Addressing unauthorized immigration is controversial. Countries have adopted a variety of legalization programs, ranging from temporary visa programs to naturalization. Research in the US focused on past amnesty programs finds improved labor market outcomes for newly legalized immigrants....

In common anti-immigrant rhetoric, concerns are raised that immigrants bring diseases with them to the host country that threaten the health of the resident population. In reality, extensive empirical research over several decades and across multiple regions and host countries has documented...

Does the politico-economic system affect preferences for immigration? In this study, I show that individuals exposed to life under state socialism have formed and persistently hold different attitudes toward immigration. By exploiting the division and reunification of Germany, I estimate the...
