Output & Productivity Growth Decomposition: A Panel Study of Manufacturing Industries in India

This paper decomposes output and productivity growth of thirteen 2-digit manufacturing industries as well as total manufacturing industry in India during 1981-82 to 2010-11. The four attributes of output growth are input growth, adjusted scale effect, technological progress and technical efficiency growth. A stochastic frontier model with a translog production function is used to estimate the growth attributes of the manufacturing industries. The results show that input growth is the major contributor to output growth whereas total factor productivity growth (TFPG) sometimes remains inadequate even though it has a positive and significant effect on output growth. Technological progress is found to be the major contributor to TFPG and the scale effect has become important during recent years.
