His contributions

Lewis's Nobel prize-winning work consists of 2 models that describe and explain the problems facing developing nations.


Lewis's two-tier model (Dual Sector model)

This model at its simplest describes an economy with 2 sectors - traditional (with low wages and a nearly infinite supply of labour) and modern (where the bulk of the capital resides). The traditional sector's labour migrates to the modern capitalist sector, attracted by the initially higher wages. Competition forces the wages of workers in the modern sector down to the levels of those in the agricultural sector. This leads to high profits in the modern sector, which finances its further expansion. ... In classical economics and all micro-economics labour is a measure of the work done by human beings and is one of three factors of production, the others being land and capital. ... In politics, a capital (also called capital city or political capital — although the latter phrase has an alternative meaning based on an alternative meaning of capital) is the principal city or town associated with its government. ... Competition is the act of striving against another force for the purpose of achieving dominance or attaining a reward or goal, or out of a biological imperative such as survival. ...


This model thus provides an explanation as to why so often in developing nations, wages remain low and capital rents high, even as development continues apace. A developing country is a country with low average income compared to the world average. ...


Lewis's terms of trade model

Lewis then modelled the way the terms of trade between developed and developing nations are determined. He showed that in trade between 2 groups of countries (rich and poor) who produce 2 products each (food in both, coffee in the poor countries and steel in the rich) and trade the products that are not produced in common, the terms of trade are determined by the relative labour productivities in the agricultural sector. Specifically, the low productivity of labour in the poor countries' agricultural sector compared to the rich countries' agricultural sector will determine the terms of trade between them. Coffee in beverage form. ... The old steel cable of a colliery winding tower Steel is a metal alloy whose major component is iron, with carbon being the primary alloying material. ...
