(1)Suppose you are driving on a highway with three lanes going in your direction and you come upon a toll plaza with six toll booths. Three toll booths are straight ahead in the three lanes of traffic, and the three other booths are off to the right. Which lane should you choose? There are usually enough people searching for the shortest line so as to make all the lines about the same length.
(2)The term profit in economics has a very precise meaning. Economists, however, often loosely refer to "good deals" or profitable ventures with no risk as profit opportunities. Using the term loosely, a profit opportunity exists at the toll booths if one line is shorter than the others. The general view of economics is that profit opportunities are rare. At any one time there are many people searching for such opportunities, and as a consequence few exist.
(3)At major banks in big cities, you can buy foreign currencies. The prices of these currencies are determined in world money markets. With dollars we can buy marks: with these marks we can buy francs: and with these francs we can buy back dollars. Can we make money on this transaction? If this is possible, we say that there are profit opportunities in the market. There are in fact almost never any profit opportunities of this kind in foreign currency markets. There are always individuals looking for such opportunities, and if any opportunity does arise it is quickly eliminated.
(4)If, for example, the mark-franc price is too low with respect to the other prices, there is an immediate rush to buy marks and sell francs, not by ordinary citizens at bank windows, but by a few large currency traders in Tokyo, London, or Zurich who watch prices every minute. Such a rush drives up the mark-franc price to the no-profit-opportunity point. Markets like this, where any profit opportunities are eliminated almost instantaneously are said to be efficient markets.
(5)The common language way of expressing the efficient markets hypothesis is "there’s no such thing as a free lunch". How should one react when a stock broker calls up with a hot tip on the stock market? With skepticism. There are thousands of individuals each day looking for hot tips in the market, and if a particular tip about a stock is valid there will be an immediate rush to buy the stock, which will quickly drive its price up. By the time the tip gets to your broker and then to you, the profit opportunity that arose from the tip (assuming that there was one)is likely to have been eliminated. Similar arguments can be made for bond markets and commodity markets. They are many "expert" in these markets, who take quick advantage of any news that affects prices.
(6)This economist’s view that there are very limited profit opportunities around can, of course, be carried too far. There are clearly times when profit opportunities exist. Someone has to be first to get the news, and some people have quicker insights than others. Nevertheless, news does get disseminated quickly, and there are thousands of people with quick insights. The general view that profit opportunities are rare is close to the mark.
In an efficient market, ______.
选项
A、profit opportunities remain a very brief time
B、only experts can grasp the profit opportunities
C、people without insights don’t get much profit
D、anyone who knows the hot tips can gain profit
答案
A
解析
细节题。第4段末句是对efficient market的定义,从该定义来看,判断一个市场是否有效与其获利机会存在的时间有关,由此可见,选项A的描述是正确的。
