摘要：We analyze potential gains from hypothetical mergers in local public transport
using the non-parametric Data Envelopment Analysis with bias corrections by
means of bootstrapping. Our sample consists of 41 public transport companies
from Germany's most densely populated region, North Rhine-Westphalia. We merge
them into geographically meaningful, larger units that operate partially on a
joint tram network. Merger gains are then decomposed into individual technical
efficiency, synergy and size effects following the methodology of Bogetoft and
Wang [Bogetoft, P., Wang, D., 2005. Estimating the Potential Gains from Mergers.
Journal of Productivity Analysis, 23(2), 145-171]. Our empirical findings
suggest that substantial gains up to 16 percent of factor inputs are present,
mainly resulting from synergy effects.
