The Similarity of the Changes in Average Transaction Prices of 1 m2 of Housing in Selected Cities of Silesia

The paper provides a statistical analysis of behaviour of average transaction prices of 1m2 of apartment space on local markets in the Silesian Voivodeship. The conducted research reveals that time and space analogies occur on local apartment markets in this voivodeship, i.e. the similarity of behaviour of transaction price changes with time. The shape similarity measure was applied for evaluating the degree of similarity and identifying the amount of lags. It enabled distinguishing leading, convergent and imitating markets among the analysed apartment markets. There was analysed also if the phenomenon of sigma convergence or sigma divergence occurs among local markets. Sigma convergence in the period of 1Q2006 - 1Q2009 and the stabilization in the period of 2Q2009 - 2Q2011 was stated
