Detailed Explanation
1. People Face Trade-offs
Making decisions requires trading off one goal against another. For example, national
defense vs. consumer goods (guns vs. butter).
2. The Cost of Something Is What You Give Up to Get It
Known as opportunity cost. Example: Attending university may cost you a full-time salary.
3. Rational People Think at the Margin
Rational individuals make decisions by comparing marginal benefits and marginal costs.
4. People Respond to Incentives
Changes in costs or benefits influence behavior. Higher prices encourage production and
reduce consumption.
5. Trade Can Make Everyone Better Off
Trade allows specialization and increases the variety of goods and services available.
6. Markets Are Usually a Good Way to Organize Economic Activity
Market economies rely on decentralized decisions, with prices guiding resource allocation.
7. Governments Can Sometimes Improve Market Outcomes
Governments address market failures and promote equity where necessary.
8. A Country’s Standard of Living Depends on Its Ability to Produce Goods & Services
Productivity is the key determinant of living standards. Higher productivity means higher
income.
9. Prices Rise When the Government Prints Too Much Money
Excessive money printing leads to inflation, reducing the value of money.
10. Society Faces a Short-Run Trade-off Between Inflation and Unemployment
Stimulative policies may lower unemployment in the short run but increase inflation.
