This study concerns a comparison and contrast of two development approaches to determine their applicability in dealing with the global problem of unequal development. Chapter I introduces the purpose and the significance of the study, and the selection of one representative model for each approach. They are W. W. Rostow's model and Samir Amin's model. Chapter II elucidates Rostow's model. Chapter III explains Amin's model. Chapter IV presents a comparison and contrast of the two models both methodologically and conceptually. Chapter V contains the conclusion that Rostow' s model cannot be a universal development model due to its methodological shortcomings, whereas Amin's model should be accepted for its analysis in explaining the reasons' for today's unequal development on a world scale.
