We offer a tractable model of tough negotiations and delayed agreement. The setting is an infinite horizon bilateral bargaining game in which negotiators can make strategic commitments to durable offers. Commitments decay stochastically, but uncommitted negotiators can make new commitments. The...

Can two negotiators fail to agree when both the size of the surplus and the rationality of the negotiators are common knowledge? We show that the answer is affirmative. When the negotiators can make irrevocable commitments at a low but positive cost, the unique symmetric equilibrium entails...

Casual observation suggests that people are more generous with their time than with their money. In this paper we present experimental evidence supporting the hypothesis. A third of our subjects demand no compensation for non-monetary investments, whereas almost all subjects demand compensation...

In a laboratory experiment, we create relationships between pairs of anonymous subjects through a Prisoners' dilemma game. Thereafter the same subjects play a private values (sealed-bid double auction) bargaining game with or without communication. Communication substantially increases...

The paper examines the evolutionary foundations of bilateral bargaining behavior, emphasizing the trade-off between commitment and flexibility. When the pie's size is certain, evolution favors the "fair" strategy; accept any share greater than or equal to one half, reject any smaller share. The...
