Male physicians outearn women by 13% at the outset of their careers and by 28% eight years later. Conflicting evidence on the existence of a wage gap in medicine stems from the earnings measure used: hourly earnings versus yearly earnings controlling for hours worked.

This paper extends previous results on the equality of OLS and GLS. We give conditions under which GLS based on two different variance matrices gives the same estimate, and also conditions under which GLS equals a GMM estimator.

In this paper, we consider a model where producers set their prices based on their prediction of the aggregated price level and an exogenous variable, which can be a demand or a cost-push shock. To form their expectations, they use OLS-type econometric learning with bounded memory. We show that...

Migrant scientists outperform domestic scientists. The result persists after instrumenting migration for reasons of work or study with migration in childhood to minimize the effect of selection. The results are consistent with theories of knowledge recombination and specialty matching.

The long run effect of migration solely by unskilled workers is that skilled workers in the home country acquire additional human capital yet their share in the country’s workforce falls. Consequently, the country’s average level of human capital is lowered.

Using the recently released UK Household Longitudinal Study we examine whether the raising of the school leaving age in 1972 had a permanent impact on earnings for individuals in their early 50s.

Subjects who overestimate their performance in experimental tasks unrelated to travel are less willing to insure against failing in the task and also less inclined to buy travel insurance. This suggests intrinsic optimism influences insurance demand and diminishes adverse selection.

This paper analyzes anonymous job applications of Ph.D. economists in the academic job market. We use data on interview invitations from a randomized experiment at a European-based research institution. Results show that the underrepresented gender was hurt by anonymous applications.

The academic labor market rewards idea splitting, where researchers publish several short articles rather than one long one. There is a significant positive effect on salary from publishing more articles, conditional on the total number of quality-adjusted pages ever published.

We show in a laboratory experiment that the same method of group induction carries different behavioral consequences. These heterogeneous treatment effects can be directly related to the quality of the relationship established between the subjects. Our results indicate the importance of...
