Private Information, Credit Risk and Graph Structure in P2P Lending Networks

source A new working paper investigated the potential for improving P2P credit scoring by using “private information” about communications and travels of borrowers. The main finding is that P2P borrowers’ ego networks exhibit scale-free behavior driven by underlying preferential attachment mechanisms that connect borrowers in a fashion that can be used to predict loan profitability.

Graph topology was found to be an important predictor of loan profitability, explaining over 5.5% of variability. Networks of borrower location information explain an additional 19% of the profitability. Machine learning algorithms were applied to the data set previously analyzed to develop the predictive model and resulted in a 4% reduction in mean squared error.
