International Transport Forum Discussion Papers

ITF Discussion Papers make economic research, commissioned or carried out in-house at the International Transport Forum, available to researchers and practitioners. They describe preliminary results or research in progress by the author(s) and are published to stimulate discussion on a broad range of issues on which the ITF works.

The Efficiency Impact of Open Access Competition in Rail Markets

The Case of Domestic Passenger Services in Europe

On-track competition in passenger services has traditionally been limited in European railways, with private operators offering marginal services in selected corridors in the UK, Sweden and Germany only. In recent years, a larger scale and more stable wave of open access market entry has occurred in Austria, the Czech Republic and Italy, where open access operators have gained market shares of 20-30% in long-distance corridors.

Economic theory suggests that competition can result in productive efficiencies, although theories of competition are potentially outweighed by market characteristics which make monopoly a more efficient market structure when applied to the rail sector. The contestability of rail markets is further hampered by the presence of several barriers to entry as well as expansion.

The literature on the efficiency effect of rail policy changes is vast, but the focus to date has been on industry structure and competitive tendering, with non-conclusive results highlighting the importance of tailoring rail policies to the specific characteristics of each network. Studies have not yet attempted to measure the industry efficiency impact of passenger open access operations, neither specifically nor systematically – which is the goal of this paper.

Using a difference-in-difference estimator, we find that on-track competition has not, to date, led to major efficiency improvements across the rail systems affected – despite claims that new entrants have lower unit costs compared to incumbents. In the early days of market opening when guarantees of non-discriminatory access have not yet been fully established, on-track competition may be resulting in higher costs than in countries with monopoly passenger services.

These results are based on a short timeframe and will need to be tested over a longer period, recognising that competition is a process with no instantaneous effects. An early assessment of market opening policies is crucial to inform future regulatory decisions, at a time of budgetary constraints, forthcoming European reforms under the Fourth Railway Package and growing interest in market entry by new operators.
