seminario di Giovanni Zanco a Pavia
by Carbone Raffaella 27 May '15

27 May '15

Cari colleghi, vi annuncio che venerdì 29 Maggio 2015, alle ore 15 precise, presso la sala conferenze dell’IMATI-CNR di Pavia, Giovanni Zanco (Università di Pisa) terrà un seminario dal titolo: INFINITE DIMENSIONAL METHODS FOR PATH-DEPENDENT SDES: KOLMOGOROV EQUATIONS AND ITO FORMULAE nell'ambito del Seminario di Matematica Applicata (IMATI-CNR e Dipartimento di Matematica, Pavia). Tutti gli interessati sono invitati a partecipare. Abstract. Path-dependent stochastic differential equations are (non-markovian) equations whose coefficients are allowed to depend on the whole trajectory of the solution up to the present time, and are a powerful tool in modeling complex evolution systems with memory that appear in finance, engineering and biology. Even when the state space is finite dimensional, they are intrinsecally infinite dimensional. I will show how path-dependent SDEs can be studied in a product space framework (inspired by the theory for delay equations) using standard differential and topological structures. This framework is helpful to prove existence and uniqueness of classical solutions to path-dependent Kolmogorov-type PDEs on the space of continuous paths, to obtain probabilistic representation formulas for such solutions and moreover to prove Ito-type formulae for functionals of paths of continuous semimartingales, thus providing a counterpart of the functional Ito calculus developed by Dupire, Cont and Fournié. It also provides an insight on the role and the analytical structure of the so-called horizontal derivative, which is a key object in the study of path-dependent equations. The results I will present have been obtained in collaboration with Franco Flandoli (Unipi) and Francesco Russo (Ensta-ParisTech). -- Raffaella Carbone, PhD Ricercatore di Probabilità e Statistica Matematica Dipartimento di Matematica dell'Università degli Studi di Pavia

Seminar on Credit Risk by Andrea Pallavicini, Fri May 29 9:30 AM - 1:00 PM Aula Fermi @ SNS
by Giacomo Bormetti 25 May '15

25 May '15

Dear all, Friday May 29 2015, 9:30 - 11:00 AM and 11:30 AM - 1:00 PM in Aula Fermi, Scuola Normale Superiore Pisa Andrea Pallavicini Banca IMI, Milano and Imperial College, London will deliver the seminar "Credit Risk Modelling Before and After the Crisis" Abstract: The financial crisis started in 2007 has shown that any pricing framework must include from the very beginning the possibility of default of any market player. As a consequence derivative valuation and risk analysis have moved from exotic derivatives managed on simple single-asset classes to simple derivatives embedding credit risk and new, or previously neglected, types of complex and interconnected non-linear effects. Derivative valuation is adjusted to include counterparty credit risk and contagion effects along with funding costs due to collateral posting, treasury policies, and regulatory constraints. A second level of complexity is produced by moving from a single trade to the whole bank portfolio. Aggregation-dependent valuation processes, and theirs operational challenges, arising from non-linearities are discussed both from a mathematical and practical point of view. All interested people are kindly invited.

Seminario di Robert Morris a Roma Tre il 29/05/15
by Pietro Caputo 21 May '15

21 May '15

Prof. R. Morris (IMPA, Brasile) Titolo: Universality for bootstrap percolation in two dimensions Venerdi' 29 Maggio 2015 ORE 14:30 Dipartimento di Matematica e Fisica Universita' degli Studi Roma Tre AULA 211 (Largo San L. Murialdo,1 - Palazzina C) Abstract: In the classical r-neighbour bootstrap percolation model on a graph G, vertices are initially infected independently at random with probability p, and subsequently vertices become infected as soon as they have at least r already-infected neighbours. In this talk we will discuss a vast generalization of this model on the lattice Z^d, which was introduced recently by Bollobas, Smith and Uzzell. Somewhat surprisingly, it turns out that in two dimensions there are only a small number of possible behaviours. We will discuss what is known so far, and the many open questions in higher dimensions. This is joint work with Bela Bollobas, Hugo Duminil-Copin and Paul Smith.

Saldini, 50, Milano, "Information coding in vestibular hair cells" Paola PERIN University of Pavia Abstract: Hair cells are the mechanoreceptors in our auditory and vestibular systems. Vestibular afferent neurons are classified on the basis of their motion selectivity (direction, response to linear vs. angular motion), discharge regularity, gain and dynamics (tonic vs. phasic). The properties of vestibular hair cells and afferent fibers are optimized for the transduction for low frequency stimuli (head motion, mostly below 50 Hz). Moreover, vestibular hair cells display a resting transmitter release rate which is used to set a baseline: increases above resting discharge signal movements in one direction, decreases signal movements in the opposite direction. Whereas discharge regularity appears to be a postsynaptic property, afferent dynamics is determined presynaptically, but the mechanisms involved are still unclear. In our work we have recorded currents, voltages and release from vestibular hair cells from the frog utricle and built a model of a hair cell connected to an afferent fiber upon mechanical stimulation. Our results suggest that dynamics is affected by ion currents (especially BK and IA) whereas presynaptic release properties affect resting discharge but not postsynaptic dynamics. ================ Per chi volesse seguire il seminario in remoto ricordo inoltre che sarà possibile dopo aver segnalato il proprio interessamento entro le 12 del giorno del seminario. ================= Reading Group Seminars: The Reading Group Seminars (RGS) are organized within an open community of researchers interested in applying up to date mathematical modeling and data analysis approaches to the study of biological systems.

**************************************************************** STATISTICS SEMINARS @ COLLEGIO CARLO ALBERTO **************************************************************** Venerdi 22 Maggio 2015 alle ore 12:00, presso l’Aula Rossa del Collegio Carlo Alberto, Moncalieri (TO), si terra' il seguente seminario: Luca TARDELLA (Università di Roma "La Sapienza”) FLEXIBLE BEHAVIORAL CAPTURE-RECAPTURE MODELLING Abstract: We develop some new strategies for building and fitting new flexible classes of para- metric capture-recapture models for closed populations which can be used to address a better understanding of behavioural patterns. We first rely on previous approaches based on a conditional probability parameterization and review how to regard a large subset of standard capture-recapture models as a suitable partitioning in equivalence classes of the full set of conditional probability parameters. We then propose a regression approach combined with the use of new suitable quan- tifications of the conditioning binary partial capture histories as a device for enlarging the scope of flexible behavioural models and also exploring the range of all possible partitions. We show how one can easily find unconditional MLE of such models within a generalized linear model framework. We illustrate the potential of our approach with the analysis of some known datasets and a simulation study. Tutti gli interessati sono invitati a partecipare.

de Finetti Risk Seminar - May 2015
by Emanuela Rosazza 14 May '15

14 May '15

On behalf of the Scientific Committee of the de Finetti Risk Seminars, we are glad to invite you to participate at the following Lecture Financial Models with Defaultable Numeraires Johannes Ruf University College London ABSTRACT Financial models are studied where each asset may potentially lose value relative to any other. To this end, the paradigm of a pre-determined nume raire is abandoned in favour of a symmet- rical point of view where all assets have equal priority. This approach yields novel versions of the Fundamental Theorems of Asset Pricing, which clarify and extend non-classical pricing formulas used in the financial community. Furthermore, conditioning on non-devaluation, each asset can serve as nume raire and a classical no-arbitrage condition be formulated. It is shown when and how these local conditions can be aggregated to a global no-arbitrage condition. Joint work with Travis Fisher and Sergio Pulido LOCATION: The seminar will be held on Wednesday, May 20, at 18.00, Aula di Rappresentanza, Dipartimento di Matematica, Università di Milano, Via Saldini 50, Milano. A refreshment will be offered at 17.30. Scientific Committee: Prof. Marco Frittelli (Univ. degli Studi di Milano) Prof. Fabio Maccheroni (Univ. Bocconi) Prof. Massimo Marinacci (Univ.

Seminario di Probabilita' - Universita' di Padova
by alessandra bianchi 12 May '15

12 May '15

Ho il piacere di invitarvi al seguente seminario, che si terrà lunedì 18 maggio alle ore 14:30 nell'aula 2BC30 del Dipartimento di Matematica dell'Universita' degli Studi di Padova. SPEAKER: Stefan Grosskinsky (Mathematics Institute, University of Warwick) TITLE: Metastability in condensing zero-range processes ABSTRACT: We consider a zero-range process with jump rates decreasing with the occupation number, which is known to exhibit a condensation phenomenon where a finite fraction of all particles concentrates on a single lattice site. We derive a scaling limit for the asymptotic stationary dynamics of the condensate location in the thermodynamic limit on a one-dimensional torus. Our proof follows previously developed methods using potential theory and a martingale approach, which have been applied to zero-range processes on finite lattices. The main challenge and novelty of our paper arises from the absence of attractor states which complicates the proof of equilibration within metastable wells and requires a coupling argument to get uniform bounds on exit rates from wells. This is joint work with Ines Armendariz and Michalis Loulakis. -- Alessandra Bianchi Dip. di Matematica Università di Padova Via Trieste, 63 - 35121 Padova, Italy phone: +39 049 827 14 06 fax: +39 049 827 14 28 e-mail: bianchi(a)math.unipd.it http://www.math.unipd.it/~bianchi/

Giovanni Luca Torrisi (CNR-Istituto per le Applicazioni del Calcolo) Title Probability approximation of spatial point processes Abstract: We give a quantitative Gaussian and Poisson approximation for the first chaos (or innovation) of spatial point processes with conditional intensity. To this aim we use a Malliavin-Stein-Chen approach. This method is essentially based on the following two steps. First, we provide an integration by parts (IBP) formula which relates the first chaos with the discrete Malliavin operator. Second, we derive the probability approximations by combining the IBP formula with the Stein and Chen methods. Our findings extend the corresponding results on the Poisson space due to Peccati, Solè, Taqqu and Utzet (2010) and Peccati (2011). The general bounds presented in this talk are applied to stationary, inhibitory and finite range Gibbs point processes with pair potential, providing explicit error bounds and quantitative limit theorems. Tutti gli interessati sono invitati a partecipare. Saluti Alessandro De Gregorio

International Conference in Venice - CALL FOR PAPERS - deadline 15th of May
by Monica Billio 07 May '15

07 May '15

14th INTERNATIONAL CONFERENCE C R E D I T 2015 *Societal Fault Lines and Credit Risk: The Impact of Current Economic, Institutional and Political Developments on Credit and Risk* Venice, Italy 1 - 2 October 2015 *GRETA Associati *(Venice, Italy), *Center on Sustainable Architecture for Finance (SAFE) at Goethe University Frankfurt* (Frankfurt, Germany), the *University of Zurich* (Zurich, Switzerland) and *Intesa Sanpaolo *(Milan, Italy) are co-sponsors of a Conference to be held in Venice on October 1-2, 2015. The objective of the Conference is to bring together academics, practitioners and PhD 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 events in financial markets 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 *and *European Investment Bank*, is the *fourteenth* of a series dedicated to various aspects of credit risk. The organizers encourage submissions of papers on any topic within the overall theme of the conference and in the following areas in particular: * *Wealth inequality, firm financing and credit risk* o Is local wealth inequality affecting the quality of institutions and the choice over market versus bank finance, and thereby determining corporate finance and credit risk outcomes? * *Home ownership and credit risk* o Are measures promoting home ownership or financial innovations responding to an increase in ownership demand, for example, resulting in more credit risk? * *Collateral availability, credit and risk* o Is the availability of collateral determining credit granting and credit risk? * *Banking supervision and credit risk* o Is the level and quality of bank supervision leading to an optimal level of credit risk? o What is the impact of the institutional organization of banking supervision on credit risk? * *Central bank policies and credit risk* o Are monetary conditions drivers of bank credit risk taking?

In the case that the rssMp is taken to be an α-stable process with α ∈ (0,2), the characteristics of the matrix exponent of the semi-group of the embedded MAP (the Lamperti-stable MAP) are computed. Specifically, the matrix exponent of the Lamperti-stable MAP’s transition semi-group can be written in a compact form using only gamma functions. Just as with Lévy processes, there exists a factorisation of the (matrix) exponents of MAPs, with each of the two factors uniquely characterising the ascending and descending ladder processes, which themselves are again MAPs. To our knowledge, not a single example of such a factorisation currently exists in the literature. In this talk we provide a completely explicit Wiener-Hopf factorisation for the Lamperti-stable MAP. As a consequence of our methodology, we also get additional new results concerning space-time invariance properties of stable processes. --- Matteo Ruggiero University of Torino and Collegio Carlo Alberto www.matteoruggiero.it

The choice of a model for the analysis of data depends on the purpose of the analysis, the nature of the data, and also on the sample or data size. Erev, Roth, Slonim and Barron (2007) [Economic Theory, 33, 29–51] studied models for prediction of future play in game-theoretic experiments and proposed an approach for quantification of the value of a model. Combining ideas from the latter article and the well-known AIC criterion, we propose another quantification of the chosen model's relative predictive value, which depends on the data and its size. Our research was first motivated by data from experimental economics, and we also study the Hardy-Weinberg model in biology.

Cari amici vi invito a partecipare al seminario di Max Fathi (Università di Parigi Jussieu) presso il dipartimento di matematica dell'università di Roma La Sapienza (sito in piazzale Aldo Moro 5, Roma), i cui dettagli sono riportati di seguito. A presto Mauro Mariani Data ed aula: lunedì 11 maggio, ore 14:30, aula di consiglio (primo piano) Titolo: A gradient flow approach to large deviations for diffusion processes Sunto: In the 80s, De Giorgi introduced the notion of abstract gradient flows, which allowed to define a notion of solutions to ordinary differential equations of the form x' = −grad F(x) on metric spaces (rather than Riemannian manifolds for the usual definition). In 2005, Ambrosio, Gigli and Savare showed that when we consider the space of probability measures on R d endowed with the Wasserstein metric, this notion allows to give an alternate formulation for Fokker-Planck equations. These equations are the PDEs whose solutions are the flow of marginals of solutions of stochastic differential equations of the form dX = −grad H(X)dt + dB . In this talk, I will explain how we can use this notion to study large deviations for sequences of SDEs. The main result is that proving a large deviation principle is equivalent to studying the limit of a sequence of functionals that appear in the abstract gradient flow formulation for Fokker-Planck equations. As an application, I will show how to obtain large deviations from the hydrodynamic scaling limit for a system of interacting continuous spins in a random environment.

Murialdo,1 Abstract: The hard disk model describes random configurations of disks in the plane, interacting only via hard core exclusion. It is believed that the model exhibits a weak form of crystallization for large activity (i.e. high particle density). In spite of its simplicity, there are only very few rigorous results on the hard disk model. I will present a very recent result which can be interpreted as a lower bound on the variance of particle positions in terms of the size of the system. The result is obtained via a certain tansformation on particle configurations. It builds on an earlier result concerning the absence of positional order.

We solve exactly the Hausdorff moment problem for these numbers and provide explicit expressions for appropriate positive weight functions. For certain values of parameters we analyse the properties of these solutions from the point of view of the free probability, and demonstrate their infinite divisibility with respect to the free additive convolution.

Yinon Spinka (Tel Aviv) Title: Long-range order in random 3-colorings When: Martedi' 19 Maggio 2015 ORE 14:00 Where: Dipartimento di Matematica e Fisica Universita' degli Studi Roma Tre AULA 311 (SEMINARI), Largo San L. Murialdo, 1 Abstract: We study the anti-ferromagnetic 3-state Potts model of statistical physics. In this model, one samples a random coloring of a box in Z^d with 3 colors, with the probability of a coloring f being proportional to exp(-beta*N(f)), where beta>0 is a parameter (representing the inverse temperature) and N(f) is the number of edges connecting vertices colored with the same color. Our main result is that in high dimensions and low temperature (large beta), a sampled coloring will typically exhibit long-range order, placing the same color at most of either the even or odd vertices of the box. This extends previous work of Galvin, Kahn, Peled, Randall and Sorkin. The main ingredient in our proof is a new structure theorem for 3-colorings which characterizes the ways in which different "phases" may interact, putting special emphasis on the role of edges connecting vertices of the same color. We also discuss several related conjectures. No background in statistical physics will be assumed and all terms will be explained. Joint work with Ohad Feldheim.

Prof. Quentin Berger (Universita' Parigi 6) When: Mercoledi 13 maggio ore 11, Where: Aula 211, Pal. C Dip. Matematica e Fisica, RomaTre, Largo San L. Murialdo, 1 - 00146 Roma Title: Disorder relevance for the pinning model (joint work with Hubert Lacoin) Abstract: A central question in the study of disordered systems (and in particular of their phase transition) is that of disorder relevance: one wants to determine whether an arbitrarily small quantity of disorder affects or not the critical behavior of the system. The physicist Harris provided a simple and general criterion to know whether disorder was relevant or irrelevant for a given d-dimensional system. In this talk, we will introduce the pinning model, a family of disordered systems, which has attracted much attention in the past decade: it considers a 1-dimensional polymer chain interacting with an inhomogeneous defect line, undergoing a localization phase transition. For this model, Harris' prediction has been rigorously proved, but the marginal case (for which Harris criterion gives no prediction) was partially left open. We will present here a necessary and sufficient condition for disorder relevance for the pinning model, solving completely the question for this model.

Dear all, Wednesday May 6 2015, 1:00 PM in Aula Bianchi, Scuola Normale Superiore Pisa Massimiliano Caporin Department of Economics and Management "Marco Fanno" - Università di Padova will deliver the seminar "The impact of network connectivity on factor exposures, asset pricing and portfolio diversification" Abstract: The need for understanding the propagation mechanisms behind the recent financial crises lead the increased interest for works associated with asset interconnections. In this framework, network-based methods have been used to infer from data the linkages between institutions. In this paper, we elaborate on this and make a step forward by introducing network linkages into linear factor models. Networks are used to infer the exogenous and contemporaneous links across assets, and impacts on several dimensions: network exposures act as in inflating factor for systematic exposure to common factors with implications for pricing; the power of diversication is reduced by the presence of network connections; in the presence of network links a misspecied traditional linear factor model provides residuals that are correlated and heteroskedastic. We support our claims with an extensive simulation experiment. Joint work with Monica Billio, Roberto Panzica, and Loriana Pelizzon. All interested people are kindly invited.

Seminari di Eckhard Platen all'Università di Firenze

Ricordo che il Prof. Eckhard PLATEN (University of Technology, Sydney) questa settimana terrà due seminari presso il Dipartimento di Scienze per l'Economia e l'Impresa Edificio D6, via delle Pandette, 32, Firenze Tutti gli interessati sono invitati a partecipare ============================================================= Giovedì 7 Maggio, 10.00-12.00, aula D6/105 ''Numerical Solutions of Stochastic Differential Equations with Jumps in Finance '' Abstract. In financial and actuarial modelling and other areas of application, stochastic differential equations with jumps have been employed to describe the dynamics of various state variables. The numerical solution of such equations is more complex than that of those only driven by Brownian motions. The aim of this lecture is to present various numerical methods used in quantitative finance for models involving stochastic differential equations with jumps. It emphasises mathematical concepts, techniques and intuition crucial for modern numerical methods in derivative pricing and risk management. Questions of numerical stability and convergence will be discussed. Several recent results will be presented on higher-order methods for scenario and Monte Carlo simulation, including implicit, predictor corrector and extrapolation methods. ============================================================= Venerdì 8 Maggio, 10.00-12.00, aula D6/013 "A Benchmark Approach to Finance " Abstract. This lecture introduces into the benchmark approach, which provides a generalized framework for financial market modelling. It allows for a unified treatment of derivative pricing, portfolio optimization and risk management. It extends beyond the classical asset pricing theories, with significant differences emerging for extreme maturity contracts and risk measures relevant to pensions and insurance. The Law of the Minimal Price will be presented for derivative pricing. A Naïve Diversification Theorem allows forming a proxy for the numeraire portfolio. The richer modelling framework of the benchmark approach leads to the derivation of tractable, realistic models under the real world probability measure. It will be explained how the approach differs from the classical risk neutral approach. Examples on long term and extreme maturity derivatives demonstrate the important fact that a range of contracts can be less expensively priced and hedged than suggested by classical theory. --- Questa e-mail è priva di virus e malware perché è attiva la protezione avast!

ANNUNCIO DI SEMINARIO Il Prof. Eckhard Platen, professore alla University of Technology di Sydney ed attuale Presidente della Bachelier Finance Society, terra' il seguente seminario dalle 14.30 alle 15.30 del martedi' 5 maggio in aula 2BC60 del Dipartimento di Matematica, via Trieste 63, Padova. (Si noti lo spostamento dalla originale aula 2AB40 alla 2BC60) Referente: W. Runggaldier __________________ TITLE: BENCHMARKED RISK MINIMIZATION ABSTRACT: The paper discusses the problem of hedging not perfectly replicable contingent claims by using a benchmark, the numeraire portfolio, as reference unit. The proposed concept of benchmarked risk minimization generalizes classical risk minimization, pioneered by Foellmer, Sondermann and Schweizer. The latter relies on a quadratic criterion, requesting the square integrability of contingent claims and the existence of an equivalent risk neutral probability measure. The proposed concept of benchmarked risk minimization avoids these restrictive assumptions. It employs the real world probability measure as pricing measure and identifies the minimal possible price for the hedgeable part of a contingent claim. Furthermore, the resulting benchmarked profit and loss is only driven by nontraded uncertainty and forms a martingale that starts at zero. Benchmarked profit and losses, when pooled and sufficiently independent, become in total negligible. This property is highly desirable from a risk management point of view. It is making asymptotically benchmarked risk minimization the least expensive method for pricing and hedging of an increasing number of not fully replicable benchmarked contingent claims.

SEMINARIO DI PROBABILITA' E FISICA STATISTICA Giovedi' 7 Maggio, ore 14.30 , in Aula B (Dipartimento di Matematica. Univ.La Sapienza, Roma) Speaker: Andrea Puglisi (Istituto dei Sistemi Complessi, Sapienza) Title: Dynamics of an intruder in a granular fluid: from dilute to dense experiments. A single experimental setup is the occasion for a tour into many issues in non-equilibrium statistical mechanics. In the experiment, a rotating intruder performs a Brownian-like dynamics under the influence of collisions with a shaken granular media. Dissipations in the form of inelastic collisions and dry tangential friction make the system inherently out of equilibrium. When the granular medium is diluted, the results agree with a Boltzmann-Lorentz description which, in the large mass limit, is well approximated by a Fokker-Planck equation for a Ornstein-Uhlenbeck process with Coulomb friction. When the intruder is shaped so as to break the symmetry under rotation-inversion, an average drift ("ratchet" or "motor" effect) is observed, with properties depending on the dominant dissipation: friction or inelastic collisions. When the density of the surrounding medium increases, non-Markovian effects appear. The first consequence is a violation of the Einstein relation which - near equilibrium - describes the linear response to a small force provided by an external motor. The analysis of a generalized flctuation-dissipation relation explains the nature of the violation: a joint effect of dissipation and coupling with the dense flid. When the density is increased further and the jamming transition is approached, anomalous diffusion appears in the form of transient cage effects (subdiffusion) and - more surprisingly - superfdiffusion at large times. -- Prof. Alessandra Faggionato Department of Mathematics University La Sapienza Piazzale A.

Fwd: Annuncio Seminario Vlad Bally - 27 Aprile - Tor Vergata
by Claudio Durastanti 24 Apr '15

24 Apr '15

Ciclo di Seminari - Progetto ERC grant PASCAL (Probabilistic and Statistical Techniques for Cosmological Applications) Lunedì 27 aprile - ore 14 - aula D'Antoni Speaker Vlad Bally, Universite' Paris-Est LAMA, INRIA title: Convergence and regularity of probability laws by using an interpolation method Abstract: In a recent paper, Fournier and Printems establish a methodology which allows to rove the absolute continuity of the law of the solution of some stochastic equations with Holder continuous coefficients. This is of course out of reach by using already classical probabilistic methods based on Malliavin calculus. In this context, Debussche and Romito employ some Besov space technics in order to substantially improve the result of Fournier and Printems. In this talk we show that this kind of problem naturally fits in the framework of interpolation spaces: we prove an interpolation inequality which allows to state (and even to slightly improve) the above absolute continuity result. Moreover it turns out that the above interpolation inequality has applications in a completely different framework: we use it in order to estimate the error in total variance distance in some convergence theorems. Tutti gli interessati sono invitati a partecipare. Cordiali saluti, Claudio Durastanti

Two seminars and presentation of Ph.D. thesis, Friday April 24
by Tiziano Vargiolu 21 Apr '15

21 Apr '15

(sorry for possible cross-posting) We have the pleasure to announce the following two seminars, in University of Padova, Italy Department of Mathematics, via Trieste 63 room 1BC/45, 1st floor Friday, April 24 9.00 Zorana GRBAC: "Discrete-tenor interest rate models based on polynomial preserving processes" ABSTRACT: Based on the class of polynomial preserving Markov processes, we construct families of positive martingales, which are monotone with respect to some parameter. Such martingales are particularly suitable for modeling of discretely compounded forward interest rates via additive constructions. This includes Libor-type models, as well as extensions to the multiple-curve term structure. The main advantage of this model class is the possibility to obtain semi-analytic pricing formulas for both caplets and swaptions that do not require any approximations. Moreover, additive constructions allow to easily ensure, if desired, properties such as positivity of interest rates and spreads and monotonicity of spreads with respect to the tenor - in view of the current market situation a model in which the reference OIS interest rates can become negative and the spreads still remain positive is of particular interest. Examples of tractable and flexible model specifications that we study include quadratic OU-Gaussian and OU-L?vy processes, as well as linear models. We discuss the efficient option pricing via Fourier methods and develop the necessary exponential transform formulas for polynomial preserving processes. This is joint work with K. Glau and M. Keller-Ressel. 10.00 Antonis PAPAPANTOLEON: "An equilibrium model for spot and forward prices of commodities" ABSTRACT The aim of this project is to determine the forward price of a consumption commodity via the interaction of agents in the spot and forward commodity market. We consider a market model that consists of three agents: producers of the commodity, consumers and financial investors (sometimes also called speculators). Producers produce a fixed amount of the commodity at each time point, but can choose how much they offer in the spot market and store the rest for selling at the next time period. They also have a position in forward contracts in order to hedge the commodity price uncertainty. Consumers are setting the spot price of the commodity at each time point by their demand. Finally, investors are investing in the financial markets and, in order to diversify their portfolios, also in the forward commodity market. The equilibrium prices for the commodity are the ones that clear out the spot and forward markets. We assume that producers and investors are utility maximizers and have exponential preferences, while the consumers' demand function is linear. Moreover, the exogenously priced financial market and the demand function are driven by L?vy processes. We solve the maximization problem for each agent and prove the existence of an equilibrium. This setting allows to derive explicit solutions for the equilibrium prices and to analyze the dependence of prices on the model parameters and the agent's risk aversion. This is joint work with Michail Anthropelos and Michael Kupper. After the two seminars, the defenses of a PhD thesis will take place: 11.00 Giulio MIGLIETTA: "Topics in interest rate modeling" (supervisor: Martino Grasselli) See you all in Padova!
