(eng): The main visual feature of Slovak unemployment data is a dramatic increase after the elections in October 1998 which can be expressed by a step in the deterministic level function. In the residuals from this level function we can identify a significant cyclical component and a long memory structure (with the estimated value of the Hurst parameter close to 0.8) as well as an autoregressive short memory behaviour.

(cze): Dramatický růst po volbách v roce 1998 je nápadným rysem údajů o nezaměstnanosti na Slovensku. V reziduu deterministické úrovňové funkce, která tento růst modeluje, je možné zjistit významnou cyklickou složku a dlouhodobou paměťovou strukturu, jakož i krátkodobou regresi.
