Public investment key to escaping crisis: Summers

Larry Summers told the BBC that central banks are going to become "less relevant", as interest rates are going to be near zero for much of the time.
"Fiscal policies are going to be more important in supporting economic expansion," he said.
"And public investment policies are going to play a larger part."
Mr Summers, who is now an economic adviser to Joe Biden's presidential campaign, told Radio 4's The World This Weekend programme that "for those with an agenda around infrastructure, there's huge opportunity in this moment".
Without a doubt, there will be voices right now raising warnings of the political dangers and tax implications of such a growth in state intervention, but none of the economists The World This Weekend spoke to were among them.

For some on the left, the inevitability of more government spending - on both benefits and big job-creating projects - is an opportunity.
The prospect has certainly cheered up the markets, with a recent rally on Wall Street.
But Professor Mariana Mazzucato, Director of the Institute for Innovation and Public Purpose at University College London (UCL), says it is vital that any public spending project is well-focused.

Government has the 'upper hand'

"If we keep just arriving to the problem once the problem presents itself, so from one crisis to another - the financial crisis, the climate crisis, the health crisis - we're not going to get out of this constant crisis mode," she said.
"Most of what governments are currently doing worldwide, the trillions that are being thrown at the problem globally, is really just correcting for a problem."
Instead, she says, we should "structure that immediate short-term remedy with a long-run kind of vision" of what kind of economy we would like to create afterwards.
"This is the moment for government to do that, because it has the upper hand," she added
Most economists warn of a phenomena they call "secular stagnation" - a long-term lack of growth.
This can frighten off both consumers and investors, leading to a lack of investment and innovation that spirals down into greater unemployment and poverty. Allianz's chief economic advisor Mohamed El Erian says it is a danger which needs to be avoided.
"You need to win the war against a health threat and you need to win the war against an economic depression, but you also need to win the peace of sustained, high and inclusive growth… I worry that we will end up winning the war, but we may fail in winning the peace," he told the BBC.
"Difficult decisions have to be made early on as to how you allocate the relief measures you have…what some developing countries are discovering is they simply can't replay the playbook that has been used in the richer countries - they have to come up with something different that recognises that they're in there for the long haul."

Just in time

Well before the crisis, the idea of a globally-linked economy was, if not under threat, then being questioned - did it benefit very few, to the detriment of millions?
That was one of the pressures behind the wave of new nationalism, and with it, talks of new barriers to protect individual countries' economies against foreign competition.
The economists the BBC spoke to are agreed there will be one big change in supply lines following the pandemic - "just in time" will be replaced by "just in case".
Manufacturers will build in greater redundancy and look to buying vital components closer to home, but active barriers against world trade are a different story.

Gerard Lyons, chief economist to Boris Johnson when he was Mayor of London and a high profile supporter of Brexit, said such spending is affordable: "Clearly, there is a need at some stage to bring government debt down, in terms of the size of its economy, as we did after the Second World War. But the key thing is that low inflation, low rates and low yields allows the government to sustain a much higher level of borrowing after this crisis."
