We study the short- to medium-run effects of starting a career on a fixed-term contract on subsequent fertility outcomes. We focus on the career start since we expect that temporary contracts and their inherent economic uncertainty imply a path dependency which might have spill-over effects on...

Does a high regional concentration of immigrants of the same ethnicity affect immigrant children's acquisition of host-country language skills and educational attainment? We exploit the exogenous placement of guest workers from five ethnicities across German regions during the 1960s and 1970s in...
