Manufacturers sometimes discount the price of a product to retailers for a promotion period when the product is advertised to consumers. Such promotions often result in a dramatic increase in amount of product sold by the manufacturers to retailers. Nevertheless, the manufacturers could often make more profit by not holding the promotions.
Which of the following, if true, most strongly supports the claim above about the manufacturers' profit?
(A) The amount of discount generally offered by manufacturers to retailers is carefully calculated to represent the minimum needed to draw consumers' attention to the product.
(B) For many consumer products the period of advertising discounted prices to consumers is about a week, not sufficiently long for consumers to become used to the sale price.
(C) For products that are not newly introduced, the purpose of such promotions is to keep the products in the minds of consumers and to attract consumers who are currently using competing products.
(D) During such a promotion retailers tend to accumulate in their warehouses inventory bought at discount; they then sell much of it later at their regular price.
(E) If a manufacturer fails to offer such promotions but its competitor offers them, that competitor will tend to attract consumers away from the manufacturer's product.
这题我不懂的是题目是说M可以赚钱，可是D答案感觉是在说retailer可以赚钱阿?!!
题目说不搞promotion M反而能更赚钱
因为如果没有promotion的话，M就可以以正常价格卖东西给retailer
搞了promotion，retailer就用更低的价格买了本来需要更高价格买的东西，所以M赚得更少了
我想通了!!真是謝謝你阿!!
promote only benefit "retailer"!!!
In other word, manufacturer gain no benefit!!

搞了promotion，retailer就用更低的价格买了本来需要更高价格买的东西，所以M赚得更少了----问题是如果他没有PROMOTION的话这样一来根本就不会促销买气,因此他根本就无法赚更多钱,基本的经济学原理,通常厂商药降价就是希望把总收益上升,如果promotion不会赚更多钱的话,这样一般市场上的厂商是傻逼嘛,这样不就完全违背真实市场了,再说没有promotion虽然可以用正常价格卖出,使每单位利润上升,但是总利润却是下降的,在下小小的一番见解,希望大家给我指教一番
D应该是说如果manufacturer hold promotion，则retailers会利用promotion囤货，等promotion结束后以原价卖出，相当于promotion结束后会争夺manufacturer的市场，因为它只要以大于promotion小于原价的价格出售商品都会获利，而manufacturer此时则以原价出售商品，即竞争不过retailers啦，所以它用promotion会降低自己的利润
如果manufacturer不进行promotion，一直以原价出售，retailers就不会囤货再与它竞争啦。
做个极端的假设，promotion时manufacturer以50元每个的价钱卖出啦100产品，但promotion结束后卖不出去啦，即总利润5000.
不进行promotion，以原价100元每个的价钱卖出100产品，即使之后卖不动啦，总利润也有10000，比promotion时多出了5000
