Measuring Technical Change and Productivity Growth with Varying Output Qualities
and Incomplete Panel Data par Georges Dionne and Robert Gagné
This paper presents a method for estimating technical change using incomplete panel data. In addition, we show how estimates of cost elasticities with respect to output qualities can be used to evaluate productivity growth adjusted for quality changes. In order to control for the incomplete nature of the sample used, specific dummy variables for entry in and exit from the sample are introduced into the cost function. The proposed methodology is applied to an unbalanced sample of trucking firms from Quebec. Results show that without correction for sample entry or exit, the estimated rate of technical change between 1987 and 1988 is -29,7%. When entry in or exit from the sample is taken into account, the estimated rate is -4,2%. Also, during the same period, the observed TFP growth rate is 63.4%. After adjustment for quality changes, this rate falls to -4,6%. Source : Éditeur (via Persée) |
