Abstract

Motivated by the apparent discovery of Edgeworth Cycles in many retail gasoline markets, this article extends the theory of Edgeworth Cycles along several key dimensions, including models of fluctuating marginal costs, differentiation, capacity constraints and triopoly. A computational approach to search for Markov perfect equilibria is taken. Edgeworth Cycles are found in equilibrium in many situations, and the shape of the cycles are found to carry information about underlying competitive intensity. Cycles in triopoly exhibit interesting coordination problems such as delayed starts and false starts.
