ECONOMIC MODELS OF NATURAL RESOURCE MANAGEMENT.

1. INTRODUCTION TO NATURAL RESOURCE ECONOMICS

Natural resource economics deals with the production, consumption, distribution and use of raw

materials found in the earth. Sustainable resources include forest resources, fish populations and

potable water as well as exhaustible resources that include oil and natural gas, minerals and coal.

One of the major objectives is to find out how much or how little of a particular commodity or

resource should be utilized at a given time and which should be permanently conserved so as to

achieve the highest value in the present while ensuring that the resource is available even in the

future. At the core of natural resource economics are dynamic models that capture how resources

are optimally extracted over time. The Hotelling’s model provides the theoretical insights on how

the net price of any non-renewable resource including the oil must increase with time at the rate

of interest due to the scarcity factor. The model of Gordon analyzed the rationality of exploiting

renewable possessions such as the forests or the fishery resources in sustainable manners. Other

models assess issues such as the correct speed that firms need to abate pollution and the impact

of doubtfulness of actual sizes of resources. The course titled “Economic Models of Natural

Resource Management” will further feature these and other dominant policy-sensitive economic

models on environmental and natural resource management. Specific models to be included will

review issues such as depletable and renewable natural resources, environmental management

and sustainability, cost-benefit assessment with reference to the environment, common property

resources, tourism and the environment, biological diversity, water resources and management

and recycling. The course will help to introduce the student to the theoretical models as well as

to develop practical skills of how to use them for researching and making policies on use of

natural resources. Theoretical tasks will involve the concepts and real-life applications of these

P a g e | 2

models, as well as evaluations of the existing natural resource policies in the light of the models.

Students will gain the practical experience and knowledge of the main sources of literature that

will enable them to evaluate and enhance policies for some of the current complex environmental

issues.

1.1 Defining natural resources and their economic significance

Natural resources are resources developed by nature that could be utilized for economic benefit

of the people. Natural resources can be classified into: renewable resources which include

forests, fish stocks, arable land and any resource that is capable of being replenished given that it

is not exhausted beyond its ability to regenerate, flow resources which are resources that are

inherently and continually available and stock resources which are resources that are fixed and

depletable such as fossil water, fossil fuels, minerals and metals. Since most natural resources are

scarce while human economic wants are infinite, scarcity of resources and efficient distribution

forms core of economics. Natural resource economics as a discipline, focuses on studying how

we can utilize the natural resources to meet the needs of mankind, it employs models to examine

temporal trade-offs between the present consumption and investment in resource stocks to be

consumed in the future and uses approaches such as cost-benefit analysis to examine questions

such as the correct rate of extracting resources. Ecosystems form components of natural capital,

offer a stream of net benefits which are economic goods and services in the form of food, timber,

water, favorable climate, recreation and pollution absorption among others, ecosystem

destruction due to greed for more land, forest destruction, species loss and pollution are very

expensive to bear with natural capital. Thus, the monetization of the effects of resource

deterioration offers an interest in protecting the scarce assets. The theoretical frameworks of

natural resource economics also help in policy formulation in many arenas as these principles

P a g e | 3

expose the actual cost that is embedded in private market pricing of natural inputs such as fossil

fuels and water that are underpriced relative to their total value to human beings. Knowledge of

natural resource economics is becoming more and more essential for developing and emerging

countries shaping their future economy and policy so as to ensure sustainable utilization of earth-

endowed stocks, natural resource economics provide a synthesis of ecological sustainability for

development of policies to promote efficient use of scarce natural resources to sustain its stocks

for supplying necessary inputs for human welfare.

1.2 History of natural resource management

The historical management of natural resources can be traced back to several thousands of years

as early man started to modify the environment to enable efficient hunting and gathering. But

organized huge scale natural resource management is comparatively a recent phenomenon that

came up only in the twentieth century. Some of the historical milestones that brought change to

the conservation advocacy include the Progressive Era conservation crusade of the early 1900s,

the Dust Bowl catastrophe of the 1930s that resulted in new soil conservation crusade, and the

beginning of the environmentalism period in the second half of the Twentieth Century. The

creation of governmental agencies and policies that specialize in forest, range, wildlife, water

and other habitat management promoted more organized strategies. Over the years, policy

formulation to do with natural resource utilization and conservation has strategized the use of

economic principles which include emissions trading as market-based solutions that result in

economic incentives for the reduction of emissions and conservation banking as policy

instruments that provide for functioning of market forces to support passive conservation of

habitats by land owners. In the present time, natural resource management makes an effort of

attaining sustainability through the use of scientific, economic and policy instruments. Economic

P a g e | 4

models employed include bioeconomic optimization models that define the highest possible

ecological yield, cost benefit analyses for the commercial exploitation of resources, non-market

valuation techniques that estimate the worth of certain services offered by natural environments

and econometric resource forecasting which predicts resource availability under given

management conditions. From the natural resource economic perspective, nature is regarded as

made up of stocks which afford human beings with useful products and services that must be

conserved and studied akin to financial assets and other tangible products forming the basis for

today’s natural resource management system.

1.3 Principles of resource economics

The most basic concepts of natural resource economics form an umbrella under which strategies

for management of scarce environmental and natural resources can be understood. One principle

of the economic definition of natural resources and assets is that these resources have elements

of public good since they are both non-exclusionary and non- rival in consumption and yet

possess economic value, both usufruct value where they are used, for instance, for timber

production or recreation, and existence value, whereby people place value on the mere existence

of the resources incurring market failures and the need for public policy. Other important

principles are assessing natural resource and environment for economic efficiency with a view of

maximizing net benefits; applying right time frame in evaluating resources, other costs and

benefits with right discount rates; equity considerations and ensuring costs do not fall unfairly;

applying the precautionary principle where probable irreversibility or probable catastrophic

losses exist; and, risk sensitivity and risk of outcomes of choices in managing resources. Basic

concepts of resource economics are the welfare economics using concepts of consumer and

producer surplus; valuation of the non-market environmental resources; existence of externalities

P a g e | 5

and handling of information failure; being aware of substitutes existing in resource allocation;

developing right pricing structures for the resource use (user charges of resource rents); defining

clear property rights; and undertaking efficient cost-benefit analyses to inform environmental and

conservation policies. These principles and tools present the basic framework of the economic

approach to analyzing sustainable management of natural resources.

1.4 The role of markets in resource allocation

Markets are very important in the distribution of natural resources with price signals as the main

controlling tool. Market prices serve to moderate the utilization and access to resources

throughout the economy. Market prices of natural resources in relation to other commodities or

goods determine the distribution of these resources in the market through giving both the

producer and consumer signals and motives. For instance, if there is scarcity in a natural

commodity such as timber owing to enhanced housing needs, the market price for timber will go

up and the suppliers will then feel the need to offer more timber in the market to supply this

increased demand. Higher price reduces supply and increases demands for timber, for the extra

constructions that are a result of the increased demand for housing. This process of market

adjustment helps in guiding the distribution of resources across the economy and the proportion

of land, capital and labor that will be utilized in producing goods such as timber and lumber as

compared to other products and services that are preferred by consumers. If there are

externalities or market imperfection relating to a natural resource, then there is need for

government action or policy adjustment in order to get the resource to the right place in the

economy. For instance, the open-ocean fishery resources are easily exploited to the level of the

tragedy of the commons because there is no limitation on catch amount because the resources are

common. It is for this reason that government-imposed catch limits or fishing quotas are required

P a g e | 6

to avoid the occurrence of market failure in the fishing sector, entailing fishery depletion and

misallocation of resources to this sector. Economics serves the purpose of identifying the

problems and issues that may exist in resource allocation, and offer understanding of what kind

of instruments and actions the government should take to make markets beneficial to the

consumer, as well as being friendly to the notion of sustainable use and management of natural

resources in the long run. To sum up, it reveals that market price signals and incentives ensure

how natural resources are distributed across the economy with the help of economics while

determining the time and way of how government policies can correct or avoid market failures.

1.5 Challenges in valuing natural resources

Valuing natural resources can be a difficult proposition for several reasons. Second, some

environmental assets such as clean air, non-renewable species of plants and animals have no

market price and thus their worth cannot be valued. Since these are referred to as non-market

goods, environmental economists have come up with ways of determining their economic values

such as the contingent valuation technique or hedonic pricing, but these are often costly and

convoluted by design. For instance, contingent valuation surveys can only be constructed in a

specific manner to ensure that the willingness to pay statements provided by respondents are

genuine. Second, they are often long-lived benefits that accrue over many years, and hence

economists often have to discover the present value of natural resources using the technique of

discounting of future benefits. This is usually achieved by discounting the expected future values

to arrive at a net present value using the right discount rate. But deciding on the right social

discount rate which quantifies the society’s patience to wait for what it wants rather than have

what it wants now can be very subjective. Evaluating a company can be affected by the selected

discount rate applied on the cash flows. Third, it is important, when planning the management of

P a g e | 7

natural resources, that the expected increase in demand/supply in the future is taken into account,

and the uncertainty of factors that will affect supplies in the future. Forecasts could again err and

result in future value of natural assets being grossly underestimated. In the case of resources such

as fisheries, an assessment of risk and uncertainty in terms of population size and structure is

critical but not straightforward, frequently based on data derived from past experience only. The

valuations of resources should be capable of giving a measure that goes beyond mere present

utility but also the option value of future utility. Another problem that natural resource

economists face is the challenges that are associated with the process of assembling all the

relevant information necessary to achieve complete and accurate valuations. The issues in

valuation include but are not limited to measurement problems, long time horizons, uncertainty

in assessing future supply and demand, and sustainable considerations for the valuation of

natural capital and flow resources. But valuations do contain many assumptions and results can

also be sensitive to the methodology chosen to solve these problems economists apply a variety

of methods which have to be adapted to the specific context. It is still possible to refine the

existing models for evaluating natural resources, and this remains a relevant topic of research.

1.6 Introduction to key economic models

Natural resource economics is focused on the issue of how natural resources, that are, fossil

energy, minerals, fish, forests, lands, and water should be produced, distributed, and sustained.

Some of the popular economic models applied to natural resource economics include: The

models correct for market failures associated with public goods, common pool resources and

externalities. Some of the models commonly used include static and dynamic efficiency models,

cost benefit analysis, optimal control theory, Markov decision processes and even agent-based

modeling. Structural models like the Gordon model of fisheries exploitation are used to allocate

P a g e | 8

natural resources efficiently across distinct time horizons without capturing intertemporal

conditions. On the other hand, the dynamic efficiency models like the dynamic Gordon model

contains natural growth rates alongside the discount rates for a better intertemporal optimization

technique. Cost-benefit analysis balances policy choices by comparing the incumbent policy and

the social cost and benefit of natural resource projects using time discounted social cost and

benefits, or long-term social cost and benefits. Optimal control theory employs Hamiltonians and

co-state equations to find the extraction of resources that respect physical growth constraints

while reaching for the maximum of economic rent. Markov decision processes are used in the

modelling of agency decisions in a stochastic world in the case of renewable resources that

undergo dynamic changes. Agent-based models involve the systems that demonstrate the

decentralized self-interested activities of various stakeholders in relation to the common pool

natural resources. Each of these prominent economic models offers distinctive guidance for

policies on how to conserve, allocate and rationally use limited resources over time between

generations.

2. RENEWABLE RESOURCE ECONOMICS

Renewable resource economics studies the utilization of renewable biological resources which

has potential for regeneration within reasonable time frame like forest, sea fish stock, wild flora

and fauna within the economically feasible time span. One of the basic frameworks is

bioeconomic modeling that captures dynamics of the human economic behavior in relation to

biological growth. This presupposes key ideas such as maximum sustainable yields, optimal

harvest policies, property rights, the common pool resource, and intertemporal choice. Trade-offs

between present and future consumption can be described quantitatively with the help of

theoretical frameworks such as the Gordon-Schaefer model. They describe incentives which

P a g e | 9

exist in front of individual resource harvesters if their objective is to achieve the highest accrual

of profits in the course of time. Sometimes a socially efficient extraction regime differs from the

private ones by limiting the amount of the resource withdrawn in the initial period to allow the

stocks to replenish. There is therefore need to design policies that would ensure that individual

private incentives are also in tandem with the social objectives being sought. Such measures

include using of rules and laws, levying of taxes or providing subsidies, putting in place of

tradable permits or undertaking of quotas so as to establish exclusive property rights. A

drawback, however, is handling embedded complexities and risks relating to ecological

frameworks. Stochastic models and adaptive management procedures allow for policy revision

as new information becomes available. Other issues are distributional consequences across

diverse agents, employment consequences of conservation policies and criteria such as

sustainability that go beyond established efficiency criteria. Besides, renewable resources mostly

contain complex adaptive systems that are characterized by nonlinear behavior that is why, stress

surprises or shifts of regime are possible. Resource management on the other hand calls for

precaution, monitoring, and innovative and adaptive institutions that can be shaped according to

circumstances and knowledge. One cannot always achieve a positive synergy when trying to

bring human and natural systems in alignment for the long periods of time and over the uncertain

futures.

1.1 Fishery models and optimal harvesting

Fishery models belong to the effective and widely used tools in the theory of renewable resource

economics. These models study the fluctuations of fish stocks and endeavor to find the best

polices regarding the exploitation of fish stocks so as to reap the most benefits all through. One

of its major areas of interest is the bioeconomic models that involves integration of biological

P a g e | 10

growth models of fishery together with the economic assessment. These models involve factors

that relate to fish stock recruitment, fishing capacity of the fishery, prices that can be fetched

from the fish harvest activity and the costs incurred in the process of fishing. They lead to advice

concerning suitable fish catch quotas which can be beneficial in the long term from an economic

point of view. A historical model in this field is the Gordon Schaefer model which employs the

logistic growth functions to explain population trends and integrate an economic evaluation of

the open access and the optimum fisheries management. This indicates the problem of

overfishing and dissipation of rents as a result of open access and how through management of

effort, the optimal yield is attained. Extensions account for various factors such as uncertainty,

spatial heterogeneity, and mobility, age composition, retention and mortality, climate change

effects, interactions with aquaculture, fishing effects on gene flow and other realities of modern

fisheries. Key questions examined via bioeconomic fisheries modeling include: The questions

are: at what kinds of fishing effort will sustain economic returns be feasible in the long run? How

does lack of certainty concerning stock of stocks dynamics and recruitment influences the right

policies? Which spatial constraints and shifts of fishing areas are likely to enhance catches? In

what way can the actual behaviors and the investment plans of fishers be altered or steered by

taxes, subsidies, or property rights to attain economic and biological goals and

objectives? Bioeconomic modelling sheds light on these matters and assists the policy

formulation for managers who seek sustainable fishing yields of resources over long-run with

regards to the biological and economic stocks.

1.2 Forest management and rotation models

Forests are one of the most typical examples of a renewable natural stock in the context of

economics. This is an example of a natural resource that is extracted and used as fuel, timber

P a g e | 11

from forests, but with careful usage forests can always be replanted for future use. Another

subtopic within the field of renewable resource economics specially in relation to forestry is the

right time of harvesting or in this case called the rotation age, which is the right time for cutting

down trees and planting new ones to get the highest amount of money possible. Most basic

models revolve around factors such as the expected growth of the trees, the cost of regeneration,

and the prices for the harvested timber. Other developed forest management and rotation models

include more factors such as the interest or discount rate, the risk of fire or disease, storing of

carbon and use by the public for recreation. These economic models help the forestry managers

and policymakers in balancing trade-off options that bring out the maximum economic benefits

when several rotations are considered, at the same time protecting the forest asset. These models

involve specific techniques for determining the value of forest land, such as Faustmann’s formula

which is used to determine the land expectancy value of a forest for an indefinite number of

rotations. The Hartman model builds on this to also incorporate the different quantities of timber

that may be produced in different years. Other contemporary models analyze the uncertainties of

growth rates and timber prices using stochastic and dynamic programming techniques. Other

assessments may also encompass other indirect values of those forests such as conservation of

biological diversity, wildlife, soil and other values that cannot be expressed in terms of timber

product markets. As for the more recent development, modeling of climatic change effects which

influence growth and disturbance of the forest has also been incorporated in the process. In sum,

mathematical models of the forest economics help in explaining long-term development and

provide solution for sustainable management to achieve successful harvest for the landowners

while keeping the forests for decades or centuries. The models yield valuable policy information

P a g e | 12

for determining allowable cut levels, cost-share arrangements, conservation premiums and any

other public initiatives that define this renewable but scarce resource.

1.3 Water resource management

Water is an essential resource that is renewable but limited to means that its use requires proper

management in order to produce enough to meet the ever rising demand. Water resource

management demonstrates how a scarce resource can be efficiently distributed employing

microeconomic principles. In particular, they use models to identify the potential and intensive

use of surface and groundwater resources. This involves determining the probability and need for

using water in households, industries, and for farming and evaluating the pros and cons of

usage. Demand increases with population and economic development whereas supply is

constrained by geographic availability of resources and rates of resources generation. The best

way to control the demand may be through pricing structures like usage fees or water right

trading. However, policy makers need to look at the issue of pricing from another angle in terms

of the ability of people, within different income bracket, to afford the price. Another justification

for intervention is externalities – here, with each individual’s water usage reducing availability

for others, this is a classic instance of the tragedy of the commons. One of the methods that

governments use to control the high extraction rates is the use of command-and-control

regulation. Others may include market-based policies such as water rations that may encourage

users to reduce consumption. These tests assist in an evaluation of whether the marginal social

benefits are equal to the costs borne by water consumers and the industry. These hydro-economic

models that combine the hydrologic dimensions with the economic optimization could provide

more knowledge about sustainable allocation. They approximate scarcity rents and shadow

prices to guide water to where demand is high. In this way, such economic structures let

P a g e | 13

governments provide integrated and sustainable water quality and ecosystem service

management for average human consumption needs. This entails the need to build a consensus

across the divide and shift the perception of water as a public good. First, it is important to note

that the application of RRE is beneficial for water resource planning, but the utilization of some

of its components may be ineffective in the case of a relatively low level of institutional

development.

1.4 Renewable energy economics

Renewable energy economics covers the various economic traits and the markets of renewable

energy resources, specifying solar power, wind power, geothermal power, hydroelectric power

and biomass power. One of the key challenges is that renewable energy sources are still costlier

than oil-based sources; hence, governments have to provide subsidies for production, investment

tax credits, and mandatory renewable portfolio standards for the industry to expand. But the costs

have come down significantly in the last decade, especially in the case of solar and wind energy

due to the technical upgrades and cost-effectiveness in fabricating and installing the

equipment. Market analysis indicates that sustainability of cost cutting require more technical

innovations, enlargement of production lines and market development. While the initial

investment is marginally higher in renewable energy, the benefits in terms of economic returns

are substantially higher than in the fossil fuel industry. Most notably, renewables have zero

marginal fuel costs due to infinite resource availability in form of sun, wind, water currents and

plant crops. This make operating costs possible to be very low as long as initial facilities are put

in place. There are also other external economic benefits which are derived from the differences

in the cost of avoiding environmental impact of fossil fuels. Also, renewable energy such as solar

power generated from rooftops are sources of locally produced and therefore, imported energy is

P a g e | 14

limited. Expansion of renewable power benefits national security while developing green jobs in

generation, installation, construction and servicing of renewable power equipment in America.

Governments must consider these economic advantages, however, against consequences for

ratepayers of incentive programs which disperse initial cost. As more sound policies on

renewable energy are implemented coupled with technology advancement in the long run, the

economics of the renewable energy should further improve in the next decades in power

generation, heating and transport sectors. Payments will be needed for countries across the globe

if they are to implement necessary carbon emissions reductions required under global climate

change treaties.

1.5 Sustainable yield concepts

Sustainable yield is one of the important concepts that are commonly used in the management of

renewable resources. It is defined as the highest replenishment rate that can be achieved for a

renewable resource without causing decline in the rate at which it can be replenished in the

future. For instance, in the context of forestry management, yield is understood as the annual

allowable cut or the maximum level of wood production that can be attained without

compromising the productive capacity of the forest. There are several models that have been put

in place to forecast sustainable production for such renewable resources such as fish, trees,

grazing area and wildlife. A simple production model is the surplus yield model, which computes

optimum sustainable yield based on the growth rate of the resource and its capacity or maximum

stock. Sustained and more comprehensive bioeconomic models, on the other hand, also factor in

elements such as prices and costs. The target is to find out the right level of harvesting which will

give the maximum of present value of the revenues to be received in the future. This balance is

important – over exploitation means leaving a lot of gains untapped while under exploitation

P a g e | 15

means over exploiting the natural resources beyond their ability to reproduce themselves. The

maximum sustainable yield is used in a more specific context of maximum allowable catch or

production which could be sustained in the long run. But assessment of sustainable yields is not

very easy due to several constraints like variations in conditions of environment, the effects of

climate change, problems of measuring resources and interaction of ecosystem. Most of the time

people call for adaptive management tactics whereby the policies to be followed in the

harvesting process changes depending on the data that has been collected in subsequent

surveys. Another aspect includes the capacity to adapt the focal resource, together with related

ecosystems, against shocks present in a system. In total, creating accurate models for predicting

sustainable yields continues to be a crucial endeavor within the sphere of renewable resource

economics.

1.6 Ecosystem services valuation

Ecosystem services valuation is an essential idea in renewable resource economy and resource

management. This means establishing the worth of the services that are offered by natural

systems in supporting human activities. Ecosystems provide invaluable services that are essential

in making human life healthy, wealthy and beautiful by providing services like purification of

water acting as cooler or warmer depending on global temperatures, pollination for crops and

recreational beauty for tourism. However, it is often the case that markets do not signal these

services adequately enough in economic terms. ESV works to estimate the worth of these

ecosystem services in an economic way with the help of methods like cost-benefit analysis. The

rationale for the research is that when people realize how much societies benefit economically

for functioning ecosystems, then improved management of these valuable renewable resources

can be achieved. These are based on market price approach where the price of the ecosystem

P a g e | 16

goods is determined, avoided cost approach where cost of the ecosystem service is estimated in

terms of cost saved when the ecosystem service is provided, replacement or substitution cost

models where value of the ecosystem service is estimated by finding a substitute service, travel

cost model used in recreation services, hedonic pricing where the value of land is determined and

willingness to pay approach where people are asked their willingness to pay It is not without its

issues; valuation of some EUAs remains uncertain, and not all externalities can be accurately

expressed in monetary terms, yet, the overall idea is to improve the integration of environmental

consciousness and mechanisms for ecosystem stewardship into neo-classical economics, the

economic policy planning and budgeting, business and corporate strategy and decision-making,

cost-benefit assessment of investment projects through recognition of our dependency on

ecosystems’ supply of naturally replenished stocks It provides an alternative school of thought

within renewable natural resource economics and policy to the conventional one where focus is

placed only on extracting value from built infrastructure and exploitation and development

without sustainability.

3. NON-RENEWABLE RESOURCE ECONOMICS

Non-renewable resources are resources that are scarce and can only be used up in the next

generation and they include fossil fuels, minerals and metals. The classical economic models of

exclusive use of no-renewable resources reflect certain coherent assumptions such as perfect

competition, complete information and rational expectations. They analyze consumers’

behavioral patterns to limited availability and price indications. For instance, the Hotelling model

evaluates how a producer with the objective of maximizing profit operates in a perfectly

competitive market where the reserve is limited, the costs of extraction are increasing over time,

relevant discount rates, and demand are known. Herfindahl model builds on these by allowing

P a g e | 17

for more realistic depictions of the marketplace in that more concentrated market power in the

hands of producers might result in higher rates of depletion. By extending cost-benefit analysis

to include exploration, models that regard incentives for expanding deposits and known reserves

affected by technology advancement cost of exploration and expected prices are considered.

Other economic appraisals assess other policy tools capable of addressing market inefficiencies

associated with the absence of correctly priced external costs in utilizing non-renewable

resources such as burning of fossil fuels which pollute the atmosphere. Some of the policy

instruments considered in theory and as grounded into practice involve Pigovuian taxes, cap-and-

trade mechanisms, technology standards, and incentives for conservation or for generation of

new, cleaner energy. Key drivers that impact the outcomes of best use rates include assumptions

made about the degree of substitutability, recycling technologies for used material consumption

and price elasticity of demand. Estimation of these parameters through the empirical models

involves the use of historical data but it is quite a challenge to predict a market potential of a

substitute or a new technology that has not emerged in the market.

1.1 Hotelling's rule and resource extraction

Hotelling’s rule is a principal paradigm in non-renewable resource economics that can shape the

optimal consumption of scarce resources in the process of extraction. It asserts that the price of

the non-renewable resource has to rise at the rate of interest to eliminate the reason why

extraction would be deferred which is not efficient. This is because receiving the amount of the

resource now, investing the proceeds and then selling back the amount later would be more

profitable than extracting more at the present price. Through his analysis, Hotelling proved

mathematically that spread between price and marginal extraction cost increases at the rate of

interest along the efficient extraction path. This can be so for both the producers of animal

P a g e | 18

products and the policy makers. This is because producers have to pass the cost increase onto

consumers to fund further increases in extraction capacity since lower quality and more difficult

to obtain resources must be exploited. Hoping that the real resource price will not increase in the

future, companies will not invest in such kind of stock today to ensure an optimal rate of

extraction. This is due to the fact that policy makers wish to encourage the conservation of

resources but do not wish to cause a sudden surge in prices which could be caused by the tax

therefore policy makers have to look at future interest rates as well as extraction costs. High

taxes on products if set in advance reduce its supply to the market while setting low taxes on

products may lead to an increase in demand and a consequent steep price increase in the future.

Elegant as the theory might be, Hotelling’s rule raised practical problems in accurate

measurement in the non-renewable commodity markets. Due to the enhancement in extraction

technologies’ speed, discovery of new low-cost resources and fluctuations in interest rates, the

“Hotelling path” of prices and marginal costs becomes highly undulating. But the above basic

logic can never be dismissed as real resource policies need to have this form of change to

respond to new events of cost of extraction and availability of supplies and market conditions.

1.2 Mining economics and optimal depletion rates

The extraction of non-renewable natural resources such as oil, natural gas minerals and metals

requires deciding on the maximum rate at which these exhaustible resources should be extracted

and sold over a given amount of time. One of such concepts is Hotelling’s rule, whereby net

price of the exhaustible resource should increase at the rate of interest, with the remaining worth

of the resource getting progressively scarcer. Through measuring the benefits and costs

associated with mining, the firms in the mining industry seek to post the highest possible level of

profit by mining as many ounces as possible until the marginal cost of mining is equivalent to the

P a g e | 19

net price of the resource in the market. Nonetheless, from the perspectives of a society, the

objective is to sustain intergenerational equity and conserve non-renewables by depleting them at

a slower rate. There are models like the Herfindahl model that address these objectives noting

that marginal extraction/sales revenues exactly equal current net price plus the user cost of

depletion, which means the scarcity of the resource. The user costs also include the factors like

the present reserves and extraction technologies. In addition, other factors that are characteristic

for real economy, including market power, ecological impact, and geopolitics, can differ

significantly actual rates of depletion from the theoretical ideal. Natural resource economists still

study such dynamics, with the objective of developing superior policies like severed mineral

taxes, tradable extraction permits, and strategic petroleum reserves in an attempt to enhance

social welfare in the light of non-renewable resource limits. All in all, the subfield of mining

economics endeavor to strike between business imperatives, macroeconomic effects, geopolitical

imperatives, environmental conservation and the intergenerational usage of balance in striving to

identify the best practice principles for utilizing such valuable, though clearly finite, natural

capital stocks.

1.3 Oil and gas economics

Crude oil and natural gas are essential Non-renewable resources that are significant for the global

economy. The economics entail supply and demand, pricing structures, and management

frameworks of these fossil fuels which are largely composed of models. On the supply side of the

resource market, factors such as the cost of exploration, cost of production, the extent of the

remaining reserves, and the technological factors influence the output volumes and cost of

extraction. On the other hand, energy consumption is influenced by factors such as Economic

growth, population increase, and changes in weather season. The price at which buyers purchase

P a g e | 20

goods is influenced by the available supply in the market while the price at which sellers sell

their goods is influenced by the demand in the market, often characterized by high supply

inelasticity that is often witnessed in the oil and gas markets making market prices highly

volatile. Of particular concern for the economics of oil and gas, subsidies, environmental

policies, pipeline permits, and strategic storage are influenced by both firm and nation initiatives.

Eventually, the economic models have to assess the rates of decline of the oil and gas reservoirs

and integrated them with new discoveries, as well as technological advancements for projecting

supply-side limits in the future. Concerns relating to externalities such as climate change also

bring into focus social cost of using fossil fuels thus put pressure on econometric models by

requiring them to incorporate externality costs. In choosing the best mechanisms of managing oil

and gas resources, consideration of these supply constraints, environmental externalities, risks to

energy security, and costs and benefits as against renewable energy is crucial. The challenges of

finding the right balance are hence apparent for government policymakers. In summary, the

analysis of the economics of oil and gas resources, as a sub-discipline of energy economics,

requires the use of statistical tools, game theory, futures analysis and cost-benefit analysis of

policy options to sustain the economically rational and socially optimal depletion and

development of these vital, finite resources under recurrent growing environmental constraints.

1.4 Resource scarcity and substitution

As natural resources such as fossil fuels and minerals become scarce because they have been

extracted and used, their prices are inclined to go up. This scarcity and price increase trigger

attempts by the consumers, producers, and governments to look for an alternative. For instance,

while more difficult to access copper ores become scarce, miners have to dig deeper and go

farther afield to obtain lower grade ores, hence raising copper prices. In this regard, the

P a g e | 21

manufacturers use aluminum or fiber optic wiring which have relatively become cheap. To

minimize the risk of future scarcity of strategic minerals, governments may subside the research

for new materials. The degree of substitution is still possible depending on the available

substitutes. Few resources such as oil are not easily substitutable because of their characteristics

such as energy density that is crucial for transport and manufacturing of chemicals and plastics.

Thus, the neoclassical school agrees that raising the price on non-renewables also increases the

efficiency of use and recycling, thus increasing effective supply. However, it might be necessary

for the utilization of renewable resources to increase displacing non-renewable inputs in some

economic sectors as scarcity of the latter progresses. Some of the transition costs relating to such

shift could however be mitigated through measures such as carbon pricing which takes into

account costs borne by the external environment in the extraction of resources. But in order to

optimize these transitions over the time, some long-term cost must be modeled as well as the

availability of substitutes. Timing is critical in the application of substitutions, if it is done

earlier, it merely squanders more valuable non-renewable resources while if it is done later it will

lead to disruptions in the economy. Appropriate policy and economic instruments are required for

managing these tradeoffs adequately.

1.5 Intergenerational equity in resource use

Applying the intergenerational equity in regard to the use of natural resources in the case of non-

renewable resources means that the depletion, utilization as well as consumption of the limited

resources such as the fossil fuels, minerals, and metals should fairly balance between the current

and future generations. Since these resources are finite and exhaustible, there is a policy choice

between the amount of these resources properly consumed by the current generation and the

amount properly preserved for the future generation. This issue is tackled in theory by

P a g e | 22

economists using models of the so called golden-rule path, which indicates the optimal rate of

extraction with time controlling for the current benefits of resource extraction and the future

costs of resource depletion and scarcity. For instance, the Hotelling model of optimal extraction

of non-renewable resources states that optimal extraction rates should be defined relative to the

rate of interest – resources should only be extracted if their prices rise at a rate no slower than the

rate of interest. However, models that only look at the utility maximization of the current

generation may exhaust the resources without proper consideration of the generation that is to

come. Intergenerational equity can be taken into account in economic models by the integration

of sustainability criteria and the long-term social discount rates wherein the utility of future

generations is assigned a value that sufficiently seeks to address basic resource requirements.

Other strategies to operationalization of intergenerational equity in non-renewable resources

extraction include policy measures like extraction taxes, partial resource conservation, recycling,

and replacement by renewable resources which ensures that the resources are utilized sustainably

to foster the exploitation of the resources over the generations and periods of extended

oscillations in prices. However, not all policy interventions are without political barter and public

opinion considerations especially in an erected democracy where short-term policy thinking may

reign. In sum, integrating equity and welfare of future generations in non-renewable resource use

modeling/analytics and policies in the present is still an unresolved economic problem before

short-termism.

1.6 The economics of recycling and resource recovery

Recycling and recovery of resources are critical when the fossil fuels and minerals are scarce

because the cost of acquiring them is high. Recycling is another element of reducing the usage of

non-renewable materials because it involves the extraction of useful materials from waste

P a g e | 23

products and utilization of such materials. From an economic point of view, recycling decreases

the call for new material, decreases costs incurred in the disposal of waste, and provides cheap

material for product manufacturing. Nevertheless, recycling also entails additional costs in a

form of collection and processing equipment and shifts in production to accommodate the

utilization of recycled products. Nevertheless, there are several concerns related to these

investments and systemic changes from the economic perspective. First, the costs of collection

and processing should not exceed the Scrap Value, that is the value of the materials collected in

the market - otherwise it is cheaper to use virgin material. Second there is a need for policies

such as disposal taxes or mandates to back up recycling since recycling requires market pull in

the form of recycled material. Last but not least, industries need to cooperate across the supply

chains to support the recycling processes and reuse of materials at scale – for instance, consumer

product firms collaborating with packaging manufacturers to enhance materials’ recyclability.

The analysis indicates that when favorable economic conditions and partnerships exist then

recycling as well as remanufacturing can affect positive economic growth in terms of creating

domestic employment and in some instances; export. Only remanufacturing is expected to

facilitate more than 0 billion in economic value. And as mostly all countries and companies

begin to shift to circular economy where the value of materials is retained for reuse, there are

many opportunities for job generation and economic growth and at the same time safeguarding

non-renewable resources. Nonetheless, these benefits can only be realized when the economic

structures, the business models as well as the interactions between different industries are

transformed, which means that recycling is not enough on its own, there is a need for these

transformations as well. The complexities of such processes and hence it is important to

undertake a comprehensive analysis of all these factors for the purpose of developing effective

P a g e | 24

policies and strategies that would allow for the efficient recovery of resources as a foundation for

economic development.

4. MARKET FAILURES AND POLICY INSTRUMENTS

Market failures occur where otherwise efficient markets lead to inefficient outcomes in resource

allocation. There are four principal forms of market failure associated with natural resource

management these are externalities, public goods, common pool resource and information failure

or uncertainty. An external cost is incurred on individuals other than those involved in a

transaction, while an external revenue is received from such people. Environmental pollution is

therefore an example of a situation where the social costs are higher than the private costs, thus a

negative externality. Some policy measures include regulation and pollution taxes or trading of

permit schemes to ensure that polluters bear the cost of their polluting activities. Market failure

occurs since public goods such as clean air, if the concept of biodiversity, or any ecosystem

service, are non-rival and non-excludable. This is because governments may have to intervene

directly through subsidies, public protected areas or other instruments such as payment for

ecosystem services. Open access common resources are easily congested, overused and at risk of

being destroyed because many individuals can use them freely. Fisheries are an example of the

common pool resource that is a highly risky open access resource that may easily become

overfished and overstocked if there are quotas or restraints on the quantity that can be caught and

the number of boats that can participate. Policy measures vary from the complete deregulation

and sale of the commons, to turning them over to the local people for self-management to a

complete imposition of a state regulation of the allowable yield or effort. Lack of information or

uncertainty regarding such benefits and costs of the use of the resources or their preservation also

hampers the rational decisions by the private entities. Thus, the various programs include

P a g e | 25

monitoring and reporting activities, certification systems, and research funding to encourage

higher social efficiency of extraction or ecosystem management because of the challenge posed

by biophysical structure and knowledge constraints.

1.1 Externalities in natural resource use

There are various types of externalities and most of them are considerable sources of market

failure in natural resource use and management. They arise when one individual or firm affects

other people who are unrelated with the transaction but these effects do not feature in the price

determination process. Most activities involving natural resource utilization and production

result in negative external economics because society bears the cost of these activities while the

producers and consumers of the resources do not fully bear the cost of their actions. These are

direct effects on ecology through extinction of species, habitat degradation, and pollution from

extraction, and indirect effects on the global environment through the release of carbon and

contribution to climate change. The difference between social marginal cost and private marginal

cost gives a signal that prompts over-exploitation and wastage of natural resources beyond the

socially acceptable levels. Taxes/exemptions or tradable permits are effective policy tools that

can be employed to address externalities in natural resource consumption. Environmental taxes

use the concept of negative production externalities, which is a fee that is charged on producers

who produce public ‘necessities’ like pollution and environmental degradation. They encourage

firms to minimize external dis-earning activities. On the positive side, with subsidies,

individuals, companies, and governments can engage in more activities that would promote

social welfare such as environmental conservation and management of scarce resources.

Traditional permit systems on the other hand, create a cap on the total level of externality-

generating activity, so that the permits can be traded in order to meet this capped level at the least

P a g e | 26

cost. This gives the necessary push to adopt the cleaner production technologies and techniques.

Appropriate policies can be used together with the classification of the type and the magnitude of

externalities to control the usage and exploitation of natural resources in a manner that increases

social net benefits. They are effective based on the surveillance systems they have in place,

reinforcement systems in place and other factors such as policy volatility.

1.2 Common pool resources and the tragedy of the commons

Common pool resources are resources that are natural resources such as fisheries, forests,

underground water and pastures that are rival and non-excludable. This means that as a member

of the community, ones use of the resource reduces the amount available to others and hence

access is easily compromised. Such a scenario may result in the tragedy of the commons – the

economic issue of resource depletion. Lack of regulation in extraction is characterized by

individuals acting in the best self-interest and deplete resources more than an optimum level.

One is ocean fisheries, which involve the catching of fish in the oceans through fishing fleets.

This has the effect of allowing too many boats for too few fish, thus it is very difficult to bar

fishers, hence the open access. Reducing the amount of fish through an individual quota is

regarded as an economic policy measure. This allots individual transferable quotas that in total

cannot exceed the overall sustainable catch. Quotas can be purchased/sold by fishers which

creates an environment of least cost. Although the quotas effectively maintain the count of fish in

a region, there are problems related to high cost of monitoring the program and the large

company’s control over a large portion of the quota. In specific, the resources that are located

beneath the surface of the ground such as the water that is located in the aquifers is also not

immune from facing similar challenges in the same way that the aboveground resources are not

immune to facing similar challenges when they are located in shared property. Farmers, on their

P a g e | 27

own, choose how often to pump water for irrigation, pulling the water table beneath the socially

efficient level. A policy can mean drilling of new wells to increase the supply of the commodity

in question or limiting extraction through the use of pumps. The former is a source of concern

due to its finite nature, while the latter can only be achieved through collaboration. Metered

pumping satisfies user conflicts but supervision of water usage is informatively intensive.

Privatization defines property boundaries and is not an equalizer and still requires governing

institutions. Thus, open access leads common-pool resources closer to their state of extinction

and is a significant market failure. Policy instruments regulate self-serving behavior and ensure

that actors’ motivation is aligned with sustainability objectives. Developing these tools entails

engaging equity, efficiency, and the various physiological characteristics associated with the

individual resources. Thus this option says, ‘There is no remedy in politics; only policy and

concerted effort in the given setting’.

1.3 Property rights and resource management

The role of property rights in natural resources is crucial and it means that PRs can either

exacerbate or correct market failures. Open access, which results from generally ill-defined

property rights over natural resources, creates incentives for the depletion and deterioration of

common pool resources such as fishing grounds, pastures, timber stands and water sources. This

is a clear example of market failure where the citizens are encouraged to utilize resources to the

extremes and not save them for future usage. The failure of markets to coordinate their activities

is a crucial policy problem and institutionalizing property rights helps to address this

problem. Granting quotas or territorial use rights for resources, when legal, frees the user to

make long-term decisions. Territorial use rights in fisheries are a prime example – giving local

users exclusive rights of access and withdrawal to certain areas has led to the formation of self-

P a g e | 28

organization systems that employ traditional knowledge of fisheries and sustainable use and

conservation of resources. Despite the potential of property rights, increases in the number of

controversies that can be solved also indicate that there are difficulties in setting proper

boundaries and avoiding the capture of localized opportunities for elites. The same problems

have arisen in the decentralization of powers to local user groups of the forests. Titling can also

facilitate the setting up of property rights markets such us markets in tradeable permits or quotas,

which in turn utilizes market mechanism to transfer rights to more valuable uses. Therefore,

whenever rights are well-defined and enforceable, markets generate Pareto improvements to

allocative efficiency. However, the efficiency of these market-based solutions is questionable due

to issues of equity and fairness, transaction costs and environmental impacts especially for

regulating commons in the public domain. In summary, the definition and allocation of resource

property rights are essential from an efficiency point of view in implementing market

adjustments to correct market failures as well as from an equity and sustainable development

viewpoint in liberating and protecting the rights of vulnerable rights’ bearer.

1.4 Pigouvian taxes and subsidies

Pigouvian taxes and subsidies are applied via the market mechanisms, which are the policy tools

employed under market conditions when there are situations of market failure in relation to an

externality. In fact, externalities can be beneficial or detrimental depending with the

circumstances. This is a situation where an activity produces costs which have not been born by

the producer but are occasioned by the consumption of a good or by the operation of a business.

For instance, the pollution caused by factory industries creates externalities such as health and

environmental impacts which are not accounted for in the price system. Pigouvian taxes

introduce an economic price on negative externalities by setting taxes on the output that creates

P a g e | 29

them hence making consumers pay a price which reflects the true social cost. An example is the

use of fiscal measures such as charging industries for the carbon dioxide emissions they release

to the atmosphere, thus increasing the cost of polluting. Externalities are positive when there is a

net gain for the entire society but embedded in the market transaction, such as education results

in a skilled workforce is a positive externality since it benefits the entire economy. Subsidies are

the Pigouvian mechanism opposite to make consumers pay a price that makes them aware of the

social benefit. For instance, subsidies on tuition fees can be employed so that there are reasons

for individuals to obtain education despite their inability to perceive future private benefits. Thus,

such imperfection can be achieved through various ways such as subsidies on tuition fees so that

there is a rationale for people to gain education despite failure to consider future private benefits.

When set at the right level, Pigouvian taxes or subsidies can bring the consumer and producers to

bear the cost of the externality in their decision-making, thus rectifying the market fail. As for the

application of Pigouvian taxes in natural resource management we can state that there are always

significant external negative effects related to pollution or overconsumption and thus the use of

Pigouvian taxes, it is possible to apply them to the use of fertilizers, pesticides, water, or carbon

emissions. On the other hand, there could be subsidy worthy activities which include sustainable

or regenerative practices since they may have positive externalities on biodiversity and

ecosystem services. It is here that, some externalities have to be properly measured so as to shape

adequate Pigouvian instruments. When set rightly, they encourage the efficient and sustainable

use of available resources in the economic market.

1.5 Cap-and-trade systems for resource management

Cap-and-trade systems have now become well accepted as one of the most widely used market

based policy instruments in managing resource and overcoming market failures due to existence

P a g e | 30

of externalities. In cap-and-trade systems, an overall limit is established which defines the

amount of emissions or resource extraction allowed and permits which permit a fixed amount of

emissions or extraction which is then distributed to firms often through an auctioning

system. These permits can be exchanged among various companies, which develops market

prices for the rights to exploit resources or pollute. While other policies like command-and-

control prescribe the manner in which firms should implement pollution control measures, cap-

and-trade enables firms to implement CO2 cuts in a way that complements their overall limits

and exploit the varying marginal abatement costs of firms. An overall cap ensures that total

emission or extraction stays restricted to socially acceptable levels that would reflect external

costs. The trading market discourages firms from carrying out abatement measures to the level at

which the cost of their abatement equals the price of market permits. One would expect the firms

with lower marginal cost to reduce more emissions than the required, buy excess permits from

those with high costs. Through this, investors and innovations are encouraged and the price

transparency within the liquid market supports the reduction of abatement costs in the longer

run. Key use of this system has been implemented in cutting out sulfur dioxide and nitrous oxide,

limiting catch sizes in fisheries and is currently being used in controlling carbon emissions.

Some of the issues which must be addressed during the design process include determining the

cap level, the initial distribution of the permits, how to control for the price fluctuation, and how

to ensure compliance as well as preventing cheating. Well designed, cap-and-trade can lead to

decreased total compliance costs, accommodate industry needs and provide society with

environmental resource management. Concerns are more political and administrative where

concerns are based on the ability to implement the policy, legal requirements which need to be

P a g e | 31

met and distributional impact especially where the permit allocation favors some firms and not

others.

1.6 International agreements and transboundary resources

The cooperative international agreements and the management of transboundary natural

resources may be required when the action by a country affects the environment or the economy

of other countries. For instance, polluted water which affects fish stocks that are used in fishing,

are a negative externality that one country upstream imposes on another downstream country.

This often results in such things as political hostility or even outright wars between nations

where no cooperative arrangements have been made. International agreements were to

internalize these externalities and coordinate international incentives. Several policy tools which

may be applied in relation with the management of ICRs and trans-boundary externalities

include bilateral or multilateral agreements, establishment of transnational management

institutions/authorities and tradable permits. One is the use of cooperatives, for example, the ones

that may be established to regulate international water bodies or forest resources, setting the limit

of extraction, policies on pollution and so on Tradeable permits have also developed into one of

the most common market instruments where the rights for carbon emissions, fishing, among

other privileges, are bought and sold across countries encouraging the most efficient use of

resources. They also involve mechanisms of financial transfers between countries to restore

symmetry of costs and benefits in cooperative agreements. However, theories like collaborative

agreement have some issues which includes; the monitoring and enforcement of the agreement,

the fact that countries often act in their best interest while in the process of cooperation, and

equitable sharing of cost and benefits between nations. Another challenge is that negotiations

take place between countries, and, therefore, there are issues of power imbalances that can affect

P a g e | 32

negotiations. However, in international forums one can achieve repeated interactions over time

that help in building the institution’s credibility and trust for better policies. In summary, as the

world becomes more interconnected, managing the commons dilemmas entails policy tools that

can coordinate or incentivize action across borders, despite the fact that sovereign nations

generally have conflicting and self-interested policies.
