The controversy over intellectual property in nineteenth-century France: a comparative analysis between Proudhon and Walras

The debate over intellectual property in nineteenth-century France was structured as follows: liberal economists advocated a system of perpetual intellectual property rights, while socialist thinkers called for their total abolition. Between these two extremes, other economists supported a temporary form of intellectual property: in particular, Pierre-Joseph Proudhon and Léon Walras both converged towards this third solution. This article shows that they in fact provide two different analyses of intellectual property rights, which partly overlap with positions in current debates in innovation studies.
