Tarification optimale et formes contractuelles dans un programme d'infrastructures en ppp

Over the past twenty years, the growth in the use of ppps for news infrastructures did not knock down the bases of public economics. This article examines, however, in which measure it is advisable to modify the use of the cost-benefit analysis by the public authorities in the case of ppps, in order to optimize either the programming of the investments or their pricing. Of the coherence between these two optimizations results a principle of optimal pricing for programming as well as the shape of contract which corresponds to him. Although these results are probably useful other fields of public policies, this article is inspired by the declension of these questions in the case of transport infrastructures for which it is a crucial issue today.
