Fwd: International Conference in Venice - CALL FOR PAPERS - DEADLINE May 31, 2017
by Monica BILLIO 08 May '17

08 May '17

16th INTERNATIONAL CONFERENCE CREDIT 2017 *INTEREST RATES, GROWTH and REGULATION *Venice, Italy 28-29 September 2017 *GRETA Associati *(Venice, Italy), the *European Investment Fund* (Luxembourg) and *Intesa Sanpaolo* (Milan, Italy) are co-sponsors of a Conference to be held in Venice on September 28-29, 2017. The objective of the Conference is to bring together academics, practitioners and PhD students working in the area of risk management. The conference will provide an opportunity for participants engaged in research at the forefront of this area to discuss both the causes and implications of recent events in financial markets and may, in turn, suggest fruitful directions for future research. The Conference, organised under the auspices of the *Department of Economics of the University Ca' Foscari of Venice*, *ABI - Italian Banking Association *and *European Investment Bank*, is the *sixteenth* of a series dedicated to various aspects of credit risk. Since 2007, the financial crisis has triggered deep changes of various kinds. Central banks have experimented new monetary policies (low interest rates, quantitative easing, forward guidance...). The banking industry has had to develop new asset management strategies and to adjust its credit allocation practices in order to cope with a new environment characterized, in particular, by a prolonged period of very low risk-free returns. Alternatives and complements to commercial banking have continued their progress. Meanwhile, regulatory frameworks have been reshaped all around the world, with the introduction of new requirements or guidelines. All these changes have called for a substantial amount of research to improve the knowledge of the mechanisms at play during the crisis, to design adapted policy tools and to provide a better description of the new economic and financial environment. The organizers encourage submissions of papers on any topic within the overall theme of the conference and in the following areas in particular: - Low interest rates and asset management: emergence of alternative asset classes; changes in banks asset management, repositioning towards wealth management services. - Low interest rates and econometric modelling: Zero Lower Bound; lift off; unconventional monetary policy; default risk; contagion and systemic risk. - Interest rates and alternative financing: venture capital; credit risk in p2p lending/crowdfunding, is there adverse selection? the financing of SMEs; impact on the real economy. - New regulation environment: impact of Basel 4; internal models versus standardized approach; international harmonization; impact of TLAC (total loss absorbent capacity) and IFRS9. The Scientific Committee for the Conference consists of: *Alain Monfort* (CREST-Paris, Programme Chair) *Monica Billio* (Ca' Foscari University of Venice) *Francesca Campolongo* (EU-JRC Unit 'Financial and Economic Analysis') *Helmut Kraemer-Eis* (Head EIF's Research & Market Analysis) *Jan Peter Krahnen* (SAFE - Goethe University) *Steven Ongena* (University of Zurich, SFI & CEPR) *Jean-Paul Renne* (University of Lausanne) *Fulvio Pegoraro* (Bank of France) *Bernd Schwaab* (European Central Bank) Local Organisers: *Davide Alfonsi* (Intesa Sanpaolo), *Monica Billio* (Ca' Foscari University of Venice & GRETA), *Andrea Giacomelli* (Knowshape & GRETA), *Pier Luigi Gilibert* (European Investment Fund) and *Domenico Sartore* (Ca' Foscari University of Venice & GRETA) CALL FOR PAPERS The final program will include both submitted and invited papers. Acceptances received so far from invited speakers include *Thomas Philippon *(New York University), *Manju Puri* (Duke University) and *Jean-Paul Renne* (University of Lausanne).

Seminario di probabilità e statistica matematica Lunedì 15 maggio, ore 16 Aula di Consiglio, Dipartimento di Matematica Guido Castelnuovo T.G. Kurtz, University of Wisconsin-Madison, "Stochastic equations for processes built from bounded generators" Abstract: The generator for a pure jump process with bounded jump rate is a bounded operator on the space of measurable functions. For any such process, it is simple to write a stochastic equation driven by a Poisson random measure. Uniqueness for both the stochastic equation and the corresponding martingale problem is immediate, and consequently, the martingale problem and the stochastic equation are equivalent in the sense that they uniquely characterize the same process. A variety of Markov processes, including many interacting particle models, have generators which are at least formally given by infinite sums of bounded generators. In considerable generality, we can write stochastic equations that are equivalent to these generators in the sense that every solution of the stochastic equation is a solution of the martingale problem and every solution of the martingale problem determines a weak solution of the stochastic equation. It follows that uniqueness for one approach is equivalent to uniqueness for the other. Tutti gli interessati sono invitati a partecipare. Per informazioni rivolgersi a piccioni(a)mat.uniroma1.it

************************************************************************ STATISTICS SEMINARS @ COLLEGIO CARLO ALBERTO ************************************************************************ Venerdi 12 Maggio 2017, alle ore 11.00, presso l’Aula Rossa del Collegio Carlo Alberto, Moncalieri (TO), si terra' il seguente seminario: Petros DELLAPORTAS (University College London) HIGH DIMENSIONAL JUMP PROCESSES WITH STOCHASTIC VOLATILITY We deal with the problem of identifying jumps in multiple financial time series using the stochastic volatility model combined with a jump process. We develop efficient MCMC algorithms to perform Bayesian inference for the parameters and the latent states of the proposed models. In the univariate case we use an homogeneous compound Poisson process for the modelling of the jump component. In the multivariate case we adopt an inhomogeneous Poisson process, with intensity which is also a stochastic process varying across time and economic sectors and markets. A Gaussian process is used as prior distribution for the intensity of the Poisson process. This model is known as doubly stochastic Poisson process or Gaussian Cox process. The efficiency of the proposed algorithms is compared with existing MCMC algorithms. Our methodology is tested through simulation based experiments and applied on 600 stock daily returns of Euro STOXX index over a period of 10 years. 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 Ben Goldys - Milano Bicocca 9/5
by federica.masiero＠unimib.it 03 May '17

03 May '17

Il giorno 9 Maggio, alle ore 10.45, presso il Dipartimento di Matematica e Applicazioni dell'Università di Milano-Bicocca, via Cozzi, 55, Edificio U5, stanza 3014 (terzo piano), il Prof. Ben Goldys, The University of Sydney, terrà un seminario dal titolo "Heat equation perturbed by boundary noise" Abstract: We will consider a fairly general Cauchy-Dirichlet problem with noise entering through the boundary. The case when the noise is white in space and time is also included. The question how to give a meaning to such an equation was first formulated by Da Prato and Zabczyk in 1994 and still remains largely open. We will show that the proper framework for this problem is a certain non-standard weighted $L^p$-space.This is a joint work with Szymon Peszat and Giorgio Fabbri. Tutti gli interessati sono invitati a partecipare. Cordiali saluti, Federica Masiero

Si avvisa che in data 5/5/2017, alle ore 10:30 precise, presso Aula seminari del III piano del Dipartimento di Matematica del Politecnico di Milano, nell'ambito delle iniziative della sezione di Probabilità e Statistica Matematica, si svolgerà il seguente seminario: Titolo: Invariance under quasi-isometries of subcritical and supercritical behavior in the Boolean model of percolation Relatore: Cristian Coletti, Universidade Federal do ABC, Santo André - Sao Paulo, Brasil Abstract: We study the Poisson Boolean model of percolation in locally compact Polish metric spaces and we prove the invariance of subcritical and supercritical phases under mm-quasi-isometries. More precisely, we prove that if a metric space M is mm-quasi-isometric to another metric space N, and the Poisson Boolean model in M exhibits any of the following: (a) a subcritical phase; (b) a supercritical phase; or (c) a phase transition, then the same does the Poisson Boolean model of percolation in N. We use these results in order to understand the phase transition phenomenon in a large family of metric spaces. Tutti gli interessati sono invitati a partecipare Fabio Zucca

In the present paper, we propose five alternative models based on strength parameters that are determined by maximum likelihood estimation. We conduct a comparison of these five statistical models, to which we add the ELO model used for the women's FIFA ranking, on grounds of their predictive performance. Indeed, contrary to regular league rankings, the FIFA ranking is designed to measure the current strength of teams, hence should allow accurate predictions of future matches. Our comparison is based on fifteen English Premier League seasons. The best performing model is then used to build the alternative FIFA ranking. We furthermore show its predictive power by analyzing the 2016 European Championship and comparing our predictions to the bookmaker ratings, usually considered as golden standard. Tutti gli interessati sono invitati a partecipare. -- %------------------------------------------------------- Elvira Di Nardo Dept. Mathematics "G.

Annuncio Seminario di Probabilita, Pisa, Universita' di Pisa Martedi' 2 maggio, ore 11:00, Aula Seminari Seminario di Probabilita’ SPEAKER: Konstantin Matetski (University of Toronto) TITLE: Convergence of general weakly asymmetric exclusion processes ABSTRACT: In my ongoing work with J. Quastel we consider spatially periodic growth models built from weakly asymmetric exclusion processes with finite jump ranges and general jump rates. We prove that at a large scale and after renormalization these processes converge to the Hopf-Cole solution of the KPZ equation driven by Gaussian space-time white noise. In contrast to the celebrated result by L. Bertini and G. Giacomin (in the case of the nearest neighbour interaction) and its extension by A. Dembo and L.-C. Tsai (for jumps of sizes at most three) we don’t use the Hopf-Cole transform and work with the KPZ equation using regularity structures. The price which we have to pay for this approach is a non-trivial renormalization which has not been observed before for equations with stationary noises. In my talk i will give a general review of the Hopf-Cole solution to the KPZ equation and the results of the aforementioned authors. After that I will introduce a general weakly asymmetric exclusion process and explain the difficulty with renormalization. Tutti gli interessati sono invitati a partecipare.

Seminario di F. den Hollander a Milano-Bicocca (10.05.2017)
by Francesco Caravenna 27 Apr '17

27 Apr '17

Mercoledì 10 maggio 2017 alle ore 14:30, nell'ambito del Seminario Matematico e Fisico di Milano, Frank den Hollander (Leiden University) terrà un seminario dal titolo "Random walks on dynamic random graphs" Aula 3014, Dipartimento di Matematica e Applicazioni (edificio U5, via Cozzi 55, Milano) Università di Milano-Bicocca Trovate il sommario di seguito. Tutti gli interessati sono invitati a partecipare. Francesco Caravenna %%%%%%%%%%%%%%%%%%%%%%%% The mixing time of a random walk is the time it needs to approach its stationary distribution. For random walks on graphs, the characterisation of the mixing time has been the subject of intensive study. One of the motivations is the fact that the mixing time gives information about the geometry of the graph. In the last few years, much attention has been devoted to the analysis of mixing times for random walks on \emph{random graphs}, which poses interesting challenges. Many real-world networks are dynamic in nature. It is therefore natural to study random walks on \emph{dynamic random graphs}. In this talk we consider a random walk on the configuration model, i.e., a random graph with prescribed degrees. We investigate what happens when at each unit of time a fraction $\alpha_n$ of the edges is randomly relocated, where $n$ is the number of nodes. We identify \emph{three regimes} for the mixing time in the limit as $n \to \infty$, depending on the choice of $\alpha_n$. These regimes exhibit surprising behaviour. Joint work with Luca Avena (Leiden), Hakan Guldas (Leiden) and Remco van der Hofstad (Eindhoven) %%%%%%%%%%%%%%%%%%%%%%%% _________________________________________ Francesco Caravenna Dipartimento di Matematica e Applicazioni Università degli Studi di Milano-Bicocca Via Cozzi 55, 20125 Milano, Italy http://www.matapp.unimib.it/~fcaraven/ _________________________________________

Seminario di probabilità e statistica matematica Martedì 2 maggio, ore 14 Aula di Consiglio, Dipartimento di Matematica Guido Castelnuovo Cristina Costantini, Università D'Annunzio Chieti-Pescara LA DIFFUSIONE DI POISSON-DIRICHLET A DUE PARAMETRI COME LIMITE DI MODELLI DI GENETICA Riassunto: Oltre alle ben note applicazioni in statistica Bayesiana, teoria dei numeri, ecc., la distribuzione di Poisson-Dirichlet ha un’importante signiﬁcato in genetica: infatti e’ l’unica distribuzione stazionaria della diﬀusione che descrive il comportamento delle frequenze, ordinate in ordine decrescente, degli alleli presenti in una popolazione, al tendere all’inﬁnito della dimensione della popolazione e del numero di alleli. La distribuzione di Poisson-Dirichlet a due parametri e’ una generalizzazione della distribuzione di Poisson-Dirichlet che emerge in particolare nello studio delle escursioni del moto Browniano e nella teoria del rinnovo. Nel 2009 Petrov ha costruito una diﬀusione che ammette la distribuzione di Poisson-Dirichlet a due parametri come unica distribuzione stazionaria. Fino a oggi pero’ non era stato possibile collegare questa diﬀusione a modelli di genetica. Nel seminario esporro’ un recente risultato, ottenuto in collaborazione con P. De Blasi, S. Ethier, M. Ruggiero, D. Spano`, che dimostra che la diﬀusione costruita da Petrov e’ il limite, al tendere all’inﬁnito della dimensione della popolazione e del numero di alleli, di modelli di genetica che descrivono l’evoluzione delle frequenze, ordinate in ordine decrescente, degli alleli nella popolazione, in presenza non solo di mutazioni, ma anche di immigrazione da un’altra popolazione. Tutti gli interessati sono invitati a partecipare. Per informazioni rivolgersi a piccioni(a)mat.uniroma1.it

Seminario Fausto Gozzi 20 aprile 2017 presso Università Cattolica sede di Milano

Seminario di Fausto Gozzi (Dipartimento di Economia e Finanza - Università LUISS Guido Carli) Giovedi' 20 aprile 2017 - ore 10:30 - aula 200 Università Cattolica del Sacro cuore, Milano, Dipartimento di Discipline matematiche, Finanza matematica ed Econometria Via Necchi, 9 - Milano TITLE: Optimal portfolio choice with path dependent labor income: The infinite horizon case ABSTRACT: We consider an infinite horizon portfolio choice problem with borrowing constraints where an agent receives labor income that adjusts slowly to financial market shocks. The novelty of the model is the path-dependence of the wage income process, which leads to an infinite dimensional stochastic optimal control problem. We solve completely the problem, and find explicitly the optimal controls in feedback form. This is possible because we are able to find an explicit solution to the associated infinite dimensional Hamilton-Jacobi-Bellman (HJB) equation, even if state constraints are present. To the best of our knowledge, this is the first infinite dimensional generalization of Merton's optimal portfolio problem where explicit solutions can be found. The explicit solution allows us to study and discuss the behavior of optimal solutions. We conclude, if there is time, by showing how the solution strategy used here can be deployed to solve other problems, such as the finite horizon version of the model. Joint work with Enrico Biffis and Cecilia Prosdocimi Tutti gli interessati sono invitati a partecipare.
