This paper proposes a robust approach to hedging and pricing in the presence of market imperfections such as market incompleteness and frictions. The generality of this framework allows us to conduct an in-depth theoretical analysis of hedging strategies for a wide family of risk measures and...

In this paper we develop the first estimator of the covariance matrix that relies solely on forward-looking information. This estimator only uses price information from a cross-section of plain-vanilla options. In an out-of-sample study for US blue-chip stocks we show that a minimum-variance...

An investor with constant absolute risk aversion trades a risky asset with general Itôdynamics, in the presence of small proportional transaction costs. In this setting, we formally derive a leading-order optimal trading policy and the associated welfare, expressed in terms of the local...

Die Stabilität der Europäischen Währungsunion ist durch die derzeit angespannte Haushaltslage und den hohen Verschuldungsgrad einiger Mitgliedstaaten in Frage gestellt. Diese Arbeit untersucht die Auswirkungen verschiedener (Krisen-)Szenarien auf das Portfolio eines durchschnittlichen...

Portfolio choice and the implied asset pricing are usually derived assumingmaximization of expected utility. In this Paper, they are derived from risk-value models that generalize the Markowitz-model. We use a behaviourally-based risk measure with an endogenous or exogenous benchmark...

We develop a new family of estimators of the covariance matrix that relies solely on forwardlooking information. It uses only current prices of plain-vanilla options. In an out-of-sample study we show that a minimum-variance strategy based on these fully-implied estimators outperforms several...

This paper provides implied measures of higher-order dependencies between assets. The measures exploit only forward-looking information from the options market and can be used to construct an implied estimator of the covariance, co-skewness, and co-kurtosis matrices of asset returns. We...

Issuers of structured products have great power when setting the price of their securities. Each issuer is the sole liquidity provider in the secondary market for her products, and short-selling is not possible. Using a large, high-frequency data set, we investigate the pricing dynamics of a...

Purpose – The purpose of this paper is to use the local correlation technique to measure flight to quality, which is defined as a pronounced and generally rapid increase in risk aversion. Flight to quality between American, British, German, Japanese, and Hong Kong spot equity indices and index...

The chapter investigates the potential application of value-at-risk metrics to risk-adjusted performance measures in the case of structured portfolios. The main issue is the appraisal of a decision criterion for portfolio choices with reference to either the asset portfolio given a structured...
