It measures the maximum number of outputs that can be achieved from a given number of inputs.

Slope is steep at B. High opportunity cost of guns. Guns B A The principle of increasing marginal opportunity cost states that opportunity costs increase as you produce more of one product.

All rights reserved. 2-12 Trade and Comparative Advantage The PPC is bowed because individuals specialize in the production of goods for which they have a comparative advantage. For a society to produce on its PPC, individuals must produce those goods for which they have a comparative advantage and trade for other goods. According to Adam Smith, humankind’s proclivity to trade leads to individuals using their comparative advantage.

Belgium has the comparative advantage in chocolate and specializes producing 4 tons (point E). Pakistan has the comparative advantage in textiles and specializes producing 4000 yards (point D). 1 2 3 4 4 3 2 1 5 Chocolate (in tons) Textiles (in thousands of yards) Belgium Pakistan A B C E D If both countries divide what is jointly produced evenly, they will both be consuming at point C, beyond both countries’ PPC.

Rationale for globalization of economies includes gains from trade due to comparative advantage. Individuals within nations, and even individual nations, can experience negative effects from globalization.

Critiques of Globalization 2-18 “Economic domination by the super- economic powers is sustained by proclaiming and promoting “free trade” enterprise…to the detriment of Third World economies especially Africa.” (Asogwa Chinwe, Nigerian political scientist) http://www.adbusters.org/content/joy -spoof

19. McGraw-Hill/Irwin Copyright  2008 by The McGraw-Hill Companies, Inc. All rights reserved. 2-19Summary The production possibilities curve (PPC) measures the maximum combination of outputs that can be obtained from a given number of inputs. According to the principle of increasing marginal opportunity cost, as production of one good increases, we must give up ever-increasing quantities of something else. Points inside the PPC are inefficient, points along the PPC are efficient, and points outside the PPC are unattainable.

20. McGraw-Hill/Irwin Copyright  2008 by The McGraw-Hill Companies, Inc. All rights reserved. 2-20Summary The rise of markets, specialization, trade, and competition have contributed to significant increases in output. By specializing in producing those goods for which one has a comparative advantage (lowest opportunity cost) one can produce the greatest amount of goods with which to trade. Specialization and trade shift the PPC out. We live in an ever-increasingly global economy. Both outsourcing and insourcing occur, based on comparative advantage.

To produce the third computer, production moves from alternative C to D. The marginal opportunity cost of the third computer is 70 – 40 = 30 books.

What is the opportunity cost of computer chips in each country? In which product should each country specialize? In the U.S. the cost of 1 computer chip is 80/80 = 1 video game. In Japan the cost of 1 computer chip is 80/40 = 2 video games. The U.S. should specialize in computer chips and Japan should specialize in video games.
