单选题美国著名的经济学家阿瑟噢肯发现了周期波动中经济增长率和失业率之间的经验关系，即当实际国内生产总值增长相对于潜在国内生产总值增长(美国一般将之定义为3%)下降2%时，失业率上升大约1%；这条经验法以其发现者命名，称为奥肯定律。潜在国内生产总值这个概念是奥肯首先提出的，它是指在保持价格相对稳定情况下一国经济所产生的最大产值。潜在国内生产总值也称充分就业国内生产总值。 下列选项中与上述的分析方法相同的是哪一项?

单选题Most of the people who appear most often and most gloriously in the history books are great conquerors and generals and soldiers, whereas the people who really helped civilization forward are often never mentioned at all. We do not know who first set a broken leg, or launched a seaworthy boat, or calculated the length of the year, or manured a field; but we know all about the killers and destroyers. People think a great deal of them, so much so that on all the highest pillars in the great cities of the world you will find the figure of a conqueror or a general or a soldier. And I think most people believe that the greatest countries are those that have beaten in battle the greatest number of other countries and ruled over them as conquerors. It is just possible they are, but they are not the most civilized. Animals fight; so do savages; hence to be good at fighting is to be good in the way in which an animal or a savage is good, but it is not to be civilized. Even being good at getting other people to fight for you and telling them how to do it most efficiently--this, after all, is what conquerors and generals have done--is not being civilized. People fight to settle quarrels. Fighting means killing, and civilized peoples ought to be able to find some way of settling their disputes other than by seeing which side can kill off the greater number of the other side, and then saying that that side which has killed most has won. And not only has won, but, because it has won, has been in the right. For that is what going to war means; it means saying that might is right. That is what the story of mankind has on the whole been like. Even our own age has fought the two greatest wars in history, in which millions of people were killed or mutilated. And while today it is true that people do not fight and kill each other in the streets--while, that is to say, we have got to the stage of keeping the rules and behaving properly to each other in daily life--nations and countries have not learnt to do this yet, and still behave like savages. But we must not expect too much. After all, the race of men has only just started. From the point of view of evolution, human beings are very young children indeed, babies, in fact, of a few months old. Scientists reckon that there has been life of some sort on the earth in the form of jellyfish and that kind of creature for about twelve hundred million years; but there have been men for only one million years, and there have been civilized men for about eight thousand years at the outside. These figures are difficult to grasp; so let us scale them down. Suppose that we reckon the whole past of living creatures on the earth as one hundred years; then the whole past of man works out at about one month, and during that month there have been civilizations for between seven and eight hours. So you see there has been little time to learn in, but there will be oceans of time in which to learn better. Taking man's civilized past at about seven or eight hours, we may estimate his future, that is to say, the whole period between now and when the sun grows too cold to maintain life any longer on the earth, at about one hundred thousand years. Thus mankind is only at the beginning of its civilized life, and as I say, we must not expect too much. The past of man has been on the whole a pretty beastly business, a business of fighting and bullying and gorging and grabbing and hurting. We must not expect even civilized peoples not to have done these things. All we can ask is that they will sometimes have done something else.

单选题当一个国家出现通货膨胀或经济过热时，政府常常采取收紧银根、提高利率、提高贴现率等紧缩的货币政策进行调控。但是，1990年，日本政府为打压过高的股市和房地产泡沫，持续提高贴现率，最后造成通货紧缩，导致日本经济十几年停滞不前。1995年至1996年，泰国中央银行为抑制资产价格泡沫，不断收紧银根，持续提高利率，抑制了投资和消费，导致经济大衰退。 以下哪项陈述最适合作为上述论述的结论?

单选题Mass production, the defining characteristic of the Second Wave economy, becomes increasingly obsolete as firms install information intensive, often robotized manufacturing systems capable of endless cheap variation, even customization. The revolutionary result is, in effect, the demassification of mass production. The shift toward smart flex techs promotes diversity and feeds consumer choice to the point that a Wal-Mart store can offer the buyer nearly 110,000 products in various types, sizes, models and colors to choose among. But Wal-Mart is a mass merchandiser. Increasingly, the mass market itself is breaking up into differentiated niches as customer needs diverge and better information makes it possible for businesses to identify and serve micro markets. Specialty stores, boutiques, superstores, TV home-shopping systems, computer based buying, direct mail and other systems provide a growing diversity of channels through which producers can distribute their wares to customers in an increasingly demassified marketplace. When we wrote Future Shock in the late 1960s, visionary marketers began talking about "market segmentation". Today they no longer focus on " segments" but on " particles "—family units and even single individuals. Meanwhile, advertising is targeted at smaller and smaller market segments reached through increasingly demassified media. The dramatic breakup of mass audiences is underscored by the crisis of the once great TV networks, ABC, CBS, and NBC, at a time when Tele-Communications, Inc. of Denver, announces a fiber optic network capable of providing viewers with five hundred interactive channels of television. Such systems mean that sellers will be able to target buyers with even greater precision. The simultaneous demassification of production, distribution and communication revolutionizes the economy and shifts it from homogeneity toward extreme heterogeneity.
