The Transmission Mechanism of Monetary Policy

Recently, many economists have credited the late-1990s economic boom in the United States for the easy money policies of the Federal Reserve. On the other hand, observers have noted that very low interest rates have had very little positive effect on the chronically weak Japanese economy. Therefore, some theory of how money affects the economy when it is endogenous would be useful. This paper pursues several such explanations, including the effects of interest rate changes on (1) investment; (2) consumer spending; (3) the exchange rate; and (4) financial markets. The theories of such authors as Kalecki, Keynes, Minsky, and J. K. Galbraith are discussed and evaluated, with an emphasis on the role of cash flow. Some of these theories turn out to be stronger than others when subjected to tests of logic and empirical evidence.
