Le comportement des producteurs de biens addictifs légaux : implications d'une demande avec interactions sociales.

This article analyzes the behavior of a producer of a legal addictive good (tobacco, alcohol or gambling) facing a demand with social interactions, especially a deterrence effect of heavy use on initiation. We simulate an epidemic model to estimate at what conditions it could be interesting for him to act responsibly, which means to reduce the escalation rate (from light use to heavy use). We draw conclusions in terms of the debate on corporate social responsibility discourse/practice in a neoclassical perspective.
