We leverage the U.S. Health and Retirement Survey 2000-2018 to examine trends in the prevalence of physical disability and social support among older adults with...

In light of the low public awareness of ozone pollution and the potential health threats posed by long-term ozone exposure, this study estimates the causal effect of long-term ozone exposure on respiratory mortality. By employing an instrumental variable based on the long-distance transmission...

Assortment optimization has received active explorations in the past few decades due to its practical importance. Despite the extensive literature dealing with optimization algorithms and latent score estimation, uncertainty quantification for the optimal assortment still needs to be explored...

This paper offers one of the first evidence in a developing country context that transitory exposure to high temperatures may disrupt low-stakes cognitive activities across a range of age cohorts. By matching eight years of repeated cognitive tests among all the participants in a nationally...

Cognitive misperception contributed to poor decision-making; yet their impact on health-related decisions is less known. We examined how self-perceived memory was associated with chronic disease awareness among older Chinese adults. Data were obtained from the China Health and Retirement...

We develop a model of coordination and allocation of decentralized multi-sided markets, in which our theoretical analysis is promisingly optimizing the decentralized transaction packaging process at high-throughput blockchains or Web 3.0 platforms. In contrast to the stylized centralized...

This study is one of the first investigating the causal evidence of the morbidity costs of fine particulates (PM2.5) for all age cohorts in a developing country, using individual-level health spending data from a basic medical insurance program in Wuhan, China. Our instrumental variable (IV)...

Retirement, a major transition in the life course, may affect many aspects of retirees’ well-being, including health and health care utilization. Leveraging differential statutory retirement age (SRA) by occupation for China’s urban female workers, we provide some of the first evidence on...

Decentralized Autonomous Organization (DAO) provides a decentralized governance solution through blockchain, where decision-making process relies on on-chain voting and follows majority rule. This paper focuses on the most influential DAO, namely MakerDAO, and we find voters fall into different...
