We consider a two-period overlapping generations model in which individual voters differ by age and by productivity, In such a setting, a redistributive Pay-As-You-Go system is politically sustainable, even when the interest rate is larger than the rate of population growth. The workers with...

The purpose of this paper is to survey the theoretical literature on wealth transfer taxation. The focus is normative: we are looking at the design of an optimal tax structure from the standpoint of both equity and efficiency. The gist of this survey is that the optimal design closely depends on...

This paper deals with a Niskanen type of public-procurement agency. It is shown that the procurement game should be separated into an investment game and a project game, the first game to be played before nature determines the actual realizations of benefit and costs of the project, the second...

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

This paper deals with double lobbying: several bureaucrats participate in joint lobbying to get a high total departmental budget, but they also engage in antagonistic lobbying to reap as high a share of the total budget as possible. The antagonistic lobbying constitutes a contest among the...

This paper models privatization as a cooperative game between the government, a trade union and the private shareholders. These players know that privatization increases the efficiency of a firm, but only the management of the firm knows the exact value of the relevant productivity-increasing...

Compared with the traditional public-finance approach of a monolithic fully informed planner, earmarking of taxation is less likely to be optimal if a principal-agent setting is considered, where taxing and spending are performed by two separate agents which are monitored by the parliament. We...

In public procurement a temporal separation between award and actual contract allows private entrepreneurs who did not get the award to sue to become contractor. Hence, not only the award-winning entrepreneur, but also the losers will engage in relationship-specific investments. Unfortunately,...

It is often argued that implicit taxation on continued activity of elderly workers is responsible for the widely observed trend towards early retirement. In a world of laissez-faire or of first-best efficiency, there would be no such implicit taxation. The point of this paper is that when...
