Summerhill’s social savings calculations are a piece of this argument,
ranging from 6 to 11 percent of GDP in 1913 on freight, and a surprisingly
large 4 percent for passenger service (versus, say, something on the order of
1.5 percent for Mexico). Summerhill’s conclusions, although cautious, point
to an obvious fact. In Latin America, railroads mattered for growth and, in
some places, they mattered a great deal. That this finding emerges should
perhaps not surprise, for the tradition of structuralist economic thinking
so long current in the region has always emphasized sluggish adjustments
in supply as a primary obstacle to economic development, and public, as
opposed to private enterprise as its agent. These putatively large returns to
railroad construction in the presence of insecure property rights, political
upheavals, and undeveloped capital markets go some way to explaining why
railroads as, so to speak, engines of economic growth, went nowhere for
many years: the divergence between private and social rates of return was
simply too great. Domestic investors, capital-constrained, and, perhaps,
alert to the true risks of investing, were unable or unwilling to seize the
opportunities offered. Foreign investors, inevitably cautious, regarded some
of these markets with great trepidation. For most of the nineteenth century,
or at least after default in 1827, the risk premium on Mexican bonds was
rarely less than 10 percentage points above the yield on British consols, and
when the yield on Mexican bonds did converge to the consol rate in 1887,it
was for the first time in nearly a quarter century. For Argentina, significantly,
the perceived risk was considerably lower, and, according to calculations by
Cort
´
es Conde, country risk was usually less than 10 percentage points after
1864,except in moments of severe strain. Hence, Argentina’s earlier start
in railroad construction, and a larger network in 1877 than Brazil, Chile,
Peru, and, of course, Mexico, which had almost nothing. Because the bulk
of railroad construction that occurred after 1870 depended on capital from
Great Britain, the United States, and France, the attitude of foreign investors
toward the principal railroad-building countries was, essentially, a decisive
consideration.
Colombia was somewhat different. Here, recent estimates by Mar
´
ıa
Te resa Ram
´
ırez for 1927 place the social savings for Colombia between
2 and 4 percent of GDP, by far the smallest estimate thus far for
Latin America. Perhaps the simplest explanation is that the measure of
social savings depends on the existence and cost of alternative means of
transportation. Because railroads were constructed with some delay in
Colombia, road and highway transport was already available, reducing the
share of coffee transported by railways and raising the responsiveness of
