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...

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...

The authors use a dynamic general equilibrium model to obtain quantitative estimates of the welfare cost of nominal wage contracting. They find that the welfare cost of such contracts can vary quite a lot depending on the degree of indexation, the size and persistence of monetary shocks, and the...

The business cycle implications of optimal wage indexation are investigated in a dynamic general equilibrium model with wage contracts. As in Gray's seminal contribution on wage indexation, it is shown that the optimal degree of indexation depends on the relative volatilities of monetary and...

We use a dynamic general equilibrium model to obtain quantitative estimates of the welfare costs of nominal wage contracts. We find that the welfare costs of such contracts can vary quite a bit depending on the degree of indexation, the size and persistence of money supply uncertainty and the...

This is a survey of the main business cycle models that have been developed since the early '80s. It emphasizes the incorporation of money in the neoclassical growth model. It argues that money contributes substantially to aggregate fluctuations only if nominal rigidities are introduced in the...
