By relying on the theory of progressive enlargement of filtrations …, we explicitly show that no kind of arbitrage profit can ever be realised strictly before τ, whereas classical arbitrage … starting to trade as soon as τ occurs. We carefully study the behavior of local martingale deflators and consider no-arbitrage …

This paper proves the fundamental theorem of asset pricing with transaction costs, when bid and ask prices follow locally bounded càdlàg (right-continuous, left-limited) processes. The robust no free lunch with vanishing risk condition (RNFLVR) for simple strategies is equivalent to the...

Under proportional transaction costs, a price process is said to have a consistent price system, if there is a semimartingale with an equivalent martingale measure that evolves within the bid-ask spread. We show that a continuous, multi-asset price process has a consistent price system, under...
