Scarcity, Opportunity Cost and Production Possibilities Curves
Scarcity necessitates choice. Co nsum ing or producing mo re of o ne com modity or service means con
suming or prod ucing less of someth ing else. The oppo rtun ity cost of using scarce resources for o ne commo dity or serv ice instead of so methi ng else is often represented in graphical form as a production possibilitieswrve.
Part A Use Figures 1.1 and 1.2 to ans wer Questions 1 and 2. Fill in th e ans wer blanks, or und erli ne the correct
answer in parentheses.

1. If the eco nomy represented by Figure 1.1 is pre sen tly produci ng 12 un its of Good B an d zero units of Good A:
(A) The opportun ity cost of increasing production of Good A from zero un its to o ne unit is the loss of un itfs ) of Good B.
(0 ) Th e opportunity cost of inc reasing product ion of Good A fro m one un it to two units is the
loss of unitts ) of Good B.
(C) Th e opportunity cost of increasing produ ction of Go od A from two uni ts to three units is the loss of unitfs) of Good O.
(D) This is an exam ple of (constant I increasing I decreasing I zero) oppo rtunity cost per unit for
Good A.
