Specification Analysis of Affine Term Structure Models

This paper explores the structural differences and relative goodness-of-fits of affine term structure models (ATSMs). Within the family of ATSMs there is a trade-off between flexibility in modeling the conditional correlations and volatilities of the risk factors. This trade-off is formalized by our classification of N -factor affine family into N + 1 non-nested subfamilies of models. Specializing to three-factor ATSMs, our analysis suggests, based on theoretical considerations and empirical evidence, that some subfamilies of ATSMs are better suited than others to explaining historical interest rate behavior.     

Caught in the crossfire: Dimensions of vulnerability and foreign multinationals' exit from war‐afflicted countries

Research summary : When war occurs in a country, some foreign multinational enterprises (MNEs) stay on, while others flee. We argue that MNE responses to external threats depend on the firm's vulnerability, which we decompose into exposure (proximity to threat), at‐risk resources (potential for loss), and resilience (capacity for coping). We test the independent and interactive effects of these dimensions using a geo‐referenced sample of 1,162 MNE subsidiaries in 20 war‐afflicted countries between 1987 and 2006. We find that highly valuable resources can become liabilities when exposed to harm, and the best way to cope with external threats may be to exit. Our findings extend the resource‐based view and real options theory by demonstrating the bounded value of resources and options in the face of environmental contingencies. Managerial summary : A recent survey of multinational enterprise (MNE) executives revealed that 30 percent of the respondents believed that their firms were exposed to collateral damage from war, with more than 90 percent expecting risks to rise. Yet, 25 percent of the executives indicated that their firms had no continuity plan. Our study of MNEs in war‐afflicted countries highlights the costs of not having a response strategy in place. We find that, in war zones, otherwise highly valuable locations and resources can become sources of vulnerability that prompt early withdrawal from a host country. Our work further highlights the value of real options thinking—where structural solutions such as building redundancy into a portfolio of options may exist in advance of problems—for navigating hostile environments.

煤层气开发投资项目不确定性综合评估方法探讨

在评价煤层气开发项目经济效益的过程中,常采用敏感性分析来评估项目的不确定性,但敏感性分析无法综合评估项目的不确定性。本文开展此项研究以期建立简便、可操作的综合不确定性分析方法。为此,利用模拟方案生成数据,对数据进行统计分析,寻找不确定因素与效益指标之间的函数关系。研究发现,当不确定因素在一定范围内波动时,多因素变动对经济效益的综合影响可以近似为单因素影响的线性叠加,即可利用单因素敏感曲线的拟合斜率来构建综合评价公式。线性叠加会产生计算误差,误差随因素变动范围的扩大而增加,不确定因素在±25% 范围内波动时,90% 以上的数据落在误差区间为±10% 的范围之内。文中建立的方法可以对方案进行综合不确定性评价,优选方案。

我国上市公司募集资金投向变更研究

本文以 2 0 0 0年度发行股票融资的 3 2 2家上市公司为研究样本 ,首次将募股资金投向变更区分为隐性变更和显性变更 ,分析得出的主要结论是 :(1 )我国上市公司普遍且较大程度地变更募集资金投向 ;(2 )IPO公司的变更面和变更程度比配股公司和增发公司更突出 ;(3 )隐性变更比显性变更更严重 ,上市公司资金闲置问题突出 ;(4)上市公司资产规模与资金投向变更呈显著负相关 ;(5)四重约束缺失是导致上市公司变更募资投向的主要原因 ;(6)从短期看 ,变更募资投向对上市公司业绩有较明显的影响。论文最后提出了若干政策建议     

我国证券信用交易引入与股价波动相关性分析

我国拟同时推出融资交易和融券交易,但融资交易量将明显大于融券交易量。因此,证券信用交易引入初期对我国股价波动的影响首先将表现为融资交易带来的股价上涨。从长期来看,在我国,证券信用交易对股价波动存在多样化的传导机制。引入证券信用交易可以在一定程度上平抑我国的股价波动,但我国投资者出于“跟涨杀跌”行为作出的融资融券将加剧股价波动。
