摘要

A fundamental problem in economics is determining how agreements are reached in situations where the parties have some market power. Of particular interest are three questions of efficiency and distribution: (1) How efficient is the agreement. (2) How can efficiency be improved. (3) How are the gains from agreement divided among parties. Here I explore these questions in the context of bilateral monopoly, in which a buyer and a seller are bargaining over the price of an object. Two features of my analysis, which are important in any bargaining setting, are information and impatience. The bargainers typically have private information about their preferences and will suffer some delay costs if agreement is postponed. Information asymmetries between bargainers will often lead to inefficiencies: the bargainers will be forced to delay agreement in order to communicate their preferences. Impatience will tend to encourage an early agreement and will make the parties' communication meaningful. Those with high delay costs will accept inferior terms of trade in order to conclude agreement early; whereas, patient bargainers will choose to wait for more appealing terms of trade.
