The Choices Society Faces • Law of Increasing Relative Costs • As society attempts to produce more of a good, the opportunity cost of additional units generally increases. WHY?
The Choices Society Faces • Some resources better suited for certain products. • As you allocate more resources for that good, the production of that good will increase but at a greater cost for the good you are giving up because the resources are used in a less efficient manner. • The specializationof resources influence the shape of the production possibilities curve. • The more specialized the factor of production, the greater the opportunity cost and the curve in the PPC.
Economic Growth and the Production Possibilities Curve • Economic Growth: How can you increase the production of both M-16s and CD-Roms? • Occurs over a period of time. • Is illustrated by an outward shift of the production possibilities curve.
Economic Growth Allowsfor More of Everything M-16 Rifles (billions of units per year) CD-ROM Players (billions of units per year)
The Trade-Off Betweenthe Present and the Future • The PPC can be used to illustrate the trade-off between present and future consumption. • Consumption Goods- The use of goods and services for personal satisfaction. • Capital Goods- Goods used to produce other goods.
A B 4 5 Capital Goods and Growth • Consumer goods • Goods produced for personal satisfaction • Capital goods • Goods use to produce other goods Capital Goods per Year Consumption Goods per Year ($ trillions)
Future growth as a result of A on the left-hand diagram A B 4 5 Capital Goods and Growth Capital Goods per Year Recreation per year Today Consumption Goods per Year ($ trillions) Food per Year
Future growth as a result of C on the left-hand diagram C B 3 5 Capital Goods and Growth Capital Goods per Year Recreation per year A Today 4 Consumption Goods per Year ($ trillions) Food per Year
Capital Goods and Growth • Observations • Forgo consumption goods to produce capital goods • Increase in capital goods stimulates economic growth • In the future the economic system can produce more consumer goods • An increase in capital goods will lead to a higher rate of economic growth in the future
