We analyze market dynamics under Bertrand duopoly competition in industries with network effects and consumer switching costs. Consumers form installed bases, repeatedly buy the products, and differ with respect to their switching costs. Depending on the ratio of switching costs to network...

Recent contributions have explored how lack of buyer mobility affects pricing. For example, Burdett, Shi, and Wright (2001) envisage a two-stage game where, once prices are set by the firms, the buyers play a static game by choosing independently which firm to visit. We incorporate imperfect...

This paper analyzes sequential games of double-sided Bertrand competition in the deposit and credit markets, when banks are free to reject customers and cannot distinguish among borrowers. The timing of competition is crucial when customers apply once. Interest rates are pushed upwards when the...

This note extends Kreps and Scheinkman's result -showing that a production capacity choice stage followed by price competition yields the same outcome as a Cournot game- to a setting where capacity costs are asymmetric.

This paper extends Stahl (1988) by modelling a sequential price competition among intermediaries when their expected revenue per sale is affected by consumers’s default. If this revenue is non-monotonie with the asking price, theWalrasian outcome may not be an equilibrium and demand rationing...

In the text-book model of dynamic Bertrand competition, competing firms meet the same demand function every period. This is not a satisfactory model of the demand side if consumers can make intertemporal substitution between periods. Each period then leaves some residual demand to future...

This paper builds a theory of endogenous role distribution (leader, follower, and Nash player) and of endogenous choice for the type of competition strategy (price and quantity) in a product differentiated duopoly model. We examine an extended game by adding a pre-play stage in which duopoly...

The answer is no. Although naive intuition may suggest the opposite, uncertainty about costs in the homogeneous-good Bertrand model intensifies competition: it lowers price and raises total surplus (but also makes profits go up). For some economic environments, this is implied by Hansen’s...

We analyse the efficiency effects of the initial permit allocation given to firms with market power in both permit and output market. We examine two models: a long-run model with endogenous technology and capacity choice, and a short-run model with fixed technology and capacity. In the long run,...

We present a model of imperfect price competition where not all firms can sell to all consumers. A network structure models the local interaction of firms and consumers. We find that aggregate surplus is maximized with a fully connected network, which corresponds to perfect competition, and...
