Coordination in games with incomplete information: experimental results

We use experiments to study coordination in games with incomplete information and ask whether an informed player can use cheap talk strategically. Two players decide whether to enter a market where stage game payoffs either form a prisoner’s dilemma or a stag-hunt. One player knows which stage game is played while the other knows only the associated probabilities. When players engage in a prisoner’s dilemma each player prefers unilateral entry. When payoffs form a stag-hunt game, the outcome where neither enters Pareto dominates the outcome where both enter. We ask whether cheap talk aids coordination on the Pareto dominant outcome and whether the informed player can use cheap talk to engineer her preferred outcome. Consistent with previous literature, the benefit of cheap talk depends on the relationship between payoffs and risks. We find that cheap talk benefits informed players only when payoff risks are low. Key Words: cheap talk, coordination, experiments, incomplete information, risk dominance, payoff domiance

Applications of energy methods to finite-difference solutions of the parabolic wave equation

AbstractImplicit finite-difference techniques may be applied readily to solve acoustic wave-propagation problems in diverse ocean environments. For only the most simple cases, however, can the stability of such schemes be established. In this paper the method of energy inequalities is applied to examine the stability and step-size requirements for solving the parabolic approximation to the wave equation

The Suppressive Power of Positive Thinking: Aiding Suppression-Induced Forgetting in Repressive Coping

Participants scoring high and low on a measure of repressive coping style (Mendolia, 2002) first learned a series of related word pairs (cue-target). Half of the cues were homographs. In the subsequent think/no-think phase (Anderson & Green, 2001), they responded with targets on some trials and suppressed thoughts of targets on others. Suppressed targets were always emotionally negative, as were targets associated with baseline cues reserved for the final test. Some participants were provided with emotionally benign or positive substitutes to help them suppress, and these substitutes were related to different meanings of the homographic cues, compared to those established by the targets. On the final test, all cues were presented for target recall. Only the repressors significantly benefited from the provision of positive substitutes to aid forgetting of the negative targets, regardless of the nature of the cues

We Are Not Hiding So Why Can\u27t You Find Us? Attracting Users to Special Collections & Archives

Special Collections & Archives have become the focal point for many research libraries due to the unique materials. However, there are still many faculty and students who are unaware of the potential research value of these collections. This session explores strategies to improve awareness and use
