This paper investigates the robustness of the dynamic properties of staggered-contracts models. The author first analyzes the persistence of several different types of shocks in a model with constant nominal wages over the life of the contracts. The dynamic pattern of the effects of some types...

A model in which nominal wages are set by contracts that have cost-of-living objectives is likely to be consistent with the evidence of a unit root in the real GNP process of many countries. Values of the autoregressive root in the GNP process are calculated numerically for many countries using...
