His model was subsequently formalized by John Fei and Gus Ranis, who ended up at Yale. Ranis also made the first formal empirical application, looking at. from phase one to phase two growth, as defined in the Lewis-Ranis-Fei model. This implies that phase three growth could be achieved by the commercialisation. The upcoming discussion will update you about the difference between Lewis model and Ranis-Fei model. According to Rains-Fai point (end of the first phase) .

This would mean that the productivity of laborers with rise in income will not rise. This is extremely desirable for the economy, as the growth of industrial goods is subject to the rate of per capita income, while the growth of agricultural goods is subject only to the rate of population growth, and so a bigger labor supply to the industrial sector would be welcome under the given conditions.
The unemployment level is defined as the labour force minus the number of people currently employed, the unemployment rate is defined as the level of unemployment divided by the labour force. The higher productivity of well-educated workers is one of the factors that explain higher GDPs moedl, therefore, a strong correlation between GDP and education is clearly visible among the countries of the world, as is shown by the ranls left figure.
The difference of the two terms yields the total agricultural surplus of the economy. In other words, the slope of ORX curve represents real wage rate.

It is important to understand that this surplus is produced by the reallocation of labor such that it is absorbed by the industrial sector. It can be surmised then that under normal cases, the output would decline with shift of labor to industrial sector, although the per capita output would remain the same. A four-stage centipede game. This page was last edited on 20 Aprilat This suggests that increase in surplus becomes more important a determinant as compared to re- investment of surplus, an idea that was utilized by Jorgenson in his model that centered around the necessity of surplus generation and surplus persistence.

If the migration to industrial sector continues a situation is eventually reached where the farm workers produce output equal to institutional wages. Technological advancement often reduces frictional unemployment, for example, internet search engines have reduced the cost, structural unemployment — This reflects a mismatch between the skills and other attributes of the labour force and those demanded by employers.
Since the growth process will observes a slow-paced increase in the consumer purchasing power, the dualistic economies follow the path of natural austeritywhich is characterized by more demand and hence importance of capital good industries as compared to consumer good ones.
