Short-term healthcare subsidies are commonly administered in low-income countries to promote long-term uptake of healthcare. To evaluate the impact of follow-up healthcare subsidies, we examined the effects of a one-time subsidy of providing free eyeglasses to school children in rural China. We contribute to the field by using a unique and rare 27-month, two-phase experiment that surveyed 4658 primary and secondary school students from Gansu and Shaanxi provinces in rural northwestern China. The sample was divided into an intervention group that received free eyeglasses for uncorrected refractive errors and a control group that received only prescription information. The impact of one-time subsidized eyeglasses on rural students’ long-term uptake of vision health care vision health was assessed using an instrumental variables (IV) approach. 90.0% of students from the intervention group that received one-time subsidized eyeglasses sought appropriate long-term healthcare, which was significantly higher (P &lt; 0.001) than the control group at 61.3%. Multivariate logistic regression models (OR = 28.315, 95% CI = 10.972–73.074, P &lt; 0.001) revealed that this one-time subsidy of free eyeglasses significantly predicted long-term uptake in related healthcare products and services. IV analysis suggested that wearing eyeglasses may increase the likelihood of students’ long-term uptake by 78.7% in the intervention samples compared to control schools; the magnitude of this coefficient provides evidence that wearing eyeglasses leads to a marginal improvement in long-term uptake within the sample. This result passed a series of robustness tests. Learning by doing and social learning are crucial pathways through which short-term, targeted subsidies might affect long-term adoption, at least for some classes of preventative health items. The provision of short-term, one-off healthcare subsidies can be an efficient and cost-effective strategy for boosting both short-term and long-term healthcare-seeking behavior.

To address this issue, we creatively construct a dataset of Chinese listed firms from 2000 to 2014 and conduct empirical tests using propensity score matching to investigate the impact of firms' intermediate goods import behavior on innovation performance at the micro level. We construct models of firms' decisions under closed market conditions and of the impact of intermediate goods imports on firms' innovation activities under open market conditions. Our study shows that firms that import intermediate goods are more innovative, and we validate the robustness of this result. We further discuss the potential mechanisms of how exposure to international markets affects innovation, and we find that firms' import behavior affects innovation through scale effect, technology effect, and profit effect. In short, importing intermediate goods enhances firm-level innovation in developing countries. Our study provides significant evidence on the impact of imports on firm-level innovation performance, and our findings provide a rationale for promoting the co-development of trade and firm innovation.

Understanding economic mobility is important because it shapes our perception of inequality. Despite its significance, evidence on intragenerational mobility, especially that based on administrative data, is relatively limited in developing countries. Using Thailand’s tax return data, we study the evolution of earnings inequality, estimate medium-term earnings mobility, and examine the heterogeneity of mobility across age, gender and employment arrangement. Our analysis yields three main findings. First, annual earnings inequality rises during the 2009–2018 period. We find that the inequality is largely permanent, and its increase is primarily driven by top-earnings workers. Second, medium-term mobility tends to be limited at both ends of the earnings distribution, with particularly pronounced persistence observed at the top decile. Our suggestive comparison indicates that Thailand’s earnings mobility is among the lowest in the pool of evidence from both developed and developing countries. Third, there is a considerable heterogeneity in mobility regarding employment arrangement. Workers in less-formal jobs have much lower upward mobility than those in more-formal employment.
