This paper considers price competition in a duopoly with quality uncertainty. The established firm (the `incumbent') offers a quality that is publicly known; the other firm (the `entrant') offers a new good whose quality is not known by some consumers. The incumbent is fully informed about the...

Upstream players produce design ideas and downstream players select among these ideas to develop finished products. Design diversity is valuable at the upstream stage and coordination is valuable at the downstream stage, in the sense that this maximizes the sum of payoffs to all players....

We consider a model of price competition in a duopoly with product differentiation and network effects. The value of a good for a consumer is the sum of a common and an idiosyncratic component. The first captures the vertical dimension of quality, the second captures horizontal differentiation....

Market mechanism may or may not throw up compatibility in markets for systems where network effect arises due to complementarity of component parts of a system. We consider a game, where, in stage 1, the firms decide whether to standardise on a single technological platform or not and at the...

There is growing evidence that low-quality customer service prevails in the mobile telecommunications industry. In this paper we provide theoretical support to this empirical observation by using simple game theoretical models where inefficient low-quality service levels are part of an...

We compare an n-firm Cournot model with a Stackelberg model, where n-firms choose outputs sequentially, in a stochastic demand environment with private information. The expected total output, consumer surplus, and total surplus are lower, while expected price and total profits are higher in...

Alliances between competitors where an established firm provides access to its marketing and distribution channels are an important real-world phenomenon. We analyze a market where an established firm, firm A, produces a product of well-known quality, and a firm with an unknown brand, firm B,...

We model a duopoly in which two-sided platforms compete on both sides of a two-sided market. Platforms (or intermediaries) select the quality they offer consumers, and the prices they charge to consumers and firms. In this model, non-trivial competition on both sides induces non-quasiconcave...
