Question 2

To produce honey, beekeepers place hives of bees in the fields of farmers. As bees gather nectar, they pollinate the crops in the fields, which increase 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?

Accepted Answer

One solution would be to have one person own both the farm fields and the beehives, in which case the externality is internalised. Another solution would be to have the farmer and beekeeper enter into a contract so that they can coordinate the number of beehives and acres of crops to maintain an efficient outcome.
