It’s not often center-left economists disagree with each other – let alone get into a stoush. But it’s what happened over the last week.
On February 5 former US Treasury Secretary and National Economic Council Chair Larry Summers published an opinion piece suggesting the Biden administration’s US$1.9 trillion bill might be “too big.â€
MIT economics professor and former International Monetary Fund chief economist Olivier Blanchard backed Summers on Twitter, saying:
I am known as a dove [one who supports low interest rates and generous government assistance] I believe that the absolute priority is to protect people and firms affected by Covid. Still, I agree with Summers. The $1.9 trillion program could overheat the economy so badly as to be counterproductive. Protection can be achieved with less.
This all caused a good deal of consternation within the Biden administration, and led the current Treasury Secretary Janet Yellen to push back hard, saying “we are in a huge hole with respect to the job market.â€
Former chair of the Council of Economic Advisers Austan Goolsbee backed Yellen and Biden, saying:
further delay in approving a larger relief program would be a mistake. That ‘wait and see’ approach has proved to be deeply wrong since the pandemic began. The issue is what I have called the No. 1 rule of virus economics: If you want to help the economy, you have to stop the virus.
So who’s right?
The core of Summers’ argument is that, according to the Congressional Budget Office, the economy is running $50 billion a month below it’s potential, an output gap that will decline to $20 billion a month over the course of the year.
The improvement is in part because of a $900 billion package approved in December under the Trump administration.
Summers points out the Biden administration’s extra $1.9 trillion package would be three times larger than the projected shortfall in output.
As a result, it would “set off inflationary pressures of a kind we have not seen in a generation, with consequences for the dollar and financial stabilityâ€.
As well, a package so large might preclude the future spending on infrastructure and productivity-enhancing measures that will be needed to overcome the sluggish growth (“secular stagnationâ€) identified by Summers before Covid-19.
Those who support the Biden plan argue it isn’t a traditional stimulus package of the kind Obama enacted in 2009 to get the economy out of recession. Covid is more like a natural disaster.
The spending package is akin to disaster relief, and it’s unwise to skimp on disaster relief.
That said, about a quarter of the $1.9 trillion will be spent on sending $1,400 cheques to individuals, on top of the $600 cheques sent as part of the earlier package. That part looks more like a traditional stimulus measure than disaster relief.
So, who’s right?
The central controversy is whether the output gap is large enough to accommodate the Biden spending without undue inflationary pressure.
Financial journalist Matt Yglesias has looked to the markets for an answer.
He points out that:
because the government sells both regular bonds and inflation-protected bonds, if you look at the difference between the interest rate on a regular bond and the interest rate on an inflation-protected bond, you get a market estimate of how much inflation is expected in the future
The resulting graph shows inflation expectations have moved back into the Federal Reserve’s target band of 2-3%.
What this means depends on what the market thinks will happen to the package.
If it thinks the full package will be enacted, it looks like an endorsement. The package should be enough to get inflation back to the target, but not enough to accelerate it beyond that.
But if it thinks only a fraction will be enacted – maybe half or two-thirds – but what turns out to be enacted is the full package, it might mean the market expects inflation to run out of control, just as Summers and Blanchard suggest.
So the markets provide clues, but no answer. It will give us a better steer when we are certain how much of the package will become a reality.
For now, it’s hard to tell who’s right: Summers and Blanchard, or the Biden administration.
Given that the US Federal Reserve would put the brakes on inflation if it did start to take off, it’s probably wisest to back Biden and run the risk of spending too big rather than too small.
