Chapter 1SectionMain Menu Chapter 1, Section 1: Scarcity and Factors of Production Essential Questions 1.Why are scarcity and choice the basic problems of economics? 2.What are the three factors of production? (Define each). 3.What are the two types of capital? (Define each). 4.What is the role of entrepreneurs? 5.Why do economists say all resources are scarce?

Chapter 1SectionMain Menu Ch 1, Section 1 Notes: Scarcity and Choice The study of economics begins with the idea that people cannot have everything they need or want. Need: something like air, food, or shelter and is necessary for survival. Want: at item that we desire but is not essential to survival. What is economics? The study of how people make choices to satisfy their wants and needs.

Chapter 1SectionMain Menu Ch 1, Section 1 Notes: Scarcity Scarcity occurs when there are limited quantities of resources to meet unlimited needs or desires Shortages occur when producers will not or cannot offer goods or services at current prices Not the same thing as scarcity because scarcity always exists. Shortages can be temporary. Goods: physical objects such as shirts or shoes. Services: actions or activities that one person performs for another. Living in a relatively wealthy country like America it is difficult to understand the idea of scarcity.

Chapter 1SectionMain Menu Ch 1, Section 1 Notes: The Factors of Production In addition to producing capital, people invest in themselves. Land: All natural resources that are used to produce goods and services. Labor: Any effort a person devotes to a task for which that person is paid. Capital: Any human-made resource that is used to create other goods and services. Physical Capital: Human made objects used to create goods and services. Human capital: The knowledge and skills a worker gains through education and experience.

Chapter 1SectionMain Menu Chapter 1, Section 2: Opportunity Cost Essential Questions 1.Why does every decision you make involve trade-offs? 2.What is the concept of opportunity cost? (Fully explain). 3.How will thinking at the margin affect decisions you make?

Chapter 1SectionMain Menu Ch 1, Section 2 Notes: Trade-offs and Opportunity Cost Trade-offs: are all the alternatives that we give up whenever we choose one course of action over others. Economists say that all individuals, businesses, and governments make decisions that involve trade offs. All individuals and groups of people make decisions that involve trade-offs. Guns and Butter: Refers to trade offs that nations face when choosing to make more or less military goods or consumer goods. Opportunity Cost: The most desirable alternative given up as a result of a decision.

Chapter 1SectionMain Menu The Decision-Making Grid Economists encourage us to consider the benefits and costs of our decisions.

Chapter 1SectionMain Menu Thinking at the Margin Economists look at decisions with one additional characteristic. Many decisions involve the adding or subtracting of one additional unit (like one minute or one dollar). When you decide how much more or less to do, you are thinking at the margin.

Chapter 1SectionMain Menu Chap 1, Sec 3: Production Possibilities Graphs Essential Questions 1.How do you interpret a production possibilities graph? 2.How do production possibilities graphs show efficiency, growth, and cost? 3.Why are production possibilities frontiers curved lines? 4.Why does a country’s production possibilities depend on its available resources and technology?

A production possibilities graph shows alternative ways that an economy can use its resources. The production possibilities frontier is the line that shows the maximum possible output for that economy.

An economy producing output levels on the production possibilities frontier is operating efficiently. Underutilization: any point inside the line indicates, using fewer resources that an economy is capable of using.

When this happens, the entire production possibilities curve “shifts to the right.”

Chapter 1SectionMain Menu Watermelons (millions of tons) Shoes (millions of pairs) Production Possibilities Graph Watermelons (millions of tons) c (14,12) d (18,9) Cost Cost: A production possibilities graph shows the cost of producing more of one item. Law of increasing costs: states that as we shift factors of production from making one good or service to another, the cost of producing the second item increases. To move from point c to point d on this graph has a cost of 3 million pairs of shoes.

Chapter 1SectionMain Menu Resources and Technology When economists collect data to create a production possibilities curve, they must determine which goods or services a country can produce given its current available resources. Includes land, labor, and capital of that country. Each kind of production method uses different technology. Economists must assess each country’s level of technology.
