Identyfikacja nieciągłości dynamiki PKB za pomocą analizy falkowej
Identification of the GDP dynamic discontinuity using wavelet analysis

Summary/Abstract: A comprehensive analysis is important for economic politics. The wavelet analysis has been used to detect discontinuities in analyzed GDP dynamic, where they are non-detectable by other signal analysis tools or invisible. This made possible to distinguish discrete moments of economic dynamic changes. To the most significant change moments in Polish economy belong: fourth quarters 1990 and 1991, the turn of the years 1993–1994, the second half-year 1995, first and fourth quarters 1996, the second quarter 2004, second and fourth quarters 2008.
