美国财险公司衍生工具应用的价值和业绩效应 总被引:1,自引:0,他引:1
衍生金融工具价格并非标的金融资产价格的一元线性函数,因而使用衍生工具最终是否能够起到风险管理之目的虽倾向于正面但尚存争论。本文以美国财险上市公司为研究对象,研究衍生品使用对财险公司价值和业绩的直接效应。运用Panel data模型实证检验的结果表明,衍生工具运用之于财险公司价值及业绩影响性质不同。本文提出了中国衍生产品市场推出之后放开财脸企业的投资准入的建议。 相似文献

基于中国上市公司2007~2013年财务数据,研究公司治理对管理者使用衍生金融工具的影响,并结合中国制度背景,深入分析和检验企业产权、政策监管对公司治理效应的影响。实证结果表明,公司治理对管理者使用衍生金融工具的动机存在重要影响,公司治理水平越高,管理者越倾向于利用衍生金融工具避免财务困境风险;相反,管理者越倾向于利用衍生金融工具规避薪酬风险。研究还发现,公司治理的作用机制会受到所有权性质的影响,国有控制属性会弱化公司治理效应,对衍生金融工具交易的政策监管差异是重要原因。 相似文献

金融衍生产品风险防范与公司治理 总被引:1,自引:0,他引:1
我国金融衍生产品发展比较缓慢,这与我们对金融衍生产品风险的认识有着很大关系。习惯上大家认为,金融衍生产品蕴含着大量风险.因此对开展金融衍生产品交易慎之又慎。其实,金融衍生产品交易产生的风险通常不是由产品本身所具有的风险导致的.而是由参加交易的机构错误的市场交易行为造成的,其深层的原因是这些机构往往具有不合理的公司治理机制。 相似文献

本文选择2010年沪深300指数2009年和2010年度报告为依据,首先采用logistic单因素和多因素回归的方法,检验与衍生金融工具使用相关的因素,进而采用线性回归方法,检验公司价值与衍生金融工具的使用是否相关.结果发现:公司规模与衍生金融工具的使用显著正相关,但是衍生金融工具的使用与Tobm' s Q的相关性并不显著.因此,我国企业使用衍生工具的动机,既不支持公司价值最大化理论也不支持经理层自利理论. 相似文献

信用衍生产品与现代商业银行信用风险管理 总被引:1,自引:0,他引:1
信用衍生产品作为金融市场分散和转移信贷风险的创新工具,近年来在国际金融市场获得了快速发展和成功实践,但信用衍生产品在大大提升银行风险管理水平的同时也带来了新的风险.因此,本文分析比较了现代商业银行风险管理方法,在论述信用衍生产品发展与信用风险管理互动效应的基础上,探讨了我国商业银行风险管理存在的问题与原因,并提出了相应的政策建议. 相似文献

准确可靠的定价能力不仅是银行增加资金业务收益、提高风险管理水平的重要前提,而且也是增强银行核心竞争力的技术保障。结构性衍生产品的定价过程通常由三部分构成:一是准确理解和描述产品的结构,二是选择适当的定价模型、市场数据和校准方法,三是选择最优的数值算法,定价过程最终都借助计算机程序来实现。定价的本质就是准确度量风险的价值,实现风险的对冲。最好的风险管理技术应该采用动态 Delta、Vega、Gamma 对冲。中国银行业在结构性衍生产品交易领域起步较晚,先引进外部定价软件,在此基础上逐步自主开发是实现定价能力和风险管理的现实选择。 相似文献

论文选取有色金属矿产行业以及能源交通运输行业229家上市公司作为样本,以上市公司是否使用衍生产品为解释变量,同时引用一系列控制变量,通过实证分析上市公司使用衍生产品是否会有效降低公司风险。实证过程涉及参数检验、非参数检验、相关性分析和回归分析,实证结果显示我国上市公司使用衍生产品会降低公司风险,这与西方主流的财务管理理论相一致而与我国学者以前的研究相反,由此推测我国上市公司运用衍生产品的能力逐渐娴熟。 相似文献

We examine the relationship between equity risk and the use of financial derivatives with a sample of 555 banks from eighteen developed markets from 2006 to 2015. Our main findings suggest that banks’ use of financial derivatives increased their risk. This increase in risk can be driven by banks’ use of derivatives for speculative purposes, by suboptimal hedging to obtain hedge accounting status, or from accounting mismatches that generate volatility in earnings. We also show that this relationship is nonlinear. Too-Big-To-Fail banks and those that employ a traditional retail banking business model are subject to lower idiosyncratic risk. We address endogeneity concerns using instrumental variables capturing the use of derivatives with portfolio ranking. Overall, our study contributes to understanding the impact of derivatives use on bank risk and the risk consequences of a bank’s business model choice. 相似文献

Derivatives Usage and Financial Risk Management in Large and Small Economies: A Comparative Analysis
Andrew K. Prevost Lawrence C. Rose & Gary Miller 《Journal of Business Finance & Accounting》2000,27(5&6):733-759
The objective of this paper is to expand and update previous New Zealand — based surveys in order to compare and contrast risk management practices of firms in the small, foreign trade-dependent economy of New Zealand to those of firms in the considerably larger, more developed US, UK, and German markets. This survey examines patterns of usage, reasons and objectives for derivatives use, and reporting and control procedures and finds that the practice of hedging with derivative instruments among New Zealand firms appears to be evolving as global markets become more integrated. We find that the percentage of firms involved in hedging, both large and small, has grown since the last New Zealand surveys, and that New Zealand firms have many of the same reasons and objectives for using derivatives as firms in the much larger American and European economies. We also find that the focus on control and reporting derivatives transactions in New Zealand is similar to that of firms in the other countries and appears to have strengthened since previous surveys. 相似文献

This study examines whether corporate reputation affects derivative hedging. We posit that high-reputation firms are more likely to engage in hedging due to greater reputation costs and/or their commitment to lower financial risks. We find that high-reputation firms are more likely to engage in hedging, especially when their hedging efforts or effects are more observable to stakeholders. We also find that high-reputation firms are less likely to disclose the notional values of hedging positions and that interest rate hedging by high-reputation firms is detrimental to firm value. Our results shed light on the impact of reputational concerns on corporate risk management and disclosure policies. 相似文献

This paper attempts to differentiate among the theories of hedging by using disclosures in the annual reports of 400 UK companies and data collected via a survey. I find, unlike many previous US studies, strong evidence linking the decision to hedge and the expected costs of financial distress. The tests show that this is mainly because my definition of hedging includes all hedgers and not just derivative users. However, when the tests employ the same hedging definition as previous US studies, financial distress cost factors still appear to be more important for this sample than samples of US firms. Therefore, a secondary explanation for the strong financial distress results might be due to differences in the bankruptcy codes in the two countries, which result in higher expected costs of financial distress for UK firms. The paper also examines the determinants of the choice of hedging method distinguishing between non‐derivative and derivatives hedging. My evidence shows that larger firms, firms with more cash, firms with a greater probability of financial distress, firms with exports or imports and firms with more short‐term debt are more likely to hedge with derivatives. Thus, differences in opportunities, in incentives for reducing risk and in the types of financial price exposure play an important role in how firms hedge their risks. 相似文献

金融危机中美国金融机构遭受重创的自身原因是,公司治理失效及过度的激励机制,缺乏严格的内部风险管理机制,规模快速扩张带来整合和管理的巨大难题。同时,美国计划改革其金融监管体制,发布了《现代化金融监管体制蓝图》和《金融改革框架》。欧美金融机构的转型,尤其是花旗分拆不意味着综合经营模式的失败;基于金融深化发展和适应全球金融竞争的考虑,我国商业银行应当坚持综合经营和金融创新,金融监管的变革方向应是对金融创新带来的风险实施更加有效的监管。 相似文献

The paper evaluates the effect of corporate risk management activities on firm value, using a sample of large UK non-financial firms. Following recent changes in financial reporting standards, we are able to collect detailed information on risk management activities from audited financial reports. This enables us to gain a better understanding of risk management practices and to investigate value implications of different types of hedging. Overall 86.88% of the firms in the sample use derivatives to manage at least one type of price risk. The hedging premium is statistically and economically significant for foreign currency derivative users, while we provide weak evidence that interest rate hedging increases firm value. The extent of hedging and the hedging horizon have an impact on the hedging premium, whereas operational risk management activities do not significantly influence the market value of the firm. 相似文献

Many interest rates are as volatile as exchange rates and thus represent an equallyimportant source of risk for corporations. While this is true not only for financialinstitutions, but for other corporations as well, little is known about the interest rateexposure of nonfinancial firms. Consequently, this paper investigates the impact ofinterest rate risk on a large sample of nonfinancial corporations. It presents empiricalevidence for the existence of linear and nonlinear exposures with regard to movementsin various interest rate variables. The interest rate exposure is empirically determinedby measures of firm liquidity, but not by financial leverage. 相似文献
