摘要本文研究了摩擦市场无套利的特征问题。首先,总结了(B,S)市场是无套利的充要条件:1)存在等价概率测度;2)存在最优消费策略;3)存在正的状态价格向量。
其次,基于以上三个关于摩擦市场的无套利等价性结论,结合现有金融学中衍生证券定价的研究成果,本文得出如下的结论:产品的可定价性意味着此类市场是无套利的。
最后,基于经典的Black-Scholes模型以及Harnack不等式等相关模型证实了这一结论。67262
作为对套利理论的进一步完善,本文简要分析了渐近套利问题。

Title The Analysis And Application Of Asymptotic Arbitrage
Abstract
This paper studies the characteristics problem of no-arbitrage in friction market.
Firstly,the article summed up the necessary and sufficient conditions of no-arbitrage in (B,S) market :1)the existence of equivalent probability measure;2)the existence of optimal consumption policy; 3)the existence of positive state price vector.
Secondly,based on the above equivalent conclusions about no-arbitrage in friction market and combined with the research on derivative securities pricing in the existing finance,this article drew a new conclusion: product pricing implies that such markets can exist no arbitrage opportunities.
Finally, we validated the conlusion based on related models such as the classic Black-Scholes model and Harnack inequality.
As a further improvement of arbitrage theory , this paper analyzed briefly the problem of asymptotic arbitrage.
Keywords no arbitrage, equivalent probability measure, optimal consumption, state prices, B-S model, Harnack inequality, asymptotic arbitrage
