A

when a firm operates at maximum average total cost producing the maximum possible output possible from its inputs, For the economy as a whole occurs when it is impossible to produce more of one good without producing less of another or you cant make one person bettor off without another becoming worse off

25
derived demand
when the demand for one good or service comes from the demand for another good or service
26
price elasticity of demand
the responsiveness of demand to a change in price
27
formula for PeD
%change in Qd/ %change in price
28
interpretation of PeD
if the number is above 1=price elastic if below 1= inelastic perfectly elastic=infinity (1= unitary)
29
Income Elasticity of Demand
responsiveness of demand to a change in income
30
YeD formula
%change in Qd/%change in income
31
interpretation of YeD
-ive= inferior +ive=normal
32
opportunity cost
the next best alternative forgone when an economic decision is made
33
cross price elasticity of demand
the responsiveness of demand of one good to a change in price of another good
34
XpeD formula
%change in Qd of good a/ %change in price of good b
35
interpretation of XpeD
-ive=complementary +ive=substitutes between 1 and -1 inelastic
36
determinants of supply
change in production costs, change in wages, change in indirect taxes, change in technology, subsidies, change in productivity, expectation of future prices, number of sellers in the market, firms objectives, joint supply, regulation +bureaucracy
37
joint supply
when one good is produced another good is also produced from the same raw materials
38
price elasticity of supply
responsiveness of supply to a change in price
39
PeS formula
%change in Qs/ %change in price
40
factors affecting PeS
time, extraction+processing raw materials, availability of stocks/stockpiling, ease of switching between methods of production, availability of spare capacity, number of firms in the market, ease with which firms can enter the market, ability to alter production methods
41
equilibrium
the price at which demand equals supply and there is no tendency for change
42
disequilibrium
the price at which supply doesn't equal demand and there is likely to be a further change or reaction by buyers or sellers
43
excess supply
when qs at a particular price is greater than qd
44
excess demand
when qd at a particular price is greater than qs
45
minimum price
a price floor beneath which price is no allowed to fall
46
commodity
unbranded, homogeneous good (usually a raw materials or semi manufactured) bought and traded in bulk
47
factor markets
commodity needed to make a good
48
production
process that converts input into outputs of goods and services
49
labor productivity
measures output per worker or hour worked
50
fixed cost
doesn't vary with output (in short term)
51
variable cost
varies with output
52
labour productivity
total output per time period/ units of labour
53
economies of scale
as the scale of production of a firm increases long run average costs fall
54
internal economies of scale
cost saving resulting in the growth of the firm itself
55
external economies of scale
cost saving resulting in the growth of the industry
56
examples of internal economies of scale
R+D, financial, managerial, marketing ,bulk buying, technical
57
examples external economies of scale
technology, R+D , education , infrastructure
58
diseconomies of scale
as the scale of production of a firm increases long run average cost rises
59
examples of diseconomies of scale
int- failure of - communication, control, coordination, cooperation external- pollution
60
point at which LRAC is lowest is all known as
proactive efficiency
61
for what kind of firm will LRAC never rise
monopolies/ natural monopolies e.g. national grid
62
short run
at least one factor of production is fixed usually land
63
long run
all factors of production are variable
64
total revenue
price x units sold
65
average revenue
total revenue / no. sold = price
66
a firms demand curve also shows
its average revenue
67
market structures from most to least competitive and least to most concentrated
perfect competition, monopolistic competition, oligopoly, monopoly
68
features of a perfectly competitive market
perfect information, firm is a price taker, homogenous good, many small firms, low barriers to entry, consumer sovereignty, ability to buy and sell as much as you want at the ruling market price, factors of production are perfectly mobile
69
features of a monopoly
imperfect/asymmetric info, firm has full control over price, one large firm, high barriers to entry , producer sovereignty
70
factors used to determine market structure
numer of firms, product differentiation, barriers to entry, extent to which knowledge is perfect, influence of firms on price
71
CSR
corporate social responsibilities
72
objectives of firms
profit maximisation short/long run , sales maximisation, market share maximisation, survival, quality CSR
73
we assume that firms are
short run profit maximisers
74
division of labour
breaking down the production process down in to a sequence of tasks with workers assigned to particular tasks
75
benefits of specialisation of labour
workers become specialised, increases productivity, wage costs fall, greater output, allows for specialist machinery
76
specialisation
a worker preforming one task or a series of narrow tasks, also different firms specialising in producing particular goods or services
77
consumer sovereignty
through exercising their spending power consumers collectively determine what is produced in a market
78
producer sovereignty
producers or firms in a market decided what is produced and what is charged
79
pure monopoly
one firms, price setter ,complete barriers to entry
80
monopoly power
ability to dictate prices, high barriers to entry, big firm
81
factors which influence monopoly power
number of competitors, market share of the incumbent (the largest firm) concentration ratio, branding/advertising, barriers to entry, degree of product differentiation
82
barriers to entry natural vs artificial
nat- start up costs, economies of scale artificial- patents, predatory pricing
83
concentration ratio
a ratio which indicates the total market share of a number of leading firms in a market or the total output of these firms as a percentage of total market output
84
problems with monopolies
restrict supply -> proactively and allocative inefficient higher prices, reducer consumer welfare, lack of chow, exploit customer
85
benefits of monopolies
R+D economies of scale internationally competitive
86
Why competition is desirable
``` Lower prices More choices Greater efficiency Better quality Invention and innovation Consumer surplus ```
87
Market failure
Occurs when the free market fails to deliver an efficient allocation of resources Leads to over/under production/consumption
88
Missing market
A situation in which there is no market because the functions of price have broken down. This is a complete market failure
89
Causes of market failure
``` Externalities Merit and demerit good Public gooods Monopoly Inequality in distribution of income and wealth Factor immobility Imperfect information ```
90
Public good
Good that is non excludable, non rejectable and non rival
91
State provision
Gets around the problem of free riders in public goods
92
Externality
Cost or benefit that spill over to third parties outside the market transaction
93
Indirect tax
A tax on spending
94
Incidence of tax
The proportion of tax that is passed into the consumer
95
Merit good
Good with positive externalities. Will generally be under consumed in the free market
96
Demerit good
Good with negative externalities. Will generally be over consumed in a free market
97
Occupational immobility
As patterns of demand and employment change workers find it hard to get new jobs as they lack the necessary skills
98
Geographical immobility
Workers find ur difficult to move to areas with employment opportunities due to familial ties and housing costs
99
Policies to deal with income / wealth inequality
Income tax, free school meals, mandatory schooling, inheritance tax, benefits, subsidised childcare, bursaries, free healthcare
100
Consumer surplus
Difference between equilibrium price and price the consumer is willing to pay. Larger the surplus the greater the welfare
