Workers' remittances have become a major source of financing for developing countries and are especially important in Latin America and the Caribbean, which is at the top of the ranking of remittance receiving regions in the world. While there has been a recent surge in analytical work on the topic, this book is motivated by the large heterogeneity in migration and remittance patterns across countries and regions, and by the fact that existing evidence for Latin America and the Caribbean is restricted to only a few countries, such as Mexico and El Salvador. Because the nature of the phenomenon varies across countries, its development impact and policy implications are also likely to differ in ways that are still largely unknown. This book helps fill the gap by exploring, in the specific context of Latin America and Caribbean countries, some of the main questions faced by policymakers when trying to respond to increasing remittances flows. The book relies on cross-country panel data and household surveys for 11 Latin American countries to explore the development impact of remittance flows along several dimensions: growth, poverty, inequality, schooling, health, labor supply, financial development, and real exchange rates.

In this paper we survey the recent literature assessing the development impact of international migrant remittances. We begin by arguing that international migration should be fully incorporated in ongoing debates on the impact of globalization. We show that, despite methodological challenges, there is an emerging body of evidence suggesting that migrant remittances can have an important impact on development and household welfare. Remittances appear to help in poverty reduction, accumulation of human capital, investment and saving. Finally, we offer an account of existing policies and recommendations to facilitate remittance flows and to take advantage of their developmental potential.

Migrants have long faced unwarranted constraints to sending money to family members and relatives in their home countries, among them costly fees and commissions, inconvenient formal banking hours, and inefficient domestic banking services that delay final payment to the beneficiaries. Yet such remittances are perhaps the largest source of external finance in developing countries. Officially recorded remittance flows to developing countries exceeded US$125 billion in 2004, making them the second largest source of development finance after foreign direct investment. This book demonstrates that governments in developing countries increasingly recognize the importance of remittance flows and are quickly addressing these constraints.

International migration, the movement of people across international boundaries to improve economic opportunity, has enormous implications for growth and welfare in both origin and destination countries. An important benefit to developing countries is the receipt of remittances or transfers from income earned by overseas emigrants. Official data show that development countries' remittance receipts totaled 160 billion in 2004, more than twice the size of official aid. This year's edition of Global Economic Prospects focuses on remittances and migration. The bulk of the book covers remittances.

We propose a simple macroeconomic model with input-output sectoral linkages based on Acemoglu et al. (2016) to quantify how changes in aggregate demand due to additional income from household’s remittances propagates through the network of input-output linkages in Sub-Saharan African countries. We first propose two network centrality measures to assess the role of some sectors as key input providers in the economy. Then, we use these measures to quantify the effect of sectoral linkages on sectoral and total output following an increase in remittances inflows. Our empirical results suggest that the effects of remittances on recipient economies increase with the degree of linkages across sectors, which is especially prominent in the case of the financial intermediation sector. Our paper contributes to the emerging macroeconomic literature on the propagation of shocks across sectors and the implications for the whole economy.
