In this paper, I modify Varian's (1980) model of sales to allow for heterogeneity in consumer preferences. I show that in mixed strategy equilibria each firm charges a finite number of prices. Using this characterization, I examine the e¤ect of consumer heterogeneity on firms' optimal pricing...

We investigate the effect of stock discovery on the profits of non-identical oligopolists. We show that a uniform addition to all stocks could harm firms that are originally larger than average. One conclusion that could be drawn from the results is that a new technology that leads to more...

This Paper characterises the unique Markov equilibrium in the sequential move, finite horizon pricing duopoly with discounting. Simple, short cycles repeat until the last two periods. For discount factors above 0.75488, there are three-period reaction function cycles and below 0.75488,...

In technology-based industries, incumbent firms often license their technology to other firms that will potentially compete with them. Such a strategy is difficult to explain within traditional models of licensing. This paper extends the literature on licensing by relaxing the assumption of a...

This paper analyzes the effects of a potential spillover on technology transfer of a multinational enterprise and on the host country policy. In particular, we examine how both parties’ incentives can be controlled through the ownership structure in an international joint venture. In contrast...

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...

Unprecendented growth of barter is a striking phenomenon of Russia's transition. The explanations of barter include tight monetary policy, tax evasion and poor financial intermediation. We show that the market power may also be important. We build a model of imperfect competition in which firms...

We introduce a framework that has known models of oligopolistic competition with differentiated products (the circle and the constant elasticity of substitution (CES)) as limit cases. This integrative approach incorporates both localized and global competition, as well as price-sensitive...

Price dispersion is ubiquitous in settings that closely approximate textbook Bertrand competition. We show (Propositions 2 and 3) that only a little bounded rationality among sellers is needed to rationalize such dispersion. A variety of statistical tests, based on data sets from two independent...

A safe and a risky seller serve a market. While the expensive safe seller can solve the problems of all consumers, the cheap risky seller can help a consumer only with a certain probability. The risky seller's success probabilities are distributed across consumers; by the choice of her quality...
