Firms compete with prices and qualities in markets where consumers have heterogeneous preferences and cost characteristics. Consumers demand two goods, which can be supplied jointly or separately by firms. We consider two strategy regimes for firms: uniform price-quality pairs, and screening...

We analyze a simple dynamic durable good oligopoly model where sellers are capacity constrained. Two incumbent sellers and potential entrants choose their capacities at the start of the game. We solve for equilibrium capacity choices and the (necessarily mixed) pricing strategies. In...

We consider the equilibrium interplay between sellers' price competition and consumers' perception of product differentiation. We analyze a situation where, before trading, consumers acquire information at a cost about their preferences between sellers' differentiated products. The incentive for...

We study subgame-perfect equilibria of the classical quality-price, multistage game of vertical product differentiation. Each firm can choose the levels of an arbitrary number of qualities. Consumers' valuations are drawn from independent and general distributions. The unit cost of production is...
