28. Summary

29. Scarcity is the fundamental economic problem that human wants exceed the availability to time, goods, and resources. Individuals and society therefore can never have everything they desire.

30. Resources are factors of production classified as land, labor, and capital. Entrepreneurship is a special type of labor. An entrepreneur combines resources to produce innovative products.

31. Economics is the study of how individuals and society choose to allocate scarce resources. In order to satisfy unlimited wants. Faced with unlimited wants and scarce resources, we must make choices among alternatives.

32. Society Chooses Resources Scarcity Unlimited wants

33. Macroeconomics applies an economy wide perspective that focuses on such issues as inflation, unemployment, and the growth rate of the economy.

34. Microeconomics examines individual decision-making units within an economy. Microeconomics studies such topics as a consumer’s response to changes in the price of coffee and the reasons for changes in the market price of personal computers.

35. Models are simplified descriptions of reality used to understand and predict economic events. An economic model can be stated verbally or in a table, graph, or equation. If the evidence is not consistent with the model, the model is rejected.

36. Microeconomics examines individual decision-making units within an economy. Microeconomics studies such topics as a consumer’s response to changes in the price of coffee and the reasons for changes in the market price of personal computers.

37. Microeconomics examines individual decision-making units within an economy. Microeconomics studies such topics as a consumer’s response to changes in the price of coffee and the reasons for changes in the market price of personal computers.

38. Collect data and test the model Develop a model based on assumptions Identify the problem

39. Ceteris paribus holds “all other factors unchanged” that might affect a particular relationship. If this assumption is violated, a model cannot be tested. Another reasoning pitfall is to think association means causation.

40. Use of positive versus normative economic analysis is a major reason for disagreement among economists. Positive economics uses testable statements. Often a positive argument is expressed as an “if-the” statement. Normative economics is based on value judgments or opinions and uses words such as good, bad, oughtto, and ought not to.
