摘要:
本文研究了居家社区养老服务供给对老年人精神健康的影响,使用中国健康与养老追踪调查(CHARLS)2011—2018年数据,使用双重差分方法解决内生性问题。结果表明,居家和社区养老试点显著改善了老年人精神健康状况。异质性结果表明,这一政策只对城镇地区、高收入、无慢性病以及自认为健康的老年人的精神健康状况产生了显著的改善作用,从而可能扩大老年人的健康不平等。政策实施后,老年人能够在家或附近社区就近享受到高质量的养老服务、能够在日常生活中得到更多照料和陪伴是这一政策改善老年人精神健康状况的两个重要机制。最后,这一试点政策对老年人健康满意度也有一定的改善作用,显著降低了老年人家庭的医疗支出负担,增加了老年人对子女的转移支付。

主讲人简介:
Zhiyu (Frank) Quan is an Assistant Professor at the Department of Mathematics of the University of Illinois at Urbana-Champaign. He holds a Ph.D. in Actuarial Science from the University of Connecticut. Before joining Illinois, he worked in a cutting-edge Insurtech company as a R & D data scientist developing data-driven solutions for major insurance companies. He has a broad spectrum of research interests in data science applications in insurance such as tree-based models, natural language processing, deep learning, and applies his actuarial expertise to build predictive models for claim research, rate making, etc. His research projects are driven by real-life data and are inspired from collaborations with Insurtech and insurance companies. Besides, he is a faculty advisor of the Illinois Risk Lab, which facilitates research activities that integrate academic training with practical problem-solving in real business settings. He has received the Arnold O. Beckman Research Award and has been awarded by the Society of Actuaries Research Institute.
摘要 :
Two-part framework and the Tweedie generalized linear model (GLM) have traditionally been used to model loss costs for short-term insurance contracts. For most portfolios of insurance claims, there is typically a large proportion of zero claims that leads to imbalances resulting in inferior prediction accuracy of these traditional approaches. In this article, we propose the use of tree-based methods with a hybrid structure that involves a two-step algorithm as an alternative approach. The first step is the construction of a classification tree to build the probability model for claim frequency. The second step is the application of elastic net regression models at each terminal node from the classification tree to build the distribution models for claim severity. This hybrid structure captures the benefits of tuning hyperparameters at each step of the algorithm; this allows for improved prediction accuracy and tuning can be performed to meet specific business objectives. A major clear advantage of this hybrid structure is improved model interpretability. We examine and compare the predictive performance of such a hybrid structure relative to the traditional Tweedie GLM using both simulated and real datasets. Our empirical results show that these hybrid tree-based methods produce more accurate and more informative predictions.

摘要:
损失补偿原则仅适用于财产保险之观点在保险法著述中广为传播,在保险法实践中亦有深远影响。然而,损失补偿是保险的本质与保险业产生发展之基础,也是保险业经济补偿功能之集中体现,损失补偿原则适用于包括人身保险之保险全领域实为其应有之义。人身保险非损失保险观点或是大陆法系国家损害赔偿理论及其限制非财产损害赔偿规定向保险法不当扩张之结果。在现代社会,人身保险的损失补偿性已为生命价值理论与第三领域保险的丰富实践所证实。保险损失补偿原则在中国的准确适用有赖于对其民商法理论基础之厘清、对人身保险损失计算标准之明晰,及对现行保险法下保险定义之完善。

摘要:
We study a generalization of the classical monopoly insurance problem under adverse selection (see Stiglitz 1977) where we allow for a random distribution of losses, possibly correlated with the agent's risk parameter that is private information. Our model explains patterns of observed customer behaviour and predicts insurance contracts most often observed in practice: these consist of menus of several deductible-premium pairs, or menus of insurance with coverage limits-premium pairs. The main departure from the classical insurance literature is obtained here by endowing the agents with risk-averse preferences that can be represented by a dual utility functional (Yaari 1987).

摘要:
发挥公募基金等机构投资者在维护市场稳定中的作用对于我国资本市场发展意义重大。然而,根据 2010~2022 年基金披露的前十大重仓股,基金重仓持股比例、基金减持比例均与股价崩盘风险之间显著正相关。为此,本文建立理论模型,提出基金共同持股下的集中抛售是导致股价崩盘的重要渠道。结合理论预测与实证结果,本文验证了该渠道的存在性,并发现持股基金的集中程度越低、长期持股倾向越强、业绩排名压力越轻,均有助于减轻基金持股对于股价崩盘风险的影响。本文的结论有助于深入理解机构投资者如何影响股价变化,特别是机构投资者之间的策略性博弈与竞争行为如何影响股价的暴涨暴跌风险。

摘要:
This paper exploits a regression discontinuity design to investigate how managers attribute responsibility when they miss a firm target in the relative performance contract. Using a measure based on causal words and sentences in the Management Discussion and Analysis (MD&A) section of 10-K filings as proxies of CEO's Self-Attribution Bias, we find that CEOs are more likely to attribute responsibility to the competitors or the industry when they miss a target. Our finding improves the understanding and the interpreting of firm reports, and our understanding of managerial behavior.

摘要:
This paper is to study the Pareto efficiency of the equilibrium allocation in OLG models with three production factors: physical capital, labor and natural resource. We present general sufficient conditions and general necessary conditions for the Pareto efficiency of the equilibrium allocation. Then, the general results are applied to two cases: the natural resource regeneration function is linear or quadratic, respectively. In the linear case (with additive log utility function and CES production function), we prove that there are a continuum of steady state equilibria, among which, some are Pareto efficient, some are not, depending on the speed of the resource harvesting, the more slowly, the more prone to be Pareto efficient. In the quadratic case (with additive log utility function and Cobb-Douglas production function), we prove that there is a unique steady state equilibrium, and there is an aggregate capital index (combining the physical capital and the natural capital), if the labor share is smaller than this index, then, the equilibrium allocation is Pareto efficient; if the labor share is bigger than this index, then, it's Pareto inefficient.
