Video taped group decision experiments on a two-person investment game were used to elicit the motivational structure of subjects' behavior. A majority of investors trusted (invested) and a majority of receivers reciprocated (returned). Cognition and decision were focused on extremes: total or...

The paper presents the concept of an "imitation equilibrium" and explores it in the context of some simple oligopoly models. The concept applies to normal form games enriched by a "reference structure" specifying a "reference group" for every player. The reference group is a set of other...

This paper experimentally explores group decision-making in a two-player power-to-take game. Discussions preceding group decisions are video taped and analyzed. Each subject first earns an income in an individual effort task preceding the game. The game consists of two stages. First, one group...

In mechanism design problems under incomplete information, it is generally difficult to find decision problems that are first best implementable. A decision problem under incomplete information is first best implementable if there exists a mechanism that extracts the private information and...

In a sequencing problem with linear time cost, Suijs (1996) proved that it is possible to achieve first best. By first best we mean that one can find mechanisms that satisfy efficiency of decision, dominant strategy incentive compatibility and budget balancedness. In this paper we show that...
