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...

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...

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 a variant of the canonical public good provision model, as proposed by Borgers and Postl (2009). In this set up, we fully characterize the set of budget-balanced dominant strategy deterministric mechanisms, which are simple threshold rules. For...

We study strategy-proof decision rules in the variants of the canonical public good model proposed by Borgers and Postl (2009). In this setup, we fully characterize the set of budget-balanced strategy-proof deterministic mechanisms, which are simple threshold rules. For smooth probabilistic...

We study procurement procedures that simultaneously determine specification and price of a good. Suppliers can offer and produce the good in either of two possible specifications, both of which are equally good for the buyer. Production costs are interdependent and unknown at the time of...

For duopoly models, we consider the notion of weak correlation using simple symmetric devices that the players choose to commit to in equilibrium. In a linear duopoly game, we prove that Nashcentric devices involving a sunspot structure are simple symmetric weak correlated equilibria. Any small...

We study both theoretically and experimentally the complete set of Nash equilibria of a classical one-dimensional, majority rule election game with two candidates, who might be interested in power as well as in ideology, but not necessarily in the same way. Apart from obtaining the well known...

We consider a Battle of the Sexes game with two types, High and Low, for each player and allow cheap talk regarding players' types before the game. We prove that the unique fully revealing symmetric cheap talk equilibrium exists for a low range of prior probability of the High-Type. This...
