Supply
The amount of a good or service a firm wants to sell, and is able to sell per unit time.
-Ability/willingness of the seller to make the stuff available for sale
Demand
The amount of a good or service a consumer wants to buy, and is able to buy per unit time
- Ability/willingness of the consumer to buy something
- As price increases, quantity demand increases
Supply curve
- Shows the The quantity supplied a each price, holding constant all other determinants of supply
- Dependent variable is the quantity supply
- Independent variable is the good’s price per unit
Demand curve
-Shows the demand of each price, holding constant all other determinants of demand
The DEPENDENT variable is the quantity demanded
• The INDEPENDENT variable is the good’s price per unit
Positive change in supply: what does it look like and why is it caused
- Shift to the right
- Weather
- Prices of factors of production
- Changes in production efficiency
Negative change in supply: what does it look like and why is it caused
- Shift to the left
- Weather
- Prices of factors of production
- Changes in production efficency
Positive change in demand: what does it look like and why is it caused
- Consumer income increases (shift to the right)
- Consumer tastes
- Availability of substitutes (decreases)
Negative change in demand: what does it look like and why is it caused
- Consumer income decreases (down)
- Consumer tastes
- Availability of substitutes (increases)
Changes in consumer income
Normal good and inferior good
Normal good vs inferior good
Normal
-When an increase in income causes and increase in demand. EX: organic food, coffee
Inferior
-When an increase in income causes a decrease in demand
EX: Maruchan, potatoes
What is a substitute and what makes two things substitutes
-Alternatives
-An increase in the price of one of them causes an increase in demand for the other
EX: An increase in the price of Nike Shoes would increase the demand for Adidas Shoes (assuming
they are substitutes)
What makes two things compliments
-An increase in the price of one of them causes a decrease in the demand for the other
EX: Thus, an increase in the price of bread would decrease the demand for eating peanut butter
(assuming they are compliments)
Equilibrium pt
Where supply and demand are equal
-AKA market price
Needs vs wants
Needs: basic to survival
Wants: Add to the quality of life
Goods
Things you can see and touch.
-Tangible products
Services
Wants satisfied through the efforts of other people or through the use of equipment.
Types of resources
- Natural
- Human (labor)
- Capital
Natural resources
All of the materials that come from earth, the water, or the air.
Human resources
- AKA labor
- The people who work to produce goods and services
Capital resources
The tools, equipment, and buildings that are needed to
produce goods and service. This includes the money needed to run firms.
Scarcity
- Situation in which consumer wants are greater than the resources available
- Lack of resources
- Consumer wants are greater than supply
Key economic questions
-WHAT to goods and services are to be produced
HOW should the goods and services be produced
-What needs and wants will be satisfied with goods and services being produced
(FOR WHOM?)
Surplus
Excess goods and services that cannot be sold because the price was too high
- More than enough product to meet the demand
- Top triangle
Shortage
Not enough goods and services available to meet demand because consumers are willing to pay more than current price.
- Not enough product to meed the demand
- Bottom triangle
