????持續(xù)蔓延的歐洲債務(wù)危機大有演變?yōu)槿蚪鹑跒碾y之勢,，雖然各方已通過一系列措施努力防范,，但仍然不能安撫投資者的情緒：希臘、葡萄牙和愛爾蘭都處于崩潰邊緣,，意大利和西班牙可能緊隨其后,。盡管德國和法國經(jīng)濟形勢現(xiàn)在還過得去，但就算是這些健康的經(jīng)濟體,，也出現(xiàn)了疲軟的跡象,。

????上周二，希臘議會投票通過法案,，開征一項非常不得人心的財產(chǎn)稅,。這一舉措是其緊縮計劃的一部分，而后者則這是獲得歐盟援助資金的前提,。此外,，歐盟官員們正在采取措施充實一項基金，以便向麻煩纏身的成員國提供低息貸款,。

????可是,，就算歐洲金融穩(wěn)定基金（the European Financial Stability Facility）的權(quán)限得以擴大，其效率仍然是個未知數(shù),。投資者仍然擔心,，如果西班牙或意大利等規(guī)模更大的經(jīng)濟體突然需要援助，這個成立于去年的基金依然拿不出足夠的資金,。

????政界現(xiàn)階段或許無意尋求更大膽的主意,，但市場對此卻十分期待，因為歐洲債務(wù)危機可能將全世界都拖入新一輪的嚴重衰退。

????正如資產(chǎn)管理公司Gluskin Sheff & Associates的首席經(jīng)濟學家大衛(wèi)?羅森博格在周二希臘議會投票前所寫的備忘錄中所稱：市場希望“有人砸出海量的資金來解決這個問題,，不管誰買單都無所謂（只要不是銀行持有這些債務(wù)就行?。,！?/p>

????其中一種解決方案是,，給希臘一筆規(guī)模大得多的援助資金，條件是一旦該國債務(wù)累累的經(jīng)濟體開始復蘇并實現(xiàn)增長,，作為回報，它必須拿出更多資金償還債務(wù),，哈佛大學經(jīng)濟學教授肯尼斯?羅格夫就支持這個方案,。

????這個方案與他解救美國房地產(chǎn)市場的設(shè)想頗為相似。美國房地產(chǎn)市場目前仍然深陷困境,，許多房主所承擔的抵押貸款甚至超過了房屋的現(xiàn)價,。羅格夫認為，如果房主同意分享住宅未來升值的收益,，銀行可以減記其貸款余額,。同理，如果希臘愿意在未來經(jīng)濟表現(xiàn)好轉(zhuǎn)的時候多加回報,，歐洲的富裕國家也就可能同意給希臘規(guī)模大得多的援助（用羅格夫的話來說,，“大到真的管用”）。

????如此一來,，借款方和援助方都有理由期待這筆交易能夠成功,。或許更重要的是,，雙方都付出了代價,，沒人可以免費搭便車——至少在原則上是這樣。

????就美國房地產(chǎn)市場的例子而言,，這種方案意味著雙贏,。不僅那些所欠貸款超過房屋市價的房主能夠獲利，而且貸款方和投資者最終也能獲得回報,，使其給予借款方喘息之機的舉動同樣有利于自己,。同理，負債累累的歐洲邊緣成員國的債務(wù)壓力將會大幅減輕,。一旦這些經(jīng)濟體重新實現(xiàn)健康成長——比方說在10到15年之后——納稅人必須將國內(nèi)生產(chǎn)總值（GDP）增長額的一定比例償還給富國,。

????除此之外，羅格夫并未作出詳細闡釋,，但幾乎可以肯定地推斷：任何此類計劃都將緩解希臘的緊縮政策——歐洲央行和國際貨幣基金組織迫使希臘推行此類政策,，以交換援助資金。可這些措施給希臘造就了一把雙刃劍,，如果希臘未來不能實現(xiàn)經(jīng)濟增長,，又怎么可能償還貸款？

????沒錯,，讓一個負擔著巨額債務(wù)的國家削減開支是合情合理的,。但事實證明，裁掉數(shù)以千計的政府雇員,，提高稅收,，給希臘經(jīng)濟帶來了災難性的后果。該國國內(nèi)生產(chǎn)總值的萎縮幅度超出所有人的預期,，2010年下降了6%,，截至6月份的三個月中又下降了7.3%。如果增長率繼續(xù)下降,，希臘將無法實現(xiàn)財政收入目標,，甚至會要求更多援助。市場走勢表明,，投資者預期希臘最終將會債務(wù)違約,，很大程度上正是因為擔憂上述惡性循環(huán)。

????據(jù)彭博社（Bloomberg）報道,，希臘國債暴跌,，表明投資者認為違約率超過90%。目前,，希臘兩年期國債的收益率已經(jīng)超過70%,。

????羅格夫的主意實質(zhì)上就是給希臘提供一筆可以延期償還的長期貸款。這個計劃并非沒有缺陷,，很可能招致政界的反對——至少眼下的確如此,。德國顯然已經(jīng)受夠了，不愿再做歐洲的終極貸款人,。盡管為更大規(guī)模的援助計劃提供資金最終可能使德國獲得豐厚回報,，但這仍然很可能被視為富國免費援助窮國，而后者卻不顧自身經(jīng)濟實力,，肆意揮霍資金,。

????況且，密歇根大學福特公共政策學院(University of Michigan's Gerald R. Ford School of Public Policy)副院長艾倫?迪爾多夫指出,，現(xiàn)在的問題不僅是如何讓富國參與進來,，希臘本身也得要有動力才行，否則該國可能也不會同意這個方案,，因為它實際上相當于開征新稅,，將來出現(xiàn)任何形式的收入增長都將被征稅,。事實上，對未來國內(nèi)生產(chǎn)總值增長所征的稅必須控制在一定比例之內(nèi),，否則希臘就會喪失促進經(jīng)濟增長的動力,。而希臘的增長有賴于對本國經(jīng)濟進行深層次的結(jié)構(gòu)性改革。

????雖然羅格夫的想法當前可能無法獲得政治上的支持,，但至少在理性上,，它頗有吸引力，稍晚些時候或許會更值得考慮,。

????After a series of efforts to keep Europe's ongoing debt crisis from turning into a worldwide financial disaster, it seems as though little has calmed investors: Greece, Portugal and Ireland are on the brink. Italy and Spain could be next. And while the economies of Germany and France are doing okay for now, even the healthy ones are showing signs of weakness.

????Late Tuesday, lawmakers in Athens voted on a hugely unpopular property tax as part of a package of cuts to secure funds for a bailout package. Officials are also working to beef up a fund that facilitates low-cost loans for struggling EU countries.

????But even with new powers granted to the European Financial Stability Facility, it's still uncertain how effective it will be. Investors continue to worry that the fund, established last year, won't have enough money if bigger economies such as Spain or Italy suddenly need a lifeline.

????Politicians may not be looking for bold ideas at this point, but the markets certainly are, as Europe's debt crisis threatens to plunge the world into another deep recession.

????As Gluskin Sheff & Associates chief economist David Rosenberg wrote ahead of Tuesday's vote: The markets want "massive amounts of money thrown at the problem, regardless of who pays (so long as it's not the banks holding the debt!)."

????One solution is to give Greece a much bigger bailout in exchange for bigger payments once its heavily indebted economy begins to heal and grow, as Harvard economist Kenneth Rogoff has suggested.

????The idea is analogous to what he thinks could help fix America's troubled housing market. Just as homeowners could receive write-downs on their underwater mortgages in exchange for claims on a percentage of future appreciation of their homes, rich countries in Europe could possibly agree to a much bigger bailout for Greece (one, as Rogoff says, that's "actually big enough to work") in return for higher payments later if its economy outperforms.

????That way, both borrower and lender would have a stake in seeing the deal succeed. And perhaps more importantly, nobody is really getting a free ride – at least in principle.

????In the case of the U.S. housing market, this would potentially mean a win not only for homeowners who owe more on their homes than their properties are worth, but also a win for lenders and investors who would eventually be repaid for giving borrowers a break. Conversely, Europe's heavily indebted peripheral countries would get meaningful relief on their debt payments. Once these economies grow in healthier fashion – say 10 to 15 years from now – taxpayers would repay the rich countries via a portion of its GDP gains.

????Rogoff hasn't elaborated much beyond this, but it's almost assumed that any such plan would include easing austerity measures that the European Central Bank and International Monetary Fund have forced on Greece in order to secure its bailout money. These measures have created a double-edge sword for Greece, since it can't possibly repay the loans if it can't grow.

????True, it makes sense for a nation with huge debts to cut spending. But laying off thousands of workers and raising taxes has proven devastating on the Greek economy. GDP has shrunk more than anyone expected, falling 6% in 2010 and 7.3% during the three months ending in June. A further decline in growth could cause Greece to miss revenue targets and even seek more bailouts, which is largely why the market is pricing in the likelihood that Greece will eventually default.

????Greek bonds have plunged, putting the chance of default at more than 90%, according to Bloomberg. Two-year notes yield more than 70%.

????Now back to Rogoff's idea of giving Greece what would essentially be a long-term loan with delayed payments -- it has its drawbacks. Politicians would likely be against it, at least today. Germany is clearly fed up and resents having to be Europe's banker of last resort. And even though Germany could get substantial returns for funding bigger bailouts, this could still easily be viewed as rich states giving handouts to poor states that haphazardly spent beyond its means.

????The problem isn't just getting rich countries on board, however, says Alan Deardorff, associate dean of University of Michigan's Gerald R. Ford School of Public Policy. Greece would need an incentive to agree to what would essentially create a tax on any rise in income. Indeed, any collection on future GDP growth would have to be limited to a certain percentage so that Greece would have an incentive to grow its economy. And growth, at least in the long-term, would depend significantly on deep structural reforms in the state's economy.

????Nevertheless, if Rogoff's idea may not be politically feasible today, it's at least intellectually appealing. And something perhaps worth considering later.
