This paper considers the threat of stricter regulation as a policy instrument to enhance innovation into cleaner technology. It is argued that in some contexts the government would find it optimal to regulate with positive probability but not with certainty. In those contexts the optimal policy is indeed made of regulatory threats; furthermore, we show that it is time-consistent, credible, involving little information, and immune to ex post renegotiation.
Ce document considère la menace d'une réglementation environnementale plus stricte en tant qu'instrument de politique économique visant à stimuler l'innovation. Il est démontré que, dans certains cas, le gouvernement préférerait réglementer avec une probabilité positive pas avec certitude. Dans ces situations, la politique optimale est en effet constituée de menaces de réglementation ; il est de plus démontré qu'elle est cohérente dans le temps, crédible, peu exigeante en information et robuste à la renégociation.
