Cusbert, ThomasAbstract
This thesis develops a model in which homogeneous producers and merchants interact repeatedly in a search market. Merchants are able to reduce the cost of search by o ering trading certainty to pro- ducers with whom they have a preexisting relationship. Equilibria are characterised in Markov strategies, and it is found that price- dispersed equilibria exist in asymmetric strategies. Conditions in which a price-dispersed equilibrium can be welfare improving com- pared to a single-price equilibrium are found, and two extensions to the basic model are provided.This thesis develops a model in which homogeneous producers and merchants interact repeatedly in a search market.
