iii) Relationship between the two sectors : When the capitalist sector expands, it draws labour from the subsistence sector. As a result, output per head of labours that move from the subsistence sector to the capitalist sector increases. In this situation new industries can be created, or old industries expanded at the existence wage rate. That results more unskilled labour move from subsistence sector to capitalist sector.The migration will be continued till the wages offered by subsistence sector. Labour will not leave the family from to seek employment elsewhere if the wage that is offered to them is less than their marginal productivity. In fact wages offered by the capitalist sector will have to be somewhat higher than subsistence wages in order to compensate labour for the cost of transfer and to induce labour to leave the traditional way of life of the subsistence sector.According to Lewis, there is usually a gap of 30 per cent or more between capitalist wages and subsistence earnings.

B The Process of Economic Expansion : Lewis emphasizes on the reinvestment of capitalists’ surplus for creation new capital. Therefore the amount of fixed capital increases and the schedule of the marginal productivity of labour rises to the level of N 2 Q 2 . The total product rises to ON 2 P 2 M 2 . As a result, the share of wages increases to OWP 2 M 2 and capitalists’ surplus or profit also rises to WN 2 P 2 . An increased part is again reinvested leading to a further rise in total product. At each stage, capitalists’ surplus and the level of employment in the capitalist sector increases from OM 1 to OM 2 , OM 3 etc. as labour withdraws from the subsistence sector into Capitalist Sector, there is larger investment of profits and the process continues as long as there is surplus labour exhausted from the subsistance sector. B The Role of Savings: The role of savings in the process of growth is crucial and important. In this model capitalists surplus do not reinvest, neither will the total product expand nor will opportunities for employment increase. Therefore, unless savings increase, economic growth cannot take place. Lewis argues that because of extreme inequalities of income and wealth in underdeveloped countries, the capacity to save is limited to about 10 per cent of the richest people. If the saving of richest people increases the process of growth expands, the poor and middle class people does not save, because of their capacity to save is low. The reason of low saving in underdeveloped country because their capitalist sector is small. Also there exist unequal distribution of income and wealth. If these countries had a larger capitalist sector, profits would be a greater part of their national income, and savings and investment would also be greater. B Role of Bank Credit: Lewis admits the possibility that capital creation is also possible as a result of a net increase in the supply of money especially bank credit. Bank credit is important for development of underdeveloped countries which have idle resources and surplus labour supply. In underdeveloped countries, the effect of bank credit on capital formation is similar to that of reinvestment in profits. Bank credit helps in the expansion of employment, output, effective demand and purchasing power of the community. B End of Growth Process: Lewis model shows that if unlimited labour is available at constant real wage, the capitalist surplus will rise continuously and annual investment will be a rising proportion of national income. But this process of economic growth cannot go for ever. It comes to an end when there is no surplus labour.According to Lewis, the growth process comes to an end due to following reasons. i. The capitalist sector expands so rapidly that it reduces absolutely the population 123456789012345678901234567890121234567 123456789012345678901234567890121234567 21 123456789012345678901234567890121234567 123456789012345678901234567890121234567 123456789012345678901234567890121234567 123456789012345678901234567890121234567 123456789012345678901234567890121234567 123456789012345678901234567890121234567
