Abstract [en]

The purpose of this thesis was to examine the Swedish electricity price in order to determine whether there are any structural breaks in the time series. Both the nominal and the real price of electricity under the period 1900 to 2006 are examined. The theoretical framework used in this thesis is different tests for unit root and structural breaks in time series. Tests for both exogenously and endogenously determined breaks are performed. Different quantitative methods for measuring structural breaks are applied in order to compare any differences. The results showed that both the nominal and real electricity price exhibits unit root and that breaks are most likely to occur rapidly. Both series exhibits a break around 1945 a time when the Swedish economy was growing and the demand for electricity was increasing. The results implies that more than one test should be used and compared when testing for structural breaks in time series.
