26 May '21

Buongiorno inoltro l'annuncio del OWPS di domani. Saluti Alessandra ---------- Forwarded message --------- Da: One World Probability <ow.probability(a)gmail.com> Date: mer 26 mag 2021 alle ore 08:01 Subject: [owps] Talks thursday May 27 To: <owps(a)lists.bath.ac.uk> Dear All, we have a session on opinion dynamics tomorrow, namely talks by Elchanan Mossel and Timo Vilkas, see below. Remember that we start 14:00 UTC which is 16:00 CET! 14:00-15:00 Elchanan Mossel Opinion Exchange Dynamics I will survey some of the main opinion exchange dynamics models that were invented in probability theory and in economics. I will then discuss ``martingale models" - models where the opinion of each agent forms a martingale. I will highlight some recent large-deviation and graph-limit perspectives of these models. Based on: Mossel, Elchanan, Allan Sly, and Omer Tamuz. "Asymptotic learning on bayesian social networks." Probability Theory and Related Fields 158.1-2 (2014): 127-157. Mossel, Elchanan, Allan Sly, and Omer Tamuz. "Strategic learning and the topology of social networks." Econometrica 83.5 (2015): 1755-1794. Mossel, Elchanan, and Omer Tamuz. "Opinion exchange dynamics." Probability Surveys 14 (2017): 155-204. Harel, Matan, Elchanan Mossel, Philipp Strack, and Omer Tamuz. "Rational groupthink." The Quarterly Journal of Economics 136, no. 1 (2021): 621-668. 15:00 - 16:00 UTC Timo Vilkas Long-term behavior in opinion dynamics: clustering vs. consensus and local vs. global Using the examples of the well-known voter model (Holley & Liggett, 1975) and a lesser-known bounded confidence model. introduced by Deffuant et al. (2000), I want to discuss common limit behavior in interacting particle systems modelling opinion dynamics. Both the transition from clustering to consensus formation and the dichotomy between weak (local) and strong (global) consensus will play a central role. The Zoom link is on the OWPS webpage.

LTI@Unito webinar Andrea Modea (U. Bonn): “Recapitalization, Bailout, and Long-run Welfare in a Dynamic Model of Banking”| May 24, 2021 @12:45
by Luca Regis 20 May '21

20 May '21

Dear Colleagues, I am happy to share with you the following invitation to the Quantative Finance webinar organized by LTI@UniTO and Collegio Carlo Alberto, “Recapitalization, Bailout, and Long-run Welfare in a Dynamic Model of Banking” by Andrea Modena (University of Bonn), which will take place on Zoom on May 24, at 12.45. Below you find the Zoom link and an abstract of the presentation. Best regards, Luca Regis <#> <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/J7QJ4oN6YVj_zZsZOtARrIVf6c7Hmq99bS…> <#> LTI@Unito and Fondazione Collegio Carlo Alberto are pleased to invite you to the following workshop <#> *May 24, 2021 | 12:45 - 13:45* *“Recapitalization, Bailout, and Long-run Welfare in a Dynamic Model of Banking”* *Andrea Modena (University of Bonn, Università Ca’ Foscari Venezia) * <#> *Abstract. *We study the trade-off between the short-run costs and the long-run benefits of bank bailouts. In the model, banks leverage, thanks to their cost advantage at monitoring firms, but hold precautionary capital buffers to avoid costly equity issuance. Banks’ recapitalization is suboptimal because they do not internalize the externalities of the banking sector’s relative size on their individual leverage capacity and firms’ investments. Systematic bailouts can improve the allocation efficiency in bad states, in which banks’ leverage is persistently constrained and investments are low. In the long run, bailouts accelerate the economy’s recovery by fostering growth, thereby reducing endogenous risk. *Zoom link:* *https://us02web.zoom.us/j/83596624662?pwd=ZmlvenJSbGJVZjl4WTA0MnNMUXVlZz09* <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/s-qJVnhbS_zG1dfsi6qOu9mnfTxc8QKO7h…> Meeting ID: 835 9662 4662 Passcode: 056057 <#> <#> <#> <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/yuwpD8sTuPk6FHLiRKKpTMm-UjUyfN6wgb…> <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/VpUegKgodGXzBen7C44jhlkXkF9jhsSmmo…> <#> FONDAZIONE COLLEGIO CARLO ALBERTO Piazza Arbarello 8 - 10122 Torino, Italy phone: +390116705000 segreteria(a)carloalberto.org - www.carloalberto.org Facebook <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/cMWe7pVTdvfxQ1F14Ip-99gRFCuIRpXB8y…> Twitter <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/PBGBAvJh5x5DlI_7sK-JDvUzZNEYzjMddC…> LinkedIn <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/ODY9SQh8giPEbUl9tQNsfhNYuPH1kUrrxH…> Instagram <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/eSYLTqj79odIe23NOKQ9iD17xZiiWLxZpk…> Youtube <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/VHxNOf4LAHpDbLIqIRMcZ1IjxJ8vJMlt0R…> <#> *INFORMATION UNDER THE NEW GENERAL DATA PROTECTION REGULATION (GDPR)* Your personal information has been gathered for the exclusive purpose of informing you about the Collegio's initiatives, considering our and your legitimate interest or your consent.

(PMS)^2 online talk: Alessandra Bianchi, Monday May 24 at 17.30
by Carlo Orrieri 19 May '21

19 May '21

Dear colleagues, We are happy to announce the following online talk: Speaker: Alessandra Bianchi (Università di Padova) Title: Limit Theorems for Exponential Random Graphs. Abstract: Exponential Random Graphs are defined through probabilistic ensembles with one or more adjustable parameters. They can be seen as a generalization of the classical Erdos Renyi random graph, obtained by defining a tilted probability measure that is proportional to the densities of certain given finite subgraphs. In this talk we will focus on the edge-triangle model, that is a two-parameter family of exponential random graphs in which dependence between edges is introduced through triangles. Borrowing tools from statistical mechanics, together with large deviations techniques, we will characterize the limiting behavior of the edge density for all parameters in the so-called replica symmetric regime, where a complete characterization of the phase diagram of the model is accessible. First, we determine the asymptotic distribution of this quantity, as the graph size tends to infinity, in the various phases. Then we study the fluctuations of the edge density around its average value off the critical curve and formulate conjectures about the behavior at criticality based on the analysis of a mean-field approximation of the model. Joint work with Francesca Collet and Elena Magnanini. Date and time: Monday May 24, 17:30-18:30 (Rome time zone) Zoom link: https://us02web.zoom.us/j/81602205122?pwd=Wlk0SVZPRjY4UHFzR1c5RmJMekRCZz09 <https://us02web.zoom.us/j/81602205122?pwd=Wlk0SVZPRjY4UHFzR1c5RmJMekRCZz09> Meeting ID: 816 0220 5122 Passcode: d5v0SS This talk is the second of the (PMS)^2: Pavia-Milano Seminar series on Probability and Mathematical Statistics organized jointly by the universities Milano-Bicocca, Pavia, Milano-Politecnico and Milano-Statale. Participation is free and welcome! (though limited to 100 participants for technical reasons) Best regards The organizers (Mario Maurelli, Carlo Orrieri, Maurizia Rossi, Margherita Zanella)
