keen price

Competitiveness is usually taken to mean keen prices: if the price of cars produced in one country falls, foreign demand for them expands.

竞争力通常表现为低价：如果一国的汽车生产价下降，别国对该国的廉价汽车的需求就会上升。

Those who are particularly keen to get their hands on a copy of a new book, for instance, may be willing to pay a higher price for it, which may explain the persistence of expensive hardbacks.

比如那些特别热衷于获得版权书的人会愿意支付较高的价格。这可以解释坚持买昂贵精装书的现象。

Ricardo, but not Keen, used a "labor theory of price" in which a commodity's "innate worth" was the amount of labor needed to produce it.

但不是Keen，使用了“价格劳动论”，认为商品的“内在值”指生产它需要的劳动量。
