Inequality Up, Mobility the Same

Tyler Cowen points us to the latest research on the American Dream:

This paper uses Social Security Administration longitudinal earnings micro data since 1937 to analyze the evolution of inequality and mobility in the United States. Earnings inequality follows a U-shape pattern, decreasing sharply up to 1953 and increasing steadily afterwards. We find that short-term and long-term (rank based) mobility among all workers has been quite stable since 1950 (after a temporary surge during World War II).
