Outline of Final Research Achievements

In this research, econometric methods applicable to the model with possible structural breaks are analyzed. It was shown that the proper use of bootstrap methods improves the accuracy of the statistical tests for the existence of structural breaks. Also, it is indicated that the use of the so-called shrinkage estimators can produce predictions with higher performance even when the model with possible structural breaks are employed.
