Environment and income
The relationship between income and the environment is an interesting topic to consider on many levels.
In terms of per capita income, we might associate higher income with higher concern for the environment for a couple of reasons. Countries with higher per capita income have already progressed through a long period of economic growth and development, have witnessed loss of environmental quality and may develop preferences for higher environmental quality. People may develop a sense of environmental awareness only after they've seen damage first hand. Further, "green" goods and services are often more expensive than goods that create more environmental harm. In short, wealthier households 1) may have a preference for and 2) can afford to buy organic products, solar panels and electric vehicles.
There is a lot of data that you could use to support these arguments, including time series analysis of polls addressing concern for the environment (note that the dips in the green line are highly correlated with recessionary periods. Also note the spike during the Deep Water Horizon spill), cross section analysis of spending on "green" products by income levels, or membership in environmental organizations by income levels.
In terms of aggregate income measures, economic growth tends to result in a structural shift away from activities that create a lot of pollution. In the initial stages of growth, economies tend to transition from the production of raw materials to agricultural products and then to manufacturing (all of which are relatively "dirty" endeavors). Once "developed", nations tend to outsource these activities to nations with lower wages (following the principle of comparative advantage) and focus production on services and high-tech activities which are relatively clean. We can look at growth in emissions, pollution or rates of deforestation to support these claims. Over the course of this semester, we've seen numerous examples of the association between high discount rates and overuse of natural resources.
The above two lines of thought provide support for the Environmental Kuznets Curve (EKC) hypothesis, which suggests an inverted u-shape relationship between pollution (on the vertical axis) and aggregate income (on the horizontal axis). Overall however, the evidence is mixed at best. There is little doubt that richer countries use significantly more energy and have higher ecological footprints on a per capita basis than poorer countries. Aside: Here is a fun little quiz to measure your ecological footprint. Mine is pretty bad (144 basketball courts, yikes!), largely due to a lot of international travel, two cars and a fairly large house.
Why does the relationship between income and the environment matter? What are some research questions that could be addressed on these topics? How might a better understanding of this relationship (at the household or national level) lead to better policy?

Incentives, Costa Rica and PES
One of the things we learn in natural resource
economics is to look at problems in terms of their costs and benefits. By
asking questions about who gains and who loses (and when, and how) we can
gain an important perspective on the causes of natural resource problems.
While it is certainly true that people behave in
ways that we can’t always predict, when given access to private benefits from
natural resources, people tend to take actions that promote their own
well-being. This access comes in the form of our daily contact with open access
and common property resources as well as extraction and habitat conversion on
private lands. Individually it does not feel like we’re doing much, but in the
aggregate our actions often have significant adverse effects on the
environment.
Yes, some people act in ways that benefit
the environment some of the time, but we all pollute in numerous ways to
promote our own benefits (comfort, convenience, standard of living), because it’s
cheap and easy to do so. As individuals, the costs we pay for access to the
world’s resources are low because they are shared by everyone.
How do we change the calculus? Let’s try everything and see what works. Education,
an appeal to “do the right thing”, and legal mandates on acceptable use, all
serve an important role. Monetary
incentives that affect household-level costs and benefits also can be an
effective tool in some situations. These incentives come in many forms, most of
which we discuss in this course.
One incentive-based method that seems to be
gaining favor in developing nations is PES. PES stands for Payments for Environmental
Services. The basic idea of PES is to create incentives for conservation of
natural resources by transferring dollars from those that benefit from
conservation to those who bear the (opportunity) costs of conservation.
In some PES arrangements government and/or NGOs
pay landowners to engage in activities to conserve or restore biodiversity.
This can be as simple as letting a cow pasture revert back to its natural state
or setting aside lands that would otherwise be used for another purpose.
Costa Rica is a leader in PES and a great example
of the power of this approach. From the 1940s through the 1980s, Costa Rica had
one of the highest rates of deforestation in the world. As recently as 1995, forest cover in Costa
Rica was as low as 25 percent of national territory, down from over 85 percent
in the early 1900s. The principle causes of deforestation were incentives for
the conversion of land to agricultural uses, such as preferable tax treatment
for lands used to cultivate crops and support cattle, and heavier tax burdens
for “unproductive” lands (i.e. lands not used to produce market benefits). People
responded to the incentives they faced. Given the costs and benefits of land
use it made sense to convert lands to other uses.
In 1996, leaders in Costa Rica decided to try to
reverse this path of biodiversity loss. The main idea was simple: reward
landowners for conservation rather than rewarding them for land conversion. A
series of forest laws were enacted, which gave favorable tax treatment to conservation
and reforestation, banned the export of primary forest products, mandated that
banks provide low-interest loans for reforestation, created a system of
national parks and forest reserves and, in 1997, enacted a PES system.
Costa Rica’s PES system involves direct payments
to landowners in exchange for the adoption of land uses and management
techniques that provide one or more of four services: Greenhouse gas mitigation, provision of water
or other hydrological services, conservation of biodiversity or provision of
scenic beauty for recreation and tourism. Payments are provided by government. Revenues
from a fuel tax (ala Pigou) are a primary source of funding. Other sources of
funds include sale
of carbon credits to other nations and international loans. Between 1997
and 2005, a half-million hectares of forest lands were enrolled in the program.
Forest cover is now over 60 percent and rising.
While this progress is exemplary, the Costa Rican
Minister of the Environment recently stated that it is getting increasingly
difficult to conserve. Without a
system of international carbon markets, such as that which might take place
through large scale adoption of REDD and
REDD+ schemes, he suggested that the Costa Rican path of conservation will
soon be unsustainable.

Costs and benefits of fracking
A new study in the journal Annual Review of Environment and Resources summarizes the environmental costs and benefits of fracking, based on a review of 165 academic research articles and databases. Read a summary here at Science Daily. The full article is available here.
The article highlights some important tradeoffs, and does a nice job dispelling some myths. Perhaps the most important point is that there is still a lot that we don't know about this controversial procedure.
What do we know? Fracking uses a lot of water, but the use of natural gas instead of coal, nuclear or ethanol saves a lot of water. Groundwater contamination is possible (and not as likely as you might think according to the study), but contamination of the air with C02 is decreased significantly.
Fracking will most certainly continue. A massive source of energy is not going to be ignored. Basic supply and demand tells us that this will delay the transition to renewables, perhaps for a long time. The principle questions are what to do with the waste water and whether research into the costs and benefits can take place at a rate that parallels the growing demand for cheap energy.

In the news part 3: SB 729
State Bill 729 is the Coal Ash Management Act of 2014, which calls for Duke Energy to remove or close all of its 33 coal ash dumps ("ponds") by 2029. The bill, currently making its way through the State Senate, also requires several "high risk" sites (including the local Sutton Lake site and the Dan River site) to be removed within 5 years. Intermediate-risk sites will have to be removed within 10 years and low-risk sites will have to be removed or "closed" within 15 years. "Closing" a coal ash dump means that the site is capped and left in place.
Duke Energy, the largest power company in the U.S, has suggested that they need 30 years to close or remove all the sites and that this will be a very expensive venture, given that there is roughly 100 million tons of coal ash to be dealt with across the state. The bill prohibits the costs from being passed to taxpayers, but leaves room for Duke to increase utility rates to offset the costs. I think we can all expect to pay more for electricity soon.
Environmental groups are saying that this is a step in the right direction, but it could still allow for pollution of ground water, given that all of Duke's14 power plants and all 33 coal ash ponds are located near rivers or lakes that supply drinking water to municipalities. The bill allows some coal ash to be stored in unlined landfills or stored on site.
Coal ash contains numerous toxins, including arsenic, selenium, chromium, lead and mercury. Selenium pollution from coal ash in Sutton Lake has been linked to fish deformities and premature mortality according to a study by Wake Forest University Professor Dennis Lemly. More on that story here. Note the economic values attributed to the fish loss, and the use of "replacement cost" values as an indicator of opportunity cost.
As many of your are aware, all of this action was prompted by a spill of 39,000 tons of coal ash and 27 millions of gallons of coal ash waste water into the Dan River in Eden NC in February of this year.
This could all get much more complicated in the coming months, because the EPA will issue new national coal ash standards in December 2014.

In the news part 2: Preservation via command-and-control
Related to the topic of land rents, last month the Obama administration proclaimed nearly a half-million acres of land in south-central New Mexico as a national monument. The area is called the Organ Mountains-Desert Peaks National Monument and will managed by the Bureau of Land Management as part of the US system of national conservation lands.
Read about it here at the Whitehouse.gov
Here is an editorial on the topic in the Tampa Tribune that also appeared in today's Wilmington paper
Related to topics this week, today, the Obama administration will announce the creation of the world's largest marine sanctuary. The Pacific Remote Islands Marine National Monument will protect 782,000 square miles (for perspective, that's about 3 times the size of Texas) from all human activity.

In the news, part 1
There has been a lot of environmental news lately.
At the national level, last week the White House unveiled a new plan to cut carbon emissions from power plants. The target for the emissions reductions is 30 percent below 2005 levels, but each state has its own target (performance standard) based on current emissions. Emissions from power plants are the largest single source of CO2 in the U.S., and most of the existing power plants are more than 40 years old. It's important to note that U.S. emissions have been declining since 2005, so some of the reductions have already been met.
This was interesting on a couple of levels. First, because of a 2007 Supreme Court ruling that gave the EPA authority to regulate CO2, coupled with a 2009 "endangerment finding" the President did not need approval of Congress for this new measure.
Second, the rules allow each state flexibility in terms of how they reach their target. States and power plants can use technology to directly reduce emissions (e.g. better scrubbers), they can covert coal plants to natural gas, they can subsidize or otherwise promote renewable energy sources, or they can engage in cap-and-trade systems. Combining a standard with this flexible approach should offset some of the efficiency loss, but we can probably expect energy prices to rise. However, the EPA suggests that the benefits will be 8-12 times greater than the costs. The benefits of the new rules are estimated to be between $55 and $93 billion, which includes avoiding thousands of premature deaths and over 100,000 asthma attacks per year, in addition to slowing climate change, enhancing agricultural productivity and reducing ecosystem and species loss.
Finally, one day after the announcement, China announced a plan to place a cap on CO2 emissions as part of its next 5-year plan.
Questions to consider:
Who is against the new regulations and why?
Who is in favor of the new regulations and why?
How will cap-and-trade work in this situation?
Will Pigouvian taxes or subsidies play a role?
What non-market costs and benefits might be affected?
What are the implications of China's announcement?
Objective responses please.

Reading articles is hard work!
The past two posts have provided links to additional readings on topics we're studying. Many of these readings are academic journal articles. As you get into these readings, one of the things you'll quickly learn is that reading
academic articles (about economics or environmental studies, or anything
else) is different than other types of reading. First, it's hard
work. You have to read slowly. You have to read everything at least
once, and some parts multiple times. You'll encounter language and
vocabulary and math that you don't understand (you'll have to look it
up). You have to take notes. Yes, this is a lot of trouble. But, if you
want to understand things deeply, this is the way to do it.
Real knowledge and understanding isn't going to land in your lap without hard work, and
you can't find it in a YouTube video. You have to
read, and then read more. Some of you may hide behind the "its too
boring" claim, justifying not reading by saying you're not interested in
the topic. I hope you don't fall into that trap, because honestly,
when you really understand something, it absolutely ceases to be
boring.
Dig in. Engage your brain. Read like crazy.
Here is a blog post on the topic of critical reading by Jennifer Raff, a research fellow at UT Austin and occasional cage fighter. She's in the natural sciences (using genetics to answer questions related to anthropology), but much of what she says is pertinent to all disciplines. Hat tip to NR for the link.

More valuation readings
As we get deeper into our discussion of non-market valuation, I'm going
to continue my efforts to convince you that economic analysis has a
indispensable place at the conservation policy table. This argument is
fairly easy to make when I'm talking to economists or economics
students, but for those that have never really studied econ before, it's
a bit tougher. This is because people who have only studied natural
sciences may have a tendency to view all things dealing with markets as
the causes of environmental problems rather than the solutions. I hope you're starting to see that it's both.

Valuation
This week we begin our study of valuation. Valuation means figuring out what something is worth, usually in dollars.
It is important to note that economic value involves much more than market transactions. People value things that are not traded in markets and people value things that they never use. Another important point is that economists don't just go around trying to place a value on things for no reason. We engage in valuation when understanding what something is worth can help inform the policy process. Any time there is a tradeoff involving environmental quantity or quality, valuation can serve an important role in terms of helping us understand what is at stake.
One situation where valuation is useful is in determining the monetary value of a fine or fee to impose on a responsible party in the case of natural resource damages. For example, BP will pay about $4.5 billion in criminal and civil penalties for the Deep Water Horizon spill. Transocean (the owner of the rig) will pay $1.4 billion.
What are some other scenarios where valuation might be useful for informing policy?
Interestingly, I sometimes encounter hostility when I first present the idea of valuation to people who have never been exposed to it. One line of reasoning is that valuation somehow "cheapens" the environment by expressing its worth in dollars and cents. My response to this objection is that the default value is typically zero. That is, most people treat the environment as if it were free, and you can't get much cheaper than that. Valuation often helps people realize that the environment is extremely valuable, despite it being available for "free".
Another thing to realize is that we are constantly engaging in valuation anyway, through our actions and choices. For example, when society chooses to spend a certain amount of money on highways, healthcare, and social security and NOT spend that money on environmental protection, are we not indirectly placing a value on the environment relative to those other things? On a micro level, when you choose to drive your car instead of walking, are you not revealing that you value your own convenience more than you value the environmental damage from your emissions?
Here are some links to more reading about valuation:

Standards vs. Incentives
As we move into discussion of correcting market failures, it’s
important to have different perspectives and examples. Below are some links to
excellent sources of information regarding standards (command and control) and
incentive-based systems.
Here
is some excellent reading from the US EPA on standards vs. incentives.
More detail is provided in this document (also from EPA. Note that Coase is covered on page 4-4).
Here is a nice paper on the topic from the World Resources Institute.

Here
is a link to a report on the use of economic incentives for pollution
control in the US. You can use the "quick links" on the right to
navigate the document.
Environmental Defense Fund has a short piece on how the use of incentives was a powerful solution to addressing acid rain.
The Environmental Literacy Council has a nice short article on standards vs. incentives.
Here's more from the World Bank.
Here is a short article on economic incentives for water quality management from the WHO.
Here is a great article by Robert Stavins on the topic.
Lots of great information in this report on Economic Incentives for Pollution Control from UNEP.

What are some success stories where economic incentives have
been used to reduce pollution?
If incentive-based systems are superior, why do we rely so heavily on standards?

Economics and the Environment
As students begin to study the discipline of natural
resource economics, there is often confusion about what the subject is about.
This is especially the case when students are coming from backgrounds with only
limited exposure to economics (e.g. EVS, where you've only had one or two econ
classes before this one).
Generally speaking, economists try to solve problems using a combination of theory, empirical analysis (data, statistics, math), and intuition. For example, macro economists try to address issues such as how to keep an economy growing without significant inflation. Micro economists might try to find the best way to maximize profit for a particular firm or industry. Natural resource economists try to solve problems associated with scarce natural resources.
Some examples from my work include: How to maximize fishery value while balancing the competing needs of commercial and recreational fishers and maintaining a biologically sustainable stock? How can Caribbean tourism grow without harming coral reef quality or marine turtle populations? How can tourism serve to enhance the livelihoods of local populations? What hunting regulations would maximize the net gains to society from white tailed deer populations? In the face of depleted stocks, will a nation's supply of seafood increase or decrease with financial incentives to curtail fishing effort? What are people willing to pay to view marine turtles in the wild? Will people pay for marine turtle conservation, even if they never see a turtle in the wild? How can these willingness to pay values be captured and used for conservation?
Obviously, these are complex issues that require interdisciplinary effort. One of the things that I really love about what I do is that I work side-by-side with biologists, policy makers and resource users to address these problems.

Something that should also be obvious is that these are contentious issues. It is easy to get caught up in the emotion that surrounds any debate about environmental issues. Please remember that an economists job is to provide objective analysis (i.e. no personal opinion or bias).
Here are links to two excellent essays that provide a nice perspective on the economic view of the environment.
The second essay covers non-market valuation, which we will
cover in detail later in the term. It makes a good read now however, as
it sets the stage for much of what we're covering at the beginning of the class
(e.g. the economic view of value).
