get them to consume more
141
what is the point Qfm?
free market
no government intervention
142

a good that would be under consumed in a free market, as individuals do not fully perceive the benefits obtained from consumption
ought to be subsidised or provided free at the point of use and funded by the government
143
what externalities do merit goods genergate?
positive
144
what does society value and judge about merit goods?
that everyone should have them regardless of whether an individual wants them
social benefits exceed private benefits
145
what are demerit goods?

147
analysis paragraph:
how could the government intervene with a good with a negative externality?
- indirect tax on producers
- draw diagram + explain
- this would increase cost of production
- firms would internalise the external cost of the good shifting supply left
- prices would rise
- consumers would ration their consumption
- consumption would fall to Qso
148
evaluation paragraph:
evaluate the effectiveness of taxes on cigarette consumption
- depends upon the PED
- cigarettes - likely inelastic for addicted smokers
- rise in price leads to a less than proportional fall in consumption
149
evaluate the effectiveness of taxes

on a graph, the Y axis reads
P1
P
P2
what area is payed by the consumer?

complete the sentence:
another way the government can intervene in the cigarette market is by...
closing the information gap
using advertising to get us to consume less of a good
166
evaluate advertising

the government can also issue...
regulation and laws eg bans
to legislate the market

evaluate government intervention of regulation and legislation
- costly to police and implement
- black market
-opportunity cost
- legislation is only effective if there are consequences eg fines and must be likely and substantial
170
what is government failure?
when government intervention to correct market failure does not improve the allocation of resources or leads to the to a worsening of the situation
171
what are the reasons for government failure?
- imperfect information
- conflicting objectives
- administrative costs
- unintended consequences
172
explain how imperfect information causes government failure?
- eg for taxes and subsidies govt has to calculate externalities
- amount of MEC and MEB
- regulations
- govt provisions of goods and services
^^^^ all depends on adequate information
173
explain how conflicting objectives causes government failure?

spread out more
240

241
on a graph, what side of Q productive efficiency is diseconomies of scale?
right
242
on a graph, what side of Q productive efficiency is economies of scale?
left
243
on a graph showing external economies of scale, if you were to draw the point Q, what would that represent?
- at the same output, costs have fallen
- the firm is not producing more or less
- its a result of the market / industry
244
define diseconomies of scale
as the scale of production of a firm increases beyond productive efficiency, long run average costs rise
245
what assumptions are made surrounding economies of scale?
- the firm operates in the short run
- all firms are rational
246
what does it mean for firms to be rational?
they aim to maximise profits
247
what kind of process is short run profit maximisation?
a two stage process
248
what is step one of short run profit maximisation?
using marginal curves to arrive at the profit maximising output
249
what is the simple profit maximising rule?
if profits are to be maximised, MR must be MC
250
what is step two of short run profit maximisation?
using average curves to measure the size of the profit
251
what is total revenue?
price x Q
= average revenue x Q
252
what is total profit?
average profit x Q
253
what are the causes of diseconomies of scale?
- communication
- control
- coordination
254
what firms wont have a 'U' shaped LRAC curve?
natural monopolies - extremely large firms
255
what is an example of natural monopoly?
national grid
256
describe a non 'U' shaped LRAC curve
the fixed costs are so large productive efficiency and diseconomies of scale wont be met
257
define the minimum efficient scale (MES)
the lowest output which the firm is able to produce at the minimum achievable LRAC
258
how does a high MES act as a barrier to entry?
- there is already an established firm in the market,
- a small firm will have fewer customers
- and so had to try harder to get MES
259
what does MES stand for?
minimum efficiency scale
260
complete the sentence :
natural monopolies ______ reach _______
never reach MES
261
on a returns to scale graph,
what is on the left side of constant returns to scale?
increasing returns to scale
262
on a returns to scale graph,
what is on the righ side of constant returns to scale?
decreasing returns to scale
263
define increasing returns to scale
where an increase in factor inputs leads to a more than proportional increase in output
264
define decreasing returns to scale
where an increase in factor inputs leads to a less than proportional increase in output
265
what is the difference between increasing returns to scale and economies of scale?
- economies of scale is about cost saving that arise from factor inputs
266
what does the cost curve envelope show?
diminishing returns in the short run and economies of scale in the long run
267
describe a cost curve envelope
- the red curves represent a different premisses
- the LRAC curve is made up of the points of productive efficiency of the SRAC curves
268
what is technological change otherwise known as?
dynamic efficiency
269
describe dynamic efficiency / technological change
- long run concept
- requires a supernormal profit
270
what are the terms technological change / dynamic efficiency used to describe
- the overall effect of invention or innovation
- and the diffusion or spread of technology in the economy
271
what are the effects of technological change on methods of production?
- a movement of job production towards batch and flow
- specialisation
- movement away from skilled labour (labour v capital intensive)
272
evaluate the effects of technological change on methods of production
: movement away from skilled labour (labour v capital intensive)
- skill and labour is still required
- the more mechanised factories - more skilled labour
273
what are the effects off technological change on the cost of production?
- may lower the variable cost of labour
- labour cost fall - AC fall
- in the short run AFC rise (buy machines)
- increases productivity - fall in AC
274
evaluate the effects of technological change on costs of production
: may lower the variable cost of labour
may be more skilled so cost more
275
evaluate the effects of technological change on costs of production
: in the short run AFC rise (buy machines)
- long run costs fall
- firms benefit from tech econ of scale
276
what is static efficiency?
stationary, still
277
what are the types of static efficiency?
- productive efficiency
- allocative efficiency
278
describe dynamic efficiency
- requires supernormal profit
- long run
279
what does dynamic efficiency lead to?
- the development of new products and processes
- that improve productive efficiency
280
what are the different types of efficiency?
- static
- dynamic
- X
281
define creative destruction
- capitalism evolving and renewing itself overtime
- through new technologies and innovations
- replacing older ones
282
revenue =
sales x price
283
total revenue =
output x price
284
average revenue =
revenue per unit
285
marginal revenue =
addition to the total revenue of selling another unit
286
what are the different types of profit?
- normal
- subnormal
- supernormal
287
define normal profit
- the minimum profit a firm must make to stay in business
- which is insufficient to attract new firms into the market
288
what would economists include when working out a firms normal profit?
opportunity costs
289
when does normal profit occur?
when AC = AR
290
what profit occurs when AC > AR?
subnormal
291
what profit occurs when AR > AC?
supernormal
292
define supernormal profits
profits over normal profit
293
in what ways can the government intervene in market failure?
- taxes and subsidies
- price control
- advertising
- legislation
- do nothing
294
what are indirect taxes?
- expenditure tax
- increases cost of production for a firm but can be passed on to consumers via higher prices
