高管薪酬、股权激励与公司绩效的相关性检验

国内外理论界对于高管薪酬激励与公司绩效关系的研究尚未得出较为一致的结论,尤其是在高管薪酬与其自身持股比例、高管薪酬与公司股权集中度上,在实证结果中存在较大分歧。因此,如何把影响高管薪酬激励水平和公司绩效的种种因素合理的纳入模型中就显得尤为关键。在综述前人研究成果的基础上,将上证180和深证100指数中的成分股作为样本,通过多元回归分析检验我国大型上市公司高管薪酬、股权激励与公司绩效的相关性,从而在理论上为我国高管薪酬制度改革提供一定的理论依据和实证支持。     

Assessing the impacts of oil price fluctuations on stock returns in emerging markets

This paper investigates the effects of oil price shocks on stock market returns in emerging countries. It differs from previous works in three main aspects: i) we distinguish three groups of countries, the largest net-oil importing countries, the moderately oil-dependent countries, and the largest net-oil exporting countries; ii) The potential influence of bullish and bearish market conditions on the causal relationship between oil and stock returns is controlled for in our analysis; iii) The empirical investigation is based on an analysis of long-term correlation and a conditional multifactor pricing model. Using data from twenty-five emerging countries, our results suggest that oil price risk is significantly priced in emerging markets, and that the oil impact is asymmetric with respect to market phases.     

中国农村小额信贷供求状况分析

小额信贷自20世纪90年代以来在世界各地取得了巨大的发展和举世瞩目的成就,作为一种新型的金融方式,已经引起了全世界的广泛关注,正在逐渐得到重视和推广。小额信贷机构能够有效地为农村贫困人口提供小额贷款与其他金融产品,解决农村金融的困境。但截至目前,小额信贷的发展状况仍然难以满足社会经济发展的要求。本文分析我国农村小额信贷的供求矛盾,探讨其发展缓慢的深层次原因,并提出相对应的政策建议。     

Poverty identification: practice and policy implications in Vietnam

To identify poor households, the government of Vietnam applies a combination of proxy means tests and quick collection of income data. This paper examines how well the government's poverty identification reaches the really poor in Vietnam. It is found that there is a large difference between the poverty rate for provinces and districts reported by the government and the rates estimated using expenditure and income data from independent household surveys. There is also a large difference between the poverty status of households identified by local authorities and the poverty status identified by income or expenditure data. More than 50 per cent of the poor households identified by local authorities are not poor in terms of income or expenditure measures. A better identification approach would be to use only proxy means tests and not income data collected using the simple questionnaire.     

我国经济发展水平与劳动力就业数量关系研究——兼论我国劳动力资源是否过剩

我国劳动力对经济发展而言,其生产率高于资本,因而经济发展对劳动力就业的促进作用逐渐减弱（经济增长的就业弹性逐渐变小）。据测算,我国2013年以前劳动力就业压力很大,2015年以后劳动力又会供不应求。所以,我国未来经济发展中,2014年前后应采用不同的产业结构调整策略来充分满足劳动力就业的要求。     

Managerial ownership and firm performance: Evidence from China's privatizations

We examine the relationship between managerial ownership and firm performance for a sample of Chinese State-owned enterprises (SOEs) privatized over the period 1992-2000. The results indicate that managerial ownership has a positive effect on firm performance. Although return on assets (ROA) and return on sales (ROS) decline post-privatization, firms with high managerial ownership and, specially, high CEO ownership, exhibit a smaller performance decline. The difference is highly significant, with or without controlling for residual state ownership and changes in the firm's operating environment. We also find that the influence on firm performance becomes less significant at higher levels of CEO ownership. In contrast, performance continues to increase with managerial ownership. This finding suggests that, beyond a certain point, the distribution of shares would be more effective if extended to the whole management team instead of being limited to the chief executive.     

ETF arbitrage: Intraday evidence

We use two extremely liquid S&P 500 ETFs to analyze the prevailing trading conditions when mispricing allowing arbitrage opportunities is created. While these ETFs are not perfect substitutes, our correlation and error correction results suggest investors view them as close substitutes. Spreads increase just before arbitrage opportunities, consistent with a decrease in liquidity. Order imbalance increases as markets become more one-sided and spread changes become more volatile which suggests an increase in liquidity risk. The price deviations are followed by a tendency to quickly correct back towards parity.     

供应链金融利益主体的多阶段博弈研究

现代经济中,金融在资源配置方面发挥的作用明显不足,出现严重的资源浪费和供需错配现象,加剧了中小企业面临的融资难问题.本文从供应链金融的内涵切入,建立以利益相关者为主体的融资量化模型,利用多阶段博弈理论对企业不同模式下的成本收益进行检验,结果表明:供应链金融在实现上、下游各利益相关者个体的最优化的同时,也可有效促使供应链整体的利益最大化、实现高效运作和价值增值,全面实现链上企业间的资源共享、互利共赢.
