Study Notes
Principles of Economics
- Economics is the study of how society manages its scarce resources.
Scarcity
- Resources are limited, and therefore society cannot produce all the goods and services people wish to have.
- Scarcity means making decisions requires trading off one goal against another.
Principle #1: People Face Trade-offs
- To get one thing, we usually have to give up another thing (e.g., guns vs. butter, food vs. clothing, leisure time vs. work, efficiency vs. equity).
- "There is no such thing as a free lunch!"
- Efficiency means society gets the most that it can from its scarce resources.
- Equity means the benefits of those resources are distributed fairly among the members of society.
Principle #2: The Cost of Something Is What You Give Up to Get It
- Decisions require comparing costs and benefits of alternatives (e.g., whether to go to college or to work).
- The cost of something is what you give up to get it (opportunity cost).
Principle #3: Rational People Think at the Margin
- Marginal changes are small, incremental adjustments to an existing plan of action.
- People make decisions by comparing costs and benefits at the margin.
Principle #4: People Respond to Incentives
- Marginal changes in costs or benefits motivate people to respond.
- The decision to choose one alternative over another occurs when that alternative's marginal benefits exceed its marginal costs.
Principle #5: Trade Can Make Everyone Better Off
- People gain from their ability to trade with one another.
- Competition results in gains from trading.
- Trade allows people to specialize in what they do best.
Principle #6: Markets Are Usually a Good Way to Organize Economic Activity
- A market economy is an economy that allocates resources through the decentralized decisions of many firms and households as they interact in markets for goods and services.
- Households decide what to buy and who to work for.
- Firms decide who to hire and what to produce.
- Adam Smith's "invisible hand" concept: households and firms interacting in markets act as if guided by an "invisible hand" that leads to socially beneficial outcomes.
Principle #7: Governments Can Sometimes Improve Market Outcomes
- Markets work only if property rights are enforced.
- Property rights are the ability of an individual to own and exercise control over a scarce resource.
- Market failure occurs when the market fails to allocate resources efficiently.
- Government can intervene to promote efficiency and equity when the market fails (e.g., due to externalities or market power).
Principle #8: A Country's Standard of Living Depends on Its Ability to Produce Goods and Services
- A country's standard of living may be measured by comparing personal incomes or the total market value of a nation's production.
- Almost all variations in living standards are explained by differences in countries' productivities.
- Productivity is the amount of goods and services produced from each hour of a worker's time.
