Rational hedging and valuation of integrated risks under constant absolute risk aversion

Rentseeking by Players with Constant Absolute Risk Aversion

We introduce a novel method of modelling Tullock rent-seeking contests that avoids the complexities encountered by the ‘best response function’ approach. We analyse contests in which there are many risk averse players differing in their attitudes to risk. We establish that, if every player has a constant degree of absolute risk aversion, a unique equilibrium exists. We also establish comparativ...

Commodity Futures Hedging, Risk Aversion and the Hedging Horizon

This paper examines the impact of management preferences on optimal futures hedging strategy and associated performance. Applying an expected utility hedging objective, the optimal futures hedge ratio is determined for a range of preferences on risk aversion, hedging horizon and expected returns. Empirical results reveal substantial hedge ratio variation across distinct management preferences a...

Catastrophe Aversion and Risk Equity under Dependent Risks

Catastrophe aversion and risk equity are important concepts in both risk management theory and practice. Keeney (1980) was the first to formally define these concepts. He demonstrated that the two concepts are always in conflict. Yet this result is based on the assumption that individual risks are independent and has thus limited relevance for real world catastrophic events. We extend Keeney’s ...

Credit Risk: Modelling, Valuation and Hedging

Rational Hedging and Valuation with Utility-Based Preferences

In this thesis, we study stochastic optimization problems in which concave functionals are maximized on spaces of stochastic integrals. Such problems arise in mathematical finance for a risk-averse investor who is faced with valuation, hedging, and optimal investment problems in incomplete financial markets. We are mainly concerned with utility-based methods for the valuation and hedging of non...
