Suppose that, during your afternoon shift working at the library, you could either reshelve books or process interlibrary loan (ILL) requests. Draw a production possibilities frontier (PPF) that describes your production trade-offs. Your production of each of these goods is subject to increasing relative costs in production, so be sure that your graph reflects this fact.

Now suppose that a new online request system increases your efficiency at processing ILL requests but does not affect your reshelving ability. Show, on the same graph, how this new innovation changes the PPF.
