Empirical indicators of sentiment are commonly employed in the economic literature while a precise understanding of what is sentiment is still missing. Exploring the links among the most popular proxies of sentiment, fear and uncertainty this paper aims to fill this gap. We show how fear and sentiment are specular in their predictive power in relation to the aggregate market and to...

We investigate the shape of risk appetite when the bank is financed also with contingent convertible bonds (CoCos). Our contribution to the existent literature is to assess risk appetite in a multi-dimensional perspective and to account for differences among banks' clusters, especially in a world with CoCos and policy rates approaching zero or negative figures. In our model, the bank objective...

This thesis sets out to investigate whether the anti-money laundering (AML) compliance duties have been integrated into the banking culture. The first two chapters briefly present the Swiss AML framework and relevant numbers. Using survey data from 52 respondents, Chapter 3 presents evidence on how banks coped with compliance requests, starting from the internal due diligence and reporting...

This thesis is made of three articles dealing with two main subjects: the so called "Kernel Puzzle" and the problem of immunization of portfolio of treasury and corporate bonds. For the first topic, we provide a new method to derive the state price density per unit probability based on option prices and GARCH model. We derive the risk neutral distribution using the result in Breeden and...

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...

By examining the gold leasing market and employing data on the gold forward offered rate (GOFO) and derived lease rates, we propose that rather than using the interest-adjusted basis as a proxy for the convenience yield of gold, the convenience yield is better approximated by the derived gold lease rate. Additionally, using the interest-adjusted basis as opposed to the lease rate can lead to...

We estimate arbitrage-free term structure models of US Treasury yields and spreads on BBB and B-rated corporate bonds in a doubly- stochastic intensity-based framework. A novel feature of our analysis is the inclusion of macroeconomic variables – indicators of real activity, inflation and financial conditions – as well as latent factors, as drivers of term structure dynamics. Our results...

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...

In this thesis I have tried to identify the risks and opportunities crude oil market offers. For this purpose I tested the performance of univariate and multivariate GARCH models. The first part of the work describes univariate GARCH models and their application to commodities markets. Physical ownership of the commodity carries an associated flow of services. The net flow of these services per...

This thesis represents the first attempt to address the issue in a comprehensive way. The first two papers explore to what degree the market disciplines Swiss banks, both directly and indirectly. The empirical results...
