“财经周评”模式在《证券投资学》课程教学中的应用

证券公司及其他金融机构在业务开展过程经常对财经信息进行评论。《证券投资学》课程是经济金融专业的重要课程,能为学生提供未来工作岗位中所需的证券等金融基础知识。文章提出了采用＂财经周评＂的模式,把对财经信息的＂读写议＂方法应用到《证券投资学》课堂教学中的设想,并详细分析该模式特点、意义、实施步骤、实施过程中可能产生的问题及应对措施。《证券投资学》课堂中应用该教学模式,学生能够更好掌握证券知识和提高对财经信息的阅读、写作和评议的能力。     

Earnings Metrics,Information Processing,and Price Efficiency in Laboratory Markets

An enduring issue in financial reporting is whether and how salient summary measures of firm performance (“earnings metrics”) affect market price efficiency. In laboratory markets, we test the effects of salient earnings metrics, which vary in how they combine persistent and transitory elements, on investor information search, beliefs about value, offers to trade, and market price efficiency. We find that including transitory elements in salient earnings metrics causes traders to search unnecessarily for further information about these elements and to overestimate their effect on fundamental value relative to a rational benchmark. In contrast, separately displaying persistent elements in earnings increases the accuracy of traders’ value estimates. Prices generally reflect traders’ beliefs about value, and prices are most efficient when transitory elements are excluded from earnings metrics entirely. Our study contributes to research on salience effects in financial reporting by showing that including transitory elements in salient earnings metrics causes inefficient information search and biased beliefs about value that can aggregate to affect market prices. We also contribute to research in experimental markets by showing that redundant disclosure is not always beneficial; redundant disclosure of transitory earnings elements, in particular, appears to have negative consequences for investor behavior and market efficiency.     

环保背景下制造业上市公司投资效率分析——来自京津冀地区的数据

以2011~2012年在国内 A 股市场上市的130家京津冀地区现代制造业上市公司为样本,通过Richardson 模型对样本投资效率进行评分,并用内容分析法对企业环境信息披露程度评分,以此研究京津冀地区现代制造业上市公司环境信息披露对企业投资效率的影响。研究结果显示：环境信息披露程度评分与公司投资效率评分存在正相关关系,但相关系数较低,这表明企业环境信息披露行为对企业投资效率影响较小,且不会使得企业投资效率降低。

新型个人信息保护体系构建研究

大数据时代,传统的以“信息收集”规制为着力点的个人信息保护出现适法性困境,以“知情同意”为框架的机理失灵,个人信息的利用对象从直接个人信息逐渐向间接个人信息过渡,其财产价值凸显,新型个人信息财产权呼之欲出.立法应顺应数字经济的发展,构建合理新型个人信息体系.具体而言:纵向层面,以“宽进+删除权”为具体保护策略;横向层面...     

Vacancies and Rent Dispersion in a Stochastic Search Model with Generalized Tenant Demand

I model imperfect information, derive a downward sloping market demand curve, and explain vacancies in a partial equilibrium model of a rental housing market. Tenants can be completely described by an exogenous demand curve, perhaps arising from differences in income, preferred location, or tastes, and view vacant units based on a stochastic arrival of rental information. Free entry of these landlords induces excess rental housing capacity (equilibrium vacancies). I determine the equilibrium distribution of rents for vacant units, show that this rent distribution may be discontinuous, and explore the equilibrium vacancy rate to changes in exogenous parameters. The resulting characterization of equilibrium distributions of rents may be amenable to econometric modeling exploring the relationship between market rents and vacancies.
