Performance ratio-based coherent risk measure and its application

Utilizing a specific acceptance set, we propose in this paper a general method to construct coherent risk measures called the generalized shortfall risk measure. Besides some existing coherent risk measures, several new types of coherent risk measures can be generated. We investigate the generalized shortfall risk measure’s desirable properties such as consistency with second-order stochastic dominance. By combining the performance evaluation with the risk control, we study in particular the performance ratio-based coherent risk (PRCR) measures, which is a sub-class of generalized shortfall risk measures. The PRCR measures are tractable and have a suitable financial interpretation. Based on the PRCR measure, we establish a portfolio selection model with transaction costs. Empirical results show that the optimal portfolio obtained under the PRCR measure performs much better than the corresponding optimal portfolio obtained under the higher moment coherent risk measure.     

债务结构、创新投资与中小企业成长性研究——基于交互效应模型

本文以2010～2014年的中小板上市公司数据作为研究对象,采用层次回归方法检验假设。研究结果表明：企业的债务结构与成长性有负相关关系,创新投资与中小企业的成长性有正相关关系,并且随着中小企业的创新投资的增加,债务结构对中小企业的成长性的负向影响作用进一步加大。     

控制权转让、产权性质与公司绩效

本文以2003—2011年A股发生终极控制人变动的上市公司为样本,考察了四类控制权变动对公司绩效的影响。结果发现:(1)国有转民营和民营转国有都能显著提高公司绩效,而国有转国有和民营转民营对公司绩效的提高并不显著;(2)民营转国有对公司绩效的提高源于隧道效应的减弱,而国有转民营对公司绩效的提高则是隧道效应的减弱和经理人代理问题的降低两方面共同作用的结果。以上结论说明,产权性质的改变在控制权转让过程中起到了积极的作用,不同所有制结构在治理问题上各有优缺点:国有企业往往面临更为严重的经理人代理问题,而民营企业的大股东隧道效应更为严重。所有权性质的转变导致治理形式的转换,新的治理形式克服了原先治理形式的缺点,从而提高了效率。本文结论有利于缓解"国进民退"的争论,同时为进一步推进混合所有制改革提供了经验证据。

Consumer Preference for Meat in China: A Case Study of Beijing

We analyze Chinese consumer preferences for pork shoulder-cut attributes during the recent period of fluctuating food prices caused by production and market anomalies. Consumers were randomly sampled in Beijing, China. Results indicate that consumers place great importance on where they purchase pork products as well as on whether the animals are raised with organic feed. Whether pork is fresh or previously frozen does not appear to matter much to consumers. This may provide partial support for the Chinese government's policy of using frozen pork reserves to stabilize pork prices.     

Portfolio Distortions Among Institutional Investors: Evidence from China

The behavior of institutional investors often deviates from established personal or social norms; this deviation may reflect either an informational advantage or a psychological bias. In this paper, we investigate the reasons Chinese mutual funds hold lottery-type stocks, which are characterized by low average returns and high risk. We find that funds at the aggregate level do not exhibit a propensity to gamble, but when they do gamble, they earn abnormal returns on lottery-type investments. Gambling-related outperformance is greater among held firms with characteristics that enable fund managers to obtain more informational advantages. Our results suggest that portfolio distortion is driven by the ability of managers to capitalize private information rather than by behavioral bias.     

Does option trading convey stock price information?

After executing option orders, options market makers turn to the stock market to hedge away the underlying stock exposure. As a result, the stock exposure imbalance in option transactions translates into an imbalance in stock transactions. This paper decomposes the total stock order imbalance into an imbalance induced by option transactions and an imbalance independent of options. The analysis shows that the option-induced imbalance significantly predicts future stock returns in the cross section controlling for the past stock and options returns, but the imbalance independent of options has only a transitory price impact. Further investigation suggests that options order flow contains important information about the underlying stock value.     

美国、加拿大金融情报中心特点及对我国的启示

尽管我国与美国、加拿大属于不同法系,但是由于大陆法系和英美法系反洗钱立法趋同的背景,以及美加具有与我国类似的幅员辽阔等特点,因此研究两国金融情报中心的特点对于我国强化反洗钱工作大有裨益.加拿大严格的信息披露制度、美国的严厉的行政处罚手段、美加两国反洗饯报告主体的广泛性以及两国注重解决防卫性报送的思路等都值得我国学习和借鉴.
