China Takes on the World By Michael Elliott China Takes on the WorldBy Michael Elliott
The railroad station in the Angolan town of Dondo hasn't seen a train in years. Its windows are boarded up, its pale pink façade crumbling away; the local coffee trade that Portuguese colonialists founded long ago is a distant memory, victim of a civil war that lasted for 27 years. Dondo's fortunes, however, may be looking up. This month, work is scheduled to start on the local section of the line that links the town to the deep harbor at Luanda, Angola's capital. The work will be done by Chinese construction firms, and as two of their workers survey the track, an Angolan security guard sums up his feelings. "Thank you, God," he says, "for the Chinese." That sentiment, or something like it, can be heard a lot these days in Africa, where Chinese investment is building roads and railways, opening textile factories and digging oil wells. You hear it on the farms of Brazil, where Chinese appetite for soy and beef has led to a booming export trade. And you hear it in Chiang Saen, a town on the Mekong River in northern Thailand, where locals used to subsist on whatever they could make from farming and smuggling--until Chinese engineers began blasting the rapids and reefs on the upper Mekong so that large boats could take Chinese-manufactured goods to markets in Southeast Asia. "Before the Chinese came here, you couldn't find any work," says Ba, a Burmese immigrant, taking a cigarette and Red Bull break from his task hauling sacks of sunflower seeds from a boat onto a truck bound for Bangkok. "Now I can send money back home to my family." You may know all about the world coming to China--about the hordes of foreign businesspeople setting up factories and boutiques and showrooms in places like Shanghai and Shenzhen. But you probably know less about how China is going out into the world. Through its foreign investments and appetite for raw materials, the world's most populous country has already transformed economies from Angola to Australia. Now China is turning that commercial might into real political muscle, striding onto the global stage and acting like a nation that very much intends to become the world's next great power. In the past year, China has established itself as the key dealmaker in nuclear negotiations with North Korea, allied itself with Russia in an attempt to shape the future of central Asia, launched a diplomatic offensive in Europe and Latin America and contributed troops to the U.N. peacekeeping mission in Lebanon. With the U.S. preoccupied with the threat of Islamic terrorism and struggling to extricate itself from a failing war in Iraq, China seems ready to challenge--possibly even undermine--some of Washington's other foreign policy goals, from halting the genocide in Darfur to toughening sanctions against Iran. China's international role has won the attention of the new Democratic majority in Congress. Tom Lantos, incoming chair of the House of Representatives Foreign Affairs Committee and a critic of Beijing's human-rights record, told TIME that he intends to hold early hearings on China, on everything from its censorship of the Internet to its policies toward Tibet. "China is thinking in much more active terms about its strategy," says Kenneth Lieberthal of the University of Michigan, who was senior director at the National Security Council Asia desk under President Bill Clinton, "not only regionally, but globally, than it has done in the past. We have seen a sea change in China's fundamental level of confidence." Blink for a moment and you can imagine that--as many Chinese would tell the tale--after nearly 200 years of foreign humiliation, invasion, civil war, revolution and unspeakable horrors, China is preparing for a date with destiny. "The Chinese wouldn't put it this way themselves," says Lieberthal. "But in their hearts I think they believe that the 21st century is China's century." That's quite something to believe. Is it true? Or rather--since the century is yet young--will it be true? If so, when, and how would it happen? How comfortable would such a development be for the West? Can China's rise be managed peaceably by the international system? Or will China so threaten the interests of established powers that, as with Germany at the end of the 19th century and Japan in the 1930s, war one day comes? Those questions are going to be nagging at us for some time--but a peaceful, prosperous future for both China and the West depends on trying to answer them now. WHAT CHINA WANTS--AND FEARS If you ever feel mesmerized by the usual stuff you hear about China--20% of the world's population, gazillions of brainy engineers, serried ranks of soldiers, 10% economic growth from now until the crack of doom--remember this: China is still a poor country (GDP per head in 2005 was ,700, compared with ,000 in the U.S.) whose leaders face so many problems that it is reasonable to wonder how they ever sleep. The country's urban labor market recently exceeded by 20% the number of new jobs created. Its pension system is nonexistent. China is an environmental dystopia, its cities' air foul beyond imagination and its clean water scarce. Corruption is endemic and growing. Protests and riots by rural workers are measured in the tens of thousands each year. The most immediate priority for China's leadership is less how to project itself internationally than how to maintain stability in a society that is going through the sort of social and economic change that, in the past, has led to chaos and violence. And yet for all their internal challenges, the Chinese seem to want their nation to be a bigger player in the world. In a 2006 poll conducted jointly by the the Chicago Council on Global Affairs and the Asia Society, 87% of Chinese respondents thought their country should take a greater role in world affairs. Most Chinese, the survey found, believed China's global influence would match that of the U.S. within a decade. The most striking aspect of President Hu Jintao's leadership has been China's remarkable success in advancing its interests abroad despite turmoil at home. Surprisingly for those who thought they knew his type, Hu has placed himself at the forefront of China's new assertiveness. Hu, 64, has never studied outside China and is steeped in the ways of the Communist Party. He became a party member as a university student in the early 1960s and headed the Communist Youth League in the poor western province of Gansu before becoming provincial party chief in Guizhou and later Tibet. Despite a public stiffness in front of foreigners, Hu has been a vigorous ambassador for China: the pattern was set in 2004, when Hu spent two weeks in South America--more time than George W. Bush had spent on the continent in four years--and pledged billions of dollars in investments in Argentina, Brazil, Chile and Cuba. While Wen Jiabao, China's Premier, was visiting 15 countries last year, Hu spent time in the U.S., Russia, Saudi Arabia, Morocco, Nigeria and Kenya. In a three-week period toward the end of 2006, he played host to leaders from 48 African countries in Beijing, went to Vietnam for the annual Asia-Pacific Economic Cooperation summit, slipped over to Laos for a day and then popped off for a six-day tour of India and Pakistan. For someone whose comfort zone is supposed to be domestic affairs, that's quite a schedule. "Look at Africa, look at Central America, look at parts of Asia," says Eberhard Sandschneider, a China scholar who is head of the German Council on Foreign Relations. "They are playing a global game now." As it follows Hu's lead and steps out in the world, what will be China's priorities? What does it want and what does it fear? The first item on the agenda is straightforward: it is to be left alone. China brooks no interference in its internal affairs, and its definition of what is internal is not in doubt. The status of Tibet, for example, is an internal matter; the Dalai Lama is not a spiritual leader but a "splittist" whose real aim is to break up China. As for Taiwan, China is prepared to tolerate all sorts of temporary uncertainties as to how its status might one day be resolved--but not the central point that there is only one China. Cross that line, and you will hear about it. This defense of its right to be free of interference has a corollary. China has traditionally detested the intervention by the great powers in other nations' affairs. An aide to French President Jacques Chirac traces a new Chinese assertiveness to the U.S. invasion of Iraq, saying, "They felt they can't allow that sort of meddling in what they see as a nation's internal affairs." But the same horror of anything that might smell of foreign intervention was evident long before Iraq. I visited Beijing during the Kosovo war in 1999, and it wasn't just the notorious bombing of the Chinese embassy in Belgrade that year that outraged top officials; it was the very idea of NATO's rearranging what was left of Yugoslavia. Wasn't the cause a good one? That didn't matter. China's commitment to nonintervention means that it doesn't inquire closely into the internal arrangements of others. When all those African leaders met in Beijing, Hu promised to double aid to the continent by 2009, train 15,000 professionals and provide scholarships to 4,000 students, and help Africa's health-care and farming sectors. But as a 2005 report by the Council on Foreign Relations notes, "China's aid and investments are attractive to Africans precisely because they come with no conditionality related to governance, fiscal probity or other concerns of Western donors." In 2004, when an International Monetary Fund loan to Angola was held up because of suspected corruption, China ponied up billion in credit. Beijing has sent weapons and money to Zimbabwe's President Robert Mugabe, whose government is accused of massive human-rights violations. Most notoriously, China has consistently used its place as a permanent member of the U.N. Security Council to dilute resolutions aimed at pressuring the Sudanese government to stop the ethnic slaughter in Darfur. A Chinese state-owned company owns 40% of the oil concession in the south of Sudan, and there are reportedly 4,000 Chinese troops there protecting Beijing's oil interests. (By contrast, despite the noise that China made when one of its soldiers was killed by an Israeli air strike on a U.N. post in Lebanon last summer, there are only 1,400 Chinese troops serving in all U.N. peacekeeping missions worldwide.) "Is China playing a positive role in developing democracy [in Africa]?" asks Peter Draper of the South African Institute of International Affairs. "Largely not." Human Rights Watch goes further: China's policies in Africa, it claimed during the Beijing summit, have "propped up some of the continents' worst human-rights abusers." China doesn't support unsavory regimes for the sake of it. Instead China's key objective is to ensure a steady supply of natural resources, so that its economy can sustain the growth that officials hope will keep a lid on unrest at home. That is why China has reached out to resource-rich democracies like Australia and Brazil as much as it has to such international pariahs as Sudan and Burma, both of which have underdeveloped hydrocarbon reserves. There's nothing particularly surprising about any of this; it is how all nations behave when domestic supplies of primary goods are no longer sufficient to sustain their economies. (Those Westerners who criticize China for its behavior in Africa might remember their own history on the continent.) But China has never needed such resources in such quantities before, so its politicians have never had to learn the skills of getting them without looking like a dictator's friend. Now they have to. WORKING WITH CHINA Assuming a bigger global presence has forced Beijing to learn the art of international diplomacy. Until recently, China's foreign policy consisted of little more than bloodcurdling condemnations of hegemonic imperialism. "This is a country that 30 years ago pretty much saw things in zero-sum terms," says former Deputy Secretary of State Robert Zoellick. "What was good for the U.S. or the West was bad for China, and vice versa." Those days are gone. Wang Jisi of Beijing University, one of China's top foreign policy scholars, says one of the most important developments of 2006 was that the communiqué issued after a key conference on foreign affairs for top officials had no reference to the tired old terms that have been standard in China's diplomatic vocabulary. Washington would like Beijing to go further. In a speech in 2005, Zoellick invited China to become a "responsible stakeholder" in international affairs. China's national interest, Zoellick argued, should not be narrowly defined, but would be "much better served by working with us to shape the future international system," on everything from intellectual-property rights to nuclear nonproliferation. Says Zoellick: "I'm not sure anyone had ever put it quite in those terms, and it clearly had a bracing effect." That would imply that China's behavior has changed of late. Has it? A U.S. policymaker cautions, "It's important to see the 'responsible stakeholder' notion as a future vision of China." In practice, this official says, "They've been more helpful in some areas than others." When the stars align--when China's perception of its own national interest matches what the U.S. and other international powers seek--that help can be significant. Exhibit A is North Korea, long a Chinese ally, with whom China once fought a war against the U.S. As North Korea's leader Kim Jong Il developed a nuclear-weapons program in the 1990s, China had to choose between irking the U.S.--which would have implied doing little to rein in Pyongyang--or stiffing its former protégé. Hu's personal preferences seem to have helped shape the choice. He is known to have been stingingly critical of Kim in meetings with U.S. officials. Michael Green, senior director for Asian affairs at the National Security Council until December 2005, says Hu had long indicated to visiting groups of Americans his skepticism about Kim's intentions. When the North finally tested a nuke last fall, China joined the U.S. and other regional powers in condemning Kim and supported a U.N. Security Council resolution sanctioning Pyongyang. Says a senior U.S. official: "If you asked experts several years ago, Could you imagine China taking these actions toward a longtime ally in cooperation with us and Japan? Most people would have said no." But nobody in Washington is getting carried away. Beijing has been helpful on North Korea because it's more important to China that Pyongyang not provoke a regional nuclear arms race than it is to deny the U.S. diplomatic support. Contrast such helpfulness with China's behavior on the dispute over Iran's nuclear ambitions. In December, China signed a billion contract with Iran to buy natural gas and help develop some oil fields, and it has consistently joined Russia in refusing to back the tough sanctions against Tehran sought by the U.S. and Europe. "It's hard to say China's been helpful on Iran," says a senior U.S. official, and there is little sense that such an assessment will change any time soon. Within its own neighborhood, there are signs that China's behavior is changing in more constructive ways. China fought a war with India in 1962 and another with Vietnam in 1979. For years, it supported communist movements dedicated to undermining governments in nations such as Indonesia, Singapore and Malaysia. Yet today China's relations with its neighbors are nothing but sweetness and light, often at the expense of the U.S. Absorbed by the arc of crisis spreading from the Middle East, the U.S. is simply less visible in Southeast Asia than it once was, and China is stepping into the vacuum. While American exports to Southeast Asia have been virtually stagnant for the past five years, Chinese trade with the region is soaring. In the northern reaches of Thailand and Laos, you can find whole towns where Mandarin has become the common language and the yuan the local currency. In Chiang Saen, signs in Chinese read CALL CHINA FOR ONLY 12 BAHT A MINUTE. A sign outside the Glory Lotus hotel advertises CLEAN, CHEAP ROOMs in Chinese. It is not aid from the U.S. but trade with China--carried on new highways being built from Kunming in Yunnan province to Hanoi, Mandalay and Bangkok, or along a Mekong River whose channels are full of Chinese goods--that is transforming much of Southeast Asia. Nor is China's smiling face visible only to its south. In a cordial state visit last year, Hu reached out to India--an old rival with which it still has some disputed borders. The two countries pledged to double trade by 2010 and agreed to bid jointly for global oil projects on which they had previously been competing. Hu has also sought to mend ties with Japan, another longtime rival, with whom China's relations have deteriorated in recent years. Last October, Hu met the new Japanese Prime Minister, Shinzo Abe, in Beijing just days after Abe took office, a visit Hu called a "turning point" in frosty relations between the two countries and which Premier Wen described as a "window of hope." WHOSE CENTURY? So, a China whose influence is growing but that is trying to ease old antagonisms--what's not to like? In one view, nothing at all, as long as China's rise remains peaceful, with China neither provoking others to rein in its power nor slipping into outward aggression. And yet as remote as a confrontation seems today, there are some China watchers who fear a conflict with the West could still materialize in coming years. They point to two factors: the modernization of China's defense forces and the risk of war over Taiwan. The authoritative Military Balance, published annually by the International Institute for Strategic Studies in London, estimates that China's military spending has increased nearly 300% in the past decade and from 1.08% of its GDP in 1995 to 1.55% in 2005. (By contrast, the U.S. spends 3.9% of its GDP on defense, and the U.S. economy is more than five times as big as China's.) China's most recent defense white paper, published last month, showed a 15% rise in military spending in the past year. Place such an increase in the context of Taiwan policy and you can start to feel queasy. The island has been governed independently since the defeated forces of Chiang Kai-shek retreated there in 1949. Beijing wants to see the island reunited with the mainland one day. The U.S., although it has a one-China policy and has no formal diplomatic mission in Taiwan, is committed to defend Taiwan from an unprovoked attack by China. In all likelihood, war over Taiwan is unlikely. After a miserable 200 years, China's prospects now are as bright as ever, the opportunities of its people improving each year. It would take a particularly stupid or evil group of leaders to put that glittering prize at risk in a war. Those in Taiwan who favor independence--including its President Chen Shui-bian--have singularly failed to win the support of the Bush Administration. "China," says Huang Jing of the Brookings Institution in Washington, "is now basically on the same page as the U.S. when it comes to Taiwan. Neither wants independence for Taiwan. Both want peace and stability." China's military buildup is best seen as a corollary of changes in Chinese society. Where Chinese military doctrine was once based on human-wave attacks, it now stresses the killing power of technology. There's nothing new, or particularly frightening, about such a transformation; it's what nations do all the time. If the Sioux hadn't learned how to handle horses and shoot Winchesters, they wouldn't have wiped out Custer's forces at the Little Bighorn. But other aspects of China's rise are real and troubling. China is a one-party state, not a democracy. Some U.S. policymakers and business leaders like to say there is something inevitable about political change in China--that as China gets richer, its population will press for more democratic freedoms and its ruling élite, mindful of the need for change, will grant them. Could be. But China is becoming richer now, and if there is any sign of substantial political reform--or any sign that the absence of such reform is hurting China's economic growth--it is, to put it mildly, hard to find. Does China's lack of democracy necessarily threaten U.S. interests? One answer to that question involves looking back to the cold war. The Soviet Union was not a democracy, and although the U.S. contested its power in all sorts of ways, American policymakers were content to live with the reality of Soviet strength in the hope (correct, as it turned out) that communism's appeal outside its borders would wither and Russia's political system would become more open. Is that how the U.S. should treat a nondemocratic China? In the forthcoming book The China Fantasy, James Mann, an experienced China watcher now at the Johns Hopkins School of Advanced International Studies, warns that living with a more powerful, nondemocratic Beijing would not be easy for the U.S. In crucial ways, the U.S. has less leverage over China than it ever had over the Soviet Union. China holds billions of dollars of U.S. government assets. American consumers have come to rely on cheap labor in China to provide goods at Wal-Mart's everyday low prices. The Soviet Union, by contrast, was an economic basket case: it had minimal foreign-exchange reserves and was desperate for U.S. and European high technology. This lack of leverage over Chinese behavior may make for an uncomfortable future. Mann sees a time when a powerful China not only remains undemocratic but also sustains unpleasant regimes in power, as it does today in such nations as Zimbabwe and Burma. Such behavior could make the world a colder place for freedom. Green, the former National Security Council staff member, agrees that China "wants to build speed bumps on the road to political globalization and liberalization" and is "particularly against any attempt to spread democracy." Sandschneider, the German China expert, says the Chinese "talk about peace and cooperation and development, which sounds great to European ears--but underneath is a question of brutal competition for energy, for resources and for markets." How can that competition be managed? And how can the U.S. and its allies convince the Chinese not to support rogue regimes? The key may be to identify more areas in which China's national interests align with the West's and where cooperation brings mutual benefits. China competes aggressively for natural resources. But as David Zweig and Bi Jianhai of the Hong Kong University of Science and Technology argued in Foreign Affairs in 2005, it would make just as much sense for the U.S. and China--both gas guzzlers--to pool forces and figure out how to tap renewable sources of energy and conserve existing supplies. For a start, the U.S. could work to get China admitted into the International Energy Agency and the G-8, where such topics are debated. The U.S. can also encourage China's leaders to recognize that irresponsible policies will diminish China's long-term influence. As China expands its global reach, it will find itself exposed to all sorts of pressures--of the sort it has never had to face before--to behave itself. Already, there are voices in Africa warning China that it is acting just like the white imperialists of old. In the Zambian city of Kabwe, where the Chinese own a manganese smelter, the local shops are stocked with Chinese-made clothes rather than local ones. In the oil-rich delta region of Nigeria, where Chinese rigs have a reputation for poor safety and employment practices, a militia group recently warned the Chinese they would be targeted for attack unless they changed their ways. There are some glimmers that such criticism is having an impact in Beijing. The Chinese, says Joshua Kurlantzick of the China Program at the Carnegie Endowment for International Peace, "are beginning to understand that some of their policies in Africa are turning people off" and have quietly turned to the U.S. and Britain for help in devising foreign-aid policies. A former senior U.S. official says Chinese officials have been closely monitoring the growing international distaste over its support for the Sudanese government. Congressman Lantos says younger Chinese diplomats "are embarrassed that the Chinese government is prepared to do any business with Sudan for oil despite what is happening in Darfur." Slowly, slowly, engagement with China, debate with its leaders--and the hope that as they see more of the world, they will understand why so many want to shun dictatorships--may all act to shade Chinese behavior. Such engagement will always be controversial. Like it or not, it involves cozying up to a nation that is not a democracy--and does not look as if it will become one soon. But China is now so significant a player in the global economy that the alternative--waiting until China changes its ways--won't fly. There is still time to hope that China's way into the world will be a smooth one. Perhaps above anything else, the sheer scale of China's domestic agenda is likely to act as a brake on its doing anything dramatically destabilizing abroad. On the optimistic view, then, China's rise to global prominence can
be managed. It doesn't have to lead to the sort of horror that
accompanied the emerging power of Germany or Japan. Raise a glass to
that, but don't get too comfortable. There need be no wars between
China and the U.S., no catastrophes, no economic competition that gets
out of hand. But in this century the relative power of the U.S. is
going to decline, and that of China is going to rise. That cake was
baked long ago. China is still a poor country (GDP per head in 2005 was ,700, compared with ,000 in the U.S.) whose leaders face so many problems that it is reasonable to wonder how they ever sleep. Its pension system is nonexistent. Corruption is endemic and growing. Protests and riots by rural workers are measured in the tens of thousands each year. The most immediate priority for China's leadership is less how to project itself internationally than how to maintain stability in a society that is going through the sort of social and economic change that, in the past, has led to chaos and violence. April 26 转贴一本书的前言http://www.pinggu.org/bbs/dispbbs.asp?boardID=18&ID=164166&page=1 金融衍生品定价模型-数理金融引论 的前言部分 很好玩 推荐一本好书《金融衍生品定价模型-数理金融引论》
前言
我们先从一个故事讲起吧。在从芝加哥大学拿到博士学位的两个月前,我开始在金融行业中找工作。我已经完成了博 士论文,然而,要找到一份工作并不容易。放弃了在大学里当教授的想法后,我花了一个月的时间去读John Hull 的那本书:Options and Other Derivatives”期权和“Futures,(《期货,其他衍生产品》)。帮我找工作的猎头打电话,说纽约有一家公司想尽快见我。那时候,我曾在三 家公司面试过,一家在俄克拉荷马州,一家在华盛顿,还有一家在纽约。可是,他们要么直接把我拒了,要么让我先等着,然后又开始不停地面试别人。猎头说这家 公司前景应该不错,不过他们不愿意为我支付飞机票。要么自己买票,要么就得放弃。我当时还只是个学生。去纽约的单程机票在机场当场买要五百美元,要是提前 几周预定的话,双程票才要一百五十美元。妻子和我商量了一下,然后帮我收拾了行李,开车把我送到火车站。我坐上了去纽约的火车。在火车上,我并没有睡意, 把Steven Shreve 在网上发的那份数理金融讲义翻来覆去地看,并设想着如果得不到这份工作我该怎么办。 飞机只要一个半小时的路程,火车走了差不多二十四个小时。火车到达纽约时,已是中午十二点了。我简短地拜会了一下我的猎头,就冲进了地铁,目的地是市区下城紧靠着华尔街的大通曼哈顿(Chase Manhattan) 大楼的第四十四层。 一点钟,一个和我年纪相仿的年轻人把我带进办公室,开始面试。“读过John Hull 的书?” “读过。” “如果我让你推导Black-Scholes 方程,你能做到吧?” “没有问题。” “既然没有问题,就不用了。他微笑着说:” ”“什么是波动率的偏态? “波动率的偏态就是市场上看涨、看跌期权在Black-Scholes 方程中的隐含波动率的一条曲线。” “所以说Black-Scholes 模型是错误的,对吧? ” “可以这么说。 ” “如果你卖了个看涨期权,想对冲风险,你是应该买股票,还是卖股票? ” “买股票” “为什么?” “因为看涨期权的Delta是正的。” “为什么看涨期权的Delta是正的?” “因为Delta等于N.d1/,所以是正的。” “不用公式好不好?” “那是因为看涨期权的价格曲线是递增的,而Delta是切线的斜率。” “假定IBM每股的交易价为75元。有个没有截止日期的触及生效期权,当IBM股价首次涨到100元时恰好支付1美元,否则期权继续有效。这个期权的价格是多少?忽略红利并且假定波动率是百分之二十,利率为零。” 我想了一会儿,用Black-Scholes方程给了解答。“0.75元。” 答案虽然正确,但他不是很满意,他给了我一个更直观的解释。 “其实这个触及生效期权的值根本不依赖于波动率。为了对冲IBM股价首次涨到100元时支付的1美元只要买百分之一股的IBM股票即可。而为了买百分之一股的IBM股票今天要0.75元,所以公式是不必要的。作为一个好的计量分析师,不能总是依赖公式。” “有 A,B两个足球队进行比赛,谁只要先积累地赢三场,谁就成为最后的冠军,因此它们最多比赛五场。你和另一个球迷将对每一场比赛打赌,赌注为x美元。如果你 赢了,你就得到x元,否则就输掉x元。每场比赛的赌注x元都是可调整的,完全由你决定。你的目标是通过一系列赌局,使得最后只要A队赢了你将赢得100 元,否则你将输掉100元。问题是第一场的赌注你该押多少呢?” 我用了一些符号表示比赛的输赢次序,作了十分钟的代数计算:“31.25元,对吧?” “为什么不用二叉树来计算呢?就跟计算期权价一样的道理。”他说。“如果你进入一个十年的利率交换,你付每三个月的LIBOR利率,接受每六个月的固定利率百分之五。结果第二天十年的利率交换固定利率涨了零点一个百分点,你是亏了还是赚了呢?你的盈亏的贴现值是多少?” “当然是亏了,由于我每年将要亏损一个百分点,而十年的贴现值之和是七点五左右,所以我亏损的贴现值是百分之七点五左右。” “假定Black-Scholes方程成立,且无股票红利。如果股票价格为100元。无风险利率为百分之五。考虑一个一年到期的欧式看涨期权,执行价格就是100元。如果波动率为零,那么看涨期权的价值应该是多少?再告诉我怎样对冲这个期权。” 我试着回答完他的问题,他就出去了,接着又进来了一个人。 “你好,我是公司的一个交易员。听说Pouria的问题你都答上来了。我有几个问题,你准备好了吗?” “你 听过俄罗斯左轮手枪问题吗?一把左轮手枪可以装六发子弹。一个赌徒在手枪里放了两发子弹,子弹在弹膛里是挨着的,然后把子弹轮盘随机地转了一下。他先朝自 己开了一枪。幸运的是,当然,你也可以说不幸的是,他还活着。接着轮到你。你是接过枪直接朝自己开枪,还是先随机地转一下轮盘再朝自己开枪呢?” “能不能不朝自己开枪呢?” “可惜这不是正确答案。” “那我就直接朝自己开枪吧,因为我有四分之三的活的概率。可是如果转一下轮盘再朝自己开枪的话,我就只有三分之二的概率了。” “一 个国王抓住了100个犯人。一天他决定把他们都处死。但是在处死之前,国王把他们召集起来,想给他们最后一次机会。他说将会给每个人一顶帽子戴在头上。每 顶帽子上随机写上1到100之间的一个数,作为编号,但允许重复。同时,每个犯人都可以看到其他人帽子的编号,但看不到自己的。每个人会得到一张纸条,犯 人自己在上面写下一个数。如果有一个犯人写下的数字和自己帽子的编号相同,所有的犯人都将被释放,否则所有人都将被杀掉。在国王给帽子编号之前,犯人们将 有十分钟的时间来讨论策略,在国王正式给帽子编号以后就不许再说话或者传递任何信息。这个策略将会是什么呢?” 当交易员问完了他的问题之后,风险组的头儿进来了。 “我问你个问题。看涨期权,同样执行价,同样到期日,波动率越高,价格是越高还是越低?” “波动率越高,不确定性越高,所以价格越高。” “看涨期权,同样执行价,到期日越长,价格是越高还是越低?” “时间越长,价格越高” “看跌期权是不是也这样呢?” “应该不是的。” 风险组的头儿走了,公司的总经理进来了。“我只有一个问题。我们两个人做个交易。假定S&P指数今天的价格是1000,利率是零。S&P指数的一个月的远期是多少?” “如果利率是零的话,一个月的远期就是1000。” “如果一个月后,我给你S&P的指数,你给我1000元,这个交易是公平的了?” “是公平的。” “如果一个月后,我给你1000除以S&P这么多的美元,你给我1美元。这个交易还公平吗?” 就这样,一个接一个的人进来面试我。有的问题我答得对,有的我一时也不知道。最后,差不多七点钟了,最先面试我的那个年轻人又进来了。 “正 常情况下,我们还会让你再来一次。然而,考虑到你住在芝加哥,这次我们给你破例。我们决定聘用你。这是我们提供的待遇:我们将给你两万五千元的安家费。你 第一年的年薪将是九万元,年终时,根据你的表现,你将获得至少六万元的奖金。你享受的福利还包括医疗保险和养老金,还有免费的健身会员卡,我们其实认为健 身会员卡比什么都重要。你要不要回去先考虑一下,再告诉我们?” “让我想一下。好吧,我接受。” 走出大通大楼时,我是一下子如释重负。我打电话给妻子,告诉她这个好消息。她对我说:“直接去机场的柜台买票,别管有多贵。忘了火车的事,快点回来吧。” 我马上打电话给了父母,告诉他们我终于有了工作,还说了薪水的情况,我的父亲在电话另一端喊到:“他们一定是疯了,一定是疯了!” 就 这样,我开始了华尔街的职业生涯。那个最先面试我的年轻人叫PouriaDehghanpour,是我日后工作的顶头上司。他是个很有才华的年轻人,教给 了我很多的金融知识。每年都会有很多毕业生在华尔街开始他们的职业生涯,学数学的、物理的、统计的、运筹的等等。无论专业背景是什么,他们都需要掌握这本 书中涉及的基本内容。 最新的金融定量方法主要是在西方金融行业中发 展起来。在日益开放的中国,金融专业人员对这些定量方法的需求将是巨大的。本书试图在此鸿沟上搭起一座桥梁。作者毕业于芝加哥大学 (UniversityofChicago),并取得博士学位,接着就开始在华尔街工作。这些年以来,我有机会在金融行业的许多领域中都工作过,包括股票 衍生品、固定收益类衍生品和信贷衍生品等。很长一段时间,我都觉得很有必要写一本关于我工作所需专业知识的书,作为船桨,引领来者。 数 理金融是一门需要大量高等数学知识的学科,包括微积分、概率论、随机分析、偏微分方程和傅立叶分析等等。然而,数理金融毕竟是为实际的金融操作服务的。所 以,本书的目的不是介绍所有这些专门领域的背景知识,而是希望尽可能地把隐藏在这些专业知识背后的一些重要的、直观的概念以及它们和实际操作的联系讲清 楚。这个领域中一个很重要的原则是:读者应该明白,任何数理金融理论和模型都有它们的优点和局限。从这个意义上说,所有的模型都是错误的。我在书中再三强 调,理论和模型都是在某些对现实世界做了过度简化后的条件下成立的。读者应永远带着这些条件去理解这些理论,并要思考如果假设的条件不满足时,如何修改理 论。 金融衍生品主要包括三个部分:股票衍生品,利率衍生品和信贷衍 生品。考虑到这些理论可能占的篇幅,我希望分三部分来介绍。这本书为第一部分,介绍股票衍生品。在未来,我还希望写书来专门介绍利率衍生品和信贷衍生品。 学习金融衍生品模型,有三个境界。如果去问从事数理金融工作的人什么是衍生品模型的核心,也许能听到两种回答。第一种回答是,衍生品定价很简单,就是要计 算概率的期望值。而所谓Delta就是期望值对其函数变量的一阶导数。第二种回答是,衍生品价格不过是在风险中性概率测度下取的期望值,或通过建立 Black-Scholes方程,求解得到。所谓风险中性概率测度,就是假设任何资产的收益率都是无风险利率。具体数值实现是建立树或者用有限差分法。在 作者看来,任何优秀的金融衍生品模拟都有两个最重要的任务:一是衍生品的复制与对冲策略,以减少最终收益的不确定性;二是让复制与对冲尽可能少地依赖于模 型本身。因为本书是讲金融模型理论的,书中千方百计地建立各种模型,然而目标却是要使我们的方法独立于模型。这看起来似乎自相矛盾。我想,一旦读完本书, 读者一定会对此有更深的理解。那将是第三个境界。 下面介绍一下本书 的框架。本书包括两个部分:基础理论部分和高等理论部分。基础理论部分可以作为金融衍生模型方向一学期课程的教材,高等理论部分可以作为数理金融研究生的 课程,或是讨论班的讲课内容。作者强烈建议在金融机构、共同基金或对冲基金工作的交易员、风险管理师或投资经理熟悉本书中的基础部分。 本 书第一章先从利率的概念出发,给读者讲述了金融中的最基本的原则:现金的时间价值。接着本章介绍了世界各金融中心的股票指数,并且给出了所有这些指数的历 史变化图。本章还介绍了几种常见的股票衍生品。这些衍生品中既有大家熟知的看涨、看跌期权,也有最近两年才开始交易的方差和波动率互换。 第 二章介绍了一些常见的衍生品的投资组合。为了让读者更清楚这些投资组合的交易头寸能做什么,我们对每个衍生头寸都给出了损益图。同时,我们第一次用无套利 的原理给出了股票或股票指数的远期与现价的关系。读者将第一次领略衍生品模型根本不是源于什么概率的期望,而是要考虑复制收益的策略。 第 三章仔细研究了看涨、看跌期权的基本性质。这些性质与任何概率论模型和偏微分方程模型都无关。这是对上述的第二个原则的一个很好的阐释。在通常的教科书 上,这些性质会被Black-Scholes公式的一些技术性分析所证明,但实际上它们可以简单地由收益函数推导出来。这些性质以及推导出它们的方法将给 读者展示一个最基本的原理:无套利原理。在第二章的后半部分,我还介绍了一个在期权市场寻找套利机会的有用算法。基于这个算法,读者可以开发出一个简单的 软件。我在介绍这个算法的同时,详细地讲述了如果套利机会存在的话,如何通过一系列的交易达到套利的目标。 第 四章将给读者简单地介绍一下随机分析理论。如果读者已经学过这部分内容,当然会有帮助。然而,为了逻辑的完备性,我们还是列出了后面将用到的主要随机分析 的结果。对从没有学过随机分析的读者,我的建议很简单:就使用普通微积分,只不过把其中的求导法则换成It.引理就行了。读者不应该只因为不懂随机分析而 觉得阅读本书有困难。作者在开始工作之前就从没有接触过随机分析。 第 五章推导著名的Black-Scholes偏微分方程,并对看涨、看跌期权求解。在推导过程中,我们用到了重要的“自融资”和“无套利”原理,尽管那时这 两个概念还没有正式的定义。之后本章推导了希腊字母的计算公式。最后指出这个模型实际上并不完美,因为它不能解释波动率偏态效应。 第 六章使用概率论的方法研究金融模型问题。通常有两种方法研究衍生品定价:偏微分方程方法和概率论方法。这两种方法可以通过Feynman-Kac方程联系 起来。讲金融模拟的有些书只讲其中一种方法。然而,我相信那样做不能够一览这个领域的全貌,也不能学到很多有用的方法。本章将证明金融市场的资产定价基本 定理,这个基本定理把无套利条件与相对价格鞅测度的存在性联系了起来。然后本章构造了风险中性测度,运用鞅的表示定理证明了看涨看跌期权可以通过动态地交 易标的资产来复制出相同的收益函数,并再次给看涨看跌期权定价。本章还将介绍在很多实际中非常有用的计价单位变换技术和Girsanov定理。 第 七章把介绍过的方法应用到很多新型期权上,包括二元期权,亚式期权和回望期权等。新型期权已被广泛地用于投资银行间的交易。这一章还会讲到Merton的 用期权来计算信贷风险的模型。读者可以看到股票衍生品与信贷衍生品之间的关系。其实这个模型已经被广泛地用于各个投资银行或对冲基金机构。这一章还将介绍 期权动态对冲过程中的一些相关问题,并且第一次推导出了区域波动率模型。 第 八章介绍模型的数值实现。数值方法是一个很广阔的领域,完全的介绍超出了本书的范围。这一章介绍了在华尔街实际操作中一些常用的方法:二叉树、 MonteCarlo模拟和有限差分法。MonteCarlo模拟是概率论中的方法,而有限差分则是偏微分方程中的方法。这两种方法都可以在日常工作中有 效地帮助我们求解模型。特别是,在利用介绍二叉树的同时,本章又在离散的情况下解释了风险中性概率的来源。 第九章讨论CAPM数学模型。这章的内容与本书的其他部分是相对独立的。然而,考虑到它数学上的完美及其在共同基金管理上广泛的应用,作者认为在介绍金融模型的书中值得用一章来介绍它。 第十章介绍傅立叶变换方法。近几年来,这种方法在华尔街的定量研究中起着越来越重要的作用。我们不仅介绍了傅立叶变换方法,而且还介绍了拉普拉斯变换的方法。这两种变化在复解析平面上可以统一起来。 第 十一章开始介绍经典的Black-Scholes模型之外的一些模型。本章给出了两个这样的例子:Merton的跳跃扩散模型和Heston的随机波动模 型。对这两个模型,本章都给出了闭形式公式。事实上,大多数现代金融模型都可以归结为一个跳跃扩散模型,或者一个随机波动模型。 第 十二章介绍一些常见的华尔街定量工作的面试问题,并给出了解答。这些问题不是一般的习题,它们多是工作人员在实际工作中碰到的问题。学习这些问题有助于读 者总结衍生品定价的基本方法和技巧。在本书的第二部分作者尝试着向读者介绍一些更新的金融数学模型,作为对第一部分的补充。 第 十三章讨论了一个理论问题:在给定波动率偏态信息的情况下,如何证明无套利的存在。我们解决这个问题的方法是证明了鞅测度的存在性。为此本章证明了事实上 存在无穷多个鞅测度,这些测度可以实现所有的波动率偏态。本章先证明离散情形,然后证明一般连续情形。这就使我们看到,Black-Scholes模型远 远不是唯一的模型,甚至区域波动模型也不是可以模拟整个波动率偏态的唯一模型。这一章可以被看成是第三章的引伸。 第十四章介绍区域波动模型。这是一个扩散模型,但是可以模拟整个波动率偏态,所以要大大优于传统的Black-Scholes模型,同时也对第十三章的理论作了具体实现。 第十五章介绍一种新型期权。这种期权经常在年金产品中出现,在美国人的退休计划中很常见。本章将给出这种新型期权的一个完整解析公式,这可以视为标准Black-Scholes模型的一个应用。 第十六章研究一类“可加泛函”及其定价。在这一章,读者将看到怎样把偏微分方程工具、概率论工具、傅立叶变换和拉普拉斯变换在一起综合地使用。特别地,这章的结果可以用于亚式期权和其他新型期权的定价。 第十七章研究回望期权的定价问题。这章用到的方法是跳跃过程方法的一个推广,因为我们只要假设资产遵从Lévy过程。接着,作者将在本章证明一个很有意义的结果:回望期权可以用普通的看涨、看跌期权在有限个点上静态地对冲。这又是前面列出的第一个基本原则的一个实现。 第十八章研究一个漂亮的结果:。这些结果源“Doob不等式及其应用”于作者企图给变异互换定价。这一章对感兴趣的读者来说将是概率论与经典分析的一次美妙结合。 第
十九章是作者与PeterCarr合写的一篇论文。后者是华尔街著名的定量分析家,曾获得风险杂志(Risk)授予的2003年度最佳衍生品专家奖。我们
将揭示一般期权与变异互换之间的关系。我们也将研究如何用变异互换对冲普通期权。特别地,我们将推广抛物型Black-Scholes方程为椭圆型偏微分
方程。进一步,我们给出一个闭形式解。在这一章,读者将看到鞅、偏微分方程、MonteCarlo模拟、变异互换和普通期权等等之间的紧密联系。这一章是
整本书的最后部分,其内容可以看做是随机波动模型的推广,同时也是本书研究衍生品模型的高潮。藉

2006年12月孙健 April 17 SJTU本科经济学phd/ms申请经验总结——谢绝转贴SJTU本科经济学phd/ms申请经验总结——谢绝转贴 首先声明:本人不是很典型,结果也比较烂,但是对于工科学校里面的经管类学生申请经济学希望有小小助益,择其不善而改之。根据分散投资降低系统风险原则,本人申请多国,多种学位,排名正态分布的投资组合。 背景:211典型工科学校本科金融学,gpa3.8/4.3,rank 8/52,g1370/5.0, t637/5.0,CUHK交换经历。 目标:经济学phd/master。 目标国家:Amer, Canada, England, Hong Kong,France,Singapore.
申请过程: 精华区里可以找到的我都跳过,只说重要的。
1选校及结果:分散风险原则。 [北美]个人观点phd在选校时只申请最好的,如果申到了就是最后一个学位,不可以申烂校。结果证明自己实力不够,衰晒。拿到ohio state a’d,鉴于它狂发ad,拒之。 北美eco master:少申两间就可以了,很少有奖学金,2年,较贵,70w左右。Duke录取,很痛苦地拒掉了它。 [加拿大]申经济学硕士,加拿大是英制,不可以直接phd。学费便宜,学制短1年的program有可能有奖学金。4月的时候仍然没出结果,效率较低。不是主攻对象。 [英国]硕士,ad易拿,offer难有,LSE拒我也在情理之中,录取比例接近1/80。家里有钱又没其他offer的,去英国吧,老牌教育大国。不同意英国硕士因为读的人多不值钱的说法,每个人preference不同,修行在个人。不是主攻对象。 [HK],那边的mphil有奖学金,待遇优厚,名额稀少,需要本人去面试。有交换经历较好。经济学方面,hkust最强,但是录取phd太少,一共4名,其中3人内部硕士直升,全球只招一个,浪费申请费,它的硕士全自费10w一年,容易申到所以没申它。Cuhk次之,全球eco排名100左右,给了面试机会,没去。Hku排100多。Cityu的international eco可能更强,最好有人内部推荐。 [法国]:巴黎高科工程师学位,笔试面试,考的数学很变态,拿到录取要学法语,以前貌似没有类似我的背景的人申请这间集团学校,运气成分很大。 [新加坡]:NUS学校项目mpp申请,简单笔试和面试,招生时间非常早,只要t,不是很了解。
2 ps:自己写,找native改。前后版本至少3版,对应不同学校量身定做,所以需要对申请学校有很好的了解。
3 推荐信:2封prof,1封Associate Prof。自己写,导师签字,套本校老师也是很重要的。如果有外国资深大学相关教授推荐最好。
4 其他:数学很重要,看NYU eco的网页会有非常详实的介绍,Cornell都说明需要线代,微分方程,交大管院的数学课不够,建议修数学二专。交大申请硕士的情况总的来说不错,每个申请的人都有不错的offer或ad,前途是光明的,道路是坎坷的,同志们加油,后面的路还长。
5 研究:本科生一般没有,但是要尽量参与,prp是一种方式。看个人的创造力了,eco不是理工科,没实验做(实验经济学除外……)
6 陶瓷:没有套,no comments.
7 保底:个人认为交大最差情况,英国全自费的master一定申的到,学校也是不错的学校,砸钱而已。保研拿来保底,理论上不可行,技术上不是不可以,但是严重伤rp的事情还是不要做的好。考研+出国双线程基本不可行。找工作,对于管院的人找个四大的工作保底还是比较容易的,还有人保底工作找的相当好,hsbc的牛人。提一点,找工作面试会占用很多时间,因为offer最后只会接受一个,所以如果是四大的话不用4间都投。投3家,笔试3家,一面2家,par面1家,offer一家——算下来安全性和效率兼顾。违约金一般三四千,ey出国违约不用付违约金,用几千块钱买个向下期权还是值得的。
梦想是美好的,现实是残酷的,怀揣梦想接受现实的人,才能生活得游刃有余。同意horsefoot的话,走出国这条路前,请先想好,自己是不是输得起。
致谢:感谢在这漫长的申请路上所有帮助过我的人,首先是我的父母,然后(排名不分先后),xiaoqiu, joannawang, Binglin, RR, Roger, Ziya, Paul, Thorsten, Billy Ou, Natalie, Nicky Shen, horsefoot, zhouyouoil, wyj, gogo, rabbit, 机器猫,Casper , ling, Nancy, zhuangzhuang, Tina, Yvonne, Oukai, Thomas Tao, Yudy jj, hzj, lgf, Oscar,所有在外国的师兄师姐,在这里就不公开你们的名字了,感谢在心中~ 还有所有的老师,Ms Pan, Mr Zhu, Mr Xiang, Mr Zhu.。。。师恩难忘。 所有的朋友谢谢你们的默默支持~ April 15 安吉毕旅4月13日14日,周五周六,天气晴转多云。地点:浙江安吉。人物:金融专业班及家属25人。
周五一大早,真的是一大早,5点半起床,6点半抢到校车位,7点半到徐汇校区,看到一辆蓝色大巴就停在眼前,美女导游,半个帅哥司机(好吧,只能是半个,因为从后面看还是满帅的……爬走……大连人来的)车牌号 辽 Axxxx,看来真是旅游旺季,从哪临时拉来的车子。 导游jj叫wenzhu,说“大家可以叫我小zhu”,我心里默念,这可是我经常对着流口水的帅哥的名字,打死也不能拿来叫你,于是,导游jj姓吴,我就一口一个“吴导”……开车之后才慢慢体会到导游jj和司机gg的伟大,一路从上海迷路到安吉,呼呼,好在大家都很好人,也很会自娱自乐,用车载音响开始唱起了K,不愧是金融班的,倒是挺会利用时间,不唱白不唱。沈老大自然是当之无愧的麦霸加k歌之王,有他在,我们的耳朵总不会太受罪,其他平时深藏不露的horsefoot同学、jiazheng、jianbo、guofeng都露了一手,金融班的mm就更赞了,用车载音响都能唱出ktv的效果,君君其实也很能唱的,真可惜上次班聚k歌的时候没有为我们献歌,不过我真正想看的是君君跳拉丁的样子,超有女人味。 中午吃过中饭,先游了大竹海,卧虎藏龙的拍摄地(小章同学和发叔叔在竹子上飞来飞去的那节)。山不高,爬起来也有些吃力,人老了,需要补钙啊……跑题了……大竹王据说进贡到北京农业博物馆展览去了,于是我们只能看见小竹王,直径17cm,其实也不是很粗。记得导游jj让我们猜竹王的宽度的时候,哪个人吼了一句,一个人可以抱住,我猜那个是大象腿,不是竹王。站在山顶的时候,君君提议我们来两句,于是憋啊憋,憋出一句“闲坐听竹海,遥望五女峰”交差,非常的惭愧。特别感动老婆还记得在杭州的时候,“断桥不断,寒山不寒,孤山不孤。皓月凭枝,清风绕耳……”我都快忘记了,那时候会拿出一张餐巾纸,然后用水笔开始写诗,不是一般的“作”。。。和老婆以及老公一起出游的生活真是美好啊,相亲相爱的齐人之福不是每个人都有这个福分的哦,而且还是这么体贴偶尔有一点小作的老婆,和温柔略带一点妩媚的老公,哈哈,我太幸福了。远远的看君君的时候,有一种遗世独立的感觉,虽然君君总说自己是因为近视所以视线飘忽,但是不得不承认,飘忽的很有水准。 第二个景点,九龙峡。话说龙有九子,一子囚牛,二子……(全部省略,大家google)自己查,分别代表山里不同的瀑布(大概吧)。风景秀丽的同时证明了自己的汉语水平有多差,睚眦,犴,如果不是有汉语拼音注释,只能指着牌子说“◎#%……%3瀑布”。我们的美女小殷在拍照的时候不幸落水,虽然只有鞋湿掉,不过我们女生一致用眼神杀死在旁边没拉住她的horsefoot同学,然后这个话题在晚上讨论的时候被扩展到了北方男人及上海男人的比较优势上面,具体内容省略…… 晚上的时候到住在农家乐,叫金鑫山庄,这个名字那叫一金光灿烂。。。想起来我的偶像焦恩俊给自己的别墅取的名字“蟠龙山庄”我就狂汗不止,说不定哪家农家乐或者乡间饭店就取了个这个名字。还是苏州园林的名字含蓄得体,留园,拙政,所谓大象无形,大音稀声,名如其人啊。住的地方比我想象中好多了,电视空调卫浴都有,二层小楼,背靠青山,下倚绿水,主要是非常的安静,除了麻将声音,没有了城市的喧嚣。美中不足,我们下来吃饭的时候饭菜全凉了,让不同的服务员帮我们热了无数次菜,才终于勉强完成了晚餐。好戏在后面,大家约好8点集合,horsefoot贡献一个“过,兵,乓”的游戏,一开始他解释完规则第一遍的时候,我和guofeng一脸问号的样子,然后horsefoot同学很耐心地解释完第二遍,我准备准备翻白眼加口吐白沫,我问guofeng听懂没有,他说没有,于是得出结论,是horsefoot的表达有问题,不是我的问题,逃走…… 期间还发生一个小插曲,就是新加坡国立的乌龙offer事件,我倒不是很care那个offer,只是比较心疼在漫游的时候接国际长途…… 周五是君君的生日,晚上和大伙一起策划帮她庆祝生日。特别感谢老婆,xinxin,tianyan,ada帮忙组织大家。虽然在荒疏野岭找不到蛋糕,只有妙芙和蜡烛象征一下,蜡烛也不够多,扛太多蜡烛怕压碎掉,但是我相信25个人一屋子满满的祝福也会带来温暖的。游戏环节我觉得是金融专业最high的一次,游戏的本质类似击鼓传花然后真心话大冒险,不过真心话大冒险的ideas都是巨搞的那种,交杯酒,massage,求婚,拉丁舞,2人1脚站立,跳舞,作强吻状,做鹌鹑状,在过程中评选出来了班花易儿,班草guofeng,沈老大一定相当郁闷为什么班草不是他,谁让他有家属了捏,咳咳。插花一下,在等待的时候抽空打了一圈麻将,人家单张听糊,鉴于时间快到了,于是找人代打,我刚让出位子,对家就放炮了,然后糊牌的不是我,伤心…… 晚上high到10点,还不尽兴,回到寝室洗洗弄弄,大家翻出吃的喝的开始女生最擅长的寝室夜聊,5个女生睡3张床,不知不觉居然聊到了2点,呵呵,老婆夸我睡觉的时候很乖,睡着了还会递被子给她,呵呵,君君嘛我就不在blog上面爆料了。 第二天早上去大汉72峰玩,我们讨论了半天这个汉字的由来,莫非当年有72个大汉在这里落草为寇,导游说是以前大旱,现在改了一个字,我大汗。。。基本上就是爬山,拍照,爬山,感觉山山水水的景色看多了,都差不多,黄山的翡翠谷据说也是卧虎的取景地之一,和这里差不多。山崖上的映山红开得很好看,因为膝盖前几天打太极的时候扭到了,下山的时候不是很舒服,所以基本上处于拣钱包状态,可惜什么也没拣到。 下午返城上海,我们出上海的时候走的是沪杭告诉,回上海的时候居然是沪宁高速,而且路经太湖,苏州,我地理不好,但是还可以判断一件事情,就是我们一路迷糊回到上海。小憩的时候隐约听见导游和司机的对话: 司机:“申苏浙皖高速好像不去上海啊?” 导游:“申就是上海。” 司机:“不是沪是上海吗?” 导游:“申和沪都是上海。” 司机:“那就好,这路就对了。我只知道沪是上海,怪不得上海的球队叫申花。” 我:“◎#¥%¥……#。”黑线+无语 从一星期前的开始选的地方,做预算,寻价,报名,收钱,订车,签约,出发,真象同好旅游的韩同学所说,组织20+的活动接近专业旅游了,上海所有的旅游车出租公司基本上都被我骚扰过了,不管之前有什么不愉快,在出去玩的那一刻起,统统忘记,做人要有始有终,但求无愧于心。等着回学校慢慢把图片贴出来,然后就要收收心了,不然考不出tef玩笑就开大了……
April 14 写拒信今天4.15就要到了,很早拒了ohio state的phd ad,今天终于没有选择的情况下拒了duke,很难受,鼠标点下去的时候真的很难受。 就像当年高考成绩出来的时候,正常人看到这个分数应该会笑得合不拢嘴,我进交大隐隐难受了一年,为什么要为了一点加分填交大,这片土地根本不是我向往的。直到今天phd申请完全结束全军覆没,我不想历史重演,不想后悔今天的选择。不能想,不敢想,其实如果我们当初在岔道路口向左转,而非向右,结果会不会不那么糟糕…… 要么改变偏好,要么改造你的环境。如果后者根本没能力去改变,那么我偏好什么,效用是什么根本不重要。 Enpc——究竟是一个问号还是一个句号! 本年度一大乌龙——NUS虚假offer事件NUS的MPP非常的令人崩溃,在风和日丽阳光明媚的周五下午,正在安吉竹海游山玩水的时候突然接到他们的越洋电话,说:我们刚才发了邮件给你,不过发错人了,抱歉请ignore之…… 虽然我早知道这个结果了,但是一封信里面出现了无数次我的名字的offer,怎么可能是一个小error…… 其实我不知道他们发邮件offer给我 已经在游山玩水了 突然接到国际长途……先说发错了 我问发错了什么 他们说offer…… 无语…… April 12 为“君”碾尽一池墨香junjun老公生日在即,和xiaoqiu一起送份礼物讨老公欢心~~ 当午后的阳光洒进窗台,走在交大的校园,路旁的樱花绽放,一个女孩,就这样轻轻地擦肩而过。她也许并不引人瞩目,就像淡淡的樱花,在这个美丽的季节,绽放出自己的美丽与芬芳。 很难想象,一个来自陕西的女孩,会散发出如此象江南水乡女子般温柔婉约的气质。从未见她大声地与人争执过,但在交大度过接近四个春秋,她却总是保留自己的原则,于是她的坚持,也这般让人动容。同窗三载,她就象一本书,吸引你去读,去了解,没有轰轰烈烈,没用海誓山盟,却有绵绵的细水长流。你高兴的时候,她会和你一起开心庆祝,烧菜点心样样精通,做出来的提拉米苏至今令人难以忘怀。你失落的时候,她会在一边静静地耐心地听,在你需要的时候,借给你一个坚定的肩膀,她说生活让我们长大。你需要帮助的时候,她毫不犹豫地伸出她的手——在炎炎夏日多走上几个小时的路,一定帮朋友买到要的东西,只不过因为,她说"答应了,就不可以让朋友失望。" 要求,但不苛求。高雅,但不高傲。这就是她,象一杯香茗,需要一个能够懂她,照顾她的人,细细地来品。 有人说"对你最好的人不是给你红酒的人,而是给你牛奶的人。"所以,作为室友的我,非常希望帮她找一位不需要很高大威猛,但是足够为她遮风挡雨,不需要很聪明或者诗词歌赋样样精通,但是能够理解她,懂她,爱她,和她一起向前走的人。 如果你看到这里,那么恭喜你,说明你是一个很有耐心的人,下面是mm的一点基本信息:身高 165cm, 85年的白羊座,爱好做甜点,音乐(mm的扬琴弹得很赞噢~),动画片,以及春天的午后在草坪上边晒太阳边做做小梦。 对于gg的要求,和mm站在一起看着舒服就好,内涵永远比外表持久。最好比mm大一点,大四或研究生gg最好,工作了的人士希望不要大mm超过10岁。地域没有特别要求,mm现在即将要出国,但是将来一定会回到来父母身边,所以希望gg是能够认真,对感情负责的人。 mm很真诚,这次挂牌也是征得父母同意情况之下,也希望gg能够以诚待之。专业摘手请手下留情。来信请至#$$%&*#$#%^%^@126.com,附上你的照片会让mm更好地认识你,mm说会认真阅读并回复每一封信。

又是樱花开的时节 传说樱花本是白色 因为在有人死在樱花树下 花瓣便被染成了淡淡的血色
这么美好的事物为什么要和这么残忍的传说连在一起呢
