In the unique equilibrium, parties maximally segregate their opponents' supporters but pool their own supporters into uniform districts. Ceteris paribus, the stronger party...

The tension between allocative efficiency and information aggregation is explored in the context of an auction: k identical objects of unknown quality are auctioned off to n bidders whose tastes affect their valuation of an object of given quality. Bidders receive a signal about the quality of...

Over time the price of the design falls as it spreads across the population. Once sufficiently many consumers own the design it is profitable...

The authors examine the following paradox: in a dynamic setting, equilibria can be radically different in a model with a finite number of agents than in a model with a continuum of agents. They present a simple strategic setting in which this paradox is a general phenomenon. However, the paradox...
