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)

WEBINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.carloalberto.org/events/category/seminars/seminars-in-statistic…> Venerdi 21 Maggio 2021, alle ore 12.00, si terrà il seguente webinar: ------------------------------------------------ Speaker: *Paul Jenkins *(University of Warwick) Title: *Asymptotic genealogies of interacting particle systems* Join Zoom Meeting https://us02web.zoom.us/j/87319216872?pwd=L1JnR0UvamZ2RC9Eb2xFbW9qREN0Zz09 Meeting ID: 873 1921 6872 Passcode: 626226 Abstract: Interacting particle systems are a broad class of stochastic models for phenomena arising in physics, engineering, biology, and finance. A prominent class of such models can be expressed as a sequential Monte Carlo algorithm in which the aim is to construct an empirical approximation to a sequence of measures. The approximation is constructed by evolving a discrete-time, weighted population of particles, alternating between a Markov update and a resampling step. Resampling gives rise to a notion of a genealogy in which duplicated particles are regarded as offspring of their parents. In this talk I discuss how to characterise the genealogy underlying this evolving particle system. More precisely, under certain conditions we can show that the genealogy converges (as the number of particles grows) to Kingman's coalescent, a stochastic tree-valued process widely studied in population genetics. This makes explicit the analogy between sequential Monte Carlo and an evolving biological population. This is joint work with Suzie Brown, Adam Johansen, Jere Koskela, and Dario Spanò. ------------------------------------------------ Il webinar è organizzato dalla "de Castro" Statistics Initiative www.carloalberto.org/stats Cordiali saluti, Pierpaolo De Blasi --- University of Torino & Collegio Carlo Alberto carloalberto.org/pdeblasi <https://sites.google.com/a/carloalberto.org/pdeblasi/>

We show that the alleged negative relation is not robust to the aggregation window, nor to the way the volatility of volume is measured. In particular, when we employ high-frequency one-minute volume data, the relation is positive and robust, restoring economic intuition which commends investors’ aversion to liquidity uncertainty. *Zoom link*: https://us02web.zoom.us/j/81109847151?pwd=TEl0L1lNVEtUbjh5RVJvM3pRUG40UT09 <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/hB0bS22L3Y_ENjUYgp7T2q29i3-4-1d8K-…> Meeting ID: 811 0984 7151 Passcode: 268588 <#> <#> <#> <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/UOaR7QZZ72ijC7nTqdjimVg5pfXen_62Nr…> <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/xNe5dk_6XysCdtcFZgp9tEdEOiDcNPaSPo…> <#> 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/aYJaD7KHzPThdS0ChTziuoKxUUel5iGJkU…> Twitter <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/vhWcXWrVH_v7eAq6F84bbGMelwvSuUQT3Q…> LinkedIn <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/dfKa9OGMdhR4lMt-qQMtDhs0uMVON6_UUF…> Instagram <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/FZi5lYdgx-IrtBPfZ_N1VOEbhUdSAHDONW…> Youtube <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/LsxVbQ7peor6-eKyVmNsaiIImZcs_kIZ2U…> <#> *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.

virtual seminar in Insubria & Bicocca
by Emanuela Rosazza Gianin 12 May '21

12 May '21

Dear all, On *May 20 at 17:00, Cosimo-Andrea Munari* (University of Zurich) will give a virtual seminar “in Insubria & Bicocca”, to which you are all invited. You can find the title and abstract below. Title: Capital requirements and claims recovery: A new perspective on solvency regulation Abstract: Protection of creditors is a key objective of financial regulation. Where the protection needs are high, i.e., in banking and insurance, regulatory solvency requirements help prevent creditors from incurring losses on their claims. The current regulatory requirements based on Value at Risk and Expected Shortfall limit the probability of default of financial institutions, but fail to control the size of recovery on creditors' claims in the case of default. We resolve this failure by developing a novel risk measure, Recovery Value at Risk. Our conceptual approach is flexible and allows the construction of general recovery risk measures. By design, these risk measures control recovery on creditors' claims and integrate the protection needs of creditors into the incentive structure of the management. The seminar will be on *Zoom*. You can find the information to join below. Speaker: Cosimo-Andrea Munari (Univ. Zurich) Topic: Capital requirements and claims recovery: A new perspective on solvency regulation Time: May 20, 2021 05:00 PM Rome Where: Zoom Link: https://us02web.zoom.us/j/82132902292?pwd=UlJXcE5mT1dmSmhtKzNkS1pXTlRhUT09 ID riunione: 821 3290 2292 Passcode: 912323 After the talk, you are all invited to remain in the meeting for an informal aperitif and chat.

Online Seminar @SNS, Julien Guyon (Bloomberg L.P.), May 18 2021 at 4 PM (CEST)
by Giulia Livieri 12 May '21

12 May '21

Dear all, Tuesday, May 18 at 4 PM (CEST) there will be the following online seminar. Speaker: Julien Guyon (Bloomberg L.P.); below the short bio. Title: Dispersion-Constrained Martingale Schrodinger Problems and the Joint S&P 500/VIX Smile Calibration Puzzle Abstract: The very high liquidity of S&P 500 (SPX) and VIX derivatives requires that financial institutions price, hedge, and risk-manage their SPX and VIX options portfolios using models that perfectly fit market prices of both SPX and VIX futures and options, jointly. This is known to be a very difficult problem. Since VIX options started trading in 2006, many practitioners and researchers have tried to build such a model. So far the best attempts, which used parametric continuous-time jump-diffusion models on the SPX, could only produce approximate fits. In this talk we solve this long standing puzzle for the first time using a completely different approach: a nonparametric discrete-time model. Given a VIX future maturity T1, we build a joint probability measure on the SPX at T1, the VIX at T1, and the SPX at T2 = T1 + 30 days which is perfectly calibrated to the SPX smiles at T1 and T2, and the VIX future and VIX smile at T1. Our model satisfies the martingality constraint on the SPX as well as the requirement that the VIX at T1 is the implied volatility of the 30-day log-contract on the SPX. The model is cast as the unique solution of what we call a Dispersion-Constrained Martingale Schrodinger Problem which is solved by duality using an extension of the Sinkhorn algorithm, in the spirit of (De March and Henry-Labordere, Building arbitrage-free implied volatility: Sinkhorn's algorithm and variants, 2019). We prove that the existence of such a model means that the SPX and VIX markets are jointly arbitrage-free. The algorithm identifies joint SPX/VIX arbitrages should they arise. Our numerical experiments show that the algorithm performs very well in both low and high volatility environments. Finally, we discuss how our technique extends to continuous-time stochastic volatility models, via what we dub VIX-Constrained Martingale Schrodinger Bridges, inspired by the classical Schrodinger bridge of statistical mechanics. The resulting stochastic volatility model is numerically implemented and is shown to achieve joint calibration with very high accuracy. Time permitting, we will also briefly discuss a few related topics: (i) a remarkable feature of the SPX and VIX markets: the inversion of convex ordering, and how classical stochastic volatility models can reproduce it; (ii) why, due to this inversion of convex ordering, and contrary to what has often been stated, among the continuous stochastic volatility models calibrated to the market smile, the local volatility model does not maximize the price of VIX futures. Short bio: Julien Guyon is a senior quantitative analyst in the Quantitative Research group at Bloomberg L.P., New York. He is also an adjunct professor in the Department of Mathematics at Columbia University and at the Courant Institute of Mathematical Sciences, NYU, and a Louis Bachelier Fellow. Julien serves as an Associate Editor of SIAM Journal on Financial Mathematics, Finance & Stochastics, and Journal of Dynamics and Games, and as a Managing Editor of Quantitative Finance. Before joining Bloomberg, Julien worked in the Global Markets Quantitative Research team at Societe Generale in Paris for six years, and was an adjunct professor at Universite Paris Diderot and Ecole des Ponts ParisTech. Julien co-authored the book Nonlinear Option Pricing (Chapman & Hall, 2014) with Pierre Henry-Labordere. He has published more than 20 articles in peer-reviewed journals (including Finance & Stochastics, SIAM Journal on Financial Mathematics, Quantitative Finance, Risk, Journal of Computational Finance, Annals of Applied Probability, Stochastic Processes and their Applications) and is a regular speaker at international conferences, both academic and professional. His main research interests include nonlinear option pricing, volatility and correlation modeling, (nonlinear) optimal transport, and numerical probabilistic methods. A big soccer fan, Julien has also developed a strong interest in sports analytics, and has published several articles on the FIFA World Cup, the UEFA Champions League, and the UEFA Euro both in academic journals and in top-tier newspapers such as The New York Times, The Times, Le Monde, and El Pais, including a new, fairer draw method for the FIFA World Cup. Some of his suggestions for draws and competition formats have already been adopted by FIFA and UEFA. His paper "Risk of collusion: Will groups of 3 ruin the FIFA World Cup?" won the 2nd prize at the 2021 MIT Sloan Sports Analytics Conference, the biggest sports analytics event in the world.

Myopic borrowers misprice their option to default by a U-shaped negative pricing error, which causes imperfect consumption smoothing, underinvestment in normal times, and risk shifting in crisis times. The model shows that bailouts need to be tailored to borrowers’ myopia, that lenders and borrowers ultimately self-inflict debt crises through their strategic interaction, that myopic distress can be cheaper to resolve than rational distress, and that myopia can be beneficial for rational agents. Optimal bailouts either punish or reward myopia through smaller or larger transfers, leading to procrastinated default and protracted crises or the reverse, depending on whether transfers exacerbate or alleviate the borrowers’ misperception of default risk. *Zoom Link*: https://us02web.zoom.us/j/86981911369?pwd=enM0c0lRM1BqOUhiNXJ1b1hoRUFkZz09 <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/hbrUdAY_KcHiYFp-zoUEFWWBp9T0Kg0cUl…> Meeting ID: 869 8191 1369 Passcode: 166986 <#> <#> <#> <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/Kc1f2ufQnOOWcPREh0lKmL7Q4fzC6kZTEu…> <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/b-edRrCQzu0enNR_azA3LGWp3pL_izmv84…> <#> 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/Gt2401hi4FK-WGDLZAuu96sNqvjzd4A07j…> Twitter <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/dMAP2G9V5OGEVQgiZTVGvRpJC3GmNfL6Kc…> LinkedIn <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/ZfldktwuWczKYK5tZjUQN--QuFGPkzyS3J…> Instagram <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/lxHhxw7_pN8bfa4lRN1Ro0KNXDKFYNSqGI…> Youtube <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/toZ5omiJqAM-e_mmWMFepsHZKCAJ2-Skq2…> <#> *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.

Pisa Online Seminars - Michael Högele and Alessandra Caraceni (Tuesday, May 11 at 16:00 and 17:00)
by Giacomo Filippo Di Gesu 06 May '21

06 May '21

Dear colleagues, I would like to invite you to the following online seminar organized by the Probability group of the University of Pisa. The two talks will be accessible under the link Click here to join<https://teams.microsoft.com/l/meetup-join/19:af3d635091e049579e555a84219ab3…"Tid":"c7456b31-a220-47f5-be52-473828670aa1","Oid":"dfd1e5f6-331d-43e0-a180-4bb6ce727fb7"}> Best regards, Giacomo Tuesday, May 11, 16:00 Speaker: Michael Högele (Universidad de los Andes) Title: Cutoff thermalization for Ornstein-Uhlenbeck systems with small Lévy noise in the Wasserstein distance Abstract: This talk presents recent results on cutoff thermalization (also known as the cutoff phenomenon) for a general class of asymptotically exponentially stable Ornstein-Uhlenbeck systems under ε-small additive Lévy noise. The driving noise processes include Brownian motion, α-stable Lévy flights, finite intensity compound Poisson processes and red noises and may be highly degenerate. Window cutoff thermalization is shown under generic mild assumptions, that is, we see an asymptotically sharp ∞/0-collapse of the renormalized Wasserstein distance from the current state to the equilibrium measure μ^ε along a time window centered in a precise ε-dependent time scale t_ε . In many interesting situations such as reversible (Lévy) diffusions it is possible to prove the existence of an explicit, universal, deterministic cutoff thermalization profile. The existence of this limit is characterized by the absence of non-normal growth patterns in terms of an orthogonality condition on a computable family of generalized eigenvectors of the matrix Q. With this piece of theory at hand this article provides a complete discussion of the cutoff phenomenon for the classical linear oscillator with friction subject to ε-small Brownian motion or α-stable Lévy flights. Furthermore, we cover the highly degenerate case of a linear chain of oscillators in a generalized heat bath at low temperature. Tuesday, May 11, 17:00 Speaker: Alessandra Caraceni (University of Oxford) Title: Polynomial mixing time for edge flips on planar maps Abstract: A long-standing problem proposed by David Aldous consists in giving a sharp upper bound for the mixing time of the so-called “triangulation walk”, a Markov chain defined on the set of all possible triangulations of the regular n-gon. A single step of the chain consists in performing a random edge flip, i.e. in choosing an (internal) edge of the triangulation uniformly at random and, with probability 1/2, replacing it with the other diagonal of the quadrilateral formed by the two triangles adjacent to the edge in question (with probability 1/2, the triangulation is left unchanged). While it has been shown that the relaxation time for the triangulation walk is polynomial in n and bounded below by a multiple of n^{3/2}, the conjectured sharpness of the lower bound remains firmly out of reach in spite of the apparent simplicity of the chain. For edge flip chains on different models – such as planar maps, quadrangulations of the sphere, lattice triangulations and other geometric graphs – even less is known. We shall discuss results concerning the mixing time of random edge flips on rooted quadrangulations of the sphere obtained in joint work with Alexandre Stauffer. A “growth scheme” for quadrangulations, which generates a uniform quadrangulation of the sphere by adding faces one at a time at appropriate random locations, can be combined with careful combinatorial constructions to build probabilistic canonical paths in a relatively novel way. This method has implications for a range of interesting edge-manipulating Markov chains on so-called Catalan structures, from “leaf translations” on plane trees to “edge rotations” on general planar maps. ************************ Giacomo Di Gesù Dipartimento di Matematica Università di Pisa Largo Bruno Pontecorvo 5 56127 - Pisa, Italy giacomo.digesu(a)unipi.it<mailto:giacomo.digesu@unipi.it> https://sites.google.com/site/giacomodigesu/

Seminar Aernout van Enter
by Massimo Campanino 05 May '21

05 May '21

Aernout van Enter ONE-SIDED VERSUS TWO-SIDED STOCHASTIC PROCESSES Thursday the 6th of May 3 pm (Italian time) Stochastic processes can be parametrised by time (such as occurs in Markov chains), in which case conditioning is one-sided (on the past) or by one-dimensional space (which is the case, for example, for one-dimensional Markov fields), where conditioning is two-sided (on the right and on the left). I will discuss some examples, in particular generalising this distinction to g-measures versus Gibbs measures, where, instead of a Markovian dependence, the weaker property of continuity (in the product topology) is considered. In particular I will discuss when the two descriptions (one-sided or two-sided) produce the same objects and when they are different. We show moreover the role one-dimensional entropic repulsion plays in this setting. Based on joint work with R. Bissacot, E. Endo and A. Le Ny, and S.

Fwd: [owps] OWPS: talks tomorrow
by Faggionato, Alessandra 05 May '21

05 May '21

Buongiorno giro l'annuncio del OWPS di domani. Saluti Alessandra ---------- Forwarded message --------- Da: One World Probability <ow.probability(a)gmail.com> Date: mer 5 mag 2021 alle ore 08:12 Subject: [owps] OWPS: talks tomorrow To: <owps(a)lists.bath.ac.uk> Dear All, we have two talks tomorrow. Remember that we start 14:00 UTC which is 16:00 CET! 14:00-15:00 UTC Christina Goldschmidt The stable graph: the scaling limit of critical random graphs with i.i.d. random degrees having power-law tails Abstract: Consider a graph with label set \{1,2, \ldots,n\} chosen uniformly at random from those such that vertex i has degree D_i, where D_1, D_2, \ldots, D_n are i.i.d. strictly positive random variables. The condition for criticality (i.e. the threshold for the emergence of a giant component) in this setting is E[D^2] = 2 E[D], and we assume additionally that P(D = k) \sim c k^{-(\alpha + 2)} as k tends to infinity, for some \alpha \in (1,2). In this situation, it turns out that the largest components have sizes on the order of n^{\alpha/(\alpha+1)}. Building on earlier work of Adrien Joseph, we show that the components have scaling limits which can be related to a forest of stable trees (à la Duquesne-Le Gall-Le Jan) via an absolute continuity relation. This gives a natural generalisation of the scaling limit for the Erd\H{o}s-Renyi random graph (obtained in collaboration with Louigi Addario-Berry and Nicolas Broutin a few years ago, extending results of Aldous), which we call the stable graph. This complements recent work on random graph scaling limits by various authors including Bhamidi, Broutin, Duquesne, van der Hofstad, van Leeuwaarden, Riordan, Sen, M. Wang and X. Wang. 15:00 - 16:00 UTC Bénédicte Haas Distributional properties of the stable graphs Abstract: In this talk we will investigate some distributional properties of the connected components of the stable graphs introduced by Christina in the previous talk. We recall that for $\alpha \in (1,2]$, the $\alpha$-stable graph arises as the universal scaling limit of critical random graphs with i.i.d. degrees having an $\alpha$-dependent power-law tail behavior. Consider a connected component of such a graph. Our aim will be: (1) to describe the distribution of its kernel and more generally of its discrete finite-dimensional marginals, (2) to explicit its distribution as a collection of $\alpha$-stable trees glued on the kernel, and (3) present a line-breaking construction, in the same spirit as Aldous’ line-breaking construction of the Brownian CRT.

International Conference in Venice - CALL FOR PAPERS
by Monica Billio 04 May '21

04 May '21

20th INTERNATIONAL CONFERENCE CREDIT 2021 *Compound Risk: Climate, Disaster, Finance, Pandemic * Venice, Italy 23 –24 September 2021 * * *GRETA Associati* (Venice, Italy), *Cattolica Assicurazioni* (Verona, Italy), *European Datawarehouse *(Frankfurt, Germany), *European Investment Bank* (Luxembourg), *European Investment Fund *(Luxembourg) and *Intesa Sanpaolo *(Milan, Italy) are co-sponsors of a Conference to be held in Venice on September 23-24, 2021. The Conference CREDIT 2021 will bring together academics, practitioners and PhD students working in various areas of financial and credit risk with the aim to create a unique opportunity for participants to discuss research progress and policy and industry-relevant insights as well as directions for future research. Credit 2021 is the *twentieth *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 the *Joint Research Center, European Commission* (Ispra, Italy). The theme of this year’s conference is the relation between financial risk on the one hand and pandemic, climate and disaster risk, on the other hand, with particular attention to the possible compounding of different sources of risk. The past year, 2020, has been marked by the still-ongoing COVID-19 pandemic crisis, which has shown how fragile our economic systems can be when confronted with shocks that threaten public health and the closeness of the connections between economic and financial risks and public policy. Climate change is now widely recognized as a new source of financial risk which is relevant both at the level of households and individual institutions and the systemic level. In particular, the many central banks and financial institutions that have joined the Network for Greening the Financial System (NGFS) have issued recommendations on how to integrate climate considerations into risk management strategies and practices. However, risks such as pandemics and climate change do not occur in isolation but can also compound, as has already been seen in several countries. The compounding of risk, which is currently poorly understood, increases the complexity of risk assessment and risk management, and it has implications for socio-economic development, as well as for public debt sustainability. In the EU, these aspects have major implications for efforts to increase the resilience of the economy to future shocks and to “build back better”, and requires the alignment of COVID-19 recovery policies, such as those supported by the NextGenerationEU, and the EU Green Deal and the Paris Agreement targets. The organizers of CREDIT 2021 encourage submissions on a range of topics of relevance to this year’s theme including: finance and COVID-19; finance and climate risks; finance and compound COVID-19 and climate risks. In particular, submissions are welcome in the following areas: • INVESTMENTS: Sustainable Finance, Disaster risk finance; Finance 4 good; public finance; blended finance. • POLICIES: Climate Policies, European Green New Deal; Next Generation EU; Recovery Plan. • INFORMATION: Data gaps; modelling challenges; risk transmission channels; uncertainty; complexity. The final program will include both submitted and invited papers. Acceptances received so far from invited speakers include *Vittoria Colizza *(INSERM, France), *Robert Engle *(Stern Business School, New York University) and *Roberto Rigobon* (MIT Sloan School of Management) who will deliver keynotes, respectively on finance and on epidemics. The Conference will also feature panel discussions on researchers', practitioners' and policy makers’ views of the major issues at stake. The SCIENTIFIC COMMITTEE for the Conference consists of: • * Stefano Battiston *(Ca’ Foscari University of Venice & University of Zurich, Programme Chair) • * Monica Billio *(Ca’ Foscari University of Venice & GRETA) • * Francesca Campolongo *(Joint Research Center, European Commission) • *Vittoria Colizza* (INSERM, France) • * Helmut Kraemer-Eis* (European Investment Fund) • * Jan Pieter Krahnen* (Leibniz Institute for Financial Research SAFE & Goethe University, Frankfurt) • *Irene Monasterolo *(Vienna University of Economics and Business) • *Steven Ongena* (University of Zurich, Swiss Finance Institute, KU Leuven & CEPR) • *Roberto Rigobon* (MIT Sloan School of Management) • *Stephen Schaefer* (London Business School) CALL FOR PAPERS Those wishing to present a paper at the Conference should submit by *May 31, 2021 *to the address given below (preferably in electronic format). Please indicate to whom correspondence should be addressed. Decisions regarding acceptance will be made by *June 30, 2021*. The final version of accepted papers must be received by August 31, 2021.

(PMS)^2 online talk: Guangqu Zheng, Monday May 10 at 17:30
by Maurizia Rossi 03 May '21

03 May '21

Dear colleagues, We are happy to announce the following online talk: Speaker: *Guangqu Zheng* (University of Kansas) Title: *Malliavin derivatives of hyperbolic Anderson model with applications to its absolute continuity and spatial averages.* Date and time: *Monday May 10, 17:30-18:30 (Rome time zone)* Abstract: see below. Zoom link: https://us02web.zoom.us/j/83843864962?pwd=NlNadHhIRkdzYUErZWJpbTNJaytDUT09 Meeting ID: 838 4386 4962 Passcode: 5gVVXb 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) *Abstract:* In this talk, we present recent work on the hyperbolic Anderson model driven by a space-time colored Gaussian homogeneous noise with spatial dimension one and two. Under mild assumptions, we provide Lp-estimates of the iterated Malliavin derivatives of the solution in terms of the fundamental solution of the wave solution. We present two applications: (1) We present quantitative central limit theorems for spatial averages of the solution to the hyperbolic Anderson model, where the rates of convergence are described by the total variation distance. These quantitative results have been elusive so far due to the temporal correlation of the noise blocking us from using the Itô calculus. (2) We establish the absolute continuity of the law for the hyperbolic Anderson model. The Lp-estimates of Malliavin derivatives are crucial ingredients to verify a local version of Bouleau-Hirsch criterion for absolute continuity. Our approach substantially simplifies the arguments for the one-dimensional case, which has been studied in the recent work by Balan, Quer-Sardanyons and Song (2019). This talk is based on the joint work (arXiv:2101.10957) with *R. Balan*, *D. Nualart* and *L. Quer-Sardanyons* (2021). - - - Maurizia Rossi Dipartimento di Matematica e Applicazioni Università di Milano-Bicocca

Seminar Antonio Linero @Bocconi - May 6th
by Giacomo Zanella 03 May '21

03 May '21

We announce the following DEC Statistics webinar at Bocconi: Date: Thursday, May 6, h17:00 (Italy time) Speaker: Antonio Linero (UT Austin) Title: Bayesian Decision Tree Ensembling Strategies for Nonparametric Problems Abstract: In this talk we will make the case for using Bayesian decision tree ensembles, such as Bayesian additive regression trees (BART), for addressing some fully-nonparametric problems. We present models for density regression and survival analysis, and argue that our approaches are both easier to use and more effective than more standard Bayesian nonparametric solutions (such as those based on mixture models). On the applied side, we show how to use our models to extract interesting features across several datasets. On the theoretical side, we also show that our models attain minimax-optimal rates of convergence of the posterior in high-dimensional settings. Throughout the talk, we will emphasize the flexibility and ease-of-use of our approach: all simulation and real data analyses attain excellent results using heuristically chosen "default" priors, and it is quite straight-forward for researchers (both in-principle and in-practice) to embed our ensembles in larger models. The webinar will be on zoom at: https://zoom.us/j/95265599865?pwd=NlEwVWFjNktjNkx5VjZFZmFLVGh0UT09 Meeting ID: 952 6559 9865 Passcode: 634366 Kind regards, Giacomo Zanella
