Unemployment insurance systems are designed to provide income security for those who drop out of work temporarily. This form of social protection is particularly relevant for foreign-born workers who are, on average, more likely to become unemployed during layoffs. The article explores how the social protection of immigrants differs in cases where payments are tied to voluntary rather than mandatory contributions. This is done by focusing on a recent welfare reform in Sweden which led to both a sharp increase in costs and a decline in benefit generosity overnight. It is argued that migrants lost their social protection at a disproportionate rate over the course of the reform. Both their status on the labour market and position as newcomers to the norms and rules of society are expected to impede on their decision to obtain or prolong insurance membership, leading to a decline in eligibility to income security. Difference-in-difference estimates with administrative data from all unemployment insurance funds show that the share of benefit recipients with earnings-related payments decreased at a higher rate among the foreign-born as expected, especially if they had arrived in the country only recently.

失业保险制度旨在为暂时失业的人们提供收入保障。这种社会保护形式与平均而言，更容易在裁员中失业的外国出生工人有关。本文探讨了在付款与自愿捐款而非强制性捐款挂钩的情况下，移民的社会保护有何不同。这是通过关注瑞典最近的福利改革而实现的，该改革导致成本急剧增加，并且在一夜之间福利慷慨度下降。有人认为，移民在改革过程中丧失了不成比例的社会保护。他们在劳动力市场上的地位以及作为社会准则和社会规则的新成员的地位，都将阻碍他们决定获得或延长保险资格，从而导致收入保障资格的下降。来自所有失业保险基金的行政数据的差异估计表明，与收入相关的支付的受益人的比例在外国出生者中的下降幅度比预期的要高，尤其是如果他们是最近才来到该国的。
