Abstract: | Abstract By the turn of the twentieth century, Lausanne and Cambridge were the centres of diffusion of two rival versions of marginalism. This paper focuses on the position of Maffeo Pantaleoni, a leading figure of the late nineteenth century ‘renaissance’ of Italian political economy, with respect to the eminent representatives of the two schools: Pareto and Marshall. Pantaleoni's position is examined with reference to the two main bones of contention between Pareto and Marshall, namely general as opposed to partial equilibrium, and pure as opposed to mixed economics. |
