5-4 Suppose the U.S. government determines that cigarette smoking creates social costs not
reflected in the current market price and equilibrium quantity of cigarettes. A study has
recommended that the government can correct for the externality effect of cigarette
consumption by paying farmers not to plant tobacco used to manufacture cigarettes. It also
recommends raising the funds to make these payments by increasing taxes on cigarettes.
Assuming that the government is correct that cigarette smoking creates external costs,
evaluate whether the study’s recommended policies might help correct this negative
externality.

6-2 For purposes of assessing income taxes, there are three official income levels for workers in a
small country: high, medium, and low. For the last hour on the job during a 40-hour
workweek, a high income worker pays a marginal income tax rate of 15 percent, a medium-
income worker pays a marginal tax rate of 20 percent, and a low-income worker is assessed a
25 percent marginal income tax rate. Based only on this information, does this nation’s
income tax system appear to be progressive, proportional, or regressive?
