A noncooperative foundation of the asymmetric Nash bargaining solution

We consider a noncooperative multilateral bargaining model with heterogeneous time preferences in which the first rejector of a proposal in the current round becomes the proposer in the next round. We show the existence of a stationary subgame perfect equilibrium (SSPE), characterize SSPEs and show the efficiency of SSPEs. We show that any sequence of SSPE payoff profiles converges to the asymmetric Nash bargaining solution weighted by the inverses of discount rates as the bargaining friction vanishes.

A multi-agent bilateral bargaining model with endogenous protocol

People do bargain over how to bargain. We examine the role of individuals’ ability to pursue certain bargaining protocols in a multi-agent bilateral bargaining model. Bargaining protocols are not completely settled, but will emerge endogenously in equilibrium. We show that players’ ability to partially influence bargaining protocols plays a crucial role in determining equilibrium outcomes. When discounting is not too high, there are multiple subgame perfect equilibria, including inefficient ones. As the number of players increases, both the set of discount factors that support multiple equilibrium outcomes and the set of the first proposing player’s equilibrium payoffs expand. The maximum loss of efficiency increases with respect to the discount factor.

Determinants of Consumer Responses to Direct Marketing Media

Abstract

This study examined consumer propensity to respond to direct marketing offers made via catalogs, direct mail, and direct response TV. A comparison of the relative importance of marketer's reputation, advertising exposure frequency, and the product offer revealed that the latter was the most important determinant of consumer response frequency. Marketer's reputation was found to be more important for direct response TV and less important for catalog advertising: neither did high frequency of media exposure appear to impact on responses to direct mail and direct response television. The findings suggest that the maximization of reach rather than frequency could possibly be the primary media communication goal for selling products through direct mail and direct response television.
