Bob is a keeper of honeybees. Nobody lives around. Bob can make $15 from each hive he keeps (PMB). His marginal cost function of keeping honeybees is given by MC=0.30Q. Now suppose Bob's neighbors are an elementary school and a nursing home. The more hives Bob keeps, the more students will be stung by bees. So Bob's hives have negative externalities. For every hive Bob keeps, his neighbors incur a cost of 0.1. That is, MD=0.15Q. Now what is the socially optimal number of hives? Show all of your work in terms of calculations. 1. a. Calculate private market Q and social optimal Q b. Calculate DWL at the socially optimal
