Assume that air pollution from a copper smelter imposes external costs on people who

damages.
B) would be less than the amount at which the marginal benefit of pollution reduction
equaled the marginal cost.

One reason patent protection is vitally important to pharmaceutical firms is

costs higher than for any other business. Profits from patents are needed to pay these
labor costs.
