ABSTRACT
This chapter proposes a critical panorama of Kantian-inspired economics. It examines the various ways taken to formalise the Kantian hypothesis in economics from the principle of generalisation. They have enabled the construction of an "ordinary" Kantianism. The chapter focuses on the first models which achieved this integration. It establishes the difference between the Kantian principle adapted to economics and the principle of reciprocity. The chapter brings to light a principle of unconditionality of action. It also focuses on the notion of commitment, which is interpreted within the Kantian framework, but takes on various forms, for example with the distinction between Kantianism and "superKantianism". The Kantian solution as proposed by J. Laffont, offers a prospect of results, which is both unlikely and deviates singularly from Kantian philosophy. Finally, the chapter concludes on the lessons, which should be drawn from the Kantian hypothesis in economics.
