Experimental evidence from public good games with punishment suggests that punishment works when subjects assign it fairly by sanctioning non-cooperators. This paper reports an experiment in which punishment is assigned unfairly in the sense that it is not linked to individual behaviour and is...

The endogeneity of equilibrium strategies makes modelling uncertainty about the behaviour of other economic players difficult. Recent developments in decision and game theory offer an opportunity to include strategic uncertainty as an explanatory variable in economic analysis. This paper...

In the Crawford-Sobel (uniform, quadratic utility) cheap-talk model we allow for mediation in which the informed agent reports one possible element of a partition to a mediator (a communication device) and then the mediator suggests an action to the uninformed decision-maker according to the...

If an inspector is work averse and his effort spent on investigating reports is not observable this creates a moral hazard problem whenever there is an imperfect monitoring technology. This problem arises because the organization can not distinguish between an inspection that doesn't find...

We study dominant strategy implementation in the compromise setting of Borgers and Postl (2006), in which two agents have to choose one of three mutually exclusive alternatives. The agents' ordinal rankings of these three alternatives are commonly known among them, and they are diametrically...

This paper introduces E-capacities as a representation of beliefs which incorporates objective information about the probability of events. It can be shown that the Choquet integral of an E-capacity is the Ellsberg representation. The paper further explores properties of this representation of...

For duopoly models, we analyse the concept of coarse correlated equilibrium using simple symmetric devices that the players choose to commit to in equilibrium. In a linear duopoly game, we provice that Nash-centric devices, involving a sunspot structure, are simple symmetric coarse correlated...
