"Walking And Chewing Gum"
Martin Wolf explains to deficit hawks that tightening fiscal policy too early could cause more problems in global markets.
Despite the most aggressive monetary policy ever, private sectors moved into huge surpluses. Monetary policy was “pushing on a string”. The fiscal offsets – overwhelmingly due to built-in fiscal stabilisers, not the discretionary stimulus – helped sustain demand in the crisis. But they were insufficient, even with monetary support, to prevent deep recessions. The argument that stimulus was unnecessary is hard to accept. It is easier to believe it was too small, albeit also ill-targeted.
So how quickly should deficits be eliminated? We must recognise the danger here: cutting public spending will not automatically raise private spending. The attempted reduction in the structural deficit might lead, instead, to a rise in cyclical fiscal deficits, which would be running to stand still, or to a reduction in the private surpluses only because income fell even faster than spending. Either outcome would be grim. Yet neither can be ruled out.
As long as output remains depressed, the fiscal support is most unlikely to be inflationary. Nor will it crowd out the private sector: it is more likely to crowd it in. The big question, then, is whether deficits can be financed. My answer is: yes. Remember that so long as the private sector runs financial surpluses it must buy claims on the public sector, unless the developed world as a whole is about to move into huge external surpluses.
Deficits are a real problem, just not now. It’s clear that we should reassure private investors and financial markets by setting up long-term policies for controlling the deficit that don’t depress demand in the short-term. A VAT would be one obvious revenue side solution. Controlling health care costs is the biggest on the spending side. The good news is that the best way to curb the deficit is to enact policies that promote economic growth now. Fiscal restraint now isn’t one of those policies.
