The scale of human tragedy caused by an earthquake and tsunami that has left so many thousands dead or missing can't be quantified. Economists, however, are doing their best to gauge just how much the destruction will cost both Japan and the world in economic growth.

　　地震和海嘯導(dǎo)致數(shù)千人死亡或失蹤，其對(duì)人類造成的破壞程度是無(wú)法被量化的。然而，經(jīng)濟(jì)學(xué)家正在竭盡全力衡量這次災(zāi)難在多大程度上會(huì)影響日本及世界的經(jīng)濟(jì)增長(zhǎng)。

　　Harder to estimate is how irrational fears could upend those calculations.

　　更難估計(jì)的是，非理性恐懼會(huì)如何改寫(xiě)這些預(yù)測(cè)和推算。

　　The financial damages will be enormous: Goldman Sachs puts the losses in buildings and production facilities at 16 trillion yen, or $193 billion, some 3.3% of the country's gross domestic product. In coming months, power shortages and supply-chain problems will slash the country's production of cars, electronics, machinery and other goods. The hit to tourism could last even longer.

　　Bloomberg News高盛（Goldman Sachs）認(rèn)為建筑和生產(chǎn)設(shè)施的損失達(dá)16萬(wàn)億日?qǐng)A（1930億美元），約占日本國(guó)內(nèi)生產(chǎn)總值（GDP）的3.3%。經(jīng)濟(jì)上的損失將是巨大的：高盛（Goldman Sachs）認(rèn)為建筑和生產(chǎn)設(shè)施的損失達(dá)16萬(wàn)億日?qǐng)A（1930億美元），約占日本國(guó)內(nèi)生產(chǎn)總值（GDP）的3.3%。未來(lái)幾個(gè)月，供電短缺和供應(yīng)鏈問(wèn)題將減少汽車、電子產(chǎn)品、機(jī)械等商品的生產(chǎn)。旅游業(yè)遭受的打擊可能會(huì)歷時(shí)更長(zhǎng)。

　　Yet the overall cost to Japan's growth, measured in GDP, should be minimal. As with past disasters such as the Kobe earthquake in 1995, a massive reconstruction effort will later push up spending on buildings, factories and even furniture and home appliances lost in the rubble, all of which could offset a slowdown in output.

　　然而，如果以GDP為衡量指標(biāo)，日本的經(jīng)濟(jì)增長(zhǎng)所付出的整體代價(jià)應(yīng)該會(huì)極小。如同1995年阪神大地震等過(guò)去的災(zāi)難一樣，大規(guī)模災(zāi)后重建會(huì)推動(dòng)被毀的建筑、工廠、甚至家具家電的開(kāi)支，這些都會(huì)抵消經(jīng)濟(jì)總量的減少。

　　"We expect by the fourth quarter, Japan will be on a clear economic recovery track," says Tomo Kinoshita, deputy head of Asian economics at Nomura. The Japanese bank has revised down its 2011 GDP forecast for the country by a mere 0.4 percentage points to 0.9%.

　　野村（Nomura）亞洲經(jīng)濟(jì)部副主管木下智夫（Tomo Kinoshita）說(shuō)，我們預(yù)計(jì)到第四季度，日本會(huì)走上明顯的經(jīng)濟(jì)復(fù)蘇軌道。這家日本銀行只將其對(duì)日本2011年的GDP預(yù)測(cè)數(shù)據(jù)降低了0.4個(gè)百分點(diǎn)，至0.9%。

　　For the rest of the world, a loss like that amounts to a rounding error. Bank of America Merrill Lynch figures even no growth at all in Japan this year would knock only a tenth of a percentage point off global GDP growth, to 4.2%.

　　對(duì)世界其他各國(guó)來(lái)說(shuō)，這種降幅相當(dāng)于四舍五入的誤差。認(rèn)為日本今年甚至不會(huì)取得增長(zhǎng)的美國(guó)銀行-美林（Bank of America Merrill Lynch）僅將全球GDP增長(zhǎng)率下調(diào)了10個(gè)基點(diǎn)，至4.2%。

　　A shift in manufacturing and tourism away from Japan could benefit its neighbors, too. Taiwan hotel shares rose Friday in expectation that evacuees and travelers from nearby Japan would provide a new source of business. A shortage of Hondas for sale could prompt more people to buy Hyundais.

　　制造業(yè)和旅游業(yè)從日本轉(zhuǎn)移也可能惠及它的鄰國(guó)。由于預(yù)期日本的撤離人員和游客會(huì)提供新的商業(yè)來(lái)源，臺(tái)灣的酒店股周五上漲。本田（Honda）汽車供應(yīng)短缺可能會(huì)使更多人買現(xiàn)代（Hyundai）汽車。

　　The problem is that what should happen isn't always what will happen. There are still too many unknowns. Lasting power shortages could cripple manufacturing and inflict worse damage on Japan's exports. Supply-chain disruptions may prove harder than expected to surmount, hurting not just the Japanese but importers of their machinery and high-tech goods in China, Taiwan and South Korea.

　　問(wèn)題在于，應(yīng)該發(fā)生的事并非總會(huì)如期而至。依然有太多的不確定性。供電短缺可能使制造業(yè)受損，對(duì)日本出口造成更嚴(yán)重的損失。供應(yīng)鏈中斷可能會(huì)比想象中更難克服，不僅會(huì)傷及日本人，還會(huì)傷及從日本進(jìn)口機(jī)械和高科技產(chǎn)品的中國(guó)、臺(tái)灣和韓國(guó)商人。

　　Of course, even worse is the risk that the efforts to repair damaged nuclear facilities fail to contain radioactive contamination, with enormous consequences to public health. The likelihood of that outcome appears to be diminishing as authorities make progress restoring power to cooling systems that prevent nuclear fuel from overheating.

　　當(dāng)然，更糟糕的是，修復(fù)受損核電站的努力存在無(wú)法抑制輻射污染的風(fēng)險(xiǎn)，會(huì)對(duì)公眾健康造成嚴(yán)重后果。隨著當(dāng)局對(duì)用于阻止核燃料過(guò)熱的冷卻系統(tǒng)的恢復(fù)供電工作取得進(jìn)展，出現(xiàn)這種結(jié)果的可能性似乎在逐漸降低。

　　But that doesn't eliminate the danger of panic.

　　但這并未消除恐慌的危險(xiǎn)。

　　Frightened shoppers across China, including Hong Kong, last week emptied their supermarkets of iodized salt in the sadly misplaced belief that it would offer protection against radiation sickness, or that irradiated seawater would contaminate future salt supplies. Signs that produce from around the nuclear-disaster zone contain low levels of radiation could spark broader food scares and result in unexpected shortages.

　　上周，因誤信碘鹽能夠防輻射病或受到輻射的海水會(huì)污染今后的食鹽供應(yīng)，包括香港在內(nèi)的一些中國(guó)城市的消費(fèi)者將超市的碘鹽搶購(gòu)一空。核泄漏災(zāi)區(qū)周圍的農(nóng)產(chǎn)品含有低水平輻射的跡象可能引發(fā)更大范圍的食品恐慌，并導(dǎo)致某些商品意外短缺。

　　It's not hard to imagine how panic might spread in the financial arena as well. In a report last week, Wells Fargo Securities warned of "psychological damage" that could lead to a selloff in the stock markets. "A full-blown financial contagion can not be ruled out," it added.

　　不難想象恐慌情緒會(huì)在金融領(lǐng)域如何蔓延。在上周的一份報(bào)告中，富國(guó)證券（Wells Fargo Securities）警告說(shuō)，“心理傷害”可能會(huì)引發(fā)股市拋售潮。它還說(shuō)，不能排除全面金融危機(jī)傳染的可能性。

　　When markets freeze up, so does economic activity, as consumers hoard their savings and companies rethink their investment plans. This is what creates recessions.

　　當(dāng)市場(chǎng)凍結(jié)時(shí)，經(jīng)濟(jì)活動(dòng)也就停止了，因?yàn)橄M(fèi)者會(huì)積累儲(chǔ)蓄，公司會(huì)重新考慮投資計(jì)劃。這樣就會(huì)造成衰退。

　　If we're not careful, fear, not logic, will create the reality that determines the outcome of events. Should that be the case, savvy investors might spot an opportunity to snap up cheap assets. For everyone else, the Japan's tsunami would end up leaving a wider swath of destruction than the spreadsheets are predicting.

　　如果我們不小心，恐懼將會(huì)左右現(xiàn)實(shí)，而不是邏輯。若果真如此，精明的投資者可能會(huì)注意到一個(gè)搶購(gòu)廉價(jià)資產(chǎn)的機(jī)會(huì)。對(duì)其他人來(lái)說(shuō)，日本的海嘯最終會(huì)帶來(lái)比經(jīng)濟(jì)學(xué)家所預(yù)測(cè)的更廣泛的破壞。
