Suppose that Company A's railroad cars pass through Farmer B's corn fields. The railroad causes an externality to the farmer because the railroad cars emit sparks that cause $1,500 in damage to the farmer's crops.

Suppose that the railroad is not liable for any damage caused to the crops. Assume that there are no transaction costs. Which of the following characterizes the efficient outcome?
The farmer will pay the railroad $1,200 to purchase the grease so that no crop damage will occur.

When a certain nation abandoned a policy of prohibiting international trade in automobiles in favor of a free-tree policy, the result was that the country began to import automobiles. The change in policy improved the well-being of that nation in the sense that
the gains to automobile consumers in that nation exceeded the losses of the automobile producers in that nation.

world price of sugar.
Suppose your own demand curve for tomatoes slopes downward. Suppose also that, for the last tomato you bought this week, you paid a price exactly equal to your willingness to pay. Then
your consumer surplus on the last tomato you bought is zero.
Negative externalities lead markets to produce
greater than efficient output levels and positive externalities lead markets to produce smaller than efficient output levels.

What should the county do?
