The North–South model, developed largely by Columbia University economics professor Ronald Findlay, is a model in developmental economics that explains the growth of a less developed "South" or "periphery" economy that interacts through trade with a more developed "North" or "core" economy. The North–South model is used by dependencia theorists as a theoretical economic justification for dependency theory.〔Abdenur, Adriana ("Tilting the North South Axis" ), ''Princeton University'', 2002, accessed June 24, 2011.〕 ==Assumptions== The model makes a few critical assumptions about the North and the South, as well as the relationship between the two.〔Molana, H. ("North South Growth and the Terms of Trade" ), ''The Economic Journal'', 1989, accessed June 24, 2011.〕 * The Northern economy is operating under Solow-Swan assumptions while the Southern economy is operating under Lewis growth assumptions. However, for the purposes of simplicity of this model, the output of the traditional sector of the Lewis model is ignored, and we equate output in the modern sector of the South to total output of the South. * The more developed North produces manufactured goods while the less developed South produces primary goods. These are the only two goods. * Both economies undergo complete specialization * There are no barriers to trade, and only two trading partners * Income elasticity of demand equals unity in both countries, so economic growth results in a proportionate growth in demand. * The South depends on the imported goods from the North in order to produce its own goods. This is because the heavy machinery required for production of primary products comes only from the North. The relationship is nonreciprocal, however; the North does not depend on the South, since it can use its own heavy machinery to produce manufactured goods. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「North–South model」の詳細全文を読む スポンサード リンク
