This paper proposes a new approach to modeling heterogeneous human capital using task data from the Dictionary of Occupational Titles. The key feature of the model is that it departs from the Roy model, which treats occupations as distinct categories, and conceives of occupations as bundles of...

This paper studies implicit pricing of non-wage job characteristics in the labour market using a two-sided matching model. It departs from the previous literature by allowing worker heterogeneity in productivity, which gives rise to a double transaction problem in a hedonic model. Deriving...

What are the sources of rapid wage growth during a worker’s early career? To address this question, I construct and estimate a model of strategic wage bargaining with on-the-job search to explore three different components of wages: general human capital, match-specific capital, and outside...

This paper examines how primitive skills associated with occupations are formed and rewarded in the labor market over the careers of men. The objective task complexity measurement from the Dictionary of Occupational Titles enables a more direct look into the primitive skills of workers. I show...

This paper constructs and estimates a career decision model where individuals search for both career matching and employer matching to understand wage growth and career mobility using the NLSY79. It departs from previous papers in that career mobility decisions and participation decisions are...

The goal of the paper is two-folds. First, I construct and estimate a dynamic structural occupational choice model at the three-digit classification level, in which different occupations involve different mix of tasks. Second, I conduct a counterfactual simulation using the estimated model, to...

How did skilled-biased technological change affect wage inequality, particularly between men and women? To answer that question this paper constructs a task-based Roy model in which workers possess a bundle of basic skills, and occupations are characterized as a bundle of basic tasks. The model...

We present what we believe are the best estimates of how job characteristics of physical demands and environmental conditions affect individual’s health. Five-year cumulative measures of these job characteristics are used to reflect findings in the physiologic literature that cumulative...

We estimate the causal effects of childcare availability on the maternal employment rate using prefecture panel data constructed from the Japanese quinquennial census 1990-2010. We depart from previous papers on Japan by controlling for prefecture fixed effects, without which the estimates can...
