Consider the following cases of government intervention: regulations to limit air pollution, income support for the poor, and price regulation of a telephone monopoly. For each case,
(a) explain the market failure,
(b) describe a government intervention to treat the problem, and
(c) explain how "government failure" (Is it possible that there are, as well, "government failures," government attempts to curb market failures that are worse than the original market failures) might arise because of the intervention.
