We study competitive behavior in all-pay Tullock (1980) contests with identity-dependent externalities (IDEs) governed by a fixed network. First, we introduce a model of network contest games, in which the prize generates an externality---which may be positive or negative---that impacts each...

We develop a model of contests on networks. Each player is “connected” to a set of contests and exerts a single effort to increase the probability of winning each contest to which she is connected. We characterize equilibria under the Tullock contest success function and explore how behavior...

Suppose markets and firms are connected in a bi-partite network, where firms can only supply to the markets they are connected to. Firms compete a la Cournot and decide how much to supply to each market they have a link with. We assume that markets have linear demand functions and firms have...

In this article, we analyze the dynamic competition between two platform firms (A&B) in two-sided markets with network externalities. In Period 1, platform A or B wins the contest in a first stage and can serve the two-sided market monopolistically in a second stage. In Period 2, the two...

We show that the presence of loss aversion on the part of participantsin a Tullock imperfectly discriminating contest will significantlyreduce the proportion of the rent dissipated in the form of resourcesused up in the competition for that rent...

Recent economics literature shows renewed interest in models of Bertrand competition with cost uncertainty. We continue this reexamination and introduce cost correlation as a way to mitigate the asymmetry of information between firms facing Bertrand competition. We also allow firms to make an...

Friendship is commonly assumed to reduce strategic uncertainty and enhance tacit coordination. However, this assumption has never been tested across two opposite poles of coordination involving either strategic complementarity or substitutability. We had participants interact with friends or...

Vendettas occur in many real world settings where rivals compete for a prize, e.g., winning an election or a competitive promotion, by engaging in retaliatory aggressive behavior. We present a benchmark experiment where two players have an initial probability of winning a prize. Retaliatory...

This paper experimentally investigates the interdependence between market competition and endogenously emerging inter-firm collaboration. We restrict attention to arrangements resulting from bilateral collaboration agreements that typically characterize real world applications in which the...
