ch an ges. This prevents the m ore volatile
series from dom inating the index. A w eighted average
of these stan d ard ized ch an ges is then co m p u ted with
the “b etter perform ing” series assigned m ore weight.
These w eighted averages are then cu m u lated into an
index. The final step is to “tren d -ad ju st” this index so
that its long-term average grow th rate (since 1948)
equals the average of the tren d in its four co m p o n en ts.
This trend, w hich is sim ilar to real GNP, can be viewed
as a linear approxim ation of the average grow th rate in
eco n om ic activity.

CRITERIA USED TO EVALUATE
ECONOMIC INDICATORS
The BEA u ses a scorin g system to evaluate e co ­
nom ic tim e series as cyclical in d icato rs/1This system
provides inform ation about w hich series are to be
included in the com p osite index and the relative im ­
p ortance, o r w eight, a ttach ed to ea ch series. Seven
criteria are used to evaluate tim e series; the num erical
scores for th ese criteria are su m m arized in table 2. For
the m ost part, these scores are derived qualitatively.
W here possible, however, there is an attem p t to evalu­
ate quantitatively.
The scoring system , first developed and applied by
Moore and Shiskin in 1966, w as published in 1967. It
was modified by Zarnow itz and B oschan in 1975, but
continues to be sim ilar in the m ost im portant detail.
According to Zarnow itz and Boschan:
The system disciplines and systematizes the judgment
of both reviewer and user of the indicators. It is an
effort to insure that all the important aspects of the
evaluation problem are considered in a consistent
and, to a significant extent, replicable wav.'

Economic Significance
How im portant is the eco n o m ic p ro cess o r variable
for w hich the p articu lar series stands, and w hat is the
breadth of the series coverage in representing the
activity co n ce rn e d ? Scoring for this criterion is su b jec­
tive, depending prim arily on a classification of indica­
tors by “type of e co n om ic p ro ce ss.” A broad h ierarch y
of three levels of e co n om ic variables w as postulated:
(1) C om prehensive outp u t and input aggregates in
real an d nom inal term s; for exam ple, real GNP is

Statistical Adequacy
How well does the given series m easure the e co ­
n om ic variable o r p ro cess in question? The BEA co n ­
siders eight asp ects of this criterion:
(1) Quality of the reporting system — is it set up for
statistical purp oses or is it the by-product of an
adm inistrative program ?
(2) Coverage of eco n o m ic p ro cess — full en u m era­
tion, probability sam ple, etc.
(3) Coverage of time period — full m onth or quarter,
one day per m onth, etc.



(41 Availability of estim ates of sam pling and rep o rt­
ing errors.
(51 Frequency of revisions.
(6) Length of series.
(7) Comparability over time — breaks in the series.
(8) O ther considerations.
This detailed evaluation is co n stru cted to be primarily
quantitative rath er than qualitative.

Cyclical Timing
How consistently does the series coincide w ith su c­
cessive business cycle turns? B ecau se this criterion is
crucial for timely recognition of business cycle turning
points, it is assigned the greatest weight of all the
criteria. A ccording to the BEA, this criterion has four
phases: (1) identification and dating of specific cycles
for the com p on en t series; (2) deciding on reference
dates (depending m ainly on the reference chronology
established by the NBER); (3) m atch in g the specific
cycle turning points with the reference dates; and (4)
scoring the cyclical perform an ce of the p articular
indicator.

Conformity
How regularly do m ovem ents in the specific in d ica­
tor reflect the expansions an d co n tractio n s of the

23

FEDERAL RESERVE BANK OF ST. LOUIS

overall econ om y? For an ind icator to be useful, its
specific cycles m ust parallel business cycles. C on­
formity is defined positively if the ind icato r rises d u r­
ing eco n om ic expansions and declines during co n ­
tractions, and negatively if it m oves countercyclically.
This evaluation consid ers the n um ber of business
cycle phases and how they are m atch ed bv the cycle
m ovem ents of the particu lar indicator. Also exam ined
are false signals associated with specific cycles; that is,
m ovem ents in the indicators that do not m atch gen­
eral expansions an d co n tractio n s. In addition, there is
a consideration of am plitude. F or exam ple, larger
m ovem ents than the average will tend to be m ore
identifiable, thu s contributing to the usefulness of an
indicator.

Smoothness
How prom ptly can a cyclical turn in a series be
distinguished from a directional change associated
with sh o rter m ovem ents? It is desirable that the cycli­
cal m ovem ents of the ind icator are not obscu red by
relatively large and frequent irregular variations. Al­
though there are o th er ways of improving sm ooth n ess
(for exam ple, by calculating a moving average), gen er­
ally su ch p ro ced u res imply a loss of tim eliness.

Timeliness
How prom ptly available is the particu lar series and
how often is it reported ? Two asp ects are considered:
(1) how frequently the figures are com piled, and (2)
how prom ptly the figures are available.

NOVEMBER 1985

Depending on the total perform ance score, weights
are assigned to ea ch in d icator in the co n stru ction of
the com p osite index. F or exam ple, nonagricultural
em ploym ent receives the greatest weight (1.064) be­
cau se of its 87 score, followed by industrial p roduction
(1.028), personal incom e less transfer paym ents in
con stan t (1972) dollars (1.003), and m anufacturing and
trade sales in co n stan t (1972) dollars (.905). These
weights do not differ markedly, although the dif­
ference betw een the largest and the sm allest is
substantial.
Nonagricultural em ploym ent sco res high on all cri­
teria, followed closely by industrial p rodu ction . A c­
cording to table 2, the weight on industrial p roduction
is red u ced by its perform an ce at cyclical peaks and by
the extent to w hich it is revised. Personal incom e
receives a relatively low score, mainly b ecau se of the
revisions. Clearly, the w orst of the co m p o n en ts is
m an u factu rin g an d trad e sales, w hich generally
scores low est by ea ch criterion.
The scores for the co n stru cte d com p osite index are
som ew hat surprising. In particular, the total sco re is
low er than that of both nonagricultural em ploym ent
and industrial p rod u ction . Apparently, this reflects
the fact that the com p osite index is subject to su b stan ­
tial revision, since it has to be revised every tim e any
one of the co m p o n en t series is revised.

CYCLICAL PERFORM ANCE

How large are the revisions? This criteria w as added
separately to the list prep ared by Zarnow itz and
B oschan in 1975. Series that are subject to large revi­
sions, especially if they involve directional change, can
be troublesom e, providing m isleading signals about
the p ace of eco n om ic activity.

The m ost im portant criterion used in the evaluation
of eco n om ic indicators is the cyclical perform an ce of
the ind icator in question. Generally, to be classified as
a coinciden t indicator, an in d icato r m ust turn on
average betw een —3 (3-m onth lead) an d + 1 (1-m onth
lag) at peaks and betw een —1 an d + 3 at troughs. The
differences at peaks an d troughs reflect the historical
distribution of timing. Specific peak and trough dates
for each of the coinciden t indicators are sum m arized
in table 3.

The scores show n in table 2 cover the period from
1948 to 1980. The BEA’s objective w as to develop a
com posite index that red u ces the n um ber of false
signals that m ight arise if one w ere to rely on a single
indicator. The advantage of a com p osite index is that it
will sm ooth out the noise in the co m p o nen t series and
also cap tu re the different eco n om ic p ro cesses rep re­

'No specific cycle, that is, no specific turning point corresponding to the indicated reference is discernible.

T here is considerable variation in the lead-lag time
for the co m p o n en t indicators, although the range gen ­
erally is sm allest at cycle troughs. Personal incom e
less transfer paym ents in 1972 dollars app ears to co in ­
cide closest with the reference dates. Note, however,
this series had n either a peak n or a trough associated
with the 19 6 9 -7 0 recession .
M anufacturing and trade sales show s the greatest
variation around reference dates. F or only four of the
14 turning points did this series coincide. This is the
only series that always leads o r coincides with the
reference dates, however.
Nonagricultural em ploym ent has an excellent re c ­
ord excep t for the 1 9 7 3 -7 5 recession. This recession
was initiated by the OPEC oil shock and w as thus
unique am ong postw ar recession s. The un certain re ­
sponse of firms in deciding w h eth er to retain o r lay off
em ployees in the face of this recession w as no doubt



related to the difficulty of interpreting the shock.
O ther than that period, nonagricultural em ploym ent
turns n ear reference dates, although it tend s to lag
rath er than lead.
The index of industrial p rodu ction has an excellent
record around reference dates, especially the trough
dates. It is not clear, therefore, w hy the BEA scores this
ind icator so low arou n d cycle peaks, but it m ay be due
to subsequent revisions arou n d su ch dates. In recent
years, the specific cycle turning point has been within
± two m onths.
The coinciden t co m p o site index should be ex­
p ected to coincide alm ost identically with the refer­
en ce dates, and in recen t y ears it is very close. In
earlier cycles, however, the difference w as as m u ch as

sion of data b ecau se reference dates are seldom

False Signals
A nother question of interest is the extent to w hich a

lyzed with som e perspective, co n sid er tables 6 and 7.
These tables are co n stru cted like tables 4 and 5, excep t
that a false signal is defined as three successive
m onths of perverse m ovem ent.

During recession s, the record is even better. The
coincident index has a perfect record , as do two of the
com p on en ts. Payroll em ploym ent is perfect excep t
that it kept clim bing during the early stages of the
unusual 1 9 7 3-75 recession.

As tables 6 an d 7 show, the frequency of false signals
drops dram atically. On a p ercen tage basis, the fre­
quency is m inuscule. During expansions, real per­
sonal incom e less tran sfer paym ents em itted only one
false signal in the p ostw ar period, followed closely bv
payroll em ploym ent with only two. B ecause it is a
w eighted average of all four com p on en ts, the co m p o s­
ite index em itted m ore false signals than eith er payroll
em ploym ent o r real personal incom e less transfer

tween nonagricultural em ploym ent and industrial
production, an d these two series also correlate m ost
highly with the com p osite index. Clearly, the m an u ­
facturing and trad e sales series perform s least satisfac­
torily. W hen quarterly averages of the com p on en t in­
d icators are co m p ared with GNP, real personal
incom e less transfer paym ents correlates m ost highly,
followed closely bv industrial produ ction .

SUMMARY
M any e co n om ic ind icators are potential can d id ates
for inclusion in a list of sensitive m easures of the
econom y's cyclical m ovem ents. To simplify the p ro ­
cess of selection, th e Bureau of E co n o m ic Analysis of
the U.S. D epartm ent of C om m erce has co n d en sed the
list to four key indicators and, in turn, has co n stru cted
a single com p osite index of coin cid en t indicators.
This article describes the com p osite index and its four
com p onen t indicators, with special focus on their
cyclical perform ance.
The four co m p o nen ts of the coinciden t index are
industrial produ ction, nonagricultural em ploym ent,
real personal incom e less transfer paym ents, and real
m anufacturing an d trad e sales. These four w ere rated
highest by the BEA using a scorin g system based on

28


seven criteria. On the basis of these criteria, no single
ind icator dom inates the others as a m onthly ind icator
of eco n om ic conditions.
F o r the casual e co n om ic analyst, the least satisfactoiy ind icator w ould be real m anufacturing and trade
sales becau se, of the four series, it is the m ost volatile
on a m onthly basis. Also, it is slow to be released; the
estim ate for a p articu lar m on th is not available until a
m onth and a half later. The release lag for two of the
oth er series is about one w eek for nonagricultural
em ploym ent an d about 15 days for industrial p ro d u c­
tion. Although the basic d ata for real personal incom e
less transfer paym ents are released in about 20 days,
the inflation-adjusted series is not released until the
end of the m onth for the preceding m onth. The co m ­
posite index is released at the end of the m onth, but
the first estim ate for the preced in g m onth is based on
only three of the co m p o n en ts; b ecau se of the rep o rt­
ing lag, real m anufacturing an d trad e sales is exclu d ed
from this first estim ate.
An exam ination of th e cyclical perform an ce of the
coinciden t index and its co m p o n en ts revealed that
each series generally con form ed well with the NBER
business cycle reference dates. This result is not su r­
prising, since turning points in eco n o m ic activity are
am ong the m ost im p ortan t criteria used in the se le c­
tion of coinciden t series.

One key question relating to the cyclical reliability of
an indicator is the extent to w hich it em its false sig­
nals. An exam ination of m onthly m ovem ents of the
indicators show s that they do, in fact, give false sig­
nals, betw een 15 p ercen t and 30 p ercen t of the time.
All of the indicators perform very well, however, w hen
false signals are defined as three successive m on th s of
perverse movement.
Finally, som e insights into the com parative perfor­
m an ce of the coinciden t indicators w ere gleaned from
simple correlation analysis. This analysis indicates
that nonagricultural em ploym ent and industrial p ro ­
d u ction are m ost closely related on a m onthly basis
with the com posite index. These two co m p o n en t se­
ries also receive the greatest weight in the co n stru c­
tion of the index. On a quarterly basis, however, real
personal incom e less transfer paym ents correlates

m ost highly with real GNP. Real m anufacturing and
trade sales generally perform s least satisfactorily.

Personal Incom e Less Transfer
Payments in Constant (1972) Dollars

This series m easures the n u m ber of persons em ­
ployed in nonagricultural establishm ents. Data are
obtained from the establishm ent survey co n d u cted
each m onth by the Bureau of Labor Statistics. The
data are primarily from payroll record s voluntarily
rep orted each m on th to state em ploym ent security
agencies by em ployers in the 50 states and the
District of Columbia. Most of these d ata relate to the
payroll period that includes the 12th of the m onth;
data for federal governm ent em ployees represent
positions o ccu p ied on the last day of the m onth.
Included are full-time, part-tim e, tem p oraiy and
perm an en t w orkers. W orkers on paid leave and
those w ho w orked part of the pay period are in­
cluded. Persons on the payroll of m ore than one
establishm ent are co u n ted each tim e they are re­
ported. E xclu d ed are p ersons on nonpav status for
the entire period due to layoff, strike or leave w ith­
out pay; the self-em ployed an d unpaid volunteer
and family w orkers; farm and dom estic w orkers;
and noncivilian governm ent em ployees.

This series m easures personal incom e less tran s­
fer paym ents in co n stan t (19721 dollars. Because
transfer paym ents rep resen t the largest part of p er­
sonal incom e not a ccru e d in p rodu ction and som e
types of transfer paym ents tend to be co u n te r­
cyclical, th e ir rem oval from p erso n al in com e
p rod u ces a series w ith greater cyclical am plitude.
The cu rrent dollar series is deflated with the im ­
plicit price deflator for pei'sonal consum ption
expenditures.




Personal incom e is the incom e received by p er­
sons from all sou rces, that is, from participation in
production, from transfer paym ents from govern­
m ent and business and from governm ent interest,
w hich is treated like a transfer paym ent. Persons
consist of individuals, nonprofit institutions, pri­
vate noninsured welfare funds an d private trust
funds.
Alternatively, personal incom e is defined as the
sum of w age and salary disbursem ents, o th er labor

incom e, p ro p rietors’ incom e w ith inventoiy valua­
tion and capital con su m p tion adjustm ents, rental
incom e, personal interest incom e and transfer pay­
m ents less personal contributions to social insur­
ance.
Transfer paym ents to p erson s are incom e pay­
m ents, generally in m on etary form, for w hich the
recipients do not ren d er cu rren t services. They
consist of business an d governm ent transfer pay­
m ents. Business tran sfer paym ents include liability
paym ents for personal injury, co rp o rate gifts to
nonprofit institutions and bad debts incu rred by
con su m ers. Government transfer paym ents include
paym ents u n d er the following program s: federal
old age, survivors, disability an d hospital insu ran ce;
supplem ental m edical in su ran ce; state unem ploy­
m ent insu ran ce; railroad retirem ent and u n em ­
ploym ent in su ran ce; governm ent retirem ent; work­
e rs’ co m p en sation ; veterans benefits, including
veterans life insu ran ce; food stam ps; black lung
benefits; supplem ental security in com e; an d direct
relief. Also included are governm ent paym ents to
nonprofit institutions o th er than those for work
u n d er research an d developm ent co n tracts.
The implicit p rice deflator for personal co n ­
sum ption expen d itures (PCE) is a cu rren t w eighted
index (1972 = 100) derived by dividing cu rren t dollar
PCE by co n stan t dollar PCE for each period. It is a
w eighted average of the detailed p rice indexes used
in the deflation of PCE w ith com p osition of the
con stan t dollar PCE in each q u arter as w eights.

base year. It is b ased on 252 series that are co m ­
bined with value-added w eights to create the total
index of industrial produ ction .

Manufacturing and Trade Sales in
Constant (1972) Dollars
This series m easures th e m onthly volum e of sales
of m anufacturing, m erch an t w holesalers an d retail
establishm ents in co n stan t 1972 dollars. The series
is com piled from d ata collected ea ch m on th by the
Bureau of the C ensus in the shipm ents, inventories
and orders survey an d in the m erch an t w holesalers
and retail trade surveys. They are adju sted to
benchm arks from the five-year cen su ses of m an u ­
factures, w holesale trade, and retail trad e an d to
interim annual surveys.
Basic d ata on m an u factu rers’ sales are the value
of their shipm ents for d om estic u se o r exp ort. Ship­
m ents are m easured by receip ts, billings or the
value of p ro d u cts shipped (less discounts, retu rn s
and allowances) an d generally exclu d e freight
charges an d excise taxes.
Deflated sales are co m p u ted as follows: m an u fac­
tu rers’ sales are deflated by industry levels (stan­
dard industrial classification as defined by the Bu­
reau of the Census) prim arily using p ro d u ce r p rice
indexes com bined w ith 1977 p ro d u ct-class sh ip ­

of business using ap p rop riate p ro d u ce r p rice in­
d exes along w ith 1 9 7 7 co m m o d ity -lin e sales
weights; and retail sales are deflated by kind of
