We study how conflict in contest games is influenced by rival parties being groups and by group members being able to punish each other. Our motivation stems from the analysis of socio-political conflict. The theoretical prediction is that conflict expenditures are independent of group size and...

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...

We define the canonical form of a cost spanning tree problem. The canonical form has the property that reducing the cost of any arc, the minimal cost of connecting agents to the source is also reduced. We argue that the canonical form is a relevant concept in this kind of problems and study a...

This paper discusses a simultaneous market entry game between two firms with different fixed costs. This case is a typical application of mixed strategy equilibria. Conventional wisdom would suggest that the low-cost firm is more likely to enter the market. This presumption is wrong. Instead,...

This paper analyzes non-fundamental volatility and efficiency in a class of large games (including e.g. linear-quadratic beauty contests) that feature strategic interaction and endogenous information acquisition. We adopt the rational inattention approach to information acquisition but...

This paper studies how to design service outsourcing contracts to ensure fast, quality services from an independent service provider. The outsourcer does not have perfect information about either the service provider's capacity cost (i.e., cost for providing fast service), or her quality cost...

Previous research on gender differences in behavior has led to seemingly contradictory findings about generosity. From data generated by 290 subject pairs, we find that women are more sensitive than men to the costs of generous actions when deciding whether to be generous. The factors that...

We perform a meta analysis of gender differences in the dictator game (DG) by collecting raw data from 53 studies with 117 conditions, giving us 15,016 unique individual observations. We find that women on average give 4 percentage points more than men (Cohen's d=0.16), and that this difference...
