ETC 2004 Strasbourg An application proposal of yardstick competition to the regional markets of the French railway system Julien LEVEQUE jleveque@let.ish-lyon.cnrs.fr Laboratoire d’Économie des Transports (CNRS) 5 October 2004
ETC 2004 Strasbourg Framework The French monopoly problem The French monopoly problem � The French railway services (freight, inter-city, regional): 1938 1983 1994 2004 1 1 1 number of operators 1 SNCF SNCF SNCF operators SNCF � The regional rail transport services (TER): � suburban trains � interurban trains � rural trains 2
ETC 2004 Strasbourg Framework Current organization organization Current Average regional network in 2002: � 450 M P.K 64 P/Tr � 7.1 M Tr.K � 1157 km of lines � 70.7 km/h � traffic revenues = 40 % costs � operating income: 100 M € � operating result: 3.7 M € 3
ETC 2004 Strasbourg Framework Which incentives? Which incentives? delegate TER services 20 regional 1 operator regulators captures � Contracts (5-10 years) define PSO and subsidies: � quality incentives: bonus/malus � traffic incentives: SNCF bears the commercial risk � cost incentives: “RPI” + 0!!!!!!!!! � no call for tender lack of competitive pressure on costs 4
ETC 2004 Strasbourg Economic principles The yardstick competition mechanism The yardstick competition mechanism � Shleifer : Estimating what should be the best prices and subsidies, by comparing the performances of several similar, regulated firms: ∑ costs of firm j ≠ j i = revenues of firm i − N 1 costs of the compared firms have to be homogenous! 5
ETC 2004 Strasbourg Economic principles The proposed scheme: The proposed scheme: � Comparing the performances of the 20 regional SNCF departments � Implementation by a common agency of the regional regulators � Which incentives ? - financial gains / penalties - reputation effect 6
ETC 2004 Strasbourg Economic principles Benefits of the use of comparisons Benefits of the use of comparisons � reduction of the uncertainty due to: - prices increase - changes in labour legislation - national strikes � reduction of the informational rent due to: - spatial organization - labour organization 7
ETC 2004 Strasbourg Measure of efficiency Correcting external heterogeneity Correcting external heterogeneity � endogenous heterogeneity: due to political decisions in defining PSO Nash : customer = government, output = level of service: Tr.K ( ≠ number of P.K) � exogenous heterogeneity: due to the environment (infrastructure, society) introduction of environmental variables in the model 8
ETC 2004 Strasbourg Measure of efficiency The cost frontier model The cost frontier model � data issued from the regional accounts of the SNCF (1997 & 1998) � stochastic cost frontier : ∑ = β + β + β + β + + lnC lnTr.K lnL.L lnw v u it 0 1 it 2 it k k, it it it > k 2 � control of the external heterogeneity : ∑ = δ + δ + ε u Z it 0 k k, it it ≥ k 1 9

ETC 2004 Strasbourg Conclusion Towards a more incentive regulation scheme Towards a more incentive regulation scheme � Yardstick competition could be implemented: - while maintaining the legal monopoly of the SNCF - external heterogeneity can be controlled - internal heterogeneity (inefficiency) is quite important � Franchising should be introduced in addition 13
ETC 2004 Strasbourg Conclusion Thank you Thank you for your attention for your attention 14
