The labour market consequences of hosting refugees
利用坦桑尼亚西北部1990年代难民涌入前后的面板数据，发现难民流入使当地人更可能从事家庭农业或养殖，而更少外出打工，尤其是对之前做零工的人影响最大。
During the 1990s, the northwestern region of Tanzania experienced a large inflow of refugees. Using panel data (pre- and post-refugee inflow), we estimate the labour market consequences of hosting those refugees. Results are consistent with immigration affecting the allocation of natives across economic activities. Greater exposure to the refugee shock resulted in Tanzanians having a higher likelihood of working in household shambas or caring for household livestock and a lower likelihood of working outside the household as employees. The latter effect was particularly strong for Tanzanians doing casual work before the shock. This coincides with anecdotal evidence of refugees concentrating in casual waged work in Tanzania and competing directly with Tanzanians for those jobs.
