A BRIEF HISTORICAL OVERVIEW
While this chapter will not present a detailed history of monetary policy,
it is useful to first take a quick look at the evolution of thinking about
the nature of monetary policy. We will first examine the famous Currency
School-Banking School debates of the early 19th century, then turn to the
insightful analysis of Walter Bagehot. We next turn to the creation of the
Fed and early 20th century thinking about the role of the central bank.
The discovery of the "deposit multiplier" in the 1920s as well as the
developing understanding of open market operations had a very large
influence on the post-WWII theory of central bank control of the money
supply. While post-war "Keynesian" economists were skeptical of the
potency of monetary policy, the Monetarist approach gradually gained
adherents and came completely to dominate thinking about monetary policy
by the last quarter of the 20th century. However, Monetarism experienced
a quite remarkable turn-around of fortunes at the end of the century. As
we begin the 21st century, orthodox thinking about monetary policy is in
nearly complete disarray. However, there are themes that run through the
20th century and even the 19th century that offer some guidance in
reformulating and creating a truly institutionalist approach to monetary
policy.
Pre-War Monetary Policy
There are many similarities between the Currency School-Banking School
debate of the 19th century and the 1960s-1970s debate between Monetarists
and "Keynesians". (When I use the term "Keynesian" in quotes, I mean the
bastardized version of Keynes popularized by Samuelson and his followers,
and best exposited in the ISLM model. This is to be contrasted with
Keynes's own thoughts and those of his followers, the Post Keynesians.)
The debate centered around the relation between money and spending, on the
ability of the central bank (the Bank of England) to control the quantity
of money, and on the relation between the quantity of money and the
external balance. (Wray 1990) The Currency School tended to follow the
"Classical" view that an increase of the money supply would be fully
reflected in a rise of prices-in other words, they accepted what has come
to be known as the proposition that money is neutral. Further, because the
resulting inflation would make domestic output noncompetitive, this would
tend to cause a trade deficit. On a gold standard, this would then cause a
gold outflow, which would cause the money supply to decrease (as there
would be less gold to back it) and force prices to fall. Hence, the
"specie-flow" mechanism would tend to restore balance by automatically
reducing the supply of money.
If, however, some portion of the money supply were not backed directly by
gold, the specie-flow mechanism could not work because an outflow of gold
would not necessarily reduce the money supply. For example, if private
bank notes circulated as part of the money supply, but if these were not
strictly convertible to gold (or to government currency that was itself
strictly convertible to gold), an increased supply of private bank notes could
cause inflation and result in a persistent trade deficit. For this reason the
Currency School wanted to tightly constrain the issue of private bank notes by
requiring that private banks hold specie or Bank of England notes in an amount
equivalent to their private bank note issues. The Bank of England would be
able to control private money creation simply by controlling its own emission
of notes-which would serve as the required reserves of the private banks. In
short, like modern Monetarists, adherents to the Currency School approach
believed that "required reserves" would give to the central bank control over
that portion of the money supply that is privately created, and that this
would in turn allow the central bank to limit inflationary pressures that
would cause trade deficits. The Banking School, on the other hand, denied that
"excessive" creation of private bank notes is the cause of inflation. They
argued that bank notes are issued only on demand, and only because someone
wants to hold or spend them. Any excessive notes would be returned to banks
for redemption or to repay loans-what has been called the "law of reflux".
Indeed, the Banking School denied that private banks have any discretionary
influence over the quantity of bank notes outstanding-private money creation
is "endogenously" determined by the customers of banks. Further, central banks
could not affect the quantity of private notes issued, but rather would affect
only the terms on which they were offered in loans. In other words, central
bank policy operated not on the quantity of money but rather on the interest
rate-restrictive policy would increase interest rates.
Note, however, that the Banking School argued that the law of reflux would not
apply to a government-issued "fiat" money that was not convertible. As it was
not redeemable for gold, a government fiat money could be issued in excess
without refluxing back to government. Hence, a government fiat money could
indeed be excessive and could thereby contribute to inflation-and could cause
a trade deficit. However, as privately issued money would reflux to the
issuers, so long as it was redeemable, it could not directly affect inflation
or the trade balance. Like some modern day "Keynesians", the Banking School
saw monetary policy as operating indirectly, only through its affects on
interest rates. Thomas Tooke, the foremost Banking School theorist argued that
"(I)t is only through the rate of interest and the state of credit, that the
Bank of England can exercise a direct influence on the foreign exchanges...."
(Tooke 1959, p. 124) According to Tooke, proper monetary policy would not
worry about the quantity of money but instead would attempt to stabilize
interest rates: "[T]he greater or less liability to variation in the rate of
interest constitutes, in the next degree only to the preservation of the
convertibility of the paper and the solvency of banks, the most important
consideration in the regulation of our banking system." (ibid)
Unfortunately, as is often the case, the persuasiveness of the position of the
Banking School was lost on policy makers. Parliament adopted the Currency
School principles in its Act of 1844, which tried to limit private bank note
issue by placing a ceiling on their issue and by constraining Bank of England
note issuance. Tooke's analysis some years later was harsh:
As the result of a careful examination of the principle on which the Act of
1844 was founded, and of the experience of its working since the time when it
came into operation, I have no hesitation in giving it as my opinion that it
is a total, unmitigated, uncompensated, and, in its consequences, a lamentable
failure. (Tooke 1848, vol IV, p. 402)
The variations, in the rate of interest, during the year 1847, have exceeded
in frequency and extent any of which there is to be found an example in the
commercial history of this country. (Tooke 1848, vol IV, p. 400)
As we'll see later, one could say much the same of the Federal Reserve's
application of Monetarist principles in the early 1980s.
Over time, England developed what we might call a "mono-reserve" system in
which private banks promised to redeem their own liabilities (initially
taking the form of bank notes, but eventually mostly taking the form of
deposits) for Bank of England notes. Private banks thus held some Bank of
England notes in vaults, but most of their reserves took the form of
deposits in key London banks, which in turn held deposits on the Bank of
England. In a sense, the whole banking system "pyramided" reserves on the
Bank of England, which gave it tremendous power in determining interest
rates. It could cause "tight money" by calling in advances made to London
banks or brokers, or it could raise the interest rate required in its
discount of bills, or it could simply refuse to discount bills altogether.
When faced with tight money, London banks would call in overdrafts and
force correspondent country banks to sell consols or stock. This tended to
cause bond prices to fall and interest rates to rise. (Sayers 1957, pp. 125-7;
Wray 1990, p. 51) In this way, the Bank of England could affect market
interest rates. When England ran a trade deficit, the Bank of England would
face an external drain of specie. It would then institute a tight money regime
to attract bullion inflows seeking higher interest rates. However, an external
drain would often generate an internal drain: bank customers might notice a
drain on bank reserves, become worried over the stability of banks, and hence
try to obtain loans and discount bills before credit was cut off. Worse, they
would try to withdraw deposits or redeem notes. This would lead to a further
(internal) drain of reserves of the Bank of England, which would tighten money
even further to stem the drain. A panic would result whenever the Bank of
England acted like it might not provide the reserves needed by the private
banks. Indeed, the Bank of England would frequently sell securities to
replenish its own reserves-simply adding pressure on private banks.
By the last quarter of the 19th century, Bagehot forcefully argued that
this was precisely the wrong policy. (Bagehot 1927) He believed that one
of the most important functions of a central bank is to act as a lender of
last resort. He recognized that in any mono-reserve system, the monopoly
supplier of that reserve must supply reserves without limit whenever the
banking system faces a panic. The way to stop a run on reserves is to
demonstrate to the public that private bank liabilities can be, and will
be, redeemed on demand for the ultimate reserve. This would restore
confidence and stop bank runs. Note that Bagehot's recommendation is
consistent with the Banking School's preference for policy to aim at
interest rate stabilization, while the Bank of England's actual policy
only caused interest rates to rise even further during a panic.
Bagehot's influential book was published in 1873, and his recommendations
were gradually incorporated within the dominant view of economic
theorists. By the end of the 19th century, the Bank of England endorsed
Bagehot's theory in its policy. When the Fed was established in 1913, one
of the principal justifications for its creation was the recognition that
the panic of 1907 might have been prevented or at least attenuated if a
national lender of last resort had been in existence. In a mono-reserve
system based on liabilities of the central bank, reserves can always be
expanded without limit as the central bank lends reserves (at the discount
window, by discounting eligible "bills"), or provides them through open
market purchases of assets. Hence, the Federal Reserve Act of 1913 charged
the Fed with furnishing "an elastic currency" and "the means of
rediscounting commercial paper". (Meulendyke 1989, p. 18) For many years
thereafter, the guiding principle of the Fed was the 'Real Bills Doctrine'
under which the Fed was to rediscount eligible paper (thus make loans of
reserves to member banks) on demand to meet the needs of trade.
(Meulendyke 1989).
The original Act did not provide for open market operations. Since WWII in
the US, we have become accustomed to central bank open market
operations-purchases and sales of government debt-and to the impact these
have on banking system reserves. However, before WWII, the outstanding
stock of government debt was generally not large (except following wars),
and banks typically got their reserves at the discount window by
submitting eligible paper for discount. WWI had also increased the supply
of government debt, and just like private banks, the Fed had purchased
some of this debt as an interest-earning asset. It was not until the 1920s
that the effect of open market operations by the central bank was
generally understood. It was also at this time that the 'deposit
multiplier' was discovered: an open market purchase would create reserves
that were believed to permit a multiple expansion of deposits. (Meulendyke
1989) While some commentators at the time noticed that an open market
operation that increased/decreased bank reserves would simply lead to
offsetting activity at the discount window (as discounts fell/rose), this
recognition was gradually lost as Currency School-type thinking was
revived after WWII in a particularly virulent, Monetarist, form.
Monetary policy during the Great Depression has received a bad rap. Some
have faulted the Fed for "allowing" half of all banks to fail. If the Fed
was created in 1913 to save banks facing a run, why did it stand by as
bank after bank had to close its doors? A simple, but not complete, answer
is that the Fed saw as its mandate the charge to lend reserves to
otherwise solvent banks. In other words, the Fed was supposed to provide
liquidity by discounting "good" bills, but was not supposed to save banks
whose bills (and other assets) were questionable. The banks that were
failing were not merely illiquid, they were also insolvent because their
assets had collapsed in value. The far less valid, but nearly universal,
complaint about the Fed, however, is the absurd Monetarist claim that the
Fed reduced the money supply, and, hence, caused the bank failures. This
view has been popularized by Friedman and Schwartz (1963), who claim that
tight monetary policy by the Fed turned a downturn into a long depression.
As evidence, they point out that the money supply and bank reserves
declined during the depression; since they believe that the Fed determines
the quantity of money through the deposit multiplier and its control over
bank reserves, the Fed deserves the blame.
Actually, the Fed intervened immediately and forcefully in 1929, buying
$125 million of Treasury securities the day of the stock market crash,
five times the maximum weekly amount it was authorized to purchase, and
doubling Fed holdings in one day. (Muelendyke 1989; Wray 1998, p. 99)
However, as the asset price deflation spread, and as the depression forced
down production and prices of goods and services, defaults on loans
snowballed throughout the economy. In this environment, banks were forced
to default on their own commitments (the demand and savings deposits of
their customers) and/or reduce their loan portfolios (due to lack of good
borrowers). Hence, the money supply fell because of the depression and it
is rather silly to claim that the depression could have been avoided if
only the money supply had continued to grow rapidly. (There is only one
sense in which Friedman and Schwartz are correct in claiming that tight
money policy contributed to the depression. Until the US went off the gold
standard, the Fed did indeed worry about loss of its gold reserves if
there were a run on US dollar-denominated assets. Hence, the Fed's
interest rate policy was constrained because the US interest rates could
not drop significantly below those of other countries-ignoring
expectations of exchange rate movements-without draining gold. Thus, if a
lower interest rate might have had a marginal, positive, influence on
borrowing and spending, then one could argue that monetary policy should
have been "looser". However, this was not possible so long as the dollar
was redeemable for gold.)
Post-War Policy
During WWII, federal government deficits reached to nearly a quarter of
GDP, leading to large issues of treasury debt. The Fed agreed in 1942 to
peg the three-month Treasury bill rate at 3/8 of one percent to keep
government interest costs low; longer-term bonds were informally pegged at
somewhat higher rates. In effect, the T-bill rate operated as a floor for
interest rates, and by keeping it low this tended to keep interest rates
on private debt low (at a markup over the rate paid by government, with
the differential determined largely by default risk and capital risk).
After the war, the Fed was concerned with the potential for inflation and
wanted to abandon the peg so that it would be free to raise rates to fight
inflation. In 1947 the Treasury agreed to loosen the reigns on the Fed,
which raised interest rates. The Fed continued to lobby for greater
freedom to pursue activist monetary policy, resulting in the 1951 Accord
in which the Fed abandoned its commitment to maintain low interest costs
for the government. Henceforth, the Fed would manipulate the interest rate
to implement countercyclical monetary policy.
After the War, banks were flush with government debt. Gradually, the Fed's
emphasis moved from the discount window to open market operations. During
the 1950s, the fed funds market was created and evolved to become the
primary private "market" for excess reserves. Before the development of
the fed funds market, a bank needing reserves would sell government bonds;
banks with excess reserves would buy government bonds to obtain earning
assets. The fed funds market allowed surplus banks to lend reserves
directly to deficit banks, often requiring that borrowing banks put up
government bonds as collateral. The fed funds rate gradually became the
key short-term, base, interest rate.
After the 1951 Accord, the Fed-for political reasons-did not announce
interest rate targets. Its newly won independence required that it
proclaim that it was not pegging rates. However, it is clear that the Fed
was targeting Treasury bill rates until the mid 1960s, when it switched to
a fed funds target because the fed funds market had by then become the
primary means for reserve adjustment by individual banks. Any aggregate
deficit of reserves would immediately place pressure on the fed funds
rate, inducing Fed provision of reserves to keep the rate from rising
above target. Not only did the fed funds rate serve as an almost immediate
indicator of reserve positions, but a fed funds target did not have the
political baggage that accompanied a bills rate target (which determined
the government's cost of issuing debt). Of course, the two rates would be
inextricably linked, but it was politically easier for the Fed to increase
the fed funds rate than it would be to explicitly raise government
interest costs. Over the post war period, the Fed also began to rely on
repurchase agreements and reverse repos rather than on outright open
market purchases and sales in order more finely to tune market
conditions.
The discovery of the reserve effects of open market operations and the
discovery of the deposit multiplier, together with the growing
post-depression consensus that government "ought" to try to use monetary
and fiscal policy in a countercyclical manner, led to the belief that the
Fed should try to increase the growth of the money supply in a downturn
and reduce its growth in a boom. To be sure, economists were not unanimous
in their belief that this would do much good. The typical "Keynesian"
believed that while monetary policy might be fairly effective in a boom
(tight money policy could slow money growth and hence slow growth of
spending), it probably would have little effect in a recession. It was
said that one "cannot push on a string"-the Fed would not be able to
encourage loan-making activity and thereby increase the money supply if no
one wanted to spend. Hence, most economists believed that in a recession,
fiscal policy would be more effective in stimulating demand.
The notion that a central bank can influence reserve and monetary
aggregates had been around for quite some time, as indicated above,
however, the Fed did not adopt formal monetary targets until 1970, with
the express purpose of bringing down inflation by reducing money growth.
Still, during most of the 1970s, the Fed explicitly adopted the fed funds
rate as the operating target used to hit intermediate (monetary
aggregates) targets. If the rate of growth of the money supply were above
the Fed's target, it would raise the fed funds rate target. Unfortunately,
the 1970s saw "stagflation" so the Fed was continually in
inflation-fighting mode. In October 1979, the new Chairman, Paul Volcker,
announced a major change of policy: the Fed would henceforth use the
growth rate of M1 as its intermediate target, with reserves as the
operating target, while it would allow the fed funds rate to rise as high
as necessary to allow achievement of this goal. (Fazzari and Minsky 1984)
The Fed would calculate the total reserves consistent with its money
target, then subtract existing borrowed reserves to obtain a non-borrowed
reserve operating target. However, in practice, when the Fed did not
provide sufficient reserves in open market operations (as it hit its
non-borrowed reserve target), banks would simply turn to the discount
window, causing borrowed reserves to rise (and, in turn, causing the Fed
to miss its total reserve target). Because required reserves are always
calculated with a lag (see Moore 1984 and Wray 1998), the Fed could not
refuse to provide required reserves at the discount window, thus, it found
it could not control total reserves. Further, the rate of growth of M1
exploded beyond targets in spite of consistently high interest rates that
resulted from the Fed's tight policy (the fed funds rate reached above 19%
during April 1980 and hit 20% in January 1981). So the Fed found it could
hit neither its reserve nor its M1 targets. The attempt to target
nonborrowed reserves ended in 1982 while the attempt to hit M1 targets was
abandoned in 1986. (Meulendyke 1989; Fazzari and Minsky 1984) Still, the Fed
continued to announce and tried without success to hit M2 targets during the
rest of the 1980s. The attempt to target growth of monetary aggregates finally
came to an official end in 1993 after more than a decade of miserable failure.
The fate of Monetarist doctrine in academic circles nearly mirrors its fate in
policy-making. Over the course of the 1960s and 1970s, Monetarism gradually
rose in favor, from virtual obscurity to accepted doctrine. As "Keynesianism"
lost its following in the 1970s-largely due to stagflation-use of fiscal
policy to tame the business cycle lost credence. Hence, in the 1980s,
Monetarism, rejection of fiscal policy, and exclusive use of monetary policy
in a countercyclical manner became increasingly accepted among academicians.
By the mid 1980s, it would not have been far wrong to claim that academic
macroeconomists were all Monetarists. At the end of the decade, however,
Monetarist doctrine was in question because the Monetarist experiment at
controlling the money supply had been such a disaster in the US (and also in
the UK). (Ben Friedman 1988) That is a remarkably quick turn-around for
accepted doctrine.
Both theorists and policy makers quickly abandonedthe belief that the Fed
could control the money supply and that the money supply determines the rate
of spending and thus of inflation. Paradoxically, a "cult of Greenspan" (the
BOG chairman who had replaced Volcker in 1987) developed in the US and abroad.
While no one could put into words exactly how he single-handedly whipped
inflation and created a "Goldilocks" economy (neither too hot to cause
inflation nor too cold to cause unemployment) in the last half of the 1990s,
virtually all analysts came to believe that the Fed somehow is responsible for
not only keeping inflation in check, but also for keeping real GDP growth at
potential. The Greenspan-led Fed became so bold as to announce immediately
after each FOMC meeting exactly what the fed funds rate target would
be-something the Fed had never before done. The financial press deconstructed
every word uttered by Chairman Greenspan in the 1990s, trying to anticipate
the Fed's next action. Whether he hinted that inflation was around some corner
or other, or that the stock market suffered from "irrational exuberance", or
that the "New Economy" offered rapid productivity growth as far as the eye
could see, every Greenspan speech moved financial markets. The Greenspan Fed
changed interest rate targets frequently-first up to fight invisible but
incipient inflation, then down to forestall a slump. Every quarter-point
change of the fed funds rate target was supposed to have a monumentally
important impact on production, prices, and employment. Every improvement of
the unemployment rate and every downward click of inflation was proof positive
of Greenspan's guiding hand. While Al Gore was said to have claimed to have
invented the internet, everyone knew that Al Greenspan had suckled and
nurtured NASDAQ and the New Economy. His efforts did not go unrewarded: he was
reverently treated in Bob Woodward's Maestro (the title says it all); and he
won the highly valued "Enron Prize", funded by a high-tech energy speculation
firm that went bust during the Fall of 2001 in the most spectacular and
expensive bankruptcy in US history-at just about the precise moment that
Greenspan had lost his luster.
While Greenspan's fall from grace has not, yet, been quite so impressive
as that of NASDAQ and Enron, and while it has lagged the demise of
Monetarist doctrine, it may well be as complete by the time this volume
hits the streets. As of late winter 2002, the stock market has fallen
significantly and is poised for collapse; the Goldilocks New Economy is
long dead, dead, and gone; every component of Greenspan's highly touted IT
sector is reeling; unemployment is rising faster than at any time since
the Great Depression; household net wealth has fallen-for the first time
ever in US history; and the private sector is suffering under record debt
levels as bank customers default, as bank profits fall, and as we move
down the path to massive and widespread bank insolvency. The Fed has
lowered interest rates a dozen times, or so-to no avail. No doubt
Greenspan feels like the guest who has overstayed his welcome and regrets
the fact that he did not retire with his saintly wings intact in 2000 and
thereby avoid the fall from Maestro to dot-com sucker in a matter of
months. His speeches are now but an irrelevant embarrassment, having no
measurable impact on financial markets. The most articulate and inflation
hawkish of the Fed's governors, Larry Meyer, has refused to serve another
term-preferring the relatively certain and carefree life of a private
economic forecaster over serving as a member of a thoroughly discredited
Fed BOG.
IS THERE AN ALTERNATIVE APPROACH TO MONEY?
Where to begin? Institutionalists reject the entire orthodox corpus,
including the view of money advanced, the pseudo history adopted, the
theory of the role that money plays in the economy, and orthodox policy
analysis and prescription. In the orthodox story, money comes out of
markets, created by barterers to reduce transactions costs. Above all a
handy medium of exchange, money plays no essential role in orthodox
theory-our economy would function in substantially the same manner even if
we were to ban money from the system and return to barter. Indeed, modern
technology should allow barter-based markets to function without entailing
many transactions costs of the sort that money's creation was supposed to
have eliminated. At most, orthodox economists debate about the conditions
under which money might have some short-run non-neutrality; in the long
run, according to orthodoxy, money's neutrality is assured. Finally, as
discussed above, most mainstream theoretical approaches presume that money
is under control of the "monetary authorities"-in theory, if not in
practice. Only Austrians and Real Business Cycle Theory aficionados deviate
from this "exogenous" money approach, although Austrians do so in order to
imagine a utopia of "free" banks without an evil government or central bank,
while RBC theorists do so in order to make money "super-duper" neutral.
Neither fringe approach warrants further inquiry.
In contrast, most heterodox economists, including institutionalists, adopt an
"endogenous" money approach similar to the views of the Banking School
examined above. Privately issued money (mostly bank deposits today) is issued
only on demand, that is, only because someone has deposited cash or is willing
to take out a loan. The latter activity has been concisely described by Post
Keynesians as "loans make deposits" because when a bank accepts a borrower's
IOU it simultaneously creates a bank deposit. The idea that privately created
money could be "excessive" is ludicrous, for as the Banking School explained,
any excess would "reflux" to banks. Those with "extra" bank deposits would
retire loans, withdraw cash, or buy something (the latter of which just shifts
the deposits about; the first two activities reduce bank deposits in the
aggregate). It is literally impossible for banks to force excess money onto
the economy because there must be willing borrowers in order for banks to
create deposits.
The second important point made by Post Keynesians is that "deposits make
reserves", reversing the interpretation of the deposit multiplier. They
emphasize that reserves cannot be a discretionary variable from the point of
view of the central bank. There are a number of reasons for this. Many,
including Basil Moore (1988), have argued that because required reserves (in
those nations that have them) are always calculated with some lag, based upon
deposits that are "history" (issued by banks at some point in the past), banks
cannot adjust deposits to cope with a position of insufficient reserves to
meet requirements. This means that only reserves can be adjusted-so that a
bank caught short will turn to the fed funds market. However, if the system as
a whole is short, at least one bank will not be able to meet requirements. In
practice, central banks always and automatically lend reserves to such banks,
booking a shortfall as an overdraft or loan of reserves. If they did not, they
would force the bank to fail to meet legal mandates. Further, if the central
bank did not provide desired reserves, banks with insufficient reserve levels
would bid the fed funds rate above target. (Note that the reverse is also
true: if the system as a whole has excessive reserves, the fed funds rate is
bid below target-at the limit it will fall nearly to zero.) Hence, an orderly
fed funds market requires that the central bank provide/drain reserves to
eliminate deficiencies or surpluses.
In addition, timely and orderly check clearing among banks requires that the
Fed automatically provide reserves as required. Banks use reserves for net
clearing of checks (recall the discussion of a mono-reserve system). If the
Fed refused to routinely make up for aggregate reserve shortfalls, the
payments system could not operate smoothly. Indeed, if the Fed stopped lending
reserves as needed, checks would bounce. If a bank was suspected of nearing a
position of a shortage of reserves, other banks would refuse to accept its
checks. It is because the Fed always credits reserves to the account of a
receiving bank without first ensuring that the bank upon which a check is
drawn has sufficient reserves that bank checks always clear at par. Indeed,
this was a primary purpose of the creation of the Federal Reserve System,
before which bank notes commonly circulated below par. Finally, payments to
the Treasury by bank customers (tax payments, mostly) are also made using bank
reserves. Imagine the problems that would be created if a taxpayer's check to
the IRS bounced because her bank did not have sufficient reserves! Again, in
practice the Fed always provides reserves to banks as needed to meet reserve
requirements, to clear checks among banks, and to make payments by check to
the Treasury.
If the central bank cannot control reserves in a discretionary manner, and if
the deposit multiplier is reversed, and if the supply of privately created
money is essentially determined by the demand for loans, then what can the
central bank control? Leaving aside regulatory and supervisory issues for the
moment, the central bank only has one policy tool: the overnight interbank
lending rate, or fed funds rate (called the bank rate in the UK). This rate
can be hit with a great degree of accuracy, indeed, as mentioned above the
Greenspan Fed began to simply announce what the target would be, and the fed
funds rate would nearly instantly move toward the target. All the Fed must do
to keep the actual rate at the target is to ensure that banks have the
quantity of reserves they require or desire; if the rate rises above/falls
below the target, the Fed adds/drains reserves until the rate aligns with the
target. While some at the Fed would like for us to believe it is all very
complicated and hence that it requires teams of highly trained economists to
provide detailed analyses and forecasts of future demand for reserves, that is
mostly obfuscation to protect budgets, jobs, and the Fed's reputation.
Turning to the "nature" and "origins" of money, institutionalists reject the
orthodox notion that money is essentially a commodity that functions primarily
as a medium of exchange, invented to reduce transactions costs.
Institutionalists and other heterodox economists insist that money is "social"
in its nature. As Ingham puts it "money necessarily consists in social
relations between economic agents and between them and a monetary
'authority'...." (Ingham 2000, p. 19) Or, as Neale argues: "all monies are
parts of larger systems of economic and social relationships." (Neale 1976, p.
4). Further, Neale warns that "Despite the fact that many a text on money says
that money originated in the inconvencies of barter, that money was invented
as a medium of exchange....neither historical evidence nor argument by analogy
from contemporary nonliterate societies lends support to this speculative
history." (Neale 1976, pp. 8-9)
Admittedly, any story of the origins of money is necessarily speculative for
two reasons. First, we must decide what "social relation" from the past
qualifies as something we are willing to label "money". Neale argues that it
is best to think of "monies" rather than "money" because those social
relations vary widely by society. He emphasizes that in most pre-capitalist
societies the range of social relations associated with use of a "special
purpose money" was much narrower than those we now associate with "general
purpose money". For example, we would now likely include medium of exchange,
unit of account, means of debt settlement, and store of value as functions
that are served today by general purpose money. However, in previous societies
(and in nonliterate societies today) there have been "special purpose monies"
that served only one or two of these functions but not the others. The second
problem is that it is possible and even likely that the origins of money lie
in a very distant past for which we have no easily interpretable records;
indeed, many believe that money predates writing. (It has long been believed
that writing was invented to keep track of nominal debts, although the history
of writing is probably as complex as the history of money. See
Schmandt-Besserat 1989.) Hence we will probably never have a completely
satisfying story of the origins of money.
Still, it is tempting to speculate on money's origins. There are three
plausible alternatives to the orthodox story. Heinsohn and Steiger (1983)
argue that money developed not out of a barter economy but when private
property and loans developed. Following Keynes, they emphasize that early
monetary units were based on a specific number of grains of wheat or barley.
(Keynes 1982, pp. 233-36) Later, metals (such as iron, copper, silver, or
gold) were used as money, with the value denominated in those grain units of
measurement. According to their argument, the first money was created when
private property (so many units of grain) was loaned with the expectation of
payment of a greater sum of grain in the future. Eventually, grains of wheat
or barley would be used as a universal equivalent to measure value of all
types of alienable private property to reduce transactions costs, acting as a
unit of account in all creditor-debtor relations. Gradually, representative
money, in the form of metal but still denominated in these grain weight units,
could be loaned, used as a medium of exchange, and used to settle debts.
Hence, Heinsohn and Steiger focus on money as a unit of account developed in
these early loan agreements, and the "thing" used as money is important
primarily because it represents the loan agreement that is denominated in the
unit of account.
A second approach has been advanced by Hudson (2001), who has developed an
alternative thesis for the origins of the money of account in Babylonia. He
argues that money originated within the temple and palace communities for
internal accounting purposes. Like Heinsohn and Steiger, his story also
emphasizes the importance of loans, however, he argues that early loans were
made by the temple and palace communities to the "external" sector. Thus,
rather than focusing on private property and loans between individuals that
gradually become standardized in a grain unit of account, Hudson believes the
unit of account was created within the early bureaucracies. Clearly, his
argument focuses more on the social nature of the origins of money and hence
is probably more appealing to institutionalists.
A third approach has been developed by the great numismatist, Grierson, and
elaborated in Goodhart (1989, 1998) and Wray (1998). According to this view,
money evolved out of the pre-civilized practice of wergeld; or to put it more
simply, money originated not from a pre-money market system but rather from
the penal system. (Grierson 1977, 1979; Goodhart 1998) An elaborate system of
fines for transgressions was developed in tribal society. Over time,
authorities transformed this system of fines paid to victims for crimes to a
system that generated a variety of payments to the state. (Innes 1932) Until
recently, fines made up a large part of the revenues of all states. (Maddox
1769) Gradually, fees and taxes as well as rents and interest were added to
the list of payments that had to be made to authority. To be clear, this
authority should be seen as a gradually evolving institution-from early
temples to palace communities to feudal kings and finally to democratically
elected representative governments-with varying degrees of sovereign power.
All that was required was some sort of authority able to levy obligations on a
population--anything from fines or tithes to fees and taxes. While wergeld
payments did not require a unit of account (the fines were assessed in the
form of particular items or services to be delivered to victims), payments to
the authority were gradually standardized, measured in a money of
account.
This approach has been called the "Chartalist" or "taxes-drive-money"
approach. It is also closely related to Knapp's "state money" approach.
Briefly, this view emphasizes the important role played by "government" in the
origins and evolution of money. More specifically, it is believed that the
state (or any other authority able to impose an obligation--whether that
authority is autocratic, democratic, or divine) imposes an obligation in the
form of a generalized, social unit of account--a money--used for measuring the
obligation. The next important step consists of movement from a specific
obligation--say, an hour of labor or a spring lamb that must be delivered--to
a generalized, money, obligation. This does not require the pre-existence of
markets, and, indeed, almost certainly predates them. Once the authorities can
levy such an obligation, they can then name exactly what can be delivered to
fulfill this obligation. They do this by denominating those things that can be
delivered, in other words, by pricing them. To do this, they must first
"define" or "name" the unit of account. This resolves the conundrum faced by
methodological individualists and emphasizes the social nature of money and
markets. Note that the state can choose anything it likes to function
as the "money thing" denominated in the money of account, and, as Knapp
emphasized, can change "the thing" any time it likes: "Validity by
proclamation is not bound to any material" and the material can be changed to
any other so long as the state announces a conversion rate (say, so many
grains of gold for so many ounces of silver). (Knapp 1924, p. 30) What Knapp
called the State money stage begins when the state chooses the unit of account
and names the thing that it accepts in payment of obligations to itself-at the
nominal value it assigns to the thing. The final step occurs when the state
actually issues the money-thing it accepts. In (almost) all modern developed
nations, the state accepts the currency issued by the treasury (in the US,
coins), plus notes issued by the central bank (Federal Reserve notes-green
paper-in the US), plus bank reserves (again, liabilities of the central
bank)-that is, the monetary base or high powered money (HPM). The material
from which the money thing issued by the state is produced is not important
(whether it is a gold coin, a base metal coin, paper notes, or even numbers on
a computer tape at the central bank). No matter what it is made of, the state
must announce the nominal value of the money thing it has issued (that is to
say, the value at which the money-thing is accepted in meeting obligations to
the state).
Many orthodox economists are "metallists" (as Goodhart 1998 calls them), who
argue that until this century, the value of money was determined by the gold
used in producing coins or by the gold that backed up paper notes. However, in
spite of the amount of ink spilled about the gold standard, it was actually in
place for only a relatively brief instant. Typically, the money-thing issued
by the authorities was not gold-money nor was there any promise to convert the
money-thing to gold (or any other valuable commodity). Indeed, throughout most
of Europe's history, the money-thing issued by the state was the hazelwood
tally stick. Other money-things included clay tablets, leather and base metal
coins, and paper certificates. Why would the population accept otherwise
"worthless" sticks, clay, base metal, leather, or paper? Because the state
agreed to accept the same "worthless" items in payment of obligations to the
state. Contrary to orthodox thinking, then, the value of the money-thing
issued by the state was not determined by its intrinsic value, but rather by
the nominal value set by the state at its own pay offices (at which it
accepted payment of fees, fines, and taxes).
In the orthodox story, barter is replaced by use of a medium of exchange; due
to its inherent characteristics, barterers soon settle on gold (or another
precious metal) as the most efficient medium of exchange. In order to reduce
transactions costs involved in assessing purity and weight, this metal is
stamped and coined. However, it has long been established that the first coins
were issued in Lydia and East Greece, probably no earlier than the third or
fourth quarter of the seventh century BC, and long after other forms of
complex financial instruments, local markets, and long distance trade had been
established. If precious metal coins were indeed invented to reduce
transactions costs, one wonders why it took so long to discover them. Further,
while coins might have been important to the Greek world and perhaps to the
Roman world, they played a relatively unimportant role throughout most of
European history. Numismatists, such as Kraay (1964) have challenged the
economistic thinking of orthodoxy by arguing that coins were invented to
standardize payments made by and to the state.
In a detailed study of the origins of coinage in Greece during the seventh
century BC, Kurke (1999) links the creation of coins to "a seventh/sixth
century crisis of justice and unfair distribution of property", that was
eventually decided in favor a democratically-leaning city state against a
hostile elite. (Kurke 1999 p. 13) In her view, "the minting of coin would
represent the state's assertion of its ultimate authority to constitute and
regulate value in all the spheres in which general-purpose money operated
simultaneously-economic, social, political, and religious. Thus, state-issued
coinage as a universal equivalent, like the civic agora in which it
circulated, symbolized the merger in a single token or site of many different
domains of value, all under the final authority of the city." (Kurke 1999, p.
13) By tying the invention of coinage to the special circumstances of Greece
during that period, Kurke's analysis makes it clear why coins were so
unimportant to other societies, before and since. Further, as Kurke makes
clear, since coins are nothing more than tokens of the city's authority, they
could have been produced from any material. The choice of gold should be
viewed as something of a coincidence, resulting from the particular hierarchy
of metals in elite gift exchange extant in Greece at that time. In other
words, and in contrast to the orthodox story, there is nothing inherent in
gold (or silver, or copper) that guarantees its adoption as the money thing. A
state is theoretically free to name anything it wants, although the historical
circumstances might dictate that one thing is preferred over others.
Once the state has created the unit of account and named that which can be
delivered to fulfill obligations to the state, it has generated the necessary
pre-conditions for development of markets. All the evidence suggests that in
the earliest stages the authorities provided a full price list, setting prices
for each of the most important products and services. Once prices in money
were established, it was a short leap to creation of markets. This stands
orthodoxy on its head, by reversing the order: first money and prices, then
markets and money-things (rather than barter-based markets and relative
prices, and then numeraire money and nominal prices). The next step was the
recognition by government that it did not have to rely on the mix of goods and
services provided by taxpayers, but could issue the money-thing to purchase
the mix it desired, then receive the same money thing in the tax payments by
subjects/citizens. This would further the development of markets because those
with tax liabilities but without the goods and services government wished to
buy would have to produce for market to obtain the means of paying obligations
to the state. As Heinsohn and Steiger (1983) say, the market is the place to
which one turns for earning the means of debt settlement, including the means
of tax settlement. This is quite different from the orthodox view that markets
develop so that individuals may maximize utility by trading
consumables.
The final theoretical topic to be tackled concerns money's supposed
neutrality. The discussion thus far should make it clear that money cannot be
neutral, as it is not simply a medium of exchange invented to lubricate market
exchange. If, as I have hypothesized, money originated as a means to move
resources to the public or state sector, then it clearly had a "real" impact.
If, as Heinsohn and Steiger speculate, money was invented in private loan
contracts, it played a crucial role in an important social relationship-that
between debtor and creditor. Further, if one views the market as a place for
earning the means of settling debts (both private debts and tax debts), rather
than as a place to which one turns to increase utility through mutually
beneficial trades, then one sees the market as a fundamentally monetized
institution. Regardless of the origins of money and markets, institutionalists
have always distinguished between the technical aspects of production and the
pecuniary considerations involved in producing for markets. In the modern
capitalist economy, the primary purpose of production is not to exchange for
other consumables, but to "make money"-that is, to sell at a profit. The most
famous characterization of capitalist production is Marx's M-C-M', according
to which the capitalist begins with money (M) to produce commodities (C) to
sell for more money (M'). Keynes advanced what he called the "monetary theory
of production", emphasizing the same point; Dillard (1988) explicitly adopted
Keynes's terminology, as have many institutionalists. (See also Mayhew 19xx
and Wray 1993.) If modern production begins and ends with money, money cannot
be neutral. Indeed, rather than arguing that money is a veil that hides "real"
activity (as Friedman does), one might more accurately argue that money is the
"real" variable that motivates production while the "real" output that results
is just a veil that obscures the true purpose of individual decision making of
capitalist production.
AN ALTERNATIVE VIEW OF FISCAL AND MONETARY POLICY
In the orthodox approach, the government must tax, borrow, or "print money" in
order to spend. If the government borrows, that is likely to place upward
pressure on interest rates, "crowding out" investment. If it prints money,
that is likely to generate inflation. While most economists do not insist that
government continuously balance its budget, limiting its spending to its tax
revenue, they do believe that a perpetual deficit is to be avoided. Not only
would it cause interest rates or inflation to rise (depending on whether the
deficit were financed by borrowing or money creation), it could also
eventually cause government insolvency and default on its obligations. During
the last two decades of the twentieth century, "fiscal discipline" was
increasingly imposed in most developed nations and in many developing nations
(especially those that had fallen under the control of the IMF and World
Bank). Indeed, several developed nations (including Japan, the US, Canada, the
UK, and Australia) actually ran significant surpluses in some years during the
final decade of the century. This was almost universally cheered by
economists, as an antidote to the budget deficits that had been common in the
post war years.
Institutionalists have always rejected such notions. They have always taken
the pragmatic approach perhaps best espoused in Lerner's functional finance
approach: "The central idea is that government fiscal policy, its spending and
taxing, its borrowing and repayment of loans, its issue of new money, and its
withdrawal of money, shall all be undertaken with an eye only to the results
of these actions on the economy and not to any established traditional
doctrine about what is sound or unsound." (Lerner 1943, p. 39) Further,
institutionalists have recognized that the notion that government borrowing
"crowds out" private borrowing is really based on either the loanable funds
argument or on the supposition that the supply of money is fixed. Foster
(1981) was among the first to recognize how revolutionary was Keynes's
argument that investment creates an equivalent amount of saving; similarly, a
government deficit must also create an equivalent amont of saving. Hence, a
government deficit cannot absorb saving that would otherwise have gone to
finance investment. Further, given the endogenous money arguments provided
above, it is clear that government borrowing could not reduce the amount of
"money" available for firms to borrow from banks. Banks create money when they
make loans, and no amount of government deficit spending would reduce bank
ability to create deposits for firms to use to finance investment.
These are powerful arguments, even if they appear rather simple. However, they
can be strengthened by adding the Chartalist or taxes-drive-money approach.
When a modern government spends, it issues a check drawn on the treasury; its
liabilities increase by the amount of the expenditure and its assets increase
(in the case of a purchase of a good produced by the private sector) or some
other liabilities are reduced (in the case of a social transfer). The
recipient of the check will almost certainly cash it at a bank, in which case
either the recipient will withdraw currency, or (more likely) the recipient's
bank account will be credited. In the former case, the bank's reserves are
first increased and then are reduced by the same amount. In the latter case,
bank reserves are credited by the Fed in the amount of the increase of the
deposit account. The bank reserves carried on the books as the bank's asset
and as the Fed's liability are nothing less than a claim on government-issued
money, or, a leveraging of HPM. In other words, treasury spending by check
really is the equivalent of "printing money" in the sense that it increases
the supply of HPM. Unless bank required reserves happened to increase by an
equivalent amount, the banking system will typically find itself with excess
reserves after the treasury has spent, creating HPM.
The important thing to notice is that the treasury can spend before and
without regard to either previous receipt of taxes or prior bond sales. In the
US, taxes are received throughout the year (although not uniformly as tax
payments are concentrated around April 15 and other quarterly due dates).
These are mostly paid into special tax accounts held at private commercial
banks. (Bell 2000) It is true that the Treasury transfers funds from these
private bank accounts to its account at the Fed when it wishes to spend, but
this is really a reserve maintenance operation designed to minimize effects on
reserves that result when the treasury issues checks. When the treasury
spends, bank reserves increase by approximately the same amount (less only
cash withdrawals) so that the simultaneous transfer from tax accounts is used
to neutralize bank reserves. These additions to/subtractions from reserves are
carefully monitored and regulated by coordination between the Fed and the
treasury, but this should not confuse analysts about the processes at work.
The Treasury spends by having the Fed emit HPM; that HPM is simply a liability
that can be increased at will. The treasury does not need to transfer deposits
from private banks to the Fed in order to spend; it needs to do so
simultaneously with spending only to minimize reserve effects.
On the other hand, tax payments by households lead to a reserve drain as the
treasury submits the checks to the Fed for clearing, at which point the Fed
debits the bank's reserves. Things would be much simpler and more transparent
if tax receipts and treasury spending were perfectly synchronized. In that
case, the treasury's spending would increase reserves, and the tax payments
would reduce them. If the government ran a balanced budget there would be no
net impact on reserves. In this case there would be no need for the complex
coordination between the Fed and treasury using tax and loan accounts because
there would be no reserve effects so long as the budget were balanced.
However, let us suppose that the timing were synchronized but that spending
exceeded tax revenues so that a budget deficit resulted. This means that after
all is said and done, there has been a net injection of reserves. It is
possible that the extra reserves created happen to coincide with growing bank
demand for reserves-in which case the Treasury and Fed need do nothing more.
More probably, the net injection of reserves resulting from budget deficits
would lead to excess reserves for the banking system as a whole. The receiving
banks would offer them in the fed funds market, but would find no takers. This
would cause the fed funds rate to begin to fall below the Fed's target,
inducing the Fed to drain reserves either through an open market sale or by
reducing its discounts. When the treasury runs a sustained deficit, quarter
after quarter and year after year, the Fed would find it was continually
intervening to sell bonds; obviously, it would eventually run out of bonds to
sell. This is why, over the longer run, responsibility for bond sales designed
to drain excess reserves from the system must fall to the treasury-which faces
no limit to its own sales of bonds as it can create new bonds as
needed.
While it may sound strange, we conclude that Treasury bond sales are not a
borrowing operation at all, but are in fact nothing but a reserve draining
operation. This becomes apparent when one recognizes that the Treasury cannot
really sell bonds unless banks already have excess reserves, or unless the Fed
stands by ready to provide reserves the banks will need to buy the bonds. If
the Treasury typically tried to first "borrow" by selling bonds before it
spent, it would be trying to drain reserves it will create only once it
spends. As it drained required or desired reserves, it would cause the fed
funds rate to rise above the Fed's target-inducing an open market purchase and
injection of reserves by the Fed.
Another way of putting it is that the government spends by issuing IOUs, and
the private sector uses those IOUs to pay taxes and buy government bonds.
Obviously, if government spending were the only source of these IOUs, the
private sector could not pay taxes or buy bonds before the government provided
them through its spending. In the real world, government spending is the main,
but not the only source, of the IOUs needed by the private sector to pay taxes
and buy government bonds. In addition, the central bank provides its IOUs
through discounts or open market operations, and these IOUs are perfect
substitutes for treasury IOUs. Unfortunately, most economists have become
confused about all this because they do not understand the nature of the
coordination between the Fed and the Treasury.
Indeed, most economists do not understand that monetary policy has nothing to
do with the quantity of money, but is concerned only with the overnight
interest rate. The central bank's provision of, or removal of, reserves is
nondiscretionary and is always merely in response to actions of the treasury
or the private sector. On the other hand, fiscal operations always impact
reserves, and government deficits always lead to a net injection of reserves.
Boulding came close to capturing this when he said: It's just
as true as it is funny, That Deficits increase our money; In
understanding this there lies The power of States to Stabilize.
(Boulding 1958, p. 183) The purpose of government bond sales is
not to borrow reserves -- a liability of the government-but is instead
designed to offer an interest-earning alternative to undesired
non-interest-earning bank reserves that would otherwise drive the fed funds
rate toward zero. Note that if the Fed paid interest on excess reserves, the
Treasury would never need to sell bonds because the overnight interest rate
could never fall below the rate paid by the Fed on excess reserves. Note also
that in spite of the widespread, orthodox, belief that government deficit
spending places upward pressure on interest rates, it would actually cause the
overnight rate to fall to zero if the treasury and Fed did not coordinate
efforts to drain the created excess reserves from the system. (For proof of
this, note that for many years after the mid 1990s, the overnight interest
rate in Japan was kept at zero, in spite of government deficits that reached
8% of GDP, merely by keeping some excess reserves in the banking system.) On
the other hand, budget surpluses drain reserves from the system, causing a
shortage that would drive up the fed funds rate if the Fed and Treasury did
not coordinate actions to buy and/or retire government debt. Needless to say,
orthodoxy has got the interest rate effects of government budgets exactly
backwards.
One could think of government bonds as nothing more than HPM that pays
interest-indeed, as described above, the government would never need to sell
bonds if the Fed paid interest on excess bank reserves, or if the Fed's
interest rate target were zero. Bond sales are not really a borrowing
operation but are instead an interest rate maintenance operation. Obviously,
however, banks are not the only entities in the private sector that would like
to earn interest by holding government IOUs. Indeed, households and firms
generally like to accumulate a portion of their net wealth in the form of
interest-earning government debt. In a growing economy, the outstanding stock
of government IOUs (both interest-earning and non-interest earning) will need
to grow to keep pace with the demands of the private sector. This means that a
government deficit should be the "normal", expected, situation. In contrast,
sustained budget surpluses can be achieved only by draining the government
IOUs held as net wealth. This is why government budget surpluses usually
cannot be sustained for long-they reduce the private sector's disposable
income (because taxes exceed government spending) and destroy private net
wealth (by draining government IOUs), and hence set off tremendous
deflationary impacts on the economy.
MONETARY POLICY RECOMMENDATIONS
The main monetary policy recommendation that follows from this analysis is
that central banks should abandon any pretense that they can influence the
quantity of reserves or the quantity of money privately created. They should
admit that they only set the overnight interest rate-the fed funds rate in the
US. This of course sets the base interest rate; short-term interest rates on
government debt are determined rather directly by the fed funds rate because
the banking system uses this market as a substitute for the fed funds market
to adjust reserves at the individual bank level. Longer-term government debt
is priced more complexly because it must include potential capital gains and
losses that result from future changes to the fed funds rate target. When a
central bank frequently changes its targets wildly-as the Fed has increasingly
done since the mid 1960s-a great deal of uncertainty about future policy must
be built into the pricing of longer term assets. Indeed, this is the primary
reason that markets deconstructed every word uttered by Chairman Greenspan
during the 1990s, trying to anticipate policy moves that would impact asset
prices.
It is very difficult to see why a great deal of uncertainty about Fed interest
targets is desirable. Wild swings of asset prices tend to reinforce
uncertainty and encourage speculative behavior. As Keynes argued, "Speculators
may do no harm as bubbles on a steady stream of enterprise. But the position
is serious when enterprise becomes the bubble on a whirlpool of speculation.
When the capital development of a country becomes a by-product of the
activities of a casino, the job is likely to be ill-done." (Keynes 1964, p.
159) An "active" Fed that continually tries to surprise markets with interest
rate adjustments promotes the casinos over enterprise. As Tooke argued in the
quote above, "[T]he greater or less liability to variation in the rate of
interest constitutes, in the next degree only to the preservation of the
convertibility of the paper and the solvency of banks, the most important
consideration in the regulation of our banking system." (Tooke 1959, p. 124)
As the Fed's propensity to destabilize the interest rate has increased since
the mid 1960s, speculative behavior has increased and economic performance has
suffered. Obviously, other factors have also contributed to this and we cannot
say with certainty that greater instability of interest rates has been the
decisive factor.
The orthodox response is that the Fed must move interest rates
countercyclically in order to help to fine-tune the economy-to fight inflation
in booms and lower unemployment in recessions-hence, even if this contributes
to greater instability of asset prices, the Fed cannot abandon its
responsibility. There are, however, strong reasons to doubt that Fed policy
has much impact on either unemployment or inflation. As discussed above, low
interest rate policy in a slump does not seem to have much effect on
spending-for fairly obvious reasons, consumers are reluctant to borrow when
they fear losing their jobs, and firms are unlikely to invest as sales are
falling.
Furthermore, the interest rate is really a redistributive variable, as for
every interest payment there is an interest receipt. When the Fed lowers
interest rates this does indeed benefit new borrowers and anyone with existing
debt that can be reset at a lower rate. However, all those who rely on
interest payments for income (particularly pensioners and financial
institutions) suffer as rates fall. Interest income has increased greatly in
the postwar period as the population has aged, and as workers have built up
pension funds and other savings for their retirement years. The conventional
argument is that interest payments represent a transfer from mostly low and
middle income earners to the rich, hence, lower interest rates redistribute
income from those with a low marginal propensity to consume toward those with
a high propensity to consume. There is surprisingly little work on this,
however. With the aging of western societies, the redistribution that results
today from rising interest rates is probably mostly from firms and younger
workers (especially from new homeowners with mortgages) toward elderly
persons. It is not clear that this necessarily reduces the overall propensity
to consume. More importantly, in a modern economy with a large outstanding
stock of government debt, the redistribution is largely from government to
households and firms. Indeed, if the stock of government debt were large
relative to national income and to private debt, it is possible that lower
interest rates actually depress spending because of the effect on private
sector incomes as government interest payments fall. It is conceivable that
Japan reached such a situation in the late 1990s, when short term interest
rates effectively reached zero.
Can central banks stabilize the overnight interest rate? Yes, so long as they
do not try to peg currency exchange rates. Recall from the discussion above
that during the Great Depression the Fed worried that if it kept interest
rates too low, the US would lose reserves of gold. Exchange rates are fixed on
a gold standard and hence only adjustments of the interest rate could stem a
"run" on dollar-denominated assets. In the modern world, countries do not
operate on a gold standard, and most countries have adopted floating exchange
rates. Hence, if the US were to keep interest rates lower than those abroad,
it is possible that from time to time there might be downward pressure on the
dollar. So long as the US allows the dollar to fall, it can maintain low
interest rates without losing international reserves. Note that low interest
rates do not necessarily cause currency depreciation-Japan's currency has
remained exceedingly strong (many would say it was overvalued) even with
overnight rates at zero. Exchange rates, like long term interest rates, are
complexly determined and the overnight interest rate is only one factor that
goes into their determination. However, in any event, so long as exchange
rates are indeed flexible, a nation's overnight interest rate is "exogenous"
and can be set anywhere the central bank wants to put it.
What else should a central bank do? We have dealt with the issues that are
most closely related to orthodox views on monetary policy: reserves, money
aggregates, inflation, and interest rates. In addition, we have addressed
Bagehot's recommendation that the central bank must operate as a lender of
last resort--still among the most important functions of the central bank.
There is also a wide array of other important central bank functions:
Setting required reserve ratios: While orthodox economists believe
that required reserve ratios give the central bank leverage over private money
creation, we have seen this is false. Others believe that maintenance of
reserves makes banks safer because they hold a liquid asset. However, if a
central bank stands ready to discount eligible assets, a bank does not need to
hold reserves for liquid purposes. Indeed, it could be argued that required
reserves in excess of the level of reserves that would be held voluntarily for
clearing purposes acts like a tax on banks (forcing them to hold assets that
do not earn a return). If this lowers bank profitability it could actually
reduce bank safety and soundness. The UK has never had legal reserve ratios;
Canada has recently moved to a system in which the required reserve ratio is
zero. On balance, there is probably little argument in favor of retaining
legal requirements, and in practice, legal ratios in the US are now so low
that they probably are not very binding especially given all the innovations
banks use to reduce requirements (such as sweep accounts).
Finally, as discussed above, government spending creates bank reserves, and
reserve requirements force banks to hold nonearning reserves rather than
earning government bonds. Hence, one might conclude that reserve requirements
lower government "borrowing" costs (a point frequently made by populist groups
such as COMER in Canada). However, the government can have any "borrowing"
cost it wants, including zero, merely by setting the fed funds rate target at
that level. It seems a bit strange to argue that banks, alone, should earn
zero if the government has decided that everyone else can earn a positive
return by holding government liabilities. Alternatively, as discussed above,
the Fed could pay interest on reserves-in which case the difference between
bank reserves and treasury bills disappears. Equivalently, the Fed could allow
banks to count interest-earning government liabilities as reserves to meet
requirements.
Credit Controls: Many support use of the Fed to try to channel credit
to some areas, and to discourage it from others. Some have argued for
asset-based reserve requirements to discourage banks from holding some kinds
of assets. For example, if the Fed wanted to encourage home mortgage loans but
discourage commercial real estate loans, it could require reserves against the
latter, but exclude home mortgages from reserve requirements. The same sort of
result can be obtained by risk-weighting assets and requiring greater net
equity ratios against riskier assets (as is done with the Basle Accord), or
simply by imposing a tax on bank purchases of riskier assets. All such
requirements work by reducing the relative return on unfavored assets. Others
have emphasized that central banks can impose margin requirements on
borrowers, requiring them to put up liquid assets as collateral-raising the
cost of borrowing. In the US, the Fed has the authority to change margin
requirements on stock purchases, so that buyers are constrained in the percent
of borrowed funds they may use to purchase stocks. During the NASDAQ boom
after the mid 1990s, the Fed refused to raise margin requirements, although
some believe this would have constrained the boom.
Encourage provision of financial services: Relatedly, many American
analysts want to use the Fed and other monetary authorities (including other
regulatory agencies such as the FDIC, the Comptroller of the Currency, and
state banking regulators) to encourage an increased supply of credit to areas
thought to be underserved. Most importantly, some studies have shown that
financial institutions have traditionally discriminated against certain groups
(racial minorities, women) and have "red-lined" some neighborhoods (drawn a
"red line" around neighborhoods to which they would not provide many services,
including loans). Note that redlining is not exactly the same as
discrimination-while red-lined areas typically were neighborhoods with a high
proportion of minority residents, even white males living in them would be
denied banking services simply because they lived in red-lined areas. The
Community Reinvestment Act in the US forced banks to report on the services
provided in their own self-defined business area, and many analysts believe
this has played an important role in reducing discrimination and red-lining
activity. In addition, it has often been believed that more credit needed to
be supplied to finance certain activities deemed to have significant social
worth. This led to creation of Government Sponsored Enterprises (essentially
institutional arrangements that put government guarantees behind loans
initiated by private lenders) that have targeted lending to favored groups
such as homeowners (Fannie Mae), students (Sallie Mae), farmers (Freddie Mac),
and veterans. (Stanton 1991)
Supervision and regulation: Many economists have argued that bank
regulation and supervision is a necessary corollary to central bank lender of
last resort activity as well as to implicit and explicit government guarantees
(such as those offered through FDIC and the Government Sponsored Enterprises).
If government intervenes to prevent or contain failures, then adverse
incentives are created. While all modern, developed, economies regulate and
supervise financial institutions, the US is fairly unusual in the degree to
which responsibilities are shared by the Fed, the FDIC (and in the past, the
now-defunct FSLIC), the FHLBB, the Comptroller, and state regulators. There
have been sensible proposals to streamline and consolidate these activities in
the US, but they have never made much headway. Part of the problem is that
financial institutions have been very important campaign contributors, and
seats on House and Senate committees that have anything to do with financial
institutions are highly prized as campaign cash cows. Since the early 1970s,
most changes to supervision and regulation have been free-market-oriented,
designed to unleash "entrepreneurial initiative". The most notorious example
is the series of legislative maneuvers that succeeded in "freeing" US savings
and loans associations to "market forces", playing a significant role in
creating the thrift crisis of the 1980s that required a massive government
bail-out. (Wray 1998) More recently, the Glass-Steagall Act (that had
separated commercial banking from investment banking since the Great
Depression) was eroded, first for the biggest financial institutions, allowing
commercial banks to become involved in equities markets. As this chapter is
being written, the deregulation chickens are coming home to roost as the Enron
fiasco spreads to Enron's partner banks, including J.P. Morgan and Citi-Group.
It is also becoming apparent that the mostly self-regulated accounting firms
played an important role in hiding Enron's financial mis-dealings, just as
they had done in the Saving and Loan fiasco a dozen years earlier. Unregulated
markets seem to do well when they are doing well, and remarkably poorly when
the offal hits the fan. It is too soon to forecast how this will all play out,
but a very serious and prolonged recession is likely to contribute to such a
financial mess that there will be a sea-change of policy, away from
laissez-faire and back toward New Deal-era sorts of reforms.
