Sustainable Development in a Post Keynesian Perspective: Return to Basics of Ecodevelopment (In French)

While sustainable development is a unanimously accepted watchword today, we wish to show that the post Keynesian school, even if it did not emphasize on environmental issues and, generally speaking, on sustainable development as such, has tools that make it relevant on this topic. Indeed, post Keynesian sustainable development can be close to Sachs’ ecodevelopment, which is inspired by Kalecki. Thus, post Keynesianism and ecodevelopment share the same position related to economic growth. They meet, via the concept of radical uncertainty, on the importance of the precautionary principle. If the implications of the principle of effective demand seem to oppose them, these divergences can be easily overcome.
