U.S. Monetary Policy and Stock Prices: Should the Fed Attempt to Control Stock Prices?

This article rejects the linkages in proposals that the Federal Reserve Bank (Fed) target equity prices. The real federal funds rate (RFF) and stock prices (SP) are uncorrelated; causality tests show a positive effect of SP on RFF and a negative effect of SP on RFF. These results occur as part of the dynamics of a negative cointegrated relationship between SP and RFF. A theoretically expected inverse relation between SP and inflation accounts for the results. The negative effect of SP on FF is also confirmed in a Taylor Rule estimate. Higher stock prices anticipate lower, not higher, inflation.
