mini-workshop "Young Researchers" a Milano-Bicocca
by Fabio Bellini 11 Jul '14

11 Jul '14

Il giorno giovedì 17 luglio alle ore 14.30 presso la Sala del Consiglio della Scuola di Economia e Statistica, al IV piano dell'edificio U7 in via Bicocca degli Arcimboldi 8, si terrà il mini-workshop "Young Researchers" con il seguente programma: 14.30 - 15.00 Annamaria Gambaro, Dottorato in Statistica e Matematica per la Finanza, Curriculum Matematica per la Finanza, Università di Milano-Bicocca Approximated pricing of swaptions in general interest rate models We propose a new lower bound on the prices of European-style swaptions for a wide class of interest rate models. This method is applicable whenever the joint characteristic function of the state variables is known in closed form or could be easily obtained with numerical PDE solution method. Our algorithm involves the computation of one dimensional Fourier transform indipendently from the swap length. Moreover the bound could be used as a control variable to reduce confidence interval of the Monte Carlo technique. We test our new lower bound on different affine models and on 2-factor quadratic gaussian model and the method is found to be fast and accurate (joint work with Ruggero Caldana and Gianluca Fusai). 15.00 - 15.30 Jacopo Corbetta, Dottorato in Matematica e Applicazioni, Università di Milano-Bicocca Smile asymptotics in a multiscaling stochastic volatility model We consider a stochastic volatility model which captures some relevant stylized facts of financial series, including the so-called multiscaling of moments. We obtain sharp large deviations estimates for the price, based on a large deviations principle for suitable functionals of a point process, which is of independent interest. This yields explicit asymptotic formulas for the price of European options, and for the related implied volatility, both in the small maturity and large strike regimes. In particular, we show that implied volatility for out-of-the-money options explodes as the maturity vanishes, with an explicit limiting shape (joint work with Francesco Caravenna). 15.30 - 16.00 Alberto Santangelo, Dottorato in Statistica e Matematica per la Finanza, Curriculum Matematica per la Finanza, Università di Milano-Bicocca Measuring Portfolio Diversification Based on Optimized Uncorrelated Factors We measure diversification in terms of the "Effective Number of Minimum-Torsion Bets", namely a set of uncorrelated factors, optimized to closely track the factors used to allocate the portfolio. In this way we introduce a novel notion of "absolute risk contributions", which generalizes the "marginal contributions to risk" in traditional risk parity. We discuss the advantages of the Minimum-Torsion Bets over the traditional approach to diversification based on marginal contributions to risk. We present a case study in the S&P 500. Fully documented code is available for download (joint work with Romain Deguest and Attilio Meucci). Tutti gli interessati sono invitati a partecipare.

Seminario Alcuni aspetti dell'impostazione "Target-Based" alle funzioni di utilità nel caso di più "beni"
by Marco Isopi 08 Jul '14

08 Jul '14

Nell'ambito dei seminari previsti a completamento dell'attività svolta nell'ambito del Dottorato di Ricerca in Matematica XXVI Ciclo (curriculum Matematica Applicata) Fabio Fantozzi terrà un seminario dal titolo Alcuni aspetti dell'impostazione "Target-Based" alle funzioni di utilità nel caso di più "beni" Il seminario si terrà in Aula di Consiglio, Giovedi' 10 Luglio ore 16 Sunto: Verrà inizialmente richiamato il significato dell'impostazione Target-Based alla teoria dell'utilità nelle scelte economiche in condizioni di incertezza. Tale impostazione, dapprima introdotta nel caso di un singolo "bene" è stata, nell'ultimo decennio, estesa e sviluppata per il caso di n beni. Nel seminario verranno illustrate in particolare le caratteristiche fondamentali di tale caso e ne verrà introdotta una descrizione formale. In tale ambito saranno evidenziate le connessioni con le misure di insieme monotone, non necessariamente additive (capacità), su spazi finiti e relative estensioni. In particolare analizzeremo il significato di tali estensioni in termini di copule n-dimensionali atte a descrivere la dipendenza stocastica fra le componenti di un vettore aleatorio. Quest' ultimo interviene, con il significato di "target", nella formulazione delle funzioni di utilità stesse. In relazione ai problemi di scelte economiche analizzati, verranno anche brevemente illustrati degli aspetti relativi alla nozione di "stochastic precedence". *******************************************

Avviso di seminario
by Cristina Zucca 04 Jul '14

04 Jul '14

A tutti gli interessati. Mercoledì 9 luglio 2014 alle ore 14.30 in AULA C (Palazzo Campana - Dip. di Matematica"G. Peano" - Univ. di Torino) il Prof. François Delarue (Université Nice Sophia-Antipolis) terrà un seminario dal titolo: The Landau Equation for Maxwellian molecules and the Brownian Motion on the group of rotations. Abstract: We show that the spatially homogeneous Landau equation for Maxwellian molecules can be represented through the product of two elementary stochastic processes. The first one is the Brownian motion on the group of rotations. The second one is, conditionally on the first one, a Gaussian process. Using this representation, we establish sharp multi-scale upper and lower bounds for the transition density of the Landau equation, the multi-scale structure depending on the shape of the support of the initial condition. -- Dr. Cristina Zucca Department of Mathematics University of Torino Via Carlo Alberto 10 10123 Torino, Italy tel: +39-011-6702850 fax: +39-011-6702878

**************************************************************** STATISTICS SEMINARS @ COLLEGIO CARLO ALBERTO **************************************************************** Venerdi' 4 Luglio 2014 alle ore 12:00, presso la sala rossa del Collegio Carlo Alberto, Moncalieri (TO), si terra' il seguente seminario: Michael J. DANIELS (University of Texas at Austin) A FLEXIBLE BAYESIAN APPROACH TO MONOTONE MISSING DATA IN LONGITUDINAL STUDIES WITH INFORMATIVE MISSINGNESS WITH APPLICATION TO AN ACUTE SCHIZOPHRENIA CLINICAL TRIAL Abstract: We develop a Bayesian nonparametric model for a longitudinal response in the presence of nonignorable missing data. Our general approach is to first specify a {\em working model} that flexibly models the missingness and full outcome processes jointly. We specify a Dirichlet process mixture of missing at random (MAR) models as a prior on the joint distribution of the working model. This aspect of the model governs the fit of the observed data by modeling the observed data distribution as the marginalization over the missing data in the working model. We then separately specify the conditional distribution of the missing data given the observed data and dropout. This approach allows us to identify the distribution of the missing data using identifying restrictions as a starting point. We propose a framework for introducing sensitivity parameters, allowing us to vary the untestable assumptions about the missing data mechanism smoothly. Informative priors on the space of missing data assumptions can be specified to combine inferences under many different assumptions into a final inference and accurately characterize uncertainty. These methods are motivated by, and applied to, data from a clinical trial assessing the efficacy of a new treatment for acute Schizophrenia. Joint work with Antonio Linero at the University of Florida Tutti gli interessati sono invitati a partecipare. Il seminario e' organizzato dalla "de Castro" Statistics Initiative (http://www.carloalberto.org/stats) in collaborazione con il Collegio Carlo Alberto.

Seminario: Luciano Campi - presso Dipartimento di Informatica, Università di Verona
by Luca di persio 26 Jun '14

26 Jun '14

Annuncio di Seminario Luciano Campi, London School of Economics, London Giovedi' 3 Luglio, presso il Dipartimento di Informatica, Università di Verona Strada le Grazie, 15 - Sala Verde ore 15:00 (14:45 rinfresco, 15:00 inizio seminario) Title: Utility indifference valuation for non-smooth payoffs with an application to power derivatives Abstract: We consider the problem of exponential utility indifference valuation under the simplified framework where traded and nontraded assets are uncorrelated but where the claim to be priced possibly depends on both. Traded asset prices follow a multivariate Black and Scholes model, while nontraded asset prices evolve as generalized Ornstein-Uhlenbeck processes. We provide a BSDE characterization of the utility indifference price (UIP) for a large class of non-smooth, possibly unbounded, payoffs depending simultaneously on both classes of assets. Focusing then on European claims and using the Gaussian structure of the model allows us to employ some BSDE techniques (in particular, a Malliavin-type representation theorem due to Ma (2002)) to prove the regularity of Z and to characterize the UIP for possibly discontinuous European payoffs as a viscosity solution of a suitable PDE with continuous space derivatives. The optimal hedging strategy is also identified essentially as the delta hedging strategy corresponding to the UIP. Since there are no closed-form formulas in general, we also obtain asymptotic expansions for prices and hedging strategies when the risk aversion parameter is small. Finally, our results are applied to pricing and hedging power derivatives in various structural models for energy markets.

Seminario N. Leonenko a Padova- Mercoledì 2 luglio
by Marco Ferrante 21 Jun '14

21 Jun '14

Annuncio di seminario: Mercoledì 2 Luglio alle ore 12.00 in Aula 2BC30 del Dipartimento di Matematica dell'Università di Padova il Prof. Nikolai Leonenko dell'Università di Cardiff terrà il seminario Titolo: Fractional Pearson diffusions. Abstract: Pearson diffusions have stationary distributions of Pearson type. They includes Ornstein-Uhlenbeck, Cox-Ingersoll-Ross, and several others wellkown processes. Their stationary distributions solve the Pearson equation, developed by Pearson in 1914 to unify some important classes of distributions (e.g., normal, gamma, beta). Their eigenfunction expansions involve the traditional classes of orthogonal polynomials (e.g., Hermite, Laguerre, Jacobi). We develop fractional Pearson di¢ sions ([1],[2]), constructing by a non-Markovian inverse stable time change. Their transition densities are shown to solve a time-fractional analogue to the diffusion equation with polynomial coefficients. Because this process is not Markovian, the stochastic solution provides additional information about the movement of particles that di§use under this model. This is joint work with M.M. Meerschaert and A. Sikorskii (Michigan State Univeraity, USA). Anomalous diffusions have proven useful in applications to physics, geophysics, chemistry, and finance.

by Marco Ferrante 18 Jun '14

18 Jun '14

Annuncio di seminario: Giovedì 26 giugno alle ore 16.00 in Aula 2AB40 del Dipartimento di Matematica dell'Università di Padova il Prof. Carles Rovira dell'Universitat de Barcelona terrà il seminario Titolo: Stochastic differential equations with non-negativity constraints driven by fractional Brownian Abstract: In this talk, we deal with existence and uniqueness result of solution for stochastic differential driven by a fractional Brownian motion with Hurst parameter $H$ and with reflection. The cases $H >\frac12$ and $H \in (\frac13,\frac12)$ must be considered separately. When $H>\1/2$, we first study an ordinary integral equation where the integral is defined in the Young sense and then we apply this result pathwise to solve the stochastic problem. On the other hand, when H $\in (\frac13,\frac12)$, we consider an existence and uniqueness result of solution for multidimensional delay differential equations with normal reflection and driven by a H\"older continuous function of order $\beta \in (\frac13,\frac12)$.
