Replication Data for \"Economic Determinants of Attitudes toward Migration: Firm-level Evidence from Europe\"

What are the distributional consequences of migration, and how do they affect attitudes toward migration? This paper leverages a natural experiment generated by the ousting of former Libyan dictator Muammar Gaddafi, which created an unprecedented influx of economic migrants from African countries to Europe. This surge of low-skilled labor benefited low-productivity firms by lowering their production costs and expanding their labor supply. Employing a triple difference-in-differences design, we document that attitudes toward migration improved in Western European regions with large shares of migrants and low-productivity firms. Evidence from Sweden, which provides finely grained geographical data, confirms these findings. We then test the economic microfoundations of this attitudinal shift. We show that the surge in the supply of low-skilled labor increased the profitability of low-productivity firms more in areas that experienced large migration flows than in those that received limited migration flows. We find no evidence that migration worsened natives' labor market conditions.移民会带来怎样的分配效应，又会如何影响公众对移民的态度？本文依托利比亚前独裁者穆阿迈尔·卡扎菲（Muammar Gaddafi）倒台所催生的自然实验——该事件引发了非洲国家向欧洲的史无前例的经济移民潮。此次低技能劳动力潮通过降低生产成本、扩大劳动力供给，惠及了低生产率企业。本文采用三重差分（triple difference-in-differences）模型进行实证分析，结果显示：在移民占比高且低生产率企业占比高的西欧地区，公众对移民的态度有所改善。得益于瑞典提供的精细化地理数据，来自该国的实证结果进一步验证了上述结论。随后，本文对这一态度转变的经济微观基础进行了检验。研究表明，相较于移民流入规模有限的地区，在移民流入规模较大的区域，低技能劳动力供给的增加对低生产率企业盈利能力的提升作用更为显著。本文未发现移民会恶化本土居民劳动力市场境况的相关证据。
