The article argues that the rapid growth in a number of Asian economies tha
t occurred between 1960 and 1996 was accompanied by a major change in the s
tructure of their economies including shifts in the size of firms and the s
ectors of specialisation. These changes were a fundamental component of the
growth process. While capital accumulation was an important source of grow
th, its productive assimilation was a critical component of the success of
these economies. Estimates of the contribution of total factor productivity
to aggregate growth that neglect these phenomena may lead to erroneous est
imates.
