Krugman's uncanny accuracy shows why more eyes should be on Japan

Abenomics is more that just a Japanese story.

Noah Smith has a post up examining Paul Krugman's remarkable record of accurate economic predictions. Ask "KrugTron the Invincible", as Smith dubs him, and he will point to his use of Keynesian economics for simple rule-of-thumb guesstimates, which then get cleaned up with his understanding of the problems of a liquidity trap. But Smith wonders if there's a more specific reason for Krugman's hit-rate:

Like Voltron before him, he's borrowing heavily from Japan.

See, I myself am fairly agnostic about Keynesian ideas. But I've expected nothing but low growth, low interest rates, and low inflation since 2008 (though I haven't been as confident about these things as Krugman, and am thus not in his class as a super-robot). I expected these things because of one simple proposition: We are like Japan.

Since its land bubble popped in 1990, Japan has had low inflation and low interest rates and low growth, even as government debt mounted and quantitative easing was tried. Paul Krugman was there. He watched Japan carefully, and he often states that it deeply affected his thinking. In fact, it might not be an exaggeration to say that watching Japan made Krugman the Keynesian he is today.

The comparison is, at the moment, more relevant to the US than the UK. Our problems are pretty clear: we slashed investment coming out of a recession, which put the brakes on recovery. Now that we're (slowly) putting our foot back on the accelerator, we can expect a return to growth – at least until deficit reduction becomes a priority again. Insofar as we have any macroeconomic phenomena confounding economists, it's positive news: our unemployment rate is significantly lower than it should be, given our anaemic recovery. That's been pegged on underemployment, productivity declines, and the government fiddling the figures, but it doesn't call for a wholesale reworking of economic theory.

The Japanese experience, however, does. Its "lost decade" – now well on the way to being twenty years long – has stubbornly resisted everything thrown at it so far. The pessimistic view is that it's just what happens when demographics turn sour: with an ageing society and migration too low to counteract it, the economy is retooling to serve the needs of retirees, for whom long-term growth isn't a priority.

But Abenomics, the name for the broad package of unconventional policy measures brought in by the government of Shinzo Abe, offers a ray of hope. And if any of those tools, which range from monetized nationalisation of industrial stock to explicitly targeting the stock market to performing one of the largest rounds of qualitative easing ever, work, then there's a meaningful plan of action for not just Japan, but the US as well.

If they don't, then hopefully it won't take America the same twenty years it's taken Japan to realise that business as usual just won't cut it.

Does the UK care enough about climate change to admit it is part of the problem?

The government’s energy policies make can make it hard to decipher its commitment to emissions reduction.

“People tell me it’s ridiculous to be flying for a climate change project but you have to get real with it, I mean I can’t cycle across the Southern ocean,” says Daniel Price, an environmental scientist from London. As founder of Pole-to-Paris, Price is about to complete a 17,000km bike ride from the Antarctic to the Arc de Triomphe.

Price came up with the idea in an effort to raise public awareness of COP21, the UN Climate Change Conference taking place in Paris next week. During the trip he’s faced a succession of set-backs: from the discovery that boats were prohibitively expensive, to diplomatic tensions scuppering his Russian visa plans. Yet the darkest moments were when he became overwhelmed by the magnitude of his own mission. “There were difficult times when I just thought, ‘What is the point of this’?” he says. “Cycling round the world is nowhere near enough to engage people.” 

As world leaders descend on Paris, many questions remain unanswered. Not least how much support developing nations will receive in tackling the effects of climate change. New research commissioned by Oxfam claims that such costs could rise to £1.7tn a year by 2050. But with cuts kicking in at home, the need to deliver “climate justice” abroad feels like a bigger ask than ever.

So does Britain really care enough about climate change to accept its full part in this burden? The government’s energy policies make can make it hard to decipher its commitment to emissions reduction. In September, however, it did pledge £5.8bn from the foreign aid fund to helping poorer nations combat climate change (twice that promised by China and the United States). And there’s evidence to suggest that we, as a public, may also care more than we think.

In America attitudes are much darker; in the dismissive words of Donald Trump “It’s called the weather”. Not least since, as a recent study proves, over the last twenty years corporations have systematically spread scepticism about the science. “The contrarian efforts have been so effective," says the author Justin Farrell, a Yale sociologist, "that they have made it difficult for ordinary Americans to even know who to trust.” 

And what about in China, the earth's biggest polluter? Single-party rule and the resulting lack of public discussion would seem to be favouring action on the environment. The government has recently promised to reach "peak" emissions by 2030, to quadruple solar installations, and to commit $3.1bn to help low-income countries adapt to the changing world. Christiana Figueres, the UN’s chief climate official, has even lauded the country for taking “undisputed leadership” on climate change mitigation.

Yet this surge of policy could mask the most troubling reality of all: that, when it comes to climate change, the Chinese are the least concerned citizenship in the world. Only 18 per cent of Chinese see the issue as a very serious problem, down 23 percentage points from five years ago, and 36 points behind the global median.

A new study by political economist Dr Alex Lo has concluded that the country’s reduced political debate could be to blame for the lack of concern. “In China popular environmentalism is biased towards immediate environmental threats”, such as desertification and pollution, Lo writes, “giving little impetus to a morally driven climate change movement”.

For the international community, all is well and good as long as the Chinese government continues along its current trajectory. But without an engaged public to hold it to account there’s always a chance its promises may fade into thin air.

So perhaps the UK’s tendency to moan about how hard it is to care about the (seemingly) remote impacts of climate change isn’t all bad. At least we know it is something worth moaning about. And perhaps we care more than we let on to each other.

Statistics published this summer by the Department of Energy and Climate Change reveal that three quarters of the British public support subsidies for renewable energy, despite only 10 per cent thinking that the figure is that high. “Even if the public think the consensus is not there, there are encouraging signs that it is,” says Liz Callegari, Head of Campaigns at WWF. “Concern for climate change is growing.”

As Price puts it, “You can think of climate change as this kind of marathon effort that we have to address and in Paris we just have to get people walking across the start line together”. Maybe then we will all be ready to run.
