摘要：
Although equal pay has received increasing attention over decades, pay equity among leadership and management positions often receives less attention. This study hypothesizes that women who are promoted to senior positions continue to experience a gender pay gap after the implementation of the Patient Protection and Affordable Care Act in 2010.
We examine a sample of hospital executives using data from the 2017 Internal Revenue Service 990 forms merged with the 2017 wave of the American Hospital Association survey. Available variables include hospital chief executive officers’ (CEOs) compensation and hospital characteristics. CEOs’ gender was identified by matching their first name with a database from the Social Security Administration. We conducted both ordinary least squares (OLS) and unconditional quantile regression (UQR) analysis. We used an Oaxaca decomposition analysis to explain the gender pay gap.
On average, the compensation for women CEO was 29.1% less than men based on a median regression while the OLS regression indicated a gender pay gap of 32.6% (p<0.01). Our UQR result revealed a U-shaped relationship across the salary distribution. We conclude that the gender pay gap between hospital CEOs persists and has widened. We need to continue to monitor and strive for pay equity in the healthcare industry.

摘要：
I investigate the optimal design of contests when contestants have both private information and convex effort costs. The designer has a fixed prize budget and her objective is to maximize the expected total effort. I first demonstrate that it is always optimal for the designer to employ a grand static contest with as many participants as possible. Further, I identify a sufficient and necessary condition for the winner-takes-all prize structure to be optimal. When this condition fails, the designer may prefer to award multiple prizes of descending sizes. I also provide a characterization of the optimal prize allocation rule for this case. Lastly, I illustrate how the optimal prize distribution evolves as contest size grows: the prize distribution first becomes more unequal until the optimal level of competition intensity is obtained and then becomes less unequal to maintain the optimal intensity.

摘要：
How to allocate college seats across regions is an important but often controversial question. It may imply a policy tradeoff between efficiency in human capital production and equality of opportunities for people growing up in different places. Regional disparity in college access also impacts the spatial distribution of college-educated workers and thus affects regional inequality in development. This paper studies the province-based college admission quotas in China and evaluates potential reforms. Despite longstanding concerns about the unequal quota allocation across provinces, little is known because China's college entrance exam is not comparable across provinces. Combining individual-level administrative data and college student surveys, I estimate a structural model of college and migration choice under quota constraints, together with a measurement model that can recover the nationally comparable distribution of pre-college human capital in each province. I find substantial gaps of pre-college human capital among college applicants across provinces, but these gaps are not well reflected by the admission quotas. A purely merit-based nationwide admission without provincial quotas increases efficiency at the cost of larger regional inequality: it increases college-student sorting and total human capital output during college, but decreases the college opportunity in less developed provinces and the share of college graduates working in those provinces.

摘要：
在碳达峰碳中和双重目标背景下，需要统筹好“发展”与“减排”的要求，加强能源、环境、经济的协同治理并实现多方共赢。然而，探索未来发展路径具有高度的不确定性，协同实现环境与发展的多重目标也错综复杂。在面向未来的科学决策过程中，基于情景模拟和定量分析的系统分析模型可作为有力的支撑工具。由北京大学环境科学与工程学院能源环境经济与政策研究室(LEEEP)自主开发的IMED模型是一套适用于中国、区域和全球绿色低碳转型研究的模型体系。本报告旨在介绍运用IMED模型在不同的时间和空间尺度上评估环境和碳减排政策在环境和人群健康改善方面所带来的综合影响，并评估其成本效益，从而为双碳政策制定提供科学支撑。
