Structural Change and Macrodynamic Capabilities

In this paper we intend to study some mechanisms that block a rapid diffusion of technological progress from advanced to underdeveloped countries. In order to accomplish this task we focus on two approaches that challenge the view that technological gaps between rich and poor nations are diminishing. The first is the structural economic dynamic approach and the second is the evolutionary view. Both of them reveal that the elimination of the technological gaps between rich and poor nations is more complex than what is been reported by the mainstream theory of economic growth.
