One of the main pillars of efficient airport operations is cost-minimization. Unit costs of operation with respect to the level of passengers served are a possible proxy to measure the cost efficiency of an airport. Due to compound production framework and sophisticated political-economic...

The larger West European countries, in particular France, the UK and FR Germany, have launched plans for setting up wider cable TV networks. It appears, however, that they will not achieve the high penetration levels reached in some of the smaller countries such as the Netherlands, Belgium and...

The author considers the potential benefits and problems of deregulation in the telecommunications sector. He discusses competition (a) in terminal equipment supply and (b) in network provision. Assessing both areas in the light of US experience, he draws up recommendations for liberalized...

This paper analyses the major effects of liberalization in the Nordic countries (Norway, Sweden, Denmark and Finland) and the likely evolution of telecommunications policy in the light of their involvement in the European Economic Area. The structure of the actors, their regulation and envisaged...

Events since 1989 have profoundly altered the political and economic shape of Eastern Europe. The European Community, in particular, faces new challenges and oppurtunities as it is called upon to help in the restructuring of the old command economies, and it also has difficult decisions to make...

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...

The motion of individual Brownian particles is observed using the confocal Tracking Microscope recently introduced by Schätzel (K. Schätzel, W. G. Neumann, J. Müller and B. Materzok, App. Opt. 31 (1992) 770–778). Particles are laterally trapped in a strongly focused laser beam. By...

This paper outlines some first results from a study on the technical efficiency and total factor productivity (TFP) of 17 international airports in Germany. The analysis was undertaken with panel data from 1998 - 2002. According to the Malmquist-DEA the performance at nearly every airport...
