对股权分置改革对价问题的理论分析

解决股权分置问题，让非流通股变为可以流通的股份，必然存在非流通股股东为换得流通权而向流通股股东支付对价的问题。为协调流通股股东和非流通股股东两者的利益，非流通股股东必须支付一定的对价，作为取得流通权的成本。对价的高低不仅直接影响授资者的利益，而且是股权分置改革成败的关键。对价方式多样化为授资者提供了更多的市场机会。     

Do social factors influence investment behavior and performance? Evidence from mutual fund holdings

We study the economic significance of social dimensions in investment decisions by analyzing the holdings of U.S. equity mutual funds over the period 2004–2012. Using these holdings, we measure funds’ exposures to socially sensitive stocks in order to answer two questions. What explains cross-sectional variation in mutual funds’ exposure to controversial companies? Does exposure to controversial stocks drive fund returns? We find that exposures to socially sensitive stocks are weaker for funds that aim to attract socially conscious and institutional investor clientele, and they relate to local political and religious factors. The financial payoff associated with greater “sin” stock exposure is positive and statistically significant, but becomes non-significant with broader definitions of socially sensitive investments. Despite the positive relation between mutual fund return and sin stock exposure, the annualized risk-adjusted return spread between a portfolio of funds with highest sin stock exposure and its lowest-ranked counterpart is statistically not significant. The results suggest that fund managers do not tilt heavily towards controversial stocks because of social considerations and practical constraints.     

Altruism and egoism in investment decisions

We provide survey evidence that personal values have an impact on individual investment decisions, in particular preferences for socially responsible investing. Our findings show that there is a positive link between altruistic values and the relative importance of social responsibility. This effect is stronger when individuals believe that they can make a positive social or environmental impact with their investments, or when they feel morally obliged to invest responsibly. If altruistic individuals associate responsible investments with higher returns, it decreases their motivation to invest responsibly. Egoistic values are negatively associated with the decision to invest responsibly, unless individuals associate responsible investing with higher returns.     

Underperformance of Actively Managed Portfolios: Some Behavioral Insights

Abstract

Two glaring anomalies in investment management are apparent: (1) after fees, active portfolio managers do worse than market indices, and (2) clients continue to pay for services they don’t receive. The purpose of this paper is to offer explanations of these anomalies from a behavioral perspective. We explore some of the cognitive biases that perpetuate active management and subsequent underperformance, including herding, disposition, and endowment effects, as well as conservatism and status quo biases, overconfidence, and agency problems. Investors’ continued use of active managers despite persistent disappointing returns is attributed to being victims of framing effect, hot-hand fallacy, lack of knowledge as well as intimidation or insecurity, and status quo bias. We propose some ways that portfolio managers and investors could improve their decision making.     

高管团队异质性、团队冲突与企业绿色绩效——差异化CEO领导风格调节下的整合分析框架

基于高阶梯队等理论，从高层管理团队异质性等要素整合分析视角切入，在探讨高层管理团队驱动企业绿色绩效作用机制的基础上，尝试构建差异化CEO领导风格调节下高管团队（TMT）异质性、团队冲突与企业绿色绩效的理论模型；通过层次回归分析、Bootstrap等方法实证检验异质性高层管理团队的作用机理和边界。研究结果显示：①TMT异质性、任务冲突能显著提升企业绿色绩效，且任务冲突在TMT异质性与企业绿色绩效的关系中起部分中介效应，而关系冲突显著降低企业绿色绩效。多元化构成的高层管理团队拥有更多差异化思想，这些观点通过高层管理团队成员不断分析整合后作用于绿色绩效，而成员间“对人不对事”的关系冲突会弱化该过程，进而对绿色绩效产生负向影响；②变革型CEO领导风格负向调节任务冲突与企业绿色绩效的关系，表明CEO适度简政放权，指导、关怀和保障高管团队成员充分表达观点非常重要。交易型CEO领导风格负向调节关系冲突与企业绿色绩效的关系，说明CEO通过奖惩激励，降低高层管理团队情绪冲突，提升团队凝聚，是推动绿色转型的重要举措。
