ABSTRACT
The general objective of this piece is to analyze the formulations developed by three interpretative strands of Keynes’ investment theory, specifically with regard to the interrelationships between real and monetary-financial variables. After highlighting the innovative character of Keynes’ formulation on the issue, the author goes through the approaches of neo-Keynesians (neoclassical synthesis), post-Keynesians, and New Keynesians, in an attempt to focus on the central question of the article, that is, to assess the existence or not of possible relationships between the new Keynesians and the two other approaches with regard to the links between finance and investment. In particular, the author aims to assess whether or not the formulations of the new Keynesians represent a convergence between neo and post visions.
