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.

移民、多样性和机构

本文使用 1990 年至 2015 年期间 130 个国家的样本国际移民数据，研究了移民与东道国制度质量之间的关系。我们采用了政治制度的两个复合指标，涵盖了治理的多个维度。为了减少与移民定居模式相关的内生性问题，我们在 2SLS 环境中采用了基于伪重力的仪器。总体而言，我们的研究结果经得起多次稳健性检验，并表明移民对本研究中分析的国家的制度发展水平具有负面和统计上的显着影响。然而，存在很大的异质性，因为在欠发达的东道国，移民的影响似乎更大一些。有趣的是，
