Price Determination in a Competitive Market Flashcards
Demand?
The quantity of goods and services that consumers and willing and able to buy at given prices in a particular period of time
Effective Demand?
consumers’ desire to buy a good, backed by an ability to pay
LAW OF DEMAND
- as price falls, quantity demanded rises
- inverse relationship
Extension in demand?
- increase in quantity demanded from a fall in price
Contraction in demand?
decrease in quantity demanded from a rise in price
Shifts of Demand curve?
1) real disposable income (incomes after effects of inflation, taxation and benefits)
2) Tastes and preferences
3) Population
4) Price of Substitutes
5) Price of Compliments
Substitutes?
goods that may be consumed as an alternative to another good (competitive demand)
Complimenta?
goods tend to be consumed with another good = joint demand
Price Elasticity of demand?
responsiveness of quantity demanded of a good or service to a change in price
PED Equation:
percentage change in quantity demanded/ percentage change in price
price INELASTIC demand
- value of PED between 0 and 1
- change in price leads to a smaller percentage change in quantity demanded
price ELASTIC demand
- value of PED > 1
- change in price leads to a larger percentage change in quantity demanded
unitary ELASTIC demand
- value of PED = 1
- change in change in price has led to the same percentage change in quantity demanded
perfectly INELASTIC demand
- value of PED = 0
- change in price has led to no change in quantity demanded
perfectly INELASTIC demand
- value of PED = infinity
- change in price has led to an infinitely larger change in quantity demanded
PED AND TR:
if demand is price INELASTIC (fall in price)
- fall in total revenue
PED AND TR:
if demand is price ELASTIC (fall in price)
- rise in total revenue
PED AND TR:
if demand is price INELASTIC (rise in price)
- rise in total revenue
PED AND TR:
if demand is price ELASTIC (rise in price)
- fall in total revenue
