Does preventive regulation reduce stock price synchronicity? Evidence from Chinese annual report comment letters

Based on a sample of Chinese A-share listed firms from 2015 to 2018, this paper studies the impact of annual report comment letters (ARCLs) on firm stock price synchronicity. We find that after firms receive ARCLs, their stock price synchronicity decreases. Moreover, the longer the ARCLs and the more negative the ARCLs’ tone, the lower the resulting stock price synchronicity. The mechanism test shows that after firms receive ARCLs, the firms’ information disclosure increases in quantity and quality, external media attention increases, and the firms’ governance improves, reducing their stock price synchronicity. Further research shows that this negative association is more significant in firms with higher information asymmetry. This paper shows that the ARCL, an innovative application of the capital market supervision philosophy, is conducive to improving the quality of listed firms and to the healthy development of the capital market.     

财政预决算信息公开问题研究综述

本文从预决算信息公开的概念、重要性、评估、建议四个方面,对预决算信息公开问题进行综述。预决算信息公开在保障公众知情权,加强监督、防治腐败,加快政府转型、促进“服务型”、“责任型”政府建设,推动政治体制改革、提高政府治理能力,实现“中国梦”方面具有重要意义。预决算信息公开的评估主要是根据具体原则要求,设立相对应的评价指标体系进行评估。建立预算公开的顶层制度设计、完善预算公开的相关法律法规、提高预算信息公开的质量和获取的便利性、引入公民参与机制等措施能够提升预决算信息公开的程度。通过综述,得出,即重视和分析预算、决算两方面信息的重要性,并对其进行对比绩效分析来促进财政信息公开。     

政府审计信息披露质量评价体系构建

政府审计信息公开是政务信息公开的一个重要方面,审计署公开审计信息一方面提高审计监督的透明度,另一方面保障公民、法人和其他组织对审计的知情权、参与权和监督权。文章阐述了政府审计信息披露的理论基础和现状,并在此基础上对审计署近几年公布的审计信息公开工作报告进行加工整理,进而对政府审计信息公开工作报告存在的问题做出尝试性的归纳和总结。最后,提出中国政府审计信息披露质量评价指标体系由及时性、完整性、准确性、客观性、重要性及清晰性等六个方面质量特征构成。     

Portfolio concentration and performance of institutional investors worldwide

Using data on security holdings for 10,771 institutional investors from 72 countries, we test whether concentrated investment strategies result in excess risk-adjusted returns. We examine several measures of portfolio concentration with respect to countries and industries and find that portfolio concentration is directly related to risk-adjusted returns for institutional investors worldwide. Results suggest, in contrast to traditional asset pricing theory and in support of information advantage theory, that concentrated investment strategies in international markets can be optimal.     

Credit market imperfections,labor markets,and leverage dynamics in emerging economies

Emerging economies (EMEs) have different credit and labor market structures relative to advanced economies. We document that economies with larger self-employment shares tend to exhibit less countercyclical leverage dynamics. We build a model where formal credit markets, input credit relationships, and the structure of labor markets interact that (1) captures a comprehensive set of EME business cycle regularities and (2) rationalizes our new fact. The interaction between firms’ net worth, interfirm input credit, and self-employment underlying our framework is critical for explaining our fact and is supported by the data.     

金融消费者保护:基于委托代理模型的研究

由于金融产品的无形化、专业化、复杂化等特性,金融消费者在市场交易中处于更弱势的地位,使得金融消费者需获得更强的保护措施.本文从委托代理模型的角度出发,对金融消费者在金融市场的地位进行分析,从理论上对金融消费者权益损害的问题和可提供的保护机制进行研究,从而为金融消费者保护实践提供指导.     

Dynamics of analysts' coverage and the firms' information environment

The main goal of this paper is to study analysts' coverage of stocks. Through a series of ordered probit regressions the paper studies the relationship between changes in coverage and the information environment of a firm.Coverage decreases on average with higher errors in estimation. The data also shows that coverage is less likely to decrease for physically large firms, but more likely to decrease for firms with high lagged market value. Higher past revisions to the predictions also decrease coverage, showing a real cost of uncertainty.     

个人金融信息保护及监管研究 ——基于金融集团经营模式视角

近年来,我国金融综合经营趋势日益明显,金融集团业务具有内部关联性、隐蔽性等特点,金融集团为减少成本,增强竞争力,利用控股优势,在集团内部共享客户信息成为一种常态,但却呈现出一种无监管的状态。金融集团个人金融信息保护既存在一般金融机构在个人金融信息保护方面显现的共性问题,还存在集团模式下所引发的特殊问题,究其原因,主要在于法律法规缺位、监管不力、金融机构自律不够等。本文针对这些问题,提出了构建我国金融集团个人金融信息保护框架的构想。     

Competing institutional logics of information sharing in public services: Why we often seem to be talking at cross-purposes when we talk about information sharing

Sharing information and data across organizational boundaries has proved hard to achieve. This is, in part, because we have framed the problem, and possible solutions, in one of three conflicting ways that draw on powerful institutional logics: design, governance and enculturation. Five strategies for addressing this conflict are presented—contingency, combination, conflict, ambiguity and synthesis. The conclusion links the problem of information sharing to the paradoxical nature of information.     

Differently motivated exchange traded fund trading activities and the volatility of the underlying index

This paper examines the correlations between two types of a market index's volatility and three trading motives of the index's exchange traded funds (ETFs). We find that ETF trading driven by belief dispersion is highly correlated with both the variance in efficient price innovations (VEPI) and the index's total volatility. Privately informed ETF trading is closely connected to the VEPI but not the total volatility, while liquidity ETF trading explains the total volatility but has little power in explaining the VEPI. Moreover, the leading ETF dominates smaller ETFs in explaining both types of volatility and often has more explanatory power than control variables.
