Motivation
• Transportation technologies have been emphasized to be one of the
main causes behind the persistent decrease in transportation costs
(Hummels, 2007). Hence, understanding the causal impact
transportation technologies have on the economy is important.
However, the presence of endogeneity makes this task difficult.
• Railroads were a big shock to transportation costs between regions
and can help us to identify the causal effect of transport costs on
development and on outcomes such as population growth,
urbanization and specialization.
• As the reduction in transport costs is channeled through market
mechanisms, relative prices should play a crucial role in the
magnitude of the effects of railroads construction.

Our Paper
• We look at Latin America and construct a panel dataset of Chilean
departments spanning a sixty-year period of railroad construction
(1860-1920).
• Our paper estimates the causal impact railroads have on population
patterns and urbanization. In this sense, we are more related to the
literature on impacts and mechanisms.
• We suggest a novel mechanism for small open economies in which the
impact of railroads on population and specialization patterns depends
on the relevant relative prices –the real exchange rate– at the time of
construction of railroads. Related to Atack et al. (2008) and
Fajgelbaum and Redding (2014). Key difference: small open economy.

Preview of Strategy and Results
• We estimate the causal effect railroads have on urban population
using two different sources of exogenous variation in an instrumental
variables framework:
Straight lines (Banerjee et al. 2012).
2 Theoretical construction.
1
• Our empirical strategy complements the existing literature and is
particularly appealing for a panel dataset
• We find that a 1% increase in availability of railways causes an
average increase of about 12-15% increase in total, rural, and urban
population. We do not find that an increase average railroads
increase on patterns of specialization.

Preview of Strategy and Results
• However, we find that when the relative price of tradables to
non-tradables is high, railways construction does affect specialization
through a subsitution of agriculture for manufacturing employment
and, therefore, a decrease in urbanization.
• We use a simple theoretical model to rationalize these results.
• We focus our analysis on departments in the south, whose economy is
mainly based on agriculture. This also allows us to use the distinction
between urban and rural population as a proxy
• We argue that the economy’s aggregate real exchange rate, which we
use as a proxy for the relevant relative price, is largely exogenous to
these departments, who are a small share of the total economy, as it
is largely driven by mining activities in the north

Mining and the first railway connecting Copiapó and Caldera.
• Importance of Copiapó as mining city (Chañarcillo 1832).
• Obsolescence of old technologies (carts and mules).
• These railways encouraged following constructions.
2
Connecting Valparaiso and Santiago.
• Obsolescence of public roads and public pressure.
• 187 kilometere railroad connecting the port and the capital.

Transportation Costs
• Railroads brought a significant decrease in transportation costs
because:
Chile’s inability to transport goods through rivers.
2 Cold winter and flooding from rivers made transportation difficult.
3 Poor quality of roads.
4 Possibility of being victimized by bandits (Verniory, 2001).
1
• Before railroads freight between Valparaiso and Santiago was done
with forty ox carts, with capacity for fifty quintals, during a period of
6-12 days (costs $1–1.75). By railroad: 8 hours and cost $0.44-0.55.
• Passenger time decreased from 20 to 6 hours and costs from $10–20
to $2.5–5.

Data Construction
• Two historical sources to document the railroad construction:
1
2
Historical censuses (1865, 1875, 1885, 1895, 1907, and 1920).
Railroad construction: Espinoza (1897), Thompson and Angerstein
(1997), Alliende (2006) and others.
• From these sources we constructed a panel dataset of 45 departments
at 6 different periods.
• However, we exclude 10 departments located in the North of the
country: just related to mining and different gauge.
• In sum, 13,586 kilometers of railroads were constructed, but we will
only use 8,681 kilometers constructed from Valparaı́so to the south.
• For comparison: 4,500 km. in Perú and 24,000 km. in Brazil in a
similar period.

Economic Mechanisms
• What are the economic mechanisms linking a reduction in transport
costs and an increase in population?
• We now present the main ideas of a simple model that highlights
some mechanisms and also provides a new test related with the
relevance of the real exchange rate.

Theoretical model
• The impact of railroads goes mainly through a reduction in
transportation costs
• This reduces trade barriers, and allows regions to specialize in the
goods in which they have a comparative advantage
• Labor mobility plays a crucial role, as workers move across regions
and sectors to arbitrage real wage differences
• Given that most regions in our analysis have a comparative advantage
on agriculture, the allocation of labor between tradable and
non-tradable sectors will play a role in the relative growth of urban
and rural population

Theoretical model
• The overall impact of access to the railroad on a given a region will
depend on its specific impact on trade costs with the world economy
and the rest of the country (which might vary across regions) and
relevant prices

Model setup
• Consider a country with N agents and M different regions.
• Each region is endowed with L units of land .
• Land is equally owned by all agents, so per capita land holdings are
ML/N.
• There are 3 goods: agriculture (A), tradable manufactures (M ), and
services and non-tradable manufactures (S ).

28 / 1
Model setup
• Agricultural and manufacturing goods can be traded between regions,
and also with an international market with exogenous prices, pA∗ and
∗ .
pM
• Trade between regions and with the rest of the world is subject to
iceberg costs related to the transportation technology: consuming one
unit of good M (S ) produced in region i at region j implies shipping
(1 + δij ) units at origin.
• Services are non-tradable, and must be produced and consumed
within each region.
Forero, Gallego, González, & Tapia ( PUC-Chile, PUC-Chile

and
and
EHSpecialization

29 / 1
Model setup
• Within each region, there are 2 locations, rural and urban.
Agriculture is produced in the rural location, while manufacturing and
services are produced only in the urban location
• Each region is a small open economy

Agents and preferences
• Agents live where they work, and derive utility from the consumption of the 3 goods.
• Agents supply their labor inelastically in the labor market, and can choose freely where
to locate.
• The problem for any given agent agent can be written as:
Max U = U (cA (r , l ), cM (r , l ), cS (r , l )) = [cA (r , l )α + cA (r , l )α + cA (r , l )α ]
1
C (r ,l )
w (r , l ) + R = pM (r , l )cM (r , l ) + pA (r , l )cA (r , l ) + ps (r , l )cs (r , l ) + q (r , l )
, where r is region and l is sector.
• Free mobility implies that::
U (r , l ) = Ufor all r , l
where U is an equilibrium object

Technologies
• Goods are produced by perfectly competitive firms that face constant
returns to scale technologies on land and labor:
δA
yA,r = γAr LA
WA1−δA
δM
1−δM
WM
yM,r = γM LM
yS,r = ξ Lsδs Ws1−δs
, where γAr reflects the productivity of agricultural land in region L.
• We assume that δA > δM , δS (agriculture is more land intensive than
manufacturing or services)

• We also assume γAr > γM
• Firms maximize profits, taking as given final goods prices and factor
rental prices.

Equilibrium properties
• If regions trade, they specialize in the tradable good in which they
have a comparative advantage
• Real wages are fully equalized across regions, so workers are
indifferent about where to live
• A (non-observable) RER exists for each region

Propositions on the impact of railroads
• Proposition 1: Overall effect of access to railroads
Access to railroads for a given region, which reduces trade
costs, is akin to a productivity shock for firms, increasing the
demand for labor and real wages. New workers flow into the
region until equilibrium is restored

35 / 1
Propositions on the impact of railroads
• Proposition 2: Compositional effects of access to railroads
The compositional effect of population changes depends on
relative prices at the time in which railroads arrive. If the price
of tradables is relatively high, relatively more workers will flow
into agriculture and live in rural areas
Forero, Gallego, González, & Tapia ( PUC-Chile, PUC-Chile
Railroads
and
and
EHSpecialization
Clio Lab, UC Berkeley )
August 2014
36 / 1
Empirical implications
• (i) Access to railroads increases specialization in agriculture if the
nationwide relative price of tradables to non-tradables, as measured
by the nationwide RER, is high.
• (ii) The main mechanism to do that is a substitution between
agriculture and manufacturing production, in which crucially the
empirical measure of manufacturing has an important non-tradables
component
• (iii) Therefore, urbanization decreases when the relative price of
tradables to non-tradables is high, as workers move towards tradables,
in particular towards the one in which the economy has a competitive
advantage

Conclusions and future research
• We document that access to railroads had a significant impact on
•
•
•
•
overall population on Chile’s southern departments
Specialization patterns, and effects on the rate of urbanization, can
only be seen when we take into account the relative price of tradables
and non-tradables
We find no evidence of a significant effect of railroads on human
capital accumulation, public goods (government services) or foreign
inmigration
These results are consistent with the predictions on migration and
location decisions of a regional trade model with interregional labor
mobility
An interesting venue to explore in the future deals with population
dynamics and the importance of the timing of access to railroads
