This class of process was introduced in finance by Carr and Wu (2004) for pricing of equity derivatives. However, recently, empirical studies, as Leippold and Str?mberg (2014), suggest the application of time-changed L ?evy process to interest rate financial products. In particular, L ?evy processes generate very flexible return innovation distribution and take into account potential discontinuities in Libor dynamics. On the other hand, the time change and the dependence between the L ?evy process and the random time introduce ?stochastic volatility? and ?stochastic skew? in the model, in order to reproduce the term structure of the volatility smile of caps and swaptions. This paper is inspired by the work of Eberlein and Raible (1999) on L ?evy models, generalized in Crepey et al. (2014) to a multiple curve setting. To the best of our knowledge, no previous works present a theoretically consistent no-arbitrage framework for pricing interest rate derivatives with time-changed L ?evy process. Moreover we apply these flexible processes to a multiple-curve post crisis set-up. First of all, we build a term structures for zero coupon bonds and Libor forward rate and we derive sufficient conditions to ensure the absence of arbitrage. Moreover the pricing of interest rate derivatives, as caps and swaptions, is developed using the Fourier transform method. Finally different choices for the construction of the driving process are examined and compared. Il seminario si terra' presso la sede di Prometeia a Bologna in Via Marconi 43. -- Disclaimer: http://www.prometeia.it/disclaimer

PhD position in statistics of extremes -- TU Delft
by Alessandra Cipriani 24 Nov '15

24 Nov '15

With apologies for crossposting. -------- Original Message -------- Subject: PhD position in statistics of extremes From: Juan-Juan Cai <J.J.Cai(a)tudelft.nl> We are now recruiting a phd student for the project “Probabilistic forecasts of extreme weather utilizing advanced methods from extreme value theory”. Might you help to forward this to some candidates who might be interested? Thank you very much! For information about this position, see the end of the email or click here http://recruitment2.tudelft.nl/vacatures/index.php?lang=en&id=564779&type=a . Best, juan Duration of contract 4 years Salary scale €2125 to €2717 per month gross Job description The research project “Probabilistic forecasts of extreme weather utilizing advanced methods from extreme value theory” is funded by STW and is a collaboration between the statistics section, Delft University of Technology and the R&D Weather and Climate Modelling department of the Royal Netherlands Meteorological Institute (KNMI). There is an urgent need for statistically sound prediction methods for extreme weather, which often has a strongly disruptive societal impact. The PhD candidate will develop advanced statistical post-processing methods to estimate the probability of extreme weather, utilizing large meteorological data sets and extreme value theory, and will verify these newly developed methods. It is expected that the new statistical models will be used by several partners, including KNMI, to improve their short-term forecasts and warnings of extreme weather. The PhD candidate will work in close collaboration with colleagues from KNMI and communicate regularly with the partners on project progress. The student will be supervised by Prof. G. Jongbloed (TU Delft), Dr. J. Cai (TU Delft) and Dr. M.J. Schmeits (KNMI). The position includes modest teaching duties. The candidate is expected to finish his/her project with a PhD thesis and disseminate the results through publications in peer-reviewed journals and presentations at international conferences. Requirements The candidate possesses an MSc degree in mathematics (specialisation statistics or probability theory) or econometrics, preferably with a strong curriculum in extreme value theory. Some experience with handling and analysing large data sets would also be advantageous. (S)he must be highly motivated and interested in meteorology and have some experience in (statistical) programming (e.g. in R). In addition, we require very good communication skills and fluent spoken and written English. How to apply Applications should include a letter of application emphasising your specific interest in and qualifications for this position, a detailed CV, a publication list if applicable and contact details of at least two references. Additionally, a transcript of the course programmes attended and the grades obtained is required. Please e-mail your application by 15 December 2015 to Mrs. P.T.M. van den Bergh, Hr-eemcs(a)tudelft.nl . When applying for this position, please refer to vacancy number EWI2015-42. Information For more information about this position, please contact Dr. J. Cai ( J.J.Cai(a)tudelft.nl ) or Prof. G. Jongbloed ( G.Jongbloed(a)tudelft.nl ).

Seminario di Probabilità - Università di Padova
by Paolo Dai Pra 23 Nov '15

23 Nov '15

Ho il piacere di invitarvi al seguente seminario, che si terrà Lunedì 30 Novembre, alle 16:30, in Aula 1BC45 della Torre Archimede presso il Dipartimento di Matematica dell'Università degli Studi di Padova. SPEAKER: Alessandro Zocca AFFILIATION: TU Eindhoven TITLE: Hitting times asymptotics for hard-core interaction on finite graphs and applications to random-access networks ABSTRACT: We consider the hard-core model on finite graphs, which is a stochastic model for particles that dynamically interact in a finite volume subject to hard-core constraints. This model can be used to describe the dynamics of random-access networks, where, due to wireless interference, active users prevent other nearby users from simultaneous activity. In order to gain insight in the network performance and starvation phenomena, we examine the behavior of the first hitting times between maximum-occupancy configurations and mixing times. For this purpose it is convenient to look at the same model in the framework of Friedlin-Wentzell Markov chains with Metropolis transition probabilities. In this context, the high-fugacity regime in which we are interested corresponds to the low-temperature limit and the maximum-occupancy configurations are the stable states of the corresponding energy landscape. We will illustrate how we extended the pathwise approach beyond the classical metastability setting in order to study, for instance, the tunneling time between stable states. For some specific graphs of interest, e.g. grid graphs and triangular grid graphs, we will show by means of a novel combinatorial method how the order-of magnitude of the tunneling time between the two stable states depends on the size of the lattice and on the boundary conditions. After having discussed some applications of our results to random-access networks, we will then focus on the Widom-Rowlison model on finite graphs which, besides providing another example where our generalized framework can be used, is also instrumental to study multi-channel random-access networks. (This talk is based on joint work with Sem C. Borst, Johan S.H. van Leewaarden and Francesca R. Nardi) Paolo Dai Pra Dipartimento di Matematica Via Trieste, 63 35121 Padova Tel. +39 0498271361 Fax +39 0498271428 daipra(a)math.unipd.it <mailto:daipra@math.unipd.it>
