This article critically reviews the literature on the economic benefits of
publicly funded basic research. In that literature, three main methodologic
al approaches have been adopted - econometric studies, surveys and case stu
dies. Econometric studies are subject to certain methodological limitations
but they suggest that the economic benefits are very substantial. These st
udies have also highlighted the importance of spillovers and the existence
of localisation effects in research. From the literature based on surveys a
nd on case studies, it is clear that, the benefits from public investment i
n basic research can take a variety of forms. We classify these into six ma
in categories, reviewing the evidence on the nature and extent of each type
. The relative importance of these different forms of benefit apparently va
ries with scientific field, technology and industrial sector. Consequently,
no simple model of the economic benefits from basic research is possible.
We reconsider the rationale for government funding of basic research, argui
ng that the traditional 'market failure' justification needs to be extended
to take account of these different forms of benefit from basic research. T
he article concludes by identifying some of the policy implications that fo
llow from this review. (C) 2001 Elsevier Science B.V. All rights reserved.
