3. 3 FACTS! 1.Econ is a skills based course. Learning methodology resembles algebra more than history. 2.You MUST complete assignments BEFORE class Class time should be about sharpening skills, rather than just introducing/reviewing concepts. 3.Econ is a very intuitive subject, but it requires PRECISION. Many FRQ are similar to geometric proofs and cannot be “fluffed”

4. AP Exam The AP Macroeconomic exam consists of two parts. The first part is a 70 minute multiple choice text, the second part is a 60 minute free response section. When answering the free response students should use clear and concise language. Students may be asked to interpret graphs, or draw graphs to illustrate their analysis. Graphs must be properly labeled. Students must follow verb prompts and answer appropriately. For example: “Show” means to use a diagram to illustrate your answer. Correct labeling of all elements including the axes of the diagram is necessary to receive full credit. “Explain” means to take the reader through all of the steps or linkages in the line of economic reasoning. Graphs and symbols are acceptable as part of the explanation. “Identify” means to provide a specific answer that might be a list or a label on a graph, without any explanation or elaboration. “Calculate” means to use mathematical operations to determine a specific numerical response, along with providing your work.

6. What is Economics in General? Economics is the study of _________. Economics is the science of scarcity. Scarcity is the condition in which our wants are greater than our limited resources. Since we are unable to have everything we desire, we must make choices on how we will use our resources. In economics we will study the choices of individuals, firms, and governments. choices

7. Economics Defined Economics-Social science concerned with the efficient use of limited resources to achieve maximum satisfaction of economic wants. (Study of how individuals and societies deal with ________) Examples: You must choose between buying jeans or buying shoes. Businesses must choose how many people to hire Governments must choose how much to spend on welfare. scarcity

8. Keep in Mind… “ In spite of the practical benefits, economics is mainly an academic, not a vocational, subject…economics is NOT primarily a how-to-make-money area of study.”

9. Micro vs. Macro MICROeconomics- Study of small economic units such as individuals, firms, and industries (competitive markets, labor markets, personal decision making, etc.) MACROeconomics- Study of the large economy as a whole or in its basic subdivisions (National Economic Growth, Government Spending, Inflation, Unemployment, etc.)

10. Positive vs. Normative Positive Statements- Based on facts. Avoids value judgements (what is). Normative Statements- Includes value judgements (what ought to be). How is Economics used? Economists use the scientific method to make generalizations and abstractions to develop theories. This is called theoretical economics. These theories are then applied to fix problems or meet economic goals. This is called policy economics.

11. Would you see the movie three times? Notice that the total benefit is more than the total cost but you would NOT watch the movie the 3 rd time. Thinking at the Margin # Times Watching Movie BenefitCost 1st$30$10 2nd$15$10 3rd$5$10 Total$50$30

12. Marginal Analysis In economics the term marginal = additional “Thinking on the margin”, or MARGINAL ANALYSIS involves making decisions based on the additional benefit vs. the additional cost. For Example: You have been shopping at the mall for a half hour, the additional benefit of shopping for an additional half-hour might outweigh the additional cost (the opportunity cost). After three hours, the additional benefit from staying an additional half-hour would likely be less than the additional cost.

13. The MARGINAL ANALYSIS approach to decision making is more commonly used than the “all or nothing” approach. Notice that the decision making process wasn’t “should I go to the mall for 3 hours or should I stay home” In reality the decision making process started with “should I go to the mall at all.” Once you are there you thought “should I stay for an additional half hour or should I go.” Marginal Analysis

14. The MARGINAL ANALYSIS approach to decision making is more comely used than the “all or nothing” approach. Notice that the decision making process wasn’t “should I go to the mall for 3 hours or should I stay home” In reality the decision making process was “should I go to the mall at all.” Once you are there you thought “should I stay for an additional half hour or should I go.” Marginal Analysis You will continue to do something until the marginal cost outweighs the marginal benefit.

15. 5 Key Economic Assumptions 1.Society’s wants are unlimited, but ALL resources are limited (scarcity). 2.Due to scarcity, choices must be made. Every choice has a cost (a trade-off). 3.Everyone’s goal is to make choices that maximize their satisfaction. Everyone acts in their own “self- interest.” 4.Everyone acts rationally by comparing the marginal costs and marginal benefits of every choice 5.Real-life situations can be explained and analyzed through simplified models and graphs.

17. Scarcity

18. How to understand models/graphs. Models are simplified representations of reality. Economic models use graphs to understand concepts Begin by drawing the business cycle. Draw a simple Supply and Demand curve.
