Economic Growth: A Channel Decomposition Exercise


  • Wong Wei-Kang

    () (National University of Singapore)


This paper empirically decomposes the channels through which the determinants of growth operate. Methodologically, channel decomposition combines growth accounting with regression analysis. Under channel decomposition, the determinants could affect aggregate productivity growth through physical capital accumulation, through human capital acquisition, or through growth in total factor productivity (TFP). The results from channel decomposition show that TFP growth is the main channel of operation for most of the determinants. Specifically, TFP growth, not factor accumulation, is what accounts for conditional convergence. This finding is extremely robust. There is also no evidence that rich and poor countries converge through different channels.
