Why Japan needs Abenomics and Bitcoin faces a lost century

What do Japan's "lost decade" and the intractable problem facing bitcoin have in common? Deflation.

The Japanese economy is in a mess. It has been for a while now. GDP broke $5trn in 1996, but then fell, and stayed low for a decade and a half. It only reached that high again in 2011, after well over a decade with growth fluctuating between mildly positive and mildly negative : the "lost decade" of economists' nightmares.

That's the background against which the new prime minister Shinzo Abe is struggling. Abe, a right-wing popular nationalist, was elected on a platform of giving the Bank of Japan a kick up the arse and using unconventional methods to restore the country to growth. His motivations have been questioned repeatedly: some fear that he's just trying to provide a short term boost to the economy before the upcoming election to in country's upper house; others, that he's only enacting bold new policy due to a stubborn belief that whatever conventional economists say must be wrong. Sure, a stopped-clock is right twice a day, but that doesn't mean you want to base your economy on what it says.

But the unconventional policies have been enacted, and now we are just waiting to see their effect. Abe has launched a ¥10.3trn stimulus package; his economic minister has explicitly targeted the stock market, in an attempt to push it up by 17 per cent in just two months; and he's got his choice of central bank governor, with the appointment of the maverick Haruhiko Kuroda.

But if we want to find out whether these plans are working, we don't look at GDP. That's too slow to change, it's too subject to external shocks, and, most importantly, it's a symptom, not a cause.

The real culprit is inflation. Or rather, deflation.

The Japanese economy has had inflation hovering around 0 per cent – and more frequently below it than above it – for almost as long as it has had stagnation. And while the country has seen a return, of sorts, to GDP growth, inflation remains as stubbornly negative as ever. Even after Abe's reforms, the headline rate fell – down to -0.9 per cent, the fastest rate of deflation in three years. That's against a background, not only of all those impressively major reforms, but also a far more direct one: raising the inflation target of the bank of Japan from 1 to 2 per cent.

But why is deflation a problem? In the west we're used to fearing inflation, after the scarring experiences of the 1970s, when prices grew by 20 per cent in a year. And we all learned in school about hyperinflation in Weimar Germany, where the price of bread would be higher in the afternoon than it had been in the morning, and how that led to the rise of Hitler. (Incidentally, that connection is largely mythical; although it was responsible for prompting the creation of many extremist groups, hyperinflation was largely beaten by 1924, long before the Nazi party became a force in German politics.)

But deflation – prices getting lower year-on-year – sounds like a good thing. Who doesn't like getting richer without having to do anything?

The easiest way to explain the issues is to look at another economy which could almost have been invented to illustrate the problems with deflation: the trade in bitcoins.

Bitcoin, you may recall, is an anonymous, cryptographic, peer-to-peer digital currency. It's been in the news because of its astonishing boom-and-bust dynamics, with the value of one bitcoin increasing by 2000% in two months, then losing almost all of that in a week, and now slowly returning to a second high. But what's interesting here is that it's a currency with deflation built in from the very start.

There will only ever be 21 million bitcoins. Half of them have been made – "mined", in the parlance – already, and the rest will be released in decreasing quantity at ten minute intervals until 2140. Add in the fact that, although they can't be created in any other way, they can be destroyed just by deleting the file that holds them, and you've got a currency which is designed to deflate.

That deflation was made far worse in the last couple of months by the hyperbolic increase in the value of a bitcoin measured in any normal currency. If you can buy a bitcoin for $10, and then a month later it costs you $200, then that is largely inseparable from inflation, particularly since you still need to use real currency to eat, pay your rent, and buy your travelcard to get to work. It got so bad that some started talking about "hyperdeflation".

What all that deflation does is ensure that, if you hold bitcoins, it makes sense to wait until you're absolutely sure you need to make a purchase before you part with them. After all, if you're the guy who bought a pizza for 10,000 bitcoins in 2010, you may have got a tasty meal; but if you had held off, you would be $1.3m richer now.

And it gets worse when you look at things like investment. If you used bitcoins to buy equity in a startup, your expected return would have to be through the roof to even stand still compared to where you would expect to be if you hoarded the money.

These are hypothetical questions for bitcoin – no stock market in the world lets you buy equity with the currency yet – but they're very real problems in Japan. The dearth of investment is so bad that the government has "nationalised" industrial stock, spending up to ¥1trn to buy plants in its biggest manufacturing industries.

There is optimism that Japan can pull itself out of this hole. Even as inflation continues to fall, predictions for future inflation are high; and there's a certain sense that with enough wild plans thrown at the wall, something is going to stick. Even if its just out of the frying pan and into the fire, a change of scenario would be nice.

The future's not so rosy for bitcoin. Even if its price stabilises, the long-term policy of deflation is not going to go away. The fact that Japan's "lost decade" lasted fifteen years may seem like a stretch, but bitcoin's could last a lifetime.

Chuka Umunna calls for "solidarity" among Labour MPs, whoever is voted leader

The full text of shadow business secretary Chuka Umunna's speech to Policy Network on election-winning ideas for Labour's future, and the weaknesses of the New Labour project.

There has never been an easy time to be a social democrat (or “democratic socialist” as we sometimes call ourselves in Britain). Whereas the right can demonise the poor and extol the virtues of the market, and the hard left can demonise the market and extol the role of the state, our position of constraining the domination of markets and reforming the state is, by definition, more complex.

It is nonetheless the case that social democracy has a historic responsibility, in every generation, to renew democracy and preserve a civic culture. This is achieved not through soundbites and slogans, but through the hard-headed development of a progressive politics that reconciles liberty and democracy, new comers and locals to our communities, business and workers, in a common life that preserves security, prosperity and peace.  This historic mission is all the more urgent now and my determination that we succeed has grown not weakened since our election defeat last May.

But, in order to be heard, it is necessary to make balanced and reasonable argument that both animates and inspires our movement, and which is popular and plausible with the people.  The first is pre-requisite to the second; and there is no choice to be made between your party’s fundamental principles and electability. They are mutually dependent - you cannot do one without the other.

We are in the midst of choosing a new leader and it is clear to anyone who has watched the UK Labour Party leadership election this summer that amongst a significant number there is a profound rage against Third Way politics – as pursued by the likes of Bill Clinton, Tony Blair, Gerhard Schröder and others - as a rejection of our fundamental values.

In the UK there is a view that New Labour accepted an uncritical accommodation with global capital that widened inequality, weakened organised labour and we were too close to the US Republicans and too far from the European left.

I do not believe this is fair, not least because we rescued many of our public services from the scrap heap when we came to office in 1997 and there were very significant achievements  we should celebrate.  New Labour renewed our National Health Service in a fundamental way; we built new schools and improved existing ones; we set up new children’s centres all over the country; we brought in a National Minimum Wage; we worked with others to bring peace to Northern Ireland; we introduced civil partnerships.  Just some of our achievements.

However, though we may take issue with the critique, I do not think we can simply dismiss out of hand those who hold critical views of New Labour. Like any government, the New Labour administration made mistakes - it could and should have achieved more, and done more to challenge the Right’s assumptions about the world. In the end, it is not unreasonable to be ambitious for what your party in government can achieve in building greater equality, liberty, democracy and sustainability. It is far better we acknowledge, not reject, this ambition for a better world, as we seek to forge a new politics of the common good fit for the future.

Realising our values in office has been disrupted by globalisation and the surge of technological forces that are displacing and reshaping industry after industry.

Some argue that globalisation as an ideological construct of the right. But we must recognise that we live in an increasingly integrated world in which markets have led to an unprecedented participation of excluded people in prosperity, a rise in living standards for hundreds of millions  of people and a literacy unprecedented in human history – this is particularly so in emerging economies like my father’s native Nigeria. And the internet has led to a level of accountability that has disturbed elites.

Yet, this has been combined with a concentration of ownership that needs to be challenged, of a subordination of politics that requires creative rather than reactive thinking, and these global forces have exacerbated inequalities as well as helped reduce poverty.

So it is important that we understand the sheer scale and impact of new technologies. At the moment we are engaged in a debate about Uber and its threat to one of the last vestiges of vocational labour markets left in London, those of the black taxi cabs and their attainment of 'The Knowledge'. But the reality is that within the next decade there will be the emergence of driverless cars so we have to intensify our exploration of how to support people in a knowledge economy and the realities of lifelong learning, as well as lifelong teaching. As people live longer we will have to think about how to engage them constructively in work and teaching in new ways.

Once again, I'm addressing all of this, Social Democracy requires a balanced view that domesticates the destructive energy of capital while recognising its creative energy, that recognises the need for new skills rather than simply the protection of old ones. A Social Democracy that recognises that internationalism requires co-operation between states and not a zero sum game that protectionism would encourage.

Above all, Social Democratic politics must recognise the importance of place, of the resources to be found in the local through which the pressures of globalisation can be mediated and shaped. Our job is to shape the future and neither to accept it as a passive fate nor to indulge the fantasy that we can dominate it but to work with the grain of change in order to renew our tradition, recognising the creativity of the workforce, the benefits of democracy and the importance of building a common life.  Sources of value are to be found in local traditions and institutions.

This also requires a recognition that though demonstration and protest are important,; but relationships and conversations are a far more effective way of building a movement for political change.

One of the huge weaknesses of New Labour was in its reliance on mobilisation from the centre rather than organising. It therefore allowed itself to be characterised as an elite project with wide popular support but it did not build a base for its support within the party across the country, and it did not develop leaders from the communities it represented. It was strong on policy but weak on strengthening democratic politics, particularly Labour politics.

Over half a million people are now members, supporters or affiliated supporters of our party, with hundreds of thousands joining in the last few weeks. Some have joined in order to thwart the pursuit of Labour values but many more have joined to further the pursuit of those values, including lots of young people. At a time when so many are walking away from centre left parties across the Western world and many young people do not vote let alone join a party, this is surely something to celebrate.

So it is vital that we now embrace our new joiners and harness the energy they can bring to renewing Labour’s connection with the people. First, we must help as many them as possible to become doorstep activists for our politics. Second, I have long argued UK Labour should campaign and organise not only to win elections but to affect tangible change through local community campaigns. We brought Arnie Graf, the Chicago community organiser who mentored President Obama in his early years, over from the U.S. to help teach us how to community organise more effectively. We should bring Arnie back over to finish the job and help empower our new joiners to be the change they want to see in every community – we need to build on the links they have with local groups and organisations.

I mentioned at the beginning that in every generation Social Democracy is besieged from left and right but the achievements of each generation are defined by the strength of a complex political tradition that strengthens solidarity through protecting democracy and liberty, a role for the state and the market and seeks to shape the future through an inclusive politics. Solidarity is key which is why we must accept the result of our contest when it comes and support our new leader in developing an agenda that can return Labour to office.

Yes, these are troubled times for social democrats. All over Europe there is a sense among our traditional voters that we are remote and do not share their concerns or represent their interests or values.  There is surge of support for populist right wing parties from Denmark to France, of more left wing parties in Greece and Spain and in Britain too. There is renewal of imperial politics in Russia, the murderous and abhorrent regime of ISIL in the Middle East, volatility in the Chinese economy and in Europe a flow of immigration that causes fear and anxiety.

But, the task of Social Democracy in our time is to fashion a politics of hope that can bring together divided populations around justice, peace and prosperity so that we can govern ourselves democratically. We have seen worse than this and weathered the storm. I am looking forward, with great optimism to be being part of a generation that renews our relevance and popularity in the years to come.
