This paper analyzes peer effects among university scientists. Specifically, it investigates whether the number of peers and their average quality affects the productivity of researchers in physics, chemistry, and mathematics. The usual endogeneity problems related to estimating peer effects are...

A new way of constructing efficient semiparametric instrumental variable estimators is proposed. The method involves the combination of a large number of possibly inefficient estimators rather than combining the instruments into an optimal instrument function. The consistency and asymptotic...

Differences in promotion across genders are still prevalent in many occupations. Recent work based on experimental evidence indicates that women participate less in or exert lower effort during contests. We exploit the unique features of the promotion system for French academics to look at...

Using a new data set that allows us to analyze precisely the research output in all fields of science, we show that the gap in scientific performance between Europe, especially continental Europe, and Anglo-Saxon countries, especially the USA, is large. We measure research quality by the number...

Individuals and business owners engage in an increasingly complex array of financial decisions that are critical for their success and well-being. Yet a growing literature documents that in both developed and developing countries, a large fraction of the population is unprepared to make these...

I investigate the effect of faculty quality on Ph.D. student outcomes. To address the endogeneity of faculty quality I use exogenous variation provided by the expulsion of mathematics professors in Nazi Germany. I find that faculty quality is a very important determinant of short and long run...
