Rail infrastructure charging in Hellenic railways

In this paper we consider marginal cost estimation in Greek railways over the period 2000-2004. Marginal cost estimation has been recently an active area of research when disaggregated data by line of operation are available but factor price data are not available. We propose panel data techniques to deal with the problem of statistical efficiency of parameters estimators. Our estimates show that marginal cost in Greek railways is comparable to the estimates in other European countries.
