ENVIRONMENTAL ECONOMICS--EC3545-001
(for non-economics
majors)
Course Content
The study of environmental economics is interesting,
thought-provoking, and controversial. This is both a strength and a weakness;
the strength is that the inherently interesting nature of the subject matter
results in greater student interest and involvement than might be the case for
many of the other fields in economics. The weakness, however, is that the
emotionally-charged nature of the topic tends to lead to fuzzy thinking--indeed,
there is ample evidence that this problem is not unique to the academic setting;
many of the worst examples of government spending and legislation have stemmed
from perceptions of a "crisis," whether it is an energy crisis, a defense or
terrorist crisis, a health-care crisis, or whatever.
As
you will see, the economist views environmental problems, like most other
problems, as being "resource-allocation problems" (that is, are we allocating
our scarce resources in such a way as to get the best combination of
environmental goods and ordinary goods that we value). Another way to
express this is that economists deal with choices. If a problem is
not viewed as being a matter of choice, then it is a non-economic problem.
The preceding three sentences are far more important--and controversial to many
environmental studies majors!-- than they might seem at this point...you might
wish to read them again. To make a simple analogy, suppose you believe
(for religious or other moral reasons) that it is wrong to have sex prior to
marriage--for you this is not "a matter of choice;" it is not "something to
decide upon." Economists also have various beliefs, but in their
role as an economist, such issues are viewed as choices, something to decide
about--to decide about on the basis of benefits and costs (note, these benefits
and costs need not involve dollars!). Depending on our individual
beliefs, the costs may be high relative to benefits, or they may be low.
If, however, costs are higher than benefits, and we abstain from pre-marital
sex, we are doing so--from the economist's perspective--as a matter of choice
(informed by our moral and other beliefs). But, while the observed
behavior might look similar, this is quite different from arguing that there is
no choice for such decisions. A perhaps more pertinent example: some of
you recycle as much as you can because you believe it is the "right" thing to
do, independently of personal costs and benefits; others of you hardly recycle
at all feeling that the costs are greater than the benefits. This
seemingly simple point, combined with relentless brainwashing in favor of "the
environment" beginning--these days--in grade school, will appear over-and-over
throughout the course and makes environmental economics difficult to
understand or enjoy for some students. However, I'll do what I can to make
it enjoyable!
We begin with the application of basic
economic and philosophical concepts to an understanding of the environment. This
is followed by a relatively brief overview of environmental quality, of the
major pollutants, and of how both are characterized. This is to give us a common
environmental background. We then turn to an in-depth treatment of how an
understanding of economics can usefully guide the analysis of environmental
quality, subject to some philosophical issues already hinted at. With this as
background, it is possible to turn to a consideration of appropriate
environmental policy. The focus is on applications vital to a voting citizenry
and to those going on to work in any area of the environment. My ultimate
goal for each of you is to have you better understand (maybe even agree with!)
how environmental problems are perceived by decision-makers in the "real world,"
hence better understand the policy approaches--good and bad--made by those
decisionmakers.
Texts:
There is considerable difficulty in finding an appropriate text for this course--the reasons are many: 1) most "environmental" textbooks have too little economic content to be useful, 2) most "economic" texts have as prerequisites more economic theory than is required for this course, and 3) many books are overly mathematical for the more policy-oriented approach that I wish to pursue. I have adopted the following two books, in part because both are controversial, but to different groups:
1) Lomborg, Bjorn The Skeptical Environmentalist (Cambridge University
Press, Cambridge UK) 2001. (This book--hated by traditional
environmentalists--was very critically received in Nature, Science, and Scientific American, but
received favorable reviews in The Economist on 2/2/02, The Wall Street Journal, and other
places. I adopted it to offset the ubiquitous pro-environment C.U. bias),
and
Administrative Matters:
There will be two midterms (60%) and the final (40%). The test format is, effective with the Fall 2004 semester, multiple choice--because of ever-increasing class sizes at C.U. As a consequence, the historical sample tests on the web will be less closely related to what you will experience than is usual...this will gradually change over time as additional sample tests get administered and posted. I will calculate your course grade as the largest number arising from the following alternative calculated scores:
"Score 1": .3(1st Mid Grade) + .3(2nd Mid Grade) + .4(Final Grade)
"Score 2": .4(2nd Mid Grade) + .6(Final Grade)
"Score 3": .4(1st Mid Grade) + .6(Final Grade)
That is, you can mess up either midterm (or miss it--there are no makeups) without harming your grade--however, the final is fully comprehensive, so you will be responsible for the information from both midterms on that exam. I will let the top 5% of students, based on the first two midterms, out of the final, an incentive to really learn the material. The Comprehensive Final Exam is Tuesday December 14, 7:30am-10:00 A.M. in our classroom. Note that if you have three exams in a day, it is the third exam that university policy allows you to reschedule.

Approximate Course Outline (subject to change as the course progresses, pending book progress):
Week Topic
1,2 Overview and Introduction (The Market and When It Fails
to Give Us What We Want):
Introduction: "Doomsters" vs. "Boomsters" and
their views of natural resource and environmental trends; Logical matters of
rationality; ordinary goods and environmental goods; Supply and Demand.
Efficiency versus equity (yachts and E.Q.); MSB=D? MSC=S?; Use of $'s; "Values"
(what the market does and broader issues of whether human marginal
willingness-to-pay is "appropriate" even without external costs or benefits);
externalities; public goods (new--quite pro-environment--material here, not yet
in any book!); the role of property rights and enforcement (endangered species,
but also air, etc). The "missing market." It is in this
philosophical section of the course that the issues raised by Ackerman and
Heinzerling first appear, but they continue in later discussion of
valuation...of what it is that economists are trying to discover.
3 An Environmental Background (Local
Environmental Problems):
I will only briefly discuss the "state of the
world." I am assuming that you have been very much exposed to the Doomster
position (brainwashed?), so will have you read Lomborg here and as the course
proceeds. While I will not be testing in excruciating detail on the information
in Lomborg's book (partly because he has a very selective take on the extant
literature), I will want you to have a solid general sense of his arguments (you
do not need to believe them--I am most definitely not trying to
brainwash you!)
4 Overview of an Interdisciplinary Approach to
Environmental Analysis (5-Box Diagram)
Costs of policy and impact on
emissions; dispersion; benefits of policy (damage reduction); spatial
adaptations in policy; incidence of policy (who is helped and hurt?).
5,6 The Economic Theory of Environmental Quality
The consumer optimum (excess pollution in the uncontrolled case, due to
externalities); the firm optimum (excess pollution in the uncontrolled case, due
to externalities); the law of conservation of matter and energy and the
summation of (non-optimally large) individual emissions into the environmental
quality we all consume; "social welfare functions" and implications in the
environmental setting.
Midterm #1 will cover the preceding material.
7 Interdisciplinary Approach (Boxes 1 & 2)
Policy costs (add-on devices, input substitutions, spatial and temporal
modifications, and input/output bans; higher costs or reduced quantities of
other goods ultimately--TANSTAAFL, but some "no regrets" policies) and the
impact on discharges; going from discharges to environmental quality.
8 Interdisciplinary Approach (Box 3)
Three
approaches to benefit estimation: 1) referenda, 2) survey/experimental, and 3)
use of known relations between environmental and other goods. Sub-approaches of
the last: 3a) sum of specific damages, 3b) hedonic approaches, 3c) travel cost;
philosophical issues again--the "statistical value of life" (review "values" and
preferences over values--read Ackerman and Heinzerling discussion of this).
9 Interdisciplinary Approach (Boxes 4 & 5)
The spatial dimension in environmental policy; local, regional and global
damages. What are the equity implications of environmental policy as practiced
in the U.S.? Why the poor pay a higher percentage of income in environmental
cost and why the poor receive lower environmental benefits as a percentage of
income (i.e. env policy is regressive).
10,11 Benefit-Cost Analysis (certainty and uncertainty)
government
failure; Ben Franklin quote; consumer and producer surplus; four approaches to
project evaluation (and why "net present value" is to be preferred); B&C as
S&D in disguise. Multi-attribute analysis. The rationality of discounting
and the appropriate choice of discount rate (again some new material here, not
yet in books).
Midterm 2 will cover the material between that of Midterm 1 and here.
12 The Coase Theorem
Why there are not more
environmental problems than there are--the Coase theorem; applications to the
steel plant/laundry, to the reserve clause of baseball, and to water allocation.
13 International Trade and Environmental and Human
Rights Concerns
Benefits from trade, in terms of wealth gains, for all
countries (production possibility curve and S&D approaches).
Relationships between wealth and demand for environmental quality and labor
standards. History of U.S. Temporary problems. Potential for
more of everything, including environmental quality. Controversial trade
material that is very poorly understood by non-economists (and even some
economists!).
14 An Ecological Doomsday Model (optional...we
usually do not get to this material)
An ecosystem: rabbits and foxes
(simultaneous equations); An ecological background; The
biologist/environmentalist versus the economist: notions of assimilative
capacity, environmental damages may be "optimal" (i.e. externalities can be
internalized, but with remaining environmental damage), and the "downward
spiral" of ever-worsening condition of both the economic and
environmental systems! Relevance of the model and possible offsets.
15 Policy Analysis--What Does Economic Theory Suggest?
Criteria for evaluation of policy; Coase and moral suasion (decentralized
approaches); Command-and-control strategies (standards, required equipment);
Incentive-based approaches (taxes, subsidies, salable emission rights).
16 Actual U.S. Policy
Water pollution control
policies; Air pollution control policies; Toxic and Hazardous substance policy;
miscellaneous related issues. I find the historical policy material
somewhat boring, so it is not emphasized.
17 Miscellaneous Topics
International
environmental responsibility (foreign, alternative economic system, global);
baby certificates and pollution permits; thinking about the carrying capacity of
a wilderness area; fisheries economics and rain forest issues
18 Epilog--Do You Expect The Future To Be "Better"?
Alternative views of the future. Population and income growth--are they good
or bad? The "boomsters" versus the "doomsters"--and the Simon/Ehrlich bet;
intergenerational equity; summary and review
(Comprehensive Final Exam, Tuesday December 14, 7:30am-10:00 A.M. in our classroom--Good Luck!)
