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.

The Future of the Left: A new start requires a new economy

Creating a "sharing economy" can get the left out of its post-crunch malaise, says Stewart Lansley.

Despite the opportunity created by the 2008 crisis, British social democracy is today largely directionless. Post-2010 governments have filled this political void by imposing policies – from austerity to a shrinking state - that have been as economically damaging as they have been socially divisive.

Excessive freedom for markets has brought a society ever more divided between super-affluence and impoverishment, but also an increasingly fragile economy, and too often, as in housing, complete dysfunction.   Productivity is stagnating, undermined by a model of capitalism that can make big money for its owners and managers without the wealth creation essential for future economic health. The lessons of the meltdown have too often been ignored, with the balance of power – economic and political – even more entrenched in favour of a small, unaccountable and self-serving financial elite.

In response, the left should be building an alliance for a new political economy, with new goals and instruments that provide an alternative to austerity, that tackle the root causes of ever-growing inequality and poverty and strengthen a weakening productive base. Central to this strategy should be the idea of a “sharing economy”, one that disperses capital ownership, power and wealth, and ensures that the fruits of growth are more equally divided. This is not just a matter of fairness, it is an economic imperative. The evidence is clear: allowing the fruits of growth to be colonised by the few has weakened growth and made the economy much more prone to crisis.

To deliver a new sharing political economy, major shifts in direction are needed. First, with measures that tackle, directly, the over-dominance of private capital. This could best be achieved by the creation of one or more social wealth funds, collectively held financial funds, created from the pooling of existing resources and fully owned by the public. Such funds are a potentially powerful new tool in the progressive policy armoury and would ensure that a higher proportion of the national wealth is held in common and used for public benefit and not for the interests of the few.

Britain’s first social wealth fund should be created by pooling all publicly owned assets,  including land and property , estimated to be worth some £1.2 trillion, into a single ring-fenced fund to form a giant pool of commonly held wealth. This move - offering a compromise between nationalisation and privatization - would bring an end to today’s politically expedient sell-off of public assets, preserve what remains of the family silver and ensure that the revenue from the better management of such assets is used to boost essential economic and social investment.

A new book, A Sharing Economy, shows how such funds could reduce inequality, tackle austerity and, by strengthening the public asset base, rebalance the public finances.

Secondly, we need a new fail safe system of social security with a guaranteed income floor in an age of deepening economic and job insecurity. A universal basic income, a guaranteed weekly, unconditional income for all as a right of citizenship, would replace much of the existing and increasingly means-tested, punitive and authoritarian model of income support. . By restoring universality as a core principle, such a scheme would offer much greater security in what is set to become an increasingly fragile labour market. A basic income, buttressed by a social wealth fund, would be key instruments for ensuring that the potential productivity gains from the gathering automation revolution, with machines displacing jobs, are shared by all.  

Thirdly, a new political economy needs a radical shift in wider economic management. The mix of monetary expansion and fiscal contraction has proved a blunderbuss strategy that has missed its target while benefitting the rich and affluent at the expense of the poor. By failing to tackle the central problem  – a gaping deficit of demand (one inflamed by the long wage squeeze and sliding investment)  - the strategy has slowed recovery.  The mass printing of money (quantitative easing) may have helped prevent a second great depression, but has also  created new and unsustainable asset bubbles, while austerity has added to the drag on the economy. Meanwhile, record low interest rates have failed to boost private investment and productivity, but by hiking house prices, have handed a great bonanza to home owners at the expense of renters.

Building economic resilience will require a more central role for the state in boosting and steering investment programmes, in part through the creation of a state investment bank (which could be partially financed from the proposed new social wealth fund) aimed at steering more resources into the wealth creating activities private capital has failed to fund.

With too much private credit used for financial speculation and property, and too little to small companies and infrastructure, government needs to play a much more direct role in creating credit, while restricting the almost total freedom currently handed to private banks.  Tackling the next downturn, widely predicted to land within the next 2-3 years, will need a very different approach, including a more active fiscal policy. To ensure a speedier recovery from recessions, future rounds of quantitative easing should, within clear constraints, boost the economy directly by financing public investment programmes and cash handouts (‘helicopter money’).  Such a police mix – on investment, credit and stimulus - would be more effective in boosting the real economic base, and would be much less pro-rich and anti-poor in its consequences.

These core changes would greatly reform the existing Anglo-Saxon model of capitalism and provide the foundations for building support for a new direction for progressive politics. They would pioneer new tools for building a fairer, more dynamic and more stable economy. They could draw on experience elsewhere such as the Alaskan annual citizen’s dividend (financed by a sovereign wealth fund) and the pilot basic income schemes launching in the Netherlands, Finland and France.  Even mainstream economists, including Adair Turner, former chairman of the Financial Services Authority, are now talking up the principle of ‘helicopter money’. For these reasons, parts of the package are likely to prove publicly popular and command support across the political divide. Together they would contribute to a more stable economy, less inequality, and a more even balance of power and opportunity.
