Seminario RINOTT
by Matteo Ruggiero 26 Apr '19

26 Apr '19

STATISTICS SEMINARS @ COLLEGIO CARLO ALBERTO Venerdì 3 Maggio 2019, alle ore 12:00, presso il nuovo edificio del Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ Yosef RINOTT (Hebrew University of Jerusalem) MONOTONICITY OF CONVERGENCE OF POSTERIORS, AND TURAN TYPE INEQUALITIES Given a prior distribution on a space of states of nature, suppose we quantify our belief a given state is by computing its posterior probability having received a signal. If the signal arises under the same (true) state, does it always boost our belief that this is indeed the true state, and when it does, in what sense? What happens to this belief given a signal distributed according to a different state? Given a sequence of iid observations, the posterior probability of a parameter, when the data are generated according to the same parameter, converges to one, and to zero when the data are generated by another value of the parameter. We study monotonicity and unimodality properties of this convergence including stochastic orderings between prior and posterior, and monotonicity of the expected posterior. Some of the results apply to very general settings, and in others we focus on coin tossing. It turns out that there is a relation to Turan’s inequality for orthogonal polynomials, and in particular, to Legendre polynomials. ------------------------------------------------ Tutti gli interessati sono invitati a partecipare. Il seminario è organizzato dalla "de Castro" Statistics Initiative (www.carloalberto.org/stats) in collaborazione con il Collegio Carlo Alberto. Cordiali saluti, Matteo Ruggiero --- Matteo Ruggiero University of Torino and Collegio Carlo Alberto www.matteoruggiero.it

Seminario L. Campi - Verona
by Alessandro Gnoatto 18 Apr '19

18 Apr '19

AVVISO di SEMINARIO 24 April 2019 at 14.00 - Polo Santa Marta, Via Cantarane 24, Sala Vaona (Room 1.59) Speaker: Luciano Campi (London School of Economics) Title: Optimal market making under partial information with general intensities Abstract: Starting from the Avellaneda--Stoikov framework, we consider a market maker who wants to optimally set bid/ask quotes over a finite time interval, to maximize her expected utility. The intensities of the orders she receives depend not only on the spreads she quotes, but also on unobservable factors modelled by a hidden Markov chain. We tackle this stochastic control problem under partial information with a model that unifies and generalizes many existing ones, combining several risk metrics and constraints, and using general decreasing intensity functionals. We use stochastic filtering, control and piecewise-deterministic Markov processes theory, to reduce the dimensionality of the problem and characterize the reduced value function as the unique continuous viscosity solution of its dynamic programming equation. We then solve the analogous full information problem and compare the results numerically through a concrete example. We show that the optimal full information spreads are biased when the exact market regime is unknown, and the MM needs to adjust for `regime risk' in terms of liquidity volatility and sensitivity to regime changes. This effect becomes higher the longer the waiting time in between orders. The talk is based on a joint paper with D. Zabaljauregui (LSE). -- Prof Alessandro Gnoatto, PhD Dipartimento di Scienze Economiche Università degli Studi di Verona Via Cantarane 24 37129, Verona, Italy Room 1.05 Tel: +39 045 802 8537 Homepage: www.alessandrognoatto.com<http://www.alessandrognoatto.com> E-mail: alessandro.gnoatto(a)univr.it<mailto:alessandro.gnoatto@univr.it> -------------------------------------------------- View my research on my SSRN Author page: http://ssrn.com/author=1615989 --------------------------------------------------
