Most economists agree that the Keynesian multiplier is one. Since government spending is a component of GDP, it has to have at least this much impact. The Keynesian multiplier also applies to decreases in spending.
The International Monetary Fund estimated that a cut in government spending during a contraction has a multiplier of 1. In the s, rational expectations theorists argued against the Keynesian theory. They said that taxpayers would anticipate the debt caused by deficit spending. Consumers would save today to pay off future debt. Deficit spending would spur savings, not increase demand or economic growth. The rational expectations theory inspired the New Keynesians. They said that monetary policy is more potent than fiscal policy.
If done right, expansionary monetary policy would negate the need for deficit spending. They would merely adjust the money supply. President Roosevelt tried to ease the effects of the Great Depression by spending on job creation programs. He created Social Security, the U. President Ronald Reagan promised to reduce government spending and taxes. He called these traditional Republican policies, Reaganomics. He cut income taxes and the corporate tax rate. Instead of reducing the debt, Reagan more than doubled it.
But that helped end the recession. Bill Clinton's expansionary economic policies fostered a decade of prosperity.

First, there is a lag between the time that a change in policy is required and the time that the government recognizes this. Second, there is a lag between when the government recognizes that a change in policy is required and when it takes action. In the United States, this lag can be very long for fiscal policy because Congress and the administration must first agree on most changes in spending and taxes.
The third lag comes between the time that policy is changed and when the changes affect the economy. This, too, can be many months. Yet many Keynesians still believe that more modest goals for stabilization policy—coarse-tuning, if you will—are not only defensible but sensible. For example, an economist need not have detailed quantitative knowledge of lags to prescribe a dose of expansionary monetary policy when the unemployment rate is very high.
Finally, and even less unanimously, some Keynesians are more concerned about combating unemployment than about conquering inflation. They have concluded from the evidence that the costs of low inflation are small. However, there are plenty of anti-inflation Keynesians. Needless to say, views on the relative importance of unemployment and inflation heavily influence the policy advice that economists give and that policymakers accept.
Keynesians typically advocate more aggressively expansionist policies than non-Keynesians. The brief debate between Keynesians and new classical economists in the s was fought primarily over a and over the first three tenets of Keynesianism—tenets the monetarists had accepted. New classicals believed that anticipated changes in the money supply do not affect real output; that markets, even the labor market, adjust quickly to eliminate shortages and surpluses; and that business cycles may be efficient.
In the s, the new classical schools also came to accept the view that prices are sticky and that, therefore, the labor market does not adjust as quickly as they previously thought see new classical macroeconomics. Before leaving the realm of definition, I must underscore several glaring and intentional omissions. First, I have said nothing about the rational expectations school of thought. Other Keynesians accept the view.
But when it comes to the large issues with which I have concerned myself, nothing much rides on whether or not expectations are rational. Rational expectations do not, for example, preclude rigid prices; rational expectations models with sticky prices are thoroughly Keynesian by my definition.
I should note, though, that some new classicals see rational expectations as much more fundamental to the debate. Prior to , Keynesians believed that the long-run level of unemployment depended on government policy, and that the government could achieve a low unemployment rate by accepting a high but steady rate of inflation. In the long run, they argued, the unemployment rate could not be below the natural rate.
So the natural rate hypothesis played essentially no role in the intellectual ferment of the — period. Third, I have ignored the choice between monetary and fiscal policy as the preferred instrument of stabilization policy. Economists differ about this and occasionally change sides.
By my definition, however, it is perfectly possible to be a Keynesian and still believe either that responsibility for stabilization policy should, in principle, be ceded to the monetary authority or that it is, in practice, so ceded. In fact, most Keynesians today share one or both of those beliefs. Keynesian theory was much denigrated in academic circles from the mids until the mids. It has staged a strong comeback since then, however. The main reason appears to be that Keynesian economics was better able to explain the economic events of the s and s than its principal intellectual competitor, new classical economics.
True to its classical roots, new classical theory emphasizes the ability of a market economy to cure recessions by downward adjustments in wages and prices. Misperceptions would arise, they argued, if people did not know the current price level or inflation rate. But such misperceptions should be fleeting and surely cannot be large in societies in which price indexes are published monthly and the typical monthly inflation rate is less than 1 percent.
Therefore, economic downturns, by the early new classical view, should be mild and brief. Keynesian economics may be theoretically untidy, but it certainly predicts periods of persistent, involuntary unemployment. According to the early new classical theorists of the s and s, a correctly perceived decrease in the growth of the money supply should have only small effects, if any, on real output.
