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...

Allokationsverfahren zur Vergabe von Zutrittslizenzen an Marktneulinge differieren hinsichtlich mehrerer Aspekte. Einer davon ist die Veröffentlichung der vom Regulierer im Lizenzvergabeverfahren gesammelten Informationen. Der Autor untersucht den Einfluss der Informationsweitergabe auf die...

This thesis contributes to the literature by providing new insights into the patterns and market implications of insider trading. The inferences presented here are based on the insider trading reports filed with the Polish Securities and Exchange Commission and the New Zealand Exchange. First,...

While advance booking programs have been shown to be effective for …firms to manage uncertain demand, the effectiveness of such programs is unclear when supply, demand, and price risks are present in a supply chain. Motivated by an advance booking program for managing these three types of...

We investigate the innovation rate under the impact of business cycles to understand R&D activities and to derive implications for public policies. Combining price competition and endogenous market structure with the framework of dynamic game, we study the Markov perfect equilibrium where...

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...
