We analyze a simple dynamic durable good model. 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 equilibrium, the buyer splits the order with positive...

We analyze a dynamic durable good oligopoly model where sellers are capacity constrained over the length of the game. Buyers act strategically in the market, knowing that their purchases may affect future prices. The model is examined when there is one and multiple buyers. Sellers choose their...

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 examine price competition under product-specific network effects, in a duopoly where the products are differentiated horizontally and vertically. When consumers' expectations are not affected by prices, firms may share the market equally, or one firm (possibly the low-quality one) may capture...

We examine a linear city duopoly where firms choose their locations to maximize expected profits, uncertain about how consumers will assess the relative quality of their products. Equilibrium locations depend on the ratio of the expected quality superiority to the strength of horizontal...

We explore the nature of two-part tariff competition between duopolists providing a homogeneous service when consumers differ with respect to their usage rates. Competition in only one price component (the fixed fee or the rate) may allow both firms to enjoy positive profits if the other price...

We examine oligopolistic markets with both intrabrand and interbrand competition. We characterize equilibrium contracts involving a royalty (or wholesale price) and a fee when each upstream firm contracts with multiple downstream firms. Royalties control competition between own downstream firms...

We study informative advertising within a random-utility, non-localized competition model of product differentiation. In a symmetric equilibrium, advertisement is sub-optimal when product differentiation is small, and excessive otherwise. Increasing the number of firms may increase or decrease...

In several interesting markets, demand is an increasing function of past sales because of learning, network externalities or fashion. This paper examines entry into such markets. The two key elements of the model are that firms are uncertain about the demand (and learn in a Bayesian fashion) and...
