What are the strength and weakness of Lewis model?

The Lewis model, also known as the Lewis dual-sector model, highlights the transition from a traditional agricultural economy to a modern industrial one, emphasizing the role of surplus labor in rural areas. Its strength lies in its clear framework for understanding economic development and labor dynamics, particularly in developing countries. However, a significant weakness is its oversimplification of complex economic realities, ignoring factors like technological change, institutional differences, and the impact of globalization on labor markets. Additionally, it may not adequately address social and cultural factors influencing labor migration and employment.
