China＇s Energy Strategy in the Twenty-first Century

I. Introduction As the biggest developing country, China’s energy consumption has increased substantially. China is now the second largest energy consumer in the world and its primary energy consumption accounts for 13.6 percent of the world total. In the global energy market, China seems to have an endless appetite for oil and gas. China depends on imports for more than 40 percent of its oil. According to an estimation by British Petroleum (BP, 2005), from 2000–2004, China’s oil consum…     

Understanding the perpetration of employee computer crime in the organisational context

While hackers and viruses fuel the IS security concerns for organisations, the problems posed by employee computer crime should not be underestimated. Indeed, a number of IS security researchers have turned their attention to the ‘insider’ threat. Of this group, several focus on the offender, either in terms of a series of attributes required for perpetration, or with reference to forms of safeguards aimed at negating such behaviour. These studies are complemented by those texts which examine the organisational context in which rogue employees commit computer crime. Currently, however, there has been a lack of insight into the relationship between the offender and the context, during the commission process. To address this deficiency, two criminological theories are advanced. This paper illustrates how the theories, entitled the Rational Choice Perspective and Situational Crime Prevention, can be applied to the IS domain, thereby offering a theoretical basis by which to analyse the offender/context relationship during perpetration. By so doing, practitioners may use these insights to inform and enhance the selection of safeguards in a bid to improve prevention programmes. Furthermore, the importation of the Rational Choice Perspective and Situational Crime Prevention into the IS field opens up potentially new areas for future research.     

Unobservable heterogeneity and rational learning: Pool-specific versus generic mortgage-backed security prices

Previous mortgage prepayment and valuation models assume that two mortgage pools with the same observable characteristics should behave indistinguishably. However, even pools with apparently identical characteristics often exhibit markedly different prepayment behavior. The sources of this heterogeneity may be unobservable, but we can infer information about a pool from its prepayment behavior over time. This article develops a methodology for using this information to calculate pool-specific mortgage-backed security prices. Knowledge of these prices is important both for portfolio valuation and for determining the cheapest pool to deliver when selling mortgagebacked securities. We find that unobservable heterogeneity between mortgage pools is statistically significant, and that pool-specific prices, calculated for a sample of outwardly identical mortgage pools between 1983 and 1989, may differ greatly from any single representative price.     

The Export Market Pattern of China＇s Textiles and Apparel in Post-quota Regime

On the basis of studying the status of China＇s textiles and apparel export, including export quantity, markets, price and quality, this paper analyzes the export market pattern in five aspects： market space, the falling price and diminishing profit, the rising proportion of processing trade, the intense exporting competition, and the accelerating trade barriers in order to indicate the export market pattern of China＇s textiles and apparel in post-quota regime.     

Portfolio optimization with a defaultable security

In this paper we derive a closed-form solution for a representative investor who optimally allocates her wealth among the following securities: a credit-risky asset, a default-free bank account, and a stock. Although the inclusion of a credit-related financial product in the portfolio selection is more realistic, no closed-form solutions to date are given in the literature when a recovery value is considered in the event of a default. While most authors have assumed some recovery scheme in their initial model set up, they do not address the portfolio problem with a recovery when a default actually occurs. Given the tractability of the recovery of market value, we solved the optimal portfolio problem for the representative investor whose utility function is a Constant Relative Risk Aversion utility function. We find that the investor will allocate larger fraction of wealth to the defaultable security as long as the default-event risk is priced. These results are very intuitive and reasonable since it indicates that if the default risk premium is not priced properly the investor purchases less defaultable securities.     

“国有股减持”陷入困境后的反思

2001年6月，国有股减持暂行办法公布。2002年6月23日，停止通过证券市场减持国有股。从实施到停止仅一年时间，却一波三折。尽管众多这家一致看好国有股减持，但结果却令人难以置信。本从其理论依据入手，全局分析其成败得失，并指出中国股票市场的未来发展方向。

苏南农民工社会保障的实证研究

苏南农民工社会保障虽略好于江苏全省情况,但仍存在不少问题。苏南民工就业劳动合同签订率低,大部分农民工未参加任何社会保险,参加医疗、养老、工伤、失业、生育和综合保险的人数比例低。苏南农民工主要就业于私营、个体和股份制企业,就业于集体、国有企业的也有一定的比例。农民工平均工作时间长,而月收入仅相当于本地居民平均收入的60-80%。其原因,除了劳动力过剩、城乡两元体系和关系网络外,主要是由于农民工受教育程度低,工会组织不健全等。
