不知你是否注意到这样一件事:一件耐用物品,即使只买了几个月,如自行车、汽车等,当你再卖出去的时候它已被折价百分之一、二十或更多。人们为什么会对一个很新的“二手货”打如此大的折扣呢?美国经济学家乔治·阿可列夫从不完全信息的角度给出了一个简单的解释。在旧货市场中,有些商品可能比另一些商品更次。卖者比买者更清楚所卖商品的质量,他知道他的旧品有些什么隐藏的缺陷,而买者只有当他买回去之后才知道这些缺陷。 I do not know if you have noticed such a thing: a durable item, even if it is only bought for a few months, such as bicycles, cars, etc., it has been discounted by 1 percent, 20 percent or more when you sell it again. many. Why do people discount such a large amount of “second-hand goods”? The American economist George Akirev gave a simple explanation from the perspective of incomplete information. In the flea market, some goods may be more frequent than others. The seller knows better than the buyer the quality of the goods sold. He knows what hidden defects his old product has, and the buyer only knows these defects after he buys it back.
