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...

During the first wave of the COVID-19 pandemic, Shanghai implemented lockdown measures to stop transmission of the virus. Over 26 million residents, including 0.8 million children aged 3-6, were confined at home. This study leveraged a city-wide cohort of preschool children - the Shanghai...

Given the critical role of neurocognitive development in early life, this study assesses how racial differences in early-life circumstances are collectively and individually associated with racial disparities in late-life cognition. Leveraging uniquely rich information on life history from the...

Growing evidence suggests that place of birth (PoB) and related circumstances may have long-lasting and multiplicative contributions to various later-life outcomes. This study investigates the extent to which PoB contributes to a wide range of domains of later-life cognitive function. Leveraging...

This paper examines the impact of the New Rural Pension Scheme (NRPS) in China. Exploiting the staggered implementation of an NRPS policy expansion that began in 2009, we used a difference-in-difference approach to study the effects of the introduction of pension benefits on the health status,...

Recent studies have proposed causal machine learning (CML) methods to estimate conditional average treatment effects (CATEs). In this study, I investigate whether CML methods add value compared to conventional CATE estimators by re-evaluating Connecticut's Jobs First welfare experiment. This...

This paper investigates the impact of attending early childcare on second generation immigrant children's cognitive outcomes. Our analysis draws on administrative data on the entire population of students in fifth grade collected by the Italian Institute for the Evaluation of the Educational...

But they could also improve workers' welfare by allowing them to take on more risk, for example through self-employment. This...

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...
