Occupational Complexity, Capital-Skill Complementarity, and the Evolution of U.S. Wage Inequality: A Quantitative Analysis
We document a strong, positive relationship between occupational problem complexity, measured from US data on problem-solving requirements, and occupational wage growth since 1980. In contrast, employment shifts toward more complex occupations have been modest, suggesting a race between the demand for and supply of complex skills. We rationalize these findings by formulating and structurally estimating a quantitative general equilibrium model on the granular occupational level. In our model, workers have heterogeneous comparative advantages in solving complex problems and physical capital ...

Uninsured risk, stagnation, and fiscal policy
Japan is in the midst of a protracted spell of depressed economic activity. Japan's economic stagnation has occurred against a background of rising earnings risk. Occupational stability is falling as routine occupations disappear and implicit lifetime employment guarantees are gradually disappearing. At the same time, earnings in some high-skilled occupations have continued to grow. The resulting polarization in earnings has also been accompanied by an increase in wealth inequality. We develop a framework that relates these observations. In our model, an increase in uninsured earnings risk ...
