We consider a model with several regions whose technological ability and factor endowments are identical and in which transport costs between regions are non-negligible. Nonetheless, certain goods are sometimes produced by multiple firms all of which are located in the same region. These goods...

We construct a dynamic general equilibrium model in which the typical industry colludes by threatening to punish deviations from an implicitly agreed upon pricing path. We argue that models of this type explain better than do competitive models the way in which the economy responds to aggregate...

This paper tests and confirms the existence of a puzzling phenomenon - the prices of largely unrelated raw commodities have a persistent tendency to move together. We show that this comovement of prices is well in excess of anything that can be explained by the common effects of past, current,...

Hall has pointed out that, when there is perfect competition and price flexibility, labor hoarding alone will not induce the Solow residual measured using labor's share in revenues to be procyclical. We show that, even with perfect competition, a small amount of price rigidity - we assume firms...

This paper extends and evaluates previous work on the positive theory of inflation. We examine the behavior of governments concerned solely with minimizing the deadweight loss from raising revenue through inflation and tax finance. We show that both governments that can commit to future policy...

We present a simple model of populism as the rejection of “disloyal” leaders. We show that adding the assumption that people are worse off when they experience low income as a result of leader betrayal (than when it is the result of bad luck) to a simple voter choice model yields a...
