What Determines Demand In Market Flashcards
Product market
Goods and services which the consumer derives utility from
Market
Where buyers and sellers come into contact for the purpose of exchange
Commodity market
Raw materials , minerals used in the production of goods and services
Labour market
Buying and selling of labour time for the production of goods and services
Demand
Quantity of a good/ service purchased at a given price over a given time period
Why does demand curve slope downwards from left to right? (2)
1) Substitution effect - when price of good falls it becomes cheaper relative to its substitutes and some consumers switch their purchases from more expensive substitutes to good in question
2) income effect - when price of good falls , real income of consumer might rise - purchasing power of consumers nominal income has increased and so more of good can be bought
Movement along demand curve
Only when there is change in price
1) fall- extension of demand
2) rise- contraction in demand
Shits in demand curve
1) Fall in price of complementary goods
2) rise in price of substitutes
3) change in fashion and tastes which make the good more popular
4) increased advertising
5) increase in real income
6) decrease in income tax - increases disposable income and makes good more affordable
7) increase in population or change in age structure
8) increases in credit facilities which make it easier to obtain funds
Price elasticity of demand
Responsiveness of demand to a change in price
PED= % change in Q demanded of good A / % change in P of good A
If PED is greater than 1
Good is price elastic - % change in demand is greater than % change in price
If PED is less than one
Good is price inelastic - % change in demand is less than % change in price
PED = 0
Good is perfectly inelastic - % in price has no effect on Q demanded
(Drugs)
PED infinite
Good perfectly elastic - rise in price caused demand to fall to zero - demand curve = horizontal
Total revenue
Total payments firm receives from selling given quantity of goods / services
Price per unit multiplied by quantity sold
How would total revenue increase
Total revenue will increase as long as price is moving towards the mid- position of the demand curve ( where there sins unit elasticity)
IF DEMAND IS ELASTIC- cut in price increases total consumer spending and hence revenue to firm BUT rise in price causes total consumer spending to fall and so from loose revenue
IF DEMAND IS INELASTIC - increase in price increases total consumer spending and hence the revenue to firm BUT fall in prices causes total consumer spending to fall and so firms loose revenue
