Sources of Economic Growth

The Two-Deflator Growth Accounting Approach (TDA)is a new methodology that is based on the theory of capital, not on the theory of production as in the traditional growth accounting approaches. It is superior to the traditional approach in many ways. The measurement of growth at the disaggregated level can resolve many macroeconomic issues which are not possible in an aggregated framework. There are three main outcomes of this study; first, human capital quality upgrade contribution to labor growth is separated successfully by the TDA and it is negatively correlated to TFP growth; second, value added growth is mainly explained by the growth of capital stock and TFP growth; and third, TFP growth is not homogeneous and may occur in any industry/firm at any time. The contribution of raw labor in value added growth in public manufacturing industries is more significant than the maintenance and quality upgrade components of human capital. It is observed that the productivity growth of public labor is lower than in the private sector.
