No-arbitrage of second kind in countable markets with proportional transaction costs
نویسندگان
چکیده
Motivated by applications to bond markets, we propose a multivariate framework for discrete time financial markets with proportional transaction costs and a countable infinite number of tradable assets. We show that the no-arbitrage of second kind property (NA2 in short), introduced by [17] for finite dimensional markets, allows to provide a closure property for the set of attainable claims in a very natural way, under a suitable efficient friction condition. We also extend to this context the equivalence between NA2 and the existence of multiple (strictly) consistent price systems.

Consistent price systems and arbitrage opportunities of the second kind in models with transaction costs
In contrast with the classical models of frictionless financial markets, market models with proportional transaction costs, even satisfying usual no-arbitrage properties, may admit arbitrage opportunities of the second kind. This means that there are self-financing portfolios with initial endowments laying outside the solvency region but ending inside. Such a phenomenon was discovered by M. Rás...
متن کاملConsistent price systems under model uncertainty
We develop a version of the fundamental theorem of asset pricing for discrete-time markets with proportional transaction costs and model uncertainty. A robust notion of no-arbitrage of the second kind is defined and shown to be equivalent to the existence of a collection of strictly consistent price systems.
متن کاملNo-arbitrage in Discrete-time Markets with Proportional Transaction Costs and General Information structure
We discuss the no-arbitrage conditions in a general framework for discretetime models of financial markets with proportional transaction costs and general information structure. We extend the results of Kabanov and al. (2002), Kabanov and al. (2003) and Schachermayer (2004) to the case where bid-ask spreads are not known with certainty. In the “no-friction” case, we retrieve the result of Kaban...
متن کاملArbitrage-Free Models in Markets with Transaction Costs
In the paper [7], Guasoni studies financial markets which are subject to proportional transaction costs. The standard martingale framework of stochastic finance is not applicable in these markets, since the transaction costs force trading strategies to have bounded variation, while continuoustime martingale strategies have infinite transaction cost. The main question that arises out of [7] is w...
متن کاملComputation of arbitrage in frictional bond markets
In this paper we study the computational problem of arbitrage in a frictional market with a finite number of bonds and finite and discrete times to maturity. Types of frictions under consideration include fixed and proportional transaction costs, bid–ask spreads, taxes, and upper bounds on the number of units for transaction. We develop a necessary and sufficient condition for the existence of ...
