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...

One of the pervasive issues in social and environmental research has been to improve the quality of socioeconomic data in developing countries. Because of the shortcoming of standard data sources, the present study examines luminosity (measures of nighttime lights) as a proxy for standard...

Using simulated patients to mimic nine established non-communicable and infectious diseases over 27 trials, we assess ChatGPT's effectiveness and reliability in diagnosing and treating common diseases in low- and middle-income countries. We find ChatGPT's performance varied within a single...

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 derives the structure of a production function which is necessary and sufficient for generating a fixed cost. We extend the classical production function in order to allow each input to have a fixed and a variable part. We characterize and estimates both fixed and variable components...

In this paper, we propose a population-based optimization algorithm, Sequential Monte Carlo Simulated Annealing (SMC-SA), for continuous global optimization. SMC-SA incorporates the sequential Monte Carlo method to track the converging sequence of Boltzmann distributions in simulated annealing....
