Migration remittances and development : [international conference jointly organised by the OECD and the Central Popular Bank of Morocco with the support of the Agence Française de Développment on migration remittances and the economic development of sending countries held in February 2005 in Marrakech] This publication presents the current situation with regard to the magnitude and economic impact of migrants remittances to their countries of origin. In 2004 remittances exceeded official development aid in several emigration countries: they totalled USD 126 billion according to IMF estimates. The book surveys the channels used to collect these funds; the role of banking systems and other financial institutions; the introduction of new technologies and their impact on fund collection; how the funds are transferred; and how to reduce the costs. Focus is also placed on the different ways in which migrants themselves participate together with non governmental organizations host countries and sending countries to open up new avenues for policies on development aid and co development. The direct role that migrants can play at the local level is highlighted. Several countries and regions are illustrated: Southern European countries Mexico Turkey North African and sub Saharan African countries the Philippines and some Latin American countries.
