英文摘要:
We study the stability of several no-arbitrage conditions with respect to absolutely continuous, but not necessarily equivalent, changes of measure. We first consider models based on continuous semimartingales and show that no-arbitrage conditions weaker than NA and NFLVR are always stable. Then, in the context of general semimartingale models, we show that an absolutely continuous change of measure does never introduce arbitrages of the first kind as long as the change of measure density process can reach zero only continuously.

中文摘要:
我们研究了几个无套利条件相对于绝对连续但不一定等价的测度变化的稳定性。我们首先考虑了基于连续半鞅的模型,并证明了弱于NA和NFLVR的无套利条件总是稳定的。然后,在一般半鞅模型的背景下,我们证明了测度的绝对连续变化不会引入第一类套利,只要测度密度的变化过程只能连续地达到零。
