Abstract
- In the age of globalization, international loans and sovereign default probabilities have become one of the main topics of finance. Many severe economic crises have occurred on financial markets in the last decades. Therefore, the problem of measuring countries' default probabilities due to their external debt obligations has attracted the interest of many researchers. In recent literature there are many studies that use quantitative methods and machine learning techniques to predict countries defaults. Past studies on sovereign default prediction used many statistical and non-statistical approaches (machine learning), such as: logistic regression (two and more stages), discriminant analysis, support vector machines (SVM), neural networks, Bayesian models, classification trees, MARS (Multivariate Adaptive Regression Splines) and many more. In the recent years, in order to increase the classification efficiency of proposed models, the so-called ensemble classifiers are used. These techniques involve a combination of different methods and classifiers to significantly improve the effectiveness of models in assessing the prediction of bankruptcy or default on a loan. This paper presents the results of own research on the possibility of applying ensemble classifiers technique to international debt credit risk assessment for EU countries. The effectiveness of ensemble methods will be compared to some classic bankruptcy risk assessment methods. The ensemble model of sovereign default prediction was estimated in the 3-year forecast horizon and their efficiency was compared to certain individual models. The historical events of sovereign defaults come from Bank of Canada CRAG sovereign defaults database. The financial ratios used as predictors of internal debt defaults were estimated from the statistics of International Monetary Fund and World Bank databases. The estimated model will be used in sovereign default predictions for EU countries in year 2017. [ABSTRACT FROM AUTHOR]
