1.1: Individual Choice, Scarce Resources, Choices, and Opportunity Costs
Read this section to learn about the basic problem of scarcity and the study of economics. Be sure to click through to read each of the pages in this section. As you read, reflect on the things that society needs and the resources that are needed for production like natural resources, money, labor, etc. Every society needs to take into account the problem of scarcity, and that decisions are needed to choose from producing one thing over another. An example is choosing between having a natural wild environment by not developing a piece of land, or developing that land for housing.
- Read this section to encounter the three fundamental questions that economists face and to learn about opportunity costs. Attempt the problems presented in the "Try It" section, and note how eventually every decision boils down to choosing between competing alternatives.
- Read this section to understand the concept of a budget constraint and how people make decisions when faced with this type of constraint. In economics, a budget constraint is a model that represents two possible things to choose from when spending some income. For example, suppose that you are a store manager and you have $100 to spend on two things for decorations for the store: flower arrangements at $10 each and posters at $5 each. A budget constraint for $100 will then be the different combinations with different number of flower arrangements and posters.
- Watch this video, which gives several examples of scarce resources that all of us confront as we make decisions on consumption and production.
- Watch this video, which explains the concept of scarcity and why people make choices in their best interests. Make sure that you go back to the reading from before titled "What Economics Is and Why It’s Important" as it explains to you the meaning of scarcity.
- This is an optional lecture and not a requirement of the course. In this unit, you learned that scarce resources underlie every economic decision that is made in society. You also learned that because of these scarce resources, there are trade-offs between alternate choices. In this guest lecture, Bjorn Lomborg advances this idea by discussing some pressing issues that need to be addressed. This talk should help you to identify the economic way of thinking, which will be elaborated upon in the next subunit.
