We revisit the capital-skill complementarity hypothesis and examine whether and under what conditions this mechanism can explain the developments in wage inequality and labor share in the 1963–2016 period. Krusell, Ohanian, Ríos-Rull and Violante (2000) show that a model with capital-skill complementarity mechanism matches the data well and can account for changes in wage inequality in the 1963–1992 period. We show that applying the model to the 1963–2016 period delivers a good fit for the skill premium; however, it does not match the declining pattern in labor share in the last two decades. We modify the model to allow for a flexible technology structure and show that the degree of capital-skill complementarity is declining over time. The augmented model with time-varying capital-skill complementarity suggests explanations for the declining labor share.
