Abstract

This paper studies the endogenous determination of the price formation procedure in markets characterized by match-specific heterogeneity. We study a model of a market in which, in each time period, agents on one side (e.g., sellers) choose whether or not to post a price before they encounter agents of the opposite type. After a pair of agents have encountered each other, their match-specific values from trading with each other are realized. If a price was not posted, then the terms of trade (and whether or not it occurs) are determined by bargaining. Otherwise, depending upon the agents' match-specific trading values, trade occurs (if it does) either on the posted price or at a renegotiated price. We analyze the symmetric Markov subgame perfect equilibria of this market game, and address a variety of issues such as the impact of market frictions on the equilibrium proportion of trades that occur at a posted price rather than at a negotiated price.
