Economic development and intergenerational earnings mobility: Evidence from Taiwan
(Te Herenga Waka—Victoria University of Wellington, 2016) Chu, Luke Yu-Wei; Lin, Ming-Jen
How economic development affects intergenerational earnings elasticity is not well-documented. In this paper, we estimate intergenerational earnings elasticities between fathers and sons in two periods. In the current period, 2005–2010, Taiwan is already a developed economy with slower economic growth. We apply the two-sample approach developed by Björklund and Jäntti (1997) and find that intergenerational earnings elasticity is around 0.4–0.5 in this period. In the earlier period, 1990–1994, Taiwan was still a developing economy with fast economic growth. We mimic the Björklund-Jäntti two-sample approach and use average earnings by occupation as a proxy for fathers’ earnings. To quantify potential bias, we apply the same method to the 2005–2010 data. Our proxy method yields similar estimates in both the early 1990s and late 2000s. These results suggest stable intergenerational transmission of economic status in Taiwan, despite its rapid economic development.

Gender gap in upward mobility: What is the role of non-cognitive traits?
(Te Herenga Waka—Victoria University of Wellington, 2015) Chu, Luke Yu-Wei; Linz, Susan J.
Do non-cognitive traits contribute to the gender gap in supervisory status and promotion? We use a large linked employer-employee dataset collected from six former socialist countries to assess the link between non-cognitive traits and upward mobility. Controlling for on workplace heterogeneity, we find that gender differences in locus of control, the preference for challenge versus affiliation, and adherence to work ethic together can explain about 7–18% of the gender gap in supervisory status and promotions Overall, non-cognitive traits provide an important, though incomplete, explanation for the gender gap in upward mobility.

High times: The effect of medical marijuana laws on student time use
(Te Herenga Waka—Victoria University of Wellington, 2016) Chu, Luke Yu-Wei; Gershenson, Seth
Medical marijuana laws (MMLs) represent a major change of marijuana policy in the U.S. Previous research shows that these laws increase marijuana use among adults. In this paper, we estimate the effects of MMLs on secondary and post-secondary students’ time use using data from the American Time Use Survey. We apply a difference-in-differences research design and estimate flexible fixed effects models that condition on state fixed effects and state-specific time trends. We find no effect of MMLs on secondary students’ time use. However, we find that college students in MML states spend approximately 20% less time on education-related activities and 20% more time on leisure activities than their counterparts in non-MML states. These behavioral responses largely occur during weekends and summer when students have more spare time. Finally, the impacts of MMLs are heterogeneous and stronger among part-time college students, who are more likely to be first-generation college goers and to come from underrepresented racial and ethnic groups.
