LTI@UniTO seminars | Christopher Polk, May 2nd and Andrea Tamoni, May 3rd @12.00
by Luca Regis 24 Jun '23

24 Jun '23

Dear Colleagues, it is my pleasure to invite you to the following two seminars in Quantitative Finance, organised by LTI@UniTO (www.carloalberto.org/lti) and Collegio Carlo Alberto (CCA), which will take place at CCA in Torino and can be followed via Zoom. At the event page link you can find the paper, the zoom link to attend online and a button to add the event to your calendars. ------------------------------------------------------------------------------------------- May 2nd @ 12.00 Speaker: Christopher Polk (LSE) Title: The Day Destroys the Night, Night Extends the Day: A Clientele Perspective on Equity Premium Variation Abstract: We decompose market returns into their overnight and intraday components, which dramatically improves equity premium forecasts. Past smoothed overnight market returns strongly negatively forecast subsequent close-to-close returns (quarterly R2 of over 14%), primarily through intraday mean reversion. In contrast, past smoothed intraday market returns strongly positively forecast subsequent overnight returns; this partially-offsetting effect explains PE’s relatively poor forecasting ability (R2 only 3%). Our decomposition also resurrects the conditional CAPM: If we allow market betas to vary with past smoothed overnight returns, the four Fama-French factors’ alphas decrease on average by 84%. We interpret these return patterns through a clientele perspective. First, individual investor expectations and consumption growth strongly positively forecast overnight market returns, while intermediary risk tolerance strongly negatively forecasts intraday market returns. Second, aggregate cash-flow news occurs primarily intraday and is positively (negatively) correlated with revisions in expected future overnight (intraday) returns. Finally, while the Tech boom, Covid crash/rebound, and patterns in meme stocks were primarily driven by overnight returns, the Global Financial Crisis was mostly an intraday phenomenon. Event webpage link: https://www.carloalberto.org/event/christopher-polk-london-school-of-econom… Zoom link: https://us02web.zoom.us/j/83709123462pwd=OWpUM0VvRVNzbTN0bUJlRVVsNzA4Zz09 ------------------------------------------------------------------------------------------------------------------------------ May 3rd @ 12.00 Speaker: Andrea Tamoni (Rutgers Business School) Title: Stock Demand and Price Impact of 401(k) Plans Abstract: We estimate a demand system linking 401(k) plans ownership of individual stocks and funds to their demand for equities, and quantify the effect of 401(k) assets on fund managers’ investment behavior. We find that 401(k) fund and stock ownership are the most important variables, after size, explaining fund demand for stocks, with a one standard deviation increase in 401(k) ownership leading to 15-30% increase in stock demand. Funds managing a larger fraction of 401(k) assets tilt their portfolios toward winners, high beta and long duration stocks, outperforming their benchmarks. This investment behavior has important implications for security pricing and generate a feedback effect if pension flows respond positively to relative fund returns. Lastly, we estimate the equilibrium price impact of a change in 401(k) ownership to be positive and increasing over time, consistent with the shift from active to passive investing.

Seminar by Katia Colaneri in Milan (25.01.23)
by Valeria Bignozzi 23 May '23

23 May '23

Dear all, you're invited to the seminar that will take place, in hybrid mode, at the Department of Statistics and Quantitative Methods, University of Milano-Bicocca. More details: • Speaker: Katia Colaneri (email: katia.colaneri(a)uniroma2.it <mailto:katia.colaneri@uniroma2.it>) Title: Some Optimisation Problems in Insurance with a Terminal Distribution Constraint Abstract: In this paper, we study two optimisation settings for an insurance company, under the constraint that the terminal surplus at a deterministic and finite time T follows a normal distribution with a given mean and a given variance. In both cases, the surplus of the insurance company is assumed to follow a Brownian motion with drift. First, we allow the insurance company to pay dividends and seek to maximise the expected discounted dividend payments or to minimise the ruin probability under the terminal distribution constraint. Here, we find explicit expressions for the optimal strategies in both cases, when the dividend strategy is updated at discrete points in time and continuously in time. Second, we let the insurance company buy a reinsurance contract for a pool of insured or a branch of business. We only allow for piecewise constant reinsurance strategies producing a normally distributed terminal surplus, whose mean and variance lead to a given Value at Risk or Expected Shortfall at some confidence level α. We investigate the question which admissible reinsurance strategy produces a smaller ruin probability, if the ruin-checks are due at discrete deterministic points in time. This presentation is based on a joint work with Julia Eisenberg (TU Vienna) and Benedetta Salterini (University of Firenze) Seminar venue: University of Milano-Bicocca Department of Statistics and Quantitative Methods Aula Seminari 4026, 4th floor, Building U7 January 25th, 4:30 pm Webex Link : https://unimib.webex.com/unimib/j.php?MTID=m40cd4bb0d7bb8035ca68f3821f453b33 <https://unimib.webex.com/unimib/j.php?MTID=m40cd4bb0d7bb8035ca68f3821f453b33> Join by meeting number Meeting number (access code): 2743 983 3965 Meeting password: c2uJfPBVe83 (22853728 from phones) Best regards, Valeria

(PMS)^2 talk: J.-D. Deuschel [4 May] at UniMIB
by Maurizia Rossi 03 May '23

03 May '23

Dear colleagues, We are happy to announce the following *hybrid* - that is, in person with online streaming - talk: Speaker: *Jean-Dominique Deuschel* (TU Berlin) *Title: *An isomorphism theorem for Ginzburg-Landau interface models and scaling limits. (See Abstract below.) *Date and Time:* Thursday May 4, 16:30-17:30 (Rome time zone). Place: *Aula 3014, Dip. di Matematica e Applicazioni, Univ. di Milano-Bicocca*, Via R. Cozzi 55, Milano. *Webex link:* https://unimib.webex.com/unimib-it/j.php?MTID=mc07da73e64ea2eb0da78975bc808… *Meeting number:* 2741 491 0178*Password: *HPxNQASR579 (47967277 for phones) %%%%%%%%%% *Abstract: *We introduce a natural measure on bi-infinite random walk trajectories evolving in a time-dependent environment driven by the Langevin dynamics associated with a gradient Gibbs measure with convex potential. We derive an identity relating the occupation times of the Poissonian cloud induced by this measure to the square of the corresponding gradient field, which - generically - is not Gaussian. In the quadratic case, we recover a well-known generalization of the second Ray-Knight theorem. We further determine the scaling limits of the various objects involved in dimension 3, which are seen to exhibit homogenization. In particular, we prove that the renormalized square of the gradient field converges under appropriate rescaling to the Wick-ordered square of a Gaussian free field on R^3 with suitable diffusion matrix, thus extending a celebrated result of Naddaf and Spencer regarding the scaling limit of the field itself. (Based on joint work with Pierre-François Rodriguez.) %%%%%%%%%%% This talk is part of the *(PMS)^2: Pavia-Milano Seminar series on Probability and Mathematical Statistics* organized jointly by the universities Milano-Bicocca, Pavia, Milano-Politecnico. Participation is free and welcome!

De Finetti Risk Seminar - May 3, 2023
by Emanuela Rosazza Gianin 29 Apr '23

29 Apr '23

On behalf of the Scientific Committee of the "B. de Finetti Risk Seminars, Milano Lectures on the Mathematical Theory of Economics and Finance”, we are glad to invite you to participate at the following Lecture: Jean-Pierre Fouque University of California Santa Barbara Title: Reinforcement Learning Algorithm for Mixed Mean Field Control Games Abstract: We present a new combined Mean Field Control Game (MFCG) problem which can be interpreted as a competitive game between collaborating groups and its solution as a Nash equilibrium between the groups. Within each group the players coordinate their strategies. An example of such a situation is a modification of the classical trader's problem. Groups of traders maximize their wealth. They are faced with transaction cost for their own trades and a cost for their own terminal position. In addition they face a cost for the average holding within their group. The asset price is impacted by the trades of all agents. We propose a reinforcement learning algorithm to approximate the solution of such mixed Mean Field Control Game problems. We test the algorithm on benchmark linear-quadratic specifications for which we have analytic solutions. Joint work with A. Angiuli, N. Detering, Mathieu Laurière, and J. Lin.

Seminar Prof. F. Patras at Università degli Studi di Milano
by Stefania Ugolini 28 Apr '23

28 Apr '23

Professor F. Patras (Univ. Côte d’Azur, CNRS) will give a seminar on Thursday, May 04th at 15:00, in Aula Dottorato, at the Department of Mathematics "Federigo Enriques", Università degli Studi di Miano. Title: "Wick polynomials, from classical to free probability." Abstract: Wick polynomials are a central object in quantum physics and classical probability (where they encode for example "chaos decompositions" - they provide an orthonormal basis of the space of square integrable functions of a Gaussian random variable). We will discuss an algebraic formulation of Wick's constructions that allows to generalize them to a wide variety of contexts, featuring free probability - a probability theory closely linked to random matrices but that appears in various recent works, in different areas.

Abstract: In various situations, one may be interested in the concept of differentiation of random variables or processes with respect to some underlying parameters. We will discuss this possibility in the case of random variables related to stopping times. Rather than discussing general theory (which we may), we will present basic examples that give hints about the general results and exhibit the difficulties involved in the development of general results. ________________________________ Fabio Antonelli DISIM - Università di L'Aquila

The C.r.e.d.i.t. 2023 is the*twenty-second *in a series of events dedicated to various aspects of credit risk and organised under the auspices of: the *Department of Economics* and *VERA - Venice centre in Economic and Risk Analytics for public policies - of the Ca’ Foscari University of Venice*, *ABI - Italian Banking Association*,***AIAF - Associazione Italiana per l'Analisi Finanziaria* and *AIFIRM - Associazione Italiana Financial Industry Risk Managers*. Recent years have seen a series of crises (from health/pandemic to climate/energy) that have not only put a strain on global mechanisms previously seen as robust, but have exacerbated existing weaknesses and so increased vulnerability in new crisis situations. The social impact of the pandemic was partially mitigated by public interventions but social conditions then worsened with the soaring costs of energy, raw materials and inflation more broadly. Social and energy costs, which inevitably weigh on invidual countries and aggravate already delicate local situations (e.g., public debts), have led to growing geopolitical tensions, with global systemic consequences. The C.r.e.d.i.t. 2023 conference will be dedicated to Social, Sovereign and Geopolitical Risks to discuss, evaluate and address the near- and medium-term macro-financial impact of persistent crises (“permacrisis”) that can affect the stability of financial as well as socio-economic systems. The organizers encourage submissions on any topic within the overall theme of the conference and in the following areas in particular: * *Socio-economic Stability: *Future development of income (and wealth) inequality and social polarization; Risk, inequality and employment impacts of crises and policies; Gender and skilling issues will increase or help the transition?; * *Sovereign Risks: * Sovereign debt with low economic growth; Long term challenges for fiscal and monetary policies: green transformation, commodity prices, de-globalization and demographic trends; Inflation and exchange rate risks; Environmental and social inter-dependencies; social and environmental preferences and how these affect the stability and macroeconomic wellbeing of a given country; Challenges in measuring the ESG ratings of countries and thus of sovereign debt; * *Geopolitical Risks:* Global supply chain and de-globalization risks for finance; Do international energy price discrepancies pose risks for the competitiveness of EU firms’ and might this have implications for the real exchange rate to?; Risks stemming from accelerating deglobalisation; Cyber-risk vulnerabilities of banks and firms; * *Energy/Commodity Security:* Energy prices and financial performance of firms; Inefficiency of energy markets under scarcity; Transition costs under high energy and resource prices; Volatility of energy-related asset prices (both brown and green) and implications for medium and long term investments in energy production technologies, energy commodity assets and energy infrastructure; Implications of net zero policies for the prices of real estate assets, especially for homeowners and households; * *Long Run Investments and Portfolios:* Stability of asset market equilibria under low returns; Regulation (-demand) driven asset prices; Equilibrium asset price levels under structural transformation and high uncertainty; Net zero pledges and the possible trade-off between sustainability and returns; Engagement versus divesting. The final program will include both submitted and invited papers. Acceptances received so far from invited speakers include *Helen Rey* (London Business School), *Elisa Giuliani *(University of Pisa) and *Moritz Schularick *(Sciences Po Paris & University of Bonn). The Conference will also include panel discussions on the major issues at stake with the views of researchers', practitioners' and policy makers. The SCIENTIFIC COMMITTEE for the Conference consists of: *Moritz Schularick *(Sciences Po Paris & University of Bonn, Programme Chair) *Francesca Campolongo* (Joint Research Center, European Commission) *Rajna Gibson* (University of Geneva & Geneva Finance Research Institute) *Helmut Kraemer-Eis* (European Investment Fund) *Jan Pieter Krahnen *(Leibniz Institute for Financial Research SAFE & Goethe University) *Steven Ongena *(University of Zurich, Swiss Finance Institute, KU Leuven, NTNU Business School & CEPR) *Loriana Pelizzon *(Ca’ Foscari University of Venice, Leibniz Institute for Financial Research SAFE & Goethe University) *Roberto Rigobon* (MIT Sloan School of Management) *Stephen Schaefer *(London Business School) *Marti Subrahmanyam *(NYU Stern Business School) *Christoph Trebesch* (Kiel Institute) CALL FOR PAPERS Those wishing to present a paper at the Conference should submit by *May 31, 2023 *to the address given below (preferably in electronic format).

Corso Paul JENKINS (University of Warwick)
by Matteo Ruggiero 24 Apr '23

24 Apr '23

Cari colleghi, nell’ambito del programma di Visiting Professors della Laurea Magistrale in Stochastics and Data Science dell’Università di Torino (programma completo alla pagina https://www.master-sds.unito.it/go/visiting) con piacere annunciamo il seguente corso: -------------------------------------- Paul JENKINS (University of Warwick) SIMULATION AND INFERENCE IN POPULATION GENETICS Population genetics provides a rich source of data. We now have the ability to sequence, cost-efficiently, the genomes of a large number of individuals from a species. Patterns of variation in DNA sequences offer a rich insight into biological and demographic processes: mutation, natural selection, past migration events, admixture, population structure, and so on. But such data are high-dimensional, noisy, and - because of shared ancestry - not independent, giving rise to some challenging statistical problems. In this course we will cover two important models for the analysis of genetic data - the coalescent, and the Wright-Fisher diffusion. We will discuss methods of simulation of data from these models, as well as how to perform inference for key biological and evolutionary parameters, using techniques such as MCMC. -------------------------------------- Il corso si svolgerà esclusivamente in presenza secondo il seguente calendario: - mar 2 Maggio, h.16-18 - mer 3 Maggio, h.16-18 - ven 5 Maggio, h.11.15-13.15 (Aula 3) - mar 9 Maggio, h.14-16 - mer 10 Maggio, h.16-18 - gio 11 Maggio, h.16-18 - mar 16 Maggio, h.14-16 - mer 17 Maggio, h.16-18 Sede dei corsi: Aula 11 (tranne il 5/5), Terzo piano - Corso Unione Sovietica 218/bis, 10134, Torino. Il corso è rivolto agli studenti della Laurea Magistrale ma la partecipazione è aperta a tutti gli interessati. Cordiali saluti, Matteo Ruggiero --- Matteo Ruggiero University of Torino and Collegio Carlo Alberto www.matteoruggiero.it

Seminario A. Stamm presso Politecnico di Milano
by Laura Maria Sangalli 24 Apr '23

24 Apr '23

Si avvisa che in data 26-04-2023, alle ore 14:30 precise presso il Politecnico di Milano, Dipartimento di Matematica (Edificio 14 - La Nave), in Aula Saleri (sesto piano), nell’ambito delle attività del MOX, si svolgerà il seguente seminario: Aymeric Stamm, Laboratoire de Mathématiques Jean Leray - UMR CNRS, Nantes, France Titolo: Clustering for rotation-valued functional data Abstract: This talk is motivated by the strong case study of monitoring gait for early detection of gait impairment in patients diagnosed with gait-affecting disorders. To this effect, we record the rotation of the hip over time. This leads to data with a great complexity that makes any kind of statistical analysis non-trivial. In effect, we collect functional data that evaluates on the Lie group of three-dimensional rotations which is a non-Euclidean space. In this work, we develop sound statistical methods to enable joint clustering and alignment of such functional data by borrowing ideas from the existing 𝑘-means alignment approach. In the process, we will describe in great length the R package fdacluster, which is an extension of the R package fdakma that provides a fast C++ based implementation of the k-mean alignment algorithm from Sangalli et al. (2010) as well as hierarchical clustering for functional data and tools that help choosing the number of clusters.
