Q. A university produces two commodities: research and teaching. The resources the university uses include faculty and staff, libraries, classrooms, labs and so on. The following schedule indicates some points on the university's PPF: A B C D E F G Research 900 750 600 450 300 150 0 Teaching 0 20 45 75 110 150 200 i) Does research production by the university exhibit increasing, constant or decreasing per unit opportunity costs? ii) Graph the university's PPF and indicate efficient, inefficient and impossible points. iii) Suppose the university is at point C but would like to alter production to point D. What would be the per-teaching unit opportunity cost of producing the extra teaching units? iv) What will happen to the PPF if the main laboratory partially burns down? Graph the new PPF. v) What will happen to the PPF if all of the campus resources are cut in half? Graph the new PPF.
