Dear colleagues, you are all invited to participate in the following seminar organized by QFinLab - Department of Mathematics, Politecnico di Milano. Monday, 27 January 2025, 16.00-17.00 Seminar room, third floor, building 14, Via Bonardi 9, Milano (Leonardo Campus) Adrien Mathieu (Oxford University) Title: Market Making with fads, Informed and Uninformed traders. Abstract: We characterize the solutions to a continuous-time optimal liquidity provision problem in a market populated by informed and uninformed traders. In our model, the asset price exhibits fads -- these are short-term deviations from the fundamental value of the asset. Conditional on the value of the fad, we model how informed traders and uninformed traders arrive in the market. The market maker knows of the two groups of traders but only observes the anonymous order arrivals. We study both the complete information and the partial information versions of the control problem faced by the market maker. In such frameworks, we characterize the value of information, and we find the price of liquidity as a function of the proportion of informed traders in the market. Lastly, for the partial information setup, we explore how to go beyond the Kalman-Bucy filter to extract information about the fad from the market arrivals. Next seminar: Marzia De Donno (Università Cattolica del Sacro Cuore), 19 February 12:15. All news can be found on the QFinLab webpage<https://www.qfinlab.polimi.it/seminars-and-meetings/>. The organizers: Michele Azzone and Alessandro Calvia.

OWABI - Paul Bürkner - January 30
by Massimiliano Tamborrino 14 Jan '25

14 Jan '25

Dear all, the next One World Approximate Bayesian Inference (OWABI) Seminar<https://warwick.ac.uk/fac/sci/statistics/news/upcoming-seminars/abcworldsem…> is quickly approaching, being scheduled on Thursday, the 30th January at 11am UK time. Our next speaker is Paul Bürkner<https://paulbuerkner.com/> (TU Dortmund University), who will talk about "Amortized Mixture and Multilevel Models" with an abstract reported below. Abstract: Probabilistic mixture and multilevel models are central building blocks in Bayesian data analysis. However, they remain challenging to estimate and evaluate, especially when the involved likelihoods or priors are analytically intractable. Recent developments in generative deep learning and simulation-based inference have shown promising results in scaling up Bayesian inference through amortization. Against this background, we have developed specialized neural inference frameworks for estimating Bayesian mixture and multilevel models. The involved neural architectures are closely mirroring the probabilistic symmetries and conditional (in-)dependencies assumed by these models. This not only speeds up neural network training, but also enables amortized inference for new datasets of varying number of groups and sample sizes. Keywords: Amortized Bayesian Inference; Neural Posterior Estimation; Probabilistic Factorization This and all talks are hosted on the OWABI Ms Teams Channel, which is available here https://teams.microsoft.com/l/team/19%3AdhZ_4e_XLNJzCXPAMzTvT6BZ5KShEETkd_w…. The MS Teams link to join Paul Bürkner's talk is https://teams.microsoft.com/l/meetup-join/19%3adhZ_4e_XLNJzCXPAMzTvT6BZ5KSh… Meeting ID: 361 477 079 820 Passcode: C49gr9Gx Lastly, if you missed Jeremias Knoblauch's seminar, you could now watch the recorded talk on the OWABI webpage<http://www.warwick.ac.uk/oneworldabc>.

SPASS Seminar: Rangel Baldasso
by Gianmarco Bet 13 Jan '25

13 Jan '25

Dear Colleagues, We would like to invite you to the following SPASS seminar, jointly organized by UniPi, SNS, UniFi and UniSi: *The random Markov property for random walks in random environments* by *Rangel Baldasso* (*PUC-Rio*) The seminar will take place on TUE, 21.01.2025 at *14:00 CET* in Aula Tricerri, Dipartimento di Matematica e Informatica "Ulisse Dini", Università degli Studi di Firenze, and streamed online at this link <https://meet.google.com/gji-phwo-vbg>. The organizers, A. Agazzi, G. Bet, A. Caraceni, F. Grotto, G. Zanco https://sites.google.com/unipi.it/spass -------------------------------------------- *Abstract: We consider random walks evolving in dynamic random environments and propose a criterion which, if satisfied, allows to decompose the random walk trajectory into i.i.d. increments, and ultimately to prove limit theorems. This criterion, dubbed the random Markov property, involves the construction of a random field built from the environment that has to satisfy a certain Markovian-like property along with some mixing estimates. We apply this criterion to correlated environments such as Boolean percolation and renewal chains featuring polynomial decay of correlations. Based on a joint work with Julien Allasia, Oriane Blondel, and Augusto Teixeira.*

PhD positions in Bielefeld
by Ferrari, Giorgio 09 Jan '25

09 Jan '25

Dear Colleagues, we have the great pleasure to share information on new doctoral positions within the research training group (RTG) „Coping with Uncertainty in Dynamic Economies“. This research training group is sponsored by the German Research Foundation (DFG) for up to 9 years, with approximately one million euro per year. We have successfully hired a first cohort of students in 2023, and we are now looking forward to the second cohort. The positions are fully funded, at competitive levels (approx 43.000 Euro gross per year). The RTG is an initiative of ten principal investigators from the Center for Mathematical Economics and the Data Science Research Group at Bielefeld University. Next to the well established core program of our doctoral school BiGSEM (www.bigsem.de <http://www.bigsem.de/>), students will thus work in an excellent research environment on topics involving uncertainty in its various aspects and their consequences for dynamic economies. The research training group holds strong ties with top international researchers who will give specialized block courses and summer schools. As a highlight of our program, the Mercator fellow Jean-Marc Tallon from the Paris School of Economics is part of our research training group. He will serve as a contact person for possible research stays in Paris. Please share the exciting news with your talented master students and encourage them to apply! More information can be found at the inomics website (https://inomics.com/program/9-phd-positions-in-the-research-training-group-…) and at Bielefeld’s official announcement (https://uni-bielefeld.hr4you.org/job/view/3881/research-positions-in-the-re…) Best wishes, Giorgio Ferrari
