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.
