The document discusses various types of economic efficiency, including productive, allocative, and dynamic efficiency, emphasizing how optimal use of scarce resources can satisfy consumer needs. It highlights key concepts like Pareto efficiency, market equilibrium, and the impact of monopolies on welfare and consumer surplus. Additionally, it explores innovation's role in reshaping markets and addresses market failures that can arise from inefficiencies.

Topic 3.3.5
Students should be able to:
• Understand and distinguish between productive and
allocative efficiency
• Know that the minimum point on the average total cost is
the most productively efficient point and that allocative
efficiency occurs where price is equal to marginal cost
• Understand the meaning of inefficiency e.g. X-inefficiency

3. Google and Apple’s RevenueWhat is Economic Efficiency?
• Efficiency is about a society
making optimal use of scarce
resources to help satisfy
changing wants & needs
• There are several meanings of
efficiency but they all link to
how well a market system
allocates our scarce resources to
satisfy consumers
• Normally the market mechanism
is good at allocating these
inputs, but there are occasions
when the market can fail
How well are our scarce resources used? This is what is discussed
when economists talk about and analyse economic efficiency

Dynamic Social

Allocative efficiency is at
an output which
maximizes total consumer
welfare
At the market equilibrium
price, consumer and
producer surplus is
maximized – at this
output, economic welfare
is maximized.

5. Google and Apple’s RevenueBasics of Allocative Efficiency
• Allocative efficiency is reached
when no one can be made better
off without making someone
else worse off. This is also known
as Pareto efficiency
• Allocative efficiency occurs when
the value that consumers place
on a good or service (reflected in
the price they are willing and able
to pay) equals the cost of the
factor resources used up in
production.
• The main condition required for
allocative efficiency in a given
market is that market price =
marginal cost of supply

All points that lie on the PPF are allocatively
efficient because we cannot produce more of
one product without affecting the amount of
all other products available.

6. Google and Apple’s RevenueBasics of Productive Efficiency
• Productive efficiency exists
when producers minimize the
wastage of resources
• Productive efficiency also
relates to when an economy is
on their production
possibility frontier
• An economy is productively
efficient if it can produce
more of one good only by
producing less of another.
A firm is productively efficient when it is operating at the lowest
point on its average cost curve i.e. unit costs have been minimised

7. Google and Apple’s RevenueBasics of Social Efficiency
• The socially efficient level of
output and/or consumption
occurs when marginal
social benefit (MSB) =
marginal social cost (MSC)
• The existence of negative
and positive externalities
means that the private level
of consumption or
production differs from
social optimum
• The free market price
mechanism does not always
take into account social
costs and benefits

8. Google and Apple’s RevenueBasics of Dynamic Efficiency
Innovation is putting a new idea or approach into action. Innovation
is 'the commercially successful exploitation of ideas'
• Product innovation
• Small-scale and frequent subtle
changes to the characteristics
and performance of a good or a
service
• Process innovation
• Changes to the way in which
production takes place or is
organised
• Changes in business models and
pricing strategies
• Innovation has demand and supply-
side effects in markets and the
economy as a whole
Austrian economist
Joseph Schumpeter
(pictured) coined the
term creative
destruction which
refers to the
upheaval of the
established order in
the pursuit of
innovation.

businesses often

firms with market

9. Examples of Dynamic Efficiency
• Dec 2015: Porsche to make electric sports car in €700m
project - aimed at challenging Tesla's dominance of the
battery-powered sports car market
• Dec 2015: Ford says it will invest $4.5bn (£3bn) to
expand its fleet of plug-in and hybrid electric vehicles,
and will start selling 13 new electric models by 2020.
• Nov 2015: Huawei reveals a new quick-charge battery
• Nov 2015: The doctor will text you now: Will mobile
devices change healthcare? – new app allows doctors to
process their patients electronically and remotely

10. Competition Policy in the News
• Dec 2015: Cloud storage providers to face investigation
by regulators - investigation is to be launched into
whether internet users are being charged unfairly when
they use internet cloud storage services
• Nov 2015: Shell-BG deal to win green light –
competition regulators in China and Australia likely to
support move to create Britain’s biggest company

11. Key Concepts – Innovation in Markets
Cost-reducing innovation
Cost reducing innovations causing an
outward shift in supply. They allow
businesses to enjoy higher profit
margins with a given level of demand
Creative destruction
First introduced economist Joseph
Schumpeter. It refers to the dynamic
effects of innovation – with new products
or business models, some jobs are lost
but new ones are created.

• Main case against a monopoly is
that it makes higher profits at the
expense of a loss of allocative
efficiency.
• The monopolist will seek to
extract a price from consumers
above the cost of resources used
in making the product.
• Higher prices mean that
consumers’ needs and wants are
not being satisfied, as the
product is being under-
consumed.
• Higher prices cause a loss of
consumer surplus & welfare and
will disproportionately affect
lower income families.

Market failure is when the price mechanism leads to an inefficient
allocation of resources and a deadweight loss of economic welfare

14. Key Concepts – Economic Efficiency
Allocative efficiency
Producing what is demanded by consumers at a
price that reflect the marginal cost of supply
Dynamic efficiency
Changes in the choice available in a market
together with the quality/performance of
products that we buy.
Pareto optimality
Where it is not possible for individuals,
households, or firms to bargain or trade in such a
way that everyone is at least as well off as they
were before and at least one person is better off
Productive efficiency
Producing an output at the lowest feasible
average cost. This is at an output where AC=MC
X-inefficiency
A lack of real competition may give a monopolist
less of an incentive to invest in new ideas or
consider consumer welfare
