The Effect of Refugee Inflows on Host Communities: Evidence from Tanzania
研究了1993-1994年布隆迪和卢旺达难民涌入对坦桑尼亚西部收容社区的影响，发现非援助食品价格大幅上涨，而食品援助能缓解但不足以抵消难民人口增加带来的价格效应，并对城乡家庭财富产生不同影响。
Despite the large and growing number of humanitarian emergencies, there is little economic research on the impact of refugees and internally displaced people on the communities that receive them. This analysis of the impact of the refugee inflows from Burundi and Rwanda in 1993 and 1994 on host populations in western Tanzania shows large increases in the prices of nonaid food items and more modest price effects for aid-related food items. Food aid is shown to mitigate these effects, though its impact is smaller than that of the increases in the refugee population. Examination of household assets suggests positive wealth effects of refugee camps on nearby rural households and negative wealth effects on households in urban areas.
