Title:On the Approximation of Random Variables by Stochastic Integrals with Respect to Semimartingales
Author-Name:Christopeit, Norbert
Classification-JEL:G11, G13
Keywords:stochastic integration, hedging, incomplete markets
Abstract: In this paper it is shown that the space of stochastic integrals w.r. to a special semimartingal is closed and hence
	every square integrable random variable admits a best approximation in this space. In terms of financial economics this
	means that for every contingent claim there exists a hedging strategy minimizing the expected square of net loss.
