In 16Q3 and in 16Q4, the combined addition to real US GDP by all levels of government (federal, state and local) was 0.07 and 0.06 of a percentage point respectively. That was weak. Government spending should consistently contribute roughly 0.40 of a percentage point to GDP growth. More than that, and government spending is fiscally stimulative, less than that, as has been the case of late, is fiscally contractionary.
