Copyright © Pearson Addison-Wesley. All rights reserved The International-Dependence Revolution n The neocolonial dependence model n The false-paradigm model n The dualistic-development thesis n Evaluation
Copyright © Pearson Addison-Wesley. All rights reserved Neocolonial dependence n Rich, powerful center and poor, powerless periphery n Underdevelopment as dependent capitalism –Development depends on outside influences in periphery –These may be negative, and prevent catching up (Development of underdevelopment) n Comprador Classes
Copyright © Pearson Addison-Wesley. All rights reserved False Paradigm n Intellectual Dominance of the west leads to irrelevant or harmful theories
Copyright © Pearson Addison-Wesley. All rights reserved Dualistic Development n Permanency of dualistic structures in and between countries
Copyright © Pearson Addison-Wesley. All rights reserved Evaluation n Coexistence of seemingly dualistic regions (Africa?, Latin America?) with regions leaving poverty (historically: Russia, presently: China, India)
Copyright © Pearson Addison-Wesley. All rights reserved The Neoclassical Counterrevolution n Challenging the state-driven model n Traditional neoclassical growth theory n Conclusions and implications
Copyright © Pearson Addison-Wesley. All rights reserved Challenging the state driven model n Free market approach –Free markets allocate resources best to investment (equipment, human capital, R&D) –Imperfections are of little consequence n Public choice approach –market failures (monopolies, externalities) have to be compared to state failures (interest groups, bureaucratic self-interest, etc.) n Market-friendly approach –In LDC´s market failures are particularly heavy. –The states role is to make markets work
Copyright © Pearson Addison-Wesley. All rights reserved The (neo)institutionalist view n Wealth-creation is driven by deepening the division of labour
Copyright © Pearson Addison-Wesley. All rights reserved Division of Labor n Increased Specialization –= increasing use of economies of scale –= exploiting comparative advantages n Implication: increased exchange
Copyright © Pearson Addison-Wesley. All rights reserved The division of property rights n E.g. –Rent (Property/ownership) –Joint Stock Co. (Property/Management) –Labor contract (Property/Ownership) contrast: slavery –Loan (temporary separation) n Idea: assignment of rights to the “best” = “highest utility” user
Copyright © Pearson Addison-Wesley. All rights reserved Evaluation n A general theory of economic wealth creation n No specific role for markets/state as a mechanism in principle at this level of generality n A guiding structure of thought, not a recipe book
Copyright © Pearson Addison-Wesley. All rights reserved Traditional growth theory n Solow Growth model
