Poverty alleviation in Mozambique: a multi‐market analysis of the role of food aid
研究了莫桑比克马普托家庭的需求系统，发现进口黄玉米能自动瞄准贫困家庭，且对本地农业的抑制效应很小。
Abstract The use of food aid in poverty alleviation programs has been hampered by two problems: the inability to target to households in need, and the disincentive effects on agriculture. In this paper, we present econometric estimates of in Almost Ideal Demand System (AIDS) for households in Maputo, Mozambique, and develop a multi‐market model to show that in Maputo, imported yellow maize is not only self‐targeting, but that owing to a combination of the low cross‐price elasticity with locally produced staples (particularly, white maize) and cross‐border trade in food products, the disincentive effects on domestic agriculture have been negligible.
