The Lewis model fits better than the Harris-Todaro Model in the explanation of the pattern of development experienced by Venezuela.
Reason
The Lewis model predicts that in a developing economy, workers move from the agricultural sector to the manufacturing sector, leading to an increase in the average income and urbanization, and reduction in inequality and poverty (Misra & Puri, 2010). On the other hand, the Harris-Todaro Model predicts that workers move from the rural to the urban areas, expected income in the urban areas reduces, and the wages in the agricultural sector increase. The equilibrium is reached where the expected wages in the rural and urban areas are equal. Eventually, unemployment in the urban areas increases, and employment in the urban informal sector increases (Lall & Selod, 2006).
Evidence
Economic development in Venezuela between 1989 and 2010 followed the predictions of the Lewis model. As expressed in table 2 in the appendix, income per capita increased from US$2,382 in 1989 to US$13,559 in 2010. The Gini index reduced from 43.8 percent to 39 percent over the same period. Within the same period, the number of people living in the urban areas increased from 84 percent to 93 percent (World Bank, 2014).
Acknowledgement
The Lewis model is based on the assumption that excess, unproductive labor in the agricultural sector moves in the manufacturing sector where there are higher wages than in the agricultural sector (Misra & Puri, 2010).
Response
The assumption of the Lewis model may not always hold. When this happens, empirical results derived in studies may be opposite of expectations (Misra & Puri, 2010). A good example is the increase in poverty levels in Venezuela from 31.3 to 32.5 between 1989 and 2010, as indicated in table 2 in the appendix.
