Ricardian equivalence: a standalone construct

David Ricardo raised the proposition in his 1820 essay on the funding system, observing that a government can pay for a given amount of spending either by taxing now or by borrowing and taxing later, and that a taxpayer who foresees the future taxes needed to service and repay the debt should treat the two options as equivalent, though Ricardo himself doubted people would actually behave this way. Robert Barro formalised and revived the idea in his 1974 article Are government bonds net wealth?, showing that if households care about their heirs and leave bequests, the burden of the future taxes is passed forward across generations, so a deficit-financed tax cut is saved rather than spent and leaves total demand unchanged. On this account government bonds are not net wealth to the private sector, because every dollar borrowed is offset by the present value of the future taxes it implies. The proposition is distinctive as a benchmark for fiscal policy: it states the exact conditions under which the choice between taxing and borrowing has no effect on consumption, interest rates, or output, so that the ways real economies depart from those conditions (borrowing constraints, finite lifetimes without bequests, distortionary taxes, or shortsighted spending) become the channels through which deficits can matter.[1][2]
