8.  The Production Possibilities Curve (PPC) illustrates the concept of opportunity cost. Each point on the PPC means that every other point is a forgone opportunity.  The PPC bows outward because there are ever- increasing marginal costs to the production of any good. 8 Copyright © Cengage Learning. All rights reserved.

9.  Opportunity Cost: This is indicated by the negative slope of the PPC. As more of one good is produced, less of the other goods are produced.  Full Employment: Producing on the PPC  Unemployment: Producing inside the PPC  Economic Growth: Indicated by an outward shift of the PPC  Investment: Indicated by a trade-off between the production of consumption goods and capital goods.
