Asymptotic arbitrage in non-complete large financial markets

Abstract: Asymptotic arbitrage in non-complete large financial markets ASYMPTOTIC ARBITRAGE IN NON-COMPLETE LARGE FINANCIAL MARKETSЮ. M. Кабанов и Д. О. Крамков ввели понятие «больших финансовых рын ков». Вместо того, чтобы рассматривать -как это обычно делается в финан совой математике -некоторый случайный процесс S цен акций, заданный на фильтрованном вероятностном пространстве (Q,!F, (^) Show more

“…We give characterizations of asymptotic arbitrage of the first and second kind and of strong asymptotic arbitrage for large financial markets with small proportional transaction costs λn on market n in terms of contiguity properties of sequences of equivalent probability measures induced by λn-consistent price systems. These results are analogous to the frictionless case, compare [16], [23]. Our setting is simple, each market n contains two assets with continuous price processes.…”

“…If, in addition, the small markets are complete, then the absence of AA is related to some contiguity properties of the sequence of equivalent martingale measures (see [12]). These results are extended to incomplete markets by Klein and Schachermayer [15,16] and by Kabanov and Kramkov [13]. When frictions are introduced, the standard assumption is that each small market is free of arbitrage under arbitrarily small transaction costs.…”

“…However, there is still the possibility of various approximations of an arbitrage profit by trading on the sequence of small markets, compare for example [9], [10], [13], [14]. The present note is focused on the condition no asymptotic free lunch (NAFL) which is the large financial market analogue of NFL, see [11].…”

“…These results can be understood as one-sided versions of the FTAP for large financial markets as contiguity corresponds to the property of absolute continuity of measures in the classical model. Criteria for the general situation (where M n is not a singleton) look more involved, see [13], [14] and in a different formulation [10]. E.g., in [10] it was shown that the above contiguity conditions can be replaced by (P n ) (Q n ) and (Q n ) (P n ), whereQ n (A) = sup Q∈M n Q(A), Q n (A) = inf Q∈M n Q(A).…”
