You can lead a horse to liquidity, but you can’t make it drink. In a world where private aggregate demand is weak and unconventional monetary policy eventually becomes like pushing on a string, the case for slower fiscal consolidation and productive public infrastructure spending is compelling.
Such spending offers returns that are certainly higher than the low interest rates that most advanced economies face today, and infrastructure needs are massive in both advanced and emerging economies (with the exception of China, which has overinvested in infrastructure). Moreover, public investment works on both the demand and supply sides. It not only boosts aggregate demand directly; it also expands potential output by increasing the stock of productivity-boosting capital. - in project syndicate
