Seminario Karim Barigou in Bicocca
by Valeria Bignozzi 06 Feb '20

06 Feb '20

Si avvisa che il giorno Lunedì 10 Febbraio alle ore 15:30 presso l’Università di Milano-Bicocca (via degli Arcimboldi 8 - edificio U7, quarto piano- aula 4026) si terrà il seguente seminario: Speaker: Karim Barigou (University of Lyon) Title: Fair valuation of insurance liabilities: interplay between actuarial judgement and market-consistency Abstract: Insurance liabilities are in most cases (only) partially replicable by traded assets. This may be due to the fact that the payoffs of the underlying insurance contracts are defined in terms of a combination of hedgeable and unhedgeable claims (e.g. unit-linked insurance) or due to the existence of traded insurance-linked securities of which the payoff is correlated with the payoff of the insurance liability (e.g. CAT bonds). Since not all insurance claims can be perfectly replicated by traded assets, we face the problem of valuating claims in incomplete markets (i.e. markets in which some claims are not perfectly hedgeable). The main goal of this presentation is to introduce different valuation frameworks for the determination of a fair valuation for insurance liabilities. The objective of this valuation is to merge the traditional actuarial valuation based on pooling and diversification with a market-consistent approach based on hedging and replication. In particular, we define a fair valuation as a valuation which is market-consistent (marked-to-market for hedgeable claims) and actuarial (marked-to-model for claims independent of financial market evolutions). Among the different fair valuation frameworks, we introduce and investigate the class of `hedge-based valuations'. Under this approach, one unbundles the unhedgeable insurance claim in a hedgeable part and a remaining part. The fair value of the claim is then set equal to the sum of the respective values of the hedgeable and the unhedgeable parts, where the hedgeable part is valuated by the financial price of its underlying hedge, while the value of the remaining part is determined via an actuarial approach. Tutti gli interessati sono invitati a partecipare.

Ricevo e inoltro per potenziali interessati. ---------- Forwarded message --------- Subject: Fwd: [forumppg] XXIV Brazilian Probability School /São Paulo School of advanced science Date: 2020-02-04 12:02 From: Patrícia Gonçalves <mophinha(a)gmail.com> To: Chiara Franceschini <chiara.franceschini(a)tecnico.ulisboa.pt> Can you distribute this in Italy? Thanks! ---- *XXIV EBP/ São Paulo School of advanced science on singular stochastic partial differential equations and their applications* It is a pleasure to announce the XXIV EBP/ São Paulo School of advanced science on singular stochastic partial differential equations and their applications. The São Paulo school is divided into two parts and will happen in the weeks of July 28 to August 8, 2020 at Campinas University. In the first week there will be two introductory mini courses (stochastic calculus and rough paths) that lay the foundations for the courses of the second week. In the latter ones newly developed theories and their latest developments in the field of singular SPDEs and related areas will be taught. The program will be complemented with several plenary talks, invited talks, a poster session and a visit to the LNLS laboratories, where the only particle accelerator of Latin America is located. The school will give full financial support for around 100 students (50 from Brazil and 50 from abroad). More informations under https://www.ime.unicamp.br/spas2020/ . The XXIV EBP will coincide with the second week of the São Paulo School. As in previous years, the XXIV EBP will consist of two mini courses, plenary talks, contributed talks and poster sessions, all presented in a relaxed atmosphere. This will be our first edition at IMECC-UNICAMP, which is home to one of Brazil's top ranked Mathematics departments. More information under https://www.ime.unicamp.br/bsp2020/. We would be grateful if you could advertise these events among your colleagues.

Seminar Fabrizio Leisen @ Unimib
by Federico Camerlenghi 03 Feb '20

03 Feb '20

Dear all, we are glad to announce the next DEMS seminar: Wednesday, 12th February 2020 Time 12.00, Aula de Lillo, Department of Economics, Management and Statistics (DEMS) Building U7, II floor, University of Milano - Bicocca The speaker is Fabrizio Leisen from University of Kent. *Title:* *On a Class of Objective Priors from Scoring Rules* *Abstract:* Objective prior distributions represent an important tool that allows one to have the advantages of using a Bayesian framework even when information about the parameters of a model is not available. The usual objective approaches work off the chosen statistical model and in the majority of cases the resulting prior is improper, which can pose limitations to a practical implementation, even when the complexity of the model is moderate. In this talk we propose to take a novel look at the construction of objective prior distributions, where the connection with a chosen sampling distribution model is removed. We explore the notion of defining objective prior distributions which allow one to have some degree of flexibility, in particular in exhibiting some desirable features, such as being proper, or log-concave, convex etc. The basic tool we use are proper scoring rules and the main result is a class of objective prior distributions that can be employed in scenarios where the usual model based priors fail, such as mixture models and model selection via Bayes factors. In addition, we show that the proposed class of priors is the result of minimising the information it contains, providing solid interpretation to the method. This is a work in collaboration with C. Villa and S. G. Walker.
