The Faculty of Informatics is pleased to announce a seminar given by Paolo Giudici



Network models to improve credit risk estimation
Speaker: Paolo Giudici
University of Pavia, Italy
Date: Monday, October 15, 2018
Place: USI Lugano Campus, room SI-006, Informatics building (Via G. Buffi 13)
Time: 13:30-15:15



We propose credit risk measurement models that incorporate not only idiosyncratic risk, as measured by credit ratings or CDS spreads, but also how companies and countries interact via multiple linkage types. The models are based on network science methods that extract adjacency matrices from multilayer networks,based on financial transactions  between companies and/or countries. Based on an adjacency matrix, we develop new network centrality measure that can employed to correct traditional credit risk measures, taking contagion into account. The proposed methodology will be applied to different contexts. First, we will employ the Bank of International Settlements statistics that describe financial flows between country banking systems, and show how credit risk of a country (sovereign risk) can be affected by contagion from other countries, either on the funding or on the lending side. Then we will consider the context of financial technology (fintech)  and, specifically, that of peer-to-peer lending. We will show that including network parameters does improve the accuracy of the credit risks estimated by peer to peer lenders and, in addition, provides useful information on the variables that emphasize the centrality of bad performing companies, potentially triggering contagion.


This talk is part of a public seminar series organised within the Master in Financial Technology & Computing
