Bargaining and Social Structure
speaker: Edoardo Gallo (University of Oxford)abstract: This paper presents a bargaining model between individuals belonging to different groups where the equilibrium outcome depends on the communication network within each group. Belonging to a group gives an informational advantage: connections help to gather information about past transactions and this information can be used to make more accurate demands in future bargaining rounds. In the long-term there is a unique stochastically stable equilibrium which depends on the peripheral or least connected individuals in each group. Comparative statics shows that a denser and more homogeneous network allows members of a group to obtain a better deal. An empirical analysis of the observed price differential between Asian and white buyers in New York's Fulton fish market is consistent with these predictions. An extension explores an alternative set-up where buyers and sellers belong to the same communication network: if the network is regular and the agents are homogeneous then the equilibrium division is 50-50.
