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...

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...

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....

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 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...

When the Soviet Union collapsed a transition process started in Eastern Europe. This included a number of reforms to adapt the educational system to the new requirements of the job market. To assess the educational systems in Eastern Europe, this paper takes a look at the gap in PISA test scores...

We study the effects of random assignment to coeducational and single-sex classes on the academic performance of female high school students. Our estimation results show that single-sex schooling improves the performance of female students in mathematics. This positive effect increases if the...

We present results from a field experiments at Swiss high schools in which we compare the effectiveness of teaching methods in economics. We randomly assigned classes into an experimental and a conventional teaching group, or a control group that received no specific instruction. Both of our...

We study whether early tracking of students based on ability increases migrant-native achievement gaps. To eliminate confounding impacts of unobserved country traits, we employ a differences-in-differences strategy that exploits international variation in the age of tracking as well as student...

We present results from a field experiment at Swiss high schools in which we compare the effectiveness of a classroom experiment against conventional economics teaching. We randomly assigned classes into different teaching environments or a control group. Our results suggest that both teaching...
