abstract
This paper provides new estimates of wage inequality in the United States from 1918 to 1949, leveraging a novel top-income methodology that integrates both tax records and census data. Our analysis reveals no sustained decline in wage inequality before the Second World War but a marked decrease during the war years. This decline was driven primarily by stagnation among the top 1 % of earners and significant wage growth at the lower end of the income distribution. However, the relative underperformance of the top earners was largely influenced by a major compositional shift triggered by unprecedented increases in corporate and personal income tax rates. These tax changes led to a shift in business preferences toward partnerships, resulting in a substantial transition from salaried employment to self-employment. This shift, previously overlooked in inequality studies, resulted in a 30 % overestimation of wage compression, significantly altering the wage distribution dynamics of the 1940s.
