Immigration and work schedules: Theory and evidence

We develop a theoretical framework to analyze the effects of immigration on native job amenities, focusing work schedules. Immigrants have comparative advantage in production at, and lower disamenity cost for nighttime work, which leads them disproportionately choose employment. Because day night tasks are imperfect substitutes, relative price increases as their supply becomes relatively more scarce. provide empirical support our theory. Native workers local labor markets that experienced higher rates likely shifts receive compensating differential work.
