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...

For pay-as-you-go financed pension systems, claims may be calculated according to individual contributions (income) or the number of children of a family. We analyse the optimal structure of these parameters in a model with endogenous fertility. It is shown that for both structural determinants...

From the point of view of institutional economics, property rights are an instrument to shape individual incentives efficiently. For the case of a Tullock contest with endogenously determined rent, I analyze the circumstances under which perfectly secure property rights emerge in an economy...

In this paper we analyze the structure of contest equilibria with a variable number of individuals. 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...

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...

We analyze a model with two countries that are linked by an integrated capital market. Fertility, and thus population growth, is endogenously determined by households. Our analysis proceeds in three steps: First, we characterize an optimal intertemporal and interregional allocation in a model...

In a simple model based on political support approach, we show that poor and less egalitarian societies may impose a lower tax rate contrary to the prediction of the median voter approach. This is consistent with the available empirical findings. In the framework developed in this paper, the...
