Immigration and the Canadian Earnings Distribution in the First Half of the Twentieth Century
利用1911至1941年加拿大人口普查微观数据，研究移民对收入分布的影响，发现移民并非两次世界大战期间收入不平等加剧的主因，这源于移民自我选择、职业调整及一般均衡效应。
We use newly available micro-data from the 1911 to 1941 Canadian Censuses to investigate the impact of immigration on the Canadian earnings distribution in the first half of the twentieth century. We show that Canadian inequality rose sharply in the inter-war years, particularly in the 1920s, coinciding with two of the largest immigration decades in Canadian history. We find that immigration was not the main force driving changes in the earnings distribution. This results from a combination of self-selection by immigrants, occupational adjustments after arrival, and general equilibrium adjustments in the economy.
