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 l...

The goal of this paper is to study the role of multi-product firms in the market provision of product variety. The analysis is conducted using the spokes model of non-localized competition proposed by Chen and Riordan (2007). Firstly, we show that multi-product firms are at a competitive...

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...

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 choice of language is a crucial decision for …rms competing in cultural goods and media markets with a bilingual or multilingual consumer base. To the extent that multilingual consumers have preferences over the intrinsic characteristics (content) as well as over the language of the...

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...

The goal of this paper is to reexamine the optimal design and efficiency of loyalty rewards in markets for final consumption goods.

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...

We analyse the informational content of market shares and prices in a dynamic duopoly model in which consumers have heterogenous information on the quality differential (q) of two goods. It is shown that when firms are poorly informed about q, and therefore the ability of prices to reveal...

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...
