Bureaucrats and Public Procurement.

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 game to be played afterward. In the first game the relationship-specific investments of agency and seller are determined, in the second game the decision on the production of the project is taken. In contrast to many other incomplete-contract papers, in our Niskanen setting it is meaningless to write one and only one contract which refers to both investment and production. Welfare-optimal procurement of the project can be attained under relatively weak assumptions; welfare-optimal investments of the seller (and only of the seller) may result under special circumstances; welfare-optimal investments of both agency and seller cannot be reached.

Self-Correcting Mechanisms in Public Procurement: Why Award and Contract Should be Separated

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 increased by post-award, pre-contract negotiations between the award-winning seller and one of the `losing' sellers. Surprisingly, the efficiency gains can be higher if the award is given to a seller with a lower reputation for quality instead of to a seller with higher reputation. Under certain conditions post-award, pre-contract rent-seeking activities also increase efficiency. This is always the case if the procurement agency is corrupt, but may also occur in the case of lobbying.Procurement, Incomplete contracts, lobbying, corruption

The Legal Construction of Membership: Nationality Law in Germany and the United States. CES Germany & Europe Working Papers No. 00.5, 2000

The argument of this paper is that several empirical puzzles in the citizenship literature are rooted in the failure to distinguish between the mainly legal concept of nationality and the broader, political concept of citizenship. Using this distinction, the paper analysis the evolution of German and American nationality laws over the last 200 years. The historical development of both legal structures shows strong communalities. With the emergence of the modern system of nation states, the attribution of nationality to newborn children is ascribed either via the principle of descent or place of birth. With regard to the naturalization of adults, there is an increasing ethnization of law, which means that the increasing complexities of naturalization criteria are more and more structured along ethnic ideas. Although every nation building process shows some elements of ethnic self-description, it is difficult to use the legal principles of ius sanguinis and ius soli as indicators of ethnic or non-ethnic modes of community building

Inefficient R&D in Public Procurement: Negative Consequences of a Separation between Award and Actual Contract

In public procur ement 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, in such a situation it is impossible to find fixed prices which guarantee the achievement of both efficient trade and efficient investment.Procurement, Incomplete Contracts

Contests Among Bureaucrats

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 bureaucrats. This paper characterizes the Nash equilibria in lobbying and shows in which way exogenously fixed bureaucratic incomes induce the same or different lobbying behavior as incentive incomes.bureaucracy, lobbying, contests

Exploratorische Analysen zu Komponenten des Schulerfolgs

Aus der Durchsicht neuerer Forschungsliteratur zum Thema Schulprognose läßt sich ableiten, daß im Gegensatz zur unbestrittenen Bedeutung von kognitiven Tätigkeitsmerkmalen die Relevanz von nicht-kognitiven (z. B. Angst- und Leistungs-)Merkmalen für die Schulleistung nicht klar abzuschätzen ist. In der vorliegenden Untersuchung wurde nun der Vetsuch unternommen, anhand von explorativen Kausalmodellen mit latenten Variablen (LVPLS) die relative Bedeutsarnkeit nichtkognitiver Variablen für den Schulerfolg zu bestimmen. Die anhand einer Stichprobe von 87 Viertkläßlern gewonnenen Befunde unterstreichen die herausragende Relevanz kognitiver Merkmale, deuten jedoch auch darauf hin, daß die Rolle von Angsrkomponenten und Leistungsmotivkennwetten aufgrund ihrer vorwiegend indirekten Einflußnahme nicht unterschätzt werden darf. Angesichts der immer noch defizitären Theorieentwicklung im Bereich der Schulerfolgsprognose wird dafür plädiert, hier weiterhin gezielt mit explorativen Modellen zu arbeiten

Anarchy, Efficiency and Redistribution

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 insurance and interpret it as stemming from a principle of reciprocity in trade. The second purpose of the paper is to develop a theory of institutions that implement optimal allocations. We depart from the assumption of an exogenous enforcement of constitutional rules. Hence, the self-enforcement of constitutional rules is crucial for the implementability of allocations. This approach implies that there is no allocative difference between constitutional and ordinary rules. What makes constitutions different from ordinary rules is their potential ability to create a focal point that conditions the expectations of individuals on a certain equilibrium strategy. Hence, constitutions help to solve coordination problems, not cooperation problems.Anarchy, Constitution, Redistribution
