A key issue in monetary policymaking is the appropriate division of labor between the profes? sional staff of the central bank and the appointed policymakers. Lars E. O. Svensson (1999) argues that the appropriate role of a policymaking group, such as the Federal Open Market Com? mittee (FOMC) in the United States, is to make judgments about social welfare, taking as given the likely outcomes of different policies as esti? mated by the staff. In this division, the staff is relied upon to assess current and prospective economic conditions and to forecast the effects of different policies. Policymakers' only role is to decide which of the various options should be chosen.

This paper develops a measure of U.S. monetary policy shocks for the period 1969–1996 that is relatively free of endogenous and anticipatory movements. Quantitative and narrative records are used to infer the Federal Reserve's intentions for the federal funds rate around FOMC meetings. This series is regressed on the Federal Reserve's internal forecasts to derive a measure free of systematic responses to information about future developments. Estimates using the new measure indicate that policy has large, relatively rapid, and statistically significant effects on both output and inflation. The effects are substantially stronger and quicker than those obtained using conventional indicators.

Monetary policy in the United States in the 1950s was remarkably modern. Analysis of Federal Reserve records shows that policymakers had an overarching aversion to inflation and were willing to accept significant costs to prevent it from rising to even moderate levels. This aversion to inflation was the result of policymakers' beliefs that higher inflation could not raise output in the long run, that the level of output that would trigger increases in inflation was only moderate, and that inflation had large real costs in the medium and long runs. Furthermore, both narrative and empirical analysis indicates that policymakers were not wedded to free reserves or other faulty indicators in their implementation of policy. Empirical estimates of a forward-looking Taylor rule show that policymakers in the 1950s raised nominal interest rates more than one-for-one with increases in expected inflation, and suggests that monetary policy in the 1950s was more similar to policy in the 1980s and 1990s than to that in the late 1960s and 1970s. One implication of these findings is that the inflation of the late 1960s and 1970s must have been the result of a change in the conduct of policy.

This paper tests for the existence of asymmetric information between the Federal Reserve and the public by examining Federal Reserve and commercial inflation forecasts. It demonstrates that the Federal Reserve has considerable information about inflation beyond what is known to commercial forecasters. It also shows that monetary-policy actions provide signals of the Federal Reserve's information and that commercial forecasters modify their forecasts in response to those signals. These findings may explain why long-term interest rates typically rise in response to shifts to tighter monetary policy.
