Secular stagnation: The time for one-armed policy is over: Stagnation is gripping several of the world’s largest economies and many view this as secular, not transient. This column argues that many economies need both demand-side stimulus and supply-side reform to close the output gap and restore potential-output growth. A combined monetary-fiscal stimulus – i.e. helicopter money – is needed to close the output gap, and this should be accompanied with extensive debt restructuring, policies to halt rising inequality, and additional public infrastructure investment.
