摘要：Densely populated areas tend to be more
productive. Of course, the cost of living and
producing in these locations is higher because
congestion raises the cost of scarce fixed
resources such as land. But despite the higher prices,
many people and businesses continue to live and work in
these areas. Why? One explanation is that these locations
have natural advantages, such as proximity to a river.
Another says that this concentration of households and
businesses by itself generates productivity advantages in
the form of agglomeration economies. In studying these
agglomeration economies, economists have pursued two
other questions. Do agglomeration economies exist and
how big are they? And what are the precise sources of
these agglomeration economies? In this article, Jeffrey
Lin describes the evidence for agglomeration economies
from job search and matching and then asks whether it
may be large enough to offer meaningful explanations for
differences in productivity and density.
