英文摘要:
This paper completes the analysis of Choulli et al. Non-Arbitrage up to Random Horizons and after Honest Times for Semimartingale Models and contains two principal contributions. The first contribution consists in providing and analysing many practical examples of market models that admit classical arbitrages while they preserve the No Unbounded Profit with Bounded Risk (NUPBR hereafter) under random horizon and when an honest time is incorporated for particular cases of models. For these markets, we calculate explicitly the arbitrage opportunities. The second contribution lies in providing simple proofs for the stability of the No Unbounded Profit with Bounded Risk under random horizon and after honest time satisfying additional important condition for particular cases of models.

中文摘要:
本文完成了Choulli等人对半鞅模型在随机区间和诚实时间后的无套利的分析,包含两个主要贡献。第一个贡献在于提供和分析了许多市场模型的实际例子,这些模型承认经典套利,同时在随机视界下,以及在模型的特定情况下,当引入诚实时间时,它们保持有界风险的无无界利润(下文简称NUPBR)。对于这些市场,我们明确计算套利机会。第二个贡献在于,对于模型的特殊情况,在满足额外重要条件的诚实时间下,为具有有限风险的无无界利润的稳定性提供了简单的证明。
