On the Growth and Welfare Effects of Defense R&D

In the US, defense R&D share of GDP has decreased significantly since 1960. To analyze the implications on growth and welfare, we develop an R&D-based growth model that features the crowding-out and spillover effects of defense R&D on civilian R&D. The model also captures the effects of defense technology on (i) national security resembling consumption-type public goods and (ii) aggregate productivity via the spin-off effect resembling productive public goods. In this framework, economic growth is driven by market-based civilian R&D as in standard R&D-based growth models and government-financed public goods (i.e., defense R&D) as in Barro (1990). We find that defense R&D has an inverted-U effect on growth, and the growth-maximizing level of defense R&D is increasing in the spillover and spin-off effects. As for the welfare-maximizing level of defense R&D, it is increasing in the security-enhancing effect of defense technology, and there exists a critical degree of this security-enhancing effect below (above) which the welfare-maximizing level is below (above) the growth-maximizing level

Dot plots of nucmer alignments. Dot plots of Robertson, Fish Creek and Goon Nure sequences against the Shintoku reference sequence (A) and self alignment (B). Alignments were generated using nucmer. Reference alignments represent longest mutually consistent set (delta-filter -g), self alignments include all additional matches > 50 bp in length and 75% identify (delta-filter -i 75 -l 50). Purple lines represent primary or highest scoring matches, blue lines represent additional matches. (TIF 9120 kb
