In theory, competitive emission permit markets minimise total abatement cost for any emissionceiling. Permit markets are often imperfectly competitive, however, if they are thin anddominated by large firms. The dominant firm(s) could exercise market power and increase otherfirms’ costs of...

Experimental evidence has accumulated highlighting the limitations of formal and explicit contracts in certain situations, and has identified environments in which informal and implicit contracts are more efficient. This paper documents the superior performance of explicit over implicit...

Costless pre-play communication has been found to effectively facilitate coordination and enhance efficiency by increasing individual payoffs in games with Pareto-ranked equilibria. We report an experiment in which two groups compete in a weakest-link contest by expending costly efforts....

This study reports a laboratory experiment wherein subjects play a hawk-dove game. We try to implement a correlated equilibrium with payoffs outside the convex hull of Nash equilibrium payoffs by privately recommending play. We find that subjects are reluctant to follow certain recommendations....
