Supporto per la Risk Transparency
by Antonella Basso 26 Dec '14

26 Dec '14

Cari Amici e Colleghi, dopo circa tre anni è ripartita l'iniziativa per la Risk Transparency da parte della Comunita' Europea. L'intento principale e' quello di utilizzare metodologie adeguate per misurare il grado di rischio dei diversi strumenti finanziari. E' molto importante che ci sia una larga partecipazione di persone competenti. Per sostenere il "Movement for Risk Transparency" e' sufficiente riempi re il form http://risktransparency.altervista.org/adhere-new-movement-risk-transparenc… ( semplicemente nome, cognome, affiliation e indirizzo mail) Di seguito una breve sintesi di tale iniziativa: Nel corso degli anni passati il “Movement for Risk Transparency” ha condotto importanti iniziative di promozione e supporto di un’efficace normativa di trasparenza informativa presso la Commissione Europea, l’ESMA e lo IOSCO. Nel novembre 2014, un’iniziativa congiunta di ESMA, EBA ed EIOPA (European Insurance and Occupational Authorities) riunite all’interno della Joint Commitee of European Supervisory Authorities (JCESA) ha prodotto un importante documento di consultazione sul tema chiave rappresentato dal Key Investor Document (KID) per i PRIIPS. Il documento tecnico è pubblicamente visionabile al link: http://www.esma.europa.eu/system/files/jc_dp_2014_02_-_priips_discussion_pa… In questo report la JCESA rimette in discussione l’approccio what-if precedentemente regolamentato nel caso dei fondi armonizzati (UCITS), facendo proprie gran parte delle critiche mosse a suo tempo dal “Movement for Risk Transparency”. Allo stesso tempo, viene richiesta un’esplicita valutazione di possibili implementazioni degli scenari di performance, anche attraverso l’indicazione delle probabilità. Non mancano domande dettagliate su temi centrali su cui “Movement for Risk Transparency” ha già preso in passato un’aperta posizione, come la rappresentazione dei costi – anche impliciti – del prodotto attraverso il calcolo del fair value o la determinazione di un opportuno orizzonte temporale. La pubblicazione di questo documento è un grande risultato, frutto dell’azione coordinata e coerente che il “Movement for RiskTransparency” ha tenuto nel corso degli anni. Ma deve essere un punto di partenza, non uno di arrivo: infatti, sulla base delle risposte alla consultazione la JCESA predisporrà le bozze dei c.d. Regulatory Technical Standards (RTS) snodo fondamentale per arrivare ad una regolamentazione europea pienamente trasparente. A tal fine, “Movement for Risk Transparency” ha predisposto un documento tecnico di risposta alla consultazione pubblica che alleghiamo alla presente lettera: nel documento si ripropongono i temi più importanti già affrontati ed ampiamente condivisi nelle precedenti iniziative, contestualizzati nell’ambito di intervento relativo ai PRIIPS. Ti invitiamo a prendere visione del documento di risposta e, se lo ritieni opportuno, di aderire all'iniziativa. È sufficiente riempire il form ed indicare la qualifica che vuoi appaia sulla lettera. Il termine per rispondere alla pubblica consultazione della JCESA è il 17 febbraio 2015; pertanto per esigenze organizzative ti preghiamo di inviare la tua adesione preferibilmente entro il 31 gennaio 2015. Grazie ancora per il supporto e sinceri Auguri di Buon Anno Rita D'Ecclesia -- Antonella Basso Dipartimento di Economia Università Ca' Foscari Venezia Fondamenta S.

Millossovich: Seminar at the Dept. of Economics, University Ca' Foscari of Venice
by Marco Corazza 16 Dec '14

16 Dec '14

Dear all, the Department of Economics, University Ca' Foscari of Venice, invite you to the seminar: ********************************************** Speaker: Pietro Millossovich (City University London, UK) ********************************************** Where/When: Room E, Dept. of Economics, San Giobe 873/b, Venice December 22/2014, 2.00pm ********************************************** Title: Two Populations Stochastic Mortality Models and Longevity Basis Risk ********************************************** Abstract: Longevity swaps provide an alternative de-risking solution for pension funds and life offices which has been gaining popularity in the recent years. While most swaps contracted so far are bespoke, an efficient market solution would require the hedging instrument to be standardized and based on a publicly available mortality index. In this case, it is crucial for the risk hedger to assess the extent of the basis risk left, which ultimately amounts to the difference between the book and the index mortality experiences. To this end, a two population mortality forecasting model is required. In this presentation, we address the choice of the most appropriate multi population mortality model basis risk assessment, discussing in particular the constraint due to the limited size of many existing pension books.

seminario al CNR-IMATI
by Antonella Bodini 15 Dec '14

15 Dec '14

Si ricorda che venerdi' 19 dicembre alle ore 11 presso la sede di Milano dell'IMATI, via Bassini 15, nella sala pentagonale al secondo piano, Ting WANG (University of Otago, New Zealand) terra' il seminario *Modelling of seismic activity using Markov-modulated Hawkes process and its extensions* Earthquakes are processes in which the internal workings are only observed indirectly, although the final effects are all too observable! Hidden Markov models (HMMs, a general statistical framework for modelling partially observed systems) are an intuitively attractive idea for analysing seismicity. I will introduce the Markov-modulated Hawkes process that we developed for investigating long-term patterns in seismicity rate. The catalogue of the Landers earthquake sequence, which included multiple mainshocks, was used as a case study. I will show how this model captures the cyclic parent-generating-offspring feature of the temporal behaviour of earthquakes. I will also discuss our current work on extending this temporal model by including spatial variation of the seismic activity and the earthquake magnitude. Our aim is to categorize spatiotemporal seismic hazards holistically, using the entire earthquake record in a selected region to identify patterns correlated with subsequent large earthquakes, rather than the traditional way of hunting for individual foreshocks. Tutti gli interessati sono invitati a partecipare. -- Dott.

Martedi 16 dicembre, alle ore 17, nella Sala dei Seminari del Dipartimento di Matematica dell'Universita' di Pisa, il prof. PETER BANK (Technische Universitat Berlin) terra' il seguente seminario: SUPERREPLICATION WHEN TRADING AT MARKET INDIFFERENCE PRICES Abstract We consider a large investor who seeks to superreplicate a given contingent claim. Trading is done dynamically at market indifference prices as introduced in earlier joint work with D. Kramkov. The nonlinearities of this model for an illiquid financial market turn out to make this fundamental problem surprisingly intricate as the usual tools from convex analysis to prove, e.g., existence cannot be applied. Moreover, it is possible (and economically nonetheless reasonable) that an asset can be replicated with two different initial levels of wealth without this creating arbitrage opportunities. We introduce a notion of efficient friction suitable for this price impact model and show how this ensures existence of optimal superrelicating portfolios under some assumptions on the market makers utility functions. We also establish efficient friction to hold when payoffs of traded assets are specified via Levy processes or certain affine processes, e.g., like in Barndorff-Nielsen-Shepard stochastic volatility models. This is joint work with Selim Gokay.

Avviso di seminario :: Kalcsics@DSS (Scienze Statistiche, Sapienza)

----------------------------------------------------------------------------- A v v i s o d i S e m i n a r i o ----------------------------------------------------------------------------- Lunedì 15 Dicembre, ore 12am ----------------------------------------------------------------------------- Stanza 34 Dipartimento di Scienze Statistiche Sapienza Università di Roma JOERG KALCSICS (Institute of Operations Research, Karlsruhe Institute of Technology) terrà un seminario dal titolo ON SALES & SERVICE DISTRICTING PROBLEMS tutti gli interessati sono invitati a partecipare. ----------------------------------------------------------------------------- Maggiori informazioni sui seminari presso il DSS sono consultabili a quest'indirizzo: http://goo.gl/Y6OQYm Saluti Pierpaolo Brutti --- ABSTRACT In sales districting, the task is to assign a given set of (prospective) customer accounts, each with a fixed market potential, to the individual members of the sales force such that each customer has a unique representative and each sales person faces equitable workload and has an equal income opportunity in terms of incentive pay, i.e., the districts should be balanced. Two other important planning criteria in sales districting are travel distances and clearly defined geographic areas of responsibility. The latter criterion is desired to avoid competition among the sales force and is typically termed as contiguity. Concerning travel distances, if a sales person visits each customer every day, then the travel time is proportional to the length of a TSP tour. However, the workload of districts is usually balanced over 2-4 weeks and some customers may have to be visited only once during this time whereas others require weekly service. Moreover, customers may have time windows, tours may include overnight stays, and so on, which makes the actual computation of the travel times impossible for large problems instances. Therefore, districting uses the concept of compactness as a proxy for travel distances. A district is said to be geographically compact if it is round-shaped and undistorted. The hope is that compact districts result in smaller travel times on a day-to-day basis than non-compact districts. A similar setting is encountered in service districting. In sales & service districting, customers are predominantly represented as points and although there exists a large body of literature, there is no consensus on a common compactness measure or suitable approaches to model contiguity of point sets. For example, all compactness measures are based on distances either between the center of a district and its basic units or between pairs of basic units of the same district. But even if they follow the same idea, the resulting districts may look considerably different. In this talk, we want to give an overview of different approaches to measure compactness and assess contiguity, and discuss their strengths and weaknesses when applied to practical problems. Moreover, we present a mathematical formulation to solve the districting problem optimally as well as an efficient geometric algorithm that is capable of coping with large practical problems.

*Venerdi' 19 Dicembre 2014*, *ore 11:30* Consiglio Nazionale delle Ricerche, Istituto per le Applicazioni del Calcolo "Mauro Picone", Via dei Taurini 19, 00185 Roma Aula Riunioni (secondo piano) *ENZO ORSINGHER* (Universita' di Roma "Sapienza") terra' un seminario dal titolo *Estensioni frazionarie del processo di Poisson* ABSTRACT: In questo seminario si presentano tre diverse estensioni frazionarie del processo di Poisson. La prima è la versione frazionaria rispetto al tempo dove si parte dalla equazione governante le probabilità di stato nelle quali appare la derivata frazionaria rispetto al tempo nella versione di Dzerbayshan-Caputo. Si ottengono le leggi di probabilità esplicite e una relazione con il processo di Poisson classico sotto forma di cambiamento del tempo. Si analizza anche la struttura del processo di Poisson frazionario come processo di rinnovo con intertempi con distribuzione di Mittag-Leffler. Una estensione del processo di Poisson chiamata Poisson frazionario nello spazio è analizzata e viene mostrato che si tratta di un processo ad incrementi indipendenti (a differenza della versione frazionaria rispetto al tempo), se ne ricava la distribuzione in diverse forme e si studiano le rispettive proprietà. Una terza versione del processo di Poisson come mistura di processi di Poisson omogenei è costruita e vengono discusse le sue applicazioni ai voli aleatori. Infine una classe più ampia di processi di Poisson a tempo riscalato e ad incrementi indipendenti è presentata assieme a specifiche forme legate a diverse scelte della misura di Lévy. Tutti gli interessati sono invitati a partecipare. Cordiali saluti, Giovanni Luca Torrisi.

Seminario di Giorgia Callegaro presso Prometeia - Bologna
by giacomo.scandolo＠unifi.it 09 Dec '14

09 Dec '14

Il giorno Martedì 16 Dicembre 2014, alle ore 14:30 presso la sede di Prometeia (sala grande, primo piano) via G.Marconi 43, Bologna Giorgia CALLEGARO (Università di Padova) terrà un seminario dal titolo "Pricing and Calibration in Local Volatility Models Via Fast Quantization" Abstract In this paper we propose the first calibration exercise based on quantization methods. Pricing and calibration are typically difficult tasks to accomplish: pricing should be fast and accurate, otherwise calibration cannot be performed efficiently. We apply in a local volatility context the recursive marginal quantization methodology to the pricing of vanilla and barrier options. A successful calibration of the Quadratic Normal Volatility model is performed in order to show the potentiality of the method in a concrete example, while a numerical exercise on barrier options shows that quantization overcomes Monte-Carlo methods.

Giovedì 11 Dicembre alle 12:30 presso l'aula seminari dell'ex Dipartimento di Studi del Lavoro, via Conservatorio 7, primo piano, a Milano, Giovanni Puccetti (Università degli Studi di Firenze) terrà un seminario dal titolo Extremal negative dependence concepts Tutti gli interessati sono invitati a partecipare. Abstract: While the concept of extremal positive dependence is agreed upon for random vectors of arbitrary dimension, various notions of extremal negative dependence arise when more than two random variables are involved. We will review popular existing concepts of extremal negative dependence given in the literature and introduce a novel notion, which in a general sense includes the existing ones as particular cases. Although much of the literature on dependence is actually focused on positive dependence, we will show that negative dependence plays an equally important role in the solution of many optimization problems. This talk is based on a joint work with Ruodu Wang, University of Waterloo.

A general framework to analyze these kinds of inexact data with statistical tools developed for Hilbertian random variables will be presented. Robust estimation in Hilbert spaces is specially relevant for its applications in the treatment of contaminated functional data. Specifically, the trimmed mean was already defined and analyzed under ideal conditions. However its estimation has not been efficiently implemented. An algorithm to compute the sample trimmed mean in Hilbert spaces is presented and its robust properties are briefly discussed. To show the performance of the algorithm some case studies concerning functional and fuzzy data will be presented.

We will mainly focus on the mean variation of random fields with stationary increments. We will show that this mean variation is proportional to the Lebesgue measure, and an expression of the constant of proportionality, called the variation intensity, will be established. This expression shows in particular that the variation intensity only depends on the family of two-dimensional distributions of the stationary increment random field. When restricting to random sets, the obtained results give generalizations of well-known formulas from stochastic geometry and mathematical morphology. The interest of these general results will be illustrated by computing the variation intensities of several classical stationary random field and random set models, namely Gaussian random fields and excursion sets, Poisson shot noises, Boolean models, dead leaves models, and random tessellations.
