Assignment: Remaining Report
For this task you’ll write a report for the NSW Division of Planning
and Trade. Given the latest Senate Inquiry into mining coverage and the rising
social consciousness of environmental issues related to deserted mines,
there’s a must assessment insurance policies and make modifications the place acceptable. The
Division is in search of recommendation on the next 2 questions/points:
The College of Sydney Web page 5
Assignment: Remaining Report
1.The Division has a pool of funds for deserted mine rehabilitation (the present pool of
out there funds within the NSW Legacy Mines Program (LMP)). Though there’s a giant checklist of websites
that want rehabilitation, the Division has narrowed the selection down that it’s in search of recommendation
on to the next 5 mines: Muswellbrook, Vales Level, Munmorah, Liddell and Wallerawang.
The federal government programme prioritises the rehabilitation of deserted mines based mostly on the
following components: public security threat, environmental threat, finish use of the land, and value
effectiveness. It’s particularly in search of recommendation on the least value possibility from a advisor
economist (you).
Use the outcomes you generated together with your assigned parameters in Lab four from the spreadsheet
MineRehabilitationFund.XLS to advise the federal government. Conduct a primary sensitivity Assessment of
the outcomes for a spread of low cost charges ( 1%, 2% and 5%).

Assignment: Remaining Report
2. Other than rehabilitating deserted mine websites, the Division want to think about what
one of the best coverage is to encourage mining firms to rehabilitate their websites to keep away from should
make extra funds out there for the NSW LMP. It additionally wants explicit recommendation a couple of small
mineral ore mining operation, Wongalee Inc. within the Hunter Valley area of NSW that’s mid-way
via the approval course of for operation. Utilizing the net bond calculator device the corporate
has calculated an environmental bond worth of $5m to be posted in full in the beginning of
operations. The native farming neighborhood is anxious in regards to the poor environmental observe
document of Wongalee Inc and declare that there’s ample historic proof that the mechanism of
a bond is insufficient. Additional, they argue that the bond is undervalued when it comes to the actual
potential value of the harm. This sentiment is echoed by native indigenous teams who argue
that in cultural phrases the undisturbed land is actually not attainable to worth.

Assignment: Remaining Report
2. Continued
An alternative choice to bonds, a broken land tax can be being mentioned. This may very well be
levied on a per hectare foundation with the intention of making an incentive for whole clear up
throughout mining operations. Wongalee Inc. claims if imposed the tax is pointless,
and native teams are calling for a DLT.
The federal government wants each particular and common recommendation. So as to reply to
claims in regards to the bond quantity, it must understand how a lot environmental harm
is likely to be brought on by the mining operation and its worth.

2. Continued
The federal government additionally wants to reply in regards to the coverage mechanism – particularly,
ought to a tax be used as a substitute of the bond. Additionally, it wants a suggestion a couple of
tax fee per ha and two tax charges have been steered : $250/ha and $500/ha. The
authorities desires to make use of the case research for this explicit mine, to place some figures
on issues, and likewise desires an informed opinion from an economist on the relative
appropriateness of environmental bonds versus environmental taxes levied on
broken land.

In Lab four outcomes for the agency (NPV of revenue) and society (discounted social
welfare), quantity of harm within the remaining interval (YT
), and worth of social harm in
perpetuity (

broken land tax (DLT).
Use numerical estimates from Lab four, and different data from lectures and
readings, to make some suggestions to The NSW Division of Planning
Trade and Atmosphere.

Lab 5: Mining mannequin with coverage choices
On this train, you’ll construct on the easy dynamic mannequin established in Lab three to analyze
the issue of non-renewable useful resource extraction and environmental inventory air pollution
externalities.
Background: The federal government is in search of recommendation on a small mineral ore mining operation. The
mine operator is Wongalee Inc. and the mine shall be within the Hunter Valley area of NSW. The
mine is mid-way via the approval course of for operation. Utilizing an on-line authorities
supplied calculator device, the corporate has calculated an environmental bond worth of $5m that
is because of be posted in full in the beginning of operations. The native farming neighborhood is
involved in regards to the poor environmental observe document of Wongalee Inc and declare that there’s
ample historic proof that the mechanism of a bond is insufficient to stop
environmental harm. Additional, they argue that the bond is undervalued when it comes to the actual
potential value of the harm. This sentiment is echoed by native indigenous teams who argue
that in cultural phrases the undisturbed land the place the proposed mine is to be positioned is actually
not attainable to worth. An alternative choice to bonds, a broken land tax can be being mentioned.
This may very well be levied on a per hectare foundation with the intention of making an incentive for whole clear
up throughout mining operations.
The federal government wants each particular and common recommendation. So as to reply to claims about
the bond quantity, it must understand how a lot environmental harm is likely to be brought on by the
mining operation and its worth.
The federal government additionally wants to reply in regards to the coverage mechanism – particularly, ought to a
tax be used as a substitute of the bond? The federal government desires to make use of the case research of this explicit
mine to place some figures on issues and likewise desires an informed opinion from an economist on
the overall relative appropriateness of environmental bonds versus environmental taxes
levied on broken land.
Duties : On this tutorial we are going to assess potential damages and discover outcomes from a per unit
tax on broken land to the proposed bond for Wongalee Inc. This can present some numerical
estimates that can facilitate the making of suggestions to The NSW Division of
Planning Trade and Atmosphere.
Outcomes for the mining firm (NPV of revenue) and society (discounted SWF) shall be
in contrast beneath no regulation, a bond and a proposed broken land tax (DLT) at a range
of charges. Wongalee Inc. claims the bond mechanism is ample to make sure environmental
safety, and native teams are calling for broken land tax.
The spreadsheet mannequin used for this tutorial is offered on Canvas: MinePolicyModel.XLS.
The outcomes you generate from this lab ought to be used to your Written Report task.
Open the file. There are four worksheets arrange for the tutorial and the task. Within the “No
regulation” worksheet would be the outcomes for mining outcomes within the absence of regulation.
The opposite worksheets “SWF” and “DLT” are for outcomes that maximise discounted social
welfare and discounted agency revenue at for a broken land tax. Recall the mannequin introduced in
the lecture for Week 6:

Duties to be undertaken:
1) Open the spreadsheet MinePolicyModel.XLS. Familiarise your self with the parameters in
the workbook labelled “No regulation”.
2) Enter the formulae to calculate mineral ore shares (Xt) broken land (Yt), whole income,
whole prices, discounted agency revenue, society’s prices of broken land, per interval tax
funds, and discounted social welfare.
three) On the “no regulation” tab, name the Solver in Excel and optimise the online current worth for
the agency with out the tax. Report the answer.
Resolution: NPV = $61.5878
SWF=-$42.357
1000 ha of broken land stay after sources are exhausted. This depart a price in
perpetuity of $80m.
four) On the “maxSWF” tab name the Solver once more and optimise discounted social welfare. Report
the answer.
Resolution: NPV = $51.453
SWF=$51.453
These values are equal as it’s socially optimum to wash up all broken land in each time
interval, therefore there are not any contemporaneous broken land prices to society.
No broken land stays after sources are exhausted. There isn’t a value in
perpetuity.
5) On the “DLT” tab name the Solver and optimise the online current worth for the agency with the
tax. To discover a really useful tax, repeat over the totally different values of taxes in cell L12.
Report the options.
College students must determine on a tax fee themselves by trial and error and attraction to principle.
As a begin (and for example) the answer for a tax fee of $250/ha on broken land the
answer can be:
Resolution: NPV = $55.027
SWF=-$40.11
1000 ha of broken land stay after sources are exhausted. This depart a price in
perpetuity of $80m. Clearly the tax remains to be too low.
6) Save the ends in every spreadsheet to make use of as data in your report the NSW
Division of Planning Trade and Atmosphere.
