der for Bill to pay Peter not to smoke, he will need to tip the waiter $10 to facilitate the transaction. Which of

5. To produce honey, beekeepers place hives of bees in the fields of farmers. As bees gather nectar, they polli-
nate the crops in the fields, which increases the yields of these fields at no additional cost to the farmer. What
might be a reasonable private solution to this externality, and how might the solution be reached?
6. The Coase theorem suggests that efficient solutions to externalities can be determined through bargaining. Un-
der what circumstances will private bargaining fail to produce a solution?
