- W4200016421 abstract "We propose estimating a model for Loss Given Default (LGD) that allows accounting for spatial dependence between peer-to-peer (P2P) loans. We suggest the LGD two-stage approach with the Gaussian Markov Random Field model in each stage to represent the spatial variations. In the first stage, we predict total loss and no loss using two binary additive models with a flexible parametric link function given by the Generalised Extreme Value (GEV) distribution. In the second stage, we consider a beta regression in the Generalised Additive Model for Location Scale and Shape (GAMLSS) framework. The main advantage of our proposal is to provide accurate calibrated region-specific LGD estimates. We apply this model to a comprehensive dataset on P2P loans provided by Lending Club. The GEV link function better fits the data than the logit function in the first stage. The most important finding for financial institutions’ risk assessment is that including spatial effects and using a two-stage approach provide conservative estimates of the expected shortfall. • We suggest a flexible two-stage Loss Given Default model with spatial effects. • Spatial effects improve the predictive accuracy of the Loss Given Default model. • The proposed approach provides more conservative estimates of the expected shortfall." @default.
