The price commitment model of Maskin and Tirole (1988) provides an extensively cited foundation for Edgeworth cycles. We examine the viability of Edgeworth cycles when price commitment is partial in the sense that a subset of firms are committed to price in each period. If multiple firms are not committed in each period, then the existence of Edgeworth cycle equilibria requires a demanding convexity condition on the profit function.
