Ricardian, ECLAC-UN (Cepal) and Neo-Schumpeterian schools of Economic Thought assume that there are productivity differentials across economies.

Conclusions highlight the limits of the neoclassical model in explaining the intertemporal trade when productivity differentials across countries are assumed.
