prof Campi's seminar - LUISS June 7
by Sara 04 Jun '18

04 Jun '18

On June 7, at 12 pm room 305B prof Luciano Campi, the London School of Economics, will give the following seminar Title: N-player games and mean field games with absorption Abstract: We introduce a simple class of mean field games with absorbing boundary over a finite time horizon. In the corresponding N-player games, the evolution of players' states is described by a system of weakly interacting Ito equations with absorption on first exit from a bounded open set. Once a player exits, her/his contribution is removed from the empirical measure of the system. Players thus interact through a renormalized empirical measure. In the definition of solution to the mean field game, the renormalization appears in form of a conditional law. We justify our definition of solution in the usual way, that is, by showing that a solution of the mean field game induces approximate Nash equilibria for the N-player games with approximation error tending to zero as N tends to infinity. This convergence is established provided the diffusion coefficient is non-degenerate. The degenerate case is more delicate and gives rise to counter-examples. The talk is based on a joint paper with Markus Fischer (Padua University). best regards -- Sara Biagini, Professor of Mathematical Finance Department of Economics and Finance LUISS Guido Carli Address: viale Romania, 32 - 00197 Roma Web: http://sites.google.com/site/sarabiagini/

On Global Optimization of the Likelihood Function for Linear Time Series Models *Tuesday 5 June 2018* *Venue:* Department of Mathematics, via Sommarive, 14 - Povo (TN) - Seminar Room "-1" *At: *4:30 pm Speaker: - *Bernard Hanzon* (Dept Mathematics, University College Cork, Ireland) *Abstract:* We present an approach to find the global optimum of a linear time series model in state space form. By firstly applying a partial optimization step to the likelihood function the problem can be reduced to a problem of optimization of the likelihood over a set which has compact closure. By applying a regularization the resulting problem is that of finding the optimum of a Lipschitz continuous function on a compact set which is known to have a (constructive) solution. Techniques from the theory of parametrization of linear state space systems and some basic techniques from differentiable manifold theory are used to obtain these results. Furthermore the surprising fact is shown that the "crude" maximum likelihood estimator (without regularization and compactification) does not exist in the sense that the likelihood function has an infinite, typically unattained, supremum. Comments will be made about the effect of the regularization used on the outcome. *Contact person: *Stefano Bonaccorsi

The game features strategic substitutability for low existing leverage and one-sided strategic complementarity for high existing leverage. The resulting leverage process exhibits a mean-reverting regime around a long-run level, as long as it stays below an instability level. Above the instability level, leverage becomes explosive. We validate our model empirically using aggregate returns of financial firms over the 10 year period 2001-2010. Our model predicts the leveraging/deleveraging of this period, and in particular the 2008 collapse in short term debt. *Dipartimento di Economia e Finanza* Viale Romania, 32 - 00197 Roma <https://maps.google.com/?q=Viale+Romania,+32+-+00197+Roma&entry=gmail&sourc…> *def(a)luiss.it <def(a)luiss.it>* t +39 06 85225550 <06%208522%205550> *www.luiss.it <http://www.luiss.it/>* [image: http://static.luiss.it/images_10/loghi/LS_BLU_RIDUZIONE_WEB.png] Il tuo 5x1000 alla LUISS: C.F. 02508710585 <02%205087%2010585> [image: http://www.luiss.it/images_10/icons/environment-icon.png] *Please consider the environment... do you really need to print this email?* -- Sara Biagini, Professor of Mathematical Finance Department of Economics and Finance LUISS Guido Carli Address: viale Romania, 32 - 00197 Roma Web: http://sites.google.com/site/sarabiagini/
