    Abstract

    Edgeworth price cycles refer to an asymmetric pattern of prices that result from a dynamic pricing equilibrium among competing oligopolists. The resulting time series takes on a sawtooth shape – many small price decreases interrupted only by occasional large price increases. Maskin and Tirole (1988) formalized the theory, and later extensions were provided by Eckert (2003) and Noel (2008). Edgeworth price cycles are the leading theory for explaining the asymmetric price cycles that appear in many US, Canadian, Australian and European retail gasoline markets (e.g. Noel (2007a), Eckert (2002), Doyle et al. (2010), Wang (2009b)). While the gasoline cycles continue to generate public concern with claims of collusion often raised, the current evidence favours Edgeworth price cycles being the result of stronger competition and the source of lower retail gasoline prices.
