在下游零售商同时面临市场需求风险和汇率风险的背景下,研究了汇率风险对冲(外汇期货对冲)策略在全球供应链运作及风险管理中的作用。在无/有对冲策略两种情形下分别构建了上游制造商和下游零售商的动态博弈模型,并求解了均衡结果。两种情形下的均衡结果显示,汇率风险对冲策略可以提高供应链系统订货量、增加零售商收益的期望值和确定性等价量、增加供应链系统的总收益。进一步讨论了有对冲策略的情形下,两类外生风险对供应链均衡决策变量和盈利性的影响方式。结果表明,汇率风险对冲策略对汇率风险起到了有效的隔离作用,避免了供应链下游的汇率风险向上游企业传递,并能实现供应链收益与风险的权衡。 相似文献

为研究人民币利率互换市场中流动性风险和违约风险的市场价格,运用三因子广义高斯仿射模型,同时对人民币国债市场利率、银行间质押式回购市场利率和利率互换市场利率进行模拟,并采用极大似然估计方法估计众多参数。结果发现,在目前的人民币利率互换定价过程中,流动性要素相对违约要素更加重要,市场给予流动性风险以显著的风险溢价。如采用互换利差定价法为人民币利率互换定价的话,可以以回购利率作为基准,在此基础上考虑信用风险来进行。 相似文献

在均值-方差准则下研究具有利率风险和通胀风险的资产负债管理问题.首先,利用Lagrange乘子技术将这个资产负债管理问题转化为一个标准的均值-方差有效问题.然后,利用Hamilton-Jacobi-Bellman方法、偏微分方程方法和Lagrange对偶定理得到原问题有效的投资策略和有效前沿的解析表达式.最后,在解析表达式的基础上,通过数值算例分析了模型主要参数对投资策略和有效前沿的影响. 相似文献

In this paper we formulate a model for foreign exchange exposure management and (international) cash management taking into consideration random fluctuations of exchange rates. A vector error correction model (VECM) is used to predict the random behaviour of the forward as well as spot rates connecting dollar and sterling. A two-stage stochastic programming (TWOSP) decision model is formulated using these random parameter values. This model computes currency hedging strategies, which provide rolling decisions of how much forward contracts should be bought and how much should be liquidated.The model decisions are investigated through ex post simulation and backtesting in which value at risk (VaR) for alternative decisions are computed. The investigation (a) shows that there is a considerable improvement to “spot only” strategy, (b) provides insight into how these decisions are made and (c) also validates the performance of this model. 相似文献

??It is assumed that both an insurance company and a reinsurance company adopt the variance premium principle to collect premiums. Specifically, an insurance company is allowed to investment not only in a domestic risk-free asset and a risky asset, but also in a foreign risky asset. Firstly, we use a geometry Brownian motion to model the exchange rate risk, and assume that the insurance company could control the insurance risk by transferring the insurance business
into the reinsurance company. Secondly, the stochastic dynamic programming principle is used to study the optimal investment and reinsurance problems
in two situations. The first is a diffusion approximation risk model and the second is a classical risk model. The optimal investment and reinsurance strategies are obtained under these two situations. We also show that the exchange rate risk has a great impact on the insurance company's investment strategies, but has no effect on the reinsurance strategies. Finally, a sensitivity analysis of some parameters is provided. 相似文献

外汇储备规模与多元变量弹性系数的实证研究 总被引:5,自引:0,他引:5
中国外汇储备近几年的迅速增长引发了关于中国外汇储备规模是否适度的广泛讨论。本文从需求的角度,运用计量经济学的多元线性回归的方法,建立中国外汇储备与平均进口倾向、进口和国际收支三变量的双对数模型,通过计算并通过相关检验得到外汇储备与相关变量的弹性系数。为预测和制定相关政策提供依据。 相似文献

需求风险是企业面临的主要风险之一,对企业的生产经营和管理决策具有重要影响。本文考虑由多个风险厌恶企业构成的产品竞争市场,分析了需求风险下企业参与套期保值和市场进入的决策问题。文章首先通过Cournot博弈分析了套期保值对于规避需求风险的作用和意义;然后,探讨了企业参与套期保值和市场进入的决策过程,并给出了三种情形下的市场均衡结构;最后,通过数值实验对结论进行了验证。研究表明:套期保值提高了企业应对需求风险的能力,使企业获得更高的产量和收益;参与套期保值企业数量随着进入市场企业数量的增加而减少;当市场竞争程度或市场费用增加时,将会有更多的企业选择参与套期保值,而选择进入市场的企业会减少。 相似文献
