Monetary policy and interest rate products

Zurowski, Wojciech ; Schneider, Paul (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2019 ; 20019ECO002.

My PhD thesis consists of three papers which study how interest rate products' prices react to both the central bank's policy goals and communication. As tool I make use of various econometric techniques such as affine models, general method of moments or Haar like filtering. The first chapter studies government bond excess term premia. I show that their predictability is driven by monetary...

Chemokine heterocomplexes and cancer : A novel chapter to be written in tumor immunity

D'Agostino, Gianluca ; Cecchinato, Valentina ; Uguccioni, Mariagrazia

In: Frontiers in immunology, 2018, vol. 9, p. 2185

Infiltrating immune cells are a key component of the tumor microenvironment and play central roles in dictating tumor fate, either promoting anti-tumor immune responses, or sustaining tumor growth, angiogenesis and metastasis. A distinctive microenvironment is often associated to different tumor types, with substantial differences in prognosis. The production of a variety of chemotactic...

To split or not to split Anthracotherium? A phylogeny of Anthracotheriinae (Cetartiodactyla: Hippopotamoidea) and its palaeobiogeographical implications

Scherler, Laureline ; Lihoreau, Fabrice ; Becker, Damien

In: Zoological Journal of the Linnean Society, 2019, vol. 185, no. 2, p. 487–510

Since its first erection almost 200 years ago, palaeontologists have assigned to the genus Anthracotherium many species, some with dubious descriptions. Although it is a key taxon for specifying the invasion of Europe by terrestrial mammals during the well-studied Grande Coupure Event at the beginning of the Oligocene, the genus has never been reviewed before. A recent interest in the...

Similarities and differences in altitudinal versus latitudinal variation for morphological traits in Drosophila melanogaster

Klepsatel, Peter ; Gáliková, Martina ; Huber, Christian D. ; Flatt, Thomas

In: Evolution, 2014, vol. 68, no. 5, p. 1385–1398

Understanding how natural environments shape phenotypic variation is a major aim in evolutionary biology. Here, we have examined clinal, likely genetically based variation in morphology among 19 populations of the fruit fly (Drosophila melanogaster) from Africa and Europe, spanning a range from sea level to 3000 m altitude and including locations approximating the southern and northern range...

3D morphology of pharyngeal dentition of the genus Capoeta (Cyprinidae): Implications for taxonomy and phylogeny

Ayvazyan, Anna ; Vasilyan, Davit ; Böhme, Madelaine

In: Journal of Zoological Systematics and Evolutionary Research, 2019, vol. 57, no. 1, p. 179–190

Capoeta is a herbivorous cyprinid fish genus, widely distributed in water bodies of Western Asia. Recent species show a distinct biogeographic pattern with endemic distribution in large fluvial drainage basins. As other cyprinids, the species of this genus are characterized by the presence of the pharyngeal bone with pharyngeal teeth. Despite this, the detailed morphology of the pharyngeal...

Three essays in economics of catastrophes

Slerca, Edoardo ; Jametti, Mario (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2018 ; 2018ECO013.

Many events can have a catastrophic effect on an economic environment, such as natural disasters, wars, migrations, pandemic diseases, etc. This thesis focuses on three of them: catastrophic agglomeration of firms as a response to tax differentials, immigration phenomena described as catastrophic by the natives and catastrophic earthquakes with destructive consequences for both physical and...

Integrating anti-money laundering compliance duties into the banking culture

Sandulescu, Mihaela ; Barone Adesi, Giovanni (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2016 ; 2016ECO011.

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...

Progressively excluding mammals of different body size affects community and trait structure of ground beetles

Wang, Xiaowei ; Steiner, Magdalena ; Schütz, Martin ; Vandegehuchte, Martijn L. ; Risch, Anita C.

In: Oikos, 2018, vol. 127, no. 10, p. 1515–1525

Mammalian grazing induces changes in vegetation properties in grasslands, which can affect a wide variety of other animals including many arthropods. However, the impacts may depend on the type and body size of these mammals. Furthermore, how mammals influence functional trait syndromes of arthropod communities is not well known. We progressively excluded large (e.g. red deer, chamois),...

Derivative securities in risk management and asset pricing

Legnazzi, Chiara ; Barone-Adesi, Giovanni (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2018 ; 2018ECO009.

The high informational content and the ease of accessibility are among the most attractive features which make derivative securities particularly useful in financial applications. With a special focus on risk management and asset pricing, I present several methodologies which involve the use of option and futures data in the estimation process. This doctoral thesis consists of three chapters....
