A government is considering levying a tobacco tax to raise revenue to finance health
care benefits. People for the tax argue that tobacco demand is price inelastic. Which of
the following statements is true?
A) The tobacco tax may not raise as much revenue as anticipated in the years to come
because tobacco demand is likely to become more elastic over time.
B) This is a very good way to raise revenue both in the short term and in the long term
because there are no close substitutes for tobacco.
C) This tax will not raise much revenue either in the short term or the long term because
demand is price inelastic.
D) No tax revenue can be raised in this way because tobacco sellers will just lower their
price by the amount of the tax, and therefore the consumer price of tobacco will not
change.

goods. If Guyana has a comparative advantage in the production of soybeans, then
Guyana
A) has a higher opportunity cost for soybeans, which means it should specialize in the
production of grapefruit and engage in trade.
B) has a lower opportunity cost for producing soybeans, but specialization is not
feasible because Paraguay has a lower monetary cost of soybean production.
C) has a lower opportunity cost for soybeans, which means that it should specialize in
production of soybeans and engage in trade.
D) should continue to produce soybeans, but only for domestic consumption, because
trade is not a viable option.
You value your economics textbook at $15. Someone else values it at $30, and that
person is willing to pay you $20 for your textbook. Would selling your textbook to this
person for $20 be Pareto efficient?
A) No, because you did not receive the maximum amount the other person would have
been willing to pay for the textbook.
B) No, the person paid you $20 for the book so his net benefit was $10, whereas your
net benefit was only $5. For this change to be Pareto efficient, each of you should have
the same net benefit.
C) Yes, because both of you are better off as a result of the trade.
D) Yes, because even though you gain from the trade and he loses, there is the potential
for you to compensate him for his loss.
