Three Essays on Immigration and the Labor Market

The aim of this thesis is to examine heterogeneity in immigration impacts on both the native-born population and the immigrants. It consists of three essays that all use administrative register data from Norway and exploit a substantial variation over time and across countries of origin in immigration to Norway during the past decades. Chapter 1 analyzes the effects of Eastern European immigration on the earnings of natives employed in different occupations. Chapter 2 examines the effects of low- and high-income immigration, respectively, on natives’ economic mobility; that is, their prime-age earnings rank relative to the earnings rank of their parents. Finally, Chapter 3 investigates the economic mobility of immigrants from three country of origin groups and the underlying mechanisms behind migrants’ economic success, in particular whether entrepreneurship contributes to higher earnings growth among immigrants
