This paper evaluates the importance of microeconomic irreversibilities for aggregate dynamics using a general equilibrium approach. To this end a real business cycle model of establishment level dynamics is formulated and analyzed. Investments decisions are subject to irreversibility constraints...

This paper evaluates to what extent the introduction of firing costs can affect the aggregate dynamics of a neoclassical growth model with heterogeneous establishments. Similarly to the previous literature, firing costs are found to have large steady-state effects. However, they have no...

Shocks to the marginal efficiency of investment are the most important drivers of business cycle fluctuations in US output and hours. Moreover, these disturbances drive prices higher in expansions, like a textbook demand shock. We reach these conclusions by estimating a DSGE model with several...

This paper shows how US monetary policy contributed to the drop in the volatility of US output fluctuations and to the decoupling of household investment from the business cycle. I estimate a model of household investment, an aggregate of non durable consumption and corporate sector investment,...

The U.S. Department of Commerce composite index of leading indicators (CLI) is a widely cited and influential economic series. In this article, Evan F. Koenig and Kenneth M. Emery examine how well movements in the CLI predict business-cycle turning points. Using data that actually would have...

Discussions of the effects of monetary and fiscal policy sometimes center on the impact of such policies in ameliorating fluctuations associated with the business cycle. However, though familiar with the term "business cycle," many people are not aware of what it refers to exactly. In this...

Empirical studies suggest that monetary policy shocks can have a sustained impact on aggregate output. How is it possible for nominal shocks to have persistent real effects? One popular explanation centers on overlapping price contracts. However, recent theoretical work has cast doubt on the...

Some critics of recent monetary policy have focused on slow M2 growth, claiming that the Federal Reserve is too interested in price stability and is forsaking its growth mandate. Others criticize the Fed for achieving price stability too cautiously and urge the adoption of a rule that seeks to...
