Economic research on migration tends to focus on workers, labour markets, or communities in receiving countries. However, labour migration and earnings could have important impacts on migrants’ home countries. This column explores these effects by focusing on circular migration from Malawi to South Africa in the 1960s and 1970s. Malawian districts that had the greatest exposure to migration shocks have better educated workers, even three decades later. These findings point to potential ‘brain gain’ effects for sending communities.

For the past few decades, the growth of industrialised economies has been remarkably balanced. This column suggests that such balanced growth results from schooling levels increasing over time. When capital and schooling are sufficiently complementary, increases in schooling offset the effect of capital deepening on the capital share and ensure that growth remains balanced.
