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:...

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...

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...

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...

In the Crawford-Sobel (uniform, quadratic utility) cheap-talk model, we consider a simple mediation scheme (a communication device) in which the informed agent reports one of the N possible elements of a partition to the mediator and then the mediator suggests one of the N actions to the...

We consider a Battle of the Sexes game with incomplete information and allow cheap talk regarding players' private information before the game is played. We prove that the unique fully revealing symmetric cheap talk equilibrium has a desirable coordination property. Such coordination can also be...

We analyze the Hotelling-Downs model of a winner-take-all elections with sequential entry where n 2 'office-seeking' candidates with privately known qualities arrive in an order to announce platform commitments and voters receive partially informative exogenous signals about quality of each...
