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 ...

This paper investigates the association between obesity and skill attainment in early childhood (aged 2-3 years). 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) ...

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

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. ...

It surveys previous historical experiences and empirical findings including the recent Eastern enlargements. The determinants of migration before and after the 2004 enlargement and in the EU15 and EU10 countries ...

In the development literature, there exists no systematic study of external borrowing in post-conflict countries. We address this gap by analyzing statistical and case study evidence from three African countries. We find that many war-affected countries face rising debt arrears and deteriorating relations with creditors. Rebuilding trust between lenders and borrowers is hence a crucial but often slow ...

The paper investigates the role of human capital on immigrants' ethnic ties towards their home and host countries. Pre-migration characteristics dominate ethnic self-identification. Human capital acquired in the host country does not affect the attachment to the receiving country

This paper presents a model of the European natural gas supply, GASMOD, which is structured as a two-stage-game of successive natural gas exports to Europe (upstream market) and wholesale trade within Europe (downstream market) and which explicitly includes infrastructure capacities. We compare three possible market scenarios: Cournot competition in both markets, perfect competition in both markets, ...

Turning unemployment into self-employment has become a major focus of German active labour market policy (ALMP) in recent years. If effective, this would not only reduce Germany's persistently high unemployment rate, but also increase its notoriously low self-employment rate. Empirical evidence on the effectiveness of such programmes is scarce. We evaluate the effectiveness of two start-up programmes ...
