Immigration, Unemployment and Pensions
研究了移民对拥有福利国家制度的东道国的影响，发现低技能移民提高失业率，损害低技能本地人但有益于高技能本地人和养老金领取者，整体上移民仍为本地人口带来净收益，但养老金体系扩张可能削弱这一收益。
Abstract This paper examines the impact of immigration on a host country with welfare state arrangements that support both the unemployed and the elderly. It is shown that low‐skilled immigration increases the unemployment rate. Furthermore, it harms the low‐skilled native population and benefits the high‐skilled natives and pensioners. Nevertheless, as under competitive labor markets, immigration generates an unambiguous gain for the native population as a whole. However, in contrast to the findings under full employment, this gain can be dampened by an expansion of the pension system.
