Where prices are missing as an indicator of value, economic non-market valuation represents an important tool for efficient and transparent decision-making. Given that environmental goods and services are often priceless, environmental economists have a long history of applying valuation tools. Two prominent valuation approaches are the Contingent Valuation Method (CVM) and the Travel Cost Method...

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...

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...

L’obiettivo della tesi è di individuare le motivazioni che spingono un’azienda a comunicare mediante l’umorismo. L’umorismo viene considerato in chiave strumentale al fine di poter trarre indicazioni su dove, come e quando sia più utile optare per tale linguaggio. Dopo un’introduzione storico-filosofica (cap.2) volta a mostrare le principali correnti di pensiero che nei secoli si sono...

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...
