连续金融市场的弱和强无套利条件

Weak and strong no-arbitrage conditions for continuous financial markets

Claudio Fontana

摘要:

对基于连续半鞅的金融市场模型的整个无套利条件谱进行了统一分析。特别是,我们专注于无套利条件弱于经典的概念,没有套利和没有免费的午餐与消失的风险。我们提供了一个完整的表征所考虑的无套利条件,其有效性的特点,贴现资产价格过程和(弱)鞅平减指数的存在性和性质,并回顾经典以及最近的结果。

英文摘要:

We propose a unified analysis of a whole spectrum of no-arbitrage conditions for financial market models based on continuous semimartingales. In particular, we focus on no-arbitrage conditions weaker than the classical notions of No Arbitrage and No Free Lunch with Vanishing Risk. We provide a complete characterisation of the considered no-arbitrage conditions, linking their validity to the characteristics of the discounted asset price process and to the existence and the properties of (weak) martingale deflators, and review classical as well as recent results.
