In the case where a given demand increase over a finite time span is known and exceeds current production capacities, a marginal cost analysis can provide decision criteria for work-force adjustments. Using the marginal costs of hiring new workers and for various periods of overtime as a basis,...

Professionalität im Management von kleinen und mittleren Vereinen weist einen deutlichen Zusammenhang mit ihrer Ressourcenlage und dem Grad ihrer Zielerreichung auf. Am Beispiel von Schweizer Sportvereinen lässt sich zeigen, dass sich die erfolgreicheren Vereine insbesondere durch eine...

Many empirical papers tested the theoretical predictions of Helpman, Melitz and Yeaple (HMY, 2004) which sorts firms at different internationalization states according to their productivity levels. While these papers ignore the fact, that the theoretical predictions of HMY only apply to firms...

In this paper, we evaluate the R&D enhancing effects of two large public grant schemes aiming at encouraging the performance of firms organized in clusters. These are Germany's well known BioRegio and BioProfile contests for which we compare the research performance of winning regions in...

A comparison is made between the bid-ask spreads of 30 high volume German stocks traded on IBIS and 30 high volume US stocks traded on Nasdaq. IBIS and Nasdaq are best described as agency and dealer auction markets, respectively. On average, the market spread for these IBIS and Nasdaq stocks is...

We consider stationary Poisson line processes in the Euclidean plane and analyze properties of Voronoi tessellations induced by Poisson point processes on these lines. In particular, we describe and test an algorithm for the simulation of typical cells of this class of Cox–Voronoi...
