This paper analyzes the influence of child health and maternal physical and mental health on female labor force participation after childbirth in Germany. Our analysis is based on data from the German Socio-Economic Panel (SOEP) study, which enables us to measure child health based on the occurrence of severe health problems including mental and physical disabilities, hospitalizations, and preterm ...

This paper explores insights about marginal airport costs that can be gained by analysing labour inputs and their variability. Based on hourly cost and traffic data for the airport of Helsinki, a multivariate time series approach is used incorporating correlated error terms to account for random shocks such as delays. We found for most airport services a linear relationship between labour input and ...

This paper examines how electronic procurement influences firms' sourcing strategy. The relationship between the technology choice in a vertical structure is illustrated with respect to its impact on the coordination cost and the competition between suppliers. Hypotheses are tested using data from the e-Business W@tch survey. Assessing the relationship between the effect of electronic procurement on ...

This paper investigates whether small businesses face financial constraints that affect their survival. A model of moral hazard is developed in which financial constraints arise endogenously. The model predicts that higher private assets relax financial constraints and have a positive effect on the firm's probability of survival. The empirical analysis confirms that the entrepreneur has a higher propensity ...

[An erratum to this article can be found at http://dx.doi.org/10.1007/s10734-009-9271-4 ]. - School education in Germany is under the responsibility of the federal states and as a consequence average grades differ widely across regions. Since school leavers apply nationwide for admission to university, regional provenance may thus matter a lot for the success probability in the admission process. Using ...

About a decade ago the German Science Council requested a strengthening of academic research at the German economic research institutes to improve the academic foundation of policy advice - the traditional task of the institutes. Based on publications in SSCI journals, research output has since then improved remarkably in scope and quality and has involved an ever rising number of scholars within the ...

Strategic role is connected to autonomy and intra-organisational relationships and the mandates given to the subsidiary.

We apply the EMF 23 study design to simulate the effects of the reference case and the scenarios to European natural gas supplies to 2025. We use GASMOD, a strategic several-layer model of European natural gas supply, consisting of upstream natural gas producers, traders in each consuming European country (or region), and final demand. Our model results suggest rather modest changes in the overall ...

The increase in liquefied natural gas trade has accelerated the integration of previously segmented markets in North America, Europe, and Asia. This paper provides evidence on the integration of the transatlantic natural gas market; it thus complements other papers in the EMF 23 study that focus on prices and international natural gas trade. We test the theoretical proposition that in integrating markets ...

This paper presents results of simulating a more collusive behavior of a group of natural gas producing and exporting countries, sometimes called GASPEC. We use the World Gas Model, a dynamic, strategic representation of world gas production, trade, and consumption between 2005 and 2030. In particular, we simulate a closer cooperation of the GASPEC countries when exporting pipeline gas and liquefied ...
