单项选择题Disagreements among economists are legendary, but not on the issue of free trade. A recent survey of prominent economists both conservative and liberal concluded that an economist who argues for restricting international trade is almost as common today as a physician who favors leeching.
Why the consensus International free trade, economists agree, makes possible higher standards of living all over the globe.
The case for free trade rests largely on this principle: as long as trade is voluntary, both partners benefit, otherwise they wouldn’t trade. The buyer of a shirt, for example, values the shirt more than the money spent, while the seller values the money more. Both are better off because of the sale. Moreover, it doesn’t matter whether the shirt salesman is from the United States or Hong Kong (or anywhere else).
The vast majority of American manufactures face international competition. This competition forces companies to improve quality and cut costs. By contrast, protectionism encourages monopoly, lower quality and higher prices.
Americans pay an enormous price for protectionism over $60 billion a year, or $1000 for a family of four. Thanks to protectionism, for example, American consumers pay twice the world price for sugar.
Free trade also makes the world economy more efficient, by allowing nations to capitalize on their strengths. The United States has an advantage in food production, for instance, while Saudi Arabia has an advantage in oil. The Saudis could undertake massive irrigation to become self-sufficient in food, but it is more economical for them to sell oil and purchase food from us. Similarly, we could become self-sufficient in petroleum by squeezing more out of oil shale. But it is much less costly to buy some of our oil from Saudi Arabia. Trade between our two countries improves the standard of living in both.
Protectionism is both wasteful and unjust. It taxes most heavily the people who can least afford it. Thus, tariffs that raise the price of shoes burden the poor more than the rich. Despite the powerful case for free trade, the United States and the rest of the world have always been protectionist to some degree. This is because free trade benefits the general public, while protectionism benefits special interest groups, which are better organized, better financed and more informed. To make matters worse, much of what we hear on this issue is misinformation spread by the special interests themselves.
The economists ______.

A. agree on the restriction of internal trade
B. disagree whether to restrict free trade or not
C. hold different arguments because of their different interests
D. agree on free trade

1.单项选择题The traditional distinction between products that satisfy needs and those that satisfy wants is no longer adequate to describe classes of products. In today’s prosperous societies the distinction has become blurred because so many wants have been turned into needs. A writer, for instance, can work with paper and pencils. These are legitimate needs for the task. But the work can be done more quickly and efficiently with a word processor. Thus a computer is soon viewed as a need rather than a want.
In the field of marketing, consumer goods are classed according to the way in which they are purchased. The two main categories are convenience goods and shopping goods. Two lesser types are specialty goods and unsought goods. It must be emphasized that all of these types are based on the way shoppers think about products, not on the nature of the products themselves. What is regarded as a convenience item in France (wine, for example) may be a specialty good in the United States.
People do not spend a great deal of time shopping for such convenience items as groceries, newspapers, toothpaste, razor blades, aspirin, and candy. The buying of convenience goods may be done routinely, as some families buy groceries once a week. Such regularly purchased items are called staples. Sometimes convenience products are bought on impulse: someone has a sudden desire for an ice cream sundae on a hot day. Or they may be purchased as emergency items.
Shopping goods are items for which customers search. They compare prices, quality, and styles, and may visit a number of stores before making a decision. Buying an automobile is often done this way. Shopping goods fall into two classes: those that are perceived as basically the same and those that are regarded as different. Items that are looked upon as basically the same include such things as home appliances, television sets, and automobiles. Having decided on the model desired, the customer is primarily interested in getting the item at the most favorable price. Items regarded as inherently different include clothing, furniture, and dishes. Quality, style, and fashion will either take precedence over price, or they will not matter at all.
Specialty goods have characteristics that impel customers to make special efforts to find them. Price may be no consideration at all. Specialty goods can include almost any kind of product. Normally, specialty goods have a brand name or other distinguishing characteristics.
Unsought goods are items a consumer does not necessarily want or need or may not even know about. Promotion or advertising brings such goods to the consumer’s attention. The product could be something new on the market as the Sony Walkman once was or it may be a fairly standard service, such as life insurance, for which most people will usually not bother shopping.
A word processor can be looked on as satisfying ______ rather than ______ if it becomes the only means to an end.

A. a want, a need



B. a need, a want
C. a machine, a tool



D. a tool, a machine

2.单项选择题Every product on the market has a variety of costs built into it before it is ever put up for sale to a customer. There are costs of production, transportation, storage, advertising, and more. Each of these costs must bring in some profit at each stage: truckers must profit from transporting products, or they would not be in business. Thus, costs also include several layers of profits. The selling price of a product must take all of these costs (and built in profits) into consideration. The selling price itself consists of a markup over the total of all costs, and it is normally based on a percentage of the total cost.
The markup may be quite high, 90 percent of cost, or it may be low. Grocery items m a supermarket usually have a low markup, while mink coats have a very high one. High markups, however, do not in themselves guarantee big profits. Profits come from turnover. If an item has a 50 percent markup and does not sell, there is no profit. But if a cereal has an 8 percent markup and sells very well, there are reasonable profits.
While most pricing is based on cost factors, there are some exceptions. Prestige pricing means setting prices artificially high in order to attract select clientele. Such pricing attempts to suggest that the quality or style of the product is exceptional or that the item cannot be found elsewhere. Stores can use prestige pricing to attract wealthy shoppers.
Leader pricing and bait pricing are the opposites of prestige pricing. Leader pricing means setting low prices on certain items to get people to come into the stores. The products so priced are called loss leaders because little or no profit can be made on them. The profits are made from other products people buy while in the store. Bait pricing, now generally considered illegal, means setting artificially low prices to attract customers. The store, however, has no intention of selling goods at the bait prices. The point is to get people into the store and persuade them of the inferiority of the low priced item. Then a higher priced item is presented as a better alternative.
A common retail tactic is odd priced products. For some products of $300, the store will set the price at $295 or $299.95 to give the appearance of a lower price. Automobiles and other high priced products are usually priced in this manner. For some reason $7995 has more appeal to a potential car customer than $8000.
Bid pricing is a special kind of price setting. It is often used in the awarding of government contracts. Several companies are asked to submit bids on a job, and normally the lowest bidder wins. A school system may want to buy a large number of computers. Several companies are asked to submit prices, and the school district will decide on the best bid based as well on considerations of quality and service.
In the first paragraph, "markup" most probably means ______.

A. the amount by which a price is raised
B. margin
C. turnover




D. net profits
