In this paper the dynamic portfolio selection problem is studied for the first time in a dual utility theory framework. The Wang transform is used as distortion function and well diversified optimal portfolios result both with and without short sales allowed.

Structural models' main source of uncertainty is the stochastic evolution of the firm's asset value. These models are commonly used to value corporate debt at the issue and hence to determine its yield given the amortization plan. This paper proposes two discrete models to value securities...

We propose a simple model of decision making under risk inspired by the "half-full, half-empty" glass metaphor. The model is intuitive in that it is closely related to the expected value criterion and its parameters have a clear behavioral interpretation, and parsimonious in that it provides an...

The object of this paper is to investigate the role of interest rate risk measures set out in an immunization theory framework for the control of the hedge effectiveness test, as specified in IAS 39. In particular, the case of a cash flow hedge is analyzed and attention is drawn to how the use...

In recent years both practitioners and academics have realised that traditional discounted cash flow models erroneously consider the option value embedded in firms. Hence equity and debt valuation methodologies based on option theory have recently become quite popular. Such methodologies take...

This paper investigates the price for contingent claims in a dual expected utility theory framework, the dual price, considering complete arbitrage-free nancial markets. In this framework this dual price is obtained, for the rst time in the literature, without any comonotonicity hypothesis and...

This paper investigates the price for contingent claims in a dual expected utility theory framework, the dual price, considering arbitrage-free nancial markets. A pricing formula is obtained for contingent claims written on n underlying assets following general Itô processes and without any...
