This paper employs stochastic simulations of a small structural rational expectations model to investigate the consequences of the zero bound constraint on nominal interest rates. We find that if the economy is subject to stochastic shocks similar in magnitude to those experienced in the U.S....

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 study the design of monetary policy in a low inflation environment taking into account the limitations imposed by the zero bound on nominal interest rates. Using numerical dynamic programming methods, we compute optimal policies in a simple, calibrated open-economy model and evaluate the...

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,...
