چکیده

Uncertainty about the coordination of common efforts (e.g. team projects, alliances) often coexists with uncertainty about other variables (e.g. weather, market fluctuations, political instability). In certain coordination games in which equilibria can potentially arise at any common effort level, ex ante equilibrium selection (particularly of high-effort, high-payoff equilibria) has been a persistent game theoretical challenge. This is largely due to the strategic uncertainty of each participant about the behavior of others, in the absence of communication and credible commitment. We performed experiments in which exogenous noise was added to the decisions of participants in a minimum-effort coordination game. Results indicate that this added contingent uncertainty can prevent perfect coordination at the lowest-payoff equilibrium, and thus make coordination at higher-payoff equilibria possible.

Strategic Decision Comprehensiveness and New Product Development Outcomes in New Technology Ventures

With a sample of new technology ventures in China, we investigated the contingent effect of strategic decision comprehensiveness on new product performance and product quality. The relationship between strategic decision comprehensiveness and new product performance was negatively moderated by technology uncertainty but positively moderated by demand uncertainty. The effect of decision comprehe...

Strategic Uncertainty in a Coordination Game

This work develops a model of strategic uncertainty in the context of a coordination game. A tractable dynamic system determines the evolution of behavior and beliefs. The learning process is multifaceted as behavior is controlled not only by simple responses that result from reinforcement learning but it is also influence by Bayesian inferences and strategic reasoning. Strategic uncertainty ca...

Noisy Best Response in Coordination Games

In an environment with strategic interaction, multiple equilibria yields a coordination problem and strategic uncertainty, even in the idealized setting of complete information. The resulting disequilibrium of beliefs leads to coordination failure, as demonstrated by many experiments. This paper examines two such coordination problems: the threshold game with a unitary public good and the marke...
