The dataset accompanying “Capital-Skill Complementarity and Inequality: Twenty Years After” (Economics Letters, 2022) extends the original Krusell–Ohanian–Ríos-Rull–Violante (2000) dataset by incorporating updated observations for the period 1993–2017, resulting in a unified time series covering 1963–2017.

The dataset combines micro-level labor market information from the Current Population Survey (CPS March Supplements) with macroeconomic aggregates from the Bureau of Economic Analysis (BEA) and the Federal Reserve Bank of St. Louis. It includes: - Skilled and unskilled labor input (hours and population levels) - Weekly wages by skill group - Skill premium (wage ratio skilled/unskilled) - Capital equipment and capital structures (real stocks) - Relative and quality-adjusted price of equipment - Aggregate output and labor share of income
