This paper surveys some of the strategic aspects that emerge if players fight in an alliance against an enemy. The survey includes the free-rider problem and the hold-up problem that emerges in the baseline model, the role of supermodularity in alliance members' effort contributions, the role of...

This paper investigates empirically whether decision makers are forward looking in dynamic strategic interactions. In particular, we test whether decision makers in multi-stage tournaments take heterogeneity induced changes of continuation values and the ability of their immediate opponent into...

The paper revisits the problem of wage bargaining between a firm and multiple workers. We show that the Subgame Perfect Equilibrium of the extensive-form game proposed by Stole and Zwiebel (1996a) does not imply a profile of wages and profits that coincides with the Shapley values as claimed in...

We consider a two-player advertising race subject to momentum. Momentum is modelled as a complementarity between current and past campaign spending in a way that is reminiscent of models of addiction and habit formation: the more effective a player's past spending has been, the more effective...

We investigate the choice to conduct interim performance evaluations in a dynamic tournament. When a worker's ability does not influence the marginal benefit of effort, the choice depends on the shape of the cost of effort function. When effort and ability are complementary, feedback has several...

We consider extensive-form games in which players have the option to commit to actions before the game is played. We focus on commitment procedures where players make voluntary irreversible commitments in a prescribed order over the decision nodes. We study whether such commitment procedures may...

Tournaments consisting of iterative matches are a common mechanism for determining how to allocate a prize. For this reason it is important to understand the behavioral as well as the theoretical properties of different tournament structures. Given that laboratory experiments have consistently...

We analyze a repeated game in which countries are polluting as well as investing in technologies. While folk theorems point out that the first best can be sustained as a subgame-perfect equilibrium when the players are sufficiently patient, we derive the second best equilibrium when they are...
