单选题Most economists in the United States seem excited by the spell of the free market. Consequently, nothing seems good or normal that does not accord with the requirements of the free market. A price that is determined by the seller or, for that matter, established by anyone other than the aggregate of consumers seems harmful. Accordingly, it requires a major act of will to think of price-fixing (the determination of prices by the seller) as both "normal" and having a valuable economic function. In fact, price-fixing is normal in all industrialized societies because the industrial system itself provides, as an effortless consequence of its own development, the price-fixing that it requires. Modern industrial planning requires and rewards great size. Hence, a comparatively small number of large firms will be competing for the same group of consumers. That each large firm will act with consideration of its own needs and thus avoid selling its products for more than its competitors charge is commonly recognized by advocates of free-market economic theories. But each large firm will also act with full consideration of the needs that it has in common with the other large firms competing for the same customers. Each large firm will .thus avoid significant price-cutting, because price-cutting would be prejudicial to the common interest in a stable demand for products. Most economists do not see price-fixing when it occurs because they expect it to be brought about by a number of explicit agreements among large firms; it is not. Moreover, those economists who argue that allowing the free market to operate without interference is the most efficient method of establishing prices have not considered the economies of non-socialist countries other than the United States. These economies employ intentional price-fixing, usually in an overt fashion. Formal price-fixing by cartel and informal price-fixing by agreements covering the members of an industry are commonplace. Were there something peculiarly efficient about the free market and inefficient about price- fixing, the countries that have avoided the first and used the second would have suffered drastically in their economic development. There is no indication that they have. Socialist industry also works within a framework of controlled prices. In the early 1970"s. the Soviet Union began to give firms and industries some of the flexibility in adjusting prices that a more informal evolution has accorded the capitalist system. Economists in the Unites States have hailed the change as a return to the free market. But Soviet firms are no more subject to prices established by a free market over which they exercise little influence than are capitalist firms; rather, Soviet firms have been given the power to fix prices.

单选题"We"re using the wrong word ," says Sean Drysdale, a desperate doctor from a rural hospital at Hlabisa in northern KwaZulu-Natal. "This isn"t an epidemic, it"s a disaster. " A recent UNIEF report, which states that almost one-third of Swaziland"s 900,000 people are infected with HIV, the virus that causes AIDS, supports this diagnosis. HIV is spreading faster in southern Africa than anywhere else in the world. But is anyone paying attention? Despite the fact that most of the world"s 33.5 million HIV/AIDS cases are in sub-Saharan Africa—with an additional 4 million infected each year—the priorities at last week"s Organization of African Unity summit were conflict resolution and economies development. Yet the epidemic could have a greater effect on economic development—or, rather, the lack of it—than many politicians suspect. While business leaders are more concerned about the 2K millennium bug than the long-term effect of AIDS, statistics show that the workfare in South Africa, for instance, is likely to be 20% HIV positive by next year. Medical officials and researchers warn that not a single country in the region has a cohesive government strategy to tackle the crisis. The way managers address AIDS in the workplace will determine whether their companies survive the first decade of the 21st century, says Deane Moore, an actuary for South Africa"s Metropolitan Life Insurance Company. Moore estimates that in South Africa there will be 580,000 new AIDS cases a year and a life expectancy of just 38 by 2010. "We"ll be back to the Middle Ages," says Drysdale, whose hospital is in one of the areas in South Africa with the highest rates of HIV infection. " The graph is heading toward the vertical . And yet people are still not taking it seriously. " Most southern African countries are simply too poor to supply more than basic health services, let alone medicines, to confront the crisis. Patients in some government hospitals in Harare have to supply their own bedding, food, drugs and, in some cases, even their own nurses. Zimbabwe"s frail domestic economy depends to a large extent on informal enterprises and small businesses, many of which are going bankrupt as AIDS takes its toll on owners and employees. "The ripple effect is devastating," says Harare AIDS researcher Rene Loewenson. More ominous are the implications for South Africa with a sophisticated industrial infrastructure as well as a widespread informal sector. While the South African government is active in promoting AIDS education, it hasn"t the money, manpower or material to cope with the attack of AIDS.

单选题It was the best of times or, depending on your political and philosophical outlook, one of the foulest and most depraved. Rebellion seemed to be leaping from city to city, continent to continent, by some fiery process of contagion. Radical students filled the streets of Mexico city, Berlin, Tokyo, Prague. In the U. S. , Chicago swirled into near anarchy as cops battled antiwar demonstrators gathered at the Democratic Convention. And everywhere from Amsterdam to Haight-Ashbury, a generation was getting high, acting up. So, clearly, it was the year from hell--a collective "dive into extensive social and personal dysfunction," as the Wall Street Journal editorialized recently. Or, depending again on your outlook, a global breakthrough for the human spirit. On this, the 25th anniversary of 1968, probably the only thing we can all agree on is that '68 marks the beginning of the "culture wars," which have divided America ever since. Both the sides of the "culture wars" of the '80s and '90s took form in the critical year of'68. The key issues are different now--abortion and gay rights, for example, as opposed to Vietnam and racism--but the underlying themes still echo the clashes of '68: Diversity vs. conformity, tradition vs. iconoclasm, self-expression vs. deference to norms. "Question authority," in other words, vs. "Father knows best." The 25th anniversary of '68 is a good time to reflect, calmly and philosophically, on these deep, underlying choices. On one hand we know that anti-authoritarianism for its own sake easily degenerates into a rude and unfocused defiance: Revolution, as Abbie Hoffman put it, "for the hell of it." Certainly '68 had its wretched excesses as well as its moments of glory: the personal tragedy of lives undone by drugs and sex, the heavy cost of riots and destruction. One might easily conclude that the ancient rules and hierarchies are there for a reason--they're worked, more or less, for untold millenniums, so there's no point in changing them now. But it's also true that what "worked" for thousands of years may not be the best way of doing things. Democracy, after all, was onee a far-out, subversive notion, condemned by kings and priests. In our own country, it took all kinds of hell-raising, including a war, to get across the simple notion that no person is morally entitled to own another. One generation's hallowed tradition--slavery, or the divine right of kings--may be another generation's object lesson in human folly. '68 was one more awkward, stumbling, half-step forward in what Dutschke called the "long march" toward human freedom. Actually, it helped inspire the worldwide feminist movement.
