10. Principles of Macro ECON 1110Spring 2006 Chapter 1 What Economics Is About

11. IMPORTANCE OF ECONOMICS • Good Citizenship in a Democratic Society • Improved personal decision making • Aids business decision making

12. MICRO vs. MACRO • MICROECONOMICS - the branch of economics that deals with the behavior and choices of an individual, firm, single industry, or market. • MACROECONOMICS - the branch of economics that deals with the aggregate behavior of the entire economy.

13. MICRO vs. MACRO (Example) • Macroeconomics does not try to answer the question of a) why do some countries experience rapid growth b) what is the rate of return on education c) why do some countries have high rates of inflation d) what causes recessions

14. MICRO vs. MACRO (cont.) • Determinants of inflation • Relative market shares of GM and Ford • Amount of imports and exports between U.S. and Japan • Growth of total production in U.S. • Level of output a firm produces

15. Important Macro Concepts Economic Growth Unemployment Inflation Economic fluctuations Productivity Government Spending and Taxation Monetary Policy

16. SCARCITY AND CHOICE • Unlimited Wants and Limited Resources Leads to SCARCITY • Scarcity Necessitates Choices • ECONOMICS is the study of CHOICES

17. Definition of Economics the study of how individuals and society CHOOSE • to employ SCARCE RESOURCES to produce goods and services • and to DISTRIBUTE them among the members of society

18. 4 CATEGORIES OF RESOURCES • LAND - natural resources • LABOR - physical and mental talents people contribute to the production process • CAPITAL - improvements to land such as buildings, machinery and tools • ENTREPRENEURSHIP - the talents that some people for organizing land, labor, and capital into new business opportunities.

19. THINKING LIKE AN ECONOMIST • Scarcity and its effect - Need for a rationing device: dollar price - Competition • Opportunity cost: What one has to give up in foregone alternative when any action is taking Ex) What is the opportunity cost to you of attending college? What was your opportunity cost of coming to class today?

20. Opportunity Cost (Example) • Compact Disc (CD): $10 each • Cassette Tape (CT): $5 each • Opportunity cost of one CD? • Opportunity cost of five CDs? • Opportunity cost of one CT? • Opportunity cost of four CTs?

21. THINKING LIKE AN ECONOMIST • Costs and benefits of decisions Decisions require comparing costs and benefits of alternatives. - Whether to go to college or to work?      - Whether to study or go out on a date?      - Whether to go to class or sleep in? • Decisions at the margin - Marginal changes are small, incremental adjustments to an existing plan of action - Marginal Benefit (MB) vs. Marginal Cost (MC)

22. SCIENTIFIC THINKING • The Association-Causation Issue (Fallacy of False Cause) - Association: if two events are linked or connected in some way ex) wash your car at 10:00  starts to rain at 10:30

23. SCIENTIFIC THINKING • Fallacy of Composition: The erroneous view that what is good or true for the individual is necessarily good or true for the group ex) tariffs • Ceteris Paribus Assumption: All other things held constant or nothing else changes

24. ECONOMIC CATEGORIES According to the type of questions economists ask • POSITIVE ECONOMICS - the study of “what is” in economic matters. • NORMATIVE ECONOMICS - the study of “what should be” in economic matters.

25. IDENTIFY THE FOLLOWING STATEMENTS AS POSITIVE OR NORMATIVE • The Stadium should be packed for Saturday’s UNT-UT Game. • The unemployment rate in Dallas is 5.3%. • A country as big as the United States should have a job for anyone that is willing to work.
