This paper studies fluctuations in a real business cycle model when there is a risk neutral agent present to offer insurance to workers. This economy is compared with one in which there is no risk neutral agent but labor is indivisible. In static models it is difficult to distinguish the risk...

We introduce procyclical labor and capital utilization, as well as costs of rapidly increasing employment, into a business-cycle model. Plausible variations in factor utilization enable us to explain observed variability of real GNP with considerably smaller economy-wide disturbances. The costs...

We incorporate nominal wage contracts and government into a quantitative general equilibrium framework. Thus, our model includes three types of shocks: a fiscal shock, a monetary shock, and a technology shock. We show that it is possible in this type of environment to generate a low correlation...

A modified version of the nominal contract developed by J. A. Gray (1976) and S. Fischer (1977) is introduced in a general equilibrium model with money which has been used in the real business-cycle literature. Money is introduced in the model through cash-in-advance constraint. Two kinds of...

We study the welfare implications of uncertainty in business cycle models. In the modern business cycle literature, multiplicative real shocks to production and/or preferences play an important role as the impulses that produce aggregate fluctuations. Introducing shocks in this way has the...
