Imperfect knowledge, inflation expectations, and monetary policy
This paper investigates the role of imperfect knowledge regarding the structure of the economy on the formation of expectations, macroeconomic dynamics, and the efficient formulation of monetary policy. Economic agents rely on an adaptive learning technology to form expectations and continuously update their beliefs regarding the dynamic structure of the economy based on incoming data. The process of perpetual learning introduces an additional layer of dynamic interactions between monetary policy and economic outcomes. We find that policies that would be efficient under rational expectations ...

The Reform of October 1979: How It Happened and Why
This study offers a historical review of the monetary policy reform of October 6, 1979, and discusses the influences behind it and its significance. We lay out the record from the start of 1979 through the spring of 1980, relying almost exclusively on contemporaneous sources, including the recently released transcripts of Federal Open Market Committee (FOMC) meetings during 1979. We then present and discuss in detail the reasons for the FOMC?s adoption of the reform and the communications challenge presented to the Committee during this period. Further, we examine whether the essential ...

Monetary policy in deflation: the liquidity trap in history and practice
The experience of the U.S. economy during the mid-1930s, when short-term nominal interest rates were continuously close to zero, is sometimes taken as evidence that monetary policy was ineffective and the economy was in a "liquidity trap." Close examination of the historical policy record for the period indicates that the evidence does not support such assertions. The incomplete and erratic recovery from the Great Depression can be traced to a failure to pursue consistently expansionary policy resulting from an incorrect understanding of monetary policy in an environment of very low ...

Robust monetary policy rules with unknown natural rates
We examine the performance and robustness properties of alternative monetary policy rules in the presence of structural change that renders the natural rates of interest and unemployment uncertain. Using a forward-looking quarterly model of the U.S. economy, estimated over the 1969-2002 period, we show that the cost of underestimating the extent of misperceptions regarding the natural rates significantly exceeds the costs of overestimating such errors. Naive adoption of policy rules optimized under the false presumption that misperceptions regarding the natural rates are likely to be small ...

Taylor rules
Taylor rules are simple monetary policy rules that prescribe how a central bank should adjust its interest rate policy instrument in a systematic manner in response to developments in inflation and macroeconomic activity. This paper reviews the development and characteristics of Taylor rules in relation to alternative monetary policy guides and discusses their role for positive and normative monetary policy analysis.

The reliability of inflation forecasts based on output gap estimates in real time
A stable predictive relationship between inflation and the output gap, often referred to as a Phillips curve, provides the basis for countercyclical monetary policy in many models. In this paper, we evaluate the usefulness of alternative univariate and multivariate estimates of the output gap for predicting inflation. Many of the ex post output gap measures we examine appear to be quite useful for predicting inflation. However, forecasts using real-time estimates of the same measures do not perform nearly as well. The relative usefulness of real-time output gap estimates diminishes further ...
