英文摘要:
This paper focuses on the stability of the non-arbitrage condition in discrete time market models when some unknown information $\\tau$ is partially/fully incorporated into the market. Our main conclusions are twofold. On the one hand, for a fixed market $S$, we prove that the non-arbitrage condition is preserved under a mild condition. On the other hand, we give the necessary and sufficient equivalent conditions on the unknown information $\\tau$ to ensure the validity of the non-arbitrage condition for any market. Two concrete examples are presented to illustrate the importance of these conditions, where we calculate explicitly the arbitrage opportunities when they exist.

中文摘要:
本文研究离散时间市场模型中,当一些未知信息$\\tau$部分/完全并入市场时,无套利条件的稳定性。我们的主要结论有两个。一方面,对于一个固定的市场,我们证明了无套利条件在一个温和的条件下保持不变。另一方面,我们给出了未知信息$\\tau$的等价充要条件,以保证无套利条件对任何市场的有效性。给出了两个具体的例子来说明这些条件的重要性,其中我们明确计算了存在套利机会时的套利机会。
