Recently, a new economic theory of growth (Romer 1986, 1990) that emph
asizes the importance of knowledge has been proposed. We extend this a
rgument to manufacturing plants by developing and testing a theory of
how investments in knowledge, as expressed in human capital and produc
tion technology, affect plant survival. Based on an event-history anal
yses of 97 manufacturing plants during the period from 1973 to 1987, w
e show that internal investments in knowledge are important for surviv
al and that knowledge and organization from are closely intertwined. W
e also find that the level of investment in research in the industry r
esults in higher survivability net of many other factors, confirming R
omer's basic thesis.
