Fei ranis theory

History[ edit ] Initially the dual-sector model as given by W. First published in The Manchester Fei ranis theory in May[2] the article and the subsequent model were instrumental in laying the foundation for the field of developmental economics. The article itself has been characterized by some as the most influential contribution to the establishment of the discipline.

These workers are attracted to the growing manufacturing sector where higher wages are offered. It also assumes that the wages in the manufacturing sector are more or less fixed. Entrepreneurs in the manufacturing sector make profit because they charge a price above the fixed wage rate.

The model assumes that these profits will be reinvested in the business in the form of fixed capital.

An advanced manufacturing sector means an economy has moved from a traditional to an industrialized one. Lewis divided the economy of an underdeveloped country into 2 sectors: The capitalist sector[ edit ] Lewis defined this sector as "that part of the economy which uses reproducible capital and pays capitalists thereof".

The use of capital is controlled by the capitalists, who hire the services of labour. It includes manufacturing, plantations, mines etc. The capitalist sector may be private or public. The subsistence sector[ edit ] This sector was defined by him as "that part of the economy which is not using reproducible capital".

It can also be adjusted as the indigenous traditional sector or the "self employed sector". The per head output is comparatively lower in this sector and this is because it is not fructified with capital.

The "Dual Sector Model" is a theory of development in which surplus labor from traditional agricultural sector is transferred to the modern industrial sector whose growth over time absorbs the surplus labour, promotes industrialization and stimulates sustained development.

In the model, the subsistence agricultural sector is typically characterized by low wages, an abundance of labour, and low productivity through a labour-intensive production process. In contrast, the capitalist manufacturing sector is defined by higher wage rates as compared to the subsistence sector, higher marginal productivity, and a demand for more workers.

Relationship between the two sectors[ edit ] The primary relationship between the two sectors is that when the capitalist sector expands, it extracts or draws labour from the subsistence sector.

This causes the output per head of labourers who move from the subsistence sector to the capitalist sector to increase. Since Lewis in his model considers overpopulated labour surplus economies he assumes that the supply of unskilled labour to the capitalist sector is unlimited.

This gives rise to the possibility of creating new industries and expanding existing ones at the existing wage rate. A large portion of the unlimited supply of labor consists of those who are in disguised unemployment in agriculture and in other over-manned occupations such as domestic services casual jobs, petty retail trading.

Lewis also accounts for two other factors that cause an increase in the supply of unskilled labour, they are women in the household and population growth. The agricultural sector has a limited amount of land to cultivate, the marginal product of an additional farmer is assumed to be zero as the law of diminishing marginal returns has run its course due to the fixed input, land.

As a result, the agricultural sector has a quantity of farm workers that are not contributing to agricultural output since their marginal productivities are zero.

This group of farmers that is not producing any output is termed surplus labour since this cohort could be moved to another sector with no effect on agricultural output. The term surplus labour here is not being used in a Marxist context and only refers to the unproductive workers in the agricultural sector.

Therefore, due to the wage differential between the capitalist and subsistence sector, workers will tend to transition from the agricultural to the manufacturing sector over time to reap the reward of higher wages.

However even though the marginal product of labor is zero, it still shares a part in the total product and receives approximately the average product.fei-ranis theory Introduction Lewis wanted to model development in an economy with a large agricultural sector and a small "modern" sector (e.g., manufacturing).

Fei-Ranis (FR) Model of Dual Economy: The two economists John Fei and Gustav Ranis presented their dual economy model.

There was a flaw in Lewis model that it did not pay enough attention to the importance of agri. sector in promoting industrial growth.

The Fei–Ranis model of economic growth is a dualism model in developmental economics or welfare economics that has been developed by John C. H. Fei and Gustav Ranis and can be understood as an extension of the Lewis model. It is also known as the Surplus Labor model. Fei-Ranis (FR) Model of Dual Economy The Fei–Ranis model of economic growth is a dualism model in developmental economics or welfare economics that has been developed by John Fei and Gustav Ranis and can be understood as an extension of the Lewis model.

The "Dual Sector Model" is a theory of development in which surplus labor from traditional agricultural sector is transferred to the modern industrial sector whose growth over time absorbs the surplus labour, promotes industrialization and stimulates sustained development.
