We examine a rent-seeking contest by teams, where team members can sabotage their teammates. In this setting, the effective effort (the effort level discounted by the sabotaged level) determines a team's winning probability and the shares of the winning prize. Thus, coordinating the effective...

We investigate a Cournot model with strategic R&D investments wherein efficient low-cost firms compete against less efficient high-cost firms. We find that an increase in the number of high-cost firms can stimulate R&D by the low-cost firms, while it always reduces R&D by the high-cost firms....

This paper formulates a duopoly model in which firms care about relative profits as well as their own profits. Our purpose is to investigate the relationship between the weight of relative performance and R&D expenditure. We find a non-monotone relationship between the weight of relative...

We examine a game of competition with access provision in which service quality is endogenously determined through infrastructure upgrades with spillovers. There are two types of equilibria in the free competition regime. In particular, voluntary access provision with an access charge higher...

This study constructs a model of anticompetitive exclusive-offer competition between two existing upstream firms. Under exclusive-offer competition, the upstream firm's profit depends on the rival's exclusive offer. If the rival makes an exclusive offer acceptable for the downstream firm, the...

It is often argued, though mostly informally, that outward foreign direct investment (FDI) is a synonym for the export of employment and thus detrimental to the home economy. To see whether and under what conditions this intuition indeed holds true, we construct a model of unionized duopoly and...

We consider the spatial competition between two traditional physical (or offline) retailers and an Internet (or online) retailer where the efficiency of the latter differs from that of the former. We assume consumers are heterogeneous across two dimensions: (i) the costs of traveling to either...
