What is CONSUMER SOVIERNITY?
Where in a market system, consumers ultimately determine which goods/services will be produced.
What is a DEMAND SCHEDULE?
A table that shows the relationship between PRICE and QUANTITY
What is a DEMAND CURVE?
A graph / curve that shows the relationship between PRICE and QUANTITY
What direction does DEMAND CURVE have? Why?
Downwards slope, from top left to bottom right.
Because consumers will buy more when price low
What is QUANTITY DEMANDED?
The amount of a good/service that a consumer is willing and able to purchase at a given price.
What is MARKET DEMAND?
The demand by all consumers for a given good/service.
Illustrated by the Demand Curve
What is LAW OF DEMAND?
Holding everything else constant, when PRICE FALLS the QUANTITY DEMANDED INCREASES and vice versa.
What is the only focus when constructing a DEMAND CURVE?
The effect that PRICE CHANGES have on QUANTITY that a consumer is willing and able to purchase - all other variables held constant
What does CETERIS PARIBUS mean?
All being equal - it is the req’ment that when analysing the relationship between two variables other variables must be held constant
What is the SUBSITUTION EFFECT?
The change in the quantity demanded of a product that results from a change in price that makes the produce more/les expensive relative to substitute product.
Change in price of substitute product causes consumers to purchase more/less of a product.
What is the INCOME EFFECT?
The change in the quantity demanded of a product that results from the effect of a change in price on consumer purchasing power?
What is PURCHASING POWER?
The quantity demanded of products that can be bought with a fixed amount of income.
What happens to PURCHASING POWER when price of good falls?
Purchasing power increases - consumers willing / able to purchases a larger quantity.
What happens if other variable (NOT price) changes?
Consumers change the quantity they demand at every price.
Demand curve shifts left/right
If demand increases due to a variable other than price, does the demand curve shift left or right?
INCREASE = RIGHT
If demand deceases due to a variable other than price, does the demand curve shift left or right?
DECREASE = LEFT
What variables (other than price) affect market demand?
Income Price of related goods Tastes Population/Demographics Expected Future Prices
Why does INCOME affect market demand?
Cos it affects consumers’ willingness and ability to buy a good
What is a NORMAL GOOD?
Most goods!
… demand increases following an increase in income
… demand decreases following a decrease in income
but demand for some goods fall when income rises
What is an INFERIOR GOOD?
… demand increases following a decrease in income
… demand decreases following an increase in income
Why does the PRICE OF RELATED GOODS affect market demand?
Cos the price of other goods can also affect consumers’ demand for a product.
What are SUBSTITUTES?
Goods/services that can be used for the same/similar purpose
What happens to the demand curve when the price of a substitute decreases?
Demand for (first) good shift left.
What happens to the demand curve when the price of a substitute increases?
Demand for (first) good shift right.
