Introducing financial frictions and unemployment into a small open economy model
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 standard new Keynesian model in three dimensions. First, we incorporate financial frictions in the accumulation and management of capital. Second, we model the labor market using a search and matching framework. Third, we extend the model into a small open economy setting. Finally, we estimate the model ...
Involuntary unemployment and the business cycle
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 better off if they find a job than if they do not (that is, unemployment is involuntary). We integrate our model of involuntary unemployment into the simple new Keynesian framework with no capital and use the resulting model to discuss the concept of the nonaccelerating inflation rate of unemployment. We ...
DSGE models for monetary policy analysis
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 describes and implements Bayesian moment matching and impulse response matching procedures for this purpose.
