中国古典谋略与战争中的心理博弈

奇正相生、虚实相合,刚柔并济、软硬兼施,因敌制变、因情措法,绵里藏针、对症下药,先胜后战、先声夺人等中国古典谋略思想,植根于中华传统文化的肥沃土壤,来源于历代丰富的战争实践,汲取了古典哲学思维、兵学思想和谋略艺术中的不朽智慧,对于战争中心理博弈能力、技巧和水平的提升具有重要的指导意义。     

我国股指期货的套期保值比率研究

本文主要运用OLS、VAR、ECM、diagonal-BEKK、full-BEKK、scalar-BEKK对沪深300股指期货仿真交易的套期保值比率进行研究,比较了静态套期模型和动态套期保值模型的效果,并研究不同参数化形式对动态套期保值模型的影响。结果表明尽管动态套期保值在样本内要优于静态套期保值模型,但样本外效果却不是很好;另外,动态模型的不同的参数化形式对结果的影响也比较大。     

双重看涨期权定价的估计

在市场无套利、无摩擦和无风险利率为常数假定下,分别讨论了无红利配发和有红利配发情形时,一种新型期权—双重看涨期权的定价问题,主要利用套期保值策略对期权定价进行了若干估计,给出了上下界.     

具有分数O-U过程的永久美式看跌期权的定价

该文研究具有分数Ornstein-Uhlenbeck过程的永久美式看跌期权的定价问题.首先, 利用分析金融衍生品定价的delta对冲方法和无套利原理, 遵循标准的讨论步骤, 建立了标的资产价格服从分数Ornstein-Uhlenbeck过程的欧式看涨期权和看跌期权的定价公式.然后, 通过求解一个自由边界问题, 对标的资产价格服从分数Ornstein-Uhlenbeck过程的永久美式看跌期权的定价以及实施该期权时的临界标的资产价格给出了显式解.     

Variance optimal hedging for continuous time additive processes and applications

For a large class of vanilla contingent claims, we establish an explicit Föllmer–Schweizer decomposition when the underlying is an exponential of an additive process. This allows to provide an efficient algorithm for solving the mean variance hedging problem. Applications to models derived from the electricity market are performed.     

Information on jump sizes and hedging

We study a hedging problem in a market where traders have various levels of information. The exclusive information available only to informed traders is modelled by a diffusion process rather than discrete arrivals of new information. The asset price follows a jump–diffusion process and an information process affects jump sizes of the asset price. We find the local risk minimization hedging strategy of informed traders. Numerical examples as well as their comparison with the Black–Scholes strategy are provided via Monte Carlo.     

Outsourcing and capacity planning in an uncertain global environment

Firms employing offshore outsourcing strategies may face both exchange rate and demand uncertainties. In this paper, we show that the firms may benefit from operational option to switch production by keeping capacities with both domestic and foreign suppliers. The value of the operational option increases as the exchange rate uncertainty or demand uncertainty increases. In addition, when the firms become risk-averse, they may use domestic capacity to hedge against offshore capacity. As a result, the firms may choose to hold local capacity even if it exhibits negative marginal contribution to the profit. Furthermore, risk-averse firms may keep more total capacity than risk-neutral firms.     

Black-Scholes期权定价的风险(英文)

Black-Scholes期权定价的推导假定对冲是连续的以达到无风险. 但事实上, 股市收市后将不再有交易, 所以投资者不能连续的调整其投资组合, 故期权定价的风险是存在的. 本文讨论了这种不连续对冲带来的期权定价的风险, 并以美国股市的几种指标股为例, 给出其比率. 比率多在5%以上, 有的可以达到38%, 可见传统期权定价的风险不容小觑.
