Change in Qd (formula)
% Change in Qd = ((Change in Qd)/(Initial Qd)) x 100
Change = Delta
initial Qd = quanity demanded at the initial (original) price
Note: Q1 is often used to denote the original quantity and Q2 the new quantity.
Price elasticity of demand (formula)
PED = (% Change in Qd) / (% Change in P)
Qd = demand P = Price
demand curve
The demand curve shows that the demand is higher when the price is lower and the demand is lower when the price is higher
law of demand
there is a negative relationship between price and quantity demanded
what ist Demand?
is the quantity of a good or service that buyers are willing and able to buy at a given price, in a given market, in a given period of time.
PED is equal to:
PED = (Delta Qd / Q1) x (P1 / Delta P)
What is it called when the PED coefficient is greater than one
price elastic
What is it called when the PED coefficient is smaller than one
price inelastic
What are the macroeconomic goals?
- sustainable economic growth • price stability (low inflation) • full employment (low unemployment) • balance of payments equilibrium • sustainable national debt (including low budget deficits) • more equitable distribution of income
Factors that Affect Price Elasticity of Demand
(1) the availability
of close substitutes,
(2) the proportion of income spent on the product/service,
(3) whether
the product/service is a luxury or necessity,
(4) time
examples of inelastic products
- petrol
- salt
- milk
When does a rise in price dont effect the amount of buyings?
When the proportion of income spent on a good is small
examples of luxury goods
- vacation
examples of necessity goods
- water
- bread
- mild
Is the demand for alcohol, cigarettes , and drugs tends are elastic or inelastic?
Inelastic, because there are linked to habit or addiction use.
income elasticity of demand (formula)
YED = (% Change in Demand) / (% Change in Income)
Income elasticity of demand (YED)
measures the percentage change in demand divided by the percentage change in income.
Is the elasticity coefficient for a normal good positive or nagativ?
always positive
Is demand and income related?
Yes, there are positive related.
superior goods
are luxury items that have an income elasticity of demand greater than one
What kind of goods have a negative income of elasticity of demand
inferior goods
Cross price elasticity of demand (XED)
measures how much the demand for one product/ service changes when the price of another product/ service changes.
cross price elasticity of demand (formula)
XED(AB) = (% Change in Demand for Good A) / (% Change in Price of Good B)
What does it mean when the cross price elasticity of demand coefficient is positive or neagtive number?
negative: Then the two goods are substitutes
positive: then the two goods are complementary
