Option pricing in the presence of natural boundaries and a quadratic diffusion term

This paper uses a probabilistic change-of-numeraire technique to compute closed-form prices of European options to exchange one asset against another when the relative price of the underlying assets follows a diffusion process with natural boundaries and a quadratic diffusion coefficient. The paper shows in particular how to interpret the option price formula in terms of exercise probabilities which are calculated under the martingale measures associated with two specific numeraire portfolios. An application to the pricing of bond options and certain interest rate derivatives illustrates the main results.

内部评级法在国内商业银行实施的本土化研究

内部评级法的实施需要建立在一定的前提基础之上,中国目前的实施条件还存在一定的缺陷,因此如何在内部评级体系的构建过程中体现本土化的原则将成为有效实施的关键。中国特有的金融生态决定了地区之间的金融风险差异较大,因此在具体实施过程中,应将地区金融风险差异作为调整系数对内部评级法的评级结果进行调整。中国的商业银行尚处于内部评级法实施的准备或开始阶段,受实施条件和金融生态的限制,本土化将是一个长期的、渐进的创新过程。本土化并不仅仅是内部评级法相关标准的本地化应用,同时也要求在这一过程中有创造性地发挥内部评级法对银行风险管理的积极作用。     

从国际经济学理论视角看企业竞争优势——兼议国际经济学优势思想的演进

本文通过回顾和分析国际经济学中国际贸易理论和国际直接投资理论优势思想的发展和]进,说明了理论研究可以通过对各种市场结构的细分,把优势分析引入到企业内部,并通过对分工、市场结构与交易费用之间的矛盾关系的深入研究,探讨内生优势与外生优势之间的对立统一关系,而企业竞争优势的培育则是一个建立在企业自身独特能力基础上的、综合利用企业内外部各种比较优势的动态累积发展过程。

The impact of tax holidays on earnings management: An empirical study of corporate reporting behavior in a developing-economy framework

This study investigates whether foreign investment enterprises (FIEs) in China alter their corporate reporting behavior in response to a known schedule of tax-rate increases. The context of this investigation is a tax-incentive scheme that allows firms to pay taxes at a reduced rate for a limited period of time, and then at a higher rate when this period expires. If managers attempt to maximize firm value by minimizing tax costs, then the spread of tax rates in the periods surrounding the rate change may provide a substantial incentive for them to accelerate revenue and defer expenses. Consistent with this hypothesis, the empirical results indicate that firms report significantly higher discretionary current accruals for the years before tax-rate increases. The evidence, which indicates that firms manage earnings upward to take advantage of lower tax rates that are available in certain years, has important implications for tax policymakers.     

英国的非公开权益资本和风险投资

英国是欧洲风险投资和非公开权益资本的发源地。在欧洲国家中,英国的风险投资和非公开权益资本起步最早,发展也最快。从1979年算起,英国风险资本投资额和非公开权益资本增长了100多倍。2005年,在欧洲的风险投资市场上,英国的风险资本总额占欧洲风险投资额的40￣50%,在欧洲是当仁不让的“大哥大”,在世界范围内仅次于美国。本篇文章主要介绍了风险投资(VentureCapital,VC)及非公开权益资本(PrivateEquity,PE)的最新概念和从属关系以及英国的风险投资及非公开权益资本的历史、结构、规模、投资趋势、投资阶段、投资领域、地理特征、知名风险企业、投资表现等,以此从数据和分析的角度使中国的风险投资领域及非公开权益资本领域的从业人员以借鉴、启迪的作用。

Sales force technology usage—reasons, barriers, and support: An exploratory investigation

Increasingly, salespeople are being asked to adopt and use a variety of technologies to increase their selling productivity and efficiency, including sales force automation and customer relationship management technologies. However, little research has investigated what happens once sales force automation (SFA) technology is adopted. This paper explores the reasons why salespeople use SFA technologies, the perceived barriers to SFA usage and how management can increase the usage of SFA technology. First, a qualitative study was performed to gain insight about salespeople's automation technology usage and the reasons why some salespeople fully use or do not utilize technology. After the initial study, 130 salespeople were surveyed. More productivity/efficiency was the main reason why salespeople use technology, the lack of management and technical support proved to be the main barrier to usage, and training proved most effective in increasing usage of SFA technology. Sales managers are provided with implications of the findings.     

The potential of integrated reporting to enhance sustainability reporting in the public sector

This paper examines the influence of integrated reporting (IR) on the sustainability reporting practices of a state-owned enterprise through a content analysis of their reports and interviews with report preparers. The findings show a steady increase in the quantity and quality of sustainability disclosures. In 2012, the organization chose to adopt the IR framework in order to enhance sustainability reporting for all stakeholders. The IR process resulted in a more balanced disclosure of material aspects of sustainability. However, while IR has the potential to enhance public sector sustainability reporting, inter-generational equity issues were ignored.
