Charges
Levies on users of transport services to recover the
cost of resources used. An access charge, for example, is a fee an operator
of transport services pays for the use of infrastructure. Economic theory
suggests that users should pay the full cost-private and social-of the
resources used. Taxes are levied over and above charges.
Competitive neutrality
Competitive neutrality exists when different transport
modes operate under similar or consistent investment, taxation, charging
and regulatory frameworks.
Economically efficient tax
A tax that is 'neutral' in its effect on decisions to
work, save and invest.(1) But since all taxes affect such decisions
to some extent, a goal of taxation policy is to minimise distortions in
behaviour. Other goals are to raise revenue, reallocate resources, and
improve equity.
Economically efficient prices
Prices that reflect the full cost, private and social,
of resources used.
Externalities
Externalities arise when one party imposes on
others costs or benefits which are not reflected in market transactions.
For example, 'negative' externalities such as noise and air pollution
from trucks impose costs on residents near highways, but there is no market
transaction between residents and the users of the truck services.(2)
Full cost
The total cost, private plus social, of providing a service.
Private costs, for example, include fuel, labour and depreciation. Private
costs are borne by the service provider and are reflected in user prices.
Social cost
The cost to society, over and above private costs, of
undertaking an activity. Examples of social costs are damage to roads
and externalities. Third parties usually incur social costs. Economic
theory suggests that transport users should compensate those who bear
social costs.
Major
Issues
Taxes and charges affect relative costs of using different
transport modes. If not applied consistently across modes, charges and
taxes can distort use in favour of one mode over another. The main charges
applying to rail and road transport are access/registration and safety
fees, while the main taxes are the diesel fuel excise, payroll tax, import
duty and company tax. The competitive neutrality of charges and taxes
on rail and road transport-has long been debated with each industry claiming
it is disadvantaged by particular charges or taxes.
The general principle on which transport charges and
taxes are based is that the service user should pay the full cost to society
of providing the service. Cost includes private cost such as petrol and
wages, and social costs such as damage to roads and externalities such
as noise, air pollution, congestion and accidents. But in practice, charges
and taxes diverge from economically efficient prices, which would reflect
the full cost of transport services. For example, in principle, transport
users should compensate those who bear the cost of externalities but this
rarely happens. Governments could impose taxes to reduce externalities
but there are no taxes on road or rail externalities in Australia.
Heavy trucks account for most damage to roads, and require
roads to be constructed to higher-and more costly-standards (for example,
relating to bridge strength and pavement characteristics) than otherwise.
Economic theory suggests that charges on heavy trucks should vary with
actual road usage. State governments impose charges to recover the cost
of the damage heavy vehicles cause. The charges have two components: a
fixed annual registration charge and a 'notional' part of the diesel fuel
excise. But the registration charge does not vary with distance travelled
and gives rise to cross subsidies; for example, lighter trucks cross-subsidise
heavier trucks. The appropriateness of the attribution of part of the
diesel fuel excise towards road use charges depends on whether the diesel
fuel excise is viewed as a general revenue-raising tax or whether is a
specific revenue-raising tax. If the excise is the former, road freight
is undercharged. Still, the diesel excise is a proxy for the cost of road
use in that the total amount of excise a user pay through fuel consumption
is related to distance travelled and vehicle weight, and hence damage
to roads.
Controlling for mass and distance, rail access charges
greatly exceed road user charges. This has led to claims that differentials
in access charges confer a competitive advantage to road transport. But
there is no reason that access charges should be the same for all modes.
It is not possible to determine whether State rail access charges reflect
social costs since the basis on which State rail authorities calculate
their charges is opaque.
The total social cost of transport externalities is considerable.
Moreover, the cost of road externalities is in the order of seven times
the cost of rail externalities for interstate non-bulk freight transport.
It is unlikely that the diesel fuel excise is intended to take account
of externalities. Even if it were, the excise would be too low in metropolitan
areas.
The imminent changes to the taxation system will affect
the relative competitiveness of rail and road transport. Studies of the
changes as originally proposed suggest that, overall, the restructuring
will deliver greater benefits to road than to rail transport mainly because
trucks use more fuel and thus benefit more from the proposed reduction
in the effective rate of excise on diesel from around 43 to 18 cents per
litre. But even after the tax changes are implemented, charges and taxes
will not be competitively neutral between road and rail. The main changes
needed to attain competitive neutrality are to impose charges on heavy
vehicles that more fully reflect the cost of their use of roads, and to
ensure that both rail and road face the full cost of externalities, with
road in particular having to pay more. Proposed changes to heavy vehicles
charges will help remedy the former. And had the full diesel fuel excise
rebate not been extended to rail, its competitive position relative to
road transport would have been worse. Even so, charges and taxes will
still not be competitively neutral.
Taxes and charges are only one aspect of government policies
affecting competitive neutrality between rail and road transport. Other
relevant policies include infrastructure investment appraisal and funding
arrangements,(3) access regimes, safety regulation, and operating
procedures and standards. Competitive neutrality of charges and taxes
alone would, therefore, still not resolve the issue of whether government
policies advantage or disadvantage one mode relative to the other.
Introduction
All transport modes-road, rail, air and sea-compete to
varying degrees. User choice of mode depends on a range of factors including
the characteristics of the goods and passengers to be transported, service
characteristics such as journey time and reliability, and service prices.
Governments levy charges on all modes to recover the cost of providing
infrastructure and other resources used in transport services, and impose
taxes to raise revenue, change the allocation of resources and for equity
reasons.(4) Charges and taxes affect prices of each mode and
hence their relative competitiveness. If not levied efficiently, charges
and taxes can distort use towards a particular mode, and so reduce the
economic efficiency of the transport system as a whole. Ultimately, national
productivity can be impaired.
The consequences of government charges and taxes on the
relative competitiveness of rail and road freight transport have long
been contentious.(5) The rail freight industry, for example,
claims that charges and taxes are not competitively neutral but advantage
road over rail.(6) The road freight industry, on the other
hand, claims that its inputs are more heavily taxed than other industries.(7)
To assess these claims, this paper reviews the economic principles on
which charges and taxes are based, and how charges and taxes are levied
in practice. In particular, it examines whether taxes and charges are
being applied consistently across both modes. The paper does not deal
with other policy areas-such as levels of infrastructure investment, access
regimes, safety regulation, and operating procedures and standards-which
also affect competition between the two modes.(8) Indeed, some
of these areas, particularly infrastructure investment, may be more important
than charges and taxes in trying to attain competitive neutrality.(9)
Principles of Efficient
Charging and Taxing
Economic theory suggests that users should pay the full
cost of providing transport services through charges and taxes.(10)
Thus prices of road transport services should reflect not only private
costs-such as fuel, wages and depreciation-but also social costs such
as damage to roads, environmental costs, and the social costs of road
accidents. Failure to reflect the cost of road damage in prices would
constitute a subsidy to road users from taxpayers, who pay for the construction
and maintenance of roads. The divergence of private from social costs
would be a misallocation of resources.
Economic theory suggests that transport users should
pay for the cost of negative externalities-such as noise, air pollution,
congestion and accidents-users impose on those adversely affected. This
could be achieved if transport users were to compensate those affected.
The cost of compensation would be reflected in user prices, and private
and social costs would be the same. Alternatively, governments may, in
principle, tax externalities to reduce their output to optimal levels.(11)
In practice, it is difficult to apply efficient pricing
principles to charges and taxes so that user prices incorporate social
as well as private costs. As a result, actual charges and taxes diverge
from economically efficient prices and give rise to inconsistencies. For
example, as discussed below, charges for heavy road vehicles only approximate
the actual cost of the damage such vehicles cause to roads. The absence
of mechanisms to compensate for the cost of externalities means that those
who bear the costs are generally not compensated.(12) And it
is difficult to calculate optimal levels of externalities and appropriate
taxation levels.(13)
Charges and Taxes on
Rail and Road Freight Transport
The former Bureau of Transport and Communications Economics
has classified the charges and taxes governments levy on transport into
five categories: charges for the use of infrastructure; fuel taxes; vehicle
charges and taxes; operations charges and taxes; and taxes on externalities.(14)
The main charges applying to rail and road transport are access/registration
and safety fees, while the main taxes are the diesel fuel excise, payroll
tax, import duty and company tax.(15) No taxes are levied on
transport externalities.
Road
As noted, efficient charging requires that users bear
the full cost to society of resource use including damage to roads and
externalities. Heavy trucks account for most damage to roads and the amount
of damage is related to vehicle weight, distance travelled, number of
axles and the strength and thickness of the pavement. Charges for road
damage should, therefore, be based on these factors.(16) State
governments impose heavy vehicle(17) road use charges to recover
the cost of road damage these vehicles cause. The National Road Transport
Commission (NRTC) is responsible for developing the charges. They have
two components: a fixed annual registration charge and a 'notional' part
of the diesel fuel excise.
Registration Charge
The amount of the registration charge depends on vehicle
class, the purpose for which the vehicle is used and the number of axles.
Charges for a particular class of vehicle are based on the average distance
travelled by that class and the average gross mass of that vehicle class.
Because the charge does not vary with distance travelled but is based
on averages, it gives rise to cross subsidies. Thus a truck that travels
long distances pays the same amount as an identical truck that travels
short distances, so that the latter cross-subsidises the former.
Another feature of the current registration charges is
that lighter trucks cross-subsidise heavier trucks because the charges
under-recover the cost of the damage large trucks cause.(18)
This has implications for competitive neutrality between rail and road.
The rail freight industry argues that it competes mainly with large trucks
that travel the longest distances and carry the heaviest loads, so that
the cost under-recovery for heavy trucks advantages road over rail freight.
The Productivity Commission concurs noting:
The existing road user charging system for heavy
vehicles underrecovers road costs attributable to classes of vehicles
that compete directly with railways. This confers a competitive advantage
on long distance road transport operators.(19)
The Bills referred to below seek to reduce the cross-subsidisation
of heavy trucks by lighter trucks by increasing the charges the former
pay.
A number of overseas jurisdictions employ weight-distance
charging including some States in the United States. The European Union
is moving towards scaling road charges so that they are commensurate to
kilometres travelled, energy consumed, use made of roads, and costs generated.(20)
In New Zealand, such charging has applied since 1978 (see Box 1).
|
Box 1: Road User Charging in New Zealand
The Road User Charges Act was introduced in New Zealand in 1977.
Since April 1978, most heavy vehicles have been required to pay
licence fees directly proportional to distance travelled. The fee
scale varies according to the type of vehicle, the number and spacing
of axles on the vehicle, and the number of tyres on the vehicle.
Vehicle classes are based on combinations of these characteristics.
For each class, the scale of the distance-related fee rises steeply
with increasing gross vehicle weight up to a threshold of 30 tonnes.
Above 30 tonnes, there are linear scales per tonne for all vehicles.
The distance licences are available in multiples of 1000 kilometres.
Road transport operators are required to identify the vehicle class,
nominate the maximum gross weight for which the vehicle is to be
licensed, and nominate the start and finishing kilometres. Licences
can be purchased at New Zealand Post Offices and are displayed on
vehicle windscreens. Hubodometers (which measure distance travelled)
are fitted to vehicles in the scheme. The kilometres recorded on
the hubodometer must not exceed the kilometres shown on the licence
purchased.
Exemptions and exclusions to the scheme include off-road vehicles
(which are required to have time-licences), trailers under 3.5 tonnes
gross laden weight (because of their relatively small contribution
to road costs) and petrol-powered vehicles with a gross weight of
3.5 tonnes or less. The last category are exempt because the excise
tax on petrol is assumed to produce a broadly equivalent charge.
Owners of petrol-powered vehicles exceeding 3.5 tonnes buy distance
licences but receive a rebate for the petrol tax paid.

Diesel Fuel Excise
As noted, the second component of heavy vehicle road
charges is a notional part of the diesel fuel excise. The charge has a
legislative basis. Schedule 1 of the National Road Transport Commission
Act 1991 defines road use charge as:
... a charge equal to the part of the diesel fuel
tax levied by the Commonwealth for the use of a Vehicle on a road
being the part fixed by the National Commission from time to time,
in accordance with this Agreement.
The notional amount is now 18 cents per litre. The NRTC
has proposed that the notional charge rise to 20 cents, and the Bills
introduced into Parliament on 8 March 2000 by the Minister for Transport
and Regional Services, the Hon. J Anderson, seek to give effect to the
NRTC's proposal.(21) The 20 cents that the NRTC proposes as
the revised notional charge is the same as the effective rate of diesel
fuel excise under the A New Tax System (ANTS) reforms.(22)
The appropriateness of the NRTC's attribution of part
of the diesel fuel excise towards road use charges depends on whether
the diesel fuel excise is seen as a general revenue-raising tax or as
a specific revenue-raising tax. (23)For if the excise is the
former, it could be argued that a cost recovery charge additional to the
diesel fuel excise should apply to road freight transport. In short, road
freight is undercharged. Moreover, if the excise is a specific tax, the
rail industry should not have to pay it since the industry is a not a
road user. As the Productivity Commission noted:
If the excise is considered to be a general-purpose
tax, heavy vehicle charges will require adjustment. Alternatively,
if it were considered to be a road usage charge (that is, a specific-purpose
tax), the excise would apply only to road users and heavy vehicles
would attract a rate of 18 cents a litre.(24)
The lack of clarity over the purpose of the diesel fuel
excise lies in its origins and subsequent decisions. When the excise was
introduced in 1957, the proceeds were earmarked (hypothecated) to spending
on roads. Because the excise was aimed at road users, off-road use was
exempt. Under the Diesel Fuel Rebate Scheme, eligible applicants can claim
a rebate of the excise on diesel used off-road.
But links between the amount of revenue raised by the
excise and road spending have become increasingly attenuated. The effective
discontinuation of hypothecation and the extension of the excise to include
non-road use in rail and sea transport suggest that the original purpose
of the excise has changed. Indeed, it can be argued that successive governments
have increasingly viewed diesel fuel excise as simply another form of
revenue. The Minister for Transport and Regional Services, the Hon. John
Anderson, considers fuel excise to be a source of general revenue:
While on the question of changes to fuel taxes, it
is important to point out that the Federal Government does not consider
diesel fuel excise to be a road user charge.
Fuel taxes and the revenue they generate have no
correlation to the amount of funds provided either to states or nationally
for roads. Fuel excise today is a source of general revenue, just
like income and other taxes.(25)
Whatever its purpose, in the absence of alternative mechanisms-such
as tolls-to charge for road use, the diesel excise is, nevertheless, a
proxy for the cost of road use in that the total amount of excise a user
pays is related to distance travelled and vehicle weight through fuel
consumption, and hence to wear and tear on roads.
Rail
Access Charges
As with road, the main issue is whether charges for access
to infrastructure reflect the cost to society of its use. (A brief outline
of how rail operators can gain access to rail facilities is in Box 2.)
Damage to rail infrastructure depends mainly on the type of track, train
weight and distance travelled.(26) The Australian Rail Track
Corporation-which was created after the Commonwealth and State governments
agreed in 1997 to form a 'one stop' shop for operators seeking access
to the national interstate rail network-imposes access charges. Operators
pay a two-part charge. The first element is a fixed component known as
the flagfall and is, in effect, a charge for occupying capacity on the
network regardless of the size of the train. The second charge is a mass
distance charge based on the gross tonnage of the train multiplied by
the distance travelled.
The access charges that State rail authorities levy differ
across jurisdictions and are complicated. The NSW access regime, for example,
has separate pricing principles for 'general usage' and coal freight.
General usage access prices are negotiated between 'floor' and 'ceiling'
prices. In the case of coal freight, on some routes the access price is
negotiated as for general usage while on others, the access price is an
adjusted ceiling price. By contrast, in Victoria, negotiation does not
seem to be limited by defined floor and ceiling prices.(27)
Controlling for mass and distance, rail access charges
greatly exceed road user charges. This has led to claims that differentials
in access charges confer a competitive advantage to road transport.(28)
But just as there is no reason the total amount of revenue raised by taxes
and charges should be the same for all modes, there is no reason that
access charges should be the same for all modes.(29) Still,
the disparity between access charges for rail and road led the Productivity
Commission to comment that the differences warrant a closer look at the
current methods of charging for access in both rail and road networks,
an issue yet to be taken up.(30) It is not possible to determine
whether State rail access charges reflect the cost to society for the
use of infrastructure since the basis on which State rail authorities
calculate their charges is opaque. Indeed, private railway operators have
complained of unfair competitive practices by government-owned railways
including predatory pricing.(31)
|
Box 2: Rail Access Regimes(32)
Rail operators can seek access to rail facilities through
private arrangements, and through formal mechanisms such as provisions
under the National Access Regime contained in Part IIIA of the Trade
Practices Act 1974 and provisions under State regimes.
National Access Regime. The NAR was established under
the National Competition Policy agreed between the Commonwealth
and States in 1995. Under the Regime, a party can gain access to
infrastructure in one of three ways:
- by requesting that the National Competition Council recommend
that the Minister 'declare' an infrastructure service. If declared,
the infrastructure owner and the party seeking access must negotiate
to try to reach agreement on the terms of access
- by means of a legal undertaking made by the infrastructure
owner, and approved by the Australian Competition and Consumer
Commission
- by seeking access through an 'effective' State access regime.
Australian Rail Track Corporation. The ARTC is a Federally-owned
rail infrastructure agency, which began operations on 1 July 1998.
Its creation was the outcome of negotiations between the Commonwealth
and the States that sought to establish a 'one stop shop' service
to rail users on the interstate network between Perth, Alice Springs,
Adelaide, Melbourne, Sydney and Brisbane. The agreement envisaged
that each State track authority yield sale of access rights to the
ARTC and that common access terms and conditions would apply across
the entire network.
State Access Regimes. Each jurisdiction is developing
or has developed a rail access regime. Some regimes apply to infrastructure
generally while others apply only to rail. The National Competition
Council has to certify the regimes but so far has certified only
the NSW regime. For State access regimes to work effectively, all
actual and potential operators should face the same access terms
and conditions. This can only be achieved if ownership of the rail
network is separate from operations since, otherwise, conflicts
of interest may arise. NSW has gone farthest in 'vertically separating'
its rail functions, that is, separating track infrastructure from
train operations. By contrast, Queensland Rail is still vertically
integrated.
|
Diesel Fuel Excise
The agreement-reached in May 1999 between the Government
and the Australian Democrats- extended a full diesel fuel excise credit
to rail transport. Without this, rail's competitive position relative
to road transport would be worse. The credit is consistent with the Diesel
Fuel Rebate Scheme in that the excise will not apply to off-road use.
But if the diesel fuel excise is a general revenue tax, the principle
that taxes should apply consistently across all modes requires that all
diesel users-including the rail freight industry-pay the full amount of
the excise.
Externalities
A feature of transport is that no explicit levies are
imposed on operators to offset the non-financial costs that they impose
on the community, that is, negative externalities. While estimation of
the cost of externalities is inherently difficult, the cost is considerable.
The Bureau of Transport Economics estimated that traffic congestion in
major Australian cities costs in the order of $12.8 billion yearly,(33)
of which only part is attributable to heavy trucks. The trucking industry
claims that the cost of rail externalities such as noise and accidents
is underestimated. Still, it seems likely that the cost of heavy road
freight externalities exceeds that of rail. The Bureau of Transport Economics
estimated that (on a net tonne kilometre basis), the cost of road externalities
is in the order of seven times the cost of rail externalities for interstate
non-bulk freight transport.(34) Road accident costs are the
main reason for the disparity in the cost of externalities.
Tax Reform
The changes to the taxation system in the A New Tax
System (ANTS) package and the agreement between the Government and
the Australian Democrats will affect the relative competitiveness of rail
and road transport. The changes are:
- a reduction in the rate of diesel excise
- grants for the on-road use of diesel under the Diesel and Alternative
Fuels Grants Scheme (DAFGS) for transport in regional areas, and
- the extension of a full diesel fuel excise credit to rail transport
under the Diesel Fuel Rebate Scheme discussed above.
In addition to the above, businesses will be able to
claim the GST on purchases of diesel and other inputs as an input tax
credit.
Road and rail transport costs will fall because of the
reduction in the rate of diesel excise. Some road transport businesses
will also benefit from the DAFGS, which will come into effect on 1 July
2000. Under this scheme, grants will be paid for the business-related
on-road use of diesel and like fuels (and alternative fuels) to all vehicles
over 20 tonnes gross vehicle mass (GVM), and to vehicles weighting between
4.5 and 20 tonnes GVM that undertake operations in regional areas. While
rail transport costs will fall because of the extension of the full diesel
excise credit, the DAFGS scheme will partly offset this gain for rail
transport in regional areas.
Studies of the effects of the ANTS package on transport
have concluded that the reforms will deliver greater benefits to road
than to rail transport.(35) A Bureau of Transport Economics
study found:
If the Commonwealth's new tax system (ANTS), and
associated legislation such as the Diesel and Alternative Fuels
Grants Scheme Bill 1999, had been in place in 1998-99, average
input costs for interstate non-bulk rail and interstate non-bulk road
[transport] would have been 8 per cent and 15 per cent lower, respectively,
than actual average input costs in 1998-99. If such changes in costs
were reflected in freight rates, then growth in road's share of interstate
non-bulk freight would increase marginally at the expense of rail's
share.(36)
Competitive Neutrality
The Bureau of Transport Economics also concluded that
even after the tax reforms are implemented, charges and taxes would not
be competitively neutral between road and rail:(37)
If both road and rail paid more competitively
neutral charges, including charges for externalities, in a system
designed to fully recover costs from users, road freight rates would
rise by 12 per cent and rail rates would increase by about 4 per cent
relative to the post-ANTS situation. The net effect of introduction
of ANTS and associated legislation, in conjunction with a hypothetical
shift to more competitively neutral charges, would see both road and
rail input costs fall by 5 per cent relative to actual costs in 1998-99.
With no change in relative input costs, and in the absence of a solution
to some of rail's logistical difficulties relative to road, the long-term
decline in rail's share of the freight market is unlikely to change.(38)
The main changes needed to achieve competitive neutrality
are to impose charges on heavy vehicles that more fully reflect the cost
of their use of roads, and to ensure that both rail and road face the
full cost of externalities.(39)
The consequences of the tax reforms and the hypothetical
move to competitive neutrality are summarised in Table 1 (where the reference
point is the pre-tax reform situation where road and rail charges are
set equal to 100).

Neutrality Between Road and Rail, Working Paper 40, September 1999,
p. 32.
The Australian Trucking Association (ATA) has challenged
the Bureau of Transport Economics' (BTE) conclusions. A study prepared
for the ATA claims that the BTE overestimated the possible decli ne in
freight rates:
The analysis ... suggests that the net effect of the
simultaneous removal of the [wholesale sales tax] and its replacement
with the GST would see the GST inclusive price of trucking services
fall by only one per cent. (40)
Moreover, when other factors-such as the rise in diesel
prices resulting from the rise in world oil prices and other input costs-are
taken into account, even the one per cent fall could be swamped by these
factors, even possibly justifying a rise in freight rates.
The Australian Competition and Consumer Commission (ACCC)
has, in turn, contested the findings of the ATA study. The ACCC concluded:
On initial review of the report, the ACCC is concerned
that the ATA report heavily down-plays the effect of the substantial
reduction in fuel prices due to the New Tax System and over-states the
effect of the cost increases that have been occurring for some time
...[and]... [t]he ATA's report's consideration of cost increases in
based on a limited sample and has made assumptions, about margins in
particular, that may or may not be accurate.(41)
Response to Rail and
Road Reports
On 13 April 2000, the Government responded to three reports
containing recommendations on road and rail transport.(42)
The reports are:
- Tracking Australia. An inquiry into the role of rail in the national
transport network, prepared by the House of Representatives Standing
Committee on Communications, Transport and Microeconomic Reform and
released in August 1998 (the Neville report)
- Revitalising Rail. The private sector solution, prepared by
the Rail Projects Taskforce and released in May 1999 (the Smorgon report)
and
- Progress in Rail Reform, prepared by the Productivity Commission
and published in August 1999.
With respect to competitive neutrality between rail
and road, the Neville report recommended that:
The Commonwealth develops a more consistent, equitable
approach to transport infrastructure to ensure competitive neutrality
between modes.(43)
The Smorgon report recommended:
Governments develop an appropriate framework for
private and public sector investment that includes efficient taxing
and charging regimes and competitive neutrality between government
agencies and the private sector.(44)
The Productivity Commission recommended that:
The National Road Transport Commission should prepare-and
recommend to the Ministerial Council for Road Transport for adoption-a
revised schedule of heavy vehicle charges which ensures that each
class of vehicle pays the full cost of its road use.(45)
As noted, the NRTC's proposed changes to heavy vehicle
charges aim to overcome under-recovery of costs of the heaviest vehicles.
But the Government's response does not contain specific proposals to
implement the recommendations of the Neville and Smorgon reports.
The Smorgon report also recommended:
Rail operators to be treated like other 'off road'
diesel users for the purposes of fuel taxation.(46)
As noted, in the agreement with the Australian Democrats,
the Government agreed to the full exemption of rail from the diesel
fuel excise.
The Productivity Commission also recommended that:
The Commonwealth Government should establish a public
inquiry into road provision in Australia. This inquiry should examine:
- road transport planning processes;
- methods of investment appraisal (including the evaluation and allocation
of costs and benefits);
- funding arrangements (including taxation, charges and grants);
- the scope to improve road pricing; and
- current institutional arrangements and alternatives.(47)
The Government did not accept this recommendation. Among
the reasons given were that the Government does not see the need for another
public inquiry into road provision; institutional arrangements for road
provision are adequate; and current methods of investment appraisal allow
the Commonwealth to ensure the national highway system keeps pace with
demand and is appropriately maintained.
Conclusions
It is clear that, in practice, charges and taxes on rail
and road freight depart from the principles of economic efficiency. In
part, this is attributable to practical difficulties in designing taxes
and charges that conform to those principles as well as to conceptual
difficulties, such as estimating optimal levels of externalities and in
devising levies to reduce externalities to those levels. Moreover, the
Bureau of Transport Economics analysis indicates that even after the introduction
of the tax reforms, charges and taxes will not be competitively neutral
between rail and road. The Bills to amend heavy vehicle charges will go
some way to remedying this situation. This leaves road transport externalities
as the main factor behind the lack of neutrality.
It is unlikely that the diesel fuel excise is intended
to take account of externalities. Even if it were, the excise would be
too low in metropolitan areas. A study by Austroads concluded:
The effective diesel charge of about 18(48)
cents per litre under the proposed tax reform is seen to be a reasonable
estimate of the economic road user charge in rural areas. However,
it could lead to undercharging in large metropolitan areas, where
externalities from road transport are likely to be high. One option
to overcome this problem could be by establishing an effective form
of road pricing in the most congested areas of our metropolitan areas.(49)
This assumes that a notional part of the diesel excise
is a road use charge but, as noted, the economic basis of the charge is
questionable.
The issue of road pricing is beyond the scope of this
paper. But it is clear that road prices which reflect full economic costs,
would improve resource allocation.
Finally it should be remembered that taxes and charges
are only one aspect of government policies affecting competitive neutrality
between rail and road transport. Other areas are infrastructure investment
arrangements, access regimes, safety regulation and operating procedures
and standards.(50) Indeed, some of these areas, particularly
infrastructure funding and investment arrangements, may be more important
than charges and taxes in trying to attain competitive neutrality. Competitive
neutrality of charges and taxes alone would, therefore, still not resolve
the issue of whether government policies advantage or disadvantage one
mode relative to the other.
