Study Notes

Economic Concepts

Economics studies how societies manage scarce resources and how economic agents (individuals, firms) interact.
Economic systems organize resource allocation (e.g., capitalist, planned).
Economic activity measures the volume of buying and selling.
Economic growth represents an increase in the amount of goods and services over time.
Market failure occurs when resources aren't allocated efficiently.
Externalities are costs/benefits imposed on third parties by economic decisions.
Standard of living is measured by wealth and the amounts of goods that can be purchased by a population in a country.
Productivity: amount of goods and services produced from each hour of a worker's time.

Supply and Demand

Quantity demanded decreases with price increase (Law of Demand).
Quantity supplied increases with price increase (Law of Supply).
Market equilibrium occurs where quantity demanded equals quantity supplied.
Surplus exists when quantity supplied exceeds quantity demanded (and price readjusts to equilibrium).
Shortage exists when quantity demanded exceeds quantity supplied (and price readjusts to equilibrium).
Demand curves show the relationship between quantity demanded and price.
Supply curves show the relationship between quantity supplied and price.
Individual demands and supplies, summed to market demand and market supply.

Elasticity

Price elasticity of demand measures how sensitive quantity demanded is to price changes.
Inelastic demand: Quantity demanded changes little with price changes.
Elastic demand: Quantity demanded changes significantly with price changes.
Perfectly inelastic demand: Quantity demanded does not change with price.
Perfectly elastic demand: Quantity demanded changes infinitely with small price changes.
Unit price elastic demand: Percentage change in quantity demanded equals percentage change in price.
Price elasticity of supply measures how sensitive quantity supplied is to price changes, similar to demand.

Consumer Theory

Utility: Satisfaction gained from consuming goods/services.
Indifference curves show combinations of goods/services providing the same level of satisfaction.
Budget constraint shows the combinations of goods/services consumers can afford.
Optimal consumption occurs when the highest attainable indifference curve touches the budget constraint, at the tangent point.
Substitution effect: Change in consumption due to a price change.
Income effect: Change in consumption due to the change in purchasing power resulting from a price change.
Giffen goods are inferior goods for which the quantity demanded increases as its price increases.

Production Theory

Production function shows the relationship between inputs and outputs.
Marginal product of an input is the increase in output resulting from an additional unit of that input.
Diminishing marginal product means the marginal product falls as more of the input is used.
Short-run costs involve fixed costs (don't change with output) and variable costs (change with output).
Long-run costs include all costs that vary with output.
Perfect competition means many buyers and sellers with homogeneous products, firms are price takers.
Profit maximization occurs where marginal revenue equals marginal cost.
The firm's short-run supply curve is the portion of the marginal cost curve that's above average variable cost.
In the long run, firms will remain only if price (P) covers average total cost (ATC).
Economies of scale exist when long-run average costs fall as output increases, whereas diseconomies of scale occur when costs increase with increased production.

Market Failure and Externalities

Market failures occur where markets fail to allocate resources efficiently.
Externalities are costs or benefits that affect third parties not directly involved in a transaction.
Negative externalities (e.g., pollution) result in overproduction, potentially corrected by taxes.
Positive externalities (e.g., education) result in underproduction, potentially corrected by subsidies.
The Coase theorem suggests that private bargaining can resolve externalities if transaction costs are low.
Deadweight loss is the fall in total surplus due to market inefficiencies.
Public goods are non-excludable and non-rival (e.g., national defense); markets often fail to provide them efficiently.
Common resources are rival but non-excludable (e.g., fish in the ocean), and overused by individuals without collective action.
Merit goods are underconsumed in a market (e.g., education)

Macroeconomics

Macroeconomics studies the economy as a whole.
Gross Domestic Product (GDP): Measures the total market value of final goods/services produced in a country during a specific period.
Components: Consumption (C), Investment (I), Government Purchases (G), Net Exports (NX).
Inflation measures the overall price level increase (e.g., CPI, GDP deflator).
Unemployment rate reflects the percentage of the labor force that's unemployed.
Aggregate demand shows total spending in an economy at various price levels.
Aggregate supply shows total output at various price levels.
Real GDP is the measure of output valued at constant prices.
Nominal GDP is the measure of output valued at current prices.
GDP per capita and GDP per worker are used to compare measures of national income.
Calculating real GDP from nominal GDP involves using the GDP deflator.
