Urban Development and Economic Growth in Bangladesh Somik Lall The World Bank Workshop on Growth & Employment, December 12, 2005 Outline • Bangladesh is predominantly rural but rapidly urbanizing • Across countries, urbanization is typically seen to accompany and lead economic growth (economic and institutional transformation) • Performance of individual cities is conditioned on local efforts as well as national / regional circumstances • Rapid population growth poses challenges for providing consumer and producer services • What strategies are useful for improving the contribution of the urbanization process to economic growth? Across countries, urbanization accompanies economic transformation 80 45 Urban population (% of total) 70 40 35 30 50 25 40 20 30 15 20 10 10 5 0 0 1965 1970 1975 1980 Labor force in agriculture (% of total) Source: World Development Indicators 2001 1985 1990 1995 Agriculture, value added (% of GDP) 1999 Urban % Agriculture % 60 And the Importance of agriculture diminishes as countries get richer Per capita GDP, 2000 100,000 10,000 Bangladesh 1,000 100 1 10 Agriculture, value added as percent of GDP, 2000 Source: World Bank Indicators (2000 data) 100 Share of urban population is rapidly increasing In Bangladesh Urban Population (%) 200 180 160 Population, millions 40 35 30 25 20 15 140 120 Total 100 Rural 80 Urban 60 2030 2015 2005 2000 0 1990 0 1980 20 1970 5 1960 40 1950 10 Source: United Nations World Urbanization Prospects 50 19 60 19 70 19 80 19 90 19 00 20 10 20 20 20 30 20 And much of the rural population is in close proximity to urban centers 100 90 Cumulative rural population by distance from different size towns 80 Percent 70 60 5,000 50 10,000 20,000 40 30 20 10 0 1 3 5 7 9 11 13 15 17 19 21 23 25 km Source: GIS calculations using WARPO/CEGIS data; based on 1991 census figures.

Implications of urban concentration (positives) • Benefits from economies of scale and agglomeration • Economic transformation with large cities leading manufacturing / industrial representation – Dhaka and Chittagong have over seven times the national representation of employment in garments and machinery. – Co-location of business and financial services boost firm level performance • Thick labor markets • Higher quality of life for residents as these cities can do better in proving local public goods and services Implications of excessive urban concentration (costs) • High prices for immobile factors (land and housing) • High commuting costs (leading to a segmented labor market), along with congestion and pollution diseconomies • Management failures lead to bottlenecks in infrastructure and service provision, thereby increasing production costs • This translates into lower welfare and overall economic performance Dhaka was ranked as one of the most polluted cities in the World , but PM2.5 concentrations have declined by 41% because of Two Stroke Phaseout Microgram/m3 350 300 250 200 150 100 50 0 PM2.5 Average Low satisfaction with public services Table 1: Satisfaction with Services (% of surveyed households) Services Dhaka Chittagong Khulna Rajshahi Police 2 0 1 2 Land Registration 2 1 10 4 Transport 7 3 19 6 Electricity Services 8 2 12 2 Judiciary 8 1 2 5 Health Care 11 4 18 9 Garbage Disposal 15 10 12 10 Sewerage/ 17 16 11 16 Education 21 5 28 12 Drinking Water 27 9 11 8 Sanitation Source: Proshikha (2002) Does the distorted urban system translate into lost opportunities for economic growth? • The central link between concentration and economic performance revolves around economies of scale. • If cities are too small, resources could be spread too thinly/evenly across cities and scale economies are not efficiently exploited. • However, if resources are over-concentrated in one or two excessively large cities, this raises costs of production of goods and lowers the quality of urban service provision. Table 1: The Effect on Annual Economic Growth Rates of Urban Concentration Low income ($1100) Medium income ($4900) High income ($13400) The optimal degree of urban primacy Loss in growth rate from excessive primacy (one standard deviation) Growth effect of a one standard deviation increase in road density in a country with excessive primacy .15 .25 .71 1.6 .23 .68 .23 1.6 .68 The table looks at a medium size country --national urban population of 22 million. Numbers for countries with urban populations of up to 50-60 million are similar. The first column calculates the degree of urban primacy that maximizes growth rates and steady state income levels. Error bands about this for medium or higher income countries are quite tight (standard error of .018). The growth losses of excessive primacy are high, although more so, as income rises. The role of transport investment (length of the national road system divided by national land area) is quite significant, particularly as countries enter middle income phases when deconcentration becomes critical. Growth implications for Bangladesh • In 2000, Urban population of 35 million; income per capita (1987 PP) of around $2100. • At this income level and urban scale, Bangladesh should have an ‘optimal’ primacy value of around 21 percent. • In practice, primacy is 32 percent -- 11 percent points higher than optimal values. • Based on Henderson’s estimates, primacy in Bangladesh is more than 2 standard deviations higher that the optimal range. • At this income range and urban scale, one standard deviation increase from optimal values reduces growth by 1 percent. A lower bound estimate of moving from two standard deviations above optimal value to the optimal value would increase GDP per capita growth rates by at least 2 percent points. How do we improve the contribution of the urbanization process to economic growth? • Improving management of the largest agglomerations • Dhaka (and other major cities) will continue to attract rapid population growth unless other urban centers become viable investment decisions. • Performance of major agglomerations need to be enhanced – Institutional reform – Provision of serviced land – Enhancement of own source revenues • Investments in inter regional infrastructure to deconcentrate standardized manufacturing How do we improve the contribution of the urbanization process to economic growth? • Developing alternate locations • Enhance the ability of Pourashavas to provide local services that are valued by local resident (but how?) • BMDF may be a useful vehicle for local infrastructure improvements • There may however be adverse welfare consequences if resources are spread too thinly or large cities are starved in order to stimulate smaller centers
