A want is an item that we desire but that is not essential to survival. Because people cannot have everything they need and want they must consider their options and decide which choice best fills their needs What decisions do you need to make on a daily basis? –List them in 2 sections Needs & Wants

4. Chapter 1SectionMain Menu Scarcity Scarcity is the fundamental economic problem Not enough resources for everybody In order for something to be scarce, it must meet two criteria: Limited and Desirable These resources are called: Goods are physical objects Services are actions or activities that one person performs for another

5. Chapter 1SectionMain Menu Scarcity is not the same as shortage. A shortage occurs when producers will not or cannot offer goods or at the current prices Shortage can be temporary or long term Scarcity always exists because our needs and wants are always greater than our resource supply Goods and services are scarce because they are all made from resources that are scarce

6. Chapter 1SectionMain Menu The Factors of Production –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. 2 Types: Human & Physical

12. Chapter 1SectionMain Menu How do we make decisions? 1. Identify the problem. This includes defining what we want, and identifying the alternatives that move us to trying to satisfy our wants. Ex. Should I sleep, study, or hang out with friends tonight?, Do I want to have a fit body or not? 2. Analyze each alternative. We evaluate each alternative (trade-off) by considering the pros and cons of each, or as the economist might say, "after considering the benefits and costs of each."

13. Chapter 1SectionMain Menu 3. Make a choice. In this last step we choose the preferred alternative, rejecting the others. Economists explain that the next best alternative, or most desirable alternative given up as the result of your decision as an opportunity cost.

26. Chapter 1SectionMain Menu Efficiency Means using resources in such a way as to maximize the production or output of goods and services Underutilization: any point inside the line indicates an underutilization of resources Cost: an alternative we give up when we choose one option over the other Law of increasing costs: increasingly expensive trade- offs. This law states that as production switches from one item to another, more or more resources are necessary to increase production of the second item
