We study the incentives to share private information ahead of contests, such as markets with promotional competition, procurement contests, or R&D. We consider the cases where firms have (i) independent values and (ii) common values of winning the contest. In both cases, when decisions to share...

We consider a model of oligopolistic firms that have private information about their cost structure. Prior to competing in the market a competitive advantage, i.e., a cost reducing technology, is allocated to a subset of the firms by means of a multi-object auction. After the auction either all...

An innovative firm with private information about its indivisible process innovation chooses strategically whether to apply for a patent with probabilistic validity or rely on secrecy. By doing so, the firm manages its rivals’ beliefs about the size of the innovation, and affects the...

We investigate the incentive for partial vertical integration, namely, partial ownership agreements between manufacturers and retailers, when the retailers are privately informed about their production costs and engage in differentiated good price competition. Partial vertical integration...

Consumers often purchase more than one differentiated product, assembling a portfolio, which might potentially affect substitution patterns of demand and, as a consequence, oligopolistic firms’ pricing strategies. To study such consumers’ portfolio considerations, this paper...

Colluding firms often exchange private information and make transfers within the cartels based on the information. Estimating the impact of such collusive practices— known as the “lysine strategy profile (LSP)â€â€” on cartel duration is difficult because of endogeneity and...

We investigate incidence and evolution of patent thickets. Our empirical analysis is based on a theoretical model of patenting in complex and discrete technologies. The model captures how competition for patent portfolios and complementarity of patents affect patenting incentives. We show that...

Does the internet increase competition? To address this question, I exploit two institutional details unique to Germany: (1) Some municipalities received glass fibre cables that cannot be upgraded to DSL; I use these municipalities as a treatment group with reduced online competition. (2) German...

It is often argued that multinationals are reluctant to transfer technology due to the fear of spillovers. We show that this need not be the case if host country policies like taxation are taken into account. Furthermore, we examine the incentives the multinational and the host country have to...

This paper examines a two-period duopoly where consumers are locked-in by switching costs that they face in the second period. The paper's main focus is on the question of how the consumer lock-in affects the firms' choice of product durability. We show that firms may face a prisoners' dilemma...
