衡量房价合理回归标准的思考

房价合理回归就是要通过对房价的调控使其回到合理水平,它体现了中央政府对房价调控的决心和信心,反映了城镇居民的心声和期待。判断房价是否合理回归,一看房价是否与城镇居民收入相适应;二看房价是否与成本和合理利润相匹配。要促进房价合理回归,必须坚持房价调控政策不动摇,巩固房价调控成果;努力降低商品住房成本,制止开发商暴利行为;理顺收入分配关系,增加城镇居民收入;加大保障性住房建设力度,构建住房保障体系;抑制住房投机需求,维护市场秩序,以实现房价调控目标。     

收益率差异视角下股票流动性与资本结构关系的再检验

本文在股票收益率差异视角下,选择2000年1月到2015年12月期间中国沪、深市场307家上市公司数据,采用单方程估计法和联立方程组系统估计法研究我国上市公司股票流动性与资本结构的相互影响;并分别从股权分置改革、股权再融资、牛熊市行情三个方面对二者关系的变化与差异进行深入分析。结果表明：股票流动性与资本结构之间存在显著的负向关系,并且随着股票收益率水平的提高,负向影响越来越明显;股权分置改革后、满足再融资资格的上市公司以及牛市行情下两者的相互影响更显著。

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.

The determinants of the volatility of returns on cross-border asset holdings

Using both panel and cross-sectional models for 28 industrialized countries observed from 2001–2009, we report a number of findings regarding the determinants of the volatility of returns on cross-border asset holdings (i.e., equity and debt). Greater portfolio concentration and an increase in assets held in emerging markets lead to an elevation in earning volatility, whereas more financial integration and a greater share held in Organization for Economic Cooperation and Development countries and by the household sector cause a reduction in the return volatility. Larger asset holdings by offshore financial corporations and non-bank financial institutions cause higher market volatility, although they affect volatility in the equity and bond markets in the opposite way. Overall, both panel and cross-sectional estimations provide very similar results (albeit of different magnitude) and are robust to the endogeneity problem.     

Rewarding customers who keep a product: How reinforcement affects customers' product return decision in online retailing

A lenient product return policy represents the status quo of current return management practice in online retailing because it increases customers' order tendency. However, at the same time, many customers tend to return products under this policy, which incurs considerable costs for retailers. The present research introduces a keep reward (i.e., providing incentives to keep a product) as a new promotion strategy to improve the conventional lenient policy. Drawing on operant conditioning, the authors propose and test the reinforcing effect of a keep reward on customers' keep decision, compared to the conventional lenient policy. Results of a qualitative pilot study suggest that a keep reward is generally feasible in online retailing practice, especially in the low‐ to mid‐price segment and with rewards that are linked to future purchases. Two experimental studies verify the positive effect of a keep reward. Study 1 shows that it substantially increases keep intention compared to a conventional lenient policy. Study 2 shows that the effect on keep intention is moderated by customers' online shopping frequency, and this moderating effect is mediated by repurchase intention. In particular, the keep reward is most effective among frequent shoppers because they are more inclined to repurchase and thus, benefit from the reward. In summary, both studies support the keep reward as a valuable add‐on to the conventional lenient policy because order intention remains comparably high, while keep intention is higher. Theoretical implications and recommendations for online retailers on how to implement a keep reward in different industries are discussed.     

Disappearing Dividends: Implications for the Dividend–Price Ratio and Return Predictability

The conventional dividend–price ratio is highly persistent, and the literature reports mixed evidence on its role in predicting stock returns. We argue that the decreasing number of firms with a traditional dividend‐payout policy is responsible for these results, and develop a model in which the long‐run relationship between the dividends and stock price is time varying. An adjusted dividend–price ratio that accounts for the time‐varying long‐run relationship is considerably less persistent. Furthermore, the predictive regression model that employs the adjusted dividend–price ratio as a regressor outperforms the random‐walk model. These results are robust with respect to the firm size.     

试析不当得利返还请求权与其他请求权的关系

不当得利请求权和民法上的其他请求权之间的关系问题，即是一个理论问题，也是一个实务问题，不仅涉及民法各项制度的功能体系，也事关不当得利返还请求权在处理民事案件中作用的发挥。以财产上的请求权发生的基础为核心，不当得利与合同、无因管理、物的返还、侵权行为等之间的关系的适用性，仍是实践中存在的突出问题。我们应承认不当得利返还请求权的独立性，并在此基础上承认它与其他财产上请求权可能发生的竞合，这样有助于民法各项制度的功能协调，有利于更加充分地实现民法维护公平正义这一根本理念。
