Study Notes

Economic Activity

Buying and selling between households (consumers) and firms (producers) represents the level of economic activity.
The more buying and selling, the higher the level of economic activity.
Households provide land, labor, and capital to firms.
Firms use these factors to produce goods and services.

Scarcity

Scarcity refers to the limited nature of resources compared to unlimited wants and needs.

Economics

Economics is the study of how society manages its scarce resources.

Trade-offs

Making decisions involves choosing one option over others.
Trade-offs involve sacrificing benefits of the forgone option.
The decision to get one thing often necessitates giving up something else.

Efficiency and Equity

Efficiency focuses on maximizing output from scarce resources.
Equity examines the fair distribution of benefits among society's members.

Opportunity Cost

Opportunity cost represents the value of the best alternative forgone when making a choice.
It measures the benefits sacrificed when choosing one option over another.

Marginal Changes

Marginal changes are small incremental adjustments to existing plans.
Rational people make decisions by evaluating the costs and benefits of marginal changes.
Rational people aim to achieve their objectives optimally.

Incentives

Incentives motivate individuals to act, such as rewards or punishments.
People respond to incentives.

Benefits of Trade

Specialization and trade enable individuals and countries to produce more and consume more.

Market Organization

A market economy allocates resources through decentralized decisions of households and firms interacting in markets.
Markets determine what goods to produce, how much to produce, and who receives them.

Government Role

The government can improve market outcomes by providing goods and services not sufficiently supplied by the market.
Government intervention aims to promote efficiency and equity.

Market Failure

Market failure occurs when the market fails to allocate resources efficiently.
Examples of market failure include externalities (uncompensated impacts on third parties) and market power (undue influence on prices).
Public policy can enhance economic efficiency in cases of market failure.

Standard of Living

A country's standard of living depends on its ability to produce goods and services.

Productivity

Productivity measures the amount of goods and services produced per unit of labor.

Inflation

Inflation is a general increase in prices, caused by rapid and excessive money supply growth.

Perfect Competition

Perfect Competition: Many buyers and sellers, homogenous products, no individual influence over price.

Other Competition Types

Monopoly: One seller controls the market, influencing prices.
Monopolistic Competition: Many sellers offer slightly differentiated products.
Oligopoly: Few sellers, potential for limited competition.

Demand

Quantity Demanded: Amount buyers are willing and able to purchase at different prices.
Law of Demand: As price increases, quantity demanded decreases.

Demand Schedule and Curve

Demand Schedule: Table showing the relationship between price and quantity demanded.
Demand Curve: Graph depicting the relationship between price and quantity demanded.

Factors Affecting Demand

Price Changes: Movement along the demand curve.
Shifts in Demand: Changes in factors other than price.
Income Effect: Change in purchasing power with price changes.
Substitution Effect: Consumers switch to alternatives when prices rise.
Substitutes: Goods with a negative relationship in demand (e.g., milk and fruit juice).
Complements: Goods with a positive relationship in demand (e.g., milk and cereal).
Income: Changes in income affect demand.
Normal Goods: Demand increases with higher income.
Inferior Goods: Demand increases with lower income.
Tastes and Number of Buyers: Influencing demand.

Supply

Quantity Supplied: Amount sellers are willing and able to sell at different prices.
Law of Supply: As price increases, quantity supplied increases.

Supply Schedule and Curve

Supply Schedule: Table showing the relationship between price and quantity supplied.
Supply Curve: Graph depicting the relationship between price and quantity supplied.

Factors Affecting Supply

Price Changes: Movement along the supply curve.
Shifts in Supply: Changes in factors other than price.
Input Prices: Cost of production inputs influences supply.
Technology: Improved technology increases productivity and supply.
Natural/Social Factors: Weather, regulations, etc., affect supply.
Expectations: Producer forecasts of future prices influence supply.
Number of Sellers: More sellers lead to increased supply.

Utility Theory

Indifference Curves: Represent combinations of goods that yield equal satisfaction.
Marginal Rate of Substitution (MRS): The rate at which a consumer is willing to trade one good for another while maintaining utility.
Total Utility: Overall satisfaction from consuming a product.
Marginal Utility: Additional satisfaction from consuming one more unit of a good.
Diminishing Marginal Utility: Decline in additional satisfaction with increased consumption.

Utility Function

A utility function measures the satisfaction derived from consuming different combinations of goods.
The MRS is the ratio of marginal utilities.
