When defining how to implement tendering procedures
for the regional bus transportation industry, one of the main problems
local authorities have to face is setting the area size to be assigned
as franchised monopoly.
This paper's aim is to analyze the topic by combining some empirical
results and evidence from recent experience [developments] in the
Italian regional bus industry. The empirical results show that the
bus transportation sector is characterized by the presence of economies
of density and scale. These results imply that the best strategy for
introducing competition in the bus industry is a competitive tendering
approach for an area of given dimension and not necessarily a route-by-route
tendering. However, it seems that the criterion applied by local authorities
in Italy is much more related to political issues - such as jurisdictional
boundaries of a municipal or provincial area - than a desire to promote
the exploitation of economies of scale and density.
