Using matched employer-employee data, we identify the determinants of immigrants' earnings in the Portuguese labor market. Results previously reported for countries with a long tradition of hosting migrants are also valid in a new destination country. Two-thirds of the gap is attributable to...

This paper investigates the question whether long-term human capital outcomes are affected by the duration of maternity leave, i.e. by the time mothers spend at home with their newborn before returning to work. Employing RD and difference-in-difference approaches, this paper exploits an...

The question of how technology affects learning has been at the center of recent debates over educational inputs. In 1994, the Israeli State Lottery sponsored the installation of computers in many elementary and middle schools. This program provides an opportunity to estimate the impact of...
