Technical efficiency measure can be classified as either radial or nonradial. While the theoretical question of which is the better type of measure is unresolved, the radial measures enjoy much greater popularity than the nonradial measures in the empirical literature. To assess the impact of...

This paper provides a comprehensive survey of the literature on production and cost frontiers for public transit operators, and it evaluates the contributions of frontier analysis to the understanding of the performance of the public transport sector. The authors first succinctly contrast best...

The purpose of this paper is to investigate the sensitivity of a recently proposed non-parametric approach to technical efficiency measurement. Using a data set of Belgian municipalities, we analyze the sensitivity of the Free Disposal Hull (FDH) approach with respect to the number of input and...

This paper explores a selection of recently proposed bootstrapping techniques to estimate non-parametric convex (DEA) cost frontiers and efficiency scores for transit firms. Using a sample of Norwegian bus operators, the key results can be summarised as follows: (i) the bias implied by...
