Decomposing TFP Growth in the Presence of Cost Inefficiency, Nonconstant Returns to Scale, and Technological Progress

Abstract: Productivity growth is a major source of economic growth; thus, an understanding of how and why productivity measures change is of great interest to economists and policymakers. This paper explores the relationship between observed total factor productivity (TFP) growth, defined using an index number approach, and examines changes in returns to scale, cost efficiency, and technology. Several decompositions are developed, using alternatively production and cost frontiers. The last decomposition developed also a… Show more

“…Both Bauer (1990) and Kumbhakar and Lovell (2000) have shown that TFP growth composes of technical progress, technical efficiency change and a scale economies effect. In theory, technical progress is an outward shift of the production frontier and technical efficiency change shows the movement from a position within towards a position on the production frontier, while the scale economies effect reflects an increase in return to scale.…”

“…In the case of a logarithmic production function, following Denny et al (1981) and Bauer (1990), the Divisia index of total factor productivity (TFP) growth can be defined as the growth in scalar output (y = f(x,t;α)), which cannot be explained by the growth in the input quantity index (vector X) over time (t):…”

“…The author decomposes total factor productivity growth into scale economies, technical change, and efficiency change, based on longitudinal data from 34 U.S. investor-owned electric utilities and using the Bauer (1990) method combined with techniques developed by Denny, Fuss, and Waverman (1981) and Granderson (1997). He identifies the productive contribution of the bad output using methods developed by Ball, Fare, Grosskopf, and Zaim (2005) and Chapple, Morrison Paul, and Harris (2005).…”
