2. AAn alternative that we sacrifice when we make a decision  A student skips school to go to ACL. Trade-off is giving up school for the concert GGuns or Butter: A cliché that refers to the trade-offs that nations face when choosing whether to produce more or less military or consumer goods

3.  The next best alternative given up as the result of a decision  Going back to the ACL example... › Grades have suffered due to skipping school › Decisions have a consequence or “cost”

4.  An opportunity cost must be desirable because there would be no meaningful decision to be made between a desirable option and an undesirable.

5.  “Thinking at the margin” means making a decision about how much more or less to do. It allows people to evaluate options based on available resources.

6.  To think about your next step forward › “Marginal” means “additional”  The first glass of cold water on a hot day quenches your thirst, but the next glass, maybe not so much. If you think at the margin, you are thinking about what the next additional action means for you. › Should I have another glass of water? › Is the benefit of one more unit greater than its cost?

7. AA curve depicting all maximum output possibilities for two or more goods given a set of inputs (resources, labor, etc.). The PPF assumes that all inputs are used efficiently. SShows all the goods and services that an economy is capable of producing given the factors of production available.

8. Illustrates scarcity, choices & opportunity costs Points on the curve show production amounts possible for 2 goods Capital goods Consumer Goods Point A

9.  Scarcity (Tradeoffs) › More resources for one product means less allocated to others  Law of Increasing Opportunity Costs › The more you want, the more you have to give up of other things  A perfectly efficient economy produces on the curve, instead of inside  Economic Growth › Goal of all economies › Moves by increasing factors of production

10.  Only 2 goods or services (or aggregates of goods or services) are produced.  Full and efficient use of all available resources.  Supplies of resources (i.e., land, labor, and capital) are fixed.  Technology is held constant.

11.  Using fewer resources than an economy is capable of using

12. AA broad term that implies an economic state in which every resource is optimally allocated to serve each person in the best way while minimizing waste and inefficiency. When an economy is economically efficient, any changes made to assist one person would harm another. In terms of production, goods are produced at their lowest possible cost, as are the variable inputs of production.

13.  Over time, most countries see an increase in their ability to produce goods and services. This “economic growth” is shown as an outward shift of the PPC and results from a variety of factors › Improved technology › Better education › Discovery of new resources

14.  Law that states that as we shift factors of production from making one good or service to another, the cost of producing the second item increases

15.  Underutilization is shown by any point that appears inside the production possibilities frontier

16. AA production possibilities curve shows the maximum possible output along the production possibilities frontier. If a country’s economic production is on the frontier, the economy is producing at top efficiency

17.  Opportunity cost can be illustrated by comparing the data at various points on the production possibilities frontier. As production of one element increases, the curve shows the decrease in production of the other element: opportunity cost.
