d.demand is inelastic.
____23.The deadweight loss from an economically inefficient situation is equal to

d.the increase in consumer surplus minus the increase in producer surplus that people could gain by eliminating that inefficiency.
____ 30.When the marginal product of labor falls,the marginal cost of output
a.falls,then rises.
b.becomes negative.
c.rises.
d.remains constant.
____ 32.Economies of scale
a.requires a change in the size of operations and therefore is a long-run consideration.

d.requires a change in the size of plant and therefore is a short-run consideration.

仅供参考：
15. A 当政府制定一个低于市场均衡利率的利率“天花板”时,大家都会去贷款,因为在资金成本低,有获利空间,这个时候就会出现信贷过剩.
19. A 其他条件不变,需求曲线弹性越大,消费者剩余越小.
20. A 其他条件不变,供给曲线弹性越大,生产者剩余越大.
23. C 生产无效率将导致供给减少,价格增加,消除无效率可以增加生产者和消费者剩余.
30. A 当产品需要的边际劳动力减少是,按常理产品的边际成本先随着减少,后因为规模收益递减而增加.
32.A 经济规模的改变意味着固定成本的投入或减少,因此是一个长期问题.
简单题我已经在另一个问题中回答过了.
再问： 只有15和20我们的答案是不一样的。15中credit是什么意思，贷款吗？20中我不明白，为什么弹性大，生产者剩余大？这里的弹性不是指 需求变化比价格变化的绝对值吗？
再答： 15题你们的答案是什么？ credit这里是信贷、贷款的意思，比单纯的“贷款”要广义一点，也包括其他的授信行为，像承兑汇票这些也算。 20题我做错了，应该是“供给弹性小，生产者剩余大”，应该选C，做太快，19到20题没转过弯来。
