Regulation of Natural Resources
Lecture 15

 

Natural Resources - Definition and Overview

 

1. Natural resources - two types

  • Exhaustible Resources
    • Consuming each unit of a resource today prevents the future consumption of the resource
    • Examples
      • Petroleum
      • Natural gas
      • Coal
    • Could include minerals and metals; however, some minerals and metals can be recycled
  • Renewable Resources
    • The natural resource grows overtime
      • Fishing stocks
      • Forests

2. Common property and open access resources

  • Private property - an owner controls a property and can exclude outsiders.
  • Common property- the property is held by a group of individuals and excludes those not in the group.
    • Group can exclude outsiders
  • Open access property is the absence of ownership
    • Cannot exclude public use of property
    • Also known as the Tragedy of the Commons.
    • People have less incentive to develop, improve, or maintain land, if others cannot be excluded from consuming it.
  • Examples
    • Over fishing in public waters
      • Fishermen catch too many fish, causing fish populations to decrease to such a level that hurts future fish catching.
    • Dumping wastes onto public lands or waters.

3. Mathusian - applies to natural resources

  • Mathus was a priest
  • If human population grows too quickly relative to the food supply,
    • Not enough food to feed the population
    • Part of the population dies
  • Mathus assumed that population grew geometrically and the food supply grows arithmetically
    • Did not include technology
  • Food shortages, disasters, and wars keep the population in check.
    • Why economics is called the dismal science.
  • Mathusian ideas are still here
    • World is running out of natural resources, like petroleum
    • Population Time Bomb
    • Global Warming
    • Pollution.

 

Exhaustible Resources

 

1. Hotelling's prices - resources prices continuously increase over time as the resource is depleted

  • Refer to graph below
  • Time period 0 (blue supply and demand functions)
    • Market price is P* and Q*
    • Society consumes some of the resource, causing less resources to be used the following year
  • Time period 1 (green supply function)
    • Supply decreases as less resources are available
      • Market price increases
      • Market quantity decreases
  • Time period 2 (red supply function)
    • Supply decreases again as more resources are depleted
      • Market price increases
      • Market quantity decreases
  • Price continually increases until all the resource is consumed.
  • Benefits
    • Hotelling's price places a value on the resource that is in the ground
      • Called "in situ" values
    • Society conserves more of the resource as the price increases
    • Firms accrue economic rents
      • Also called user costs,
      • Market price exceeds marginal costs (or P* > MC) over the life of the resource.
    • Government can tax this economic rent; substantial source of tax revenue
  • Empirical evidence is mixed concerning Hotelling's prices.

  • Hotelling's price ignores two factors
    1. Technological improvements cause resource (marginal) extraction costs to fall over time
      • A competitive industry passes the lower costs to the consumers as a lower price (Fishelson 1983; Solow 1974).
    2. Hotelling prices depend on the petroleum reserves being known and fixed.
      • Resource companies do not know the location of all reserves and deposits.
      • When resource prices are high, petroleum companies have a strong incentive to explore and drill for new reserves and deposits (Farzin 2001; Fishelson 1983; Morrison 1987)

2. Hubbert’s Life Cycle Hypothesis.

  • Applied to the petroleum industry
  • When the petroleum industry was young and expanding its infrastructure
    • Petroleum companies discovered and developed new large petroleum reserves
    • Market price decreases over time.
  • Discoveries become rarer and smaller, and petroleum depletion caused (marginal) extraction costs to increase
    • Supplies of petroleum decreased, causing market prices to increase
  • Petroleum prices and petroleum production should be parabola shaped.
    • The graph below is the U.S. petroleum production
  • Technological advances could extend the time paths
    • Hubbert underestimated the U.S. oil production peak by 10 years.
  • Hubbert's Hypothesis applies to other exhaustible resources

3. Backstop technology - one resource is a perfect substitute for another natural resource, but has a higher cost.

  • Market price has to increase to a high level
    • High price makes the alternative resource feasible.
    • The alternative resource may have higher extraction costs or requires expensive technology.
  • Example:
    • Petroleum from shale rock.
    • Firms crush and extract petroleum from shale, which is more expensive than pumping petroleum from wells.
  • Backstop technology has one requirement
    o The alternative resource has to be supplied to the market in sufficient quantities at the same price
    • perfectly elastic supply
  • Refer to graph below:
    • Market price and quantity are P* and Q*
    • Over time, the supply function continuously decreases as natural resource is depleted
      • Market price increases
      • Market quantity decreases
    • Once market price reaches PB
      • Market quantity become 0
      • Market switches to the backstop technology and away from the resource

Renewable Resources

 

Renewable resources - natural resources that could grow and replenish over time

  • Examples
    • Fisheries
    • Forests
  • Renewable resources have two features.
    • Resource amount is determined by the biological growth and harvest rates
    • Market structure influences how much resources are used.
      • Monopolies - higher prices and lower harvest rates
      • Competitive markets - lower prices and higher harvest rates
  • If renewable resource is open-access and has competitive market, then the resource will likely be over-harvested.
    • Forests become bare
    • Fish stocks become extinct
  • Policies
    1. Government creates property rights
      • Called individually transferable quota (ITQ)
        • Government sets the maximum harvest level
        • Government issues permits
        • Producers can sell or buy permits
      • Permit holders protect their property rights from poachers
      • Government monitors permit holders
      • Canada was successful in using ITQs for fishing and lobster stocks.
    2. Government could impose taxes or quotas
      • Quota - set a limit on amount of fish or trees harvested.
      • Producers cannot buy quotas
      • The quota applied to the whole market
        • Problem
        • Producers race to harvest much as possible
      • Taxes
        • Tax amount harvested
          • Tax decreases revenue; reducing amount harvested
        • Tax effort
          • Effort is number of man-hours; capital, etc.
          • Tax increases costs, reducing amount harvested
      • Taxes and quotas may be difficult to enforce

 

Resource Sustainability

 

Sustainability economics - ensuring future generations are no worse off than today’s generation.

  • Sustainability economics is an equity issue and not an efficiency issue
  • Example
    • Consuming all the world's petroleum today leaves no petroleum for future generations.
  • Ensuring the welfare of future generations will not be harmed.
  • Government should impose the following policies (from Daley - need reference)
    • The harvest rate of natural resources should be set lower than the growth rate, ensuring the natural resource grows over time.
    • Degradable pollution levels should be set below the assimilative capacity of the environment, ensuring pollution levels decrease over time.
      • If the pollution does not degrade, then the emission should be set close to zero.
    • For nonrenewable resources, the extraction should be divided into two streams:
      • Income stream is used for consumption
      • Investment stream is invested into renewable resource technologies that are substitutes for nonrenewable resources.
    • A society should minimize the use of natural resources and energy that are used in the economy.
