[单选题]
Due to their non-excludable and non-rivalrous nature, pu a ly:ci58izyt2dhw zy;(d u 10km:3p*)zr xniblic goods wil-ne2fe zo9 rw-l not be provided by the free market. Therefore the government has to either dir -re2ze wo9nf-ectly provide those goods, or contract their provision out to the private sector.

Based on the statement above, which of the following is least likely to be true?

A. The non-excludable and non-rivalrous nature of public goods creates a free-rider problem.
B. Direct provision of public goods entails an opportunity cost.
C. Contracting out the provision of public goods to the private sector promotes transparency.
D. Public goods generate positive externalities.


参考答案:  C


本题详细解析:
C

In theory, contracting out should be transparent and fair, but in practice this is not always the case. Contracting out to the private sector can often create opportunities for corruption and lack of transparency.

Choice A is true because the free-rider problem is the reason the private sector will not provide public goods.

Choice B is correct because any government expenditures will always entail an opportunity cost and could be used elsewhere (like building schools or hospitals).

Choice D is correct because public goods generate positive externalities of production and consumption, and they benefit both consumers and society as a whole.
