Mainstream Keynesian economics is facing its last hurrah. The global fiscal stimulus championed last year by the Obama administration is coming undone, repudiated by the same Group of 20 that endorsed it last year. Now, against a backdrop of a widening sovereign debt crisis, we need to abandon short-term thinking in favour of the long-term investments needed for sustained recovery.
Keynesian stimulus was premised on four dubious propositions: that it was needed to prevent a global depression; that a short-run fiscal boost would jump-start the economy; that “shovel-ready projects” could combine short-term cyclical and long-term structural agendas; and, last, that the rapid rise of public debt occasioned by stimulus need not be a concern. That these ideas were so widely accepted was a testament to the perennial political attractiveness of tax cuts and spending increases.
In fact, the ubiquitous references last year to the Great Depression were glib; the policymakers had panicked. Adroit central banking could and would prevent depression. The hastily assembled stimulus packages were a throwback to naive Keynesianism. The relevant fact was that the US, UK, Ireland, Spain, Greece and others had over-borrowed for a decade, so a decline in consumption after 2007 was not an anomaly to be fought but an adjustment to be accepted.
