论文摘要:

 

While many studies document that R&D investments significantly contribute to firm value, there

is very little existing research which investigates whether the reduction in R&D expenditures

creates any negative impact on firms’ performance. This paper examines long-term performance

following significant R&D decrease. We find that firms with large decline in R&D generate a

significantly positive abnormal stock return in the long-run. This return drift cannot be explained

by previously documented determinants of cross-section returns, such as size, book-to-market

ratio, momentum, accruals, asset growth and net share issuance. We explore three economic

motives behind R&D decrease – R&D spillover, managerial myopia and overinvestment – to

account for the associated abnormal returns. We find no compelling evidence to support either the

spillover or myopia explanation. Our results are most consistent with the overinvestment

hypothesis that firms cut down R&D investments to mitigate the agency problem. Firms with low

growth opportunities generate higher future returns than their R&D decrease counterparts. Also,

firms decrease their cost of capital after R&D decrease and these firms with declining cost of

capital outperform. Our results suggest that the market underestimates the decline in cost of

capital following R&D reduction.
