We study a notion of good-deal hedging, that corresponds to good-deal valuation and is described by a uniform supermartingale property for the tracking errors of hedging strategies. For generalized good-deal constraints, defined in terms of correspondences for the Girsanov kernels of pricing...

Today's asset management academia and practice is dominated by mean-variance thinking. In consequence, this leads to the quantification of the dependence structure of asset returns by the covariance or the Pearson's correlation coefficient matrix. However, the respective dependence measures are...

arbitrage for super and sub-hedging strategies are presented such that the super and sub-hedging prices are reasonable …. Especially the condition of arbitrage for sub-hedging strategy fills the gap of the theory of arbitrage under model uncertainty …

Traditional risk measures such as standard deviation and CVaR are properties of the distribution of returns over a specified investment horizon. Because such fixed holding period analysis is relatively easy, and because derivative contracts are fixed-term products, the analysis of derivative...

I investigate a dynamic life-cycle strategic asset allocation and consumption problem under model uncertainty, where both inflation rate and income growth rate are assumed to be estimated with errors. I present a feasible boundary for the uncertainty aversion parameter, which measures the...

We consider an investor who faces parameter uncertainty in a continuous-time financial market. We model the investor's preference by a power utility function leading to constant relative risk aversion. We show that the loss in expected utility is large when using a simple plug-in strategy for...

This paper studies the relationship between mutual fund manager investment horizons and managerial risk-taking decisions. I find that in general mutual funds reporting longer maximum evaluation horizons have lower risk levels. The low risk levels helped these funds mitigate their losses in the...

Optimization of international securitized real estate portfolios has been a key topic for several decades. However, most previous analysis has focused on regional diversification by applying the traditional mean-variance (MV) framework suggested by Markowitz (1952) even if the limitations of...
