How Robust Is the Evidence on the Impact of Diasporas on Institutional Quality in Home Countries?

This paper conducts a robustness analysis of the impact of diasporas on institutional quality in home countries. Using the Database on Immigrants in OECD Countries (DIOC), we attest that the home country institutional development role of diasporas found in the literature is robust to modifications in terms of the dataset, the measurement of diasporas and the instrumental variable procedures used in our cross‐sectional and panel analyses. The novelty of this paper is that we take the heterogeneity of diasporas into account in terms of their distribution across host countries, their duration of stay, and the level of development of their home countries. As in earlier literature, we find robust evidence that diasporas enhance institutional quality in home countries. We also find that the intensity of the diffusion of advanced institutions from developed host countries to home countries through the international migration channel is weaker with diasporas characterized by shorter average duration of stay and with diasporas from developing home countries. However, this diffusion effect is not significantly related to the distribution of diasporas across OECD host countries.
