Sichern "Männerberufe" tatsächlich einen besseren Erwerbseinstieg als "Frauenberufe"? In welchem Ausmaß können frauen-bzw. männerdominierte Berufe im Leben junger Menschen erwerbsbiographische Kontinuität stiften? Ausgehend von der Überlegung, dass die Konsequenzen geschlechtstypischer Berufsentscheidungen mit den konkreten wirtschaftsstrukturellen und institutionellen Rahmenbedingungen variieren, ...
Using a sample obtained from a survey conducted in the United States during summer 2002, we study the variables related to observed differences in the rate of entrepreneurial involvement between black and white Americans. We find strong evidence that differences in subjective and often biased perceptions are highly associated with entrepreneurial propensity across these two racial groups. In addition, ...
While previous research found no other variable than corruption to have a negative impact on the growth rate of the elephant populations of African countries, we show that one further significant impact is exerted by "neighbourhood effects". Elephants travel long distances, often crossing borders. Using spatial econometric tools, we find that elephant population changes in one country have a positive ...
We introduce a two-dimensional measure for the heterogeneity of performance within groups. It leads to a much more differentiated description of heterogeneity than alternative measures and it is relatively robust with regard to extreme values of small units ("outliers").
The analysis of motorway renewal costs presented in this paper was driven by two research questions: First, to analyse the economic process of motorway renewal work and to identify whether there exist economies of scale; and second to identify the influence of traffic volume on renewal costs and to derive an estimate of marginal infrastructure costs as part of optimal road user charges. The analysis ...
This paper proposes a simultaneous-equation approach to the estimation of the contribution of transport infrastructure accumulation to regional growth. We model explicitly the political-economy process driving infrastructure investments; in doing so, we eliminate a potential source of bias in production-function estimates and generate testable hypotheses on the forces that shape infrastructure policy. ...
Reliable information on small- and medium-sized enterprises (SMEs) is rare and costly for financial intermediaries. Therefore relationship banking is often considered as the appropriate lending technique. In this paper we offer a theoretical model to analyze relationship banking and the pricing behavior of banks in a Bertrand competition framework with monitoring costs. We show that the lack of reliable ...
