There is limited theoretical understanding of cost pass-through within markets where prices are dispersed. Under a general demand function, we analyse the effects of cost changes in a seminal model of price dispersion, where some consumers are captive to particular sellers while others are not...

There is widespread evidence that geographical borders reduce trade. This paper presents a theoretical model capable of providing a succinct comparison of three broad forms of trade barriers involving i) trade costs, ii) localized tastes, and iii) information frictions. Despite being...

In this paper we provide game theoretic support for the results of the kinked demand curve. By analyzing an infinitely repeated game where unit costs fluctuate stochastically between a low and a high state over time and where firms follow a price-matching punishment strategy, we demonstrate that...
