但对于解决方案各方的观点则没有那么统一。美国经济学家、前美国财政部长萨默斯(Lawarence Summers)和诺贝尔奖获得者、专栏作家克鲁格曼(Paul Krugman)主张政府增加基础设施建设开支。美国国会共和党议员们则坚持认为在当下以及今后减少政府借款会刺激企业招聘和投资。
美国联邦储备委员会(Federal Reserve, 简称：美联储)主席贝南克(Ben Bernanke)及其指定继任者耶伦(Janet Yellen)都一再谈到了这一问题，不过没有向外大声呼吁。实际上，他们都明确地使用了货币政策来弥补短视的财政政策，削减今年的开支成了财政政策的重点。欧洲央行(European Central Bank)行长德拉吉(Mario Draghi)则更加着重强调这一问题，呼吁欧元区领导人不要太过注重短期的危机管理，而应更加关注建立一个更稳定、增长更快、就业更多的经济。
三，大的经济体应当协调实施旨在实现全球经济更好、更加平衡增长的、明智的政策，这一过程或可藉助国际货币基金组织(Internation Monetary Fund)的帮助来实现。比如，有些国家在被告知要紧缩国内开支并加大出口的同时，也需要确信其他国家会扩大进口。作为债务免除的条件，债务国需要让债权国相信一旦压力解除，他们会履行自己所作的改革承诺。
The world economy needs a new strategy to generate faster growth. The recovery from the severe recession continues to disappoint. Each discouraging bit of economic data adds to anxiety that we're going to be stuck with lousy growth for a long time.
There is now growing realization that what the world has been through is not the usual post-World War II recession and recovery. It's worse. It's different. It's chronic. And it will be very hard for any one economy to put the world economy on a better trajectory without help from the others.
There is less agreement on the solution. American economists Lawrence Summers, a former Treasury secretary, and Paul Krugman, a Nobel laureate and columnist, prescribe much more government spending on infrastructure. Congressional Republicans argue that reducing government borrowing, now and in the future, will prompt business to hire and invest.
The Germans are trying to compensate for frugal consumers and businesses at home by exporting more, and prescribing austerity and deregulation for Southern Europe. The British are trying belt-tightening, easy money and a depreciation of the pound to boost exports.
The Japanese are printing lots of money and pushing down the yen while Shinzo Abe's government tries to sort out conflicting fiscalpolicy impulses--to raise consumption taxes to bring down debt or increase spending to bolster growth--and are moving slowly to deregulate. The Chinese, meanwhile, vow to rely more on consumer spending and less on exports and unneeded infrastructure investment, but are vague about how and when.
To a substantial degree, major economies and their elected leaders are relying too much on their central banks and too much on exports.
In the U.S., Japan, the U.K. and the euro zone, central banks have kept their economies growing with a mix of very low interest rates, calming words and printing a lot of money to buy bonds. These efforts, while the subject of lively debate, were and continue to be a good way to avoid a repeat of the Great Depression.
But monetarypolicy by itself cannot solve chronic growth problems.
Both Fed Chairman Ben Bernanke and his designated successor Janet Yellen have said as much, though they haven't shouted it. Indeed, they're explicitly using monetarypolicy to compensate for short-sighted fiscalpolicy that is preoccupied with cutting this year's spending. The European Central Bank's chief, Mario Draghi , has been more emphatic, telling leaders in the euro zone 'to be less absorbed in short-term crisis management, and more focused on building an economy with more stability, more growth and more jobs.'
For any one country, particularly one that is burdened with a lot of debt, it makes sense to tighten public and private domestic belts, welcome a falling currency and look to exports.
But not everyone can do this at the same time; someone has to be the importer. Countries with big trade surpluses--Germany and China--need to buy more from debtor countries so they can reduce some of that burden. This, of course, is a hard to sell to German and Chinese politicians understandably reluctant to endanger all those export-related jobs.
Add this all up: Monetary policy that is struggling to pedal up hill, misguided fiscal policy, too much focus on avoiding short-term slumps and not enough on nurturing long-term growth, more talk about 'reform' than action, too many countries counting on foreign demand to offset weak domestic demand. No wonder the world economy is growing so slowly.
I asked a veteran of global economic policy making this week how the world economy can get to a better place? He had three suggestions:
One, global economic policy makers need to recognize this is no ordinary business cycle. Governments can and should offset weak private-sector demand with spending and tax cuts, but they need to realize that's not enough. They need to stop dithering and do things that could bolster consumer and business confidence so they'll spend and invest more readily--dealing with long-term budget deficits and failing schools in the U.S., getting on with the creation of a banking union in Europe, shooting the third arrow of Abenomics--deregulation and the like--in Japan.
Two, the Doha round of world trade talks among developed and developing economies should be put out of its misery. Instead, he suggested, developed countries should pursue U.S.-Europe, U.S.-Asia and Europe-Asia pacts to lower barriers to trade, to give their own businesses more reason to invest and to jolt emerging markets into compromises.
Three, perhaps helped by the International Monetary Fund, big economies need to give each confidence that each will pursue wise policies in parallel aimed at better and more balanced global growth. Those told to tightendomestic belts and export more, for instance, need to know that others will buy more. In exchange for debt relief, borrowers need to convince creditors that they'll keep their reform promises once the pressure is off.
None of those are easy; they might not even be the best options. But the status quo risks a decade of stagnation.
