Abstract
Supply chain issues have garnered considerable attention during recent years, especially with the advent of the COVID-19 pandemic. Whereas many causes and effects of supply chains have been studied, this paper focuses on an aspect that has largely been ignored—the effects of supply chain constraints on research and development (R&D) spending. Using cross-country data from numerous countries over the past decade, we find support for our main hypothesis that supply chain constraints undermine R&D spending. However, different dimensions of the supply chain have quantitatively different effects on research spending. Interestingly, we find evidence of the legacy of supply chain issues from pre-pandemic days to impact more recent R&D spending. Finally, the main findings are robust to consideration of reverse causality issues. Implications for technology policy are discussed.

Notes
Branco et al. (2023) provide a careful analysis of the adverse effects of transport cost shocks on firm performance and firm behavior. They do not consider R&D spending, however.
Rashidi and Cullinane (2019) also provide a critique of the LogisticsPERF index.
Recall that higher values of the logistics variables imply better logistics performance – Table 1.
We double-checked the data to see whether there was any double-counting between Investment and R&D. Despite the lack of apparent overlap, some nations might be counting regular investment as R&D and vice versa.
Using appropriate caution in interpreting relative index scores, we see that the mean on overall globalization index is greater than that of its components (Table 2).
A part of the reason for the insignificance of the effect of lending rate might be that in some nations, R&D is partially subsidized, at least in some target sectors/projects, and firms do not face the full effects of prices or interest rates.
The low statistical significance could partly be due to the relatively small sample size (due to missing observations) in Table 6.
