25
Name 4 factors that affect supply
1. Cost of Production 2. Availability of Resources 3. Advancements in Technology 4. Number of Suppliers 5. Indirect Taxes 6. Subsides 7. The Prices of Other Goods
26
Describe how the cost of production affects supply
Increase in cost of production (e.g. Raw materials, wages) = decrease producers' profits (supply curve to shift to the left)
27
Describe how the availability of resources affects supply
Availability of resources increase = can create more products (= supply curve will shift to the right)
28
Describe how advancements in technology affects supply
Advancements (or improvements) in technology will increase supply as they reduce the cost of production
29
Describe how the number of suppliers affects supply
Increase in number of suppliers in a market = increase supply to the market (= supply curve shifts to the right)
30
Describe how subsides affect supply
If producer receives a subsidy = supply will increase because costs are reduced
31
Describe how indirect taxes affect supply
When they imposed/increases = supply will fall because indirect taxes represent a cost to firms
32
Describe how the prices of other goods affect supply
Firms may switch production to workable alternatives if its price starts to rise = supply of alternative product will increase while supply of existing product will fall
33
Why does the supply curve slopes UPWARDS?
Direct relationship between price and quantity
34
Illustrate a change in price on a supply curve
35
Illustrate a shift in supply on a supply curve
36
What is market equilibrium?
Where quantity demanded EQUALS quantity supplied
37
What is equilibrium price?
Price of a good or service when supply is equal to demand
38
What is equilibrium quantity?
Quantity demanded and supplied at the equilibrium price
39
What is excess demand?
When price DECREASES and consumers demand more and producers supply less aka shortage
40
Illustrate excess demand
41
What is excess supply?
When price INCREASES and producers supply more and consumers demand less aka surplus
42
Illustrate excess supply
43
What is price elasticity of demand?
The responsiveness of demand to a change in price
44
How do you calculate PED?
Percentage Change in Demand --------------------------------------------------- Percentage Change in Price
45
If PED is more than 1, it's...
Elastic
46
If PED is less than 1, it's...
Inelastic
47
If PED is exactly 1, it's...
Unit Elastic
48
If PED is exactly 0, it's...
Perfectly Inelastic
49
PED: Illustrate Unit Elastic
Can be a straight line
50
PED: Illustrate Perfectly Inelastic
51
PED: Illustrate inelastic demand
52
PED: Illustrate elastic demand
53
What is meant if the demand for product is price elastic?
Change in demand will be greater than change in price
54
What is meant if the demand for product is price inelastic?
Change in price will be greater than change in demand
55
PED: Name 4 factors of price elastic goods
* Many close substitutes * Non-essential good * Product widely available * Large proportion of income
56
PED: Name 4 factors of price inelastic goods
* Habit forming * Essential good * Few substitutes * Small proportion of income
57
What is price elasticity of supply?
Responsiveness of supply to a change in price
58
How do you calculate PES?
Percentage Change in Supply --------------------------------------------------- Percentage Change in Price
59
Name 4 factors that determine PES
* Time (Production Speed) * Spare Capacity * Availability of Factors * Stocks
60
Describe how time (production speed) affects PES
If a company has little time to increase supply = the supply will be INELASTIC
61
Describe how spare capacity affects PES
If a company is not using all their resources = supply can increase quickly (ELASTIC)
62
Describe how the availability of factors affects PES
If a firm can easily access the factors of production = changes in supply will be ELASTIC
63
Describe how stocks affects PES
If a company has spare stocks = supply can increase quickly (ELASTIC)
64
PES: Illustrate price inelastic
65
PES: Illustrate price elastic
66
What is income elasticity of demand (YED)?
Responsiveness of demand to a change in INCOME
67
Describe how to calculate YED
Percentage Change in Demand --------------------------------------------------- Percentage Change in Income
68
Describe how normal goods affects YED
As income increases, demand for these goods increase
69
Describe how inferior goods affects YED
As income increases, demand for these goods decreases
70
Normal goods = _______ YED
POSITIVE
71
Inferior goods = ______ YED
NEGATIVE
72
Interpreting YED: What happens if it's greater than 1?
* Elastic * Normal Good
73
Interpreting YED: What happens if it's less than -1?
74
Interpreting YED: What happens if it's between 0 and 1?
* Inelastic * Normal good
75
Interpreting YED: What happens if it's between -1 and 0?
* Inelastic * Inferior good
76
Interpreting YED: 0 Decimal (e.g 0.65) = \_\_\_\_
Inelastic
77
What is total revenue?
Total income earned by the business
78
How do you calculate total revenue?
TR = Price × Quantity Demanded
79
What happens to price & TR if a good is elastic?
Price Increases, TR decreases Price decreases, TR increases {Opposites - Price & TR}
80
What happens to price & TR if a good is inelastic?
Price increases, TR increases Price decreases, TR decreases {Same - Price and TR}
81
How does the government use price elasticity?
* They impose indirect taxes on goods with are price inelastic * Because consumers cannot easily avoid buying them
82
What is specialisation?
Producing one product in great detail
83
What is occupational specialisation?
When an individual is specialised in one specific job
84
What is factor substitution?
When technology takes over the job of a human workforce
85
Name 3 advantages of occupational specialisation
* More experienced and qualified * Job will be done efficiently * Higher salary
86
Name 3 disadvantages of occupational specialisation
* Job may become repetitive or boring * Job rotation is restricted * Responsibility is on one worker
