Faced with the problem of pricing complex contingent claims, investors seek to make their valuations robust to model uncertainty. We construct a notion of a model-uncertainty-induced utility function and show that model uncertainty increases investors’ effective risk aversion. Using this...

Faced with the problem of pricing complex contingent claims, an investor seeks to make his valuations robust to model uncertainty. We construct a notion of a model- uncertainty-induced utility function and show that model uncertainty increases the investor's effective risk aversion. Using the...

The eight years from 2000 to 2008 saw a rapid growth in the use of securitization by UK banks. We aim to identify the reasons that contributed to this rapid growth. The time period (2000 to 2010) covered by our study is noteworthy as it covers the pre- financial crisis credit-boom, the peak of...

We study the asymmetric and dynamic dependence between financial assets and demonstrate, from the perspective of risk management, the economic significance of dynamic copula models. First, we construct stock and currency portfolios sorted on different characteristics (ex ante beta, coskewness,...

This paper examines both the in-sample and out-of-sample performance of three monetary fundamental models of exchange rates and compares their out-of-sample performance to that of a simple Random Walk model. Using a data-set consisting of five currencies at monthly frequency over the period...

This paper develops a new reduced form two-factor model for commodity spot prices and futures valuation. This models extends Schwartz's (1997) two-factor model by adding two new features. First we replace the Ornstein-Uhlenbeck process for the convenience yield by a Cox-Ingersoll-Ross (CIR)...

Motivated by the implied stochastic volatility literature (Britten-Jones and Neuberger (1998), Derman and Kani (1997), Ledoit and Santa-Clara (1998)) this paper proposes a new and general method for constructing smile-consistent stochastic volatility models. The method is developed by...
