Demand basics~ 1.2.2 Flashcards
Define Demand?
The quantity of a good/service consumers are willing and able to buy at a given price in a given time period.
What does the law of demand state?
There is an inverse relationship between price and quantity demanded. As price increases, QD start decreasing and vice-versa assuming ceteris paribus
What is a contraction and extension in a Demand diagram
Contraction-when the point moves downwards
extension-when the point moves upwards
-this happens when it is caused by a price factor
Define ‘income effect’
When prices rise, income isn’t also going to rise so purchasing power remains the same consumers are less willing and able to buy
Define ‘substitution effect’
As prices of these goods and services will rise it will become more price-competitive, so consumers switch demand and consumption too buy other goods and services.
When demand shifts to the left or right, why does that happen?
This happens when it is a non-price factor.
what are the factors that involve demand to shift?
Population Advertising Substitute price Income Fashion Interest rate Complements price
How is population a determinant of demand shifting?
As the population rises, demand will rise and shift to the right and vice-versa.
How is Advertising a determinant of demand shifting?
Good advertising means demand will shift to the right and vice-versa.
How is income a determinant of demand shifting?
As income rises demand will rise so shift to the right. If income decrease the demand for normal goods will decrease and demand will shift to the right.
What is the effect of inferior goods as a determinant of demand?
Inferior goods will have the opposite effect so if incomes rise, demand will shift to the left but if incomes decrease then demand will shift to the right.
How is the interest rate a determinant of demand?
If interest rates become cheaper consumers are more willing to borrow so demand will shift to the right, but if interest rates become expensive consumers are less willing to borrow so demand will shift to the left.
