Mass immigration

Quality of institutions

A 2015 study finds "some evidence that larger immigrant population shares (or inflows) yield positive impacts on institutional quality. At a minimum, our results indicate that no negative impact on economic freedom is associated with more immigration." Another study, looking at the increase in Israel's population in the 1990s due to the unrestricted immigration of Jews from the Soviet Union, finds that the mass immigration did not undermine political institutions, and substantially increased the quality of economic institutions. A 2017 study in the British Journal of Political Science argued that the British American colonies without slavery adopted better democratic institutions in order to attract migrant workers to their colonies. A 2018 study fails to find evidence that immigration to the United States weakens economic freedom. A 2019 study of Jordan found that the massive influx of refugees into Jordan during the Gulf War had long-lasting positive effects on Jordanian economic institutions.
