Title: Cities, Ideas and Housing
1Cities, Ideas and Housing
- Edward L. Glaeser
- Harvard University
2The Central Paradox
- Why is it that in an era in which transportation
and communication costs have virtually vanished,
cities have become more important than ever? - Urban resurgence is visible in high income
levels, robust housing prices, and a
concentration of innovation in urban areas.

4Urbanization Across the World
5The Hypothesis
- One major effect of globalization has been an
increase in being smart. - You become smart by being around other smart
people we are a social species. - Cities, like Boston and New York and London and
Bangalore make that possible. - The same death of distance that did so much to
hurt Detroit helped NYC.
6The Urban Role in Civilization
- Start with the basics clothing and food.
- By the time you get to our own country, it is
cheap enough to ship food that you get food
cities, but 1,000 years, cities like Bruges and
Florence were clothing cities specializing in
wool. - Urban density enabled markets to work and spread
human capital and shared machines.

8The Gifts of Urban Density
- Art in Flanders (van Eycks, Campin, Memling)
- Commercial patrons and learning
- Religion
- The Brethren of the Common Life (Adrian IV,
Erasmus, Martin Luther) - Education and Literacy
- Caxton and Gutenberg
- Political unrest and democracy (Coninck)
9The Problematic 20th Century
- The Automobile made public transportation
oriented cities seem somewhat obsolete. - The truck freed manufacturing from needing to
cluster around ports and rail stations. - Declining transport costs created a rise in
consumer cities over cities oriented around
productive advantages like waterways.

14The Rebirth of Boston, NYC
- Idea-oriented industries rose in places that were
once centers of manufacturing. - Finance in New York and an urban chain of ideas
- Understanding risk and return with data
- The sale of riskier assets (Milken)
- The use of risky assets to restructure companies
(KKR) - The nationwide sharing of risk (Ranieri and MBSs)
- The sale of data tools (Bloomberg)
- Finance, management consulting, computers,
biotech in Boston
15What Do They Make in Bangalore?
- The quintessential example of the flat world is
actually a hotbed of learning via proximity. - Milan thrives and Turin fades.
- Minneapolis excels and Cleveland doesnt.
- Birmingham reinvents itself (it always was an
intellectual polis) Manchester doesnt.

21What is good about urban poverty?
- Cities tend to contain a large number of poor
people, but that reflects urban strengths more
than urban weaknesses. - In places like Boston, there is opportunity,
ethnic networks, and life without cars. - Cities arent making people poor, they are
bringing them in. - Policies that are good to poor people in cities
will attract more of them and that is o.k. the
really problem is the artificial equality of
suburbs.
22Why are so many people still in the rustbelt?
- The rustbelt was built on manufacturing around
the waterways. - Erstwhile creative hubs like Detroit evolved into
goods producing machines, but declining transport
costs led manufacturing to move. - Now there is little obvious comparative advantage
to these places and the weather isnt great.

25Should we be trying to fight history?
- There are good economic reasons for these places
declines, government policy is ill equipped to
undo them and is often counter-productive. - Do we really want to push people to stay in
declining areas? - Often place-based efforts look much less
productive than people-based efforts (head start
26The Rise of the Consumer City
- While clusters of genius are more important than
ever, they are no longer tied down by productive
amenities - Increasingly, cities have formed in places where
people want to live. - At the same time, more attractive older cities
have become increasingly attractive to people who
like density.
27When are high real wages bad?

31The Rise of Reverse Commuting
32Are some cities becoming gateless gated
communities?
- Over the past 40 years, there has been a
revolution in property rights regarding
development, some of this is good, some is bad. - Suburbs, not cities, are the center of this.
- Still, a large number of cities are increasingly
making it harder to build. - This is where Jane Jacobs was wrong.

42What is good about sprawl?
- While some cities are thriving, Americans are
still moving to the car-oriented sunbelt and for
understandable reasons. - While cities do well for the rich and the poor,
car-based cities provide faster commutes, cheaper
homes (and goods) for middle income Americans. - Cities must do better in competing for this
segment of the population.

45Green Cities
- Urban residents are much less likely to drive
than their suburban counterparts. - Urban residents live in smaller homes that use
less energy. - Since we dont tax carbon properly, this means
that there are too few people in cities. - The environmental consequences of
environmentalism.
46Sources of CO2 Emissions
- Private Gasoline Consumption (Cars)
- Public Transportation Emissions
- Home Electricity
- Home Heating Natural Gas and Fuel Oil
47A Few Caveats
-
- We are not including anything about industry or
workplace. - We will use a 43 dollar per CO2 ton cost this is
highly debatable (about ½ Stern Report). - Scale it up or down as you like.
- Average vs. marginal homes matter, especially in
heating efficient.

50City-Suburb Differentials
- For each metropolitan area, we can also calculate
the difference between urban and suburban energy
usage. - Calculate gas usage by central city vs. suburb.
- Convert public transit by ridership using census
figures. - Calculate energy spending using the IPUMS for
central city vs. suburb.

52Towards a Level Playing Field
- Cities are important and while they should not be
subsidized, they do deserve a level playing
field. - Anti-urban bias 1 caring for the urban poor is
expensive and should be everyones
responsibility. - Anti-urban bias 2 failure to correct
environmental externalities - Anti-urban bias 3 failure to let cities grow.
