The Ten Principles of Economics
Mankiw organizes his textbook around ten core principles that serve as the foundation for understanding economics. These principles are divided into three categories: how people make decisions, how people interact, and how the economy as a whole works.
How People Make Decisions
1. People Face Trade-Offs: Every decision involves trade-offs. Choosing one option means giving up another. For example, spending time studying for an exam means less time available for leisure activities.
2. The Cost of Something is What You Give Up to Get It: This principle introduces the concept of opportunity cost, which is the value of the next best alternative forgone when making a decision.
3. Rational People Think at the Margin: Rational individuals make decisions by comparing the marginal benefits and marginal costs of an action. If the benefits outweigh the costs, the action is taken.
4. People Respond to Incentives: Economic behavior is influenced by incentives. When the costs of a good increase, consumers might buy less of it; conversely, lower costs can encourage consumption.
How People Interact
5. Trade Can Make Everyone Better Off: Trade allows individuals and nations to specialize in what they do best, leading to increased efficiency and mutual benefits.
6. Markets Are Usually a Good Way to Organize Economic Activity: In a market economy, decisions about production and consumption are guided by the interactions of buyers and sellers. Supply and demand determine prices, which in turn allocate resources.
7. Governments Can Sometimes Improve Market Outcomes: While markets are effective in many cases, there are situations where government intervention can correct market failures, such as externalities and monopolies.
How the Economy as a Whole Works
8. A Country's Standard of Living Depends on Its Ability to Produce Goods and Services: Higher productivity leads to greater income and improved living standards.
9. Prices Rise When the Government Prints Too Much Money: This principle addresses inflation, explaining how excessive money supply can lead to rising prices and reduced purchasing power.
10. Society Faces a Short-Run Trade-Off Between Inflation and Unemployment: In the short term, policies aimed at reducing unemployment may lead to higher inflation and vice versa, as illustrated by the Phillips curve.
