Seminario Maren Schmeck a Padova
by Tiziano Vargiolu 27 Feb '17

27 Feb '17

Carissimi, il giorno martedi' 28 febbraio alle ore 15 presso il Dipartimento di Matematica dell'Universita' di Padova, via Trieste 63, sala Riunioni VII piano, la dott.ssa Maren Diane Schmeck dell'Universita' di Colonia terra' un seminario dal titolo ELECTRICITY PRICE MODELING WITH STOCHASTIC TIME CHANGE (joint with SVETLANA BOROVKOVA (VU AMSTERDAM)) ABSTRACT. In this paper, we develop a novel approach to electricity price modeling, based on the powerful technique of stochastic time change. This technique allows us to incorporate the characteristic features of electricity prices (such as seasonal volatility, time varying mean reversion and seasonally occurring price spikes) into the model in an elegant and economically justifiable way. The stochastic time change introduces stochastic as well as deterministic (e.g., seasonal) features in the price process? volatility and in the jump component. We specify the base process as a mean reverting jump diffusion and the time change as an absolutely continuous stochastic process with seasonal component. The activity rate of the stochastic time change can be related to the factors that influence supply and demand. Here we use the temperature as a proxy for the demand and hence, as the driving factor of the stochastic time change, and show that this choice leads to realistic price paths. We derive properties of the resulting price process and develop the model calibration procedure. We calibrate the model to the historical EEX power prices and apply it to generating realistic price paths by Monte Carlo simulations. We show that the simulated price process matches the distributional characteristics of the observed electricity prices in periods of both high and low demand.

Mini course in Verona - Simone Mattia Scotti: Real markets, microstructure, clusters and Hawkes with a Branching process point of view.
by Luca di persio 20 Feb '17

20 Feb '17

*Mini course announcement* Prof. Simone Mattia Scotti [ LPMA, Université Paris Diderot ] will give a mini course on *Real markets, microstructure, clusters and Hawkes with a Branching process point of view*, according with the following time table: 21st of March (2017) : Room I 1430-1730 23rd of March (2017) : Room M 1530-1730 24th of March (2017) : Room M 1430-1730 all the lessons will take place at the Dept. of Computer Science - UniVr Strada le Grazie, 15 - Verona Ca' Vignal located here https://goo.gl/maps/Yx2JU *Abstract and structure of the course* The analysis of real financial markets, along with the study of related economic time series, represents an increasing field of research and development of effective applications, from the stochastic processes point of views, as well as from the statistic and computational sides of the moon. In this mini-course, we first recall the classical framework behind the modern and mathematically rigorous, theory of finance, starting from the treatment of continuous-path stochastic processes. Then, we focus on the microstructure of market data, discussing both limit and market orders, along with correlated liquidity problems. In a second part, we will specialize our analysis on a particular feature of financial markets, namely the existence of jumps' cluster. It is worth to mention that the latter has been highlighted in recent literature in microstructure, showing to have a deep impact on real markets and representing a main research axis in the field. >From a mathematical point-of-view, we will first introduce point processes and then Hawkes processes. We will show that the self-exciting structure of Hawkes processes can easily explain some features exhibited by financial data, e.g. the cluster effects. In the third part, we will introduce the branching processes (CBI) showing that they can be seen as a natural extension (marked versions) of Hawkes processes. We will show that this class of models has very nice properties from computational as well as from analytical point of view, particularly by exploiting the Dawson-Li representation. Moreover, we will point out some unexpected features of the aforementioned approaches, such, e.g., the persistency of low interest rates and negative risk premium in electricity markets. A detailed bibliograpy will be given during the course. ___________ Do not hesitate to contact me for further details: luca.dipersio(a)univr.it LuCa -- __ Luca Di Persio - PhD assistant professor of Probability and Mathematical Finance Dept.

Mini course in Verona - Adrian Zalinescu : Introduction to SPDEs with applications
by Luca di persio 18 Feb '17

18 Feb '17

*Mini course announcement* Prof. Adrian Zalinescu [ Universitatea Alexandru Ioan Cuza - Iaşi, Romania ] will give a mini course on *Introduction to Stochastic Partial Di fferential Equations* (with applications to Finance, Biology, etc.), according with the following calendar 13 - 20 - 27 of March (2017) time table: from 1430 to 1730 all the lessons will take place at the Dept. of Computer Science - UniVr Strada le Grazie, 15 - Verona Ca' Vignal 2, first floor , *Room M* located here https://goo.gl/maps/Yx2JU The* tentative programme* is the following: 1. *Gaussian measure theory* Random vectors and Bochner integral. Some elements of probability in in nite-dimensional spaces are considered, with emphasis on the integration of random vectors with values in separable Banach-spaces and in operator spaces. Gaussian measures. We introduce cylindrical Gaussian random variables and Hilbert-spacevalued Gaussian random variables and then de ne cylindrical Wiener processes and Q-Wiener processes (i.e. with the covariance given by the trace-class operator Q) in a natural way. Stochastic integral and Ito's formula. The stochastic integral is constructed with respect to a cylindrical Wiener process, then with respect to a Q-Wiener process, by extending the integral of elementary processes. Some properties of the stochastic integral are given, including Ito's formula. 2. *Stochastic Di erential Equations* Semigroup Theory. In this section we review the fundamentals of semigroup theory. Stochastic Convolutions and Linear SPDEs. We derive existence and uniqueness of di erent types of solutions for linear SDEs driven by generators of C0-semigroups. The method is based on the study of the stochastic convolution. Solutions by Variational Method. The purpose is to study solutions of nonlinear SPDEs, which are seen as evolution equations in a Gelfand triplet, under assumptions of compact embedding or monotone coe cients. 3. *Applications* Along the abstract study of SDEs in in nite-dimensional spaces, various examples of SPDEs with applications in physics, biology and mathematical finance will be given. A detailed bibliograpy will be given during the course. ___________ Do not hesitate to contact me for further details: luca.dipersio(a)univr.it LuCa __ Luca Di Persio - PhD assistant professor of Probability and Mathematical Finance Dept.
