Simple and intuitive non-parametric methods are provided for estimating variance change points for time series data. Only slight alterations to existing open-source computer code applying CUSUM methods for estimating breakpoints are required to apply our proposed techniques. Our approach,...

The paper is the first attempt to analyse the impact of debt on economic growth in the context of Indonesia by combining the application of wavelet and non-linear techniques. Our results tend to indicate that there are complex lead-lag dynamic interactions between external debt-to-GDP ratio and...

In the paper the Haar wavelet transfer function models are suggested as a way to parsimoniously parametrise the impulse responses and construct models with parameters providing an insight into the frequency content of the relationships under scrutiny. Besides, the models enable to verify...
