This article develops the classical and Marxist theory of growth, establishing their basic links and main features, that is, the bond among their theories of value, distribution, accumulation and growth, centered around the concept of surplus, and the key role of the sphere of production in the determination of those theories.   The exposition tries to show up the unity, continuity and progressiveness theoretical-analytic among the theories of the Physiocrats, Smith, Ricardo and Marx. In all of them it is analyzed the meaning of the saving-investment process and its relation with the growth, specially their stance with regard to the Say's Law.

The standard interpretation of Harrod' s economics dynamics heavily dependent on the so-called "Harrod-Domar" model of economics growth is misleading for an accurate assessment of Harrod' s model. In arder to do that this articles explores the connection between Harrod 's economics dynamics and Keynes' work by showing how sorne key analytical tools and the "vision", in a schumpeterian sense, for the formulation of an economics dynamics in Harrod are based on, or developed from, Keynes's General Theory and his criticism to the "classical economics".   Keynes' influence is observed in the general structure of the model and on the mechanisms under which is analyzed the long-term economic growth. It is intended to show those key elements that make evident that and the degree of their importance in the mathematical structure of the model and in the extent of Harrod's conclusions. With that a...
