All rights reserved Trends and Projections Urbanization: Greater urbanization is associated with higher per capita income – India and Botswana are “normal” % Population living in cities > 1 million Varies Among High Income Countries – Partly Geography – History?

Copyright © 2009 Pearson Addison-Wesley. All rights reserved The Role of Cities Agglomeration economies – Lower transport costs for intermediate and finished goods – Large pool of workers to draw from – Large pool of firms to work for – Increased specialization: “The degree of (firm, worker) specialization is limited by the extent of the market.” Adam Smith

Copyright © 2009 Pearson Addison-Wesley. All rights reserved The Role of Cities (continued) “Spillovers” (Externalities) – Learn from firms doing similar work Joint ventures “Steal” workers Manage work flow by contracting out and/or subcontracting

Copyright © 2009 Pearson Addison-Wesley. All rights reserved The Role of Cities (continued) Result: Clusters of firms in same industry in same geographic area – Silicon Valley – Show firms in Sinos Valley, Brazil and Guadalajara, Mexico – Artisans of same trade band together

Copyright © 2009 Pearson Addison-Wesley. All rights reserved Dualism in Cities Formal Sector – Government, large businesses – Capital intensive – High(er) wages and often benefits Informal Sector – Labor intensive – Unorganized, unregulated, mostly legal – Often, Self- or Family-employed

Copyright © 2009 Pearson Addison-Wesley. All rights reserved Dualism in Cities (continued) Informal Sector – Street vendors, letter writing, knife sharpening, your weight, recycling, prostitution, snake charming, mechanics, carpenters, barbers, personal servants, – Labor intensive – Unorganized, unregulated, mostly legal – Often, Self- or Family-employed – Destination for many (most) migrants

Copyright © 2009 Pearson Addison-Wesley. All rights reserved The Harris-Todaro Model A verbal description of the Todaro model – Migration is a rational decision – The decision depends on expected rather than actual wage differentials – The probability of obtaining a formal sector job is inversely related to the urban unemployment rate – High rates of migration are outcomes of rural urban imbalances A Diagrammatic Presentation

Copyright © 2009 Pearson Addison-Wesley. All rights reserved Table 7.1 Population of the Largest and Second-Largest Cities in Selected Countries (millions)

Copyright © 2009 Pearson Addison-Wesley. All rights reserved Are LDC Cities “Too Big?” Marx and Engels: – It is in cities that people would come to understand that, in capitalists societies, “all that is solid melts into air.” – Urban-industrial development is a necessary stage in historical development, leading to upheavals of peasants and proletarians. Gareth A. Jones and Stuart Corbridge (2010),“The Continuing Debate about Urban Bias” Progress in Development Studies 10-1:1-18

Copyright © 2009 Pearson Addison-Wesley. All rights reserved Are LDC Cities “Too Big?” Tostoy, Blake, Rushkin: – “The country-side is paradise,” approximately. Gandhi: – “hospitals are institutions for propagating sin” – Railways are the “carriers of plague germs” which “increase the frequency of famines” – “machinery is like a snake-hole;” the source of Europeans’ enslavement of themselves – Good conduct can only be nurtured in villages

Copyright © 2009 Pearson Addison-Wesley. All rights reserved Are LDC Cities “Too Big?” Jacobs (1969): “Without cities, we would all be poor.” World Bank (2000): “Levels of urbanization and GDP per capita are closely and positively related.” Gapminder.org

Copyright © 2009 Pearson Addison-Wesley. All rights reserved Are LDC Cities “Too Big?” There is tremendous poverty (squalor) in the shanty towns of cities. – Yes, but people still choose to move there, indicating how much worse conditions are in the rural areas.

Copyright © 2009 Pearson Addison-Wesley. All rights reserved Are LDC Cities “Too Big?” The Todaro-Smith:rural-urban migration is greater than the urban areas’ abilities to create jobs and provide social services But Hans Rosling says, it is less expensive to provide health and education (Chapter 8) in urban areas than in dispersed rural areas – Example: Montana

Copyright © 2009 Pearson Addison-Wesley. All rights reserved Are LDC Cities “Too Big?” Todaro-Smith: Development policies have been characterized by an “Urban Bias” – Bulk of infrastructure investment going to cities (but that’s where the growth is) – Wage rates set artificially high in urban areas (yes in the formal sector; no in informal sector) – Ag prices set artificially low (yes, in 1950s-70s) – But most of these price distortions have been removed since the 1980s

Copyright © 2009 Pearson Addison-Wesley. All rights reserved Are LDC Cities “Too Big?” Todaro-Smith: Urban Bias results from the unequal political power between urban and rural areas. – Cities more educated, richer – But rural elites (at least) still have substantial influence (“voice”), especially in democracies (Montana, India: ag subsidies for water, power) Economics: Invest where social rate of return (benefit-cost ratio) is highest

Copyright © 2009 Pearson Addison-Wesley. All rights reserved Policies to Slow Migration Doug’s Note: Policies based on the premise that migration should be reduced Five Policy Implications – Reduction of urban “bias” in development – Higher education fosters increased migration and unemployment (Doug: so halt education?) – Wage subsidies can be counterproductive – Programs of integrated rural development (Doug: Cost-benefit?)

Copyright © 2009 Pearson Addison-Wesley. All rights reserved Policies to Slow Migration Create a urban-rural balance (Doug: that’s what migration does) Expand small, labor intensive industries (C-B?) Eliminate factor-price distortion (Doug: Yes!) Choose appropriate technologies (Doug: Mostly private sector) Modify the linkage between education and employment (Doug: Hire least qualified?) Reduce population growth (Doug: Done) Decentralize authority

Copyright © 2009 Pearson Addison-Wesley. All rights reserved Case Study: India

Copyright © 2009 Pearson Addison-Wesley. All rights reserved Banerjee: A Case Study of Delhi Earnings in Formal sector (only) 9% greater than in Informal sector, controlling for age, education, etc. 14% of Informal sector workers are non- wage (self- or family-employed) Non-wage Informal sector workers earn 47% more than Formal sector workers

Copyright © 2009 Pearson Addison-Wesley. All rights reserved Banerjee - 2 Movement from Informal to Formal Sector: – % of rural migrants into the Informal sector moved into Formal sector after 1 year – Rate of entry from Informal sector into Formal sector was 1/6 to 1/3 that of rate of direct entry into Formal sector from outside the area 2/3 of entrants to Formal sector found their jobs through personal contacts

Copyright © 2009 Pearson Addison-Wesley. All rights reserved Banerjee - 3 Most migrants were attracted by Informal sector work, rather than the possibility of being hired into the Formal sector Duration of unemployment after migration is short – 64% find work within a week – Average waiting time for first job = 17 days

Copyright © 2009 Pearson Addison-Wesley. All rights reserved Banerjee - 4 Migrants kept close ties to rural roots – 75% visit their rural villages – 2/3 remit part of income – Average Remittance = 23% of income => Modify Harris-Todaro model to take account of Informal sector; low unemployment

Copyright © 2009 Pearson Addison-Wesley. All rights reserved Case Study: Botswana

Copyright © 2009 Pearson Addison-Wesley. All rights reserved Lucas: Migration amongst the Batswana Urban earnings much higher than rural earnings (68% higher for males) – But differential is much less when control for education and experience More likely to migrate if: – Higher expected earnings – Higher probability of employment - Migration is economically rational

Copyright © 2009 Pearson Addison-Wesley. All rights reserved Lucas - 2 Earnings rise with time in urban center – Not because of shift to Formal sector – Rather, because of pay increases within the Informal sector => Modify Harris-Todaro model to take account of Informal sector; low unemployment
