It is now clear that to most observers that the use of monetary policy to stimulate major changes in economic activity in either direction is fraught. Central bankers in many nations have been pulling all sorts of policy ‘rabbits’ out of the hat over the last decade or more and their targets have not moved as much or in many cases in the direction they had hoped. Not only has this shown up the lack of credibility of mainstream macroeconomics but it is now leading to a major shift in policy thinking, which will tear down the neoliberal shibboleths that the use of fiscal policy as a counter-stabilisation tool is undesirable and ineffective. In effect, there is a realignment going on between policy responsibility and democratic accountability, something that the neoliberal forces worked hard to breach by placing primary responsibility onto the decisions of unelected and unaccountable monetary policy committees. And this shift is bringing new players to the fore who are intent on denying that even fiscal policy can stave off major downturns in non-government spending. These sort of attacks from a mainstream are unsurprising given its credibility is in tatters. But they are also coming from the self-proclaimed Left, who seem opposed to a reliance on nation states, and in the British context, this debate is caught up in the Brexit matter, where the Europhile Left are pulling any argument they can write down quickly enough to try to prevent Britain leaving the EU, as it appears it now will (and that couldn’t come quickly enough).
