This paper is the first to examine the causal relationship between China's One-Child Policy (OCP) and the long-term accumulation of human capital by a regression discontinuity design. Based on the 2005 China Inter-census Survey data, we observe a strong policy shock upon the probability of being a single child among people born around the starting...

Policymakers are interested in the impact of health insurance on individuals’ medical expenditures—not only the average effect for the overall population, but also the possible heterogeneous effects for subgroups. This paper focuses on the heterogeneous impacts of a nationwide health insurance program in China, the New Rural Cooperative Medical Sch...

Objective This longitudinal study aimed to measure precarious employment in the US using a multidimensional indicator. Methods We used data from the National Longitudinal Survey of Youth (1988-2016) and the Occupational Information Network database to create a longitudinal precarious employment score (PES) among 7568 employed individuals over 18 wa...

Climate variability driven by El Niño-Southern Oscillation (ENSO) is a significant public health concern in parallel with global population aging; however, its role in healthy aging is less studied. We examined the longitudinal impacts of ENSO exposure on excess mortality and related medical costs in the elderly from 23 provinces of China. A total...

Two-sided digital platforms play an increasingly important role in our economy. During the COVID-19 pandemic, our involvement with these platforms increases drastically, but little is known about how the behavior of consumers and the labor market performance of workers in a two-sided market are affected by an economy-wide shock.

It was investigated whether increases in precarious employment were associated with changes in BMI in the United States. Methods Data were from the National Longitudinal Surv...

We estimated a structural model of production and wage determination in which labour quality can be affected by a firm's training decision using data of China's manufacturing enterprises in an era of privatization (2004–2007). Training increased both productivity and wages, but the former increased more, which explained the voluntary provision of o...
