Seminario di Flavia Barsotti presso Prometeia - Bologna
by Giacomo Scandolo 29 Jun '15

29 Jun '15

Il giorno Giovedì 2 Luglio 2015, alle ore 14:30 presso la sede di Prometeia (sala grande, primo piano) via G.Marconi 43, Bologna Flavia BARSOTTI Risk Methodologies, Group Financial Risk, Group Risk Management, UniCredit S.p.A. terrà un seminario dal titolo "Credit risk evaluation: performance and determinants of structural modeling approach" Abstract Structural credit risk models are known to be the natural mathematical framework providing a theoretical link between a firm’s default probability and the underlying firm’s specific structural variables. In this spirit, this talk discusses the ability of structural credit risk modeling in measuring the sensitivity of corporate bond returns to changes in equity value, representing a key element for hedging purposes in risk management activity. The analysis is conducted by considering as starting point the classical Merton model. Extensions of this setting are proposed by relaxing the assumption of Lognormal distribution for the underlying assets value dynamics. The talk discusses the performance of structural models across different rating classes and analyzes which are the key determinants (both credit and non-credit related variables) affecting the performance. --- Questa e-mail è priva di virus e malware perché è attiva la protezione avast!

Seminar Prof. Jorge Zubelli in Padova
by Giorgia Callegaro 26 Jun '15

26 Jun '15

Dear all, next week, the 3rd July 2015, Prof. Jorge Zubelli (IMPA, Rio De Janeiro) will give a seminar on Real Options (Mathematics/Probability applied to Finance) from 12am to 13 am, in room 2BC30 at "Torre Archimede" (Dep. of Mathematics, University of Padova). More details, i.e., the title and abstract follow: Title: "Project evaluation and Real Option Analysis: A Hedged Monte Carlo Approach" Abstract: Industrial strategic decisions have evolved tremendously in the last decades towards a higher degree of quantitative analysis. Such decisions require taking into account a large number of uncertain variables and volatile scenarios, much like financial market investments. Furthermore, they can be evaluated by comparing portfolios of investments in financial assets such as in stocks, derivatives and commodity futures. This revolution led to the development of a new field of managerial science known as Real Options. The use of Real Option techniques incorporates also the value of flexibility and gives a broader view of many business decisions that brings in techniques from quantitative finance and risk management. Such techniques are now part of the decision making process of many corporations and require a substantial amount of mathematical background. Yet, there has been substantial debate concerning the use of risk neutral pricing and hedging arguments to the context of project evaluation. We discuss some alternatives to risk neutral pricing that could be suitable to evaluation of projects in a realistic context with special attention to projects dependent on commodities and non-hedgeable uncertainties. More precisely, we make use of a variant of the hedged Monte-Carlo method of Potters, Bouchaud and Sestovic to tackle strategic decisions. Thanks for the attention and have a nice day, Giorgia -- Giorgia Callegaro Assistant Professor Department of Mathematics - University of Padova Via Trieste 63 , I-35121 Padova - ITALY Tel: +39-0498271481 Fax: +39-0498271499 E-Mail: gcallega(a)math.unipd.it <https://webmail.math.unipd.it/horde3/imp/message.php?mailbox=Sent&index=598#> Personal web-page: https://sites.google.com/site/giogiocallegaro/Home

Seminario Dottor Enrico Moretto all'IMATI
by Antonella Bodini 24 Jun '15

24 Jun '15

Si comunica che il giorno 2 luglio alle ore 10.30, presso la sala A della sede di Milano dell'IMATI, Via E. Bassini 15, il Dottor Enrico Moretto, dell'Universita' dell'Insubria, terra' il seminario dal titolo *Alcune applicazioni finanziarie dello stochastic dividend discount model.* Abstract: lo /stochastic dividend discount model/ (SDDM) (Hurley e Johnson, 1994 e 1998) ha esteso in un contesto aleatorio la classica formula di Gordon che determina il prezzo di un'azione attualizzando i futuri dividendi pagati dalla società agli azionisti. Il modello ipotizza che i dividendi si evolvano in tempo discreto in maniera stocastica, pilotati da un tasso di crescita aleatorio. I contributi di ricerca che saranno presentati rappresentano il tentativo di applicare lo SDDM ad alcuni problemi ben noti in finanza, quali la teoria di selezione del portafoglio e l'analisi delle fusioni tra società. Tutti gli interessati sono invitati a partecipare. Cordiali saluti, Antonella Bodini -- Dott. Antonella Bodini CNR-Istituto di Matematica Applicata e Tecnologie Informatiche Via Bassini 15, 20133 Milano (Italy) tel +39 02 23699524 fax +39 02 23699538 http://www.mi.imati.cnr.it/~anto/

*Giovedi' 25 Giugno*,*ore 12:00* Consiglio Nazionale delle Ricerche, Istituto per le Applicazioni del Calcolo "M. Picone", via dei Taurini 19, 00185 Roma Aula Riunioni (I piano) *Simon Campese* (Universita' di Roma "Tor Vergata") terra' un seminario dal titolo *Fourth Moment Theorems for non-linear approximation* ABSTRACT: In the context of non-linear approximation, the classical Fourth Moment Theorem provides a very general framework where convergence of only the second and fourth moment is enough to ensure convergence towards a Gaussian. We will provide an overview of the theory, including multivariate extensions, quantitative results and versions for other target laws such as the Gamma or Beta distribution. Apart from basic knowledge of functional analysis, no further preliminaries are needed. Tutti gli interessati sono invitati a partecipare.

No Free Lunch Seminar by Roberto Casarin, Thu July 2 1:00 PM Aula Bianchi @ SNS
by Giacomo Bormetti 19 Jun '15

19 Jun '15

Dear all, Thu Jul 2 2015, 1:00 PM in Aula Bianchi, Scuola Normale Superiore Pisa Roberto Casarin Department of Economics - Università Ca' Foscari di Venezia will deliver the seminar "Bayesian Nonparametric Calibration and Combination of Predictive Distributions" Abstract: We introduce a Bayesian approach to predictive density calibration and combination that accounts for parameter uncertainty and model set incompleteness through the use of random calibration functionals and random combination weights. Building on the work of Ranjan and Gneiting (2010) and Gneiting and Ranjan (2013), we use infinite beta mixtures for the calibration. The proposed Bayesian nonparametric approach takes advantage of the flexibility of Dirichlet process mixtures to achieve any continuous deformation of linearly combined predictive distributions. The inference procedure is based on Gibbs sampling and allows accounting for uncertainty in the number of mixture components, mixture weights, and calibration parameters. The weak posterior consistency of the Bayesian nonparametric calibration is provided under suitable conditions for unknown true density. We study the methodology in simulation examples with fat tails and multimodal densities and apply it to density forecasts of daily S&P returns and daily maximum wind speed at the Frankfurt airport. Joint work with Federico Bassetti and Francesco Ravazzolo. All interested people are kindly invited.
