Study Notes

Production Possibilities Frontier (PPF)

The PPF illustrates the boundary between attainable and unattainable combinations of goods and services.
Points inside the PPF represent attainable combinations.
Points outside the PPF represent unattainable combinations.
The PPF shows scarcity because it represents what cannot be produced given limited resources.

Production Efficiency

Production efficiency occurs when goods and services are produced at the lowest possible cost.
Points on the PPF represent production efficiency.
Points inside the PPF represent production inefficiency.
Choices made along the PPF involve tradeoffs with opportunity costs.

Opportunity Cost

The opportunity cost is the most highly valued alternative that must be forgone to get something.
Opportunity cost is a ratio.
An outward-bowed PPF reflects increasing opportunity cost.
Resources are not equally productive in all activities, leading to the outward-bowed shape of the PPF.

Allocative Efficiency

Allocative efficiency occurs when goods and services are produced at the lowest possible cost and in quantities that provide the greatest benefit.
Production efficiency is achieved at all points on the PPF.
Allocative efficiency is achieved when goods and services are produced at the greatest benefit, considering costs and benefits.

Marginal Cost

Marginal cost is the opportunity cost of producing one more unit of a good or service.
It represents the best alternative forgone.

Factors Influencing Demand

Price of related goods:
- Substitutes: The quantity demanded of a good is influenced by the price of its substitute.
- Complements: The quantity demanded of a good is influenced by the price of its complement.
Expected future prices: An expected increase in the future price of a good can lead to a higher current demand.
Income:
- Normal good: Demand increases as income increases.
- Inferior good: Demand decreases as income increases.
Expected future income and credit: Expected future income or credit can lead to an increase in demand.
Population: A larger population leads to a higher demand.
Preferences: Preferences determine the value people place on goods and services.

Change in Quantity Demanded vs. Change in Demand

Change in quantity demanded: This a change in buyers' plans as a result of a price change for the good while keeping other factors constant. It is depicted as a movement along the demand curve.
Change in demand: This occurs when a change in factors other than the price influences buying plans. It is represented by a shift of the demand curve.

Supply

Supply represents the relationship between the price of a good and the quantity producers plan to sell, keeping other factors constant.
Supply is described by a supply schedule and illustrated by a supply curve.

Quantity Supplied

Quantity supplied refers to a specific point on the supply curve, indicating the amount of a good producers plan to sell at a particular price.

Law of Supply

The Law of Supply states that, other things remaining the same, the higher the price of a good, the greater the quantity supplied.
A higher price increases quantity supplied due to rising marginal cost.

Factors Affecting Supply

Prices of factors of production: Changes in the prices of resources used to produce a good influence its supply.
Prices of related goods produced:
- Substitutes in production: Goods that can be produced using similar resources.
- Complements in production: Goods that must be produced together.
Expected future prices: Expected future price increases can lead to a decrease in current supply.
Number of suppliers: An increase in the number of suppliers leads to an increase in supply.
Technology: Technological advancements can increase efficiency and lower the cost of production, increasing supply.
State of nature: Natural events and environmental factors can influence production costs and thus supply.

Change in Quantity Supplied vs. Change in Supply

Change in quantity supplied: Occurs when the price of a good changes but all other influences on sellers' plans remain constant. It is represented by a movement along the supply curve.
Change in supply: Occurs when there is a change in a factor other than the price of the good, influencing sellers' plans. It is represented by a shift of the supply curve.

Equilibrium

Equilibrium price: The price at which the quantity demanded equals the quantity supplied.
Equilibrium quantity: The quantity bought and sold at the equilibrium price.

Adjustment to Equilibrium

Markets move towards equilibrium through price adjustments.
Price regulates buying and selling plans.
Price adjusts when plans don't match.

Price Elasticity of Demand

A units-free measure of the responsiveness of the quantity demanded of a good to a change in its price, keeping other factors constant.
