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...

New perspectives of urban marketing suggest to build network strategies to improve cities attractiveness. Isolated quantitative researches cannot represent the multidimensional urban value. So this research, applied to the case of the Lugano area, use a basic qualitative factor of the urban value: stakeholders perception analysis in order to evaluate strengths and weakness, opportunities and...

Ranging between humanities and technological studies, this dissertation aims at clarifying what happens when literary texts we are used to read in a “book form” are transposed in hypertexts and hypermedia, namely which are the effects of this transposition on the act of reading the literary text. The work is based on an interdisciplinary approach, comprising a semiotic-hermeneutic perspective...

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...

In the first part of the thesis, we study the local robustness of inference procedures of the conditional location and scale parameters in a stationary time series model. We first derive optimal bounded-influence estimators for the parameters of conditional location and scale models under a conditionally Gaussian reference model. Based on these results, optimal bounded-influence versions of the...
