The Next Best Alternative Opportunity Cost The Next Best Alternative

The Opportunity Cost of doing something is the value of the next best alternative you give up. What is the opportunity cost of investing $500 in a new stereo system? What is the opportunity cost of going to college?

Opportunity cost varies from person to person What would you have purchased if you did not purchase the $500 stereo system? What could you “earn” if you don’t go to college

When we use resources to produce one good or service, the opportunity cost is that we cannot produce another good or service. When we make birdcages, we cannot use the same resources to make chairs.

How do you get an A in this class? Of course, hard work and fulfilling requirements If you are unable to achieve an A by fulfilling requirements, you may be able to buy one. The going rate is one million dollars

How do individuals or groups determine which specific goods or services to produce?

Can anyone tell me who this is. It’s “Wilson Can anyone tell me who this is? It’s “Wilson.” Tom Hanks only friend in what movie? *

Castaway in which he starred as a FED EX delivery man who is stranded on a desert island for 4 years. He discovers that he must do everything in order to survive. There is no one there to help him so he has to find out the best way accomplish this task by himself. Effectively, he is forced to live a life without specialization. The irony is that before he became stranded he helped deliver important packages around the globe so that people could specialize using their comparative advantage. This movie is poignant reminder of how difficult life would be if we had to do everything for ourselves. *

Law of Comparative Advantage The individual (or country) with the lowest opportunity cost of producing a particular good should specialize in producing that good. Specialization – The concentration of the productive efforts of individuals and firms on a limited number of activities

Babe Ruth

Opportunity cost is the key to comparative advantage: Individuals and nations gain by producing goods at relatively low costs and exchanging their outputs for different goods produced by others at relatively low cost. All potential trading partners can gain enormously through appropriate specialization and exchange.

Comparative & Absolute Advantage Comparative Advantage: The ability to produce something at a lower opportunity cost than other producers face Absolute Advantage: The ability to produce something with fewer resources than other producers use

Opportunity Costs and Efficiency Before Specialization Hours Worked Production and Consumption Alaskan 4 5 pounds of salmon 1 pound of coffee Brazilian 1 pound of salmon 5 pounds of coffee After Specialization Hours Worked Production Consumption Alaska 8 10 pounds Salmon 5 pounds of salmon 5 pounds of coffee Brazilian 10 pounds Coffee Trade enables each Alaskan to consume an additional 4 pounds of coffee per day, and each Brazilian to consume an extra 4 pounds of fish per day. Each group specializes in the form of production in which it enjoys a comparative advantage, and Alaskans and Brazilians both gain from trade. *

Suppose, for example, that a lawyer whose fees run $250 an hour types twice as fast as her secretary, whose wage is $12 hourly. She still gains by hiring the secretary. Despite her absolute advantage in typing, the lawyer’s comparative advantage lies in practicing law.

Comparative Advantage in Early America “Cash crops did not grow well in the Northern soil and climate. Southerners, on the other hand, had begun to reap huge profits from cotton by the mid-1790s. The South had very little incentive to industrialize. As a result, the North and South continued to develop two distinct economies, including very different agricultural systems.” ---The Americans

Comparative Advantage in Early America Northern Comparative Advantage Industry Southern Comparative Advantage Mass Cotton and Tobacco Production

Other Economic Principles in Early America Cost-Benefit Analysis of Slavery Opportunity Cost: Value of the next best alternative North: Chose no slavery Assume slavery (owning the laborer) is next best alternative to wage labor (renting the laborer). South: Chose slavery Assume wage labor is next best alternative to slave labor Question: Why did the benefits of the choice exceed the opportunity cost?

Other Economic Principles in Early America Factors influencing choice of labor type Relatively high wages in America Made renting labor expensive everywhere Fixed costs of overseeing and possessing slaves Larger firm size lowers average fixed cost Minimum average cost for slave production occurs at larger firm size. Climate and market differences promoted large firm size in South and small firm size in North.

Other Economic Principles in Early America Trade is mutually beneficial Northern farmers traded with Northern manufacturers Facilitated growth of Northern industry Relative wealth in industry ownership Southern farmers traded with European manufacturers Facilitated growth of Southern plantation system Less industrial growth in South Relative wealth in plantation ownership Beneficial trading was separating North and South

Other Economic Principles in Early America “American System” Tariff in 1816 on imported manufactured goods from Europe Designed by President Monroe to make North and South more interdependent Lobbied for by Northern Manufacturers Ushered in the “era of good feelings” Circular Flow of Income and Expenditure One person’s spending becomes another’s income

Other Economic Principles in Early America Restricting Trade Common Incentive: Shift the mutually beneficial trade my way Limit my competitors Tariff of 1816 Shifted South-Europe trade to South-North trade Strengthened Northern Manufacturing Influenced outcome of Civil War

Illustrating Comparative Advantage A Tootsie Roll Game Ignore absolute advantage to keep things as simple as possible Five “points” to use in production Country A: Twice as productive at producing cherry tootsies. Country B: Twice as productive at producing cherry tootsies.

Illustrating Comparative Advantage Country A: Production Possibilities Using Your 5 Points Your Choice? Allocation of Points Production Possibilities Points Used To Produce CHERRY ORANGE Tootsies Produced A 5 B 1 4 2 C 3 D 6 E 8 F 10

Illustrating Comparative Advantage Country B: Production Possibilities Using Your 5 Points Your Choice? Allocation of Points Production Possibilities Points Used To Produce CHERRY ORANGE Tootsies Produced A 5 10 B 1 4 8 C 2 3 6 D E F

Illustrating Comparative Advantage Which production combination did you choose? Cherry _________ Orange _________

Illustrating Comparative Advantage Trading Opportunity Would you like to replay the game? Produce first Then trade One cherry for one orange, or One orange for one cherry

Illustrating Comparative Advantage For Replay of the Game: Which production combination did you choose? Cherry _________ Orange _________ After trade combination?

Practice: Under current conditions, we can produce either 120 autos OR 3 aircraft, therefore: 120A = 3 B. Dividing both sides by 3 yields: 120/3 = 3/3 or 40A = 1B 40A = 1B is the number of autos given up to produce one aircraft or the opportunity cost of one aircraft

To Find Which Nation has the Comparative Advantage Find opportunity costs for both nations Compare each product’s opportunity cost from nation to nation Nation with the lowest opportunity cost has the comparative advantage If U.S. has 1A=.025B & G.B. has 1A=.05B, who has the comparative advantage?

Importance of Comparative Advantage To benefit from free trade, a nation does not have to be the lowest cost producer in the world A nation only has to have the lowest opportunity cost Remember, opportunity cost is what you give up to do something Use all the world’s resources in the relatively most productive ways
