The article discusses the importance of potential GDP in macroeconomic analysis and forecasting, as well as its unique role. In particular, the estimation of potential GDP by time series methods will determine the pattern of change of potential GDP over time. Potential GDP estimated based on time series methods can be used mainly to obtain general information about the trend of potential GDP or to compare it with potential GDP based on another approach. The frequency and time interval will partly depend on the purpose of using the potential GDP. At the same time, an econometric analysis of potential GDP was carried out.
