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.
№14 слайд
Содержание слайда: Principle #2: The Cost of Something Is What You Give Up to Get It.
Decisions require comparing costs and benefits of alternatives.
Whether to go to college or to work?
Whether to study or go out on a date?
Whether to go to class or sleep in?
The opportunity cost of an item is what you give up to obtain that item.
№15 слайд
Содержание слайда: Principle #3: Rational People Think at the Margin.
Marginal changes are small, incremental adjustments to an existing plan of action.
№16 слайд
Содержание слайда: 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!
№17 слайд

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.

Содержание слайда: 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.
№19 слайд
Содержание слайда: Principle #6: Markets Are Usually a Good Way to Organize Economic Activity.
Adam Smith made the observation that households and firms interacting in markets act as if guided by an “invisible hand.”
Because households and firms look at prices when deciding what to buy and sell, they unknowingly take into account the social costs of their actions.
As a result, prices guide decision makers to reach outcomes that tend to maximize the welfare of society as a whole.
№20 слайд
Содержание слайда: Principle #7: Governments Can Sometimes Improve Market Outcomes.
Market failure occurs when the market fails to allocate resources efficiently.
When the market fails (breaks down) government can intervene to promote efficiency and equity.

an externality, which is the impact of one person or firm’s actions on the well-being of a bystander.
market power, which is the ability of a single person or firm to unduly influence market prices.
