In this paper I scrutinize the impact of employment on time-to-degree in Higher Education. In contrast to the previous literature, I look at different types of working while being enrolled at university. Using the German Socio-Economic Panel (GSOEP), I find that full-time employment and...

We examine the impact of tuition fees for long term students at the University of Konstanz. Applying duration analysis to examine how tuition fees influence when and how students finish their studies in six different majors, we find significant effects with respect to the hazard rates of the...

Many European universities face demands to provide excellent education and to enrol more students at the same time. With scarce financial resources policy makers concentrate on regulations (especially admission policies, tuition fees, and the introduction of competition) to meet the different...

This paper tests the feasibility and empirical implications of a spatial econometric model with a full set of interaction effects and weight matrix defined as an equally weighted group interaction matrix applied to research productivity of individuals. We also elaborate two extensions of this...

I model research quality as the outcome of a CES production technology that uses human capital measured by publication records as inputs. Investigating a sample of scientific publications with two co-authors I show that the CES-complementarity parameter is a function of the age difference of the...

This paper proposes a generational accounting approach to valuating research. Based on the flow of scientific results, a value-added (VA) index is developed that can, in principle, be used to assign a monetary value to any research result and, by aggregation, on entire academic disciplines or...

Despite the prevalence of both competitive forces and patterns of collaboration within academic communities, studies on research productivity generally treat universities as independent entities. By exploring the research productivity of all academic economists employed at 81 universities and 17...

We examine the effect of parenthood on the research productivity of academic economists. Combining the survey responses of nearly 10,000 economists with their publication records as documented in their RePEc accounts, we do not find that motherhood is associated with low research productivity....
