Sportwetten werden in Deutschland in der Marktordnung eines Veranstaltungsmonopolsder öffentlichen Hand vergleichbar den Lotterien reguliert. Das Monopol wurde vom Bundesverfassungsgerichtim März 2006 in der bisherigen Form als rechtlich unzulässiges Fiskalmonopol verworfen. Demnach ist...

This paper examines employer-to-employer mobility by describing theindividual wage trajectories along the working career. The model, whichis designed to introduce optimal between-firm mobility, is based on thesearch, the matching, and the human capital theory. It is emphasizedthat hopping from...

This paper proposes a model that links households and firms, as usual, by markets forfactors and goods and, additionally, by a banking sector that channels households’funds to firms and eliminates idiosyncratic risk. In equilibrium, agency costs and taxbenefits of corporate debt are equalizing...

This paper presents a new algorithm for the dynamic Multi-Level Ca-pacitated Lot Sizing Problem with Setup Carry-Overs (MLCLSP-L). TheMLCLSP-L is a big-bucket model that allows the production of any num-ber of products within a period, but it incorporates partial sequencing of theproduction...

In this paper, we analyze the performance of call centers of financial serviceproviders with two levels of support and a time-dependent overflow mechanism.Waiting calls from the front-office queue flow over to the back office, if a waiting-timelimit is reached and at least one back-office agent...

Im Referentenentwurf zum BilMoG wird die Untergrenze der Herstellungskosten neu gefasst,in die neben den Einzelkosten nun auch die variablen Gemeinkosten einzubeziehen sind. DerBeitrag klärt zunächst, wie variable Gemeinkosten aus Sicht der Kostenrechnung zu ermittelnsind. Anschließend wird...

This paper presents an optimization-based solution approach for the dynamicmulti-level capacitated lot sizing problem (MLCLSP) with positive leadtimes. The key idea is to solve a series of mixed-integer programs in an iterativefix-and-optimize algorithm. Each of these programs is optimized over...

This paper provides evidence on the hypothesis that many behavioral finance patterns are sodeeply rooted in human behavior that they are difficult to overcome by learning. We test thison a target group which has undoubtedly very strong incentives to learn efficient behavior,i.e. fund managers....

There are robust gender differences in the domains of risk taking, overconfidence and competitionbehavior. However, as expertise tends to level these differences, we ask whether financialexperts still show gender dissimilarities in their domains of decision making? We analyzesurvey responses of...

This paper presents a linear programming approach to analyze and optimizeow lines with limited buer capacities and stochastic processing times. The basic ideais to solve a huge but simple linear program that models an entire simulation run of amulti-stage production process in discrete time, to...
