Abstract:
In securities markets, the characterisation of the absence of arbitrage by the existence of state price deflators is generally obtained through the use of the Kreps-Yan theorem. This paper deals with the validity of this theorem in a general framework. We apply this results to the characterization of the no-arbitrage assumption in a general intertemporal framework.
