Where does your stuff come from? Why have your clothes and personal items traveled all around the world?

Why People Trade 1.Suppose you couldn’t trade with anyone. What things would you have to give up? Everything you don’t make yourself! (Clothes, phones, bananas, heath care, etc) 2. Suppose you could only buy things that were produced in Arizona. Stopping trade would reduce people’s choices and make them worse off. Trade provides more choices => higher standard of living. 2

Absolute and Comparative Advantage 3

Suppose that you have the skills to be both an excellent fast food cook and an outstanding heart surgeon Your neighbor, Ronald, is less talented: he could be a mediocre fast food cook, but would make a terrible heart surgeon You have an absolute advantage over Ronald as a fast food cook You also have an absolute advantage over him as a heart surgeon

26 To become a cook, you must give up a far more lucrative career as a heart surgeon – your opportunity cost is very high Ronald, however, has a lower opportunity cost – to become a cook, he only has to give up a career as a parking attendant Therefore, Ronald has a comparative advantage in fast food cooking... even though you would be a better cook than him Which career should you choose?

27 Absolute advantage: the ability of an individual or group to do something better or more efficiently than another individual or group. Comparative advantage: the ability of an individual or group to do something at a lower opportunity cost than another individual or group The law of comparative advantage says that if people specialize in the activities in which they have the lowest opportunity cost – then everyone will be better off

28 Comparative and absolute advantage apply to countries! Climate, geography, the skills and size of its labor force, etc. – make a country good at producing some things and bad at others Countries have to make choices about what to produce To be efficient, they should produce those goods and services in which they have a comparative advantage

Economic Systems

Every society must answer three questions: 1. What should be produced? 2. How should it be produced? 3. Who gets to consume it? The way these questions are answered determines the economic system An economic system is the method used by a society to produce and distribute goods and services. 38

Economic Systems 1.Command Economy 2.Free Market Economy 3.Mixed Economy 39

Command Economies 40

In a command economy – also called a centrally planned economy – the government… 1. owns all the resources 2. answers all three economic questions Examples: Cuba, North Korea, former Soviet Union 41 Centrally planned economies often face problems of poor quality goods, shortages, and unhappy citizens. Why do you think this is?

Incentive: a thing that motivates or encourages someone to do something Government policies can influence the way people behave by changing people’s incentives These incentive changes may be intended or unintended Incentives

Socialism and Communism “From each according to his ability, to each according to his needs” Characteristics: 1.Abolition of private property 2.State ownership of all resources 3.Central planning 4.Elimination of social classes Karl Marx

Advantages and Disadvantages of Socialism/Communism 1. Equality! 2. Health care for all! 3. Jobs for all! 4. No class warfare because there are no classes! Pros Cons 1.Not much incentive to work too hard 2.Little incentive to innovate. No competition keeps quality of goods from improving. 3.Lots of opportunities for corruption 44

Incentives in the Soviet Union Soviet companies were not guided by prices or profit. Gov’t officials set arbitrary output quotas based on quantitative measurements. Businesses were paid based on meeting these quotas. 1.Because of weight-based production quotas for certain products, businesses would often fill products with lead to make them heavier that were almost too heavy to carry 2.Light bulb producers would only make tiny night light size bulbs because of production quotas based on number of bulbs produced. 3.Oil companies would intentionally drill many shallow holes when they knew that oil deposits are usually found in deep holes that require slower drilling, because companies were required to drill a certain number of feet 45

4. Construction superintendents would order workers to remove bathtubs from first floor and install them in the third floor while he slowly lead inspectors through apartment building, because businesses were paid based on number of apartments complete at time of inspection. 5. State-owned businesses would receive resources – e.g. functioning light bulbs – before the public did. Employees would often steal bulbs from work and replace them with burnt out bulbs. A black market for burnt out bulbs developed. Incentives in the Soviet Union

Do Now 1.Take out your Economic Systems notes 2.Answer the following in your notebook: In the United States, the wealthiest people must give 39.6% of their income (above ~$400,000) to the federal government as income tax. Meanwhile, 43% of low-income Americans pay no federal income tax at all. In your opinion, is this fair? Explain.

Review 1.What are the three economic questions that every society must answer? 2.Who decides how the three questions are answered in a command economy? 3.What are the main characteristics of a socialist/communist economic system? 4.What are some problems with socialism/communism?

Free Market Capitalism

Characteristics of Free Markets 1.Little government involvement in the economy. (Laissez Faire = Let it be) 2.Individuals own resources and answer the three economic questions. 3.The opportunity to make PROFIT gives people the INCENTIVE to produce quality items efficiently. 4.Wide variety of goods available to consumers. 5.Competition and self-interest work together to keep prices down and quality up. 51

Adam Smith and the “Invisible Hand” of the Free Market

How the free market regulates itself: Suppose consumers want laptops and are willing to pay for them… Businesses have an INCENTIVE to start making laptops to earn PROFIT. This leads to more COMPETITION…. Which means lower prices, better quality, and more product variety. We produce the goods and services that society wants because “resources follow profits.” End Result: Most efficient production of the goods that consumers want, produced at the lowest prices and the highest quality. 53

The Invisible Hand The idea that society’s goals will be met as individuals seek their own self-interest. Example: Society wants fuel efficient cars… Profit-seeking producers will make more. Competition between firms results in low prices, high quality, and greater efficiency. The government doesn’t need to get involved since the needs of society are automatically met. Competition and self-interest act as an invisible hand that regulates the free market. 54

Why socialism/communism fails: If consumers want laptops and only one state-owned company is making them… Other businesses CANNOT start making laptops. There is NO COMPETITION… Which means higher prices, lower quality, and less product variety. More laptops will not be made until the government decides to expand production The End Result: There is a shortage of goods that consumers want, produced at higher prices and lower quality. 55

56 1.Companies are greedy and will do anything to screw over consumers! Companies have an incentive to satisfy the needs of consumers. If they don’t they will go out of business. 2.Capitalism causes companies to outsource US jobs overseas. America suffers because companies want more profit! The number of people who benefit from lower prices far exceed the number of people who lose jobs 3.Capitalism only helps the rich. US companies enslave and exploit third-world workers in sweatshops! Sweatshop workers are not forced labor. They make the decision to work there voluntarily. Why? Although the working conditions are far below US standards, working in a sweatshop is usually better than the alternative Sweatshop wages in Vietnam, Honduras, and Nicaragua are often dramatically higher than the average wages in those countries Criticisms of Capitalism

Economic Freedom Heat Map

The degree of economic freedom in a country correlates strongly with per capita wealth

North Korea's GDP is $40 Billion South Korea's GDP is $1.45 Trillion (36 times greater).

Mixed Economies

Countries in blue have mixed economies

Mixed economies feature some characteristics of both command and market economies

Even the freest countries have some socialist characteristics The biggest knock on capitalism is that it leads to wealth inequality Many countries attempt to mitigate this with redistributive policies like progressive income taxes and generous social welfare programs The Socialist Temptation
