股市波动、金融政策和宏观经济关系研究——基于因子VAR模型

通过因子分析从诸宏观经济变量中提取了金融政策因子和宏观经济状态因子,建立了基于VAR的股价波动、金融政策和宏观经济三变量回归模型。研究表明：金融政策影响股价的表现,而宏观经济状态对股价、股价对金融政策和宏观经济状态的影响均不显著;基于标准差的VAR（5）模型相对于基于收益率的VAR（3）模型能更好地刻画股市波动与金融政策、宏观经济三者之间的关系。     

CEO与CFO股权激励的治理效应之比较:基于盈余管理的实证研究

在西方发达国家,CFO与CEO拥有相同的法律地位,负有监督CEO的责任,在公司治理结构中拥有重要的地位。本文从盈余管理角度研究我国CFO股权激励的公司治理效应,并比较CFO与CEO股权激励的公司治理效应,发现:尚未实施股权激励计划的公司,其CFO股权和期权占总薪酬比率与盈余管理呈负相关关系,而实施股权激励计划的公司,其CFO股权和期权占总薪酬比率与盈余管理的负相关关系显著变弱;尚未实施股权激励计划的公司,其CFO股权和期权占总薪酬比率对盈余管理抑制的程度显著小于CEO。这表明,正式实施股权激励会诱发盈余管理行为,其它类型的CFO持股则会抑制盈余管理行为,并且CFO股权激励的积极治理效应显著小于CEO。     

Spillovers in Exchange Rates and the Effects of Global Shocks on Emerging Market Currencies

This paper provides an investigation into the spillover effects of exchange rate returns and volatility for developed and emerging market currencies, using data from 1997 to 2011. The results suggest that spillovers in exchange rate returns have increased steadily over time, in moderate reaction to economic events. In contrast, spillovers in total observed volatility (measured by squared returns) react more strongly to economic events, and this transmission has remained at a relatively high level since the global financial crisis. Furthermore, over the course of time, global shocks would appear to account for a larger proportion of aggregate exchange rate volatility (and the relative importance of domestic shocks has declined). The paper also considers whether the increase in volatility spillover is due to sudden shocks, or whether it is due to changes in the stochastic trend of the underlying volatility process. The results suggests that in most cases, this increase is due to sudden shocks, however, in certain instances country‐specific events may perpetuate changes to the trend of the underlying volatility spillover.     

中国与东盟五国股市投资组合的风险和收益——基于MV和M-LPM模型的实证研究

选取2003年1月至2011年12月间中国和东盟五国股市的市场指数数据样本,分别基于MV和M-LPM模型构造等权重组合、最小方差组合和最大夏普比率组合,比较不同模型和不同投资组合的风险和收益率,实证结果表明构造中国与东盟五国股市投资组合与仅投资国内A股相比可以显著提高风险收益率。     

Trade policy and specialization in developing countries

This paper examines the impact of trade policy on specialization patterns in ten Latin American countries over the period 1985–1998. These countries are natural case studies because in the last decades they implemented comprehensive trade liberalization programs, both generally and preferentially, starting from relatively high tariff protection levels. Our econometric results suggest that reducing own most favored nation tariffs is associated with increasing manufacturing production specialization. Furthermore, we find that preferential trade liberalization and differences in the degree of unilateral openness have resulted in increased dissimilarities in manufacturing production structures across countries. These results are robust across specialization measures and estimation methods.

省际人力资本存量的估算——以江苏省为例

知识经济时代,人力资本对经济发展的作用越来越被人们重视,但对人力资本的如何度量的研究却相对薄弱,本文以江苏省为例,通过估算江苏省各级受教育程度人员总数、各级受教育程度人员的从业率,计算出各级受教育程度的从业人员数,再用受教育年限法估算出了江苏省人力资本存量,并对江苏省人力资本的发展状况和人力资本结构等进行了简要的分析。     

美国劳工组织对中美贸易关系的影响——以PNTR案和货币操控案说起

中美贸易关系历来受多种因素影响,美国国内劳工组织在中美贸易摩擦的两个典型个案中起到了一定的影响。其行动的一般规则及目的需要进一步研究及分析,从而利用这些规则来为中美贸易关系润滑,减少不利因素最终提高贸易关系成功的可能性。
