n the dual-economy model (Lewis), the turning point:(1 Point)Requires a change in the division of labourRefer to the need of increasing the ICORRequires more savings in the agricultural sectorRefer to the situation where there is no more surplus in the agriculture sector

In the dual-economy model proposed by Arthur Lewis, the turning point refers to the situation where there is no more surplus labor in the agricultural sector.

Here's a step-by-step explanation:

1. The dual-economy model is a concept in developmental economics that explains the existence of two separate economic sectors within one country, divided by different levels of development, technology, and different patterns of demand.

2. According to this model, one sector is traditional (agricultural) and characterized by low wages and low productivity, while the other is modern (industrial) and characterized by high wages and high productivity.

3. The model assumes that there is surplus labor (i.e., unemployment or underemployment) in the traditional agricultural sector, which can be transferred to the modern industrial sector.

4. The "turning point" in this model is the point at which all surplus labor in the traditional sector has been fully absorbed into the modern sector. This means there is no more surplus labor left in the agricultural sector to be transferred to the industrial sector.

5. This turning point is significant because it implies that further growth in the industrial sector can no longer be achieved by transferring labor from the agricultural sector, but must come from increases in productivity or capital.
