Mechanism design without monotone differences: an example featuring buyer habits

Abstract

Within a simple parametric example, I show that if the buyer’s values fail the monotone differences condition, nonmonotone mechanisms are not just feasible but may even be desirable for a seller. The failure of monotone differences is caused by intertemporal consumption externalities in the form of habits. I show that for an interval of habit parameters the revenue maximizing mechanism is nonmonotone: the seller screens out low and high types.
