seminario Carlo Sala in Bicocca
by fabio bellini 15 Dec '17

15 Dec '17

Il giorno martedì 19 dicembre alle ore 14.30, presso la aula demografica del DISMEQ al secondo piano dell'edificio U7 della Università di Milano-Bicocca, il dott. Carlo Sala dell'ESADE di Barcellona terrà un seminario su S&P 500 Index, an Option-Implied Risk Analysis Abstract The forward-looking nature of option market data allows one to derive economically-based and model-free conditional risk measures. The option-implied methodology overcomes the elicitability issue and is an interesting tool for regulators and companies to perform external or internal risk analysis without posing assumptions on the distribution of returns. The article proposes the first comprehensive analysis of the performances of these measures compared with classical risk measures for the S&P500. The option-implied estimates deliver good results during the financial crisis and emerge as a convenient alternative to the existing risk measures. Tutti gli interessati sono invitati a partecipare. -- Prof. Fabio Bellini Department of Statistics and Quantitative Methods University of Milano-Bicocca Via Bicocca degli Arcimboldi 8, 20126 Milano 0039-2-64483119 http://scholar.google.it/citations?user=P61L8P4AAAAJ&hl=it

de Finetti Risk Seminar - December 21
by Emanuela Rosazza 14 Dec '17

14 Dec '17

On behalf of the Scientific Committee of the de Finetti Risk Seminars, we are glad to invite you to participate at the following Lecture TITLE: Probability measure valued polynomial processes Christa Cuchiero University of Vienna ABSTRACT: We introduce polynomial diffusions taking values in the space of probability mea- sures on a locally compact Polish space, generalizing the well-known Fleming-Viot process. We provide a representation of the corresponding extended generators, and prove well- posedness of the associated martingale problems. In particular, we obtain uniqueness by establishing a formula for the conditional moments of the solution, which in the finite-dimensional case reduces to a matrix exponential. The talk is based on joint work with Martin Larsson and Sara Svaluto Ferro. LOCATION: The seminar will be held on Thursday, December 21, at 17.00, Aula di rappresentanza, Dept. of Mathematics, Milano University, Via C. Saldini 50, Milano.

************************************************************************ STATISTICS SEMINARS @ COLLEGIO CARLO ALBERTO ************************************************************************ Mercoledì 20 Dicembre 2017, alle ore 11:30, presso il nuovo edificio del Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terra' il seguente seminario: ------------------------------------------------ John ARMSTRONG (King’s College London) STOCHASTIC DIFFERENTIAL EQUATIONS AS JETS We explain how Ito Stochastic Differential Equations (SDEs) on manifolds may be defined using 2-jets of smooth functions. We show how this relationship can be interpreted in terms of a convergent numerical scheme. We show how jets can be used to derive graphical representations of Ito SDEs and how jets give rise to a coordinate free approach to understanding SDEs and diffusions on manifolds. We will consider some applications of this approach. ------------------------------------------------ Tutti gli interessati sono invitati a partecipare. Il seminario e' organizzato dalla "de Castro" Statistics Initiative (www.carloalberto.org/stats <http://www.carloalberto.org/stats>) in collaborazione con il Collegio Carlo Alberto.

Seminario Luciano Campi a L'Aquila
by Fabio Antonelli 11 Dec '17

11 Dec '17

Il giorno 18 dicembre 2017 alle ore 12:30 presso il Laboratorio di Didattica della Matematica (Coppito 1 piano terra) il prof. Luciano Campi - London School of Economics terrà il seminario Nonzero-sum stochastic differential games with impulse controls: a verication theorem with applications Abstract: We consider a general nonzero-sum impulse game with two players. The main mathemat- ical contribution of the paper is a verication theorem which provides, under some regularity conditions, a suitable system of quasi-variational inequalities for the value functions and the optimal strategies of the two players. As an application, we study an impulse game with a one-dimensional state variable, following a real-valued scaled Brownian motion, and two players with linear and symmetric running payos. We fully characterize a Nash equilibrium and provide explicit expressions for the optimal strategies and the value functions. We also prove some asymptotic results with respect to the intervention costs. Finally, we consider two further non-symmetric examples where a Nash equilibrium is found numerically. Fabio Antonelli

Seminario M. Maurelli a Pisa, 18 dicembre
by Marco Romito 11 Dec '17

11 Dec '17

Dear all, I would like to announce the following talk in the probability seminar at the University of Pisa. DATE AND TIME: Monday, December 18, 15:00h - 16:00h LOCATION: Aula Seminari, Dipartimento di Matematica, Universita' di Pisa SPEAKER: Mario Maurelli (Weierstrass Institute for Applied Analysis and Stochastics, Berlin, & Technische Universität Berlin) TITLE: A McKean-Vlasov SDE with reflecting boundaries ABSTRACT: McKean-Vlasov SDEs are SDEs where the coefficients depend on the law of the solution to the SDE. Their interest is in the links with nonlinear PDEs on one side (the SDE-related Fokker-Planck equation is nonlinear) and with interacting particles on the other side (the McKean-Vlasov SDE can be approximated by a system of weakly coupled SDEs). In this talk, motivated by a model of lithium-ion batteries, we introduce a McKean-Vlasov SDE constrained on a bounded domain. The novelty lies in the particular interplay between the mean field interaction and the boundary conditions. We study well-posedness and particle approximation. Our analysis combines techniques for SDEs with Neumann boundary terms (Skorokhod equation, Lions-Sznitman) and ideas from a recent approach to McKean-Vlasov SDEs (Cass-Lyons). Everyone is invited to participate.

de Finetti Risk Seminar - December 2017
by emanuela rosazza gianin 10 Dec '17

10 Dec '17

On behalf of the Scientific Committee of the de Finetti Risk Seminars, we are glad to invite you to participate at the following Lecture Learning Consumer Tastes from Dynamic Assortments: A Nonparametric Bayesian Model Canan Ulu Georgetown University Abstract. We study dynamic assortment decisions of a firm learning about consumer tastes by observing sales of the products offered. Each period, the firm offers an assortment to maximize expected total profits over a finite horizon given its subjective beliefs on consumer tastes. The consumers choose a product that maximizes their own utility and the firm updates its beliefs on consumer tastes after having observed the sales of each product in the assortment. We model consumer tastes as locations on a Hotelling line and develop a nonparametric Bayesian learning model using Polya tree priors that makes no assumptions on the form of the consumer taste distribution. Our nonparametric learning model results in optimal profits that are robust to misspecification in the consumer taste distribution. We develop upper bounds on the firm’s total profit based on information relaxations and study the performance of various heuristic policies with respect to these upper bounds. LOCATION: The seminar will be held on Wednesday, December 13, at 18.00 at room 3-E4-SR03, Bocconi University, Via Rontgen <https://maps.google.com/?q=Via+Rontgen+1&entry=gmail&source=g> 1, 3rd floor, Milano.
