The classical eco- mics books have developed different theories and considered several f- tors that could explain those processes. Unfortunately, a single answer has not been obtained and nowadays economists try also to achieve a response to the mechanism of economic growth. Economic growth has been considered as one of the most relevant e- nomic policy. As it is well known, the validity of an economic policy is measured in terms of economic growth rate. It is supposed that those countries that obtain a higher economic growth rate are designing more efficient economic policies than those that show lower rates. The main corollary to this hypothesis is that the developing countries must follow and copy the economic policies designed by the developed countries.
