Krugman: Can Japan pull it off?

Can Japan actually end decades of deflation?

Paul Krugman examines former Bank of England Monetary Policy Committee member Adam Posen's attempts to square the circle between his support for expansionary fiscal stimulus in Britain — where it hasn't happened — and opposition to the same in Japan — where it is apparently about to begin.

Posen wrote, in the Financial Times, that:

Mr Abe’s new fiscal stimulus initiative is therefore questionable. Not because another 2 per cent of GDP will be the proverbial tipping point on Japanese debt sustainability, for the factors protecting Japan from overt fiscal crisis remain. Nor because it will be ineffective; if anything, when combined with monetary expansion and a likely consumption tax rise in the near future, I expect its multiplier and thus short-run impact to be high.

The additional stimulus in Japan is counterproductive because it adds to the long-term costs without addressing Japan’s real problem: a return to deflation and an overvalued exchange rate.

Krugman is "a bit puzzled". He agrees that deflation is Japan's problem, because deflation forces short-term interest rates to bump against the lower bound. Since interest rates can't go below zero, that is, they are forced to remain slightly positive. That means that real interest rates — the nominal interest rate plus inflation — are forced to be significantly higher under deflation than they would be with mildly positive inflation, reducing the effectiveness of monetary policy.

So far, so macroeconomics 101. Where Krugman disagrees with Posen is how to break out of the deflation trap. Posen argues that unconventional monetary policy — quantitative easing and the like — can be enough. It's a monetary problem, so it ought to have monetary solutions. But Krugman argues that there may be a better way:

The credibility of a higher inflation target in the face of the deflationary bias of central bankers may well be best established by (a) reducing the central bank’s autonomy and (b) getting the central bank in the business of supporting — indeed, monetizing — government deficits, at least for a while. Gauti Eggertsson made this point long ago (pdf), pointing to Japan’s successful polices in the first half of the 30s as a clear example. Indeed, Gauti argued that having a large government debt can be a real advantage in such circumstances: efforts to raise expected inflation gain extra credibility if the government would clearly benefit in fiscal terms, and the central bank is sufficiently subordinated to elected officials that investors believe that it will take these fiscal benefits into account.

In other words, it all comes back to the question of central bank independence. If the government destroys that independence (even if it does it for paleo-conservative, nationalistic, reasons), and engineers a situation where inflation would make it better-off, then inflation expectations can be raised far higher than an independent central bank could ever do alone. Especially one which has so consistently failed to reverse the trend as the national bank of Japan.

After a year of division, a new centre is emerging in Labour

Clive Lewis, Lisa Nandy and Jonathan Reynolds show how factionalism is being transcended. 

On 26 September, Clive Lewis sat onstage at Labour’s conference in Liverpool and puffed out his cheeks in exasperation. He had just been informed that a line in his speech as shadow defence secretary committing the party to Trident renewal had been removed by Jeremy Corbyn’s office. Such was his annoyance that he was said to have later punched a wall in anger ("I punched no walls," he told me when we recently met). 

For Lewis, however, the feud proved to be a blessing. Hitherto hostile MPs hailed his pragmatism and deference to party unity (he is a long-standing opponent of Trident renewal). The former soldier also affirmed Labour’s support for Nato and for collective self-defence. “The values that underpin Nato are social-democratic values: liberty, democracy, freedom of expression,” Lewis, an early Corbyn ally, told me. “Let’s not forget, it was Clement Attlee and the New Deal Democrats who initiated and set up Nato. It’s about being in it to win it. It’s about winning the arguments inside Nato and making sure that it’s a force for good. Some people would say that’s impossible. I say you’ve got to be in it to be able to make those changes.”

In October, Lewis was replaced as shadow defence secretary by Nia Griffith and became shadow business secretary. Many regarded the appointment as a punishment. “Do I think there was an ulterior motive? I’ll never know,” Lewis said. “I’m confident that the reason I was moved – what I was told – is that they wanted me to be able to take on a big portfolio.”

Whatever the truth, Griffith has since said that Labour’s next general election manifesto will include a commitment to Trident renewal and will support multilateral, rather than unilateral, disarmament.

Many MPs had long feared that the divide between them and their leader would prove unbridgeable. Some contemplated standing on bespoke manifestos. Yet with little drama, Corbyn has retreated from a conflict that he could not win. Labour’s conference, at which the largely pro-Trident trade unions hold 50 per cent of the vote on policy and which the leader has vowed to respect, would never have endorsed unilateralism.

“Jeremy Corbyn deserves credit for that,” Lewis said. “Everyone understands that his position hasn’t changed. He still believes in unilateral disarmament . . . But he’s also a democrat, and he’s a pragmatist, despite what people say.”

In policy terms, at least, Labour will contest the next general election as a less divided party than many anticipated. As Corbyn’s team has long emphasised, there is unity around issues such as opposition to spending cuts and support for rail renationalisation. A new centre for Labour, embodied by Lewis, is emerging.

“When I became an MP,” the 45-year-old told me (he was elected in Norwich South in 2015), “to be anti-austerity, to say that cuts don’t work and they’re bad economics, meant you weren’t in touch with reality, and that you had no interest in winning elections. Within the space of 18 months, there’s now a growing consensus that cuts aren’t the way forward and that we need an industrial strategy.”

Theresa May’s support for new grammar schools and “hard Brexit” has given Labour MPs other issues to unite around. After Corbyn’s second landslide leadership victory, many of his opponents have reached the final stage of grief: acceptance. Others, as Lewis noted, are imbued with “an eager enthusiasm to make this work”. Contrary to some predictions, more than half of the 63 frontbenchers who resigned last summer have returned.

An emblematic figure is Jonathan Reynolds. The Liz Kendall supporter, who resigned as shadow transport minister in January 2016, has rejoined the front bench as shadow City minister. Earlier this year, Reynolds backed the introduction of a universal basic income, an idea that is now being explored by John McDonnell’s team (and that Barack Obama has called for “debate” on). In July, Reynolds and Lewis wrote a joint piece in support of proportional representation (PR), warning that without it “a more equal, democratic and sustainable society is less likely”.

Another advocate of PR is Lisa Nandy, the former shadow energy secretary and a friend of Lewis (on 26 October, along with Reynolds, they called for Labour to stand aside in the Richmond by-election to aid the Liberal Democrats). In the view of some, the defining divide in Labour is no longer between left and right but between open and closed. On one side are pluralists such as Lewis, Reynolds and Nandy, while on the other are tribalists such as Ian Lavery (pro-Corbyn) and John Spellar (anti-Corbyn).

The division stretches to the top, with McDonnell in favour and Corbyn opposed. “It’s a work in progress,” Lewis said of his efforts to convert the Labour leader. “There’s a growing movement of MPs who now either support PR or understand the growing necessity for it. They may not be quite there themselves, but they’re moving in that direction.”

At times since Corbyn became leader, the parliamentary party’s divisions have appeared to many to be insurmountable, even as the party in the country has grown and been inspired by Corbyn. Yet a new consensus is being forged in the PLP: anti-austerity, pro-Trident, pro-Nato and, increasingly, committed to political and constitutional reform. If there is any consolation for a becalmed Labour Party, it is that its European counterparts are faring little better. In Spain, France and Germany, an already divided left is further fragmenting.

But Labour is likely to both fight and survive the next general election as a united force. If Lewis can retain his seat in Norwich (he has a potentially vulnerable majority of 7,654), he could one day act as the bridge between the party’s “soft” and “hard” left. After a year of factional skirmishes, the common ground in which Labour’s future will be shaped is emerging.
