Productivity growth and biased technological change in UK airports

In this paper we estimate the total factor productivity of UK airports using a Malmquist index. Productivity change is factored into an index of efficiency change and an index of technological change. Technological change is further decomposed into indexes that measure the bias in the production of outputs, the bias in the employment of inputs, and the magnitude of the shift in the production frontier, Airports are ranked according to their productivity change for the period 2000-2005. Economic implications are derived. (C) 2009 Elsevier Ltd. All rights reserved.
