In this paper we provide estimates of the short-run elasticity of substitution between male and female workers, using data from Italian provinces for the period 1993–2006. Our identification strategy relies on a natural experiment. In 2000, the Italian Parliament passed a law to abolish...

"We study how class size and class composition affect the academic and labor market performance of college students, two crucial policy questions given the secular increase in college enrollment. Our identification strategy relies on the random assignment of students to teaching classes. We find...

This paper estimates the impact of college teaching on students' academic achievement and labor market outcomes using administrative data from Bocconi University matched with Italian tax records. The estimation exploits the random allocation of students to teachers in a fixed sequence of...

This paper contrasts measures of teacher effectiveness with the students’ evaluations for the same teachers using administrative data from Bocconi University. The effectiveness measures are estimated by comparing the performance in follow-on coursework of students who are randomly assigned to...

Little is known about the economic mechanisms leading to the high level of clustering in behavior commonly observed in the data. We present a model where agents can interact according to three distinct mechanisms, and we derive testable implications which allow us to distinguish between the...

In this paper we investigate whether peers' behavior influences the choice of college major, thus contributing to the mismatch of skills in the labor market. Using a newly constructed dataset, we are able to identify the endogenous effect of peers on such decisions through a novel identification...
