23. In a classic paper, Robert Barro has argued that when the government runs a budget deficit, individuals and businesses regard the deficit as a future tax obligation; to avoid future adverse financial consequences of this obligation, taxpayers increase their current savings out of income. Thus the impact of using deficit rather than tax financing is simply to substitute voluntary saving for involuntary saving (taxation). The interest-rate effects of deficits are zero. See Barro’s “Are Government Bonds Net Wealth?” Journal of Political Economy 82 (1974): 1095–1117. Empirical evidence on Barro’s hypothesis is mixed, although Paul Evans has garnered impressive support. See his “Do Large Deficits Produce High Interest Rates?” American Economic Review 75 (1985): 68–87, or “Do Budget Deficits Raise Nominal Interest Rates? Evidence from Six Countries,” Journal of Monetary Economics 20 (1987): 281–300.

The Neoclassical/Austrian Approach: An Overview
In the previous chapter, it was suggested that neoclassical and Austrian economists essentially believed that unemployment varies directly with what was termed “the adjusted real wage.” Increases in the adjusted real wage, other things equal, price some labor out of a job, increasing unemployment. It was further suggested that changes in any of the components of the adjusted real wage could change unemployment. Specifically, unemployment grows with increased money wages, but decreases with increased prices or productivity growth. We now proceed to examine the general validity of this neoclassical/Austrian perspective, and then comment on some general criticisms of the approach. In future chapters, we will analyze more closely the historical experiences that unfolded during the century.
Testing the Basic Model
In its simplest form, the hypothesized model is:
where U stands for the unemployment rate, W for the adjusted real wage (real wages divided by labor productivity), a is a constant term, and b is a coefficient measuring the degree to which unemployment changes with changes in the adjusted real wage.
From information on unemployment and the variables comprising the adjusted real wage, it is possible to perform a statistical evaluation of the neoclassical position. Generally accepted data on the aggregate unemployment rate are available from 1890 to the present.1 Money-wage data are available in abundance, although there is less consensus on which series is appropriate. From 1947, the widely cited official Bureau of Labor Statistics data on money compensation per hour in the business sector are used.2
There is a problem with wage data for the period before 1947. Ideally, wages should be related to a specific period of work effort, so hourly wage data are most desirable. Unfortunately, hourly data are available only for some specific classes of workers, not the economy as a whole. Annual earnings data are available that are much more comprehensive
