Abstract: | This note revisits the role of migrant social networks (MSNs) as determinants of bilateral migration flows. We do so using two alternative databases, covering about 190 world countries for the period 1960–2000. In line with previous estimates, we consistently find a significant, positive, impact of MSNs at destination. We also find that such an impact decreases very slowly as the year when MSNs are observed is farther back in the past. We also find that geographical distance is becoming less and less important over time but significantly explains the absence of a migration corridor only when MSNs at destination have very small sizes. |
