Undertaxed or Overspent?

E.C. Pasour

Americans and many other members of the world economic community are worried about the U.S. government s budget deficits. The deficit in any year is the amount by which Federal expenditures exceed receipts. Recent turmoil in U.S. and other financial markets has been attributed to uncertainties about whether and how U.S. budget deficits will be reduced.[1]

There is widespread agreement that the deficit should be reduced but little agreement about how to do it. Much of the disagreement has been over whether the Federal deficit should be reduced by increasing taxes or by reducing spending. The factual question of whether budget deficits during the Reagan era have risen because of lower taxes or increased expenditures is important in the public policy debate.

Historical spending and revenue data cannot be used to justify current levels of expenditures or taxation. However, it is important that thoughtful citizens as well as those directly involved in deficit-cutting legislation be informed about the origins of the deficits. Have recent deficits been the result of taxes falling more than spending or of spending increasing more rapidly than taxes?

Public support for tax increases appears to be rooted in the widely held belief that the former explanation is correct. That is, rising budget deficits during the 1980s are considered to be the fruits of one aspect of “Reaganomics”-reductions in tax rates. The following analysis, contrary to the conventional wisdom and typical news story, demonstrates that Federal budget deficits have increased since 1980 because of increases in government expenditures-not because of reductions in tax revenues.

Federal Expenditures and Receipts Since 1960

A historical perspective is helpful in studying the relationship between Federal taxes, expenditures, and budget deficits. The budget of the federal government was essentially balanced in 1960, Except for one year (1969), there has been a Federal budget deficit each year during the past quarter century. Indeed, budget deficits during the Reagan Administration have been considerably higher than during any other presidency since 1960. The annual budget deficit as a per cent of Gross National Product (GNP) averaged 4.8 per cent during the first 6 years of the Reagan Administration. In contrast, the deficit reached 4 per cent in only one year (1976) from 1960 to 1981.

Tax receipts as a percentage of GNP averaged 18.2 per cent during the 1960s, 18.3 per cent during the 1970s, and 18.8 per cent since 1980.[2] Thus, despite tax law changes, including significant reductions in tax rates in 1981, Federal tax receipts have increased, and have increased as a share of GNP as well, during the Reagan era. Rising tax receipts mean that increased deficits during this period were rooted in government spending policies.

There was a gradual and sustained increase in Federal expenditures during the 1960s and 1970s. Federal outlays as a per cent of GNP averaged 19.0 per cent during the 1960s and 20.7 per cent during the 1970s. Since 1980, however, Federal expenditures have increased dramatically—averaging 23.6 per cent of GNP.[3] Budget deficits have increased since 1980 because Federal spending has been outstripping tax receipts even though tax receipts are higher, absolutely and as a share of GNP, than they averaged from 1960 to 1980.

Interest Payments and Social Security Expenditures

Some analysts contend that rising budget deficits since 1980 are a result of too little taxation rather than of too much spending. A 1987 study by Citizens for Tax Justice, for example, claims that spending on Federal programs (excluding Social Security and interest payments on the national debt) has declined since 1980 as a share of GNP. In support of this argument, it is shown that total spending excluding interest expense and Social Security declined from 14.9 per cent in 1980 to 14.3 per cent in 1987.[4]

Citizens for Tax Justice attributes increased budget deficits of the 1980s to tax cuts for corporations and high income individuals that began in the late 1970s and accelerated in the early years of the Reagan presidency.[5] The prescription of the Citizens for Tax Justice group is higher taxes on corporations and wealthy individuals, instead of reduced spending for social programs to reduce the budget deficit.

The Citizens for Tax Justice analysis of Federal spending has two major shortcomings. First, even omitting interest expense and Social Security payments from Federal spending data, Federal spending as a share of GNP may not have decreased during the 1980s. For example, total spending as a proportion of GNP averaged 14.5 per cent from 1970 to 1980. Since 1981, however, it has averaged about 15 per cent. Thus, the contention that outlays on Federal programs adjusted in this way have uniformly decreased during the Reagan years is not cor rect, although this comparison is quite sensitive to the years selected. During the decade of the 1960s, for example, Federal spending, excluding interest expense and Social Security, was slightly higher (15.2 per cent versus 15.0 per cent), on average, than during the Reagan era.

The Citizens for Tax Justice approach to the analysis of government spending trends, however, ignores a more fundamental problem. Why should interest expense on the national debt and Social Security payments be omitted in analyzing trends in government spending? Net interest costs were three times as high in fiscal 1986 as in 1980—the last year of the Carter Administration. It is true that interest costs are determined by interest rates and the amount of debt and, in this sense, are beyond the control of Congress or the President. In a more fundamental sense, however, past government policies are responsible for the current level of debt, and present government policies influence both future levels of debt and current interest rates. Inflationary monetary and fiscal policies, for example, tend to raise interest outlays for any given level of debt.

Moreover, the distortions of economic activity associated with taxation are similar whether the tax receipts are used for interest payments on the debt or for any other program. Thus, we should include interest on government debt when analyzing trends in government spending.

The situation is similar for Social Security, even if the program is treated as a self-funding entity. From the standpoint of the individual participant, Social Security is a transfer program rather than an insurance program. Payments made to recipients are not actuarially determined by contributions, as they are in a bona fide insurance program. Thus, there is no reason to exclude Social Security taxes and payments in analyzing trends in Federal spending and taxation.

Conclusions and Implications

There is a great deal of concern but no consensus about the economic effects of increasing Federal deficits. The effects of higher deficits on economic activity, including interest rates, international trade, and private investment, are debated within the economics profession, and a summary of these issues is beyond the purview of this paper. However, Nobel Laureate James Buchanan makes a compelling argument that national debt (like private debt) incurred to finance consumption in some past period is tantamount to a reduction in net wealth. He concludes: “The issue of public debt to finance the great and continuing fiscal spree of the 1960s, 1970s and 1980s has been equivalent, in all relevant respects, to the destruction of capital value.”[6]

Regardless of the economic effects of higher budget deficits, an analysis of the record of the past quarter century clearly reveals the source of the deficits. When compared with the 1960s and 1970s, Federal taxes as a per cent of GNP have not decreased during the 1980s, whereas Federal expenditures as a share of GNP have increased substantially during this period.

Thus, the evidence strongly supports the conclusion of a recent Tax Foundation analysis of the increased budget deficits of the Reagan era: “We are not undertaxed but overspent.”[7] []
