The role of unanticipated changes in money growth for aggregate fluctuations is reexamined using the methods of quantitative equilibrium business cycle theory. A stochastic growth model with money is constructed that has the feature, following Lucas (1972, 1975), that production and trade take...

In this paper we compare the cyclical features implied by an RBC model with two technology shocks under several statistical specifications for the stochastic processes governing technological change. We conclude that while a trend-stationary model accounts better for the observed volatilities, a...

In this paper, we develop a general stochastic model of directed search on the job. Analogous to models of random search on the job, the state of the economy in our model includes the infinite-dimensional distribution of workers across different employment states (unemployment, and employment at...

We study a labor market where workers search for jobs both on the job and off the job. In the model, there are aggregate productivity shocks and match-specific shocks. We outline the proof of existence of an equilibrium which we call a block recursive equilibrium (BRE), in which individuals'...

This paper develops a real business cycle model characterized by idiosyncratic employment shocks and quantitatively explores the behavior of aggregate variables under the assumptions of complete and incomplete insurance markets. The results show that the model with incomplete markets produces...

Although it is well known that aggregate variables have slow-moving stochastic components, research on macroeconomic fluctuations has focused primarily on high-frequency movements of the data. I document some interesting lower-frequency facts in U.S. postwar data and investigate whether dynamic...

In this paper, we develop a general stochastic model of directed search on the job. Like in the analogous models of random search on the job, the state of the economy in our model includes the infinite-dimensional distribution of workers across different employment states (unemployment, and...

The specific contribution of endogenous growth models to RBC literature remains unclear since, although the implication of assuming endogenous growth for explaining aggregate fluctuations has already been considered for instance by Gomme (1993) and Ozlu (1996), these papers introduce additional...

The argument that policy risk, i.e., uncertainty about monetary and fiscal policy, has been holding back the economic recovery in the U.S. during the Great Recession has a large popular appeal. We analyze the role of policy risk in explaining business cycle fluctuations by using an estimated New...
