- 1.People Face Trade-offs: To get one thing, you give up another. (Example:studying vs. Sleeping.)Opportunity Cost: The cost of something is the value of the next best thing you gave up. (Example: The "cost" of a movie is the $15 plus the 2 hours of time spent.)Think at the Margin: Decisions are made by evaluating small, incremental changes. (Example: Choosing to have one more scoop of ice cream, not deciding whether to eat ice cream forever.)Incentives Matter: People change their behavior when rewards or punishments change. (Example: A sale at a store makes people buy more.)Trade Benefits All: Specialization and trade allow everyone to enjoy more goods at lower costs. (Example: You buy a phone from a tech company rather than trying to build one from scratch.)Markets are Efficient: The "invisible hand" of prices usually coordinates economic activity better than a central planner. (Example: Grocery stores stay stocked because of price signals, not government orders.)Government Can Help: Markets aren't perfect. Governments step in to fix "market failures" like pollution or monopolies. (Example: Environmental laws or anti-monopoly regulations.)
