Study Notes

Demand and Supply Curves

Movement vs. Shift: Movement along curves occurs with price changes, while shifts indicate changes in demand/supply for reasons other than price.
Law of Demand: As price decreases, quantity demanded increases; as price increases, quantity demanded decreases, assuming ceteris paribus (all else constant).

Demand

Quantity Demanded: Amount consumers are willing to buy at a specific price.
Demand Schedule: A table correlating product price to quantity demanded.
Demand Curve: Graphical representation of price vs. quantity demanded.

Factors Shifting Demand

Income:
- Normal goods: Demand increases with income.
- Inferior goods: Demand increases as income falls.
Prices of Related Goods:
- Substitutes: Alternative goods that can replace one another.
- Complements: Products used together increase demand for each other.
Tastes and Preferences: Influenced by trends, seasons, and individual consumer preferences.
Population and Demographics: Demand typically rises with population growth. Changes in demographics impact specific market needs.
Expected Future Prices: Anticipation of price changes can prompt increased present purchases if prices are expected to rise.

Supply

Quantity Supplied: Amount that firms are willing to supply at a specific price.
Supply Schedule: Table showing the relationship between price and quantity supplied.
Supply Curve: Graphical depiction of price versus quantity supplied.

Factors Shifting Supply

Prices of Inputs: Costs related to production inputs influence supply.
Technological Change: Advances can increase supply efficiency.
Prices of Substitutes in Production: Changes can divert resources to more profitable goods.
Number of Firms: More firms generally increase total market supply.
Expected Future Prices: Anticipating changes can alter present supply strategies.

Market Equilibrium

Equilibrium occurs where quantity demanded equals quantity supplied.
Surpluses: Occur when supply exceeds demand, leading to downward pressure on prices.
Shortages: Occur when demand exceeds supply, leading to upward pressure on prices.
Supply Increase Impact: Leads to lower market prices and higher equilibrium quantity.
Demand Increase Impact: Results in higher market prices and increased equilibrium quantity.

Behavioral Economics

Focuses on choices that defy rational economic behavior.
Common consumer mistakes include not accounting for non-monetary opportunity costs and being overly optimistic about future actions.

Opportunity Costs

Opportunity Cost: The cost of the next best alternative forgone when a decision is made.
Endowment Effect: Consumers’ reluctance to sell owned items even when presented a higher selling price than their buying price.

Production Possibility Frontier (PPF)

Visual tool to demonstrate resource efficiency and the trade-offs in production.
Points inside the curve indicate inefficiency, while points on the curve represent efficient resource usage.
Scarcity: Limited resources must meet unlimited wants.
Absolute Advantage vs. Comparative Advantage: Absolute focuses on productivity measures; comparative based on lower opportunity costs.

Currency Impact on Production

A weaker currency generally enhances production competitiveness, while a stronger currency can reduce production efficiency.
