In this paper we follow a different approach by taking a first step towards an option valuation model which does not explicitly make use of unobservable State variables. Instead of using a stochastic variance variable directly, we assume that the variance of stock returns is determined by the...

In this paper we examine small sample properties of a generalized method of moments (GMM) estimation using Monte Carlo simulations. We assume that the generated time series describe the stochastic variance rate of a stock index. We use a mean reverting square-root prooess to simulate the...

Das Lehrbuch stellt die klassischen Teilgebiete der Finanzmathematik systematisch dar. Ein neues Kapitel beschreibt, welche Schwierigkeiten bei der Informationsbeschaffung zu bewältigen sind, wenn typische finanzmathematische Fragestellungen beantwortet werden müssen.
