Industrial development in cities
- Journal of Political Economy
, 1995
"... This paper uses data for eight manufacturing industries in 1970 and 1987 to test for and characterize dynamic production externalities in cities. We find evidence of both MAR externalities, which are associ-ated with past own industry employment concentration, and Jacobs externalities, which are ass ..."

with notions of urban specialization and product cycles: new industries prosper in large, diverse metropolitan areas, but with maturity, production de-centralizes to smaller, more specialized cities. For mature industries, there is also a high degree of persistence in individual employment patterns across
A theory of urban growth,
- Journal of Political Economy
, 1999
"... In an economy experiencing endogenous economic growth and exogenous population growth, we explore two main themes: how urbanization affects efficiency of the growth process and how growth affects patterns of urbanization. Localized information spillovers promote agglomeration and human capital accu ..."
