In public procurement a temporal separation of award and actual contracting can frequently be observed. In this paper we give an explanation for this institutional setting. For incomplete procurement contracts we show that such a separation may increase efficiency. We show that efficiency can be...

The purpose of this paper is twofold. We first develop a contractarian theory of redistribution. The existence of rules of redistribution is explained without any recourse to the risk-aversion of individuals. Hence, we depart from the standard legitimization of redistribution as fundamental...

The issue of capital tax competition in source-based capital taxes is viewed to be unproblematic if residence-based capital taxation exists. The sustainability, however, of residence-based capital taxation depends on the co-operation of source countries to assist in collecting tax revenues that...

This paper examines information sharing between governments in an optimal taxation framework. We present a taxonomy of alternative systems of international capital income taxation and characterize the choice of tax rates and information exchange. The model reproduces the conclusion of the...

We develop a two-region model where the decentralized provision of spillover goods can be financed by means of taxes or user fees. In order to enforce the fees regions have to invest in exclusion. We show that a decentralized solution tends to be inefficient. There will be over-investment in...

This paper develops a theory of endogenous mutual concern. The mutual concern or the morality of economic agents is seen as a means to reduce the inefficiencies of markets in an environment where the enforcement of property rights is castly. We show that rational agents have an incentive to...

In this paper we analyze the optimal degree of centralization for the supply of public goods. We identify the reliance on an exclusion mechanism as a central feature of the decentralized provision of public goods. An exclusion mechanism induces a contest between users of the public goods who...

In this paper we analyze the structure of contest equilibria with a variable number of agents. First we analyze a situation where the total prize depends on the number of agents and where every single agent faces opportunity costs of investing in the contest. Second we analyze a situation where...
