The effects of immigration on economic outcomes for native workers have been widely investigated. At the same time, little is known about the effects of immigration on native job quality and working conditions.

Several studies document that working late at night or not taking breaks over the weekend is associated with negative health outcomes, less time spent with family and friends, less marital stability, and negative effects on children's well being. In particular, working nonstandard hours has been shown to be associated with negative health outcomes including chronic fatigue, a higher probability of accidents, anxiety, depression, hypertension, obesity, ischemic heart disease, and breast cancer.

This evidence suggests that we cannot neglect nonwage effects when analyzing the overall impact of immigration on the native labor market.

In previous work using Italian data, I showed that immigration is associated with a lower probability of employed natives working non‐standard shifts. I am currently working on two projects analyzing similar effects on working condition and health in the US and Germany.

• In “Immigration and Schedules: Theory and Evidence” (joint with Timothy N. Bond, Purdue University) we investigate whether an increased presence of immigrants in US local labor markets affects the allocation of working schedules across workers. We provide a theoretical model to analyze the effects of immigration on working shifts and test its prediction using US data.
• In “Immigration and Health: Evidence from the German Socio-Economic Panel” (joint with Fabrizio Mazzonna, University of Lugano), we discuss whether and why immigrants in Germany are more likely to sort in jobs characterized by worse working conditions and then investigates how this job sorting affects immigrants’ and natives’ health. The ultimate goal of the paper is to attempt a more comprehensive analysis of the effects of immigration on the overall welfare of natives.
