问题     Lately, everybody from industrial designers to city planners claims to be looking after our aesthetic interests, and there is ample anecdotal evidence that, on the margin, people do put a higher premium on the look and feel of things than they once did. That is to be expected as society grows richer. But aesthetics is not the only value -- trade-offs must be made -- and aesthetic value is hard to measure. What is "it," after all? Aesthetics doesn’t come in neat units like microprocessor speed, calories, or tons of steel. Style is qualitative.
    The value of qualitative improvements poses tricky problems for economists. It is a major challenge to tease out how much consumers value each individual attribute that comes bundled in a given good or service. If you pay $2.99 for a toothbrush, how much of that is for the cleaning ability? How much for the feel of the handle? How much for the durability? How much for the packaging? How much for the convenient distribution to your comer drugstore? How much for the color?
    Economists use statistical techniques called "hedonic pricing" to try to separate the implicit prices of various characteristics. Essentially, they look at how prices go up or down as features are added or subtracted and try to figure out how consumers value the individual features. How much will consumers pay for an extra megahertz of computing speed, for instance?
    Not every characteristic is as easily measured as megahertz. The trickier the measurement, the more difficult the problem. For aesthetics, economists generally don’t even try. It’s just too hard. How do you account for the restaurant d écor or subtle enhancements in the taste of the food? How do you measure the increased value of a typeset resume, memo or client newsletter -- the result of ubiquitous word processors -- over an old-fashioned typed document?
    That sort of detail is simply lost in crude economic statistics. Many product characteristics -- from convenience to snob appeal to aesthetics -- are hard to quantify and so tend to be undercounted. The result is that the standard of living can change for the better without much notice.
    That is especially likely if products improve without becoming more expensive. Consumers are happier, but if they aren’t spending more money, no revenue increase shows up in the productivity statistics. This isn’t unusual in competitive markets. Shopping malls redecorate, and newspapers adopt color printing just to keep up with the competition. They aren’t able to charge more. They are just able to stay in business.
    When thinking about new products, producers face two challenges. First, they need to offer something whose value to the consumer is greater than its cost to produce and distribute. Increasing the surplus of value minus cost is where both higher living standards and higher profits come from. It is the measure of real economic improvement. The second challenge is, of course, to price the offering to maximize profit.
    As a general matter, aesthetics sells. But "as a general matter" obscures all the specifics that make or break a product: What exact design will you use? How will you manufacture it? What will you charge? And, given those decisions, how will customers respond?
    The answers can’t be found through a blackboard exercise. Price theory is a useful tool, but we can’t know in advance how much people will value the characteristics of a product they haven’t yet seen or compared with real alternatives. Even market research, while helpful, cannot duplicate real-life choices. Although we all have fun predicting and second-guessing business ideas, the only way to find out is through trial and error. Market competition is a discovery process that subjects business hypotheses to unsentimental testing.
    Some managers are better than others at identifying promising new sources of value, and some companies are better than others at operations and pricing -- the skills that determine whether a product that consumers do value will in fact be profitable. Market competition tests these theories and skills. And, like all competitions, this one has its failures, some of them beautiful.
    Not every attempt at improvement works out. Sometimes value does not exceed cost. Sometimes it does, but managers fall in love with their product, price it too high and drive away potential customers. Sometimes the coolest of the cool just can’t survive the heat. With 20/20 hindsight, it is easy to see that the pricey Cube was doomed. But nobody knew that a year ago.
According to the passage, the standard of living improves when ______.
选项 A、products are more aesthetically appealing
B、each product characteristic is quantifiable
C、there is a surplus of value minus cost
D、producers do not charge aesthetic enhancements
答案D
解析 该题要求理解第6、7段中的内容。产品的许多属性由于无法量化而被忽略，这会提高生活水平，特别是当产品质量提高而价格保持不变的时候。选项D为正确答案。
