Convergence patterns in income and manufacturing productivity in EU: does the latter drive the former?

Abstract

ABSTRACT While exploring convergence in real income and in manufacturing productivity of the central and eastern European countries (CEE) and the southern EU counties with the developed EU ones, testing and clustering methodology and sigma convergence are used. We found that CEE countries strongly converge, both in real income and manufacturing productivity, with developed EU countries, while the southern EU countries do not. Moreover, the convergence pattern in real income follows that in manufacturing productivity in both peripheral EU groups suggesting that the underlying productivity clubs determine the formation of income clubs. The observed time pattern of sigma convergence also suggests that manufacturing productivity drives economic growth, as (non)convergence of the former preceded (‘caused’) that of the latter. Aforementioned findings are robust, since they are supported by the results obtained both by the Phillips and Sul (2007) approach and sigma convergence.
