Credit scoring models that rely on logistic regression have been the most widely applied to evaluate credit risk, more specifically to analyze the probability of default of a borrower when a credit contract initiates. However, these methods have some limitations, such as the inability to model the entire probabilistic structure of a process, namely, the life of a mortgage, since they essentially focus on binary outcomes. Thus, there is a weakness regarding the analysis and characterization of the behavior of borrowers over time and, consequently, a disregard of the multiple loan outcomes and the various transitions a borrower may face. Therefore, it hampers the understanding of the recurrence of risk events. A discrete-time Markov chain model is applied in order to overcome these limitations. Several states and transitions are considered with the purpose of perceiving a borrower’s behavior and estimating his default risk before and after some modifications are made, along with the determinants of post-modification mortgage outcomes. Mortgages loans are considered in order to take a reasonable timeline towards a proper assessment of different loan performances. In addition to analyzing the impact of modifications, this work aims to identify and evaluate the main risk factors among borrowers that justify transitions to default states and different loan outcomes.Damásio, Bruno Miguel PintoRUNAlmeida, Filipa Cardoso de2020-06-19T11:47:41Z2020-06-162020-06-16T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10362/99608TID:202486818enginfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2024-03-11T04:46:28Zoai:run.unl.pt:10362/99608Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-20T03:39:13.645522Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
