Predicting Banking Crises with Artificial Neural Networks: The Role of Nonlinearity and Heterogeneity
构建基于人工神经网络的银行危机早期预警系统,利用国际数据集并考虑区域异质性,在24个月预测期内成功识别所有测试集危机,且神经网络优于传统逻辑回归。
Abstract Studies of the early warning systems (EWSs) for banking crises usually rely on linear classifiers, estimated with international datasets. I construct an EWS based on an artificial neural network (ANN) model, and I also account for regional heterogeneity in order to improve the generalization ability of EWS models. All of the banking crises in my test set are then predictable at a 24‐month horizon, using information from earlier crises. For some countries, estimation with a regional dataset significantly improves the predictions. The ANN outperforms the usual logit regression, assessed by the area under the receiver operating characteristics curve.
