Regional Growth And Unemployment. The Validity Of Okun's Law For The Finnish Regions
This paper offers a concise critical overview of Okun's Law, with particular attention for its relevance in open economic systems of regions. Based on an extensive set of economic data for Finnish regions, the existence of cointegration is tested by using alternative statistical methods, viz. the residual-based test and the conditional error correction model. A novelty of the paper is to combine a method of hidden cointegrations with a method of removing cross-sectional dependence. After correcting for hidden cointegrations and cross-sectional dependence, both statistical methods used yield almost similar results and confirm cointegration for the relevant data on Finnish regions.
