Abstract: This paper investigates how the privatization of the state sector in urban China during the late 1990s contributed to gender disparities in labor market outcomes, household decision-making, human capital investment, and family formation. Using a difference-in-differences design, we find that women, particularly in more mature cohorts, experienced significantly more adverse labor market outcomes than men. In turn, privatization has decreased married women's decision-making power within the household. Meanwhile, women in the school-to-work transition cohort increased their investment in human capital more than men, and both genders delayed marriage. The reform accounts for about 30\% of the widening gender earnings gap and the narrowing gender gap in education.

Abstract: This paper examines the long-term impact of privatization on the next generation’s educational and labor market outcomes, as well as its implications for intergenerational mobility. We leverage the 1997–2000 privatization of State-Owned Enterprises (SOEs) in urban China—which resulted in over 35 million layoffs—as a natural experiment. Using individual survey data and prefecture-level employment data from statistical yearbooks, we implement a triple-difference design that exploits variation in reform intensity across regions, children's birth cohorts, and whether their parents were employed in SOEs before the reform. Our findings reveal that the reform had a negative impact on human capital accumulation for the next generation: individuals exposed to the reform attained significantly fewer years of schooling and earned lower incomes later in life. These effects were particularly pronounced for girls and children whose fathers were laid off. Additionally, we find suggestive evidence of a decline in intergenerational persistence in income and education among households affected by layoffs.

Previously circulated under the title "Maternity Ward Crowding, Birth Outcomes, and Future Fertility and Healthcare Decisions: Evidence from California."

Abstract: The recent global trend of maternity ward closures is reshaping childbirth care delivery and intensifying capacity pressures on the remaining facilities. We study how overcrowding during a woman’s first childbirth influences both clinical practices and subsequent healthcare choices, using comprehensive administrative records on all California births between 1989 and 2017. Leveraging quasi-random, within-hospital variation in daily number of patients, we find that overcrowding reduces the intensity of medical interventions—such as C-sections, epidurals, inductions, and augmentations—consistent with efforts to relieve physician workload. The reduction in epidural use is concentrated among disadvantaged mothers, suggesting disparities in care access during high-demand periods. Despite these adjustments, we find no detectable adverse effects on immediate maternal or infant health. Looking beyond the initial birth, we show that overcrowding does not alter future fertility but significantly increases the likelihood that mothers switch hospitals for subsequent deliveries. These effects are non-linear and most concentrated in the busiest quartile. We find no systematic patterns in hospital selection, indicating that switching is driven primarily by negative first-birth experiences. Together, our findings highlight a critical trade-off: short-term operational adjustments during peak-demand days can preserve safety, but risk undermining patient experience and long-term patient loyalty.

Abstract: China’s unprecedented expansion of higher education in 1999, increased annual college enrollment from 1 million to 9.6 million by 2020. We trace the global ripple effects of that expansion by examining its impact on US graduate education and local economies surrounding college towns. Combining administrative data from China’s college admissions system and US visa data, we leverage the centralized quota system governing Chinese college admissions for identification and present three key findings. First, the expansion of Chinese undergraduate education drove graduate student flows to the US: every additional 100 college graduates in China led to 3.6 Chinese graduate students in the US. Second, Chinese master's students generated positive spillovers, driving the birth of new master's programs, and increasing the number of other international and American master's students, particularly in STEM fields. And third, the influx of international students supported local economies around college towns, raising job creation rates outside the universities, as well. Our findings highlight how domestic education policy in one country can reshape the academic and economic landscape of another through student migration and its broader spillovers.

Abstract: This paper examines the long-term impact of privatization on the next generation’s education, labor market outcomes, and intergenerational mobility. We study the 1997–2000 privatization of state-owned enterprises (SOEs) in urban China, which displaced more than 35 million workers. Using a triple-differences design that exploits variation in reform intensity across regions, children’s birth cohorts, and parents’ pre-reform employment status, we find that the reform reduced human capital accumulation and worsened long-run labor-market outcomes for the second generation. These adverse effects operate primarily through intergenerational transmission via parental layoffs, while rising returns to education during the reform period acted as a countervailing force. Furthermore, we show that the reform weakened intergenerational income persistence, which we attribute to the erosion of network-based job search following the reform.

China's healthcare system provides a unique context for studying the dynamics of patient-physician relationships, as patients are not assigned a primary care provider and have significant flexibility in choosing a doctor for each visit. Using administrative medical claims data from a city in China, this paper investigates the stickiness of patient-physician relationships and examines how patients respond when their regular doctors are on temporary leave.
