A MICRO VIEW OF THE
TRANSACTIONS MONEY MARKET

Abstract

This paper provides a micro-oriented, price-theoretic perspective on the
transactions money market. Such a perspective is useful for three reasons.
First, it emphasizes that the supply of transactions money will depend on,
among other things, the state of technology in the transactions-moneyproducing industry, the price of transactions money, the cost of factors of
production utilized to manufacture transactions money, and the prices of
substitutes for and complements of transactions money--types of determinants
that are commonly taken into account in the specification of a supply curve
of commodities other than transactions money but have been given either
little attention or ignored in the case of transactions money. Second, a
micro perspective can also deal with the fact that transactions money is not
a homogeneous good--provided that the costs of transforming/transporting the
different money forms to a homogeneous state are specifiable (the divisi a
approach to monetary aggregation notably takes a percentage transformation/
transportation cost approach). Third, a micro perspective affords a framework
for comparative statics--i .e., for estimating the a1 locative and distributive
consequences of such aspects of the market as reserve requirements (a
percentage tax on regulated transactions money producers), i nterest-rate
cei 1ings (transactions money price floors), and improvements in technology Or
innovations (outward shifts of the transactions money supply curve--contrary
to the currently popular approach, which models such innovations as inward
shifts of the demand curve for transactions money).

I.

INTRODUCTION

In reviewing the literature on the concept of transactions money and
on the nature of the transactions money market, it is surprising to note
the tendency with which economists rely on a "macro" perspective. In
analyzing and predicting the level of and changes in transactions money
variables, economists favor (with the possible exception of Pesek 1976)
rule-of-thumb and broad causal arguments at the expense of a more
fundamental "microu-oriented (price-theoretic) approach. To determine
the supply of transactions money, for example, a money multiplier is
standard fare (with assumptions being made about the currency-deposi ts
ratio desired by the public and the reserves-deposits ratio maintained by
the banks).

Little attention is given to the state of technology in the

transactions-money-producing industry, the cost of factors of production
utilized to manufacture transactions money, the price of transactions
money, and the prices of substitutes for and complements to transactions
money; yet, these types of determinants typically are taken into account
in the specification of a supply curve of commodities other than
transactions money.
The prevalence of macro perspectives probably derives from the tilt
toward macro-analysis in the training of economists studying transactions
money. It may also, although less likely, stem from a perception that
micro-analysis is either unfruitful in or inapplicable to the case of
transactions money. This paper attempts to erode such a perception and
to point to how macro-trained economists may benefit from occasionally
wearing micro eyeglasses.

Notwithstanding the "back-of-the-envelope" methodology employed below, a
micro perspective appears to be both tractable and useful. Its usefulness is
two-fold. First, it provides a convenient way of characterizing the
transactions money market.

Why not treat transactions money as a good

produced and consumed by participants in a market (albeit a good with
distinctive attributes and a market with pecul iar features)? Second, a
micro-oriented approach affords a framework for comparative statics. Once the
transactions money market is modeled, "tried-and-tested" micro-analytic
techniques exist for estimating the allocative and distributive impacts of
such aspects of the market as reserve requirements, transactions money price
floors, and changes in technology (innovations).
While future work will hopefully put some empirical meat on the
theoretical bones assembled here, this paper outlines a method for depicting
the market and for undertaking comparative static analyses.

It is a skeleton

at best--open to criticism and elaboration. Nevertheless, it is intended to
show how a micro perspective on the transactions money market may be
developed.

Benefits from such a perspective will perhaps accrue to academics

as well as to "real worldu policymakers who regulate transactions money.

The interaction of the above-outlined supply and demand equations will
determine, according to standard economic analysis, the prevailing price and
quantity of transactions money in the economy.
Leaving aside for now the issue of a precise definition of transactions
money, demanders (i .e., consumers) of transactions money are assumed to
include both firms and individuals. Suppliers of transactions money are
presumed to consist of all firms manufacturing a product capable of being used
for making payments. Transactions money producers, therefore, will include
not only banks but also money market mutual funds, credit card companies, and
any other establishments that supply a good having the ability to serve as a
payments mechanism.

A Toy for Intermediates
The beginner's version of the transactions money market fails to account

for two significant features of the market:

1) the presence of a complex

regulatory matrix; and 2) the fact that transactions money is not a
homogeneous good. While the former characteristic may be readily incorporated
into a micro-analytic model, the latter makes such a model problematic if not
intractable.

13.1.

A Homogeneous Good, but Regulatory Distinctions
The transactions money market is subject to a plethora of federal and

state regulations--reserve requirements, interest-rate ceilings, capital and
insurance requirements, proscriptions against vertical and horizontal
integration by suppliers (e.g., the McFadden Act), credit controls, subsidized
check-clearing services, and entry restrictions (e.g., International Banking

interesting to note that a divisia measure of the quantity of transactions
money (see, for example, Barnett and Spindt 1982) opts for essentially a
percentage transformation/transportation cost approach. An economist relying
on a divisia measure attempts to ascertain the percentage of each particular
form of transactions money that is "pure."

A weight ranging from zero on up

is assigned to each form of transactions money--the greater magnitude of the
weight, the purer the transactions money form.

Weights are determined by the

user cost of each form of transactions money--by the extent to which the
return on a particular form of transactions money to the consumer is less than
the return on an asset valued primarily for its attribute of serving as a
store of value.

A divisia measure is thus a weighted average of various forms

of transactions money--not a simple sum as are M-1, M-2, M-3, and L.
In the two-sector case (pure and nonpure), a divisia approach to
deriving an estimate of the aggregate supply of transactions money may be

the alternative transactions money forms. Such estimation, however, would
probably be subject to severe multicollinearity problems. Specifically, a
properly specified system of equations would have to include the prices of
substitute goods--prices that, depending on the number of transactions money
forms that are deemed to be substitutes, tend to be extremely collinear.

111. WORKING WITH THE MODELS:

COMPARATIVE STATICS

It is possible to analyze the effects of various regulatory and
institutional aspects of the transactions money market. This section will
focus on the allocative and distributive consequences of three such aspects:
reserve requirements, transactions money price floors, and innovations. The
comparative statics of these three aspects will be examined in the context of
the intermediate model--i.e., under the assumption that the supply of
tions money may come from either a regulated or an unregulated sector
and that the good produced by both of these sectors is homogeneous. This
approach is adopted for the sake of simplicity in exposition.

Whenever

possible, however, modifications of the intermediate model will be
noted--modifications necessitated by either the perfect-substitutes-wi th

The fact that net transactions accounts exceeding $26 million are taxed
at a 12 percent rate rather than at a 3 percent rate may be considered by
distilling from the regulated sector those firms with net accounts greater
than $26 million and representing the supply curves of such firms as shown in

Note that the new supply curve is discontinuous at the quantity of

Second, the first-cut depiction of the RR tax does not account for the
transactions money might hold reserves even in the
(1979) conjectures that, without RR,
producers would hold 1 percent reserves.

involves relatively less significant allocative and distributive impacts for
the transactions money market.
Third, the first-cut characterization of the RR tax may easily be
adapted to the perfect-substitutes-with-transformation/transportation case.
One would simply apply tne same analysis after filtering out the "nonpure"
portions of the regulated and nonregulated transactions money supply curves
(under the divisia approach, for example, one might take only a percentage of
the unregulated transactions money supply curve).

In the case of imperfect

substitutes, however, a study of the effects of the RR tax would be more
difficult.

Nevertheless, one might still, after econometric estimation of

simul taneou

for both the regulated and unregulated transactions money

markets, be able to estimate partially the consequences of a RR tax; partially

Fifth, the first-cut characterization of the RR tax assumes everything
else remains constant. This assumption ignores the benefits the Fed derives
from relying on RR in effecting monetary policy. Specifically, through RR,
the Fed is capable of:

1) directly control 1 ing the money supply; 2)

preventing possible externalities attendant to bank failures resulting from
insufficient reserves; and 3) minimizing the relative impact of variabi 1 i ty in
excess reserves on the variability in the quantity of transactions money (and
thus on the income and price levels in the economy).

While changes in RR have

very rarely been used for the first reason and while Cagan (1979) argues that
the second reason is obviated by deposit insurance, an active federal funds
market, and the Federal Reserve as a lender of last resort, the third reason
does appear to be a possible justification for RR.

As Cagan points out, RR

make excess reserves "a smaller or more constant fraction of total reserves."
It is conceivable that the benefits of RR vis-i-vis excess reserves might be
measured by: 1) estimating the level of excess reserves that would prevail in
a non-RR world; 2) predicting the heightened variability in total reserves
that would result from the relatively higher level of excess reserves in the
non-RR world; 3) estimating the increased vari abi 1 i ty in national income and
prices that would result from the greater variabilty of total reserves; and 4)
comparing the costs of this variability with the allocative cost (i.e.,
deadweight loss) of a RR tax.
Finally, working from the first-cut approximation, it is also possible
to speculate about the effect of attempts to make the RR tax universal--to
meld the unregulated with the regulated sector in Figure 4. While more finely
ecified regulations may afford greater universality, it is doubtful whether
a11 of the unregulated sector may ever be transferred into the regulated
sector. Furthermore, if the RR tax is a burdensome one, transactions money

http://clevelandfed.org/research/workpaper/index.cfm

-

21

-

producers may be expected to vote with both their physical and mental feet
(they wi 1 1 devise ways of circumventing existing regulations and getting back
into the unregulated sector--e.g., RPs).

New firms will also be given the

incentive to enter the unregulated sector--firms that may be less susceptible
to the Fed (e.g., foreign banks) and that may create a product that is a much
more difficult form of transactions money to monitor and control (e.g.,
Merri 1 1 Lynch's parking-lot money).

5.

Transactions Money Price Floors
Regulations of the payment of interest on various forms of transactions

money are commonplace. There is, for example, a legal prohibition against
banKs paying any interest on demand deposits.

NOW accounts may only pay 5.25

percent.
Why are such interest rate ceilings actually price floors? The reason for
this apparent anomaly is rather simple. By limiting the amount of interest
that producers of transactions money may pay on certain forms of transactions
accounts, such regulations effectively dictate a user cost (i.e., a
transactions money price) to consumers of such transactions accounts.

The

level of this user cost will vary positively and monotonically with the market
rate of interest; i.e., the greater the interest rate, the higher will be the
user cost of the regulated transactions money (other things equal and provided
that tne interest-rate ceiling is effective).

The user cost of transactions

money likewise will vary negatively and monotonically with the level of the
tally proscribed interest-rate ceiling.

Assuming that both regulated and unregulated suppliers of transactions
money produce a homogeneous good (and thus that consumers/demanders of

http://clevelandfed.org/research/workpaper/index.cfm
Best available copy

- 22 transactions money cannot be differentiated along regulated market/unregulated
market 1 ines), the imposition of a nonuniversal interest-rate cei 1 ing on the
transactions money market may be depicted by Figure 10, where WBC represents
the supply of regulated transactions money before the imposition of the
interest-rate ceiling, ABC represents the supply of regulated transactions
money after the imposition of the interest-rate ceiling, PKJNO is the
aggregate supply of transactions money before the interest-rate ceiling
regulation, MLINO is the aggregate supply of transactions money after the
imposition of the interest-rate ceiling, and all other symbols are as before.
Note that the supply of regulated transactions money becomes horizontal at the
level of the user cost floor (this level will vary with the market rate of
interest and the interest-rate cei 1 ing)

.

regul ated

transactions money producers would be willing to supply their product at a
lower price than PItm to consumers, since the cost to the producers of
supplying their product falls below the user cost to consumers (i.e., the
price consumers wi 1 1 pay for the product)

.

Interest-rate cei 1 i ngs prevent

suppliers from doing so (exceptions to this are noted below), however, and
force consumers of such regulated goods onto the price floor AB.

After imposition of the interest-rate ceiling, the aggregate supply of
transactions money will be the horizontal sum of Stmu and ABC. The
aggregate supply of transactions money will thus be equal to Stmu below the
price of Pttm, have a horizontal segment at PItm, and be equal to the sum
Of

Stmu and ABC above the price of PItm.
The allocative consequences of an effective interest-rate ceiling (ceteris

1.

An increase in the price of transactions money from P*tm to PItm.

2.

A decrease in the aggregate quantity of transactions money
from Q* to Q'.

3.

An increase in the quantity of unregulated transactions money
from Q*tmu to Q'tmu*

4.

A decrease in the quantity of regulated transactions money
from Qktmr to Q1tmr. Note that Q1tmr = Q' - Q1tmu. The
quantity Qttmr will fall somewhere to the left of Q*tmr--its
exact location will be determined by the elasticity of Stmu. The
more elastic Stmu, the more will the quantity of regulated
transactions money decline following the imposition of an interestrate ceiling.

2.

A gain to producers of nonregulated transactions money equal
to area EFGH.

3.

A gain/loss to producers of regulated transactions money--depending
on whether area ARTS is greaterlsmaller than area TUV.
Analogous to the RR tax, the net wealth effect of an interest-rate

ceiling will be negative and will be equal in magnitude to area IJK--the
deadweight loss to the economy as a whole from an interest-rate ceiling.

http://clevelandfed.org/research/workpaper/index.cfm
Best available copy

An intermediate level approach allows several important observations and
hypotheses to be made about an interest-rate ceiling. First, such a price
floor toward consumers of transactions money provides another potential, if
only partial, explanation for the recent increase in unregulated transactions
money in the U.S. economy. The quantity of unregulated transactions money may
be expected to increase with a rising price floor--caused, for example, by a
rising market rate of interest.
Second, if the price floor becomes high enough (if segment AB moves up
sufficiently), regulated transactions money may be squeezed completely out of
the market--provided that the aggregate demand for transactions money, D,
intersects the aggregate supply at a quantity below the horizontal segment of
the aggregate supply curve.
Third, the higher the price floor for regulated transactions money, the
less control the Fed will have over transactions money; the more the quantity
of unregulated transactions money will increase and the more the quantity of
regulated transactions money will decrease. Thus, as market rates of interest
rise, one would anticipate that the Fed would have progressively less control
over transactions money (ceteris pari bus).

The greater the el asticity of the

supply of unregulated transactions money and the smaller the elasticity of the
supply of regulated transactions money (other things equal), the more quickly
the Fed's control over transactions money would erode.
Fourth, given that the cost of producing regulated transactions money is
less than the legally proscribed price for such money (below the quantity
Q "tmr ) ,

one would anticipate efforts on the part of regulated transactions

money producers to lower the user cost (i .e., price) of their product to
potential consumers. This argument might explain the payment of implicit
interest on certain types of regulated transactions money--implicit interest

http://clevelandfed.org/research/workpaper/index.cfm
Best available copy

in the form of free toasters, personalized checks.

Payment of such implicit

interest may be viewed as an attempt to compete away the rents (area ARTS)
that regulated producers derive from interest-rate ceilings. Payment of
implicit interest may also be characterized as an effort to "convexify" the
horizontal segment of the supply curve ABC--in the limit, an effort to get
back onto the supply curve WBC.
Fifth, while the RR tax may afford the Fed the benefit of minimizing the
effect of variable excess reserves, no similar potentially redeeming virtue
suggests itself in the case of interest rate ceilings. If anything,
transactions money price floors provide a "stableN and predictable source of
income for regulated suppliers that remain in the market. This stability is
eroded, however, both by the presence of unregulated producers and by the
payment of implicit interest by regulated producers. The higher the market
rate of interest (ceteris paribus), the greater the erosion. A stable source
of income for surviving regulated suppliers is also obtained at the expense of
both nonsurvivors and the Fed (the Fed's ability to control transactions money
is eroded).
Sixth, the regulated and unregulated sectors in the preceding analysis
of transactions money price floors need not correspond to the regulated and
unregulated sectors in the case of the RR tax.
Finally, the Intermediate Model approach to transactions money price
floors may easily incorporate a transformation/transportation cost element
(see Section 11.0.2. above).

B.2.

The Imperfect Substitutes Model
If regulated and unregulated transactions money are imperfect

substitutes (and non-transformabl e/non-transportable to the perfect

http://clevelandfed.org/research/workpaper/index.cfm
Best available copy

Figure 1 1

' tmr

substitutes case), a different analytic approach is necessary. Such an
approach will perhaps more clearly portray interest-rate ceilings as
transactions money price floors.
Suppose, for example, that there are two separate markets--one for

regulates transactions money and one for unregulated transactions money--as
shown in Figure 11, where Dtmr is the demand for regulated transactions
money, Dtmu is the demand for unregulated transactions money, EC is the
supply of regulated transactions money prior to the imposition of an interestrate ceiling, and all other symbols are as before.
Suppose that with the imposition of an interest-rate ceiling, consumers
of regulated transactions money are forced to pay a price (i.e., to bear a
user cost) of PItmr. Other things equal, the allocative effects of such a
price floor will include:
1.

A change in the effective supply curve of regulated transactions
money to P1tmrABC.

2.

A decrease in the quantity of regulated transactions money
from Q*tmr to Qttmr. Although the value of the marginal unit of
transactions money at quantity Qltmr exceeds the cost that must be

http://clevelandfed.org/research/workpaper/index.cfm
Best available copy

incurred to produce it, the price floor of Pgtmr precludes a
further expansion of regulated transactions money (since the
effective user cost exceeds the price consumers are wi 1 ling to pay).
3.

An excess supply of regulated transactions money at the price Pgtmr
of AB = QUtmr-QgtmU. This excess supply or the fact that the
cost of producing the marginal unit of transactions money exceeds the
price consumers are willing to pay for that unit at Qgtmr will
foster attempts on the part of regulated transactions money producers
to pay implicit interest--to stretch the effective supply
curve P1tmrABC toward the original supply curve EC.

4.

An outward shift in the demand for unregulated transactions money due
to the increase in price of a substitute good (regulated transactions
money).

5.

An inward shift in the supply of unregulated transactions money.

6.

An increase in the price and an uncertain effect on the quantity of
unregulated transactions money (due to the simultaneous shift in the
supply of and demand for unregulated transactions money).

7.

A deadweight loss in the regulated transactions money market equal to
area AFG.
While the distributive consequences of a price floor cannot be outlined

for the unregulated market, they may easily be delineated for the regulated
market:

1.

A loss to regulated transactions money consumers equal to
area P*tmrPitmrAG.

2.

A gain/loss to regulated producers--depending on whether
area P*tmrP'tmrAH is greater/smaller than area HGF.

3.

A negative net wealth effect equal to area AFH (a deadweight loss).

C. Innovations
Although innovations have occurred in both the regulated and unregulated
sectors of the transactions money market, the following examination will focus
on innovations in the unregulated sector. This approach is adopted for three
reasons. First, it appears that innovations in the transactions money market

.

ave occurred predominantly in the unregulated sector (e.g , money market

An outward s h i f t i n t h e s u p p l y of u n r e g u l a t e d t r a n s a c t i o n s money must

be d i s t i n g u i s h e d from an i n c r e a s e -i n t h e quantity supplied o f unregulated
t r a n s a c t i o n s money--the l a t t e r r e s u l t s from t h e i m p o s i t i o n o f e i t h e r a RR t a x

innovation, S ' is the aggregate supply of transactions money following an
innovation, and all other symbols are as before.
The allocative effects of an innovation include:
1.

A decrease in the price of transactions money from P*tm to P't,.

2.

An increase in the aggregate quantity of transactions money from Q*
to Q'.

3.

A decrease in the quantity of regulated transactions money
f ram Q*tmr to Q' tmr*

4.

An increase in the quantity of unregulated transactions money
from Q*tmu to Q1tmu. (The expansionary effect of the innovation
must outweigh the contractionary influence of a lower price--given
that the aggregate quantity increases, while the quantity of
regulated transactions money declines.)

5.

No deadweight loss.

The distributive effects of an innovation include:

1.
2.

A gain to consumers represented by area P*tmPItmGF.
A loss to producers of regulated transactions money equal to area

CEIH.
3.

A gain/loss to producers of unregulated transactions money--depending
on whether area MNLK exceeds/is exceeded by area ABKJ.

Note that innovations provide another possible explanation both for the recent
rapid increase in unregulated transactions money and for the simultaneous
decline in the Fed's ability to monitor and control transactions money.
Figure 12 also allows one to hypothesize that if an innovation is
extensive enough (if the supply curve of unregulated transactions money shifts
out far enough), regulated transactions money could be squeezed out of the
market altogether. This might happen, for example, if an innovation allowed
the bundling of money's store-of-value and medium-of-exchange attributes at
minimal cost. The squeezing out of regulated transactions money, however,
would occur only if the Fed had no ability to "capturen (e.g., via
legislation) new forms of unregulated transactions money.

CONCLUSION

While other aspects of the transact ions money market (e.g., subsidized
check-clearing processes, deposit insurance, and capital requirements) are
capable of being analyzed from a micro perspective, the preceding section has
focused on the comparative statics associated with only three central
aspects: reserve requirements, transactions money price floors (i nterest-rate
ceilings), and innovations. The analysis highlights the fact that a micro
approach may afford a better conceptual grasp of the transactions money market
than a macro approach. While much more empirical and theoretical work will be
required, the above-out1 i ned models are intended to generate interest in and
discussion about a perspective on the transactions money market that is "less
traveled by."

Such a micro perspective, at least as far as regulatory

decision making goes, might end up making ''all the difference."
