The zero lower bound on nominal interest rates has constrained the Federal Reserve’s setting of the overnight federal funds rate for over three years running. According to many macroeconomic models, such an extended period of being stuck at the zero bound has important implications for the...

Using a short-term interest rate as the monetary policy instrument can be problematic near its zero bound constraint. An alternative strategy is to use a long-term interest rate as the policy instrument. We find when Taylor-type policy rules are used to set the long rate in a standard New...

We examine the performance and robustness of monetary policy rules when the central bank and the public have imperfect knowledge of the economy and continuously update their estimates of model parameters. We find that versions of the Taylor rule calibrated to perform well under rational...

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 examine the performance and robustness of monetary policy rules when the central bank and the public have imperfect knowledge of the economy and continuously update their estimates of model parameters. We find that versions of the Taylor rule calibrated to perform well under rational...

This paper considers the joint problem of model estimation and implementation of monetary policy in the face of uncertainty regarding the process of structural change in the economy. We model unobserved structural change through time variation in the natural rates of interest and unemployment....

Researchers have made great strides in improving our understanding of the effects of unconventional monetary policy. Although further study is needed, the evidence from the past few years demonstrates that both forward guidance and large-scale asset purchases are useful policy tools when...
