"A Dynamic Model of Personality, Schooling, and Occupational Choice," Quantitative Economics, 11.1 (2020): 231-275. (with Petra Todd) ​Supplemental Material Online Appendix. 
Abstract
This paper develops a dynamic model of schooling and occupational choices that incorporates personality traits, as measured by the “big five” traits. The model is estimated using the HILDA dataset from Australia. Personality traits are found to play an important role in explaining education and occupation choices over the lifecycle. Results show that individuals with a comparative advantage in schooling and white-collar work have, on average, higher cognitive skills and higher personality trait scores. Allowing personality traits to evolve with age and with schooling proves to be important to capturing the heterogeneity in how people respond to educational policies. The estimated model is used to evaluate two education policies: compulsory senior secondary school and a 50% college tuition subsidy. Both policies increase educational attainment and also affect personality traits.
“Personality Traits, Intra-household Allocation and the Gender Wage Gap,” European Economic Review, 109 (2018): 191-220. (with Christopher Flinn and Petra Todd) Supplemental Material
Abstract
A model of how personality traits affect household time and resource allocation decisions and wages is developed and estimated. In the model, households choose between two behavioral modes: cooperative or noncooperative. Spouses receive wage offers and allocate time to supply labor market hours and to produce a public good. Personality traits, measured by the so-called “Big Five” traits, can affect household bargaining weights and wage offers. Model parameters are estimated by Simulated Method of Moments using the Household Income and Labor Dynamics in Australia (HILDA) data. Personality traits are found to be important determinants of household bargaining weights and of wage offers and to have substantial implications for understanding the sources of gender wage disparities.
“Welfare Reform and Children's Early Cognitive Development,” Contemporary Economic Policy, 32.4 (2014): 729-751. (with Hau Chyi and Orgul Demet Ozturk)
Abstract
​In this paper, we use a dynamic structural model to measure the effects of (1) single mothers’ work and welfare use decisions and (2) welfare reform initiatives on the early cognitive development of the children of the NLSY79 mothers. We use PIAT-Math scores as a measure of attainment and show that both the mothers’ work and welfare use benefit children on average. Our simulation of a policy that combines a time limit with work requirement reduces the use of welfare and increases employment significantly. These changes in turn significantly increase children’s cognitive attainment. This implies that the welfare reform was not only successful in achieving its stated goals, but was also beneficial to welfare children’s outcomes. In another policy simulation, we show that increasing work incentives for welfare population by exempting labor income from welfare tax can be a very successful policy with some additional benefits for children’s outcomes. Finally, a counterfactual with an extended maternal leave policy significantly reduces employment and has negative, though economically insignificant, impact on cognitive outcomes.

“Distributional Effects of Local Minimum Wage Hikes: A Spatial Job Search Approach,” This version December 2018.  
SSRN Working Paper 3309362​.
Abstract
This paper develops and estimates a spatial general equilibrium job search model to study the effects of local and universal (federal) minimum wage policies. In the model, firms post vacancies in multiple locations. Workers, who are heterogeneous in terms of location and education types, engage in random search and can migrate or commute in response to job offers. I estimate the model by combining multiple databases including the American Community Survey (ACS) and Quarterly Workforce Indicators (QWI). The estimated model is used to analyze how minimum wage policies affect employment, wages, job postings, vacancies, migration/commuting, and welfare. Empirical results show that minimum wage increases in local county lead to an exit of low type (education < 12 years) workers and an influx of high type workers (education ≥ 12 years), which generates negative externalities for workers in neighboring areas. I use the model to simulate the effects of a range of minimum wages. Minimum wage increases up to $14/hour increase the welfare of high type workers but lower welfare of low type workers, expanding inequality. Increases in excess of $14/hour decrease welfare for all workers. I further evaluate two counterfactual policies: restricting labor mobility and preempting local minimum wage laws. For a range of minimum wages, both policies have negative impacts on the welfare of high type workers, but beneficial effects for low type workers.
"Labor Market Returns to Personality: A Job Search Approach to Understanding Gender Gaps​," This version January 2021. (with Christopher Flinn and Petra Todd)  An ealier version: Human Capital and Economic Opportunity Working Group Working Papers 2020-010. 
Abstract
This paper investigates the effects of the so-called big five personality traits on labor market outcomes and on gender disparities within a job search, matching and bargaining model with heterogeneous workers. In the model, parameters pertaining to productivity, job offer arrival rates, job dissolution rates and the division of surplus from an employer-employee match depend on worker personality traits, education, and other demographics. The model's estimation is based on a German panel dataset. Parameter estimates show that four of the five personality traits are statistically significant determinants of job search parameters and labor market outcomes. Also, women and men are rewarded differently for two traits, conscientiousness and agreeableness, which largely explains gender labor market disparities. If women were to receive the same return that men receive for their personality traits, the wage gap would be eliminated.
