National Income Identity
Y = C + I + G + NX. The accounting truism that total output (Y, real GDP) equals the sum of consumption (C), investment (I), government spending (G), and net exports (NX = exports minus imports). The identity holds every period by construction -- every dollar of output must be bought by someone in one of those four buckets. The identity is the constraint that every macro policy debate runs into: any claim that all four components can move favorably at once without something else giving must be reconciled with the arithmetic.
