Ait-Sahalia seminar in Verona, 14/3/2025
by Cecilia Mancini 28 Feb '25

28 Feb '25

Professor Yacine Ait-Sahalia will give the seminar So Many Jumps, So Little News At the Department of Economics of the University of Verona, on Friday, March 14, 2025, at noon (12 pm) Via Cantarane 24, Vaona Room, 1st floor It will be possible also to attend on Zoom here https://univr.zoom.us/j/93150650381 All the interested people are warmly invited to attend Abstract This paper relates jumps in high frequency stock prices to firm-level, industry and macroeconomic news, in the form of machine-readable releases from Thomson Reuters News Analytics. We find that most relevant news, both idiosyncratic and systematic, lead quickly to price jumps, as market efficiency suggests they should. However, in the reverse direction, the vast majority of price jumps do not have identifiable public news that can explain them, in a departure from the ideal of a fair, orderly and efficient market. We show that jumps without news do not correlate with observable proxies for asymmetric or private information, and that microstructure-driven variables have only limited power to help predict the occurrence of jumps without news.

Due modi ci sono per non soffrirne. Il primo riesce facile a molti: accettare l'inferno e diventarne parte fino al punto di non vederlo più. Il secondo è rischioso ed esige attenzione e apprendimento continui: cercare e saper riconoscere chi e cosa, in mezzo all'inferno, non è inferno, e farlo durare, e dargli spazio. Italo Calvino

Seminar Brunero Liseo @Luiss
by Alessia Caponera 28 Feb '25

28 Feb '25

Dear all, The Department of Economics and Finance at Luiss University in Rome (*https://economiaefinanza.luiss.it <https://economiaefinanza.luiss.it/>*) is pleased to announce the following seminar: *Speaker*: Brunero Liseo, Sapienza University of Rome *Title*: A Multivariate Copula-Based Conformal Bayesian Framework for Doping Detection *When*: March 6th, 14:30 *Where*: Viale Romania, 32 00197 Rome *Meeting room*: 405 *Abstract*: Doping control is an essential component of anti-doping organizations for protecting sports competitions. Since 2009, this mission has been complemented worldwide by the Athlete Biological Passport (ABP), which monitors athletes’ profiles over time. The practical implementation of the ABP is based on a Bayesian framework, called ADAPTIVE, intended to identify individual reference ranges outside of which an observation may indicate doping abuse. Currently, this method follows a univariate approach, relying on simultaneous analysis of different markers. This work extends the ADAPTIVE method to a multivariate testing framework, making use of copula models to couple the marginal distribution of biomarkers with their dependence structure. After introducing the proposed copula-based hierarchical model, we discuss our approach to inference, grounded in a Bayesian spirit, and present an extension to multidimensional predictive reference regions. We guarantee exact coverage of the regions through the use of a conformal prediction approach. Focusing on the hematological module of the ABP, we evaluate the proposed framework in both data-driven simulations and real data. Based on joint work with Nina Deliu. *Webpage*: https://economiaefinanza.luiss.it/research-seminar/a-multivariate-copula-ba… *Should you be interested, please kindly send me an e-mail.* Best wishes, Alessia Caponera

Reminder: Summer School PREDICT - Como Lake, June 16-20, 2025
by Gianmarco Bet 27 Feb '25

27 Feb '25

Dear Colleagues, We would like to remind you that the Summer School PREDICT-PRobabilistic mEthoDs In Complex geometry, will take place at Como Lake, from June 16 to June 20, 2025. There are a few spots left, so we decided to postpone the application deadline to *March 9, 2025*. At this page https://sites.google.com/view/predictcomolake/registration you can find all the information about registration. The aim of this school is to explore how probabilistic techniques can be applied to central problems in complex geometry, with a special focus on the construction of Kähler-Einstein metrics—a topic of significant interest in both geometry and physics. The school includes foundational mini-courses as well as advanced courses on recent research results. Due to the novelty of the topic, the school is designed for Master and Ph.D. students, and of course also for more established researchers. Please see the following page https://sites.google.com/view/predictcomolake/program for the detailed program. For questions, please contact us at predictcomo2025(a)gmail.com We look forward to welcoming you in Como! Warm regards, The organisers Luisa Andreis, Daniele Angella, Luca Avena, Giovanni Bazzoni, Gianmarco Bet e Michela Zedda

seminar Irene Gijbels @ CNR Naples
by Daniela De Canditiis 27 Feb '25

27 Feb '25

Cari tutti per il ciclo *"Seminari Generali IAC 2025"* *martedì 4 marzo 2025 *alle ore *14:30* Irène Gijbels, Department of Mathematics, University of Leuven (KU Leuven), Belgium, terrà il seminario: *Measures of asymmetry for multivariate distributions* *Abstract* - In univariate settings the notion of measuring skewness of a distribution is well established. Extending this to measuring skewness (or asymmetry) in a multivariate setting is less obvious. In this talk we start by briefly reviewing some notions of asymmetry measures. We next propose a novel functional asymmetry measure (index) which is based on the natural idea of reflective symmetry around the mode. The proposed index is extended to the multivariate setting and a summarizing scalar (or vector based index in multivariate settings) is derived from it. Some illustrative examples are provided, and estimation of the proposed asymmetry index is discussed in parametric and nonparametric (multivariate) settings. Il seminario si svolgerà presso la sede *CNR-IAC di Napoli*, *sala conferenze “Vaccaro”*, in modalità mista: in presenza e in streaming al link *https://www.youtube.com/watch?v=eEPimm1_aww <https://www.youtube.com/watch?v=eEPimm1_aww>* Si ricorda che i seminari del ciclo si terranno di *martedì alle 14:30*, *a settimane alterne*, *salvo eccezioni* a partire da martedì 14 gennaio 2025. *Qui la pagina web dei seminari*: *https://www.iac.cnr.it/seminari-generali-iac-2025* <https://www.iac.cnr.it/seminari-generali-iac-2025> *VI ASPETTIAMO!* (organizzatori: Nicola Apollonio, Roberta Bianchini, Claudia Capone, Giuliana Ramella) -- Daniela De Canditiis, PhD Istituto per le Applicazioni del Calcolo "M.Picone" (CNR) via dei Taurini, 19 -- 00185 Roma, Italy tel: +39 06 49937342 fax: +39 06 4404306 https://www.iac.cnr.it/personale/daniela-de-canditiis

QFinLab Seminar - Katia Colaneri (Università di Roma Tor Vergata) - 5/3/2025, 12:00 @ Department of Mathematics, Politecnico di Milano
by Alessandro Calvia 26 Feb '25

26 Feb '25

Dear colleagues, you are all invited to participate in the following seminar organized by QFinLab - Department of Mathematics, Politecnico di Milano. Wednesday, 5 March 2025, 12.00-13.00 Seminar room, third floor, building 14, Via Bonardi 9, Milano (Leonardo Campus) Katia Colaneri (Università di Roma Tor Vergata) Title: Expect the worst! Optimal emission abatement under tax policy uncertainty and stochastic differential games. Abstract: We study the problem of a profit maximizing electricity producer who has to pay carbon taxes and who decides on investments into technologies for the abatement of CO emissions in an environment where carbon tax policy is random and where the investment in the abatement technology is divisible, irreversible and subject to transaction costs. We consider two approaches for modelling the randomness in taxes. First we assume a precise probabilistic model for the tax process, namely a pure jump Markov process (so-called tax risk); this leads to a stochastic control problem for the investment strategy. Second, we analyze the case of an uncertainty-averse producer who uses a differential game to decide on optimal production and investment. We carry out a rigorous mathematical analysis of the producer's optimization problem and of the associated nonlinear PDEs in both cases. Numerical methods are used to study quantitative properties of the optimal investment strategy. We find that in the tax risk case the investment in abatement technologies is typically lower than in a benchmark scenario with deterministic taxes. However, there are a couple of interesting new twists related to production technology, divisibility of the investment, tax rebates and investor expectations. In the stochastic differential game on the other hand an increase in uncertainty might stipulate more investment. Next seminar: Claudio Fontana (Università di Padova), 2 April 12.00. All news can be found on the QFinLab webpage<https://www.qfinlab.polimi.it/seminars-and-meetings/>. The organizers: Michele Azzone and Alessandro Calvia
