Policy Issues: resource taxes and climate change
Key concepts
•The
resources super profits tax
The resources super profits tax
•In
2010, the Rudd government announced a proposed Super
Profits Tax aimed
at raising $9 Billion annually.
•It
was highly unpopular in the minerals industry.
•A
‘watered-down’ version was brokered by Julia Gillard called the Minerals
Resource Rent Tax (MRRT).
Reasons for super profits tax
Policy implications
•Replacement
of the per-tonne royalty with super-profit tax would have resulted in:
–more
industry output
–fewer
firms exiting the industry when prices are low
–more
firms entering the industry when prices are high
Climate Change
Carbon emissions
•Carbon
Dioxide (CO2) emissions are:
–widely
argued to be the most important contributors to climate change
–the
main by-products of burning fossil fuel
•from
coal – fired power stations
•crude
oil transport
–Generated
by industries central to
the performance of modern economies.
Graphically incorporating Carbon
emission externalities
reducing market failure of
excessive carbon emissions
•Market
failure occurs when externalities exist from the market activities.
•Ways
of mitigating the market failure:
–carbon
tax
–regulation
–emissions
trading (ETS)
Carbon tax
•This
is where a per unit of carbon emitted tax is imposed on the polluting suppliers
–the
tax shifts the supply curve leftwards and thus the market price higher (with
reduced output) in an effort to reduce
the production of carbon emitting resources.
regulation
•Firms
would be forced to reduce their emissions in order to continue being in
business.
•Extra
costs, such as pollution control equipment would be incurred by the firm.
•These
costs shift the
supply curve leftwards and thus the market price higher (with reduced output) in an
effort to reduce the production of carbon emitting resources.
Emissions Trading (ETS)
•The
government announces the total allowable carbon emissions seen to be
appropriate for stabilising climate change.
•This
upper limit is known as ‘the cap’.
•This
gives the public an economic right to pollute as a society to a maximum level.
•This
level is split into permits which can be traded.
•Polluters
may purchase permits that allow them to emit the amount of carbon permitted by
the amount of permits they hold.
•These
permits can be purchased from firms that do not emit carbon pollutants, and
therefore can earn a return for ‘being green’.
Which policy is best
•Economists
prefer the policies in the following order:
1.ETS
2.Carbon
tax
3.Regulation.
Benefits of ETS and Carbon Tax
•ETS
encourages firms to treat clean air as a limited economic resource which they
must pay to use. The less they pollute they less permits they would require.
•The
carbon tax will discourage polluters from emitting, as they will be able to
maximise their profits by doing so.
Downside to regulation
•The
political agenda can interfere with the overall aim of reducing emissions.
•By
enforcing clean air alternatives there is an opportunity for interest-groups to
‘push’ their own energy source.
•Subsidies
paid to companies for clean air alternatives can be extremely costly to the
economy to install.
•These
outweigh the benefits of carbon reduction.
•Solar
panels, while clean, can cost much more than ETS permits which encourage
self-management.
