This paper considers evolutionarily stable strategies (ESS) in a take-it-or-leave-it offer bargaining game with incomplete information. We find responders reject offers which yield a higher positive material payoff than their outside option. Proposers, in turn, make more attractive offers than...

We study the role of an imbalance in fighting strengths when players bargain in the shadow of conflict. Our experimental results suggest: In a simple bargaining game with an exogenous mediation proposal, the likelihood of conflict is independent of the balance of power. If bargaining involves...

We study platform design in online markets in which buying involves a (non-monetary) cost for consumers caused by privacy and security concerns. Firms decide whether to require registration at their website before consumers learn the price and all relevant product information. We show that a...

We investigate redistributive taxation in a political economy experiment and determine how different patterns of social mobility affect the choices of redistributional taxes. In the absence of social mobility, voters choose tax rates that are very well in line with the prediction derived in the...

Victorious alliances often fight about the spoils of war. We consider experimentally when members of victorious alliances accept a peaceful division of the spoils, and when they fight against each other, and how the inability to commit to a peaceful division affects their effort contributions in...

We study conflict between two groups of individuals. Using Schaffer's (1988) concept of evolutionary stability we provide an evolutionary underpinning for in-group altruism combined with spiteful behavior towards members of the rival out-group. We characterize the set of evolutionarily stable...

Private provision of public goods often takes place as a war of attrition: individuals wait until someone else volunteers and provides the good. After a certain time period, however, one individual may be randomly selected. If the individuals are uncertain about their cost of provision, but can...

Our experimental analysis of alliances in conflicts leads to three main findings. First, even in the absence of repeated interaction, direct contact or communication, free-riding among alliance members is far less pronounced than what would be expected from non-cooperative theory. Second, this...

This paper analyzes the role of narrowly selfish and other-regarding preferences for the median voter in a Meitzer-Richard (1981) framework. We use computerized and real human co-players to distinguish between these sets of motivations. Redistribution to real co-players has a negative effect on...

This paper analyzes the effects of taxation on trade in a decentralized market. We show that a tax on profits and a transaction tax have opposite implications for information acquisition and trade in the canonical take-it-and-leave-it offer bargaining model. A (marginal) increase of a...
