Here are some "Tips for Hunting for Economics Everywhere" from Daniel S. Hamermesh (2004)

1. Look at your own behavior and your friends' and family's behavior when you buy things or undertake a new activity. How does scarcity lead to that behavior?

2. Consider what is given up when another thing is chosen. What is the true opportunity cost of choice?

3. Look at the choices society makes when the government spends tax dollars. What is being obtained, and what is it worth? What is forgone when the choice is made?

4. Look for cases where the government or another outside force restricts the ability of prices to equilibrate a market.

5. Look at how people change their behavior when the actual or implicit price of an activity or good changes.

6. Consider how purchases change as income changes. How do these differences in purchases vary by demographic characteristics?

7. Look at your own behavior as it reflects the satisfaction you get from different activities. Is it rational in terms of your objectives? Does it reflect diminishing marginal utility?

8. What does behavior imply about attitudes toward risk? What does it show about altruism or envy?
