Book excerpt: The role of technological change in labor market polarization has been subject to recent critique. This paper finds that changes in production technology played an important role in wage and job polarization in the US. It also demonstrates that such technological change is consistentwith the timing of labor market polarization in the US, including the stagnation of the 50/10 wage percentile ratio and the slowdown of employment growth in high-wage jobs from the 2000s. The paper does so using a model with two key ingredients: 1) directed search and 2) two-sided multi-dimensional heterogeneity. Estimation results show that the complementarity between cognitive skill and task increased while that between manual skill and task did not. The full model can fullyaccount for the rise and fall of the 90/50 and 50/10 wage percentile ratios respectively. It also generates 72.6 percent of the rise in employment share of high-paying jobs relative to middling jobs and 69 percent of the fall in employment share of middling jobs relative to low-paying jobs. The paper suggests that the stagnation of the 50/10 wage ratio may be due to rank-switching between workers across the wage distribution from the 2000s, while the slowdown of employment growthin high-wage jobs may result from the trade-off between the returns to applying for high-wage jobs and the likelihood of being hired.
