This paper reports evidence of localized returns to the massive information
-processing technology (IT) investments made during the 1980s. It uses two
indicators of regional economic performance: (1) real per capita personal i
ncome growth; and (2) real output-per-worker growth. After introducing cont
rols for a variety of human capital variables and broader regional business
base and population dynamics, we find that the larger a region's installed
base of networked IT systems, the more vigorous were the industry-mix shif
ts underlying regional output-per-worker gains. However, this effect is pow
erfully mediated by regional economic scale. No evidence of IT-induced inco
me gains was found. These findings lend support for a reconsideration of th
e conventional wisdom that IT technologies have as their primary influence
the erosion of the significance of time, space and place in an economy. Ins
tead, the returns to such IT investments are powerfully mediated by their m
arked spatial distribution.
