We introduce a model of the retail firm in which consumers and active firms benefit collectively from coordination of sales at fewer firms. Using this model, we show that ostensibly uninformative advertising plays a key role in bringing about coordination economies, by directing consumer search...

We present a theory of collusive pricing in markets subject to business cycle fluctuations. In the business cycle model that we adopt, market demand alternates stochastically between fast-growth (boom) and slow-growth (recession) phases. We provide a complete characterization of the...

We show that when avoidable fixed costs are introduced into the capacity-and-entry model of Dixit(1980) and Ware(1984), there arises a coordination problem in selecting among postentry Nash equilibria. Elimination of weakly dominated strategies makes it possible for the entrant to us a...

We develop a simple model of retail competition in which retailers select prices and investments in cost reduction. Unable to observe firms' current prices prior to costly search, consumers monitor firms' historic pricing behavior. An equilibrium is constructed in which several identical firms...

Empirical studies have repeatedly documented the countercyclical nature of trade barriers. In this paper, we propose a simple theoretical framework that is consistent with this and other empirical regularities in the relationship between protection and the business cycle. We examime the ability...
