Historical data and model simulations support the following conclusion: Inflation is low during stock market booms, so an interest rate rule that is too narrowly focused on inflation destabilizes asset markets and the broader economy. Adjustments to the interest rate rule can remove this source...

We argue that the government spending multiplier can be very large when the nominal interest rate is constant. We focus on a natural case in which the interest rate is constant, which is when the zero lower bound on nominal interest rates binds. For the economies that we consider it is optimal...

Gauti B. Eggertsson's paper (published in NBER Macroeconomics Annual 2010) represents an important contribution to the analysis of fiscal policy in the New Keynesian model when the zero lower bound on the nominal interest rate is binding. The paper accomplishes a great deal. It analyzes two...

Monetary DSGE models are widely used because they fit the data well and can be used to address important monetary policy questions. We provide a selective review of these developments. Policy analysis with DSGE models requires using data to assign numerical values to model parameters. The paper...

We propose a monetary model in which the unemployed satisfy the official U.S. definition of unemployment: people without jobs who are (1) currently making concrete efforts to find work and (2) willing and able to work. In addition, our model has the property that people searching for jobs are...

The current financial crisis has made it abundantly clear that business cycle modeling can no longer abstract from financial factors. It is also clear that the current standard approach of modeling labor markets without explicit unemployment has its limitations. We extend what is becoming the...
