The increasing volume of remittances and public transfers in rural areas of the developing world has raised hopes that these cash inflows may serve as an effective mechanism for reducing poverty in the long term by facilitating investments and raising productivity, particularly in agriculture where market failures are most manifest. This book systematically tests the empirical relationship between cash transfers and productive spending in agriculture amongst rural households in six different countries of the developing world. Together, the studies point to little impact of migration and public and private transfers on agricultural productivity, instead facilitating a transition away from agriculture or to a less labour intensive type of agriculture.
