In empirischen und theoretischen Untersuchungen wird die Rolle von Verträgen für das Zustandekommen von ökonomischen Transaktionen auf Arbeitsmärkten betont. Da die Investitionstätigkeit in Sach- und Humankapital sowie in Forschung und Entwicklung häufig spezifisch erfolgt, ist es...

No one would argue that the economy in the United States has been faltering in recent years; due in part to global factors, and even with stimulus plans offered by the Federal Government, there is increased burden on states to find forms of revenue. More and more, states must compete not only...

The Maschler-Perles solution is the unique bargaining solution which is superadditive and satisfies the usual covariance properties. We provide two proofs for superadditivity that do not rely on the standard traveling time.

A cephoid is an algebraic ("Minkowski") sum of finitely many prisms in R^n. A cephoidal game is an NTU game the feasible sets of which are cephoids. We provide a version of the Shapley NTU value for such games based on the bargaining solution of Maschler-Perles.

Die Staatsverschuldung vieler industrialisierter Länder hat seit Anfang der siebziger Jahre drastisch zugenommen. Zwar waren die meisten Länderhaushalte in der Zeit vom Ende des Zweiten Weltkriegs bis in die frühen siebziger Jahre durch eine deutliche Abnahme der Staatsverschuldung...

This dissertation contributes to the theoretical understanding of the determinants and consequences of productive government activity for the economic performance of a country’s economy. Chapter 2 gives a comprehensive survey of the recent theoretical literature on the link between productive...

Existing theoretical literature fails to explain satisfactorily the differences between the pay of workers that are covered by collective agreements and others who are not. This study aims at providing a model framework which is amenable for an analysis of this issue. Our general-equilibrium...

It is given a brief overview over the experimental results in ultimatum games with complete and incomplete information, especially considering fairness. Following theories which model different fairness considerations are presented. The main part extends the Double Auction model by the inequity...
