Immigration, diversity and institutions
利用130个国家1990-2015年的数据，研究发现移民对东道国的制度质量有显著的负面影响，且这种影响在欠发达国家更强，完全由来自低制度发展国家的移民驱动。
Abstract This paper examines the relationship between immigration and host countries' institutional quality, using international migration data for a sample of 130 countries over the 1990–2015 period. We employ two composite metrics of political institutions, encompassing multiple dimensions of governance. To reduce endogeneity concerns, related to immigrant settlement patterns, we employ pseudo‐gravity‐based instruments in a 2SLS setting. Overall, our findings withstand several robustness checks and suggest that immigration has a negative and statistically significant impact on the level of institutional development of the countries analyzed in this study. However, there is substantial heterogeneity, since the impact of migrants appears to be somewhat stronger in less developed host countries. Interestingly, these findings are entirely driven by migrants stemming from countries displaying low institutional development.
