We examine a multinational firm which has a decreasing marginal cost, and the optimal sales tax policies of the regions where that firm operates. We show that the regions set higher sales taxes than those given by a cooperative equilibrium. Each region fails to fully internalize the effects of its tax level on another region's welfare and the incentives for that region's authority. Exponential cost functions which exhibit economies of scale (for example Cobb-Douglas) and linear demand functions satisfy our assumptions. Our results suggest the need to coordinate sales tax levels between countries and between smaller entities, like states in the United States. Smaller regions benefit more from such coordination. Lowering sales taxes in each region increases welfare for all regions, profits for firms, and consumer welfare.

We study a two-player dynamic investment model with information externalities and provide necessary and sufficient conditions for a unique switching equilibrium. Within this setup, we ask whether policymakers should interfere when better informed agents make individual investment decisions. We find that when the public information is sufficiently high and a social planer therefore expects an investment boom, investments should be taxed. Conversely, any positive investment tax is suboptimally high if the public information is sufficiently unfavorable. We also show that an investment tax may increase overall investment activity.

Payment card networks, such as Visa, require merchants' banks to pay substantial "interchange" fees to cardholders' banks, on a per transaction basis. This paper shows that a network's profit-maximizing fee induces an inefficient price structure, over-subsidizing card usage and over-taxing merchants. In contrast to the literature we show that this distortion is systematic and arises from the fact that consumers make two distinct decisions (membership and usage) whereas merchants make only one (membership). These findings are robust to competition for cardholders and/or for merchants, network competition, and strategic card acceptance to attract consumers.

This paper analyzes the technology commercialization strategy of an innovating firm when the incumbent firms possess specialized commercialization capabilities. According to the predominant framework, if the innovation is protected by a strong appropriabilty regime the optimal strategy is to license the innovation to an incumbent product firm. This paper argues by contrast that if the innovating firm has the ability to learn from its commercialization experience, its optimal strategy may be to commercialize alone or to pursue a hybrid arrangement (called co-promotion) whereby it licenses the innovation but retains the rights to participate in the commercialization process. The paper develops a game-theoretic model of the technology commercialization process and derives the conditions under which these different strategies are equilibrium outcomes. It then uses these to explain the pattern of arrangements pursued by biotech firms attempting to commercialize products in the pharmaceutical industry between 1978 and 2008. The results show that a firm is significantly more likely to use the hybrid strategy when there is a higher probability of commercializing a subsequent product in the same product field in future, when there are more firms competing to license the innovation, and when it is in a stronger financial position.
