摘要:This paper examines the homogeneity of the OECD member states in 1996. Besides the free-market industrialized countries the database contains the Czech Republic, Hungary and Poland, as three new members of the Organization for Economic Cooperation and Development (OECD). International comparison is conducted on the basis of general income indicators, among them the GDP per capita using current exchange rates and current purchasing power parities (PPP). Investigating the effect of the GDP level and of taxation on disposable income and on final consumption in the OECD countries, present paper deals with the statistical similarity of members. Different classifications of countries are presented using multivariate statistical procedures (cluster analysis and multidimensional scaling).
