There
are numerous growth models in literature. However, there is no consensus as to
which strategy will achieve the best success. The achievement of sustained
growth requires minimum levels of skills and literacy on the part of the
population, a shift from personal or family organization to large scale unit
(Nnanna, 2004). Some of these existing growth models are Two-Gap Model, Marxian
Theory, Schumpeterian Theory, Harrod-Domar Theory of Growth, Neo-Classical
Model of Growth, and
Endogenous Growth Theory. The growth models relevant to
this are Neo-Classical Model of Growth, and Endogenous Growth Theory, since
these growth models explain the situation in developing economies such as
Nigeria, Ghana, etc.
