英文摘要:
We derive integral tests for the existence and absence of arbitrage in a financial market with one risky asset which is either modeled as stochastic exponential of an Ito process or a positive diffusion with Markov switching. In particular, we derive conditions for the existence of the minimal martingale measure. We also show that for Markov switching models the minimal martingale measure preserves the independence of the noise and we study how the minimal martingale measure can be modified to change the structure of the switching mechanism. Our main mathematical tools are new criteria for the martingale and strict local martingale property of certain stochastic exponentials.

中文摘要:
我们推导了一个金融市场中存在和不存在套利的积分检验,该金融市场的风险资产要么被建模为Ito过程的随机指数,要么被建模为带有马尔可夫切换的正扩散。特别地,我们得到了最小鞅测度存在的条件。我们还证明了对于马尔可夫切换模型,最小鞅测度保持了噪声的独立性,并研究了如何修改最小鞅测度来改变切换机制的结构。我们的主要数学工具是鞅的新准则和某些随机指数的严格局部鞅性质。
