This paper investigates how exposure to higher-achieving male and female peers in university affects students’ major … choices and labor market outcomes. For identification of causal effects, we exploit the random assignment of students to …

In particular, low-persistence students benefit from highly …-persistent peers without devoting additional efforts to studying. However, highly-persistent students are not affected by the …

This paper develops a framework for the quantitative analysis of individual income dynamics, mobility and welfare …. Individual income is assumed to follow a stochastic process with two (unobserved) components, an i.i.d. component representing … measurement error or transitory income shocks and an AR(1) component representing persistent changes in income. We use a tractable …
