Q

What does a shortage do?

A
  • there will be a bidding war amongst onsumers to buy scarce goods
  • as P increases there will be some contraction of D
  • As P increases, this SIGNALS to entrepreneurs to produce more S

Q

Unitary elastic demand

A

When a change in price leads to equal proportional change in demand

Q

Substitution effect

A

When the price of a good falls, consumers will switch to buying this good, instead of buying the relatively more expensive alternate goods

Q

The rationing function

A

When the price rises because of a left shift in the supply curve, those who moderately enjoy the good will cease buying the good

Only those who really benefit from consuming the good will continue to buy the good at the higher price

Q

The signalling function

A

An increase in price, caused by a rise in demand, will signal to entrepreneurs to enter the market

A decrease in price, caused by a fall in demand, will signal to entrepreneurs to edit the marker

25
What are two reasons why the demand curve slopes downwards
The income effect - when price falls, people can afford to buy more The substitution effect - when price falls, people will substitute to buying that relatively cheap option
26
Extension of demand direction
Downwards
27
Contraction of demand direction
Upwards
28
What are factors that would increase the quantity demanded at any given price
- a rise in income - a fall in income tax - a rise in the price of substitute goods - a fall in the price of complementary goods - increased advertising - the good comes into fashion - population size increases - and increase in the quality of the good - less regulations on buying the good - speculative buying
29
What factors would increase the quantity supplies of a good at any given price?
- a fall in the cost of the raw materials - a fall in the cost of capital - a fall in the cost of labour - any other fall in the cost of inputs. E.g. rent - a technological breakthrough in the production process - subsidies increased or introduced - VAT is lowered - an improvement in the weather for agricultural goods - an increase in labour productivity, without an increase in wages - division of labour is introduced - De-regulation
30
If the supply curve shifts right,
The cost of production has fallen
31
Excess supply
Glut
32
Excess demand
Shortage
33
Why is the supply curve upward sloping?
Each unit of output is more difficult to produce than the previous unit
34
Lower triangle
Producer surplus
35
Higher triangle
Consumer surplus
36
The price elasticity of demand value
Measures the responsiveness of quantity demanded to change in price
37
The income elasticity of demand value
Measures the responsiveness of the quantity demanded to a change in income
38
The cross-price elasticity of demand value
Measures the responsiveness of the quantity demanded of Good A to change in the price of good B
39
The price elasticity of supply value
Measures the responsiveness of quantity supplied to a change in price
40
Elastic demand
When a change in price leads to a more than proportional change in quantity demanded
41
Inelastic demand
When ac change in price leads to a less than proportional change in quantity demanded
42
Unitary-elastic demand
When a change in price leads to an equal proportional change in quantity demanded
43
Inferior good
When income rises, quantity demanded decreases
44
Normal good
When income rises, quantity demanded increases
45
Normal good with income Inelastic demand
When a rise in income leads to a less than proportional increase in quantity demanded
46
Normal good with income elastic demand
When a rise in income leads to a more than proportional increase in quantity demanded
47
Substitute good / alternative good
When a price of one good rises, the quantity demanded of another good decreases
48
Complementary good
When the price of one good rises, the quantity demanded of another good decreases
49
Elastic supply
When a change in price leads to a more than proportional change in quantity supplied
50
Inelastic supply
When a change is price leads to a less than proportional change in quantity supplied
51
Total revenue formula
Total revenue = price x quantity sold TR = P x Q
52
% change formula
% change = new value - old value / old value x 100
53
Price elasticity of demand (PED) =
%change in QD / %change in P
54
Income elasticity of demand value (YED) =
%change in QD/ %change in income
55
Cross-price elasticity of demand value =
%change in QD of good A / %change in P of good B
56
Price elasticity of supply value =
%change in QS / %change in P
57
Elastic demand values (PED)
- infinity to -1
58
Inelastic demand values (PED)
-1 to 0
59
Inelastic supply values (PES)
0 to 1
60
Elastic supply values (PES)
1 to infinity
61
Inferior good YED values
- infinity to 0
62
Normal good YED values
0 to 1 ( and to infinity )
63
Luxury good YED values
1 to infinity
64
-0.6 cross-price elasticity of demand
Strong compliments
65
-0.2 cross-price elasticity of demand
Weak complements
66
0 cross-price elasticity of demand
Goods of no relation
67
+0.2 cross-price elasticity of demand
Weak substitutes
68
+ 0.6 cross-price elasticity of demand
Strong substitutes
69
PED
Price elasticity of demand
70
YED
Income elasticity of demand
71
XED
Cross price elasticity of demand
72
PES
Price elasticity of supply
73
Why would the PED be inelastic?
- Brand loyalty - a necessity - addictive - few close substitutes - forms a low percentage of income - peak-times for public transport
74
What factors cause PED to be elastic
- luxury, non-essential good - many close substitutes - weak brand loyalty - forms a high proportion of households income
75
The PED value changes along
A straight line
76
Lower part of P-Qd line
PED is inelastic
77
Midpoint of P-Qd line
Unitary elastic PED
78
High part of P-Qd line
Elastic PD
79
What factors make the PES value inelastic
- long production time - seasonal produce - volatile price - perishable - low stockpiles - the cost of storage is high - few available resources - firms operating at nearly full capacity - high legal barriers preventing new firms entering the market - high financial barriers preventing new firms entering the market
80
What factors cause the PED to be elastic?
- quick production time - production all year round - stable prices - non-perishable goods - cost of storage is low - large stockpiles - resources are easily available - few legal, marketing and financial barriers preventing new firms entering the market
