Abstract

We investigate some technological aspects of railroading relevant to the debate on open access by estimating a multiproduct cost function with both operational outputs and infrastructure maintenance outputs. We find strong cost complementarities among operational outputs, but not between operations and infrastructure. The latter result implies that at the levels of output that characterize freight rail operations in the U.S. there may be no inherent technological advantages from vertical integration. The former suggests though (for reasons that we develop below) that competitive access alone will not necessarily lead to competitive outcomes in rail freight markets.
