Study Notes

The Cost of Something

The cost of something you want is what you give up to get it.
You must consider the opportunity cost when making a decision.
The opportunity cost is the best alternative you forgo when making a choice.
The opportunity cost of going to college is more than just tuition, books, and fees; it also includes the wages you would have earned if you had worked.
The opportunity cost of seeing a film is more than just the ticket price; it also includes the value of the time you spend in the theater.

Rational People Think at the Margin

Rational individuals strive to achieve their goals in a systematic and deliberate manner.
To do so, they compare the marginal costs and benefits of their actions.
Marginal cost is the cost of producing one more unit, while marginal benefit is the additional benefit received by consuming one more unit.

People Face Trade-offs

Society and individuals face trade-offs because resources are scarce.
To obtain something desirable, you must give up something else.

Trade Can Make Everyone Better Off

People benefit from trade because it allows them to specialize in their areas of expertise and exchange goods and services for others.
Trade enables a wider variety of goods and services to be consumed at lower costs.
Countries can benefit from trade, obtaining better prices for their exports and acquiring goods more cheaply from abroad.

Markets Are Usually a Good Way to Organize Economic Activity

A market is a group of buyers and sellers who interact.
Markets organize economic activity by determining what goods to produce, how to produce them, how much of each to produce, and who receives them.
The price system serves as a key mechanism for allocating resources and determining production and consumption patterns.

Governments Can Sometimes Improve Market Outcomes

One role of government is to promote efficiency by addressing market failures and ensuring a fair distribution of economic well-being.
Market failures occur when the market, left to its own devices, fails to allocate resources efficiently, such as in cases of externalities or market power.
Externalities arise when the production or consumption of a good affects bystanders, such as pollution.
Market power exists when a single buyer or seller has significant influence over the market price, such as in a monopoly.
Governments can use policy tools like taxes, subsidies, regulations, and social welfare programs to address market failures and promote equity.

Prices Rise When the Government Prints Too Much Money

Inflation refers to a general increase in the price level.
In the long run, inflation is almost always caused by excessive growth in the quantity of money, which decreases the value of money.
The faster the government prints money, the higher the inflation rate.

Society Faces a Short-Run Tradeoff Between Inflation and Unemployment

In the short term (one to two years), many economic policies push inflation and unemployment in opposite directions.
This known as the short-term Phillips Curve.
The extent of this relationship can vary due to other factors, but the tradeoff remains constant.
