针对出口企业汇率风险管理问题,考虑购买期权预算约束,建立汇率期权套期保值模型。借助Copula函数推导出套期保值组合的分布函数,建立最小化CVaR的期权套期保值模型。利用等价转换法对模型进一步转化,并给出了模型的算法步骤。最后,以中国铂金出口企业汇率期权套期保值问题进行实证分析。实证结果表明:企业利用汇率期权套期保值可以降低CVaR风险;最优敲定价格不受出口企业风险规避度的影响;企业风险规避度越大,利用汇率期权套期保值其CVaR风险越小。期权最优敲定价格随着预算的增加而增加,但在预算一定的条件下,企业不能盲目购买敲定价格高的看跌期权,建议购买敲定价格略小于汇率当前值的期权进...

In view of the exchange rate risk management issues in export enterprises, and considering the budget constraint on purchasing options, a hedging model of exchange rate options was proposed. First, the Copula function was used to derive the distribution function of the hedged portfolio. Then, the hedging model of options with the objective of minimizing CVaR(conditional value-at-risk) was established. Besides, the model was further transformed by using the equivalence transformation method, and the algorithm steps of the model were presented. Finally, an empirical analysis was conducted by tak...
