Thursday, 3 October, 12:00 Luiss | Viale Romania, 32 | Room 207 Yosi Rinott, Hebrew University of Jerusalem Title Priors and Posteriors of Asset Values, Domination, Optimism, and Monotonicity Abstract Suppose there is a set of states that are relevant to the value of an asset, and the market has a prior distribution on the state space. Consider signals having distribution depending on the true state. The price of an asset depends on the market’s posterior probability that the asset is in a good state, given a signal. Before the signal is given, the market considers the expectation of this (random) posterior probability, and more generally, its distribution. It is well known that the expected posterior equals the prior, but the actual posterior probability may be higher or lower than the prior depending on the signal. Suppose an insider has a different prior than the market. We study the question of what kind of priors will make the insider expect that the asset value following the signal will be higher than the market’s value (suggesting to buy, or to be optimistic). Since the posterior is a random variable, this leads to stochastic ordering, and in fact, we obtain a very strong ordering, namely likelihood ratio order. Given such a setup, if signals are generated independently according to a given state, then Doob’s Bayesian Consistency Theorem says that the posterior probability of this state converges to one. We study some monotonicity properties of this convergence, and some (perhaps) surprising lack of monotonicity. ******************************************************* Marco Scarsini Dipartimento di Economia e Finanza Luiss Viale Romania 32 00197 Roma, ITALY URL: http://docenti.luiss.it/scarsini/

Seminario di Claudio Macci presso l’Università di Salerno
by Barbara Martinucci 01 Oct '19

01 Oct '19

Il Prof. Claudio Macci (Università di Roma Tor Vergata) terrà il seguente seminario mercoledì 9 ottobre alle ore 16.00 presso la sala riunioni del Dipartimento di Matematica dell’Università di Salerno: *Titolo*: "Multivariate fractional (possibly compound) Poisson processes " *Abstract:* We present multivariate space-time fractional Poisson processes by considering common random time-changes of a finite-dimensional vector of independent classical (non fractional) Poisson processes. In some cases we also consider compound processes. We obtain some equations in terms of some suitable fractional derivatives and fractional difference operators, which provides the extension of known equations for the univariate processes. In particular we show that, for each fixed t≥0, the conditional joint distribution of the components given their sum is multinomial, as happens for the non fractional Poisson processes. Thus we consider a suitable multivariate "alternative" fractional Poisson process, and we study its asymptotic behavior for large times (large and moderate deviations). The results appear in two papers with Luisa Beghin Cordiali saluti, Barbara Martinucci

🆕 Intensive Research Programme in Quantitative Finance
by Maria Elvira Mancino 30 Sep '19

30 Sep '19

Da: "Centre de Recerca Matemàtica (CRM)" difusions(a)crm.cat Cc: Data: Mon, 30 Sep 2019 12:18:34 +0000 Oggetto: 🆕 Intensive Research Programme in Quantitative Finance View this email in your browser [1] Dear colleague, we are pleased to announce the forthcoming CRM Intensive Research Programme in QUANTITATIVE FINANCE JUNE – JULY 2020 Centre de Recerca Matemàtica (BARCELONA) This intensive program focuses in hot topics in Quantitative Finance. In the last decades, problems emerging in the financial industry have been a starting point for the development of quantitative techniques. These techniques cover a wide spectrum of mathematical fields, from probability theory to numerical and computational tools. A huge volume of research has done in the academia inspired by these problems. In the contrary direction, the financial industry is using more and more advanced (from the mathematical point of view) tools and concepts, due to the increasing complexity of markets, that can only be addressed with high-level quantitative methods. This program has been designed to create a bridge between the academia and the industry and it is thought to be a forum to gather professionals working in this area. This means, from the academia, the financial industry and specialized software companies. The program will last for two months and it will take place at the Centre de Recerca Matemàtica during the period June-July 2020. The program is composed of: ADVANCED COURSE ON NUMERICAL METHODS IN FINANCE [2]. June 8th to 12th, 2020 ADVANCED COURSE ON STOCHASTIC TOOLS IN FINANCE [3]. June 15th to 19th, 2020 WEEKLY SEMINARS FOR RESEARCHERS. June 22nd to July 24th, 2020 WEEKLY SEMINARS FOR STUDENTS. June 22nd to July 24th, 2020 WORKSHOP: NEW CHALLENGES IN QUANTITATIVE FINANCE [4]. July 13th to 17th, 2020 ORGANIZERS: Elisa Alòs Universitat Pompeu Fabra Luis Ortiz-Gracia Universitat de Barcelona Josep Vives Universitat de Barcelona-IMUB SCIENTIFIC COMMITTEE: Elisa Alòs Universitat Pompeu Fabra José Manuel Corcuera Universitat de Barcelona Maria Elvira Mancino Università di Firenze Cornelis W.

Seminar Panaretos @Bocconi
by Giacomo Zanella 27 Sep '19

27 Sep '19

We announce the following DEC Statistics seminar: Thursday, October 3 12:30 Meeting room 3-e4-sr03, Bocconi University, Via Roentgen 1, 3rd floor Victor Panaretos (École Polytechnique Fédérale de Lausanne) Title: Fréchet Means and Procrustes Analysis in Wasserstein Space Abstract: Given a collection of diffuse random measures in R^d, we consider the problems of: constructing their optimal multicoupling in a mean square sense (a.k.a. Procrustes analysis); and of determining their Fréchet mean with respect to the Wasserstein metric. Though these problems admit explicit solutions when d=1, they are considerably more challenging when d>1. To attack them, we exploit the geometry of Wasserstein space, and specifically the relation between its tangent bundle and the class of optimal coupling maps. This allows us to determine the gradient of the Fréchet functional and show that the two problems at hand represent two sides of the same coin: gradient descent for the Fréchet mean reduces to a Procrustes algorithm, requiring only successive solution of pairwise coupling problems, thus being practically feasible; and the optimal maps obtained as a bye-product can be used to explicitly construct the optimal multi-coupling. We show how these results can be used in order to consistently solve the problem of registration of warped spatio-temporal point processes in an entirely nonparametric fashion, by means of appropriate regularisation. Kind regards, Giacomo Zanella The DEC statistics seminars schedule is available at http://www.unibocconi.eu/statseminar Please note: if you are a guest and you do not have a Bocconi ID Card to access to the Bocconi Buildings, please communicate your participation by sending an email to arianna.colombo(a)unibocconi.it

seminario Fabio Antonelli a Roma Tor Vergata
by Anna Vidotto 27 Sep '19

27 Sep '19

Dear all, I would like to announce the following talk that will be held on Friday, October 4th 2019, at 4:30 PM, in Aula Dal Passo of the Department of Mathematics, University of Rome Tor Vergata. Speaker: Fabio Antonelli Title: CVA and vulnerable options in stochastic volatility model Abstract: CVA adjustment in order to evaluate correctly derivatives subject to default risk has become more and more important in the past decade, especially when Wrong Way Risk, that is an increase in the product's price when deterioration of credit occurs. Considering the most common stochastic volatility models, we express WWR in terms of the correlation between asset's price and default event, that is described exploiting the so called intensity approach. When intensity follows an affine process, we are able to parametrize this correlation and, applying accurately Ito's formula, to suggest a Taylor polynomial approximation of CVA. Some numerical results showing the efficiency of the method are provided.
