Three lectures on Algorithmic Game Theory
by Marco Scarsini 23 May '19

23 May '19

Professor Georgios Piliouras (Singapore University of Technology and Design) will give the following three lectures on "Frontiers in Algorithmic Game Theory" LUISS Viale Romania 32 00197 Roma Room 303 Monday May 27th, 2019, h16:00-17:30 Blockchain and Cryptocurrencies Cryptocurrencies have shown to be reliable payment platforms and gathered immense interest in recent years. At their core, though, cryptocurrencies are simply decentralized ledgers: a network of participants who agree upon protocol rules that describe how the ledger can be update and maintain consensus among all participants. Even if no individual participant in the network can be trusted, a combination of cryptography and game-theoretic incentives ensures that the network as a whole is reliable and can be trusted. The aim of the tutorial is to provide an introduction to cryptocurrencies, outlining their structure and design with a focus on the game theoretic elements. Tuesday May 28th, 2019, h11:00-12:30 Markets as Pendulums: The Physics of Learning in Games We review a recent thread of papers that explores connections between adaptive learning dynamics in games and ideas in classical mechanics: E.g. When can we prove that learning behavior in a game is periodic? Is there a notion of energy that is being preserved? What are the laws of motion for markets? We will bring together notions from physics such as Poincaré recurrence, Hamiltonians and energy conservation with standard game theoretic notions of Nash and coarse correlated equilibria. No background in physics is expected and the talk will be self-contained. Wednesday May 29th, 2019, h11:00-12:30 Onset of Chaos in Traffic Routing (and Beyond) We study both theoretically and experimentally a standard theoretical benchmark of game theory, non-atomic routing games. Several learning dynamics are classically known to equilibrate in this setting due to its connection to convex optimization. Nevertheless, as we will show if we keep upping the total demand in these systems, then they go through phase transitions and become formally chaotic. We provide both theoretical and experimental evidence about the robustness of this phenomenon. A new vocabulary emerges to describe this behavior, such as formal definitions of chaos. We will examine this new terminology and give several examples to make these notions more intuitive. Finally, we will also uncover new regularities in these chaotic systems. What type of order is hidden within chaos? ******************************************************* Marco Scarsini Dipartimento di Economia e Finanza Luiss Viale Romania 32 00197 Roma, ITALY URL: http://docenti.luiss.it/scarsini/

REMINDER - International Conference in Venice - CALL FOR PAPERS
by Monica Billio 22 May '19

22 May '19

CREDIT2019 <http://www.greta.it/credit/credit2019/credit2019.htm> *GRETA Associati* (Venice, Italy), *European DataWarehouse* (Frankfurt am Main, Germany), *Intesa Sanpaolo* (Milan, Italy) and *S&P Global Market Intelligence* (London, UK) are co-sponsors of a Conference to be held in Venice on September 26-27, 2019. The objective of the Conference is to bring together academics, practitioners and Ph.D. students working in the area of risk management. The conference will provide an opportunity for participants engaged in research at the forefront of this area to discuss both the causes and implications of recent financial and atmospheric events and may, in turn, suggest fruitful directions for future research. The Conference, organised under the auspices of the *Department of Economics of the University Ca’ Foscari of Venice*, *ABI - Italian Banking Association*, *AIAF - Associazione Italiana per l'Analisi Finanziaria* (Milan, Italy) and the *Joint Research Center, European Commission* (Ispra, Italy), is the *eighteenth *of a series dedicated to various aspects of credit risk. //The adoption of the Paris Agreement on climate change and the UN 2030 Agenda for Sustainable Development marks a historical international commitment to the objective of a more sustainable economy and society. How to mobilise the necessary financing for green and sustainable investments is thus a primary need. // //Meanwhile, Regulators are discussing about a green-supporting or a brown-penalising factor since they want to make sure financial institutions are prepared. It is to find the way to support sustainable investments but it is primarily a discussion about credit risk.// //The banking and insurance industries and more in general the financial sector has to develop new asset management strategies and to adjust their credit allocation practices to cope with these new challenges and take advantage of the new opportunities. All these changes call for a substantial amount of research to improve the knowledge of the mechanisms at play and to design adapted policy tools. ////////// The organizers encourage submissions of papers on any topic within the overall theme of the conference and in the following areas in particular: * Analysis of climate change effects on companies’ creditworthiness, in terms of risk exposure and possible loss of business continuity; understanding on how to integrate the environmental risk and opportunities of banks’ or insurers’ counterparties in the credit process * Development of metrics for climate-related financial risks and investments opportunities; definition of an EU environmental and climate change (ECC) risk categorising system by economic sectors/sub-sectors for ECC screening to provide a sound and reliable basis for setting high-level policies for credit protection and allocation * Analysis of the climate change impact on the insurance sector and on the development of non-life and reinsurance products for the corporate and retail segments Analysis of climate-aligned developments in the financial markets (e.g. green bonds) and opportunities for financial institutions in fostering the low-carbon transition * Transmission channels of climate-related shocks from the real economy to financial institutions’ portfolios and amplification mechanisms of climate-related shocks through credit chains * Assessment of the potential impact of green financial policies, including climate-aligned monetary policies and macroprudential regulation * Big data and artificial intelligence to assess and manage the corporate exposures to climate change factors. The final program will include both submitted and invited papers. Acceptances received so far from invited speakers include *Robert Engle *(New York University, Stern Business School), *Andreas Hoepner* (University College Dublin), *Irene Monasterolo* (Wirtschaftsuniversität Wien, Vienna) and *Til Schuermann *(Oliver Wyman, New York). The Conference will also feature a panel discussion on researchers', practitioners' and policy makers’ views of the major outstanding problems.

seminario probabilità statistica matematica sapienza
by Piccioni, Mauro 22 May '19

22 May '19

Il 28 maggio alle ore 14 in Aula di Consiglio del Dipartimento di Matematica, Sapienza Università di Roma di terrà il seguente seminario di Probabilità e Statistica Matematica: GERARD LETAC, IMT, Université Paul Sabatier, Toulouse, France MULTIVARIATE RECIPROCAL INVERSE GAUSSIAN DISTRIBUTIONS: THE SURPRISING INTEGRALS OF SUPERSYMMETRY Abstract If $W=(w_{ij})_{1\leq i,j\leq n}\)$ is a symmetric matrix with $w_{ij}\geq 0$ and zero diagonal, consider the matrix $M_x=2\mathrm{diag}(x_1,\ldots,x_n)-W$ and the set $C_W$ of $x\in \mathbb{R}^n$ such that $M_x$ is positive definite. Physicists and probabilists have considered in the last ten years several integrals equivalent to $\int_{C_W}\exp(-a^*M_xa-b^*M_x^{-1}b)(\det M_x)^{q-1}dx$. According to the properties of the undirected graph $G$ associated to $W$ with vertices $1,\ldots,n$ and edges $(i,j)$ such that $w_{ij}\neq 0$, we compute some of these integrals and we study the corresponding exponential families on $\mathbb{R}^n$ with many attractive properties.

Final call "YUIMA Summer School". Free admission for students. Brixen (IT) 25-28 June 2019. Registration extended.
by stefano iacus 22 May '19

22 May '19

The first YUIMA Summer School on Computational and Statistical Methods for Stochastic Process & Third Yuima Workshop* This 4 days course aims at introducing researchers, PhD students and practitioners to several aspects of modern numerical and statistical analysis of time series through the R language and, in particular, the YUIMA package. The course covers topics of R programming, time series data handling, simulation and numerical analysis for several types of statistical models including: point processes, Hawkes processes,stochastic differential equations driven by Brownian motion with or without jumps, fractional Brownian motionand Lévy processes. *Program to be announced, by invitation only Who can benefit? Stochastic differential equations, with or without jumps, are nowadays used as statistical models in many contexts, including but not limited to, finance, insurance, phylogenetics, genomics, political analysis, economics,migration flow analysis,social network analysis, and more. They are continuous-time models fitted on discrete sampled data. Point processes, like Compound Poisson and Hawkes processes are used in Limit Order Book (LOB) analysis in trading and finance, as well as in the analysis of rainfalls in meteorology or in earthquakes analysis in seismology. Jump and Lèvy processes extends many of the above models to a variety of statistical distributions that are able to capture stylised facts about real time series. Last, but not least, fractional processes are typical tools of climate change studies. Although the course could not cover all of the above applications, the participants can benefit from understanding the simulation and estimation techniques for these classes of stochastic process and apply to their own research field with the help of the faculties of this summer school. Students are admitted for free! But we have a limited number of slots, register soon! Due to high requests, registration has been extended to May 31st 2019. Hurry up!

Seminar and lectures of Otavio Menezes in Roma1
by Faggionato, Alessandra 22 May '19

22 May '19

Buongiorno, la prossima settimana abbiamo ospite del Dipartimento il Dr. Otavio Menezes dell'Universita' di Lisbona, che terra' un seminario e due lezioni sul metodo di entropia per sistemi di particelle. Le lezioni sono pensate anche per studenti di dottorato. Sotto trovate i dettagli. Grazie Buona Giornata Alessandra *(A) Seminar* Monday 27 May, 16:00 Aula di Consiglio, Department of Mathematics, University La Sapienza Speaker: Otavio Menezes (Univsersity of Lisbon) Title: Relative entropy and scaling limits of interacting particle systems Abstract: We obtain product approximations to the law of particle systems with exclusion and Glauber dynamics in finite volume, by establishing a bound on the relative entropy between the law of the system and the product measure. As applications of the entropy estimate we obtain the scaling limits of the density fluctuation fields close of equilibrium and bounds on the speed of convergence of the hydrodynamic limit. Joint work with Milton Jara. *(B) Minicourse* When: Tuesday 28 May, 15:00-17:00 and Wednesday 29 May, 14:00-16:00. Where: Room B, Department of Mathematics, La Sapienza Speaker: Otavio Menezes (Univsersity of Lisbon) Title: Relative entropy and scaling limits of interacting particle systems Abstract: The relative entropy method was developed by H.T. Yau in the 90’s to study the hydrodynamics of the Ginzburg-Landau model, and then adapted to several different dynamics. In this course we present the Relative Entropy Method of Yau in the context of general continuous time Markov chains, as well as recent progress in the setting of exclusion and Glauber dynamics.
