We study bargained input prices where up and downstream firms can choose alternative vertical partners. We apply our model to bargained airport landing fees where a number of interesting policy questions have arisen. For example, what is the impact of joint ownership of airports? Does airline...

We study a two-stage duopoly game, where, at the first stage, firms choose if adopting or not a social responsibility label. The firm who adopts the social responsibility label (the ethical firm) has high marginal costs, while the firm who doesn’t adopt it (the standard firm), supports low...

This paper investigates the competition between vertically differentiated platforms in two-sided markets. We assume the presence of two competing platforms producing either higher- or lower-quality devices for consumers. Each platform decides the price of its hardware device for consumers and...

A model of interaction between hardware vendors, Intel and AMD, and developers of Windows and Linux operating systems is suggested. Intel and AMD both maximize profits forming a traditional oligopoly, while Microsoft and the community of Linux developers form a mixed duopoly, in which only the...

We embed signaling in the classical Cournot model in which several firms sell a homogeneous good. The quality is known to all the firms, but only to some buyers. The quantity-setting firms can manipulate the price to signal quality. Because there is only one price in a market for a homogeneous...

This paper extends a canonical, game-theoretic framework to examine the relationship between product differentiation and relaxed competition. In its theory, firms compete over an infinite-horizon and discount the future so that relaxed competition is feasible in equilibrium. However, firms face...

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 study the strategic choice of compatibility between two initially incompatible network goods in a two-stage game played by an incumbent and an entrant firm. Compatibility may be achieved by means of a converter. We derive a number of results under different assumptions about the nature of the...

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....

How does the need to signal quality through price affect equilibrium pricing and profits, when a firm faces a similarly-situated rival? In this paper, we provide a model of non-cooperative signaling by two firms that compete over a continuum of consumers. We assume "universal incomplete...
