改变盘点思维,降低物流成本

企业集团内的生产企业与销售企业委托同一物流中心管理库存商品时,为了便于对库存商品进行实地盘点,往往要求将不同企业的同种库存商品分开保管,但是,分开保管的结果却增加了物流成本。为此,有必要改变传统的盘点思维,引入现代管理信息系统,实现不同企业同种库存商品共享同一场地的管理方式,以降低物流成本。

个人住房贷款的风险与防范

近年来,商业银行把个人住房贷款看作是优质贷款品种,因此一直大力发展该项业务。但是,根据国际经验,个人住房贷款的风险暴露期通常为3-8年,中国个人住房贷款可能刚开始进入到风险暴露期。因此正确认识并努力防范当前个人住房贷款业务存在的风险尤为重要。本文深入分析了个人住房贷款的风险,如假按揭风险、信用风险、流动性风险等五种风险,并提出了防范风险的对策。     

浅析上市公司管理层股权激励类型及其对企业绩效的影响

管理层股权激励已经在各国的管理实践中得到广泛的运用,企业委托人为了解决与代理人之间的矛盾,对管理层采取了这种长期激励的方式。同时,管理层股权激励的效用可以用企业绩效来测度,因此,管理层股权激励应与企业绩效挂钩。本文分析了上市公司中的股权激励类型及优缺点,并对各种股权激励模式对企业绩效所产生的影响进行了研究。     

中国和印度股市波动性的比较研究

作为“金砖四国”中的成员,中印两国股票市场具有较强的可比性。比较分析金融危机发生后两国的股市波动性特征,对中国股市发展具有理论和现实双重借鉴意义。文章利用ARCH族模型对上证综合指数和印度孟买30指数日收盘价数据展开实证研究,比较解析金融危机发生后中印两国的股市波动性特质,分析表明可变性和波动集簇性是两国收益率波动均呈现出的明显特质,而且印度比中国有更强的显示度;此外,中印两国股市收益正的风险溢价表现不显著;杠杆效应在上证综合指数收益率和印度孟买30指数收益率中均有体现,而且杠杆效应在印度股市的影响要高于中国股市。这对于确保中国股票和证券市场持续、稳定、强劲发展具有显著的理论说服力及重大的实践意义。     

The relationship between stock prices and exchange rates in South Africa and Nigeria: structural breaks analysis

The relationship between stock prices and exchange rates has continued to generate interest from both the academia and financial industry players for many years. This study conducts an empirical investigation into the relationship between stock prices and exchange rates for the two largest economies in Sub-Saharan Africa – South Africa and Nigeria. Our methodology accounts for structural breaks in the data and the long-run relationship between stock and foreign exchange markets. The results of multivariate causality tests with structural breaks showed that causality runs from exchange rates to domestic stock prices in Nigeria (flow channel) while in South Africa, no causality exists between domestic stock prices and exchange rates. The results also reveal that there is causality from the London stock market to both countries’ stock markets, thus showing that international stock markets are driving both the Nigerian and South African stock markets.     

Oil shocks,policy uncertainty and stock returns in China

This paper examines the interdependence of China's policy uncertainty, the global oil market and stock market returns in China. A structural VAR model is estimated that shows that a positive shock to economic policy uncertainty in China has a delayed negative effect on global oil production, real oil prices and real stock market returns. Shocks to oil market‐specific demand significantly raise China's economic policy uncertainty and reduce the real stock market returns. As measured by a spillover index, the interdependence between these variables has been rising since 2003 as China's influence in the oil market has increased. An equivalent spillover index calculated for the US is smaller and has been largely flat over time.     

Failures to Deliver,Short Sale Constraints,and Stock Overvaluation

Studying a large sample of publicly available data on failures to deliver, we find that stocks reaching threshold levels of failures become significantly overvalued. Where short sale constraints are especially binding, we report extreme overpricing and subsequent reversals. These findings support the overvaluation hypothesis, although the mispricing is likely to be difficult to arbitrage because of extreme shorting costs. In addition, threshold stocks with low short interest become more overvalued than threshold stocks with high short interest. This suggests that the level of short interest reflects supply‐side effects when the examination conditions on the difficulty of borrowing shares.
