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
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 book, in part because it is extremely controversial (a fairly favorable review in The Economist on 2/2/02, but roundly trashed by Science, Nature, and Scientific American):
Lomborg, Bjorn The Skeptical Environmentalist (Cambridge University Press, Cambridge UK) 2001.
However, while Lomborg typically uses economic reasoning in making his arguments, class attendance will be quite important, far moreso than is usual at C.U. In large part, this is because I prefer an organization of the material that is not yet available in textbook form. I will be posting handouts to my website that will provide a detailed guide to lectures for the course. Getting notes, if you must miss a class, is still likely to be quite helpful, since the concepts in the handouts will be illustrated with numerous examples during class discussion. All notes are not created equal--if you must miss, get somebody's notes who is a good note-taker.
Administrative Matters:
There will be two midterms (60%) and the final (40%). The test format is a mixture of subjective (short-answer, space constrained, essays) and objective ("shotgun" T-F questions) questions and there are sample tests on the website.

Approximate Course Outline:
Week Topic
1,2 Overview and Introduction (The Market and When It Fails
to Give Us What We Want):
Doomsters vs. Boomsters and the natural resources
and environmental implications; Logical matters of rationality; ordinary goods
and environmental goods; 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."
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, 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 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).
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.
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
material that is very poorly understood by non-economists (and even some
economists!).
14 An Ecological Doomsday Model
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 (handout))
16 Actual U.S. Policy
Water pollution control
policies; Air pollution control policies; Toxic and Hazardous substance policy;
miscellaneous related issues
17 Miscellaneous Topics
International
environmental responsibility (foreign, alternative economic system, global);
baby certificates and pollution permits; 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
