Demand
The ability and willingness to buy a quantity of a good and service at a certain price in a given time period.
Law of Demand
As the price of the good falls, the quantity demanded will usually increase, ceteris paribus.
The income effect
When prices drop, concumers will have an increase in their real income, therefore the people will be likely to buy more of the product.
Subsitution effect
When the price falls, then the product will be relatively more attractivr than other products, whose prices have stayed unchanged, concuming more of the product, substituting it for products that were previously purchaced.
Shift in the demand Curve
Something besides price has changed causing the demand curve to shift out or inwards, these include non-price determinents.
Non-price Determinents
- Concumer Taste
- Number of buyers (size and structure of the population
- Price of Related Goods (Substitutes & Compliments)
- Comcumer Income (Normal good & Inferor good)
- Expectations
Complements
Products that are often pruchased together. Achange in the price of one product will lead to a change in the demand for the other product.
Normal goods
Goods that increase in demand when the income rises

Inferior goods
Goods that when the income rises the demand falls.
Exception to the Law of Demand
Velben goods (Branded/ Status goods)
As the price rises, the demand increases
Graph representing the relationship between the quantity demanded for velben goods and the price of the product.

Supply
The ability and willingness of producers to produce a quantity of a good and service at a given price in a given time period.

The Law of Supply
As the price of a product rises, the quantity supplied of the product will usually increase, ceteris paribus.
Movement along the supply curve
Due to a change in price
Shift along the supply curve
Due to non-price determinents of supply
Non-Price determinents of Supply
- Technology
- Prices of other products
- Resources
- Number of sellers
- Taxes&subsidies
- Expectations
Ceteris paribus
all other things being equal
Effective Demand
This is when concumers are willing and able to pruchace a good or service. It is when they have the financial means to buy the product, the ability to buy.
Substitutes
If products are substitutes from eachother, thena change in the price of the product, leads to a change in the demand for the other product. They are goods that can replace eachother.
Unrelated goods
A change in the price of one product will have no effect on the quantity demanded for the other product.
Linear Demand Function
Qd= a-bP
The relationship between the market demand of the product and the price of the product.
Linear Supply Function
Qs= c+dP
The relationship between the market supply of a product and the prices of the product.
