We consider a model of network interactions where the outcome of a unit depends on the outcomes of the connected units. We determine the key network link, i.e., the network link whose removal results in the largest reduction in the aggregate outcomes, and provide a measure that quantifies the...

This paper examines the role of various socioeconomic factors in mediating the local and cross-city transmissions of the novel coronavirus 2019 (COVID-19) in China. We implement a machine learning approach to select instrumental variables that strongly predict virus transmission among the rich...

This paper models the local and cross-city transmissions of the novel coronavirus in China between January 19 and February 29 in 2020. We examine the role of various socioeconomic mediating factors, including public health measures that encourage social distancing in local communities. Weather...

We leverage the timing of coalmine accidents to examine the effect of coal mining on air pollution. Safety regulations mandate that coal mining be suspended if a mine experiences an accident with 10 or more fatalities. We use a stacked difference-in-differences approach to compare counties with...

Ground-level ozone is a continuing problem worldwide, but research on the influences of ozone pollution on labour productivity in developing countries is insufficient. We investigate the effect of ozone pollution on outdoor worker productivity in the service sector using a unique panel dataset...

This paper reviews the latest evidence of the effects of early life circumstances on old-age health, distinguishing in utero exposures from childhood exposures to a wide range of environments. We then leverage the growing number of studies of the impact of the Great Chinese Famine (1959-1961) on...

Dementia leads public health issue worldwide. China has the largest population of adults living with dementia in the world, imposing increasing burdens on the public health and healthcare systems. Despite improved access to health services, inadequate and uneven dementia management remains...

We examine the causal effect of air pollution on an individual's propensity for entrepreneurship in China. Our preferred model, which employs an instrumental variable approach to address endogeneity arising from sorting into entrepreneurship and locational choices, suggests that exposure to...

We examine the causal effect of air pollution on an individual's propensity for entrepreneurship in China. Our preferred model, which employs an instrumental variable approach to address endogeneity arising from sorting into entrepreneurship and locational choices, suggests that exposure to...

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)...
