Billions of dollars are allocated every year to university research. Increased specialisation and international integration of research and researchers has sharply raised the need for comparisons of performance across fields, institutions and individual researchers. However, there is still no...

We study to what degree authors who publish in the five most prestigious journals in economics have previously published there and in which world region they are based. Al­though still high, the concentration of U.S.-based and previously published top-five authors has decreased. This trend is...

Borrowing ideas from the medical sciences, we propose tentative guidelines for reliable causal inferences that cover aspects related to both the study itself and its fit with background knowledge. We argue that the current paradigm in economics tends to put too much emphasis on internal aspects...

William J. Baumol was one of the most prolific economists of his generation, analyzing a broad range of central economic issues addressing real problems of the world. In this essay, we present and critically evaluate Baumol's research contributions in entrepreneurship economics and point to...

We review and evaluate some recent contributions on modeling entrepreneurship within a neoclassical framework, analyzing how and to what extent the fundamental ingredients suggested in the social science literature were captured. We show how these approaches are important in stressing the main...

The increased international exchange and competition in modern economics research has boosted the demand for objective and internationally comparable evaluations of institutions and individual researchers. There exist several plausible measures of research performance, each capturing one or...

We study to what degree authors who publish in the five most prestigious journals in economics have previously published there and in which world region they are based. Although still high, the concentration of U.S.-based and previously published top-five authors has decreased. This trend is...

We provide a model that explains the following empirical observations: i) private ownership is more efficient than public ownership, ii) privatizations are associated with increases in efficiency and iii) the increase in efficiency predates the privatization. The two key mechanisms explaining...

Forward sales is a credible commitment to aggressive spot market bidding, and it mitigates producers' market power in electricity markets. Still it can be profitable for a producer to make such a commitment if it results in a soft response from competitors in the spot market (strategies are...
