How the Business Cycle Happens Part 1
[This excerpt from the first chapters of Murray Rothbard’s America’s Great Depression (1963)] Reprinted from Mises.org
Study of business cycles must be based upon a satisfactory cycle theory. Gazing at sheaves of statistics without “pre-judgment” is futile. A cycle takes place in the economic world, and therefore a usable cycle theory must be integrated with general economic theory. And yet, remarkably, such integration, even attempted integration, is the exception, not the rule. Economics, in the last two decades, has fissured badly into a host of airtight compartments — each sphere hardly related to the others. Only in the theories of Schumpeter and Mises has cycle theory been integrated into general economics.1
The bulk of cycle specialists, who spurn any systematic integration as impossibly deductive and overly simplified, are thereby (wittingly or unwittingly) rejecting economics itself. For if one may forge a theory of the cycle with little or no relation to general economics, then general economics must be incorrect, failing as it does to account for such a vital economic phenomenon. For institutionalists — the pure data collectors — if not for others, this is a welcome conclusion. Even institutionalists, however, must use theory sometimes, in analysis and recommendation; in fact, they end by using a concoction of ad hoc hunches, insights, etc., plucked unsystematically from various theoretical gardens. Few, if any, economists have realized that the Mises theory of the trade cycle is not just another theory: that, in fact, it meshes closely with a general theory of the economic system.2 The Mises theory is, in fact, the economic analysis of the necessary consequences of intervention in the free market by bank credit expansion.
