Rising Top, Falling Bottom: Industries and Rising Wage Inequality

Abstract
Most of the rise in overall earnings inequality from 1996 to 2018 is accounted for by rising
between-industry dispersion. The contribution of industries is right-skewed with the top ten percent
of 4-digit NAICS industries dominating. The top ten percent are clustered in high-paying
high-tech and low-paying retail sectors. In the top industries, high-wage workers are increasingly
sorted to high-wage industries with rising industry premia. In the bottom industries, low-wage
workers are increasingly sorted into low-wage industries, with rising employment and falling industry
wage premia.
