We link administrative data on tax returns across two generations of Italians to study the degree of intergenerational mobility. We estimate that a child with parental income below the median is expected to belong to the 44th percentile of its own income distribution as an adult, and the...

After a decade in which wages and employment fell precipitously in low-skill occupations and expanded in high-skill occupations, the shape of U.S. earnings and job growth sharply polarized in the 1990s. Employment shares and relative earnings rose in both low and high-skill jobs, leading to a...

The share of low-income countries in global exports nearly tripled between 1990 and 2015, driven largely by the rapid emergence of China as an exporting powerhouse. While research in economics had long acknowledged that trade with lower-income countries could raise income inequality in Europe...

Concerns about widening inequality have increased attention on the topic of equality of opportunities and intergenerational mobility. We use data from the National Longitudinal Survey of Youth to analyse how educational and income mobility has evolved in the United States of America. We show...

We offer an integrated explanation and empirical analysis of the polarization of U.S. employment and wages between 1980 and 2005, and the concurrent growth of low skill service occupations. We attribute polarization to the interaction between consumer preferences, which favor variety over...
