    Abstract: When dealing with consumer choices, social pressure plays a crucial role; also in the context of market competition, the impact of network/social effects has been largely recognized. However, the effects of firm-specifc social recognition on market equilibria has never been addressed so far. In this paper, we consider a duopoly where competing firms are differentiated solely by the level of social (or network) externality they induce on consumers' perceived utility. We fully characterize the subgame perfect Nash equilibria in locations, prices and market shares. Under a scenario of weak social externality, the firms opt for maximal differentiation and the one with the highest social recognition has a relative advantage in terms of profits. Surprisingly, this outcome is not persistent; excessive social recognition may lead to adverse coordination of consumers: the strongest firm can eventually be thrown out of the market with positive probability. This scenario is related to a Pareto inefficient trap of no differentiation.

    Abstract: In contrast to empirical evidence, recent theories of cross-border mergers and acquisitions (M&As) assume perfect knowledge transfers – from high to low productivity firms – between acquirer and target. Using the Melitz (2003) model of heterogeneous firms, we develop a matching model of cross-border M&As which allows for both perfect and imperfect knowledge transfers, where the latter leads to assortative matching on productivity for firms in cross-border M&As. This is in line with stylized facts (because M&As frequently occur between firms of similar productivity) and in contrast to the proximity-concentration trade-off (in which only the most productive firms have a physical presence in foreign markets). Allowing for M&As raises the firm viability cut-off level, average productivity and welfare in our model. The welfare benefits are weaker for more imperfect knowledge transfers.

  3. By: Sander Heinsalu
    Abstract: I show that firms price almost competitively and consumers can infer product quality from prices in markets where firms differ in quality and production cost, and learning prices is costly. Bankruptcy risk or regulation links higher quality to lower cost. If high-quality firms have lower cost, then they can signal quality by cutting prices. Then the low-quality firms must cut prices to retain customers. This price-cutting race to the bottom ends in a separating equilibrium in which the low-quality firms charge their competitive price and the high-quality firms charge slightly less.

  4. By: Bonatti, Alessandro; Cisternas, Gonzalo
    Abstract: A long-lived consumer interacts with a sequence of firms in a stationary Gaussian setting. Each firm relies on the consumer's current score--an aggregate measure of past quantity signals discounted exponentially--to learn about her preferences and to set prices. In the unique stationary linear Markov equilibrium, the consumer reduces her demand to drive average prices below the no-information benchmark. The firms' learning is maximized by persistent scores, i.e., scores that overweigh past information relative to Bayes' rule when observing disaggregated data. Hidden scores--those only observed by firms--reduce demand sensitivity, increase expected prices, and reduce expected quantities.

    Abstract: This paper investigates the strategies of a data broker in selling information to one or to two competing firms that can price-discriminate consumers. The data broker can strategically choose any segment of the consumer demand (information structure) to sell to firms that implement third-degree price-discrimination. We show that the equilibrium profits of the data broker are maximized when (1) information identifies the consumers with the highest willingness to pay; (2) consumers with a low willingness to pay remain unidentified; (3) the data broker sells two symmetrical information structures. The data broker therefore strategically sells partial information on consumers in order to soften competition between firms. Extending the baseline model, we prove that these results hold under first-degree price-discrimination.
    Keywords: data broker, information structure, price-discrimination
