Seminar: Riccardo Maffucci at Tor Vergata
by mic sal 09 Nov '22

09 Nov '22

Dear all, next Thursday, May 5th, Riccardo Maffucci (EPFL) will give a seminar about "Distribution of nodal intersections for random waves". Abstract: This work is in collaboration with Maurizia Rossi. Random waves are Gaussian Laplacian eigenfunctions on the 3D torus. We investigate the length of intersection between the zero (nodal) set, and a fixed surface. Expectation, and variance in a general scenario are prior work. In the generic setting we prove a CLT. We will discuss (smaller order) variance and (non-Gaussian) limiting distribution in the case of ’static’ surfaces (e.g. sphere). Under a certain assumption, there is asymptotic full correlation between intersection length and nodal area. The seminar will take place in Aula De Blasi, Università Tor Vergata, at 16h00. We encourage in-person partecipation, but should you unable to come here is the link to the event on Teams: https://teams.microsoft.com/l/meetup-join/19%3arfsL73KX-fw86y1YnXq2nk5VnZFw… The seminar is part of the Excellence Project Math@TOV.

Dear colleagues, I am happy to forward you the information regarding the following seminar organized by LTI@UniTO. The seminar can also be attended via zoom at the following link: https://us02web.zoom.us/j/86733344211?pwd=UGNoUi9CNFM5bE5SNmNaeFR6bTJsQT09 Best regards, Luca Regis LTI@UniTO and Fondazione Collegio Carlo Alberto are pleased to invite you to the following seminar: October 3, 2022 | 12:00-13:00 “How do Funds Deviate from Benchmarks? Evidence from MSCI’s Inclusion of Chinese A-shares” (joint with Lennart Dekker and Jasmin Gider) Frank de Jong (Tilburg University) Abstract. An increasing amount of assets is managed by benchmark-tracking investment funds. This study investigates how benchmarking changes affect portfolio compositions in the cross-section of different investor types and stock characteristics. To that end, we exploit the phased introduction of Chinese A-shares to the MSCI Emerging Markets index, which was announced in June 2017 and implemented over the period from May 2018 to November 2019. This change presents a rare opportunity to estimate the impact of index changes and to shed light on cross-sectional implications. We document that particularly passive funds systematically deviate from the benchmark. Market capitalization, stock liquidity and stock volatility affect how benchmark changes translate to portfolio adjustments of mutual funds and ETFs. We then study how the changes in benchmark weights affect financial market outcomes, more specifically the comovement of returns. We find that these characteristics moderate the impact of benchmarking changes on financial market outcomes, suggesting that deviations from benchmarks matter.

Dear all, Season 4 of the One Word ABC Seminar https://warwick.ac.uk/oneworldabc is starting this week on Thursday the 29th September, 1.30pm UK time.

The link to join the talk is https://bristol-ac-uk.zoom.us/j/93353511660?pwd=MmFTNUR5QkFBeStlenNVemtZbzJ… Meeting ID: 933 5351 1660 Passcode: 406075 We are looking forward to seeing you there, Best regards, Massimiliano on the behalf of the One World ABC Organisers When: 29th September, 1.30pm UK time Speaker: Till Hoffmann <https://tillahoffmann.github.io/> (Harward T.H. Chan School of Publich Health) Title: Minimizing the Expected Posterior Entropy Yields Optimal Summary Statistics Abstract: Extracting low-dimensional summary statistics from large datasets is essential for efficient (likelihood-free) inference. We propose obtaining summary statistics by minimizing the expected posterior entropy (EPE) under the prior predictive distribution of the model. We show that minimizing the EPE is equivalent to learning a conditional density estimator for the posterior as well as other information-theoretic approaches. Further summary extraction methods (including minimizing the L² Bayes risk, maximizing the Fisher information, and model selection approaches) are special or limiting cases of EPE minimization. We demonstrate that the approach yields high fidelity summary statistics by applying it to both a synthetic benchmark as well as a population genetics problem. We not only offer concrete recommendations for practitioners but also provide a unifying perspective for obtaining informative summary statistics. Reference: T. Hoffmann and J.P. Onnela.

LUISS Seminar September 29 -- prof Cristensen, link
by Sara 22 Sep '22

22 Sep '22

Dear all, this is a gentle memo of the seminar by Soren Christensen, Uni-Kiel, September 29 at 12:30 e verterà su: *Nonparametric approaches to data-driven stochastic control* Abstract: One of the fundamental assumptions in stochastic control of continuous-time processes is that the dynamics of the underlying process are known. This is, however, usually obviously not fulfilled in practice. On the other hand, a rich theory for nonparametric estimation of the characteristics of continuous-time processes has been developed over the last decades. In this talk, we discuss how to bring together these two areas for developing purely data-driven strategies for stochastic control, which we explore for ergodic impulse and singular control problems. We compare the results with those of deep-Q learning algorithms.
