英文摘要:
The research presented in this work is motivated by recent papers by Brigo et al. (2011), Burgard and Kjaer (2009), Cr\\\'epey (2012), Fujii and Takahashi (2010), Piterbarg (2010) and Pallavicini et al. (2012). Our goal is to provide a sound theoretical underpinning for some results presented in these papers by developing a unified framework for the non-linear approach to hedging and pricing of OTC financial contracts. We introduce a systematic approach to valuation and hedging in nonlinear markets, that is, in markets where cash flows of the financial contracts may depend on the hedging strategies. Our systematic approach allows to identify primary sources of and quantify various adjustment to valuation and hedging, primarily the funding and liquidity adjustment and credit risk adjustment. We propose a way to define no-arbitrage in such nonlinear markets, and we provide conditions that imply absence of arbitrage in some specific market trading models. Accordingly, we formulate a concept of no-arbitrage price, and we provide relevant (non-linear) BSDE that produces the no-arbitrage price in case when the contract\'s cash flows can be replicated.

中文摘要:
本研究的动机是Brigo等人(2011年)、Burgard和Kjaer(2009年)、Crêepey(2012年)、Fujii和Takahashi(2010年)、Piterberg(2010年)和Pallavicini等人(2012年)最近发表的论文。我们的目标是通过为场外交易金融合同的套期保值和定价的非线性方法开发一个统一的框架,为这些论文中提出的一些结果提供良好的理论基础。我们在非线性市场中引入了一种系统的估值和套期保值方法,即在金融合同的现金流可能依赖于套期保值策略的市场中。我们的系统方法允许识别估值和对冲的主要来源并量化各种调整,主要是融资和流动性调整以及信用风险调整。我们提出了一种在这种非线性市场中定义无套利的方法,并给出了在某些特定市场交易模型中不存在套利的条件。因此,我们提出了无套利价格的概念,并提供了相关的(非线性)BSDE,以在合同的现金流可以复制的情况下产生无套利价格。
