This article explores the causes and consequences of urbanization in the Middle East and North Africa region, with a focus on the economic factors driving urban population growth. It also discusses the Lewis and Todaro models, as well as policy implications and challenges associated with rapid urbanization.
E N D
Urbanization and Development • Economic development causes urbanization • There is a positive correlation with economic development and urban population growth
Many ME & NA countries experience rapid urban population growth because of Natural increase: birth rate > death rate Rural-urban migration: movement of rural workers to urban areas Urbanization
Contribution of R-U Migration • On average, about 50% of urban population growth is due to R-U migration • Rapid R-U migration has resulted in the construction of slumps and shanty towns that house a large percentage of urban population (e.g., Cairo)
The Lewis Development Model • Rural agricultural sector • Low or even zero Marginal Product of Labor so that labor is a redundant factor and wage rate is at the subsistence level • Urban industrial sector • Rising demand for unskilled labor to be trained for industrial growth results in greater employment and more profits and higher wages • Rural-Urban migration • To find jobs and earn higher wages
Demand for Labor Wage R: Rural U: Urban W: Wage E: Employment D: Labor Demand S: Labor Supply Profit WU SR Investment inurban areas increases the demand and employment for rural labor. WR Wage DU2 DU1 E2 E1 Employment
Criticisms of Lewis Model • Industrial technology is generally capital intensive/labor-saving. Hence, the demand for unskilled rural labor would not increase employment • Industrialization must be supported by agricultural development to supply an ever-increasing supply of food items and raw materials
Demand for Labor Wage No increase in employment when technology is labor saving Profit SR WU WR Wage DU1 DU2 Employment E1 = E2
Todaro’s R-U Migration Model • Factors affecting migration decision • Expected urban income • Probability of finding an urban job • Cost of living in urban areas • Decision criterion: • Migration will take place if the “expected” benefits exceed the costs (in present value)
Todaro’s R-U Migration Model Benefits from migration: • Difference between “expected” urban income and rural income (R-U wage differential) • Psychic benefits Costs of migration: • Transportation cost • Opportunity cost of being unemployed • Difference in living expenses • Psychic costs
Todaro’s R-U Migration Model Non-economic factors inducing migration: • Distance • City lights: movie theaters, restaurants, etc. • Relative living in urban areas helping reduce living expenses • Information flow about job openings in the “informal” sector
Policies Inducing R-U Migration • Neglect of agriculture • Urban bias development strategies • Job creation in urban areas • Educational opportunities: R-U brain drain • Urban wage subsidies
Policies Reducing R-U Migration • Eradicate poverty and reduce population growth • Promote rural and agricultural development • Expand small-scale, labor-intensive industries • Eliminate factor-price distortions and adopt “appropriate” production technologies • Modify direct link between education and employment
Rapid Urbanization Problems • Congestion and pollution • Unemployment and underemployment • Overcrowding and crime • Insufficient accommodation such as housing and transportation • Possibility of political unrest
