The recent refugee surge has brought attention to the macro-critical policy issue of migration, including speculations that migration can be an unfavorable phenomenon for the receiving economies. A careful examination of the impact of migration on host economies is thus critical. Focusing on the economic impact, most of the academic discussion has centered on the effect of migration on labor markets and public finances. Much less is known about the long-term impact of immigration on the GDP per capita (or the standard of living) of host economies. This note makes three contributions to estimating this impact: it uses a restricted sample of advanced economies rather than a mixed sample of higher- and lower-income host countries, it examines whether the GDP per capita impact varies for different skill levels of migrants, and it goes beyond the aggregate impact of migration on GDP per capita to examine how broadly gains in this regard are shared across the population. In particular, it examines whether migration impacts the income levels of those both at the top and at the bottom of the earnings distribution, or whether gains are instead concentrated in a small group of high earners. It finds that immigration significantly increases GDP per capita in advanced economies, that both high- and lower-skilled migrants can raise labor productivity, and that an increase in the migrant share benefits the average income per capita of both the bottom 90 percent and the top 10 percent of earners, suggesting the gains from immigration are broadly shared.

After close to two decades of strong economic activity, overall growth in sub-Saharan Africa decelerated markedly in 2015–16 as the largest economies experienced negative or flat growth. Regional growth started recovering in 2017, but the question remains of how trends in the economies stuck in low gear will spill over to the countries that have maintained robust growth. This note illuminates the discussion by identifying growth spillover channels. The focus is on trade, banking, financial, remittance, investment, fiscal, and security channels, which are the most prominent and most likely to transmit growth trends across borders. In addition to bringing together findings from a broad array of existing research, the note identifies countries that are the most likely sources of regional spillovers and those that are most likely to be impacted, and provides estimates for the size of these channels. It finds that intraregional trade and remittance flows are an important channel for growth spillovers, while banking channels are less important but will remain a risk going forward. Finally, the note documents other important spillover channels through financial markets contagion, revenue-sharing arrangements in fiscal unions, commodity-pricing policies, corporate investment, and forced migration. The main takeaway is that the level of interdependence among sub-Saharan countries is higher than is generally assumed. Consequently, there is a need for additional emphasis on regional surveillance and spillover analysis, along with traditional bilateral surveillance.

In the face of sharply lower oil prices and geopolitical tensions and sanctions, economic activity in Russia decelerated in late 2014, resulting in negative spillovers on Commonwealth of Independent States (CIS) and, to a lesser extent, on Baltic countries. The spillovers to eastern Europe have been limited. The degree of impact is commensurate with the level of these countries’ trade, remittances, and foreign direct investment (FDI) links with Russia. So far, policy action by the affected countries has focused on mitigating the immediate consequences of spillovers.
