FUNCTIONAL FINANCE AND US GOVERNMENT BUDGET SURPLUSES IN THE NEW MILLENNIUM�

In
this chapter, we will explore the nature of �government finance�. The
approach presented here is properly called a �functional finance� approach
to government finance�an antidote to conventional principles of �sound
finance�. Readers will recognize the debt owed to Abba Lerner; indeed, some
functional finance principles were incorporated into Keynesian
economics�bastard and otherwise�but I believe the full import of
Lerner�s principles of functional finance has not been recognized even by
followers of� Keynes. An
understanding of the nature of government finance not only sheds light on
�fiscal policy�, but also on the true nature of what is normally called
�monetary policy�. We will then move on to analysis of US government
budget surpluses at the beginning of the new millenium, and of projections
that these will continue into the twenty-first century as the government
retires its outstanding debt stock.

BRIEF
OVERVIEW OF CONVENTIONAL VIEWS ON GOVERNMENT FINANCE
According
to the conventional view, tax
revenue provides the income needed by the government to finance its spending.
A government might be able to spend in excess of its revenue, at least
temporarily, if it is able to issue debt that the public will hold. That is,
the government might be able to borrow
from the public to finance deficit spending. One method that is almost
universally scorned is for the government to issue non-interest-bearing debt
� currency � to finance deficits. This can either be done directly by the
Treasury, or indirectly through the central bank. Because government deficits
financed in this manner would directly cause the money supply to expand, many
economists claim this would directly cause inflation.
�����������
If, instead, the government sold interest-earning bonds to finance (or
�fund�[i])
its deficit, the money supply would increase � according to most economists
� only if the central bank �accommodated� by increasing bank reserves.
So long as the central bank did not accommodate, there should be no direct
impact on inflation.[ii]
However, government borrowing is likely, according to a common view, to
�crowd out� private borrowing because government borrowing adds to the
demand for loanable funds, driving up interest rates, and displacing
interest-sensitive private spending (presumably, investment, housing, and
consumer durables). Crowding out can be partial, complete, or even more than
complete, depending on assumptions.[iii] Over the longer run, if
crowding out does occur, this will depress aggregate supply and could thereby
induce cost-push inflation.
�����������
Finally, while most economists recognize that at least under some
situations government deficits are desirable (and that at times, benefits
outweigh costs), most would argue that persistent deficits must be avoided.
Even Keynesian[iv]
economists generally argue that structural deficits should be avoided; that
is, while a government should run deficits in recessions, these should be
offset by surpluses during expansions. It is believed that permanent deficits
must be avoided because no government can operate in such a manner as to
generate the expectation that it will never be able to retire its debt, that
is, the expectation that debt can only be �rolled over�. While there may
not be a specific debt-to-GDP or deficit-to-GDP ratio at which markets lose
trust in the government, it is not doubted that such thresholds exist.[v]
Governments are thus believed to be subject to market forces that determine
the quantity of debt the government can issue as well as the price (interest
rate) of the debt. If the domestic population will not take up all the debt,
the government is forced to sell bonds in international markets. International
markets might even force the government to borrow in a foreign currency (issue
foreign-currency-denominated debt) if the country�s finances are
questionable. Indeed, the government may be forced to impose austerity on its
population in order to placate international markets before it will be able to
sell bonds internationally.
�����������
The principles of �sound finance� can also be applied to portions
of the government�s budget, representing individual programs such as the
Social Security program. Since 1983, �sound finance� has meant running
large and rising OASDI (Old-Age and Survivors Insurance) surpluses in order to
�advance fund� baby-boomer retirements. The reasoning behind this will be
familiar to all readers: the number of retirees per worker will rise rapidly
early this century, making it impossible to cover (rising) OASDI benefit
payments from payroll taxes (without raising them to exorbitant levels). (Papadimitriou
and Wray 1999) Thus, surpluses are necessary today in order to �save� and
thereby reduce the burden on future workers. Many analysts have (belatedly)
recognized some of the peculiarities of trying to keep separate accounts for a
portion of the government�s budget.� For
example, some controversies have centered around the practice of
�accumulating� Social Security surpluses in the form of Treasury debt.
Those holding up the troglodyte end of the debate argue that when it comes
time for babyboomer retirements, the Treasury might just default on the debt,
thus, favor �investing� Social Security surpluses in a broader range
of�presumably more credit-worthy�private assets. The more astute argue
that when the time comes, the Treasury will either have to raise other
(non-payroll) taxes, borrow, or �print money� to retire the IOUs held by
the Social Security Trust Fund. Thus, some (including Friedman 1999) have
argued that the Trust Fund is nothing more than an �accounting gimmick�
that allows the government to �owe itself�.
�Keynesians�
(Blinder 1999, Summers and Yellin 1999) have defended current practice,
arguing that to the extent that Social Security can run large surpluses, this
can offset deficits in the rest of the government�s budget. Indeed, because
of the extraordinary turn-around achieved during the Clinton boom, the overall
budget has moved to surplus allowing retirement of some publicly held debt. So
far, the surplus is entirely attributable to the Social Security program, but
on current projections the rest of the budget will move to surplus soon.
Indeed, surpluses are now projected as far as the eye can see, which leads
�Keynesians� to argue that the government�s budget is contributing to
national saving and thereby lowering interest rates and stimulating private
investment. (Blinder 1999) This will then generate faster economic growth and
thereby lessen the �real burden� on future workers of providing for the
elderly. Thus, running Social Security surpluses is �sound finance� that
adds to expected surpluses on the rest of the budget. While the normal
�Keynesian� position would be that there is nothing necessarily wrong with
running cyclical budget deficits so long as budgets are structurally balanced,
the �excesses� of the Reagan-Bush deficits justifies structural surpluses
over the intermediate term. This is butressed by the new-found faith in the
ability of Saint Greenspan�s Fed to offset the depressionary impact of
budget surpluses (in spite of the oft-repeated warning that one cannot �push
on a string�, as well as the glaring example of the Japanese quagmire),
which has led� Blinder and Summers
to support structural budget surpluses�at least through the first two
decades of the new millennium.�

BUDGETS
AND ACCOUNTING CONVENTION
Let
us turn to a more fundamental question: why is it important to balance
budgets? If an economic unit cannot �spend� by issuing its own IOUs, its
spending is limited by its stock of readily accepted medium of exchange and
flow of income received in the form of the medium of exchange. We might call
this a liquidity constraint. Clearly, most economic units are not strictly
limited by liquidity constraints because they are able to incur liabilities as
they spend. Sometimes this takes the simple form of postponed payment�for
example, allowing �payment� thirty days after delivery of a good or
service�which is the implicit acceptance by the seller of a short-term
liability. Other times, a financial intermediary is involved, allowing a
seller to receive immediate payment in the form of the medium of exchange
while a buyer is committed to deferred payment of principal and interest to
the intermediary. Of course, variations on these themes lead to complex
financial instruments and financial commitments. Minsky (1986) created a
tripartite division to describe financial positions: hedge to denote an
economic unit whose income flows meet committed outflows in every period;
speculative to identify a unit that could meet only interest payments out of
income flows over at least some of the contract period; and Ponzi to indicate
a unit that would have to �capitalize� interest�that is, increase
liabilities just to make interest payments.
Note
that there is no �deep� economic constraint on ability to spend by
incurring liabilities�if one can �borrow� to pay interest (Ponzi
finance), there is no strict limit to the amount of debt that one can
service�even if one had no income at all. Recognition of this simple point
has long bothered economists, leading to Smith�s admonition that banks must
require repayment of loans by delivery of banknotes rather than
�fictitious� bills of exchange[vi],
as well as to the �real bills doctrine� (which would limit expansion of
bank lending to �self-liquidating� debts).
Modern
economists have tended to resolve this issue by looking at long-run
sustainability, often defined as a situation in which the debt-to-income ratio
is not permitted to rise beyond some limit. However, it should be clear that
such a constraint is of necessity arbitrary�rules of thumb, accounting
rules, or regulatory limits that establish constraints on the ability of an
economic unit to issue debt�and because these limits are a human invention,
they can be finessed and changed. This is not to argue that such rules are not
reasonable. For example, one might reasonably argue that an economic unit with
a finite life span should be expected to retire liabilities before, or at, the
time of death, unless liabilities can be forced onto heirs. However, there is
no �deep� reason why even the dead could not continue to service debt
through Ponzi finance. In any case, economic units with potentially unlimited
lifetimes, such as governments or corporations, do not face this problem, but
one could pick from among a number of reasonable constraints that might be
imposed�such as a limit to the portion of income flows that ought to be
devoted to debt service. Let us emphasize that such a constraint, while
reasonable, would be chosen arbitrarily.
When
we turn to the case of a sovereign nation, which has the right to issue
currency, it is not so easy to determine what is an income flow. Most would
identify tax revenues as the appropriate accounting equivalent to a
nongovernmental income flow. However, it has long been recognized that
governments obtain seigniorage income if they can issue currency whose nominal
value exceeds its cost of production. Even in the case of a gold standard, it
is supposed that government typically obtained seigniorage either by charging
for minting precious metals brought to the mint or by debasing coin. Clearly,
in the modern economy with a �fiat� money, the cost of issuing currency
falls close to zero. This means that �printing money� is an alternative to
�tax revenue� as an income source, and because the direct costs to
government are nearly zero �seigniorage� generates an unlimited income so
long as the fiat money is accepted.
Orthodoxy
posits a limit to the public�s acceptance of government currency��money
demand� is not infinite except under special circumstances (the liquidity
trap). Beyond some point, it is argued, the government might have to issue
interest-paying bonds, �borrowing� money rather than issuing it. This
commits government to paying interest, thus, bond issue could lead to a Ponzi
finance situation if tax revenues plus money emission become insufficient to
pay interest on the outstanding debt stock (requiring government to issue
bonds just to raise the �money� required to pay interest). As discussed
above, this does not in itself lead to a necessary constraint on government
spending. Rather, most analysts would argue that it is the economic effect on
the economy that places a limit on the prudent level of deficits or growth of
deficits or level of debt or debt ratio.[vii]
Such impacts could include effects on prices or interest rates.
In
the next section, we turn to an alternative view of �government
accounting�, before returning to current debates about the government
surplus.

GOVERNMENT
BUDGETS AND FIAT MONEY
Abba
Lerner presented a functional finance approach as an alternative to the
doctrine of sound finance. He argued
������������
Functional Finance rejects completely the traditional doctrines of
�sound finance� and the principle of trying to balance the budget over a
solar year or any other arbitrary period. In their place it prescribes: first,
the adjustment of total spending (by everybody in the economy, including the
government) in order to eliminate both unemployment and inflation, using
government spending when total spending is too low and taxation when total
spending is too high; second, the adjustment of public holdings of money and
of government bonds, by government borrowing or debt repayment, in order to
achieve the rate of interest which results in the most desirable level of
investment; and third, the printing, hoarding or destruction of money as
needed for carrying out the first two parts of the program. (Ibid. p. 41)
�We
will argue that his approach can be applied to all modern economies in which
the government provides the domestic currency. Our discussion that follows
cannot, however, be applied to any country that adopts an external
currency�for example, one that operates a currency board. Governments of
such economies are not able to issue a fiat money.
�����������
Virtually all modern capitalist economies operate on the basis of a
high powered money (HPM) system[viii]. The HPM is issued
directly by the Treasury (as in the US, where the Treasury issues coins or
checks) or through the central bank (as in the US, where the Fed issues paper
notes and issues reserves whenever banks present Treasury liabilities for
payment) as a non-convertible government (Treasury) or quasi-government
(central bank) liability. This HPM generally functions as legal tender, that
is, it is sanctioned by the courts as the money which fulfils �all debts,
public and private�. It is the only money that is ultimately accepted in
payment of taxes.[ix] It is also the money into
which bank liabilities are convertible (either on demand or after some
specified waiting period), and which is used for ultimate (or net) clearing
among banks and between private banks and the central bank. It is the money
used as the link between the public and private pay communities.[x]
It is the money that sits at the top of the debt pyramid (or hierarchy), or
the �definitive� and �valuta� money.[xi]
It is the most liquid liability used domestically � except in rare
circumstances where a foreign currency is used domestically (as is the case in
some of the formerly socialist countries today). The most important thing to
understand is that in a normally functioning modern economy, the domestic HPM
is always accepted in exchange for domestic production; anything that is for
sale with a dollar price can be had by delivering US currency (coins or
notes).[xii]
�����������
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) or some other liabilities are
reduced (in the case of a social transfer, for example, Social Security
benefit liabilities are reduced by the amount of Social Security checks
issued). The recipient of the Treasury check will almost certainly �cash�
the check at a bank; either the recipient will withdraw currency, or, more
commonly, the recipient�s bank account will be credited. In the latter case,
bank reserves are credited by the Fed in the amount of the increase of the
deposit account. For our purposes, it is not important to distinguish between
the Fed�s and the Treasury�s balance sheet. The bank reserves carried on
books as the bank�s asset and as the Fed�s liability are nothing less than
a claim on HPM � at any time, the bank can convert these to coins or paper
notes, or use them in payments to the government. When the recipient
�cashes� a Treasury check, a bank will convert reserves to currency �
which is always supplied on demand by the Fed, which acts as the Treasury�s
�bank�, converting one kind of Treasury liability (a check written to the
public) to another kind (coins or an IOU to the Fed, offset by Fed issuance of
paper notes).
�����������
The important thing to notice is that the Treasury spends 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 receipts
are concentrated around certain quarterly dates, as well as the 15 April
deadline) mainly into special tax accounts held at private commercial banks.
It is true that the Treasury transfers funds from the private banks to its
account at the Fed when it wishes to �spend�, but this is really a reserve
maintenance operation. When the Treasury spends, bank reserves increase by the
same amount (unless cash is withdrawn from banks) so that the transfer from
tax accounts is used to stabilize bank reserves. If the Treasury did not make
this transfer, its spending would lead to an increase of bank excess reserves,
which would have to be drained by the Fed. Thus, if the Treasury attempts to
transfer funds more-or-less in step with its spending, this reduces the size
of interventions required of the Fed. These additions to/subtractions from
reserves need to be carefully monitored, with a central bank injection of
reserves used to make up any shortfall (for example, if transfers from tax
accounts exceed deposits of Treasury checks) or a reserve drain used to remove
excess reserves.
�����������
These central bank actions are taken to offset the daily fluctuations
that destabilize the overnight interest rate (called operating factors). By
consolidating the Fed and Treasury balance sheets, one sees that in reality,
the Treasury cannot withdraw taxes from the economy before spending � any
transfer of tax accounts from the private economy to the government�s
balance sheet would have to be exactly offset by government provision of an
equivalent amount of HPM through use of the Fed�s balance sheet. In
practice, a tax payment to the Treasury leads to debit of a commercial bank
reserve account. If that bank has insufficient reserve balances at the Fed, it
incurs an overdraft that is booked as a loan of reserves from the Fed to the
bank. Thus, HPM is restored automatically whenever the Treasury accepts tax
payments that lead to insufficient reserve positions. Indeed, this is
necessitated by �par clearing��if bank checks always clear at par in
payments made to the Treasury, then HPM must be provided as needed to the
banking system to ensure there is HPM available for clearing purposes.
�����������
In any case, as government is the only supplier of HPM, it cannot
receive in taxes HPM that it has not provided to private markets. The original
source of all HPM must be the (consolidated, Fed plus Treasury) government,
and the coordination between the Treasury and central bank is required to
maintain reserves. If it were not for the effect of government spending on
bank reserves, there would be no need to tie spending to transfers from tax
accounts. The coincident timing of tax �receipts� and government spending
(or central bank open market operations) is not an indication of a
�financing� operation but rather is required to maintain stability in the
market for reserves. The implication is that tax payments do not �finance�
government spending but that they must serve another purpose. (See Bell 1998,
Mosler 1997-8,� and Wray 1998, Chapter 5 for further exposition.)
�����������
In principle, then, the government first spends HPM (to purchase goods,
services, and assets or to provide �transfer payments�, which retires a
government liability). Once the government has spent, then that HPM is
available to be transferred to the government to meet tax liabilities. As a
matter of logic, the public cannot pay HPM to the government to meet tax
liabilities until the government has paid out HPM to the public. In a modern
capitalist economy, it may appear more complex than this because most taxes
are paid using checks drawn on bank deposits, rather than currency. However,
this amounts to the same thing since every payment of taxes generates a
reserve clearing drain, or, a loss of reserves.[xiii] Thus taxes cannot be
paid until actual coins or notes are injected into the economy, or bank
reserves have been created. Government expenditure will generate coins, notes
or bank reserves that are needed to �pay taxes�. It is also true that
central bank �lending� (purchases of bank IOUs, or discounts against bank
assets), as well as central bank purchases of gold or foreign currencies,
injects HPM and can thus substitute for government spending, more narrowly
defined. In practice, in most nations this is done only on a temporary basis
(properly categorized as passive interventions).
�����������
Given these considerations, a balanced budget is the theoretical
minimum that a government can run continuously�again, with the caveat that
if a central bank were willing to continually intervene to lend to banks or to
buy gold and foreign currencies, the treasury could run a persistently
balanced budget, or even a surplus. Normally, if the government were to
attempt to run a surplus, the public would find that its �net money�
receipts of HPM would be less than its tax liability, requiring households to
dip into hoards of HPM (accumulated from past government deficit spending and
purchases of assets) to pay taxes. (Again, an exception must be noted for the
case in which the central bank continually lends to banks or buys gold and
foreign currencies.) Eventually, of course, the hoards would be depleted.
Finally, the public could present maturing government bonds for payment to
obtain HPM with which to pay taxes, but, again, this is limited to the portion
of the outstanding debt stock that is maturing (itself a function of previous
government deficits and the maturity structure of the debt). (It should also
be noted that much of the outstanding debt stock is �locked away� in tax
advantaged accounts, unavailable to a public trying to liquidate claims on
government in order to make tax payments.) After the public has run down its
holding, the only sources of HPM to pay taxes are new government (deficit)
spending or government purchases of assets (including purchases by the central
bank). However, for reasons discussed below, it is highly unlikely that an
economy can withstand the deflationary impacts of government surpluses for
long�thus, we would expect surpluses to be short-lived so that the normal
case is a deficit position and rising government debt over time.
�����������
We have hinted that taxes do not finance government spending. Then what
is their purpose? If the government spent HPM but did not impose an HPM tax,
it is difficult to see why anyone would trade goods and services to the
government in exchange for HPM. Certainly one could not explain the
�origins� of government purchases on the basis of emission of HPM unless
there were already in place a demand for the HPM. This original demand must
have come from imposition of an HPM tax. Of course, once the public has become
accustomed to use of HPM in market exchanges, it might be possible to conceive
of an inertial demand for HPM that could persist for some time even after
abolition of HPM taxes. However, without the tax system to underlie demand, it
is difficult to imagine that the public would continue to use HPM in private
exchanges, and even more difficult to imagine that the public would sell
things to the government in exchange for HPM, if HPM were not needed to make
payments to the government. The tax burden must be sufficiently great to
create a general demand for HPM in order to pay taxes. Beyond that, taxes are
used�as Lerner said�to remove excess HPM income that might generate
spending so great as to generate inflationary pressures. Thus, taxes can be
thought of as one of the spokes of the steering wheel, used to adjust
aggregate demand by reducing disposable income when it becomes too high.
�
�MONETARY POLICY�: BONDS AND INTEREST RATE POLICY
If
government spending is �financed� through emission of HPM, and if tax
revenues are adjusted only to ensure aggregate disposable income is at the
correct level � rather than to �finance� government spending � then
why does the government sell bonds? Of course, governments believe that they
must sell bonds to borrow the funds necessary to financing spending. However,
this is an illusion, as the spending must come first. As we will argue, bond
sales (whether by the treasury or by the central bank) function to drain
excess reserves; they cannot finance or fund deficit spending. This view
builds upon Lerner�s second law of functional finance: �the government
should borrow money only if it is desirable that the public should have less
money and more government bonds� (Lerner, 1943, p. 40). More specifically,
bond sales are designed to substitute an interest-earning government liability
for non-interest-earning government HPM, and is properly thought of as a
monetary policy operation rather than a fiscal policy operation.
�����������
As discussed above, all government spending is initially financed
through issuance of HPM; this normally takes the form of a Treasury check,
deposited at a private bank, increasing bank reserves by the amount of the
government spending. To avoid a situation of excess reserves, a simultaneous
transfer is made from bank tax and loan accounts to the central bank. However,
in the case of a government deficit, the amount of HPM created exceeds the
amount of bank reserves removed through tax payments. In a fractional reserve
system, this normally creates an excess reserve position of the banking
system. Some reserves will be withdrawn by the non-bank public, which holds
some HPM in the form of currency. However, most will remain as excess
reserves.
�����������
Individual banks will offer excess reserves in wholesale markets �
namely, the fed funds market at the fed funds rate � which can shift
reserves around but cannot eliminate the excess. The excess reserves will
force a �market break�, with fed funds offered finding no takers. While it
is true that in the longer run banks can adjust to a position of excess
reserves through normal growth of their loan and deposit portfolio (which, all
else equal, increases required reserves), in the short run the only adjustment
can be to the fed funds rate. Since all modern central banks operate with an
overnight interest rate target, excess reserves automatically trigger bond
sales (typically, reverse repos or matched sale-purchase transactions) by the
central bank to drain excess reserves. Note that prevention of a market break
requires that this operation is nearly simultaneous with the creation of
excess reserve positions.�
�����������
In the US, primary sales of bonds to drain reserves are undertaken by
the Treasury, while the Fed uses repos and reverse repos to �fine-tune� as
it adds/drains reserves to offset daily operating factors. Primary bond sales
permanently �mop up� excess reserves created by government deficits,
providing interest-earning alternatives to non-interest-earning excess
reserves held by banks and cash held by the public.��
If a government were to decide to avoid sales of bonds in primary
markets, the central bank would eventually drain all the reserves it could
through sales of bonds and foreign currency, as it would eventually run out of
bonds and foreign currency to sell. At that point, it would be up to the
Treasury to sell bonds to drain any remaining excess reserves. This reinforces
the view that bond sales are part of monetary policy and not a financing
operation to allow the government to run deficits. It also points out that
rather than deficit spending raising interest rates, it actually places
downward pressure on interest rates. If the government did not drain the
excess reserves, the overnight (fed funds) interest rate would tend to fall
toward zero.
�����������
Government spending is never constrained by the quantity of bonds that
markets are willing to purchase; rather, bond sales are undertaken to provide
an interest-earning alternative to cash and excess reserves. Government
spending is constrained only by private sector willingness to provide goods,
services or assets to government in exchange for HPM. Anything that is for
purchase in terms of the domestic currency can be had through government
creation of HPM. If excess reserves result, the government will have to drain
them if it wishes to hit a positive interest rate target.
������������
Governments sometimes believe that they must sell bonds in
international markets because domestic markets are already saturated with
bonds and any further domestic sales would require higher interest rates.
While this can be true, it has reversed the causation: the government does not
�need� to sell bonds at all; bond sales are by design an �interest rate
maintenance� operation. Thus, while it might be true that at a higher
interest rate government might induce the public and banks to give up some HPM
(although this effect is probably quite small because the demand for HPM is
highly interest-inelastic), this is not an indication that the government is
�forced� to pay higher rates to �finance� its deficit. It can always
incur more deficits and then drain resulting excess reserves at any interest
rate above zero that it desires.
�����������
Since bond sales are really nothing more than an interest rate
maintenance operation, the government can decide the interest rate it will pay
� or, alternatively, the price of government bonds � in its monetary
policy. Thus government deficit spending is never subject to �market
discipline� regarding either the quantity of bonds sold or the price at
which they will be sold, so long as the bonds are issued in the domestic
currency. When there are excess reserves, the market will �demand� bonds
at any interest rate above zero, for the alternative is non-earning excess
reserves. There may be very good reasons for maintaining a significantly
positive interest rate on government bonds, but it is never necessary to do so
merely because the market would like a high interest rate. A high government
borrowing rate is evidence that the government (treasury plus central bank)
has chosen a high interest rate � it tells us nothing about �market
forces� of supply and demand. The government can always have a lower
interest rate merely by reducing the interest rate target. Interest rates are
determined by monetary policy and cannot be affected by fiscal policy.
�����������
Note that both bond sales and payment of taxes drain HPM from the
economy. However, they serve different purposes. Taxes are used to drain
excessive disposable income and to reduce private sector net (or
�outside�) wealth to prevent aggregate demand from becoming too high. This
is a legitimate function of fiscal policy. However, bond sales�whether
conducted by the Treasury or the Fed�are a function of monetary policy.
Furthermore, bond sales merely change the form of outside wealth�from
holdings of HPM to holdings of interest-bearing debt�but leave wealth
intact. Thus, while orthodoxy frequently sees bond sales and taxes as
�alternative� means of �financing� government spending, they actually
serve quite different functions and have quite different impacts on the
economy.

FUNCTIONAL
FINANCE APPLIED TO NEW MILLENNIUM BUDGET SURPLUSES
According
to President Clinton's 1999 and 2000 State of the Union addresses, we are on a
course to run federal government budget surpluses for the next 15 to 25 years.
On current projections, these surpluses are so large that all the publicly
held debt of the US government would be completely eliminated by 2015. The
President actually proposed that some portion of the surplus be �set
aside� to be held in Social Security trust funds. For example, if a budget
surplus of $100 billion were to accrue in one particular year, $100 billion
worth of government bonds held by the public would be retired, while perhaps
$60 billion worth of new government debt would be created to be held in the
trust fund. This would be described as �saving� 60% of the budget surplus
to be used later when babyboomers retire.
�����������
The President�s analyses have been well received. A number of
prominent economists, including at least six Nobel winners circulated an open
letter after the 1999 State of the Union address dubbing the president's plan
"good economics" and stating that "Although no one can predict
how large the budget surpluses will turn out to be, we can be sure that saving
them by reducing outstanding government debt is an excellent way to ease the
burden on future workers of supporting an aging population." Lawrence
Summers, now Secretary of the Treasury, and Janet Yellen, chair of the
President's Council of Economic Advisers, assured us that the president's
proposal to "lock away" most of the projected budget surpluses in
the Social Security Trust Fund is based on "sound accounting" and
that it will extend Social Security's solvency through 2055. David Broder's
Washington Post article (February 7, 1999) proclaimed the plan to be "the
greatest gift to our children" because it will "help grow the
economy" by "raising national savings." Unfortunately, the
accounting is not sound, and a policy that would preserve surpluses in an
attempt to retire Treasury debt held by the public is anything but a gift to
our children.
�����������
With one brief exception, the federal government has been in debt every
year since 1776. In January 1835, for the first and only time in U.S. history,
the public debt was retired, and a budget surplus was maintained for the next
two years in order to accumulate what Treasury Secretary Levi Woodbury called
"a fund to meet future deficits." (See Wray 1998, p. 63, and Stabile
and Cantor 1991.) In 1837 the economy collapsed into a deep depression that
drove the budget into deficit, and the federal government has been in debt
ever since. Since 1776 there have been six periods of substantial budget
surpluses and significant reduction of the debt. From 1817 to 1821 the
national debt fell by 29 percent; from 1823 to 1836 it was eliminated
(Jackson's efforts); from 1852 to 1857 it fell by 59 percent, from 1867 to
1873 by 27 percent, from 1880 to 1893 by more than 50 percent, and from 1920
to 1930 by about a third. (Thayer 1996) The United States has also experienced
six periods of depression. The depressions began in 1819, 1837, 1857, 1873,
1893, and 1929. Every significant reduction of the outstanding debt has been
followed by a depression, and every depression has been preceded by
significant debt reduction. Further, every budget surplus has been followed,
usually sooner rather than later, by renewed deficits. However,
correlation�even where perfect�never proves causation. Is there any reason
to suspect that government surpluses are harmful?
�����������
At the macroeconomic level, government expenditures generate private
sector income; taxes reduce disposable income. When government spending
exceeds tax revenue (a budget deficit), there is a net addition to private
sector disposable income. This addition may well have secondary and tertiary
and even further effects (for example, households may spend on goods produced
domestically or abroad, thereby raising consumption or imports as measured in
national GDP accounts). Some of that extra disposable income is devoted to
saving, first accumulated in the form of HPM which is then exchanged for
interest-earning government debt when the Treasury sells bonds. Even if the
Treasury did not sell the bonds, however, the private sector would be
(nominally) wealthier by an amount equal to the government's deficit, but this
would be held in the form of non-interest-earning cash (and bank reserves) for
the simple reason that the total value of checks issued by the Treasury to
finance expenditures would exceed the total value of checks written by the
private sector to pay taxes.
�����������
On the other hand, when tax revenues exceed government spending (a
budget surplus), private sector disposable income is reduced. Again, there may
be further effects (consumers may cut back spending, for example). Because
checks received by the Treasury exceed the value of checks issued by the
Treasury whenever there is a surplus, outstanding cash and bank reserves will
be reduced. To restore cash and reserves, the private sector sells Treasury
bonds. The bonds are purchased by the Fed and the Treasury; the purchase
restores reserves and cash. (Sales of bonds between private sector entities
cannot add reserves or cash; they simply shift reserves and cash from one
"pocket" to another.) Note that if the Treasury refused to buy the
bonds (that is, refused to retire outstanding debt), then only the Fed would
be left to buy them. This is why any sustained surpluses must be met by
Treasury retirement of the debt, for otherwise the Fed would accumulate vast
holdings of Treasury debt (on which the Treasury pays interest) while the
Treasury would hold huge deposits in its checking account at the Fed. (In
practice, the Treasury tries to end each day with a deposit of $5 billion.)
For this reason, it is quite silly to argue about �what to do with the
surplus� and to debate about whether some of the surplus ought to be used to
retire outstanding debt. In truth, simple accounting ensures that if the
government taxes more than it spends, it has reduced the private sector�s
holdings of claims on government.
�����������
Movements of the budget position are largely automatic. Rapid economic
growth, such as that experienced in the United States since 1992 or in Japan
previous to 1988, tends to cause tax revenues to rise faster than government
spending, resulting in surpluses. Recessions and depressions tend to cause tax
revenues to fall as spending rises, resulting in deficits. Many economists
focus on the secondary or tertiary effects of government deficits and
surpluses. While they might agree that deficits increase disposable income and
private sector wealth, they argue that deficits also increase interest rates
and thus depress investment or that households reduce consumption on the
expectation that tax rates will be increased in the future. They argue that
while surpluses might reduce disposable income and private sector wealth, they
also lower interest rates and thus spur private capital formation. While I
believe these arguments are based on faulty reasoning (the belief that
deficits push up interest rates, for example, is based on the flawed notion
that interest rates on government bonds are competitively set, and the
�Ricardian Equivalents� argument is based on the flawed view that bond
sales and taxes �finance� government spending), it is possible that under
some conditions the secondary effects might outweigh the primary effects so
that, at least for a while, deficits might depress the private sector and
surpluses might stimulate it. However, history and theory suggest that over
the longer run, deficits can allow the economy to grow while surpluses can
inhibit growth.
�����������
If, as projected, the federal government continues to run surpluses
(resulting in Treasury debt retirement), this must as a matter of course
remove $4.5 trillion of private sector income and wealth over the next 15
years. Can an economy withstand such a bloodletting? Our own history suggests
not, and we can also look to the recent experience of Japan.
�����������
Since WWII we have had the longest depression-free period in the
nation�s history. However, we have had nine recessions, each of which was
preceded by a reduction of deficits relative to GDP. The deficit fell rapidly
toward the end of the Carter presidency, preceding the deepest recession since
the Great Depression. In spite of President Reagan's pledge to balance the
budget, he presided over the largest deficits we had seen since World War II.
To some extent, the deficits grew because of the economic slowdown; however,
tax cuts and spending increases (primarily for defense) caused a discretionary
increase of the deficit. The "Reagan boom" lasted from November 1982
to July 1990, the longest expansion in the postwar period (until it was
surpassed by the Clinton expansion). Predictably, this reduced the deficit
relative to GDP and preceded the Bush recession. In the early years of the
Clinton presidency, the deficit grew again and was projected to continue.
However, as a result of the long expansion and budget agreements, the deficit
was entirely eliminated, and we experienced our first budget surplus in a
generation.
�����������
Indeed, as Godley (1999) has demonstrated, the turn-around of the
budget from deficit to surplus was the sharpest in the postwar period. The
budget now seems to be so biased toward restraint that economic growth will
generate continued surpluses. Given a US trade account deficit and a
government budget surplus, economic growth is made possible only by a domestic
private sector deficit�that is, by private expenditures exceeding private
income.[xiv]
Godley has demonstrated that the gap between private income and spending had
reached entirely unprecedented levels by 1998�and that gap continues to
increase each year in which GDP grows. Continued private sector deficits also
mean growing private sector indebtedness�which by 1999 had also reached
record levels. While it is impossible to say with certainty when the private
sector will finally decide to retrench, it is simply not conceivable that
private sector deficits and debts will grow without limit. Returning to our
discussion above, there is no �deep� accounting necessity that sets a
strict limit to the private sector�s ability to spend more than its income.
By the same token, neither theory nor evidence would suggest that households
and firms would deficit spend at an increasing rate forever. It is curious
that those who would deny that the government can deficit spend in perpetuity
would argue that the private sector will deficit spend for the next two
decades in order to allow the government to retire all its debt.
�����������
Americans know that Japan's growth rate in the 1980s was the envy of
the world, but they are generally unaware that the government deficits as a
percent of GDP rivaled those in the United States. The enormous growth of the
1980s caused government tax revenue to rise faster than spending so that by
the late 1980s the budget moved to surplus. The Japanese economy moved into a
recession-cum-depression from which it has not been able to recover.
Government deficits have been restored, but as a result of the sluggish
economy, not as a result of discretionary, expansive, fiscal policy. While
there have been some small initiatives to cut taxes and increase government
spending, Japan has primarily relied on monetary policy to get it out of
recession. Indeed, Japan held interest rates essentially at zero in an attempt
to stimulate the economy. To this point, the most expansive monetary policy
the world has seen since World War II still has not succeeded in jump-starting
Japan's economy. This might serve as a cautionary tale for those who believe
that Chairman Greenspan can keep the U.S. expansion going in spite of budget
surpluses that are expected to rise well above 2 percent of GDP early this
millenium.
�����������
It is difficult to take seriously any analysis that begins with the
projection that our government will run surpluses for the next 15 or 25 years.
Part of our skepticism comes from the inherent difficulty in making
projections. Even more important, our economy cannot continue to grow robustly
as the government sucks disposable income and wealth from the private sector
by running surpluses. When the economy slows, the surpluses will disappear
automatically�and because the private sector will eventually demand that the
government stop draining income from the economy. Tax cuts will be rushed
through Congress and the president will put forward spending initiatives.
�����������
Finally, surpluses, even if realized, cannot be "locked away"
for future use�for example, to be used by retiring baby boomers. In every
period that government spending falls short of tax revenues, outstanding
government debt is retired. Equivalently, the private sector's stock of wealth
is reduced (since a budget surplus reduces disposable income, and this shows
up as a reduction of government debt in private portfolios). There is simply
no "surplus" that can be "spent" or even
"saved." Should the government decide to spend more, that simply
increases spending relative to taxes and results in a smaller budget surplus.
When total federal government tax revenue falls short of expenditures
(including those associated with Social Security), this first takes the form
of net injections of HPM. In order to allow the central bank to hit its
overnight interest rate targets, the Treasury will issue new debt to the
public to drain excess HPM. But it must do this whether or not there is a
Trust Fund. Neither budget surpluses over the next 15 years nor accounting
fictions can change that simple fact. There may be good (noneconomic) reasons
for keeping Social Security accounts separately from the rest of the budget,
but this should never lead one to believe that a projected �revenue
shortfall� can be cured by having the government issue IOUs to itself.
CONCLUSIONS
All
modern governments spend by emitting HPM, normally by having the Treasury
issue a check. Taxes are never necessary to �finance� spending, nor,
indeed, is it possible for them to do so. The government must first provide
the HPM before it can receive HPM in tax payment. Thus, taxes serve a
different purpose. The primary function of taxes is to create a demand for HPM�for
why would the private sector provide goods and services to government in
return for HPM unless it needed HPM for taxes? Of course, we recognize that
HPM can be used for many things other than tax payment, but these other uses
must be derivative. Taxes also serve another useful purpose, as Lerner
emphasized: they remove disposable income and destroy private sector net
wealth.
�����������
Far from recommending perpetual deficits come what may, the functional
finance approach recognizes that the private sector can become overheated,
which is remedied through rising taxes to drain HPM and disposable income.
Deficits can be too large, but also too small. We normally expect that a
deficit will be required, however, for the simple reason that the private
sector prefers to accumulate some net wealth in the form of HPM and Treasury
bonds. For this reason, the government will usually be required to run a
deficit, which means that its outstanding debt stock will grow over time. This
is nothing to be feared. The government never faces a �financial
constraint�, so long as its offers of HPM for goods and services are taken.
Bond sales come after government spending, so, like taxes, cannot possibly be
required to �finance� spending. Rather, bond sales are used to drain
excess HPM to maintain a positive overnight interest rate. Whether that
interest rate target is high or low, it must be set discretionarily by the
central bank and then maintained by ensuring banks have the desired level of
reserves. While taxes and bond sales both remove HPM from the economy, taxes
drain income and wealth while bond sales merely offer an interest-earning
alternative to non-interest-earning HPM.
�����������
The functional finance approach concludes that there is no magic
deficit-to-GDP ratio or debt-to-GDP ratio that ought to be maintained or
avoided. It also demonstrates that there is no sense in which budget surpluses
in one year can be �locked away and saved� for spending in future years.
And it leaves one perplexed when faced with the argument advanced by Nobel
winners that running surpluses today�hence, destroying private sector income
and wealth�is the best way to encourage investment in order to enhance
living standards into the future.�

NOTES
[i].Economists often use the term
�finance� to indicate use of money to purchase a good, service or
asset. It usually means the money was borrowed short term. The term
�fund� is used to indicate long-term borrowing. Thus one might borrow
short term temporarily to �finance� a purchase, then use long-term
borrowing to retire the short-term debt and �fund� the purchase long
term.
[ii].The deficits still might be
inflationary either due to �bottle-necks� that lead to supply
constraints and cost-push inflation, or due to excessive aggregate demand
(causing demand-pull inflation) if the economy operates beyond full
capacity.
[iii].It is even conceivable that
�crowding in� might occur � the government�s borrowing actually
increases the demand for private bonds � although most economists do not
pay much attention to this theoretical possibility. Some economists
recognize that some government spending (for example, that on public
infrastructure investment) is likely to increase private sector
productivity and reduce private sector costs, which might encourage
private investment.� See
Aschauer (1998).
[iv]
Both Post Keynesians and Bastard Keynesians have adopted such positions.
For example, Hyman Minsky (1986) argued that Reagan�s deficits were too
large and in danger of generating the belief that the government would
never be able to repay them�which, he thought, might lead to a situation
in which the government would not be able to issue new debt.
�[v]
It is common to assert that the debt-to-GDP ratio must eventually converge
to some value, for a perpetually rising ratio would be
�unsustainable�. An important determinant of �sustainability�
would be the relation between the economy�s growth rate and the interest
rate paid on government debt; if the interest rate exceeds the growth
rate, then debt would explode even if the �primary budget� (excluding
interest spending) were in balance.
�[vi]
See Wray 1998, p. 21.
�[vii]
Although some simply assert that Ponzi finance is unsustainable because it
implies debt ratios that increase without limit. In this case, the
constraint is simply a mathematical constraint.
�[viii]
We prefer to describe government-issued money as HPM rather than fiat
money. We include bank reserves as HPM, while many would not include bank
reserves in the definition of fiat money.
[ix].We
sometimes say that HPM is a government liability. For what is the
government liable? To accept its money in payment of taxes.
[x].
These terms were used by Knapp to describe transactions in the
�private� economy (private pay community) and transactions between the
private sector and the government (public pay community). See Knapp (1924)
and Wray (1998).
[xi].
These terms were used by Knapp to describe the �ultimate� money
created and accepted by government. See Knapp (1924) and Wray (1998).
[xii].
In the case of some extremely large transactions, it is conceivable that
due to obvious problems arising from dealing with large sums of currency,
intermediaries must be used so that no actual currency changes hands. The
sale thus leads to credits and debits on computerized balance sheets of
intermediaries � which leads to reserve-clearing transfers on the
balance sheet of the central bank � but this changes nothing of
principle, and these credits could be exchanged for fiat money both in
theory and in practice.
[xiii].Unless
the tax payment is offset by the Fed�s injection of reserves as it
purchases assets.
[xiv] As
Godley (1999) shows, the private sector�s deficit is identically equal
to the government�s surplus plus the trade deficit.
