A modified version of the nominal contract developed by Gray (1976) and 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. The contract studied is...

The key ingredients of real business cycle models are common. The market structure is perfectly competitive, the forcing process is a technology shock, and in most cases agents are identical. Textbook market structures are introduced in a real business cycle model. The market structures studied...

The reason why the assumption of a representative agent is so popular in the equilibrium business cycle literature is mainly that equilibrium allocations are derived by solving a concave programming problem, whereas once heterogeneity is introduced it is necessary to solve for weights on...

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...
