Denaro linguistico e plusvalore ideologico. Estensione dell’omologia fra economia e semiotica

Our contribution intends to recall the idea of linguistic money as it was formulated by Rossi-Landi in his theory of the homology between linguistic production and material production. We will resume the most important linguistic theories of value that were influenced by economic theories of value, and the critique that Rossi-Landi addressed to them all. We will show how it can be extended to other theorists of the Seventies. Then, we will extend Rossi-Landian homology to the concept of plus-value, according to his semiotics, but by following Marx’s analysis of the value and of the production of plus-value.
