Q

Elasticity

A

a numerical measure of responsiveness of one variable following a change in another variable ceteris paribus

25
Elastic
where the relative change in the quantity demanded is greater than the change in price, income or the prices of substitutes and compliments
26
Inelastic
where the relative change in the quantity demanded is less than the change in price, income or the price of substitutes and complements
27
Price elasticity of demand (PED)
measures of the responsiveness of the quantity demanded for a product following a change in the price of the product,
28
Price elastic
when the relative change in the quantity demanded is greater than the change in price of the product
29
Price inelastic
when the relative change in quantity demanded is less than the change in price of the product
30
PED calculation
% change in quantity demanded / % change in price
31
Perfectly inelastic
where a change in price has no effect on the quantity demanded
32
Perfectly elastic
where all that is produces is sold at a given price
33
Unit elasticity
where the change in price is relatively the same as the change in quantity demanded
34
Income elasticity of demand (YED)
measures the responsiveness of the quantity demanded for a product following a change in income
35
Necessity good
a type of normal good with a YED that is close to 0
36
Superior good
a good with a YED greater than 1
37
Cross elasticity of demand (XED)
measures the responsiveness of the quantity demanded for one product following a change in the price of another product
38
YED calculation
%change in quantity demanded / % change in income
39
XED calculation
%change in quantity demanded of product A / % change in the price of product B
40
Price elasticity of supply (PES)
a numerical measure of the responsiveness of the quantity supplied to a change in the price of the product
41
Price elastic supply
the quantity supplied responds more than proportionately to a change in its price
42
Price inelastic supply
the quantity supplied responds less than proportionately to a change in its price.
43
PES calculation
%change in quantity supplied / % change in price
44
Equilibrium
where demand and supply are equal
45
Disequilibrium
a situation where demand and supply are not equal in the market
46
Equilibrium price
the price where demand and supply are equal,where the market clears
47
Equilibrium quantity
the amount that is traded at the equilibrium price
48
Changes in demand (or supply)
when there is a shift in the demand (supply) curve due to a change in factors other than the price of product
49
Excise duties
a specific tax that is levied on goods such as cigarettes
50
Ad valorem tax
a tax that is charged as a given percentage of the price
51
Derived demand
where the demand for a good or service depends upon the use that can be made from it
52
Joint supply
when two items are produces together
53
Rationing
where the producer limits the supply of products in the market to ensure the products remain exlusive
54
Signalling
where decisions taken by buyers or sellers are determined by the price
55
Transmission of preferences
the automatic way in which the market allows the wants of consumers to be made known to producers
56
Incentive
Where low or high prices influence consumption and production encouraging buyers to consume and sellers to produce
57
Consumer surplus
the difference between the price a consumer is willing to pay for a product and its market price
58
Producer surplus
the difference between the price the producer is willing to accept and what is actually paid.
