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...

We consider a risk averse entrepreneur who approaches a diversified venture capitalist (VC) for financing of a project with positive potential return. We develop several models that capture key features of the venture financing, including staged investment, VC oversight costs and agency...

Insurance contracts are frequently modelled as principal–agent relationships. The purpose of this paper is to examine the interaction between differential bargaining power and the efficiency of insurance contracts. The analysis is undertaken in a framework of state-contingent production, which...

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.

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...

Diese Arbeit betrachtet menschliches Verhalten auf elektronischen M?rkten. In diesem Zusammenhang wurden zwei Experimente durchgef?hrt, die das Auction Fever in Holl?ndischen Auktionen sowie das menschliche Risikoverhalten im sehr hohen Wahrscheinlichkeitsbereich n?her untersuchen. Im Experiment...

We model EU countries? bank ratings using financial variables and allowing for intercept and slope heterogeneity. We find that country-specific factors (in the form of heterogeneous intercepts) are a crucial determinant of ratings. Whilst ?new? EU countries typically have lower ratings than...
