Essays on variance risk

Gruber, Peter ; Trojani, Fabio (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2015 ; 2015ECO010.

My PhD thesis consists of three papers which study the nature, structure, dynamics and price of variance risks. As tool I make use of multivariate affine jump-diffusion models with matrix-valued state spaces. The first chapter proposes a new three-factor model for index option pricing. A core feature of the model are unspanned skewness and term structure effects, i.e., it is possible that the...

Three essays in real options

Baranouskaya, Vera ; Barone Adesi, Giovanni (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2010 ; 2010ECO005.

Real options refer to the investment, entry, exit and other strategic decisions of the firm that share three important characteristics: they are irreversible, they are made under uncertainty, and their timing is chosen by the firm. The term `real options' was introduced in 1977 by Stewart Myers in his paper `Determinants of corporate borrowing' that related risky debt holdings to the future...

Three essays in option pricing

Fusari, Nicola ; Barone Adesi, Giovanni (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2009 ; 2009ECO002.

The present work explores the option pricing world under three different perspectives: theoretical models, numerical methods and real options. In the first chapter we develop a novel option pricing model. We define a stochastic volatility process for the underlying evolution using the realized volatility as a proxy of the true but unobservable volatility of the underlying. That reduces...

An option pricing formula for the GARCH diffusion model

Ravanelli, Claudia ; Barone-Adesi, Giovanni (Dir.) ; Chesney, Marc (Codir.) ; Vanini, Paolo (Codir.)

Thèse de doctorat : Università della Svizzera italiana, 2003 ; 2003ECO001.

In this thesis, we derive an analytical closed-form approximation for European option prices under the GARCH diffusion model, where the price is driven by a geometric process and the variance by an uncorrelated mean reverting geometric process. This result has several important implications. First and foremost, these conditional moments allow us to obtain an analytical closed-form approximation...
