The developments of financial theory in the last decades have shown that one of the most fundamental topics in Finance is the specification of dependence between different risk variables. Empirical evidence on financial time series (such as returns, interest rates, or exchange rates) as well as recent developments in risk management (such as the analysis of dependence between default risks of...

This thesis focuses on two themes: a methodological and a decision making one. The methodological part introduces the development of a computerized information search tool. The program, called WebDiP (Web Decision Processes), enables the researcher to track participants while they are searching for information in a database. An experiment can be done either in the laboratory or on the Web. The...

Prenant appui sur un large corpus d'articles de presse, de discours politiques, d'enquêtes historiques et de témoignages, cette thèse étudie l'émergence, le développement et le dénouement de la controverse dite «des fonds juifs et de l'or nazi» qui a animé l'espace public suisse entre 1995 et 1998. L'enquête commence par retracer comment, plus de cinquante ans après les faits, le...

In the first part of this work we address the problem of parameter misspecification in a generic class of stochastic volatility models. We extend the approach proposed by Avellaneda, Levy and Paràs (1995) (hereafter ALP) by moving from a framework with uncertain volatility to the uncertainty on volatility process parameters. We assume that parameter values of the stochastic volatility model are...

The factors influencing the production and deposition of carbonate sediments are known. These are namely accommodation variations (eustasy and tectonics), siliciclastic sediment input, environmental changes (temperature, salinity, trophic level), nature of the producing ecologies, and the hydrodynamic regime. However, the manner in which these factors integrate through time to produce the...

Die Jura Molasse ist im distalen Tei des Molasse Beckens, einem klassischen Vorland-Becken, erhalten und überdeckte wärend des Oligo-Miozäns wahrscheinlich ein Grossteil der Jurakette. Heute findet man sie nur noch sporadisch in Talmulden oder als Karstfüllungen erhalten. Die Litho- und Biostratigraphie aller neogenen Jura-Ablagerungen sind Gegenstand einer Revision und einer Synthese. Jede...

The winter ascending circulation of air throughout an accumulation of coarse slope sediments (the so-called chimney effect) facilitates the cooling of the ground and even the occurrence of permafrost in the lower part of a deposit. Simultaneously, any freezing is unlikely to occur in the upper part. The chimney effect has been reported to date mainly for cold and sometimes perennially frozen...
