The development push of refugees: evidence from Tanzania
利用1991-2010年坦桑尼亚家庭面板数据，研究发现来自布隆迪和卢旺达的临时难民流入对当地居民福利产生了持续正面影响，主要渠道是运输成本下降。
We exploit a 1991–2010 Tanzanian household panel to assess the effects of the temporary refugee inflows originating from Burundi (1993) and Rwanda (1994). We find that the refugee presence has had a persistent and positive impact on the welfare of the local population. We investigate the possible channels of transmission, underscoring the importance of a decrease in transport costs as a key driver of this persistent change in welfare. We interpret these findings as the ability of a temporary shock to induce a persistent shift in the equilibrium through subsequent investments rather than a switch to a new equilibrium in a multiple-equilibrium setting.
