a) Assuming they tneat repellent as a purely private good, how many units will each individual purchase? b) Suppose Abe is a hot shot biology major, and realizes that mosquito repellant is actually a pure public good. Intuitively he thinks that the three would be better off if they collectively purchased the repellant rather than individually buying repellant. Assuming that Abe is correct and repellant is a pure public good, what is the socially optimal number of repellant canisters for this three person collectivity? In the aggregate, is more or less repellant purchased after collective provision? How should the collective level of production be nanced, assuming the group does not want to run a deficit. c) Suppose the three decide to split the cost of each canister purchased evenly and that they will determine the number of canisters to buy via the method of majority voting. What is the outcome? How does it compare to the efficient outcome
