Abstract: Public authorities as well as private operators are both taking part of the transport sector's organisation. Moreover, the European commission, acting to set markets' free and the strong constraints on states' budgets are strengthening private operators' place on the transport market.Then, two different pricing strategies have to be considered. One of them focusing on welfare maximisation and the other one targeting financial profitability. Economic theory often consider the results from these two pricing policies as antagonist. Is that true?Thanks to an easy simulation, our study shows, while considering a program of projects to be done with budget constraints, that the price maximising the return on investment is also the optimum price in terms of welfare maximisation. Stronger the constraints are, and more this establishment becomes true.This analysis may have great impacts on transport pricing policies and in terms of transport sector organisation.
