This paper addresses the existence of Nash equilibria in one-way flow models in a number of different settings. In these models players form costly links with other players and obtain resources from them through the directed path connecting them. We find that heterogeneity in the costs of establishing links plays a crucial role for the existence of Nash networks. The paper also provides conditions ...

We test the hypothesis that rising prices of emission allowances have a stronger impact on wholesale electricity prices than falling prices (asymmetric cost pass-through). Using an autoregressive distributed lag model, we confirm this hypothesis for the German market

The work-incentive, labor-supply, and welfare effects of these policy reforms are analyzed on the basis of a behavioral microsimulation model for Germany. We find that the simulated ...

In Germany, support for families includes diverse types of financial and material aid. These different programs are not aligned and coordinated, but rather stand alone alongside each other and are far from being transparent. This article argues that this situation could be remedied by grouping the various family-related support measures within a single family support agency as a parafiscal institution. ...

Analysis of consumer-related and consumer-generated data is a very important way to measure the success of on-line retailing. The software packages for data analysis have two major shortcomings: (1) solutions are not offered as a service reachable by standard procedures over the Internet, but as isolated standalone applications or ERP system modules; (2) privacy restrictions need to be integrated into ...

Data from the German Socio-Economic Panel Study are used to estimate models of developmental functioning in four critical areas (verbal skills, activities of daily living, motor skills, and social skills) as a function of various measures of weight (including body mass index and obesity) ...

While several European and national studies have dealt with the acceptability of road pricing schemes for passenger transport, only sparse research is available on this issue for freight transport. Against this background, the paper deals with the acceptability of the German road user-charging scheme for heavy goods vehicles by the road haulage industry. It presents the findings of an internet-based ...

In Eastern Germany, wage differentiation between firms has clearly grown, parallel to individual wage differentials. Nevertheless, the wage spread between firms is still much less than in Western Germany. In this paper, a non-parametric decomposition is used to analyze the difference between the wages spread in the two parts of Germany. Only part of the difference can be explained by different economic ...

This paper provides an explanation for the empirically proven relationship between overtime and future benefits. We suggest an internal signaling model, in which a worker signals his value to the employer by supplying unpaid overtime. In our empirical analysis, we examine whether overtime has in fact a signaling component. Variations in collectively bargained hours between industries are exploited, ...
