Standardized classroom economics experiments provide a treasure trove of evidence about how well results reproduce when nearly-identical methods are used. We use a sample of around 20,000 observations to test reproducibility in bargaining and trading. Ultimatum bargaining exhibits some...

Experimental studies show that the Nash equilibrium and its refinements are poor predictors of behavior in non-cooperative strategic games. Cooperation models, such as ERC and inequality aversion, yield superior predictions compared to the standard game theory predictions. However, those models...

Delegating bargaining to an intermediary agent is common practice in many situations. The proposer, while not actively bargaining, sets constraints on the intermediary agent's offer. We study ultimatum games where proposers delegate bargaining to an intermediary agent by setting boundaries on...

We report experimental findings on the role of charitable promises in bargaining settings. We vary the enforceability of such promises within variants of ultimatum games where the proposer suggest a split between himself, the responder and a char-itable donation. By reneging on initial pledges,...
