Risky allocations from a risk-neutral informed principal

We study a model of informed principal with private values where the principal is risk neutral and the agent is risk averse. We show that the principal, regardless of her type, gains by not revealing her type to the agent through the contract offer. The equilibrium allocation transfers some ex-ante risk from one type of agent to the other. Despite the increase in the principal's surplus, allocative efficiency does not necessarily improve.

我国独立董事的现状及其困境分析

独立董事是我国移植西方国家的一项制度,可以说是我国公司治理中监事会制度“失灵”的产物。目前独立董事在我国上市公司中确实起到一定的作用,但他们基本上处于“边缘化”的困境状态,未能发挥其应有的职能。本文拟从实证和理论角度对此进行深入探讨和分析。     

结构异质性对中国能源高质量发展的影响研究

基于结构异质性对能源高质量发展影响的理论分析,使用稀疏主成分分析方法测度中国能源高质量发展水平,构建中国和八大经济区域面板分位数回归模型,实证研究了结构异质性对中国能源高质量发展的影响。结果表明：2003—2020年中国能源高质量发展水平有所提升,但仍存在明显的区域发展不平衡问题,西部地区和北部沿海地区的能源高质量发展水平更高。产业结构与能源高质量发展水平呈负相关关系,能源消费结构、资本配置结构与能源高质量发展水平呈正相关关系。     

基于遗传算法的核函数参数优化

核主分量分析是一种输入输出特征非线性变换技术。选择最优或接近最优的非线性变换核函数参数,使类的可分性测度最大,是KPCA应用于特征提取的关键。本文采用高斯变异遗传算法作优化技术,实现了KPCA和GA的集成,适合核函数参数的优化选择。仿真表明,该技术可行、有效。     

关于构建企业集团财务综合评价系统的思考

财务综合评价是以企业集团财务报告反映的财务指标为主要依据，对企业集团的财务状况和经营成果进行评价和剖析，反映企业集团在运营中的利弊得失、财务状况及发展趋势，为改进企业集团财务管理工作和优化经济决策提供重要的财务信息。企业集团可以从财务效益、偿债能力、营运能力、发展能力等四个方面建立全面完整的财务综合评价系统。

Materialism, status signaling, and product satisfaction

The consumer satisfaction literature has not, for the mos part, integrated individual values into the product evaluation process. Yet a comprehensive understanding of consumer satisfaction can best be attained by including both consumer and product factors. To demonstrate the usefulness of including individual values, this research focuses on one consumer value, namely, materialism. The authors empirically explore how this individual value is linked to consumers’ evaluations of products they have purchased. Using surveys, the authors collected data from a sample of college students (n=211) and a sample of adults (n=270). Across these two studies, using divergent samples and products, they find consistent evidence that materialism is negatively related to product satisfaction in product categories with high potential for status signaling, but unrelated to product satisfaction in product categories with lower potential for status signaling. The consumption goals that produce these product evaluations are empirically addressed Jeff Wang (jianfeng76@yahoo.com; PhD, City University of Hong Kong) is an assistant professor of marketing in the Faculty of Business at the City University of Hong Kong. This work was conducted when he was a doctoral student of marketing in the Eller College of Management at the University of Arizona. His research interests include social networks and consumer behavior, consumer satisfaction and well-being, materialism and consumption meanings, and consumer interests and public policy issues. His dissertation studies credit card debt as a socially embedded phenomenon and investigates how consumers leverage their interpersonal ties as they accumulate and repay their debt.
