Oligopolistic Pricing and the Effects of Aggregate Demand on Economic Activity

The authors construct a dynamic general equilibrium model in which the typical industry colludes by threatening to punish deviations from an implicitly agreed-on pricing path. They use methods similar to those of F. Kydland and E. Prescott (1982) to calibrate linearized versions of both their model and an analogous perfectly concerning model. The authors then compute the two models' predictions concerning the economy's responses to a change in military spending. The responses predicted by the oligopolistic model are closer to the empirical responses estimated with postwar U.S. data than the corresponding predictions of the competitive model.
