We conduct an experiment in which subjects play an ultimatum game but, rather than bargaining over money, they bargain over lottery tickets for a prize. Compared to the standard ultimatum game, proposers offer a significantly lower percentage of lottery tickets, which is inconsistent with either...

We collected and analyzed the data sets of all majoritarian Baron and Ferejohn (1989 Am. Pol. Sci. Rev.) experiments through 2018. By exploiting the variation of experimental parameters such as group size and discount factor we are able to test whether or not the theoretical point predictions...

When lawsuits are resolved out of court, what determines the settlement price? This article uses a laboratory simulation and path analysis to estimate the relative importance of measurable variables in determining who wins the battle for the cooperative surplus. In the simulated negotiation...

In reverse auctions, buyers often retain the right to bargain further concessions from the winner. The optimal form of such procurement is an English auction followed by an auctioneer's option to engage in ultimatum bargaining with the winner. We study behavior and performance in this...

We develop a theory of negotiation in which deals have multiple dimensions that can be bundled together. We use theory and experiments to show that in such settings efficient trade is possible even with substantial asymmetric information. The benefits of identifying areas of mutual gain guide...

Case studies of cartels and recent theory suggest that repeated communication is key for stable cooperation in environments where signals about others' actions are noisy. However, empirically the exact role of communication is not well understood. We study cooperation under different monitoring...

We study a giver's generosity depending on her relationship with the recipient and the observer. We assign different group identities to the players using a variation of the minimum group paradigm, and test the effect of group memberships on altruistic giving in the dictator game with a passive...

We study strategic interaction in an experimental social-preferences vacuum chamber. We mute social preferences by letting participants knowingly interact with computers. Our new design allows for indirect strategic interaction: there are several waves in which computer players inherit the...

We conduct multi-person one-shot ultimatum games that reflect important aspects of collective bargaining. In all treatments a proposer has to divide a pie among herself and two groups of three recipients each. She cannot discriminate within, but across groups. A committee with representatives...

We report experimental data from bargaining situations where bargainers can make proposals as often and whenever they want, and can communicate via written messages. We vary the set of feasible contracts, thereby allowing us to assess the focality of three properties of bargaining outcomes:...
