Consider a situation where two agents obtain gains from cooperation. This could be an exchange that is mutually beneficial or a cooperation in a political or social environment. How should the agents divide the proceeds from their joint project? How is the ratio of goods in an exchange, how the result of a political or personal settlement determined? Market equilibria assume a large number of agents and the presence of a Walrasian auctioneer - assumptions that are not always fulfilled. Bargaining theory attempts to solve these problems and tries to explain how players find a settlement in a distributive conflict. Is the settlement always efficient or is it found only after time consuming and costly negotiations? Who is the winner and who the looser of a settlement? How is bargaining power determined? How, finally, can we compare such a bargaining solution with market equilibria?
Students should understand the main paradigms of axiomatic bargaining theory (Nash, Kalai-Smorodinsky) and of strategic bargaining theory (Rubinstein's alternating offer game). Optionally the course can include applications to markets.
