  • Empirical assessment and model selection in option pricing 
    Orbay, Berk. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2016., 2016.)
    The majority of empirical option pricing studies consider the distance from the market option prices as the performance metric. Though, this kind of assessment is limited to the objectives of proper hedging of options and ...
