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, “The liquidity uncertainty premium puzzle” by Maria Flora (CREST, ENSAE, Institut Polytechnique de Paris), which will take place on Zoom on May 17, at 12.45. Below you find the Zoom link and an abstract of the presentation.

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. Please forward to anyone interested.

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.

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, “Self Inflicted Debt Crises” by Theo Dimopoulos (HEC Lausanne), which will take place on Zoom on May 12, at 12.00. 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/4a6SaiafujNub6pHriwakj0wncDAbmtUwm…> <#> LTI@Unito and Fondazione Collegio Carlo Alberto are pleased to invite you to the next webinar <#> *May 12, 2021 | 12:00-13:15* *“Self Inflicted Debt Crises”* *Theo Dimopoulos (HEC Lausanne)* <#> *Abstract*: The restrictions on economic activity in the Covid-19 pandemic have led to a looming debt crisis. In a dynamic model of strategic default and debt renegotiation, we show how to resolve debt crises depending on borrowers’ time-inconsistent preferences. 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.
