Prior studies of the guns-versus-butter trade-off have focused on total military expenditures and sub-components of welfare spending (education, health, and housing). I extend the analysis to include the major sub-components of the defense budget. The results are consistent with Clayton's; Domke, Eichenberg, and Kelleher's; and Russett's findings of a lack of defense-welfare trade-off in the 1947–80 era but reveal very specific trade-offs during the Reagan years
