离散时间多先验无套利问题

No-arbitrage with multiple-priors in discrete time

Romain Blanchard, Laurence Carassus

摘要:

在离散时间和多重先验的背景下,我们提出了一个新的准确定无套利条件的特征,这已经成为一个标准的假设。这一特征表明,它确实是一个精心选择的条件,相当于几个以前使用的替代概念的无套利,并允许证明的重要成果,在金融数学。我们还重新审视了所谓的几何和定量的无套利条件和明确的两个重要的例子,所有这些概念都说明。

英文摘要:

In a discrete time and multiple-priors setting, we propose a new characterisation of the condition of quasi-sure no-arbitrage which has become a standard assumption. This characterisation shows that it is indeed a well-chosen condition being equivalent to several previously used alternative notions of no-arbitrage and allowing the proof of important results in mathematical finance. We also revisit the so-called geometric and quantitative no-arbitrage conditions and explicit two important examples where all these concepts are illustrated.
