(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!

seminario Valeria Bignozzi in Bicocca
by Fabio Bellini 20 Apr '15

20 Apr '15

Il giorno venerdì 24 aprile alle ore 14.00 presso la aula seminari del Dipartimento di Statistica e Metodi Quantitativi della Università di Milano-Bicocca (edificio U7, IV piano), la dott.ssa Valeria Bignozzi della Università di Firenze terrà un seminario su: Reducing model risk using positive and negative dependence assumptions Abstract We give analytical bounds on the Value-at-Risk and on convex risk measures for a portfolio of random variables with fixed marginal distributions under an additional positive dependence structure. We show that assuming positive dependence information in our model leads to reduced dependence uncertainty spreads compared to the case where only marginals information is known. In more detail, we show that in our model the assumption of a positive dependence structure improves the best-possible lower estimate of a risk measure, while leaving unchanged its worst-possible upper risk bounds. In a similar way, we derive for convex risk measures that the assumption of a negative dependence structure leads to improved upper bounds for the risk while it does not help to increase the lower risk bounds in an essential way. As a result we find that additional assumptions on the dependence structure may result in essentially improved risk bounds (joint work with G. Puccetti and L. Ruschendorf). Tutti gli interessati sono invitati a partecipare.

Seminari di Klaus Schredelseker e Eckhard Platen a Firenze
by Giacomo Scandolo 17 Apr '15

17 Apr '15

Nell'ambito del Corso di Laurea Magistrale in Finance and Risk Management (FiRM) dell'Università di Firenze i Proff Klaus SCHREDELSEKER (University of Innsbruck) e Eckhard PLATEN (University of Technology, Sydney) terranno i seguenti 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 Gli abstract degli interventi sono riportati in basso. ============================================================= Prof Klaus SCHREDELSEKER Martedì 5 Maggio, 14.00-16.00, aula D6/007 ''Financial Analysis and Efficient Markets '' Mercoledì 6 Maggio, 12.00-13.30 e 14.30-16.00, aula D6/102 "Information Economics applied to Financial Markets " ============================================================= Prof Eckhard PLATEN Giovedì 7 Maggio, 10.00-12.00, aula D6/105 ''Numerical Solutions of Stochastic Differential Equations with Jumps in Finance '' Venerdì 8 Maggio, 10.00-12.00, aula D6/013 "A Benchmark Approach to Finance " ============================================================= Abstract. ''Financial Analysis and Efficient Markets '' (Schredelseker) Financial Analysis is the basic of any type of financial reasoning (portfolio theory, capital market theory, derivatives). How it has to be done depends primarily upon the properties of the market: If it is assumed to be informationally efficient, financial analysis is redundant, but if this is the case, the market cannot be efficient. If, however, the market is assumed to be somewhat inefficient, there will be systematic winners and losers: Being a complex adaptive system, the financial market will exhibit nonlinearities in information. "Information Economics applied to Financial Markets " (Schredelseker) In natural sciences the value of information is always bound from zero: it can never be negative. This does not hold in multiperson-settings like a financial market: Getting better informed may result in a better or in a lower decision quality! A highly skilled and experienced financial analyst is assumed to expect a lower performance in the market as a lousy analyst. Methodology: Game theory, Agent-based modelling, Simulations, Genetic programming. ''Numerical Solutions of Stochastic Differential Equations with Jumps in Finance '' (Platen) 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. "A Benchmark Approach to Finance " (Platen) 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!

Seminario di Valeria Bignozzi presso Prometeia - Bologna
by Giacomo Scandolo 17 Apr '15

17 Apr '15

Il giorno Giovedì 23 Aprile 2015, alle ore 14:30 presso la sede di Prometeia (sala grande, primo piano) via G.Marconi 43, Bologna Valeria BIGNOZZI (Università di Firenze) terrà un seminario dal titolo "How superadditive can a risk measure be?" Abstract Risk measures that are not subadditive may penalize the aggregation of risk, by inducing portfolio requirements that are larger than those of undiversified positions. This happens for instance for Value-at-Risk (VaR), as well as convex shortfall risk measures. In this paper we characterize the potential for superadditivity that any risk measure may exhibit, considering both dependence uncertainty as well as the effect of portfolio size. It is shown that for the wide majority of risk measures of use or interest this corresponds to calculating the smallest dominating coherent risk measure (SDCRM). We show that this risk measure often exists and is identified with the notion of extreme-aggregation risk measure introduced in this paper. Explicit results are provided for the class of distortion risk measures, where the SDCRM is again a distortion risk measure and for the class of shortfall risk measures, where the SDCRM is given by an expectile. --- Questa e-mail è priva di virus e malware perché è attiva la protezione avast!

This paper analyzes, given the sequential nature of reviews and the limited feedback of such past reviews, the information content they communicate to future customers. We focus on the informational setting in which customers only observe the sample mean of past reviews, and ask if customers can recover the true quality of the product based on the feedback they observe. We first analyze the benchmark setting, in which customers interpret the mean as the proxy of quality. In such a case, we show that in the long run,the sample mean of review stabilizes and two cases may arise.If customers are relatively homogeneous, then social learning takes place. If customers are sufficiently heterogeneous, then they consistently overestimate the underlying quality of the product in the long run. This bias stems from the selection associated with observing only reviews of customers who purchase. We show, however,that if customers are sophisticated, then there exists a simple quality inference and purchasing rule that corrects for the selection bias and leads to social learning.In addition, we show that the cumulative consumer surplus losses scale with the square root of the number of customers who have considered a purchase to date, which is of the same order as when customers observe the reviews of all preceding customers. In this framework, we also analyze the externality of sophisticated customers on more naïve ones and quantify the impact that manipulated reviews may have.

Santiago Juan Saglietti Universita' di Buenos Aires Titolo: Metastability for small random perturbations of a PDE with blow-up Venerdi' 17 Aprile 2015 ORE 14:30 Dipartimento di Matematica e Fisica Universita' degli Studi Roma Tre AULA 311 (SEMINARI) Largo San L. Murialdo,1 Abstract We consider the stochastic PDE $u_t = u_{xx} + u^p + varepsilon dot{W}$ with homogenous Dirichlet boundary conditions, where $p > 1$, $varepsilon > 0$ is a small fixed parameter and $dot{W}$ stands for space-time white noise. It is well known that the associated deterministic PDE (i.e. $varepsilon = 0$ in the equation above) admits exactly one asymptotically stable equilibrium and a countable family of unstable equilibria with increasing energy. Furthermore, for certain initial conditions it can be shown that the solution of the deterministic PDE explodes in finite time. We show that, for $p < 5$ and initial conditions in the domain of attraction of the asymptotically stable equilibrium, the solution $X_varepsilon$ of the SPDE satisfies in the limit as $varepsilon$ tends to zero the classical description of metastability featured in [1]: the averages of $X_varepsilon$ remain stable and close to the equilibrium up until the explosion time which, when suitably rescaled, converges in distribution to an exponential random variable. Furthermore, for certain initial conditions in the domain of explosion (and any value of $p > 1$) we show the continuity of the explosion time as $varepsilon$ tends to zero.

Cambio orario: seminario Anna Carpio 14 aprile 2015
by Alessandra Micheletti 09 Apr '15

09 Apr '15

invio nuovamente l'annuncio, a causa di un piccolo spostamento di orario: *ANNUNCIO DI SEMINARIO* Il *14 aprile alle ore 15.30* nell'aula C del Dipartimento di Matematica, Universita' degli Studi di Milano, via Saldini 50, Milano si terrà un seminario sulla teoria dell'esistenza ed unicità di particolari equazioni integro-differenziali. *Speaker: *Anna Carpio (Universitad Carlos III Madrid) *Title:* *Well posedness of a kinetic model for angiogenesis* *Abstract.* Tumor induced angiogenesis processes including the effect of stochastic motion, branching and merging of blood vessels can be described by coupling an integro-differential kinetic equation of Fokker-Planck type with a reaction-diffusion equation for the tumor induced angiogenic factor (TAF). The chemotactic force field depends on the gradient of the TAF equation contains the first velocity moment (flux of blood vessels). We develop an existence and uniqueness theory for this system under natural assumptions on the initial data. Our theory combines the construction of fundamental solutions for associated linearized problems with comparison principles, sharp estimates of the velocity moments and compactness results for this type of kinetic and parabolic operators. -- ___________________________________________________________ Dr. Daniela Morale Dept.

Seminario all'IAC
by Giovanni Luca Torrisi 08 Apr '15

08 Apr '15

*Martedi' 14 Aprile 2015*, *ore 14:00* Consiglio Nazionale delle Ricerche, Istituto per le Applicazioni del Calcolo "Mauro Picone", Via dei Taurini 19, 00185 Roma Aula Riunioni (II piano) *CLAUDIO DURASTANTI * (Universita' di Roma Tor Vergata) terra' un seminario dal titolo *Normal approximations of linear and nonlinear statistics over the sphere.* ABSTRACT: Our aim is to study quantitative central limit theorems for some linear and nonlinear statistics based on wavelet coefficients evaluated on spherical Poisson processes of arbitrary dimension. This purpose is attained by merging the Stein-Malliavin approach (introduced in the seminal paper by Peccati, Solè, Taqqu and Utzet (2010)) and the properties of the needlets, wavelets over the q-dimensional sphere featuring strong concentration properties in the spatial and frequency domains, introduced in literature by Narcowich, Petrushev, Ward (2006). We will also discuss some examples: the thresholding and the study of variance in nonparametric density estimation framework and the so- called Sobolev tests for uniformity. This is a joint work with Solesne Bourguin, Domenico Marinucci and Giovanni Peccati. Tutti gli interessati sono invitati a partecipare. Cordiali saluti, Giovanni Luca Torrisi.
