Abstract: This note revisits the role of migrant social networks as determinants of bilateral-migration flows. We do so using a new database that covers about 190 world countries and features more accurate estimates of bilateral flows than those employed so far. Our battery of gravity- model exercises show that the impact of social networks is consistent and significant over different specifications, and in line with previous estimates. Furthermore, in presence of migrant networks at destination, geographical distance counts in explaining the absence of a migration corridor only when such networks have very small sizes.
