This paper provides quantitative estimates of the welfare costs of nominal wage contracts. We find that the welfare costs of such contracts are fairly small and are generally relatively insensitive to changes in the economic environment. We then study how contract length might respond to changes...

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...

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 Show That the Destabilizing Effects of Price Flexibility Due to the Increased Sensitivity of Contract Wages to Labor Market Tightness Depends Critically on an Arbitrary Restriction on the Information Available to Wage Settes Who Ae Negotiating Contact Renewals. If These Agents Are Put on the...
