Do immigrants squeeze natives out of bad schedules? Evidence from Italy

This paper documents the effect of immigrant concentration on natives' work schedules. I show that immigrants are more likely to work at non-standard hours (i.e. evenings, nights and Sundays) and that a higher proportion of immigrants in the local labor market is associated with a lower probability of employed natives working non-standard shifts. Results are strongest in sectors and occupations that are more accessible to immigrants. In particular, I find that a 1 standard deviation increase in the foreign population residing in a province is associated to a 4% reduction in the natives' likelihood of working non standard hours.
