单项选择题
Which of the following is least accurate regarding obstacles to the efficient allocation of resources in a competitive market（）
A. Taxes and trade restrictions impede the efficient allocation of resources.
B. Quotas result in production of less than the efficient quantity of the good.
C. Public goods, such as national defense, tend to be overproduced because they can be consumed by everyone whether they pay for the goods or not.
答案
参考答案：C
解析：
Public goods can be consumed by every member of a society, regardless of whether they paid for them or not. In a competitive market for public goods, fewer goods than the efficient quantity would be produced because it is not in each person’s interest to pay their share of the cost.
