Who opposes refugees? Swedish demographics and attitudes towards forcibly displaced populations
利用1985-1994年间瑞典难民的准随机安置，研究哪些选民特征与反对移民的态度相关，并考察经济条件的影响。发现年轻男性、低财富者和蓝领工人更反对移民，而就业增长和低税收地区更支持。
Abstract We exploit the quasi-random settlement of refugees in Sweden between 1985 and 1994 to examine characteristics of Swedish voters who showed a disproportionately negative response to increased migration inflows, and we assess whether these responses differed according to economic conditions when refugees arrived. We document that, on average, increases in migration inflows translated to lower support for immigration. These responses disproportionately stemmed from attitudinal changes in young males, those with less wealth, and people who worked in blue-collar occupations. Also, we find more support for immigration where employment increased and tax collection was lower when refugees arrived.
