LTI@Unito Seminars| Dimitri Vayanos (March 7) and Johan Hombert (March 8) @ 12.00
by Luca Regis 17 Mar '23

17 Mar '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): ------------------------------------------------------------------------------------------- March 7th @ 12.00 (webinar) Speaker: Dimitri Vayanos (LSE) Title: Passive Investing and the Rise of Mega-Firms Abstract: We study how passive investing affects asset prices. Flows into passive funds raise dispropor-tionately the stock prices of the economy’s largest firms—even when the indices tracked by the funds include all firms. Passive flows also raise the largest firms’ return volatility the most, andraise the aggregate stock market even when they are entirely due to investors switching from active to passive. These effects arise because of the re-pricing of systematic and large firms’idiosyncratic risk. We estimate that passive investing caused the 50 largest US firms to rise 30%more than the US stock market over 1996–2020.

Using the late 1990s Information and Communication Technology (ICT) boom as a laboratory, we show that skilled labor joining this new sector experienced sizeable long-term earnings losses. We trace these losses to skill obsolescence, that cannot be explained by either selection or the subsequent ICT sector bust. During the boom, capital flowed more to firms whose workers would ultimately experience a larger productivity decline. This suggests that financial capital can amplify the negative effects of labor reallocation into booming sectors on aggregate labor productivity.

40th Linz Seminar on Fuzzy Set Theory: Copulas – Theory and Applications
by Fabrizio, Antonio DURANTE 17 Mar '23

17 Mar '23

Dear Colleague, it is our pleasure to invite you to participate in the 40th Linz Seminar on Fuzzy Set Theory <https://www.flll.jku.at/linz2023> Copulas – Theory and Applications Bildungshaus St. Magdalena, Linz, Austria June 6-9, 2023 Since their inception in 1979 the Linz Seminars on Fuzzy Sets have emphasized the development of mathematical aspects in the context of fuzzy sets by bringing together researchers in fuzzy sets and established mathematicians whose work outside the fuzzy setting can provide direction for further research. The philosophy of the seminar has always been to keep it deliberately small and intimate so that informal critical discussions remain central. LINZ 2023 will be the 40th seminar carrying on this tradition and is devoted to the theme "Copulas — Theory and Applications". The goal of the seminar is to present and to discuss recent advances of copulas and related functions and their applications in pure and applied fields. Accordingly, the topics of the Seminar will include but not be limited to: · Copula theory o From bivariate to multivariate copulas o Dependence measures and association o Approximation and convergence of copulas o Measure theoretic aspects of copulas o Copulas in the discrete setting · Copula applications o Applications in pure and applied fields o Estimation in the context of copulas o Copula methods in Data Science o Feature selection · Relationship to other aggregation functions o Triangular (co)norms, implications o Uninorms, nullnorms o Quasi-copulas, semicopulas o Distribution functions The "Linz" tradition has these key features: the number of participants of the Linz Seminars is usually bounded above by 40 with broad international representation and an enjoyable mix of pure and applied interests; there are no parallel sessions so that all participants focus on each presentation and fully engage in each topic; and there is time for discussion of each presentation, with follow up round table(s) for discussion of open problems and issues raised in the talks. In particular, young researchers (PhD students, junior post-docs) are encouraged to submit their latest results. Please submit your extended abstract (up to 4 pages) by March 29th, 2023 following the guidelines provided at the webpage of the seminar. Further Information about the seminar(s) is available at: https://www.flll.jku.at/linz2023 and https://www.flll.jku.at/linzseminars We look forward to your contributions and to welcoming you in Linz, Best regards, Fabrizio Durante, Susanne Saminger-Platz, Wolfgang Trutschnig (Program Chairs) --------------------------------------------------------- Fabrizio Durante Dipartimento di Scienze dell'Economia Centro Ecotekne Pal.

Deadline *May 2nd, 2023 3pm* (Italian time). *Should you require any assistance with questions that are not addressed in the GSSI website*, please contact applications(a)gssi.it ================================================================== Dear Colleagues, this is to announce the opening for *11 PhD Fellowships* in "Mathematics in Natural, Social and Life Sciences" at Gran Sasso Science Institute (GSSI) starting in November 2021. The application must be submitted through the online form available at www.gssi.it/phd/ by May 2nd, 2023 at 3pm (Italian time zone). Please find the call at https://applications.gssi.it/applications/. The fellowships are awarded for 4 years and their yearly amount is € 16.159,91 gross. All PhD students have free accommodation, free luncheon vouchers and use of the canteen. The official language for the PhD course is English. 1 PhD Fellowship is funded under the ERC project *"CARDIOTRIALS -CARDIac simulations to run in-silicO clinical TRIALS**"*, please find further information below. Within the Ph <https://gssi.it/education/mathematics-education>.D. <https://gssi.it/education/mathematics-education>course in Mathematics in Natural, Social and Life Sciences <https://gssi.it/education/mathematics-education> a priority has been established on mathematical modeling, both towards the traditional areas of application, such as Physics or Engineering, and towards emerging issues in Biology and Social Sciences. GSSI mathematics researchers are interested in tackling many problems with complementary perspectives and methods. The area of Mathematics is characterized by four large macro-sectors: Applied Partial Differential Equations, Stochastic Analysis, Numerical methods and Continuum Mechanics Modeling. Within these sectors there is a shared interest in problems related to fluid dynamics and nonlinear waves, quantum mechanics, statistical mechanics and also its applications to data science. Important ideas of classical analysis, probability theory, mathematical physics and theoretical physics are used also for less traditional applications. Numerical linear algebra and numerical optimization help to design new models and accompanying numerical algorithms for applications in data mining, machine learning and network science. Continuum mechanics models, computational methods in fluid dynamics are used not only in their traditional field at the boundary between applied mathematics and theoretical engineering, but also in nonconventional problems like modeling the full heart function. Students and researchers in Mathematics at GSSI are encouraged to interact with other scientific communities. At GSSI, we believe that the interdisciplinary endeavor is the most effective way to do science and benefit society. Mathematical models are ubiquitous in physics, engineering, information theory, social and life sciences, as they provide a formidable framework to describe the time evolution of deterministic, stochastic and complex systems, which is one of the main goals at GSSI. *1 PhD fellowship* funded under the ERC project *“CARDIOTRIALS -CARDIacsimulations to run in-silicO clinical TRIALS**”*. The project aims at building a virtual model of the human heart based on the fluid-structure-electrophysiology interaction, which will be exploited to study numerically pathologies and assess the efficacy of cardiac devices, accounting for the statistical variability of the population. The project comprises the study of fluid dynamics phenomena and the application of numerical mathematics and high performance computing. The candidates willing to apply are required to work on this specific research project. Within the Ph.D. Programme in Mathematics in Natural, Social and Life Sciences, it is possible to apply both for the CardiOTrials Project position and for GSSI scholarships, by submitting two different applications.

Seminario di Marta Leocata, Martedì 21 Marzo, Sapienza Università di Roma
by Silvestri, Vittoria 16 Mar '23

16 Mar '23

Segnalo il seguente seminario, che si terrà Martedì prossimo in Sapienza. *Martedì 21 Marzo, ore 14:00* Sala di Consiglio, Dipartimento di Matematica, Sapienza Università di Roma *Speaker:* Marta Leocata, SNS *Title: *Modeling an example of green transition *Abstract:* The work presented is part of a collaboration between mathematicians and philosophers of ethics, politics, and society aiming to understand mechanisms of green energy transition where some kind of interaction between many subjects and collective behaviors seem to play a role. We have identified as a first example the case of solar photovoltaic, with the purpose of explaining the time series of Italy and of different regions. We use tools from continuous-time Markov chains, mean field limits, optimal control, and mean field games. Then, we specify our analysis on the case of domestic installations. In order to explain them we propose a Markovian model of interacting particle systems to describe the decision of a significant proportion of the general public in Italy on the installation of solar photovoltaics (PVs) and compare our models to real data. We assume that the adoption decision follows a well precise pattern. First, the general public develops a certain level of sensitivity to climate change and environmental issues. Then it plans to install the PVs because she/he has a sufficient amount of information on the benefits of PVs. Finally, it installs PVs because the economic benefits out-weights the costs. In conclusion, we propose some original policies, not based not on financial incentives. This work is in collaboration with Franco Flandoli (SNS), Giulia Livieri (SNS), Silvia Morlacchi (SNS), Fausto Corvino (University of Gothenburg) and Alberto Pirni (SSSA). ******************************** Vittoria Silvestri Assistant Professor Department of Mathematics University "La Sapienza" Piazzale Aldo Moro, 5 00185 - Rome ********************************

International Conference in Venice - CALL FOR PAPERS
by Monica Billio 16 Mar '23

16 Mar '23

22nd INTERNATIONAL CONFERENCE C.r.e.d.i.t. 2023 *Social, Sovereign and Geopolitical Risks * Venice, Italy 21 –22 September 2023 * * *GRETA Associati* (Venice, Italy), *CRIF* (Bologna, Italy),*European Datawarehouse* (Frankfurt, Germany),*European Investment Bank *(Luxembourg),*European Investment Fund *(Luxembourg) and *Intesa Sanpaolo *(Milan, Italy) are partners in organasing a Conference to be held in Venice on September 21-22, 2023. The C.r.e.d.i.t. 2023 conference will bring together academics, practitioners and PhD students working in various areas of financial and socio-economic risk with the aim of creating a unique opportunity for participants to discuss research progress and policy as well as industry-relevant insights and directions for future research. 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).
