This paper reviews approaches to the measurement of total factor productivity, efficiency and technological change. Nonfrontier analysis assumes that the production technology is efficient and technological change is equivalent to total factor productivity change. On the other hand, the frontier approach explicitly considers inefficiency of production. In the presence of inefficiency, total factor productivity consists of efficiency and technological change. The traditional parametric approach to technological change may give results with technological bias that are sensitive to a specific parametric form applied in the analysis. The advantage of the nonparametric frontier approach using Data Envelopment Analysis in productivity analysis has been recently recognized. The Malmquist productivity index (Fare, Grosskopf, Kindgren and Ross, 1989) as a nonparametric frontier approach, is not constrained by specific functional forms and has shown a relative advantage in productivity analysis in developing countries where price information is limited and only quantity data is available. The Malmquist productivity index can be decomposed into efficiency change and technological change, which can provide useful information for policy analysis.
