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...

Urban traffic congestion is recognised as a major problem by most people in world cities. However, theimplementation of congestion reducing measures on a wide scale eludes most world cities suffering fromtraffic congestion, as many oppose the notion of road pricing and despite economists and...

Pigouvian taxes are typically imposed in situations where there is imperfect knowledge on the extent of damage caused by a producing firm. A regulator imposing imperfectly informed Pigouvian taxes may cause the firms that should (should not) produce to shut down (produce). In this paper we use a...

"Inspired by the Coase (1937) theory of the firm, we analyze the performance of Healy, Palepu, and Ruback (1992) sample of merged firms over a ten-year period using a managerially controlled efficiency measure, data envelopment analysis (DEA). Our individual, firm-level, year-by-year analyses...

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...
