The goal of this paper is to examine the role of multiproduct firms in the market provision of product diversity. The analysis is conducted within the spatial model of nonlocalized competition proposed by Chen and Riordan (2006). It turns out that the effect of multiproduct firms on product...

The goal of this paper is to study the frequency of new product introductions in monopoly markets where demand is subject to transitory saturation. We focus on those types of goods for which consumers purchase at most one unit of each variety, but repeat purchases in the same product category....

The goal of this paper is to reexamine the optimal design and efficiency of loyalty rewards in markets for final consumption goods. While the literature has emphasized the role of loyalty rewards as endogenous switching costs (which distort the efficient allocation of consumers), in this paper I...

Why do some workers sign contracts with high quitting penalties? Are these restrictions on the workers' mobility perverse for efficiency or workers' welfare? We postulate an answer that hinges on the degree of observability of the worker's performance by alternative employers. When performance...

Many economists and policy analysts seem to believe that loyalty-rewarding pricing schemes, like frequent flyer programs, tend to reinforce firms' market power and hence are detrimental to consumer welfare. The existing academic literature has supported this view to some extent. In contrast, we...

In this paper we study the optimal ex-ante merger policy in a model where merger proposals are the result of strategic bargaining among alternative candidates. We allow for firm asymmetries and, in particular, we emphasize the fact that potential synergies generated by a merger may vary...

Producers of cultural goods and media products can only make their specific contents available to their audiences and readerships through a particular language. The choice of language is a trivial decision if consumers are monolingual. However, the fraction of bilingual consumers is high in some...

This paper studies the price dynamics induced by strategic firm behaviour in the presence of consumer learning about the uncertain quality differential of the products offered by a duopoly. It is found that consumers learn slowly and also that prices converge slowly to full-information levels. A...
