Notes:
Standard errors in parentheses (*** p<0.01, ** p<0.05, * p<0.1)
Agricultural productivity is defined as cereal yield in kilograms per hectare times hectares per capita. The interaction between
agricultural and population has demeaned the population in the given year so that the raw coefficient on agricultural productivity can be
interpreted as the impact of agricultural productivity at the mean level of population. Data comes from the World Bank. Standard errors
are in parentheses. A constant is included in the regression but not reported.

Do Cities Increase Productivity?
• Random Shocks to Location for Individuals
– Roots in the individual fixed effect literature
– Similarities with Randomizing Across Peers
– Doesn’t deal with omitted place level factors
• Random Shocks to the Density Level
– If long term, these must be orthogonal to current
productivity (Combes et al. 2010)
– Or taking advantage of high frequency variation
(Greenstone, Hornbeck, Moretti)
• An alternative is to estimate the flow of ideas within a
network (Duflo and Saez, 2003)
• Real estate prices as a sign of WTP for proximity

Policy Related Questions
• Explicit Spatial Policies
– Should be city sizes be limited? Optimal city size?
• Investment in Infrastructure
– Roads and railroads but endogeneity is difficult
• Education and human capital spillovers
– Old questions remain (primary vs. secondary)
– New crop of great experimental work.
• Regulation, credit market, labor market matching
questions all relate to cities.

Waste and Fraud in Infrastructure:
The Institutional Challenge
Author: Branille
Engineering vs. Economics
Transportation and Congestion
• The traditional literature used engineering estimates
and engaged in cost-benefit analysis
– Fundamental conclusion is “bus good; train bad”
• A newer literature uses cross-metropolitan area
estimates to determine the impact of new
infrastructure projects.
– Baum-Snow (military map) on suburbanization
– Duranton-Turner on the fundamental law of highway
traffic and impact of roads on MSA gdp
• A parallel literature in developing economies
– Banerjee, Duflo and Qian (2012).
• Requires the exogenous location of infrastructure

Housing Markets,
Property Rights and Regulation
• Successful cities have high land costs which translates into
high costs of living.
– Housing costs are mediated by levels of regulation
• Impact of property ownership on outcomes (DeSoto, Erica
Field) through self-protection or ability to finance new
investment.
• Impact of structure on outcomes through health– the bore
holes problem and the Tenements law.
• The Western pattern was that property rights were
developed first (12th-18th centuries) but regulation
followed. Not so in the developing world.
• Large unregulated communities with dimly defined
property rights.

A conservative estimate: In many of the 35 major cities by 2005, average
annual disposable income is worth around 2-3 square meters (20-30 square
feet) of housing . It is even worse now.

Fact 3 (not so obvious):
Prices are way higher than physical costs of construction
