摘要：We investigated different take-up rates of home loans in cases in which banks offered different interest rates.If a bank can increase its take-up rates, it could possibly improve its market share.In this article, we explore empirical home loan price elasticity, the effect of loan-to-value on the responsiveness of home loan customers and whether it is possible to predict home loan take-up rates.We employed different regression models to predict take-up rates, and tree-based ensemble models (bagging and boosting) were found to outperform logistic regression models on a South African home loan data set.The outcome of the study is that the higher the interest rate offered, the lower the take-up rate (as was expected).In addition, the higher the loan-to-value offered, the higher the take-up rate (but to a much lesser extent than the interest rate).Models were constructed to estimate take-up rates, with various modelling techniques achieving validation Gini values of up to 46.7%.Banks could use these models to positively influence their market share and profitability.
