    Abstract: We develop an assignment model of automation. Each of a continuum of tasks of variable complexity is assigned to either capital or one of a continuum of labor skills. We characterize conditions for interior automation, whereby tasks of intermediate complexity are assigned to capital. Interior automation arises when the most skilled workers have a comparative advantage in the most complex tasks relative to capital, and because the wages of the least skilled workers are sufficiently low relative to their productivity and the effective cost of capital in low-complexity tasks. Minimum wages and other sources of higher wages at the bottom make interior automation less likely. Starting with interior automation, a reduction in the cost of capital (or an increase in capital productivity) causes employment and wage polarization. Specifically, further automation pushes workers into tasks at the lower and upper ends of the task distribution. It also monotonically increases the skill premium above a skill threshold and reduces the skill premium below this threshold. Moreover, automation tends to reduce the real wage of workers with comparative advantage profiles close to that of capital. We show that large enough increases in capital productivity ultimately induce a transition to low-skill automation and qualitatively alter the effects of automation - thereafter inducing monotone increases in skill premia rather than wage polarization.

    Abstract: We employ a sample of nearly 40, 000 gender-targeted online job vacancies in Vietnam from February 2019 to July 2020 to investigate gender differences in returns to physical attractiveness. In particular, we compare the monthly offered wage in matched vacancies with and without beauty preferences of the same characteristics among job ads directed at men and women separately. We find evidence that better-looking women enjoy a wage premium of 3.7 percentage points, whereas better-looking men do not. Further analysis shows that the gender differences in returns to beauty are mainly driven by gender role attitudes and the perceived lack of fit rather than productivity-enhancing effect or employers' negligence in job postings.

    Abstract: Using a large survey of euro area consumers, we design an experiment in which respondents report how they would change the decision to participate in the labor market, the hours worked, and their search effort (if not employed) in response to randomly assigned windfall gain scenarios. Windfall gains reduce labor supply, but only if they are significant in size. At the extensive margin, we find no effect for gains below €25, 000, and a decline in the probability of working of 3 percentage points for gains between €25, 000 and €100, 000. At the intensive margin, there is no effect for small gains, and a drop of roughly one weekly hour for gains above €50, 000. Women and workers closer to retirement respond more strongly to windfall gains. Finally, the proportion of those who stop searching for a job or search less intensively falls by 1 percentage point for each €10, 000 gain, and the effect is more pronounced for older individuals receiving the largest prize.

    Abstract: We present evidence consistent with large disparities across firms in the on-the-job learning their young employees experience, using administrative datasets from Brazil and Italy. We categorize firms into discrete “classes†—which our conceptual framework interprets as skill-learning classes—using a clustering methodology that groups together firms with similar distributions of unexplained wage growth. Mincerian returns to experience vary widely across experiences acquired in different firm classes. Moreover, past experiences at firms with better on-the-job learning lead to subsequent jobs featuring greater non-routine task content. Three empirical tests leveraging firm stayers and movers, hiring wages, and displaced workers point towards a portable and general human capital interpretation. Heterogeneous employment experiences explain an important share of wage variance by age 35, thus contributing to shape wage inequality. Lastly, we show that firms’ observable attributes only mildly predict on-the-job learning opportunities.
