美国不会日本化

美国不会日本化

日本的中央银行制度、人口结构、选举制度以及经常顺差是造成其长期通货紧缩的深层次原因。这些因素在美国没有发挥作用的基础
王庆/文

在全球金融危机之后,美国债台高筑。大规模的财政赤字将会成为长期现象,同时通货紧缩的阴影挥之不去,这一切不禁使人们担心:美国是否会成为下一个日本,是否将有一个甚至几个“失去的十年”。

的确,从初始条件看,美国经济现在的状况很像当年的日本。在上世纪80年代的日本,不动产市场泡沫破裂,导致经济严重衰退。在当前的美国,居民房地产和信用泡沫的破裂,不仅已经导致经济的衰退,而且随时有通货紧缩的风险。

很多分析人士把日本长达20年的通货紧缩归咎于其货币政策的失败。遵循同样的逻辑,只要美联储不重复日本央行的错误,美国就不会“日本化”。

笔者认为,这样的分析只是触及了表面现象。而核心问题是,为什么通货紧缩在日本持续的时间如此之长?为什么日本社会主动或被动地,有意识或无意识地选择了长期通货紧缩?在后金融危机时代,美国社会是否做出同样的选择?

日本长期通缩源于四个深层的结构和制度性因素。

首先是日本的中央银行制度。自1998年以来,日本央行享有极高的独立性,但却没有与其权利相匹配的问责制度。尽管《日本中央银行法》给日本央行的任务定位是“通过价格稳定来帮助国民经济的健康发展”,但实际上,日本央行直至2006年才给出了一个“价格稳定”的定义,也就是在0%至2%之间。然而, 在此后的51个月内,日本的核心通胀率有46个月低于0%,出现了严重通缩,但日本央行并未因此被问责。

为什么日本社会的问责要求如此之低呢?这就涉及到第二和第三个深层因素:日本的人口结构和选举制度。

在过去的20年里,日本人口迅速地老龄化,退休人口比重越来越高。一个老龄化的社会更倾向选择通货紧缩。退休人员的主要收入来源是退休金和其他固定收益类投资产品,鲜有股票类投资品。尽管在通缩环境下,名义利息率很低,但价格下降会提高退休人员的实际收入水平,可以很大程度上抵消利息收入的不足。

日本政治选举制度的设计客观上赋予年长的人群超比例的影响力,从而使政策的制定越来越倾向于保护年长者的利益。作为利益共同体,他们会反对通胀,更倾向采取导致通缩的政策措施。

第四个深层次的因素与日本长期经常账户顺差有关。经常账户顺差的存在,意味着经济整体是净储蓄。这一宏观环境下,财政赤字很容易通过国内发债融资来支持,从而客观上减弱了采取结构改革政策的动力。没有强有力的制度变革,就无法消除由大规模不良资产引致的通缩压力。

上述四个因素在美国发生作用的可能性不大,因此,美国不会日本化。

首先,美联储虽然享有高度的独立性,但在其政策目标中,不仅有通胀还包括就业。

尽管美联储在制度上没有明确规定的通胀目标值,但长期以来,政策制定者和市场参与者已经达成一个共识:美联储的通胀目标值是2%。同时,美国国会对美联储有明确的问责制度。具体体现在,国会参众两院对美联储主席任命的影响,以及频繁地举行关于货币政策的听证会。

其次,尽管美国人口老龄化也在进行,但在相对开放的移民政策等因素的作用下,美国老龄化程度和速度都远未达到日本的状况。

第三,美国的政治选举制度并不存在有利于年长人群的安排。公共政策能够均衡地反映各年龄阶层的诉求,没有采取通缩政策倾向的偏好。

第四,与日本不同,美国有长期经常账户逆差,意味着整个经济体是负储蓄,需要从其他国家借入资金。这样,市场的约束力量就会迫使当局采取有效的结构改革政策,促进经济增长预防通缩,并减少财政赤字,否则,其融资成本会大幅上升。

实际上,相比美国,欧洲经济更容易像日本那样陷入长期通缩。因为,在上述四个方面,欧洲的状况介于美国和日本之间。

尽管有非常明确的通胀目标,欧洲央行并不对某一个主权政府负责。欧洲的人口结构和发展趋势介于美国和日本之间。同时,没有迹象表明,当前欧洲的选举制度含有利于年长者的倾向。尽管不同欧元区国家的经常状况有很大差别,有些有大量的顺差(如德国),另一些国家有大量逆差(如希腊),但从欧元区整体看,经常账户基本平衡。■

America needs a growth strategy *

Underinvestment in
infrastructure
manufacuturing/tradable sector

By Michael Spence

As the International Monetary Fund warned on Thursday, America’s economy shows worrying signs of weakness. Worse, and in common with other developed countries, it also lacks a credible strategy for longer-term growth. Without such a strategy, a strong global recovery is unlikely.

The structural evolution of the US economy over the past 15 years has been driven by excess consumption, enabled by debt-fuelled asset inflation. The crisis put a stop to this, but structural deficiencies remain. America’s export sector is too small and underdeveloped. The financial sector became outsized, and is down-sizing.

A pattern of underinvestment in infrastructure has left the economy less competitive than it should be. Energy pricing issues have been ignored, causing underinvestment in urban infrastructure and transport. The education system has widespread problems with efficiency and effectiveness. Elsewhere, state budgets are in distress as a result of insufficiently conservative budget policies.

Even with a fiscal strategy that balances short-term stimulus and longer- term stability, America must still address the composition and size of expenditures, investments and revenues. To finance growth-supporting long-term investments, domestic private consumption has to shrink. This means higher taxes. In addition, existing government expenditure must be shifted away from consumption and towards investment, meaning fewer government services. Restoring fiscal balance in a way that supports longer-term growth will therefore be painful.

But even that is not enough. The real issue is employment: not just stubbornly high unemployment, but a bigger problem described recently in a thoughtful article by Andy Grove, the long-time chief executive of Intel. He argued that manufacturing is vanishing in the US, a trend that must be reversed. The question is how.

There is little doubt that America’s social contract is starting to break. It had on one side an open, flexible economy, and on the other the promise of employment and rising incomes for the motivated and diligent. It is the second part that is unravelling.

Incomes in the middle-income range for most Americans have stagnated for more than 20 years. Manufacturing jobs are moving offshore. Globally the set of goods and services that is tradable is expanding, but the US and other advanced countries are not competing successfully for an adequate share of the tradable sector.

The employment effects of these trends over the past 15 years have been masked by excess consumption and the overdevelopment of sectors such as finance and real estate. The latter are now set to shrink, as multinational companies grow where they have access to high-growth emerging markets in Asia and Latin America. Such companies will locate their operations where market and supply chain opportunities lie. In the tradable sector, in manufacturing and in a growing group of services, that means outside advanced countries.

The availability of low-cost, disciplined labour forces in developing countries reduces the incentive for these companies to invest in technologies that enhance labour productivity in the tradable sectors of the advanced economies. As a result, the evolving composition of advanced economies is increasingly weighted towards the non-tradable sector, combined with a set of high-end tradable services where both human capital and proximity matter. The rest of the tradable sector is shrinking.

The shrinkage creates problems. Over-specialisation could threaten independence and national security. Spillovers between R&D, product development and manufacturing will be lost if manufacturers leave. Employment will stagnate. Income distribution will move adversely and the social contract will erode further.

Solutions to these problems are not easy to find. The unequal distribution of income can be dealt with through the tax system, although this does not attack the underlying problem. Protectionism could alter the pattern of out-migration of manufacturing, but only by imposing costs on domestic consumers and risking the breakdown of the open global economy model.

To avoid an outbreak of protectionism, there has to be an alternative. President Barack Obama’s new export council, announced on Wednesday, is a step in the right direction. But a bolder move is needed: a broad public-private partnership to invest in the development of technology in parts of the tradable sector where there are opportunities to make advanced countries competitive. The goal must be to create capital-intensive jobs that have labour productivity levels consistent with advanced country incomes.

Would this damage developing countries? Clearly not. The US (or even developed economies combined) does not have hundreds of millions to employ. A targeted programme would leave the vast majority of labour-intensive manufacturing right where it is now: in the developing world. With new credible growth strategies in America (and other advanced countries) developing countries may even be willing to play an important complementary role in restoring global demand through, for example, the reduction of excess savings.

We are already on a lengthy and bumpy road to a new normal. That is unavoidable. The risk is that without a new direction in American economic policy, the new normal may be as unpleasant as the journey.

Tomorrow's burden

--Inflation is not a concern because both economic growth and labor market are weak --No other currency will replace dollar in the near future a.SDR is limited to government use b.Euro is new c.China currency is not convertible and China legal system is not internationally friendly --ex Oct 22nd 2009 WASHINGTON, DC From The Economist print edition America’s debt crisis will be chronic, not acute Illustration by Belle Mellor AS AMERICA’S financial crisis recedes, the rumblings of its next crisis can be heard. The federal government has wrapped its guarantees around banks and the housing market. It has borrowed hundreds of billions of dollars to stimulate the enfeebled economy, while tax revenues crumble. And in the years to come the cost of retirees’ benefits will explode. “There is every reason to worry that the banking crisis has simply morphed into a long-term government-debt crisis,” says Kenneth Rogoff of Harvard University. But what kind would it be: acute or chronic? If it were an emerging market, America would probably have hit trouble already: foreigners would have recoiled from financing its gaping budget deficits; default or a bail-out would have followed. The past two years have shown that rich countries are not immune to acute crises. Iceland’s case has been the most severe: the IMF had to save the country from collapse. Others have displayed milder symptoms: credit markets have discounted meaningful odds that Greece, Ireland or Italy would default. But although an acute crisis cannot be ruled out, America’s is far more likely to be chronic. Its expansion is likely to be sluggish and deflationary, which make it economically and politically hard to reduce debt. Of course, America could still give investors a scare. Within two months the Treasury will probably have reached the statutory limit on the amount of debt it can issue. In a peculiarly American ritual, Congress often grandstands before agreeing to raise it. In 1996 its Republican leaders unsettled markets by pooh-poohing the consequences of default before eventually granting Bill Clinton’s request. The Treasury’s ravenous borrowing needs also leave lots of opportunities for something to go wrong. In the past two years the portion of its debt maturing in less than a year has jumped from 30% to over 40%, the most since the early 1980s (see chart 1). In the fiscal year that ended on September 30th the Treasury held an auction on average more than once a day to finance nearly $7 trillion of new and maturing debt. A failure to raise as much money at an auction as planned—as occurred in Britain earlier this year—could send a shudder through global financial markets. “Other countries can afford a failed auction; we can’t,” says Lou Crandall, chief economist at Wrightson ICAP, a financial-research firm. “What do you do when there is a confidence shock to your flight-to-safety asset?” But it is difficult to identify any such concerns today. If anything, the underlying demand for Treasury bonds is rising. Mr Crandall notes that in the past year the share of Treasury debt bought at auctions by big investors and foreign central banks (as opposed to dealers) has roughly doubled to around 60%. Yields on ten-year Treasuries, at 3.3%, are lower than they were in August 2008, before bail-outs and recession sent projected deficits into the stratosphere. It may be that other, temporary forces, such as the lack of private borrowing or the Fed’s easy monetary policy, are offsetting any worries about deficits. Yet Tom Gallagher, an analyst at ISI Group, a broker-dealer, estimates that investors’ expectations of yields in five years’ time, when such temporary factors will have faded, are no higher than they were last summer. The reason, he says, is not that bond investors do not care about deficits, but that they assume—perhaps wrongly—that politicians simply will not allow those deficits to materialise. America may be the world’s strongest borrower, thanks to its size, wealth, legal and political stability, and two centuries of timely debt repayment (the one exception being its abrogation in 1933 of a promise to repay some bondholders in gold). Such demonstrated willingness to pay means a lot to lenders, because they cannot push countries into bankruptcy court. America also borrows in the currency other countries most want to hold in their own foreign-exchange reserves. In May Standard & Poor’s said Britain could lose its AAA rating. America has been spared the same fate in part, S&P says, because of the “unique external flexibility” granted by the dollar’s reserve currency status. Recently China and other countries have questioned that status, advocating greater use of other currencies or a currency basket like the IMF’s Special Drawing Right (SDR). Yet the dollar’s share of global foreign-exchange reserves has remained high. It fell to 63% in mid-2009 from 72% in 2001 because of the decline in its value, not reduced demand. The share was 59% in 1995. The data show central banks buy more dollars when it falls and less when it rises, says Stephen Jen of BlueGold Capital, a hedge fund. The view of Kazakhstan’s central-bank governor, Grigory Marchenko, is typical. His country will eventually reduce the dollar’s share of its reserves, he said last month, but not for a long time: “There’s no alternative yet.” SDRs’ potential is limited by the fact that only governments use them. The euro is still young and the euro zone’s borders are not yet fixed. China’s economy may one day rival America’s. But Dino Kos, a former chief of markets at the Federal Reserve Bank of New York who now works for Portales Partners, a research firm, notes that the yuan does not meet one of the most basic requirements of a reserve currency: other countries cannot use it to intervene in foreign-exchange markets because it is not freely convertible. Moreover, central banks loathe uncertainty; the arrest of four Rio Tinto employees this year on charges of stealing state secrets (downgraded to obtaining commercial secrets) shows that China’s legal system remains capricious. Eventually, the dollar’s dominance will fade; but as with sterling in the last century, this will take decades. Of course, American policies could hurry it up, in particular by trying to reduce the debt burden through inflation. In March the Federal Reserve began buying $300 billion in Treasury bonds to push down long-term interest rates. Such purchases amount to printing money, and aroused fears that the Fed was subordinating inflation-control to helping the government finance its deficits. “I must have been asked about that a hundred times in China,” Richard Fisher, president of the Federal Reserve Bank of Dallas, told the Wall Street Journal in May. But inflation is harder to create than you think. It would require the economy to grow so rapidly that unemployment plummeted and businesses returned to full capacity. Even the most optimistic forecasts say that is years away. Inflation could rise more quickly if the public came to expect higher inflation. But Donald Kohn, vice-chairman of the Fed, recently predicted that both inflation and inflation expectations were more likely to drop than to rise. Trouble in slow motion In short, the likeliest triggers of an acute crisis—a lenders’ strike, a crash in the dollar or inflation—seem remote. Not so the damage of a chronic, slow-motion crisis. Publicly held debt, just 37% of GDP two years ago, has already jumped to 56%. How much further it rises depends crucially on how fast the economy grows: higher growth leads to narrower deficits and a larger GDP to support the debt. The White House sees deficits stuck at around 4% of GDP and the debt ratio reaching 77% by 2019. The IMF, which forecasts lower growth, sees the deficit rising to around 7% of GDP and the debt ratio to 100%. The Congressional Budget Office (CBO) is in between (see chart 2). Debts of that magnitude elevate interest rates, crowd out private investment and damp growth. In 2004 William Gale of the Brookings Institution and Peter Orszag, now Barack Obama’s budget director, estimated that an increase of 1% of GDP in future deficits would raise long-term interest rates by 0.4-0.7 percentage points. They reckoned that continuing deficits of 3.5% of GDP would reduce national income by 1-2%. Rising debts also force the government to divert tax revenue from public services to interest payments. The CBO estimates that by 2019 interest on the national debt will consume 3.8% of GDP, more than twice its share earlier this decade. Bigger deficits raise interest rates not just by competing for savings, but by raising doubts about America’s ability to repay the money. Moody’s Investors Service notes that, including what states owe, America’s government debt will hit 100% of GDP in 2010, higher than other AAA-rated nations (see chart 3). “If it looks like, after the crisis is over, the trajectory of the debt is going to be continuously upward, I’d say the rating could be in jeopardy,” says Steven Hess, an analyst at Moody’s. Canada lost its AAA credit rating in the early 1990s as its combined federal and provincial debt ratio neared 100%. (It won it back in 2002.) Japan was marked down in 1998 when its ratio hit 115%. Ireland lost its AAA grade this year when the banking crisis exposed the government to huge risk. Mr Hess remarks that banking crises often trigger downgrades, as in Ireland earlier this year and Sweden in the early 1990s, because the government ends up backing a lot of private-sector liabilities. America has implicitly backed the biggest banks and much of the residential-mortgage market. The extra exposure, Mr Hess notes, is far smaller than Ireland’s. Still, if growth proves weak, the public will be on the hook for more bad private debts. A rating downgrade would not be cataclysmic; AA-rated countries borrow without problems. But interest rates would rise for the Treasury as well as anyone else who borrows in dollars, including corporations and state governments. Higher interest payments would mean further pressure on the deficit and debt. Stabilising debt as a share of GDP requires some combination of faster economic growth, higher taxes, or lower spending. It can be done. The ratio topped 100% during the second world war. It later fell rapidly as defence spending shrank, the economy bounded forward and policymakers made some difficult choices: Harry Truman paid for the Korean war with higher taxes. In recent decades several heavily indebted rich countries have clawed their way back to health without resort to default or inflation, notably Canada, Denmark and Sweden. These episodes provide little comfort to America now. Its defence budget is too small, as a proportion of GDP, to make a meaningful contribution to deficit reduction. Both Canada and Sweden started with large public sectors and shrank them; Mr Rogoff notes that America’s public sector is expanding. More important, devalued currencies and strong exports boosted growth while they wrestled down their deficits. In contrast, American exports are much smaller relative to GDP and the rest of the world remains sickly. Falling interest rates provided a tailwind to deficit reduction in all countries through the 1980s and 1990s as inflation phobias accumulated over prior decades seeped away. America is more likely to experience the opposite since its interest rates are already so low. Japan’s example may be more relevant. Beginning in the early 1990s, a prolonged banking crisis, sluggish growth, deflation and numerous stimulus plans drove its debt ratio up dramatically; it is still rising. Its interest rates remain low, largely because Japan borrows almost entirely from its own citizens whereas half of America’s debt is owed to foreigners. Japan tried to corral its debt by raising taxes in 1997; it promptly snuffed out a recovery. Japan’s experience illustrates the excruciating dilemma facing American policymakers. The White House acknowledges the deficits it projects are too high. But slashing spending or raising taxes too soon could snuff out recovery and leave America with even bigger deficits. Asked on October 15th when the administration would tackle the deficit, Tim Geithner, the treasury secretary, said: “First, growth.”
