An evaluation of yardstick regulation for European airports

The European airport industry is subject to various forms of economic regulation and there is debate as to which of the systems provides the best incentives for allocative and productive efficiency. This paper deals with the applicability of benchmarking as a regulatory tool for airports. This form of regulation aims at evaluating the cost level of a firm by comparing it to the mean marginal cost structure of all other firms in the market. The paper investigates the difficulties arising from airport benchmarking as well as the benefits that might be derived from it by drawing lessons from benchmark regulation in other industries and the few cases where it has been applied to airports. In particular, it assesses whether yardstick regulation is a feasible alternative to the existing forms of economic regulation or whether yardsticks are more useful for internal management purposes.
