The Cherished Economic Theories Adopted and Applied Since the 1930s Are Tragically and Fundamentally Incorrect

 The current inflationary depression [1974-1975] has revealed starkly to the nation’s economists that their cherished theories—adopted and applied since the 1930s—are tragically and fundamentally incorrect. For forty years we have been told, in the textbooks, the economic journals, and the pronouncements of our government’s economic advisors, that the government has the tools with which it can easily abolish inflation or recession. We have been told that by juggling fiscal and monetary policy, the government can “fine-tune” the economy to abolish the business cycle and insure permanent prosperity without inflation. Essentially—and stripped of the jargon, the equations, and the graphs—the economic Establishment held all during this period that if the economy is seen to be sliding into recession, the government need only step on the fiscal and monetary gas—to pump in money and spending into the economy—in order to eliminate recession. And, on the contrary, if the economy was becoming inflationary, all the government need do is to step on the fiscal and monetary brake—take money and spending out of the economy—in order to eliminate inflation. In this way, the government’s economic planners would be able to steer the economy on a precise and careful course between the opposing evils of unemployment and recession on the one hand, and inflation on the other. But what can the government do, what does conventional economic theory tell us, if the economy is suffering a severe inflation and depression at the same time? Now can our self-appointed driver, Big Government, step on the gas and on the brake at one and the same time?

While Monetarists and Austrians Both Focus on the Role of Money in the Great Depression, the Causal Emphases and Policy Conclusions Are Diametrically OPPOSED

 Furthermore, as in the case of Fisher and Hawtrey, the current monetarists uphold as an ethical and economic ideal the maintenance of a stable, constant price level. The essence of the cycle is supposed to be the rise and fall—the movements—of the price level. Since this level is determined by monetary forces, the monetarists hold that if the price level is kept constant by government policy, the business cycle will disappear. Friedman, for example, in his A Monetary History of the United States, 1867-1960 (1963), emulates his mentors in lauding Benjamin Strong for keeping the wholesale price level stable during the 1920s. To the monetarists, the inflation of money and bank credit engineered by Strong led to no ill effects, no cycle of boom and bust; on the contrary, the Great Depression was caused by the tight money policy that ensued after Strong’s death. Thus, while the Fisher-Chicago monetarists and the Austrians both focus on the vital role of money in the Great Depression as in other business cycles, the causal emphases and policy conclusions are diametrically opposed. 

To the Austrians, the monetary inflation of the 1920s set the stage inevitably for the depression, a depression which was further aggravated (and unsound investments maintained) by the Federal Reserve efforts to inflate further during the 1930s. The Chicagoans, on the other hand, seeing no causal factors at work generating recession out of preceding boom, hail the policy of the 1920s in keeping the price level stable and believe that the depression could have been quickly cured if only the Federal Reserve had inflated far more intensively during the depression.

The Chicago Approach to the Business Cycle Is No More Than a Recrudescence of the Fisher-Hawtrey Purely Monetary Theory of the 1910s and 1920s

Along with the renewed emphasis on business cycles, the late 1960s saw the emergence of the  “monetarist” Chicago School, headed by Milton Friedman, as a significant competitor to the Keynesian emphasis on compensatory fiscal policy. While the Chicago approach provides a welcome return to the pre-Keynesian emphasis on the crucial role of money in business cycles, it is essentially no more than a recrudescence of the “purely monetary” theory of Irving Fisher and Sir Ralph Hawtrey during the 1910s and 1920s. Following the manner of the English classical economists of the nineteenth century, the monetarists rigidly separate the “price level” from the movement of individual prices; monetary forces supposedly determine the former while supply and demand for particular goods determine the latter. Hence, for the monetarists, monetary forces have no significant or systematic effect on the behavior of relative prices or in distorting the structure of production. Thus, while the monetarists see that a rise in the supply of money and credit will tend to raise the level of general prices, they ignore the fact that a recession is then required to eliminate the distortions and unsound investments of the preceding boom. Consequently, the monetarists have no causal theory of the business cycle; each stage of the cycle becomes an event unrelated to the following stage.
