Using a new quarterly panel database on remittances (71 countries over the period 2011Q1- 2020Q4), this paper investigates the elasticity of remittances to transaction costs in a high frequency and dynamic setting. It adds to the literature by systematically exploring the heterogeneity in the cost-elasticity of remittances along several country characteristics. The findings suggest that cost reductions have a short-term positive impact on remittances, that dissipates beyond one quarter. According to our estimates, reducing transaction costs to the Sustainable Development Goal target of 3 percent could generate an additional US$32bn in remittances, higher that the direct cost savings from lower transaction costs, thus suggesting an absolute elasticity greater than one. Among remittance cost-mitigation factors, higher competition in the remittance market, a deeper financial sector, and adequate correspondent banking relationships are associated with a lower elasticity of remittance to transaction costs. Similarly, remittance cost-adaptation factors such as enhanced transparency in remittance costs, improved financial literary and higher ICT development coincide with remittances being less sensitive to transaction costs. Supplementing the panel analysis, the use of micro data from the USA-Mexico corridor confirm that migrants facing higher transaction costs tend to remit less, and that this effect is less pronounced for skilled migrants and those that have access to a bank account.

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.

Given the large size of aggregate remittance flows (billions of dollars annually), they should be expected to have significant macroeconomic effects on the economies that receive them. This paper directly addresses the two main issues of interest to policymakers with regard to remittances--how to manage their macroeconomic effects, and how to harness their development potential--by reporting the results of the first global study of the comprehensive macroeconomic effects of remittances on recipient economies. In broad terms, the findings of this paper tend to confirm the main benefit cited in the microeconomic literature: remittances improve households' welfare by lifting families out of poverty and insuring them against income shocks. The findings also yield a number of important caveats and policy considerations, however, that have largely been overlooked. The main challenge for policymakers in countries that receive significant flows of remittances is to design policies that promote remittances and increase their benefits while mitigating adverse side effects. Getting these policy prescriptions correct early on is imperative. Globalization and the aging of developed economy populations will ensure that demand for migrant workers remains robust for years to come. Hence, the volume of remittances likely will continue to grow, and with it, the challenge of unlocking the maximum societal benefit from these transfers.

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.

Transaction cost economics has and continues to be a fruitful area of research. There is still much to be done in the field with past research being used in conjunction with the vast number of contractual phenomena that have yet to be investigated in transaction cost economics terms. New challenges are posed by the need to move beyond the design of new contractual instruments (such as financial derivatives) to include an examination of the lurking hazards that attend contract implementation.

Remittances sent by African migrants have become an important source of external finance for countries in the Sub-Saharan African region. In many African countries, these flows are larger than foreign direct investment and portfolio debt and equity flows. In some cases, they are similar in size to official aid from multilateral and bilateral donors. Remittance markets in Africa, however, remain less developed than other regions. The share of informal or unrecorded remittances is among the highest for Sub-Saharan African countries. Remittance costs tend to be significantly higher in Africa both for sending remittances from outside the region and for within-Africa (South-South) remittance corridors. At the same time, the remittance landscape in Africa is rapidly changing with the introduction of new remittance technologies, in particular mobile money transfers and branchless banking. This book presents findings of surveys of remittance service providers conducted in eight Sub-Saharan African countries and in three key destination countries. It looks at issues relating to costs, competition, innovation and regulation, and discusses policy options for leveraging remittances for development in Africa.
