What is Economics? Chapter 1
Economics: The study of how people seek to satisfy their needs and wants by making choices
Needs vs. Wants Needs: things NECESSARY for survival Wants: things we desire but are NOT ESSENTIAL to survival
Scarcity Limited quantities of resources to meet unlimited wants
Shortage A situation in which a good or service is unavailable
Factors of Production Land Labor Capital –Human –Physical Remember these! You will hear them a lot this semester!
Land Natural resources (land, coal, water, forests, etc.)
Labor The effort people devote to a task for which they are paid
Capital –Physical: Human made objects used to create other goods and services –Human: The skills and knowledge gained by a worker through education and experience
Entrepreneurs Ambitious leaders who combine land, labor, and capital to create and market new goods and services.
Opportunity Cost There is no such thing as a free lunch!

Coffee Tea 50 Any production in this space is inefficient…you have the supplies but aren’t making the coffee or tea
Efficiency Efficiency means using resources in such a way as to maximize the production of goods and services. An economy producing output levels on the production possibilities frontier is operating efficiently.
Coffee Tea 50 Any production along this line is EFFICIENT
Growth Growth If more resources become available, or if technology improves, an economy can increase its level of output and grow. When this happens, the entire production possibilities curve “shifts to the right.”
