Researchers have assumed that large ownership stakes held by institutional
investors grant them power to influence R&D investments, We found that owne
rship alone was insufficient and that institutions resorted to activism to
influence R&D investments. Institutional activism increased R&D inputs over
both the short and long terms. The nature of the activism and the strategi
c context of the R&D investment moderated the relationship. Further, R&D in
puts mediated the effect of activism on R&D outputs.
