Different weather events play an important role for industries with profits depending on temperature or other weather conditions. A market for trading on temperature events has recently emerged. The traded financial contracts allowing to transfer weather risks are called weather derivatives. The...

It is commonly known that wholesale spot electricity markets exhibit high price volatility, strong mean-reversion and frequent extreme price spikes. This paper employs a basic stochastic model, a mean-reverting model and a regime-switching model to capture these features in the Australian...

En este trabajo se analiza la dinámica de propagación de las perturbaciones de los ciclos económicos regionales en Europa y se identifican sus principales factores subyacentes. Asimismo, se propone un nuevo método para medir la sincronización variable en el tiempo en muestras pequeñas, que...

Se propone una nueva medida de la inflación subyacente que informa, en tiempo real, sobre los riesgos asimétricos en las previsiones de inflación. Las asimetrías son generadas por no linealidades inducidas por la actividad económica. El nuevo indicador se basa en un modelo multivariante de...

ENGLISH ABSTRACT: In this thesis, we propose to use Levy processes to model the dynamics of asset prices. Inthe first part, we deal with single asset options and model the log stock prices with a Levyprocess. We employ pure jump Levy processes of infinite activity, in particular variancegamma...

The paper ”Exotic Option Pricing in Stochastic Volatility Levy Models and with Fractional Brownian Motion” aims on extending the restrictive Black-Scholes model by allowing volatility to evolve randomly. These models are used to price exotic derivatives and certificates. The first stochastic...
