Measuring the sources of economic grow th in the EU with parametric and non-parametric methods
ENThe standard neoclassical growth accounting (parametric) framework serves to explain only a minor part of labour productivity growth and its crosscountry differences, thus implying an important role (as yet unexplained) for the Solow Residual or the Total Factor Productivity (TFP). However, the increased application of non-parametric methods in growth accounting, and in particular with Data Envelopment Analysis (DEA), has revealed that, along with the direct effect on output, a higher capital stock will have a substantial indirect effect that has been disregarded by the neoclassical framework. In line with an appropriate technology model (Basu, Weil, 1998), a higher capital stock allows a country to use a better technology. This paper extends the evidence regarding the relevance of an appropriate technology view to those Eastern European countries that were not previously included in a growth accounting investigation using non-parametric methods. It also reveals that the appropriate technology view is useful in explaining labour productivity growth and its cross-country differences within the EU. Furthermore, the results are robustly subject to assumptions on capital formation and on whether labour productivity has been adjusted with regard to the cross-country differences in employment structure by the various sectors and by natural resource endowment. Given both the direct and indirect effects of capital accumulation, it might prove to be a much more important tool for determining labour productivity growth than is usually considered within a neoclassical framework.
