Moreover, the shift in the private sector balance between 2007 and 2010 is forecast to be 9.7% in USA, and exceed 10%/GDP in no fewer than 8 OECD member countries. It is also forecast to exceed 5%/GDP in another 8.

Wolf then asks, "So how do we exit? To answer the question, we need to agree on how we entered. A big part of the answer is that a series of bubbles helped keep the world economy driving forward over the past three decades. Behind these, however, lay a credit super-bubble, which burst in 2008. This is why private spending imploded and fiscal deficits exploded."
I explain what he means by the bubbles in terms of credit boom growth later below.
Wolf continues, "Now, after the implosion, we witness the extraordinary rescue efforts. So what happens next? We can identify two alternatives: success and failure.
By “success”, I mean reignition of the credit engine in high-income deficit countries. So private sector spending surges anew, fiscal deficits shrink and the economy appears to being going back to normal, at last. By “failure” I mean that the deleveraging continues, private spending fails to pick up with any real vigour and fiscal deficits remain far bigger, for far longer, than almost anybody now dares to imagine. This would be post-bubble Japan on a far wider scale. Unhappily, the result of what I call success would probably be a still bigger financial crisis in future, while the results of what I call failure would be that the fiscal rope would run out, even though reaching the end might take longer than worrywarts fear. Yet the big point is that either outcome ultimately leads us to a sovereign debt crisis. This, in turn, would surely result in defaults, probably via inflation. In essence, stretched balance sheets threaten mass private sector bankruptcy and a depression, or sovereign bankruptcy and inflation, or some combination of the two. I can envisage two ways by which the world might grow out of its debt overhangs without such a collapse: a surge in private and public investment in the deficit countries or a surge in demand from the emerging countries. Under the former, higher future income would make today’s borrowing sustainable. Under the latter, the savings generated by the deleveraging private sectors of deficit countries would flow naturally into increased investment in emerging countries."
Martin Wolf recognised and repeats here what Lord Turner at the FSA and others, but not all, know that the credit crunch has its origins in extreme world trade imbalances that developed in the past decade, extreme differences between credit boom (CB) growth economies (that he calls deficit countries) and export-led (EL) growth economies (that he calls high-income countries).
In CB economies (USA above all, also UK, Spain, Ireland, Greece etc.) increasingly the trade deficit was financed by banks selling asset backed securities directly and indirectly to the EL economies (Germany, Japan, China etc.). The CBs grew by boosting domestic consumption and housing wealth thereby drawing in more and more net imports, while the ELs grew by exports and by capital investment (especially in China's case).
The world, and within it the EU, was polarised by two growth policy extremes, between CBs with a rampant internal growth impulse and ELs profiting from CBs by remaining heavily baised to external growth impulse; everyone else can be placed in a mixed continuum somewhere in between.
Martin points to the dilemma we face now. This reduces to how to avoid simply returning everything to how it previously was? He suggests we do this by CBs investing more and ELs consuming more. The CBs and ELs have to shift, or even reverse, their stances, essentially to rejoin the rest of the world in a mixed policy of trying to balance external and internal growth.
For die hard monetary policy managers, I'm sorry for them if they find such an explanation with its focus on external account and trade too much like Keynesiansm of the past, unpalatable, deeply unfashionable for their modernist technocratic-monetary taste.

China, in pursuit of its healthy aspirations to lead the BRICS and join the OECD country club, should enforce its 40-hour week legislation and encourage its population to aspire to more leisure and a higher quality of life. But, the same is also true of highly developed EL economies, Germany and Japan. They need to do far more to actively examine their own internal barriers to higher consumption and internal job creation.
The CBs are far less averse to changing their growth stance that the ELs with their classic conservatism of why do anything different when I have plenty of money lying in the bank?
We may have to wait for China to experience an almighty asset bubble burst and then for the German-led Euro Area's regular recession bus to arrive in about 2 year's from now.
What will shake Japan out of its tree should not be yet more loss of self-confidence, but a recognition that it is time to take its profits and spend that domestically to give its hard-working people the reward of a decade or so of a good time. Of course, the USA tried in vain saying that to Japan for decades without response, and no doubt that is the model that inspires China.
Wolf points to further implications, "Yet exploiting such opportunities would involve radical rethinking. In countries like the UK and US, there would be high fiscal deficits over an extended period, but also a matching willingness to promote investment. Meanwhile, high-income countries would have to engage urgently with emerging countries, to discuss reforms to global finance aimed at facilitating a sustained net flow of funds from the former to the latter. Unfortunately, nobody is seized of such a radical post-crisis agenda. Most people hope, instead, that the world will go back to being the way it was. It will not and should not. The essential ingredient of a successful exit is, instead, to use the huge surpluses of the private sector to fund higher investment, both public and private, across the world. China alone needs higher consumption. Let us not repeat past errors. Let us not hope that a credit-fuelled consumption binge will save us. Let us invest in the future, instead."
