养老基金最低收益保证制度下的最优资产配置——来自中国1998-2008年数据的模拟分析

文章主要研究养老基金最低收益保证制度及其框架下的资产配置问题.利用鞅方法创新性地给出了最优资产配置策略,随后分析了最低收益保证制度对最优资产配置的影响.结果表明,外部机构的利润分享比例越大,保证额度越高,养老基金投资风险资产的比例越高,但随着时间的推移,其风险投资将逐步降低.最后,文章利用所得结论为我国设立最低收益保证制度提供了建议:即我国应设立相对额度的最低收益保证制度;应由政府部门或非盈利机构提供这种最低收益保证,且不宜采取利润分享原则;保证额度应适度,过高会导致养老基金的投资风险过高,而过低则达不到稳定退休者收入的效果.

特质风险能够被定价吗？——基于“特质波动之谜”现象的文献评述

传统的资产定价理论认为特质风险不应被定价,即便无法完全分散掉,与股票收益也应是对应权衡关系。但AHXZ（2006,2009）发现的＂特质波动之谜＂现象对标准金融学理论再次提出严峻的挑战,也使得公司特质风险定价行为逐渐成为金融经济学研究的新兴领域。本文从特质风险的测度、＂特质波动之谜＂现象的实证检验、异质性现象的形成机理三个方面进行研究综述,并提出进一步的研究展望,从而为今后研究提供借鉴和参考之用。

Employee stock ownership and financial performance in European countries: The moderating effects of uncertainty avoidance and social trust

This study investigates how the effect of employee stock ownership on financial performance may hinge on the diverse cultural and societal contexts of European countries. Based on agency and national culture theories, we hypothesize that the positive relationship between employee stock ownership and return on assets (ROA) is stronger in those nations with lower uncertainty avoidance and higher social trust. Using a multisource, time‐lagged, large‐scale dataset of 1,741 firms from 21 countries in Europe, our multilevel, random coefficient modeling analysis found evidence for these hypotheses, suggesting that uncertainty avoidance and social trust serve as important contextual cues in predicting the linkage between employee stock ownership and financial performance. Our supplemental analysis with distinction between the managerial and nonmanagerial employee stock ownership further indicates managerial employee stock ownership has a direct positive effect on ROA. Although nonmanagerial employee stock ownership had a nonsignificant association with ROA, the relationship was positive and significant when uncertainty avoidance was low and social trust was high. This research contributes to the existing literature by illuminating some of the contextual influences altering the effectiveness of employee stock ownership. Our findings also offer practical suggestions for effectively using employee stock ownership.     

中国创业板IPO首日超额收益研究

本文以58家创业板IPO公司为样本,采用类比估价模型来估计新股的内在价值。实证研究结果表明,我国创业板IPO首日超额收益源于二级市场溢价,一级市场抑价不显著;上市首日换手率、上市首日涨跌幅以及市场指数收益率显著影响我国创业板IPO首日超额收益。在此基础上,本文结合海外创业板市场经验以及我国创业板市场表现,给出了相关政策建议,对创业板市场参与者提供了可参考的投资策略。

非住宅建设用地使用权续期规则的思考

研究目的:分析非住宅建设用地使用权续期活动的规则与性质,提出完善续期规则的建议。研究方法:规范分析法,比较分析法。研究结果:非住宅建设用地使用权的续期规则存在疏漏,使续期申请的起止期间难以清晰界定,以私法视角理解续期活动也不妥当。研究结论:续期是申请人取得重新设立的建设用地使用权的过程,因此要求在续期过程中必须清晰界定续期权利的设立与灭失期间,保证续期或救济得以顺利进行。续期也是获得行政特别许可的结果,应当采用协议出让方式予以确认。     

How Does Stock Market React to Dividend Surprises? Evidence from Emerging Markets of India and Russia

In this article the authors empirically investigate information content of dividends announcements and average reaction of emerging markets of India and Russia to dividend surprises on the postcrisis period 2010 to 2014. The study applies an analysts’ expectations-based approach rarely used in academic literature. The authors conclude that the Russian market on average reacts negatively to good and bad dividend surprises; good dividend surprises on average trigger positive abnormal returns on Indian stocks, whereas bad and no surprises are associated with negative reactions of the Indian market. Results of the study are discussed from the perspective of dividend signaling theory, market efficiency, and investor behavior.
