First, the paper lays out the fun-damental assumptions underlying the game theoretical analysis of international environmental problems. Second it summarises important findings which help to explain the difficulties of co-operation and discusses remedies. Chapter 3 looks at measures to avoid...

In a society composed of a ruler and its citizens: what are the determinants of the political equilibrium between these two? This paper approaches this problem as a game played between a ruler who has to decide the distribution of the aggregate income and a group of agents/citizens who have the...

This paper studies sabotage in a contest with non-identical players. Unlike previous papers, we consider sabotage in an elimination contest and allow contestants to sabotage a potential or future rival. It turns out that for a certain partition of players there is a pure-strategy equilibrium in...

We characterize the equilibrium of the all-pay auction with general convex cost of effort and sequential effort choices. We consider a set of n players who are arbitrarily partitioned into a group of players who choose their efforts ?early? and a group of players who choose ?late?. Only the...

In this paper we deal with voluntary and compulsory redistribution in an economy where the enforcement of property rights is costly. Two agents engage in a common-pool contest and two types of potential distortions arise: the waste of resources in the contest and the dilution of incentives to...

The key element of models of contest is the Contest Success Function (CSF) which specifies the winning probabilities of agents. The existing axiomatizations of CSFs assume that contestants can make only one type of investment. This paper generalizes these axiomatizations to the case where each...

We document an increase in the scoring probability from penalties in soccer, which separates the time period before 1974 significantly from that after 1976: the scoring probability increased by 11%.We explain this finding by arguing that the institution of penalty-shooting before 1974 is best...

We study how norms can solve distributional conflict inside a clan and the efficient coordination of collective action in a conflict with an external enemy.We characterize a fully non-cooperative equilibrium in a finite game in which a self-enforcing norm coordinates the members on efficient...

Conflict parties are frequently involved into more than one conflict at a given time. In this paper the interrelated structure of conflictive relations is modeled as a conflict network where opponents are embedded in a local structure of bilateral conflicts. Conflict parties invest in specific...

We develop a theory of interstate conflict in which the degree of genealogical relatedness between populations has a positive effect on their conflict propensities because more closely related populations, on average, tend to interact more and develop more disputes over sets of common issues. We...
