    Sammanfattning : Asset pricing modeling is a wide range area of research in Financial Engineering. In this thesis, which consists of an introduction, three papers and appendices; we deal with asset pricing models with stochastic volatility. Here stochastic volatility modeling includes diffusion models and regime-switching models. LÄS MER

  5. 4. Analytical Approximation of Contingent Claims

    Författare :Karl Larsson; Claus Munk; Nationalekonomiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Option pricing; approximation; stochastic volatility; implied volatility; perturbation; Malliavin calculus; commodities; swaption; swap; HJM model;

    Sammanfattning : This PhD thesis consists of three separate papers. The common theme is methods to calculate analytical approximations for prices of different contingent claims under various model assumptions. The first two papers deals with approximations of standard European options in stochastic volatility models. LÄS MER

  7. 5. VAR Models, Cointegration and Mixed-Frequency Data

    Författare :Sebastian Ankargren; Johan Lyhagen; Yukai Yang; Gregor Kastner; Uppsala universitet; []
