The informational relevance of corporate social responsibility: evidence from DS400 index reconstitutions

This study examines the relationship between corporate social responsibility and financial performance by analyzing the intra‐industry wealth impact of additions and deletions to the Domini Social 400 index. Results from the event study analysis indicate that additions to the index generate a positive share price response for the announcement firm and a negative response by rival firms. The opposite reaction is observed for index deletions. Additionally, the share price response is more pronounced for informationally opaque industries. Our study highlights the importance of external monitoring agencies in providing meaningful information that helps resolve investor uncertainty regarding the quality of a firm's relationships with its primary stakeholders.

Prudent expectations equilibrium in economies with uncertain delivery

In an economy with private information, we introduce the notion of objects of choice as lists of bundles out of which the market selects one for delivery. This leads to an extension of the model of Arrow–Debreu that is used to study trade ex ante with private state verification. Under the assumption that agents are prudent, equilibrium is characterized by the fact that agents consume bundles with the same utility in states that they do not distinguish. This is a weaker condition than the restriction of equal consumption imposed by Radner (Econometrica 36(1), 31–58, 1968), therefore, some no trade situations are avoided and the efficiency of trade increases.     

信息披露、市场约束与银行风险承担行为

文章运用我国14家主要商业银行2000-2008年间的数据,实证研究了银行信息披露与其风险承担行为之间的关系,研究表明信息披露能否发挥其市场约束功能取决于相应的制度基础和市场环境,只有当金融体系的市场化程度较高,且银行能充分有效地披露其风险信息时,来自债权人的市场约束行动才能真正发挥对银行风险承担行为的约束作用.

A Generic Framework for Automated Multi-attribute Negotiation

Agents in a negotiation may have to negotiate multiple issues simultaneously. Automated multi-attribute negotiation provides an important mechanism for distributed decision makers to reach agreements on multiple issues. Moreover, it also furnishes the opportunity to reach “win–win” solutions. In this paper, we first provide a survey that synthesizes the research on multi-attribute negotiation. We discuss the limitations of the existing research and conclude that three key issues need further study: incomplete information, Pareto optimality, and tractability. We then present a generic framework for automated multi-attribute negotiation with two new mechanisms that address the above issues. Finally, we discuss the challenges and directions for future work.
