哲理的故事:1980年代,德国经历了数次通货膨胀之后,一位叫沃尔夫冈的烟草商发现:原来卖4.2马克一盒的万宝路香烟已经无利可图.他曾想过提高烟草的零售价,但又怕顾客一时难以接受。就在沃尔夫因为这个问题一筹莫展之时,他偶尔逛商店,偷听到了两个主妇的谈话。同样的两组茶杯,沃尔夫冈发现,在价格和数量这两个问题上,两位主妇似乎更愿意买数量少但价格低的商品。以此类推,如果在价格不变的情况下,直接减少万宝路的包装数量,消费者是不是也更容易接受呢? Philosophical Story: After Germany experienced several inflationary attacks in the 1980s, a tobacco company called Wolfgang discovered that Marlboro cigarettes, which sold forged a mark of 4.2 marks, have become unprofitable. He had thought of raising tobacco Retail price, but afraid of customers temporarily unacceptable. Just as Wolf waited for the question, he occasionally went shopping and overheard the talk of two housewives. The same two sets of teacups, Wolfgang, found that on the two issues of price and quantity, the two housewives seemed more willing to buy fewer but lower priced items. And so on, is it more acceptable to consumers if they directly reduce the number of Marlboro packages at the same price?
