Global, Regional, and Country Level Prevalence of Young Children Exposed to Risks of Poor Development in Low and Middle Income Countries: An Update

 

Quantifying the prevalence of young children exposed to risks of poor development is imperative for understanding the challenges of reducing those risks, developing and evaluating evidence-based early childhood development policy interventions, and assessing progress in eliminating the risks imposed upon young children during their most critical developmental period. We published estimates on the prevalence of young children exposed to stunting and extreme poverty at the global, regional, and country levels in 2017. Since new data have been released and a new definition of extreme poverty has been proposed, we updated our 2017 study with a focus on the progress in reducing the prevalence of risk exposure at different levels since 2000. For countries with other risk factors available in their micro-level data, we added them to the composite measure and assessed the levels and trends of sociodemographic disparities in young children’s risk exposure.

This talk examines how age and generational differences shape smartphone adoption patterns in South Korea, one of the world's most rapidly aging societies. Using discrete-time hazard models, the analysis investigates whether digital divides reflect temporary life stage effects or persistent generational differences that accompany cohorts throughout their lives. Preliminary results reveal striking heterogeneity both across and within age cohorts, suggesting that neither age nor cohort membership alone fully explains adoption patterns. Motivated by these findings, the talk concludes by introducing an age-period-cohort framework designed to separate the distinct effects of aging, different formative experiences (cohort effect), and changing environment (period effect) on technology adoption.

Speaker:

Jinseok Kim headshot

Jinseok Kim is a Visiting Postdoctoral Fellow at Stanford’s Shorenstein Asia-Pacific Research Center (APARC) and the Stanford Next Asia Policy Lab (SNAPL). His research examines economic decision-making and technology adoption through the lens of behavioral and applied microeconomics. Using econometric modeling and experimental approaches, he studies consumer behavior, innovation diffusion, and the interaction between policy, markets, and demographic change. His work contributes to understanding how psychological factors and institutional contexts shape economic choices and the adoption of new technologies.

Yuli Xu Poster

Continuity of medical care is widely observed, but it is often difficult to disentangle patients’ intrinsic preferences from system-imposed switching costs. In this webinar, Dr. Yuli Xu discusses a study that uses the Chinese healthcare setting, where patients can freely choose physicians at each visit and flexibly switch across hospitals and departments, to isolate patients’ value of physician continuity.

Estimating a discrete choice model, the study shows that patients strongly prefer to see the same physician despite minimal institutional barriers to switching, indicating an intrinsic preference for continuity. The study also examines how physicians’ temporary leave affects patient behavior, using a stacked difference-in-differences design. A physician’s absence leads to significant reductions in patient visits, both within the physician’s department and across other departments in the same hospital, with no substitution toward other hospitals and no detectable effects on health outcomes. Patients return to their original physicians once they resume practice. Moreover, patients with more severe conditions incur higher spending when forced to see a new physician. Overall, the findings demonstrate that patients place substantial intrinsic value on physician continuity, even in a healthcare system with highly flexible provider choice.

Yuli Xu

Yuli Xu joins the Walter H. Shorenstein Asia-Pacific Research Center (APARC) as Asia Health Policy Postdoctoral Fellow for the 2025-2026 academic year. She recently obtained her Ph.D. in Economics at the University of California, San Diego. Her research focuses on Labor and Health Economics, with particular interests in how female labor force participation and fertility decisions are influenced by labor market institutions and past birth experiences. In her thesis, "Gendered Impacts of Privatization: A Life Cycle Perspective from China," she demonstrates that the reduction in public sector employment has widened the gender gap in the labor market while narrowing the gender gap in educational attainment. She also finds that this structural shift has delayed marriage among younger generations.

In another line of research, Yuli examines the effects of maternity ward overcrowding. She finds that overcrowding reduces the use of medical procedures during childbirth without negatively impacting maternal or infant health. While it has no direct effect on subsequent fertility, she shows that mothers, especially those with a college degree, are more likely to switch to another hospital for subsequent births after experiencing overcrowding. During her time at APARC, Yuli will further investigate patient-physician relationships in the Chinese healthcare system, where patients have considerable flexibility in choosing their doctors at each visit. She will explore the persistence of these relationships and examine how patients respond when their regular doctors are temporarily unavailable.

Yuli also holds a B.A. in Economics from the University of International Business and Economics in China.

Former Stanford President John Hennessy moderated a conversation about AI’s impact on the world with distinguished technology executive Craig Mundie and New York Times columnist Thomas Friedman. As AI continues its unprecedented transformation of our world, Mundie and Friedman reflected on their 25-year friendship and discussed the technological and societal trends that led them to argue, in a recent op-ed, that humanity has entered a new era of civilization. They explored the implications of this shift for daily life and geopolitics, as well as the technical and normative frameworks needed to establish trust in AI systems.
