Fei ranis theory

This is a one-sided theory because Lewis does not consider the possibility of progress in the agricultural sector. Short-run equilibrium, rural In the short-run, what happens in the countryside if: In the third stage of FR model the take-off situation comes to an end and there begins the era of self- sustained growth where the farm workers produce more than the institutional wage they get.

The locus of such Fei ranis theory of indifference is given by the I1I1 curve. I0 and I1 between the two commodities of food and leisure of the agriculturists. In fact, it says that the rate of growth of the industrial sector depends on the amount of total agricultural surplus and on the amount of profits that are earned in the industrial sector.

Dual-sector model

The amount of TAS is a function of the number of workers shifted to the industrial sector in each phase of the development process. There is perfect substitutability between food and leisure, and the marginal rate of substitution is constant for all real income levels.

This would mean that the productivity of laborers with rise in income will not rise. Thus FR model believes in 'Balanced Growth' in the take-off stage. This inhibits growth since technical progress necessary for growth requires skilled labor.

This surplus or profit can increase if the MPL curve changes. The growth of surplus generated within the agricultural sector, and the growth of industrial capital stock dependent on the growth of industrial profits; 2.

Hence, labor employment continues as ON and wages as OW.

Fei–Ranis model of economic growth

Labour is abundant and disguised unemployment is the result. First published in The Manchester School in May[2] the article and the subsequent model were instrumental in laying the foundation for the field of developmental economics.

The first stage of FR model is very similar to Lewis. Lewis assumes that the capitalist surplus is reinvested in productive capital. As the productivity of agriculture increases, it becomes possible for just 35 per cent of population to maintain a satisfactory food supply for the rest of the population.

How then can things be equilibrated. There are reasons to believe that the relationship between money and physical capital could be complementary to one another at some stage of economic development, to the extent that credit policies could play an important part in easing bottlenecks on the growth of agriculture and industry.

Of course, it also required high levels of inventory of goods in process, and controlling quality could also be problematic. Agricultural surplus plays a major role as a wage fund. Generation of agricultural surplus[ edit ] Agricultural surplus in the dual economy of Fei and Ranis To understand the formation of agricultural surplus,we must refer to graph B of the agricultural sector.

Unsourced material may be challenged and removed. In the second phase, agricultural workers add to the agricultural output but produce less than the institutional wage they get. What then happens to relative wages. However, as long as surplus exists, growth rate can still be increased without a fall in the rate of industrialization.

The agricultural surplus JF created is needed for consumption by the same workers who left for the industrial sector. These capital goods are needed for the creation of employment opportunities. The line WW' running parallel to the X-axis is considered to be infinitely elastics since supply of labor is assumed to be unlimited at the subsistence-wage level.

Growth without development[ edit ] Graph showing growth without development In the Fei-Ranis model, it is possible that as technological progress takes place and there is a shift to labor-saving production techniques, growth of the economy takes place with increase in profits but no economic development takes place.

Following Lewis the FR model argues that AD units of labor are the surplus amount of labor in agricultural sector which is prey to disguised unemployment. Lewis divided the economy of an underdeveloped country into 2 sectors: Fei and Ranis hypothesize that it is equal to the real wage and this hypothesis is known as the constant institutional wage hypothesis.

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.

Eventually, the wage rates of the agricultural and manufacturing sectors will equalize as workers leave the agriculture sector for the manufacturing sector, increasing marginal productivity and wages in agriculture whilst driving down productivity and wages in manufacturing.

Fei–Ranis model of economic growth

The Engel curve, the share of income spent on food as income per capita rises. This can be seen as deployment of hidden rural savings for the expansion of the industrial sector. But it is not true. While the labor force values are read from the left of 0, the output values are read vertically downwards from O.

In fact, it says that the rate of growth of the industrial sector depends on the amount of total agricultural surplus and on the amount of profits that are earned in the industrial sector. OS represents the subsistence level of food consumption, or the minimum level of food consumed by agricultural labor that is necessary for their survival.

John Fei and Gustav Ranis have presented in an article entitled, “A Theory of Economic Development”, the process of rural-urban migration in underdeveloped countries.

The model is related to an underdeveloped economy having surplus labour but scarcity of capital. 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. According to Chen (), Lewis-Ranis-Fei model should be considered a classical model because of the usage of industrial wage.

However, Jorgenson claims that once the commercialization point is reached, instead of the classical approach, the neo-classical theory of growth for an advanced economy is to be observed (Jorgenson, ).
