International migration is an important channel of material improvement for individuals and their offspring. The movement of people across country borders, especially from less developed to richer countries, has a substantial impact in several dimensions. First, it affects the migrants themselves by allowing them to achieve higher income as a result of their higher productivity in the destination country. It also increases the expected income for their offspring. Second, it affects the destination country through the impact on labor markets, productivity, innovation, demographic structure, fiscal balance, and criminality. Third, it can have a significant impact on the countries of origin. It may lead to loss of human capital, but it also creates a flow of remittances and increases international connections in the form of trade, FDI, and technological transfers. This paper surveys our understanding of how migration affects growth and inequality through the impact on migrants themselves as well as on the destination and origin countries.
Remitances are an important source of external financing in low- and middle-income countries. This paper uses the gravity model to analyze remittance flows in Russia and Caucasus and Central Asia (CCA) countries. Standard gravity determinants, such as GDP in sending and recieiving countries, bilateral distance, existence of common borders and common official language, fit remittance flows well. Remittances also react to inflation and exchange rate movements in recipient countries to sustain their purchasing power. In line with the altruism hypothesis, remittances flow to countries with higher age dependency ratio. Remittances are countercyclical and help stabilize outputs in recipient countries. However, global shocks resulting in sharp output losses of sending countries would lead to large volatility and decline of remittance inflows in recipient countries. The results of the analysis can be used to assess the impact of the COVID-19 shock on projected remittance flows into CCA.
