Earnings management and abnormal returns: Evidence from the 1970–1972 Price Control Regulations

We examine the association between abnormal returns and earnings management in the context of price control regulations to test the construct validity of the earnings management model. Abnormal returns are used as a market–based measure, and discretionary accruals are employed to measure earnings management. Our results support the hypotheses that (1) price control regulations affect firms' security prices negatively, (2) firms make income–decreasing discretionary accruals to increase the likelihood of price increase approval, and (3) firms that are affected most negatively by the regulations manage earnings more aggressively. We conclude that the earnings management model we use in this study is capable of predicting opportunistic discretionary accruals.

从敦煌本《百行章》看唐初的法制思想

唐代的法制思想，主要有两大特征，即仁刑恤典和厉行法制。对此，学者们多从正史的角度加以探讨和分析。而从敦煌所出唐代蒙书《百行章》所述内容同样清楚地显示了唐初的法制思想的以上特点。这一研究可以起到补充正史的作用。     

On Sraffa's Standard commodity: is its price invariant with respect to changes in income distribution?

In his 1960 book, Sraffa suggested using a composite commodity,which he called the ‘Standard commodity’, to solveRicardo's search for an invariable measure of value, i.e., astandard capable of isolating the price movements of any othercommodity induced by changes in income distribution. The absencein Sraffa's book of an explicit proof of the invariance propertyof this standard gave rise to many misunderstandings about itsmeaning and its role as an invariable measure of value. In orderto clear up these questions, Bellino (On Sraffa's Standard commodity,Cambridge Journal of Economics, vol. 28, 121–32, 2004)has proposed a ‘proper’ definition of an ‘invariablemeasure of value’, showing that Sraffa's Standard commoditydoes fulfil the requirements of this definition. He claims thatthe fulfilment of this property (but not the constancy of its‘nominal’ price) qualifies the Standard commodityas an invariable measure of value. In this paper, a proof ofthe invariance of the price of the Standard commodity with respectto changes in income distribution is given, and the equivalenceof this property with Bellino's definition of invariance isshown.     

Sources of Bank Interest Rate Risk

We investigate bank stocks'sensitivity to changes in interest rates and the factors affecting this sensitivity. We focus on whether the exposure of commercial banks to interest rate risk is conditioned on certain balance sheet and income statement ratios. We find a significantly negative relation between bank stock returns and changes in interest rates over the period 1991–1996. We also find that bank characteristics measured from basic financial statement information explain bank stocks'sensitivity to interest rate changes. These results suggest that bank managers, analysts, and regulators can use this information to assess the relative risk exposure of banks.     

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。

武汉金融安全区模式设计与研究

金融安全与稳定直接关系到一个国家或地区的经济安全与社会稳定。一个地区 ,在突出的支付风险得以逐一化解之后 ,适时启动创建金融安全区工程 ,并以此全面提高金融监管水平 ,实现区域金融业持续稳健发展已经成为当前我们面临的重要课题。本文在论证武汉市开展创建金融安全区的必要性和可行性的基础上 ,提出了构建以武汉金安指数为核心的指标监测体系、具体创建规划以及相应运行规程。     

资金约束下供应商的融资模式及风险防范

当前,商品市场的竞争越来越明显地体现在商品供应链上面,而矛盾的焦点在于很多供应商受资金短缺的约束,已与上下游企业之间产生严重的不协调现象,进而影响到下游制造商或零售商的利润,最终导致整体上供应链利润减少。面对资金约束问题,供应商应积极动员上下游企业尽可能地采取经济援助策略,增强融资的风险防范能力。其基本模式主要有：企业预付款融资模式、企业直接投资融资模式、企业担保下的银行融资模式。并通过采用价格折扣、收益共享、供应链保险等方法规避风险,达到供应链条及供应链上各企业可持续发展的目的。     

绿色中药产业初见成效 发展任重道远——对汉中市部分中药产业重点发展县的调查

近年来,汉中市实施＂发展绿色产业,建设绿色汉中＂的战略,中药产业逐渐成为汉中经济发展新的增长极。为了解汉中中药产业的发展情况以及银行业机构金融服务支持情况,笔者先后深入勉县、留坝、佛坪等中药材生产形成一定规模的县域,采取与当地政府部门、银行业机构座谈,深入农户中药材种植基地和实地察看加工企业等方式进行了专题调研,分析了其中问题并提出相关建议。
