Overall, the model indicates that there are positive effects on R&D expenditure due to spillovers from peers and clients to companies that are located nearby (within 25 or 50km). Furthermore, R&D expenditure by academia also has a positive influence on a company’s R&D expenditure within state boundaries. However, R&D spending by government bodies appears to have the opposite effect, seemingly ‘crowding out’ private R&D spending.
The study has important policy implications, because it suggests that public support for R&D, whether to private firms through grants and/or tax incentives, or through funding of research in universities and other public institutions, results in benefits not only to the organisation receiving the direct support, but also to other firms and institutions more broadly.
Significantly, the modelling provides further evidence that Australia’s reputation for having a woefully low level of industry/research collaboration (which is based on one rather dubious OECD data point) is largely undeserved. I have previously observed that Australian companies clustered geographically close to major academic institutions tend to file more patent applications, while research by IP Australia has shown a healthy rate of patent applications naming industry and research partners as co-applicants from Australia when compared with other OECD nations. The Spillover paper supports this by showing a positive correlation between academic and industry R&D spending, particularly for companies and institutions located within the same state (and, in practice, probably more closely than this, although the paper does not break down academic R&D expenditure below state level).
I discuss further details of the model, and the paper’s key findings, later in this article. If this is all you are interested in, feel free to skip ahead. But first I would like to take the opportunity to explain the general process of econometric modelling for readers who may be interested in better understanding how economists think about the kinds of questions addressed by this paper, and how to interpret their results.
