| Summary | The purpose of this paper is to attempt to measure biases in the technological change of an airport over a period of time. This study is divided into two stages. The first stage involves the construction of Tornqvist indices. Indices for three output groups and three input groups are constructed and discussed. Index of total factor productivity is also constructed. In the second stage, we adopt a dual approach to production function to investigate possible biases in the rate of technological change between inputs and outputs. The Generalized McFadden profit functional form is used. In the case of C. K. S. Airport, the measures of biases in technological change suggested that materials and services were Hicks-using relative to the other input groups. It is different from the results of Tornqvist TFP. The measures of biases for the outputs indicate that movements had experienced faster technological growth than passengers and non-aeronautical revenue. In conclusion, we use a non-parametric index number approach to illustrate how such a global measure can be used to investigate airport productivity, and a parametric duality function method to measure biases in the technological change that often are very useful to airport managers and to those monitoring airport operations. |
