B The Closed Economy :<br />
Assumptions :<br />
Lewis’ model is based on the following assumptions;<br />
1. There exist unlimited supplies of labour in the economy.<br />
2. The economy is dualistic in nature.<br />
3. The cost of imparting training and skill to the unskilled labour is assumed to<br />
remain constant through time.<br />
4. The production in expanding capitalist sector takes place according to the<br />
principle of profit maximization.<br />
5. The capitalist sector operates by employing the reproducible capital and wage<br />
labour.<br />
6. The subsistence sector does not make use of reproducible capital.<br />
7. The per capita output in the subsistence sector is considerable smaller than<br />
that in the capitalist.<br />
8. The relationship between the capitalist and the subsistence sector lies in the<br />
fact that as former expands; it draws labour from the latter.<br />
9. The wages which the expanding capitalist sector is not absolutely larger in<br />
relation to population growth.<br />
B Two Sector Economy :<br />
Lewis divides the economy of an underdeveloped country into two sectors the<br />
capitalist sector and the subsistence sector.<br />
i) Capitalist Sector :<br />
The capitalist sector is defined as, “that part of the economy which used<br />
reproducible capital and pays capitalists for the use of thereof.” The use of capital is<br />
controlled by capitalists, who hire the services of labour.The capitalists sector does<br />
not include only manufacturing but also plantations and mines where labour is hired for<br />
profit. The capitalist sector may either by private or public.<br />
ii) Subsistence Sector :<br />
The subsistence sector is that part of the economy which is not using reproducible<br />
capital. It can also be designated as the indigenous traditional sector or the “selfemployment<br />
sector”. Output per head is much lower in this sector than in the capitalist<br />
sector, there is existence of disguised unemployment in the agricultural sector whose<br />
marginal productivity is zero in this sector.<br />
