Abstract:
We provide an equivalent characterization of the absence of arbitrage
opportunity for the bid and ask financial market model. This result, which
is an analogue of the Dalang–Morton–Willinger theorem formulated for
discrete-time financial market models without friction, supplements and
improves the Grigoriev theorem for conic models in the two-dimensional
case by showing that the set of all terminal liquidation values is closed.
Keywords:
proportional transaction costs, absence of arbitrage opportunities, liquidation value, bid and ask prices, consistent price systems.
