Three places

• Sriperumbudur. A town of about 100 thousand on the Chennai-Bangalore highway– In 1991, a village where India’s prime minister was

assassinated. – By 2006, Hyundai had produced one million cars there.

• Shenzhen. A city of 7 million near Guangzhou and Hong Kong– In 1980, not much more than a fishing village– By 2006, its port shipped exports greater than all of

India’s.• Seoul. A metropolis of 12 million, for many years

mainland Asia’s most prosperous city– In 1970, a squalid slum-ridden place.– By 2006, the largest originator of patents after the US,

Germany, Japan and Taiwan (China).

The 2009 WDR

Chapters 1, 4 and 7 develop an Urbanization Strategy

An Urbanization Strategy

• Should be realistic– Must recognize some stylized facts observed

for early, recent, and late urbanizers

• Should be rigorous– Must be informed by economic analysis that

identifies the drivers of these changes

• Should be implementable– Must identify a sequenced set of public policies

for places at different stages of urbanization

The Elements of an Urbanization Strategy

1. Recognize stylized facts• A summary of Chapter 1: Density.

2. Utilize insights from analysis• A summary of Chapter 4: Scale Economies

and Agglomeration.

3. Identify practical policies• A summary of Chapter 7: Policies for an

Inclusive Urbanization.

The Facts

• Urbanization is fastest at low income levels.– Because the sectoral transformation from

agriculture to industry happens early. • Today’s urbanization is not

unprecedented. – The pace and pattern of urbanization is similar for

early, middle, and late developers.• Portfolios of settlements tend to be

stable.– Metropolises, cities, and towns appear to serve

fundamental economic functions.

Urbanization happens early

Much of urbanization happens before countries get to $5,000 per capita

The pace of urbanization has not changed much

Urbanization’s speed is not different from that in the 19th century

Source: WDR 2009, Chapter 1.

Nor has its distribution

The relative size distribution of urban settlements is stable over time

Primate cities are similar

A rapid rise in size, then a leveling off

What is different? Size

The absolute size of the world’s largest cities is much larger today

What is not? Slums

“The first encampments of Baltimore’s poor were at the water’s edge. Time and again, outbreaks of yellow fever, malaria, cholera, typhoid fever swept the town. By the 1890s, Polish immigrants had supplanted the Irish and Germans, creating a ghetto of a new dimension.”

“In the 15 years between 1930 and the end of the war, the population of Singapore doubled to a million people. The physical condition of much of the existing housing was dismal.”

“The houses are poky and ugly, and insanitary and comfortless …distributed in incredibly filthy slums” in London. --George Orwell

Early, middle, and later urbanizers all had slums

Slums have precedents

“Although this is a hugely expensive area in Paris to live today, in Victor Hugo’s day it was a slum area, close to the Bastille Prison.”

Melbourne's most infamous slum, Little Bourke Street, … by the 1880s was completely filled up with all kinds of filth comprising

garbage tips, putrid liquid, straw rags, and other rubbish… “

“Katajanokka’s transformation from a low-income housing area of Helsinki. A former slum had become a prestigious residential area for the privileged classes.”

Early, middle, and later urbanizers all had slums

Urbanization is messy, but necessary

The Analysis

• Human settlements serve market needs.– Just as firms and farms provide goods and

services, settlements provide services too.

• Urban settlements are complements, not substitutes.– Most countries need a full complement of

settlements.

• Policies should address function, not size, of settlements.– Manage the full portfolio of places.

Settlements serve different market needs

• Towns and small cities allow firms and farms to exploit internal scale economies, which are low in light and high in heavy industries.

• Medium-sized cities facilitate localization economies which arise from sharing inputs and close competition among firms within the industry.

• Metropolises facilitate urbanization economies which come from industrial and cultural diversity that fosters innovation.

The Policies• Recognizing complementary functions of

places helps to make urbanization inclusive.– Principle: maximize agglomeration economies through

economic integration.• Policies become complex as urbanization

advances.– Principle: More policy instruments are needed in places

where urbanization is advanced than where it has just begun.

• Prioritization helps to facilitate inclusive urbanization at all stages of development.

– Principle: Start with common institutions, then also connective infrastructure, and only then targeted interventions.

Integration gets harder…

…. as urbanization advances, and more policy instruments are needed

Institutions and infrastructure to encourage density and reduce distance in Bucaramanga, Colombia

An Urban Strategy

• Indicator: Urban shares of 25 to 50 percent

• Priority: Neutrality between rural and urban areas

• Instrument: Spatially blind “institutions”

1. Provide basic social services such as schooling, sanitation, streets and security

2. Ensure functional rural and urban land markets

• Principal responsibility: Central government.

For areas of incipient urbanization:

Areas in Korea

An Urban Strategy

• Indicator: Urban shares of between 50 to 75 percent

• Priority: Connectivity between urban and rural areas, and within urban areas.

• Instruments: Institutions, and spatially connective infrastructure

1. Provide basic social services 2. Ensure functional land markets3. Invest in rural-urban and inter-urban infrastructure

• Principal responsibilities: Central and state governments

For areas with intermediate urbanization:

Changsha in China

An Urban Strategy

• Indicator: Urban shares of >75 percent• Priority: Livability of urban areas. • Instruments: Institutions, infrastructure,

and spatially targeted interventions1. Institute basic social services and ensure

functional land markets2. Invest in rural-urban and inter-urban

infrastructure3. Intervene to integrate slums and improve the

environment• Principal responsibilities: Central,

state, and local governments

For areas with advanced urbanization:

Bogota in Colombia

Institutions Infrastructure Interventions

Calibrating the Policy Response

• A large part of urbanization is over by the time a country reaches upper middle income—viz., levels of per capita income of about $3,500.

• The relationship between income and urbanization is not different for early and later developers.

• The relative size of urban settlements within a country is similar for countries at different levels of income, and so is stable over time.

Must recognize stylized facts

• Towns like Sriperumbudur enable firms and farms to exploit the advantages that come with size— “internal scale economies”

• Cities like Shenzhen allow firms in similar industries to localize and become efficient—”localization economies”

• Metropolises like Seoul encourage learning and innovation that comes from industrial diversity—”urbanization economies”

Must be based on rigorous analysis

• Incipient urbanizers should lay the institutional groundwork for the provision of basic and social services and to ensure functional land markets, in both rural and urban areas.

• Intermediate stages of urbanization require, in addition, investments in connective infrastructure to widen access to advantages of growing economic density.

• Advanced urbanization often requires—in addition to institutions and infrastructure—place-based interventions such as slum development programs.

Must identify policy priorities

Conclusion

• Recognize that urbanization is necessary.– Don’t fight, facilitate.

• Recognize that urbanization becomes more complex as it advances.– First the institutions, then the infrastructure, then

targeted interventions where necessary.

• Recognize that urbanization will not be clean and orderly.– The goal should be an inclusive urbanization.
