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 quantify the effects of progressive income tax on post-schooling human capital investment and occupational choices. In the model, various skills are acquired through learning-by-doing, depending on the tasks of the experienced occupations. The key feature of the model is that, unlike occupation specific human capital, the acquired skills can be partly transferred to other occupations. Hence, some of low skill occupations can be viewed as "stepping stone" to better occupations. The structural parameters of the model are estimated using the occupational characteristics in the Dictionary of Occupational Titles and the work history in the National Longitudinal Survey of Youth 79. The results of a counterfactual simulation in the estimated model indicate that switching to a flat income tax encourages mobility to highpaying occupations and accelerates human capital accumulation. A drawback of the tax code change is an increased inequality between educational groups.

This paper constructs and structurally estimates a dynamic occupational choice model that has two distinct features. First, an occupation is vertically and horizontally differentiated by a multidimensional task complexity measure. This allows a simultaneous analysis of career progression and comparative advantage. Second, the model includes hundreds of occupations by characterizing all jobs by a multidimensional task complexity vector, thereby avoiding the curse of dimensionality. Estimation results from the Dictionary of Occupational Titles (DOT) and the National Longitudinal Survey of Youth 1979 (NLSY) indicate that wages increase according to task complexity and that individuals climb up the career ladder along the dimension of tasks in which they have a comparative advantage.

This paper constructs and estimates a structural dynamic model of occupational choice in which all occupations are characterized in a skill requirement space using data from the Dictionary of Occupational Titles and the NLSY79. This skill requirement space approach has its merit in computational simplicity as well as ease of interpretation: it allows the model to include hundreds of occupations at the three-digit census classification level without a large number of parameters. Parameter estimates indicate that wages grow with the skill requirements of an occupation and that educated and experienced individuals are better rewarded in a cognitive and interpersonal skill demanding occupation. They also suggest that ignoring self-selection into occupations and individual heterogeneity may result in counter-intuitive and biased estimates of the returns to skill requirements.

This article constructs and estimates a model of wage bargaining with on-the-job search to explore three different components of wages: general human capital, match-specific capital, and outside options. As the workers find better job opportunities, the current employer has to compete with outside firms to retain them. This between-firm competition results in wage growth even when productivity remains the same. The model is estimated by a simulated minimum distance estimator and data from the 1979 National Longitudinal Study of Youth. The results indicate that the improved value of the outside option raises wages by 14%–16% in the first 5 years.

This article 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 tasks. The advantages of this approach are that it can accommodate many occupations without computational burden and provide a clear interpretation as to how and why skills are differently rewarded across occupations. The model is structurally estimated by the Kalman filter using the National Longitudinal Survey of Youth 1979.

The Effect of Match Quality and Specific Experience on Career Decisions and Wage Growth

Keyword(s): Career Patterns; College Graduates; High School Completion/Graduates; Mobility, Labor Market; Modeling; Wage Growth

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. Career mobility decisions and participation decisions are explicitly modeled. Findings suggest substantial returns to career-specific experience. However, college graduates' wages grow little through career-match upgrading, which results in a lower incidence of career changes than high school graduates. The finding suggests that college graduates learn about their suitable careers before they enter a labor market. The paper uses NLSY79 information on white males from the cross-sectional sample only.

This paper constructs and estimates a career decision model where individuals search for both careers and firms that are a good match for their idiosyncratic skills using the NLSY79. It departs from previous papers in that career mobility decisions and participation decisions are explicitly modeled. I find substantial returns to career-specific experience. However, college graduates' wage grows little through career-match upgrading, which results in a lower incidence of career changes than high school graduates. The finding suggests that college graduates learn about their suitable careers before they enter a labor market.

Three Essays in Labor Economics

The first essay evaluates the effect of match quality and career and firm specific experience on career decisions when a worker searches for both career and employer matching. I construct a dynamic career decision model which departs from the previous work in two respects. First, it deals with heterogeneous agents who have different educational background, experience, and unobserved skills. Second, the returns to tenure and career specific experiences are taken into account. I show that match qualities have significant effect on job and career turnover decisions, for male high school graduates in NLSY. The second essay asks what the sources of rapid wage growth during a worker's early career are. 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 option. The model is estimated by a simulated minimum distance estimator and data from the NLSY 79. The results indicate that the improved value of outside option raises wages of ten-year-experienced workers by 13%, which accounts for about a quarter of the wage growth during the first ten years of career. I also find that human capital accumulation affects wage profile not only because it directly changes labor productivity, but also because it alters job search behavior due to low future productivity. Final essay considers intertemporal decision making of collective agents. Evidence collected using the Panel Study of Income Dynamics (PSID) indicates that labor supply, saving, and marital decisions are strongly linked. The essay presents and simulates an intertemporal collective model with limited commitment using the PSID. The results indicate that the proposed model can match most of the features displayed by the data. The model is relevant to pending marriage tax relief legislation, as well as other changes in tax and transfer rules that simultaneously affect incentives for marriage, labor supply and wealth accumulation.
