The Effect of Emigration from Poland on Polish Wages
利用1998-2007年波兰家庭数据，研究发现移民导致高技能和中技能工人工资小幅上升，低技能工人工资可能下降。
Abstract In this paper, we analyse the effect of emigration from Poland on Polish wages. Focusing on the 1998–2007 period for Poland, we use a unique dataset that contains information about household members who are currently living abroad, which allows us to develop region‐specific emigration rates and to estimate the effect of emigration on wages using within‐region variation. Our findings show that emigration led to a slight increase in wages for high‐ and medium‐skilled workers, which are the two groups with the largest relative outmigration rates. Workers at the low end of the skill distribution might have experienced wage decreases.
