While it is known that information exchange (IE) in a value chain improves resource coordination, scant attention has been paid to two issues. The first issue is the effect of relative bargaining strengths of the parties on whether and how IE will be implemented. The second issue is whether a...

We describe a system for bilateral negotiations in which artificial agents aregenerated by an evolutionary algorithm (EA). The negotiations are governed bya finite-horizon version of the alternating-offers protocol. Several issuesare negotiated simulataneously. We first analyse and validate the...

This paper studies the evolution of effective pre-play communication in game where a single communication round precedes a simultaneous-move, complete-information game.

This paper proposes as a solution concept for games sets of Nash equilibria that are stable against replacement by alternative Nash equilibria. We prove existence, examine some variants that are related to evolutionary solution concepts, and, most importantly, offer a unified approach to...

The paper describes three novel regularities in public choice games, tied to a Darwinian argument about rules that could be expected to govern social choice. Note: This is a revised version of this paper, originally titled "Two Tests For ‘NSNX’ Effects In Cooperation Experiments," and...

A Presidential Address provides one with the opportunity to look backwards and forward. Backwards to understand how we got to where we are now; forwards to suggest paths to further progress. I will focus on the range of research methods that the members of the Society use, how they have evolved...

This article sets the stage for the special issue by indicating the current focus in the literature on applying analytical tools to enlighten policy makers in the practice of counterterrorism in the post-9/1 I era. In particular, the article briefly indicates the main areas of recent work. The...
