Le contrat de régulation optimale d'un monopole avec deux paramètres d'information privée et d'antisélection (productivité et niveau d'émissions polluantes) est caractérisé. Dans ce contexte de screening bidimensionnel, un aspect d'économie politique est introduit en considérant...

We propose a model representing a newspaper producer supplying a product which can be acquired by the readers either every day per one unit at a time, or by subscription. The population of potential buyers is differentiated according to the frequency at which they want to read the newspaper....
