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...

We examine the effect of introducing Knightian uncertainty into a simple model of public good provision. We find that uncertainty may reduce the free-rider problem if utility is concave in public goods or there are decreasing returns to scale in the production of public goods. It is possible...

In a small open economy with heterogeneous firms, in which tariffs determine the mass of active firms, the gains from trade liberalization depend positively on the level of firm vertical heterogeneity and negatively on transportation costs. The benefits from temporary protection depend on the...

In a small open economy with heterogeneous firms, in which tariffs determine the mass of active firms, free trade optimality depends positively on the level of firm heterogeneity and negatively on transportation costs. The benefits from temporary protection depend on the level of backwardness:...

Tax earmarking imposes a constraint on government policymaking, and may be desirable if it solves a time-inconsistency problem in tax policy. In a two-period economy, in which the policy decisions regarding taxes, public goods provision, and pollution abatement are taken by a majority-elected...

The paper explores the hypothesis of a double divident from environmental taxation. It is argued that an environmental tax reform, i.e. shifting the burden of taxation away from labour toward the environment can improve environmental quality, boost employment and increase welfare. The 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...
