Globalization in a Balinese produce market

The summer before last, I spent three weeks exploring the mountains, beaches, volcanoes and temples of the Indonesian island of Bali. While crossing Bali’s central mountain range, I stopped at a produce market where local fruits, vegetables, coffee and nuts were brought in from the surrounding hills to be sold. As I strolled the market snapping pictures, I caught out of the corner of my eye a flash of a familiar shade of red. Upon closer inspection, I was surprised to find a “Blue Chelan” apple from Washington state (my home state!).

Washington apples in BaliI could not help but be shocked to see a fresh red apple grown on another continent in another hemisphere on the Eastern slopes of the Cascade mountain range of Washington state for sale in a farmer’s market in a remote village 60 km from the nearest port. It got me thinking about globalization, trade, specialization and comparative advantage. So I pose these questions to you, my Econ students:

Discussion Questions:

  1. How did a ripe apple grown 9,000 miles away in the United States end up fresh and shiny in a market 1500 meters up in the mountains of Bali? I mean, literally, HOW did it get there?
  2. Why would Indonesia import apples from so far away when surely it could grow apples domestically and avoid the hassle of transoceanic transport?
  3. Where did Indonesians get the dollars to buy US grown apples?
  4. How does trade between Indonesia and the US affect consumers? Producers? Is trade between these distant countries good or bad? Discuss.

Trade, Energy and Addiction to Foreign Oil

PickensPlan

The Pickens Plan is an initiative put together by the hedge fund manager of BP capital Management T Boone Pickens. The plan puts forth a model to get America off its addiction to foreign oil and on a path towards sustainable energy sources produced in the US of A. Watch the following video and read through the following information and comment on the questions.

“America is addicted to foreign oil. It’s an addiction that threatens our economy, our environment and our national security. It touches every part of our daily lives and ties our hands as a nation and a people. In 1970, we imported 24% of our oil. Today it’s nearly 70% and growing.

As imports grow and world prices rise, the amount of money we send to foreign nations every year is soaring. At current oil prices, we will send $700 billion dollars out of the country this year alone — that’s four times the annual cost of the Iraq war. Projected over the next 10 years the cost will be $10 trillion — it will be the greatest transfer of wealth in the history of mankind.

America uses a lot of oil. Every day 85 million barrels of oil are produced around the world. And 21 million of those are used here in the United States. That’s 25% of the world’s oil demand. Used by just 4% of the world’s population. The simple truth is that cheap and easy oil is gone.”

THE PLAN

Discussion Quesitons

  1. Is Pickens correct in saying that America’s addiction to foreign oil is a problem? Be sure to use the concept of comparative advantage and specialization in your answer.
  2. If we assume it to be a problem, what solution would you recommend? Do you agree with Pickens?

The opportunity cost of pristine wilderness is…

Bush, Democrats point fingers over energy crisis – Jul. 12, 2008

…apparently just over $4.00 per gallon of gasoline; at least according to the article above:

With gasoline prices above $4 a gallon, Bush and his Republican allies think Americans are more willing to allow drilling offshore and in an Alaska wildlife refuge that environmentalists have fought successfully for decades to protect.

Nearly half the people surveyed by the Pew Research Center in late June said they now consider energy exploration and drilling more important than conservation, compared with a little over a third who felt that way only five months ago. The sharpest shift in attitude came among political liberals.

The travesty of Americans’ attitude in favor of drilling and against conservation is the shortsightedness of it. Regardless of how many millions of acres of wilderness the government opens to drilling, gas and energy prices will only continue to rise over the long-run as emerging market economies like China’s will continually drive demand for energy higher and higher as growth rates remain above 8%.

America, in the mean time, with the largest per capita levels of energy consumption in the world (and some of the lowest gas prices), turns its back on conservation just when it is needed most. The cost to the environment, society and the bounteous wildlife that inhabit the vast tracts of land and sea that Congress is considering opening to exploitation by energy companies will create a permanent scar in one of the most valuable (and simultaneously undervalued) resources, its wilderness.

As my summer vacation approaches its end and I begin to think about another year of teaching Economics in international schools, I find myself reflecting on what’s most important in the world: to me, to my home country, to my fellow Americans, to the kids I teach and the students I will teach 10, 20, 30 years from now. I spend my summers in one of the most beautiful parts of this great country, the Pacific Northwest, whereMy wife Liz, overlooking the Selkirk mountains of Northern Idaho despite over a century of logging, mining, hunting and trapping, beautiful wilderness still remains. Only 2% of America’s original forests remain standing today. Countless species of predator and prey have been wiped out. There are around 300 wolves running wild here in Idaho, and thousands of citizens here are campaigning for a hunting season that will threaten to wipe out that great species once again. Clearcuts dot the landscape, proposed mines threaten watersheds and the wild Bull trout, an endangered species in the lakes and streams of Northern Idaho. Bears are put to death when the stumble into our yards, yet we turn more and more of their habitat into housing tracts every year.

Conservation is on my mind, and the news from Washington saddens me today, as I read that Americans concern themselves less and less with what I consider this country’s greatest resource, its wilderness, when times get the slightest bit difficult economically. As I prepare for another year of teaching Economics, this year at a new school in a new country, one where conservation is of the utmost importance, I will think about ways to incorporate more of an environmental economics perspective into this blog and my own teaching. As I prepare to leave my home in the mountains of Northern Idaho once again, I will cherish what little wilderness remains in this beautiful country, and try to make as little impact as I can on an individual level towards the continued destruction and exploitation of nature that characterizes the path that Americans seem to be choosing in this time of economic hardship.

“Agflation”, conservation, and the loss of wildlands in America

How does a growing Chinese middle class threaten duck populations in the American Midwest? Here’s the story:

As Prices Rise, Farmers Spurn Conservation Program – New York Times

“You can’t pay me NOT to farm this land!”

This is the view being expressed by more and more American farmers today. Since 1985 the US government has paid hundreds of thousands of farmers around $50 per acre of land per year to NOT grow food. In other words, if you were a farmer with 1,000 acres, you could earn $50,000 a year for not doing anything with it at all, just letting it sit idle.

What is the logic of such a program? In the mid-80′s food prices were so low that farmers working their tails off to cultivate and harvest their lands often found themselves losing money when they went to sell their crops. The traditional farming lifestyle was in jeopardy as farmers experienced year after year of economic losses. Improvements in farm equipment, along with the widespread use of chemical fertilizers, pesticides and herbicides had increased farm yields to levels never before achievable in human history. What increases productivity for all farmers, however, also increases total supply of crops, driving prices to historic lows. All this meant farmers could barely get by in the American heartland.

Enter the government:

…the Conservation Reserve was conceived as part of the 1985 Farm Bill. Participants bid to put their land in the program during special sign-ups, with the government selecting the acres most at risk environmentally. Average annual payments are $51 an acre. Contracts run for at least a decade and are nearly impossible to break — not that anyone wanted to until recently.

Things were great for the farmers. Output fell as millions of acres went into disuse, while farm incomes rose due to rising prices for their outputs and transfer payments from the American taxpayers. Farmers now had to work less to earn more money.

Today, however, farmers are putting millions of idle acres back into cultivation. They are choosing to work harder and farm more land in order to take advantage of the rising world food prices caused by the increasing demand for meat among the world’s emerging middle class and the rising price of grains due to the push to promote ethanol as a renewable energy.

The farmers’ behavior today is a perfect demonstration of the law of supply, which acknowledges the direct relationship between a product’s price and the quantity that producers will bring to market. There are actually two markets at work here: the market for cropland, and the market for wildlands. Farmers face a tradeoff in their decision of whether to farm their land or let it lay fallow. In 1985, the government made the decision that not enough land was lain fallow, so it subsidized farmers who set lands aside for conservation. Since subsidies are a determinant of supply, the supply of idle land increased while the supply of cultivated land decreased, driving up food prices.

In addition to the law of supply, this article also encompasses the concept of market failure. The Farm Bill of 1985 inadvertently corrected a market failure relating to “merit goods”, or those that create positive externalities or spillover benefits for society. In the case of farmland, the less land was used for farming, the healthier the wildlife populations on the now idle lands of the American Midwest. Hunters, environmentalists, and conservation groups had much to cheer about:

,,,hunters had more land to roam and more wildlife to seek out, with the Agriculture Department estimating that the duck population alone rose by two million; and environmentalists were pleased, too. No one disputes that there are real environmental benefits from the program, especially on land most prone to erosion.

At its peak the “Conservation Reserve”, as it was known, saw more than 36 million acres set aside for wildlife. Today, however, farmers are choosing to put this land back into cultivation.

Markets are complicated things. Markets do a fantastic job of assigning values to easily tradeable commodities like corn, soybeans, sunflower seed oil, and wheat, which happen to be some of the crops most commonly grown on the millions of acres set aside for conservation since 1985. What market fail to do, however, is to assign adequate values to the non-tradeable goods in our society. The biodiversity of a wild grassland, the health of a water fowl population, the carbon-sequestration capacity of a standing forest, and the joy a hunter gets from roaming a fenceless wild land.

As food prices continue to rise in response to the shift towards bio-fuels and the growing demand for meat among developing countries’ consumers, there will be more and more pressure for farmers in the industrialized world to take their lands out of conservation and put them into cultivation. This is not only a rich world phenomenon either. In Brazil, farmers are responding to rising sugar prices by cutting down ever growing chunks of the Amazon, one of the world’s last great rainforests, sometimes called “earth’s lungs” because of its ability to trap carbon from the atmosphere.

If balance between conservation and cultivation is to be achieved, it requires a market system that puts a tangible, tradeable value on the sometimes intangible “goods” relating to the environment. For now, a short-term solution might be a new Farm Bill that offers farmers a more substantial payment for keeping lands idle. Such an interventionist approach may stem the loss of wild lands, but does little to address the bigger problem of market failure underlying the degradation of the world’s remaining natural environments.

Question: Why would a firm voluntarily tax its own customers?

Answer: Because sometimes it’s just the right thing to do.

Major British retailer Marks & Spencer will charge for plastic bags – International Herald Tribune

More and more firms and governments are seeing the merits of corrective taxes on plastic bags. British retailer Marks and Spencer will voluntarily begin “taxing” its customers who wish to use plastic bags:

Beginning May 6, food and clothing retailer Marks & Spencer says it will charge 5 pence (10 US cents, €0.07) per plastic bag.

Marks & Spencer says it hopes the charge will save 280 million bags per year, and income from bags that are sold will go to an environmental charity called Groundwork.

The company said Thursday that it has tested the idea in Northern Ireland and southwestern England, and says it cut bag use by 70 percent.

Now that’s good economics, right out of a principles text: tax the product whose overconsumption creates negative externalities for the environment, and use the revenue earned to support environmental projects in the community. Here’s to Marks and Spencer, a corporation with an environmental conscience!

Turning gray to blue – the alchemy of clean air in China

Published by under China,Energy,Environment

Beijing’s Olympic Quest: Turn Smoggy Sky Blue – New York Times

In ancient times alchemists exerted great energy trying to turn worthless metals into gold. Their endeavors proved to be in vain as science would later show that such alchemy was a fantasy.

In Beijing, similar endeavors are underway to turn the city’s gray sky to blue for the upcoming Olympic games in August of this year. In a city where 1,200 new cars and trucks appear on the road every day and where a massive construction boom has been underway for years, the sky remains thickened with particulate rich smog for over 100 days a year. The problem is, China has promised the world that during the month of August, when the world’s athletes congregate in the city for the Olympics, the skies would be clear and blue.

The solution to Beijing’s problem is obvious, yet impossible to achieve: halt new construction, ban automobiles, and shut down the factories surrounding Beijing. So how IS Beijing planning to deal with this challenge? Turns out they’re once again turning to alchemy, this time to turn gray to blue: Continue Reading »

An answer to Kevin Yeh’s excellent question about emissions monitoring…

Environmental Economics: From the Answer Desk: Monitoring Cap and Trade

Towards the end of our last Micro unit, which was on Market Failure, SAS AP Econ student asked a good question in a comment on my blog post “Reducing negative externalitites – the European market for carbon emissions”

I forwarded Kevin’s question to the two professors who write the blog Environmental Economics. Their response to Kevin’s question is in the link above. Here’s what was posted on their blog last week:

Reader Jason Welker received the following question from a high school student (Kevin Yeh):

“It’s very interesting how this whole marketing pollution rights works. In this way the “commons” in the tragedy of the commons becomes privatized, and companies are forced to take responsibility for their pollution which is being dumped into the atmosphere.I do have one question, though, and that is how does one regulate the amount of pollution a factory dispenses into the air? How can the government be sure that a firm is not violating the law by dumping more than its licensed amount?”

My question: Why do Jason’s high school students ask better questions than my PhD students?

Anyway, I’m getting ready for a lecture on the EPA’s Acid Rain Program and I happened across this answer…

“Emissions monitoring and reporting systems are critical components of a successful program. Since the Program’s inception in 1995, the emissions data – continuously monitored by sources, verified and recorded by EPA, and posted for public review on the Internet – has been among the most complete and accurate ever collected by EPA. Unlike traditional emissions limitation programs, the Acid Rain Program requires an accounting of each ton of emissions from each regulated unit to determine compliance. The Acid Rain Program requires units to install Continuous Emissions Monitoring Systems (CEMS) to continuously measure and record emissions. In order to ensure accurate emissions monitoring and reporting, regulations specify equipment certification procedures, periodic quality assurance and quality control procedures, record keeping and reporting, and procedures for filling in missing data periods. All affected units are required to report hourly emissions on a quarterly basis to EPA’s tracking system. EPA invests substantial time and resources into assuring that both the monitoring and reporting of emissions are occurring properly and efficiently. Conservative “missing data” procedures help ensure that emissions are never understated. Real-time electronic auditing by EPA helps to ensure that emissions data are accurate, consistent, and complete.”

There you have it, Kevin! Looks like SAS Econ students are asking better, more relevant questions that Economics PhD students! Ahh… you guys make me proud!

Behold the Nano – “the people’s car”

The Nano comes with its own moral dilemma. – By Anne Applebaum – Slate Magazine

Tata Motors of India recently launched the world’s cheapest automobile, the Nano.

“…meet the Nano, possibly the most significant new car of the decade. Small, cute, and snub-nosed, it fits four people and a duffel bag, has a single windshield wiper, travels at 60 mph, and it’s all yours for the princely sum of $2,500…”

Tata plans to build and sell 250,000 Nanos this year in India, spreading production to Africa, South America, and Southeast Asia. Clearly the company is targeting not the traditional auto markets of Europe and North America, rather the regions traditionally thought of as poor and thus not associated with auto sales.photo

What is the meaning of this “car for the masses”? At first glance, it looks like the perfect solution for bringing millions of the world’s poor (if not super-poor) closer to the dream of achieving a quality of life previously only accessible by the world’s middle class and rich. Great,  so what could possible be bad about fulfilling the dreams of so many of the world’s poor? The answer? Externalities

“Though the small Nano uses less gasoline than many larger cars, the enormous potential numbers could mean an equally enormous environmental impact. Since it will be a long time before Nano drivers will be able to afford the $20,000-plus hybrids now on the market, let alone a Honda FCX Clarity, the prototype experimental hydrogen car thought to be worth as much as $10 million apiece, that means an exponential rise in carbon emissions as well as other kinds of pollutants. The United Nations’ top climate scientist, Indian economist Rajendra Pachauri—chair of the Intergovernmental Panel on Climate Change, which shared the Nobel Peace Prize with Al Gore—has said he is already “having nightmares” about precisely this scenario.”

Herein lies the moral dilemma of the Nano: where does society’s desire to improve the lot of the world’s poor come into conflict with society’s desire to to improve the environment and minimize the impact global warming?

What do you think? Do the social benefits of a $2,500 car exceed the social costs it will likely impose? Does the Nano’s $2,500 price incorporate the full costs that its existence places on society and the environment? Should we jump for joy at the thought of millions upon millions of the world’s poor finally having access to the convenience of automobile transport? Or should we pause with uncertainty to contemplate the effect on the environment and the social costs that millions of cheap cars will impose on the world?

“Global warming is one GIANT market failure”

Matt Rothschild of Progressive Magazine concludes that global warming is one “giant market failure”, and argues that US president George W. Bush is making it too hard for regulators in the country that is the world’s largest emitter of greenhouse gases to impose limits on pollution.

Among the externalities caused by the emission of greenhouse gases that Rothschild points out:

  • Rising sea levels
  • Arctic free of ice
  • Draughts  in Africa

Discussion questions:

  1. Is Rothchild’s understanding of global warming as a market failure correct in an economic sense?
  2. Is imposing new “limits on pollution” the best way achieve a long-term reduction in the emission of greenhouse gases?
  3. What alternatives to direct government controls over firms’ emissions does the Bush administration have that may make use of “markets” to correct this “giant market failure”?

When more tax is good tax…

Greg Mankiw’s Blog: The Pigou Club Manifesto

Here’s a good question to bring up around the dinner table with mom and dad tonight: “When is more taxes good?” Most individuals in society despise taxes; what is it the cynics say? “The only things guaranteed in life are death and taxes.” Clearly, the thought of giving money to the government is as miserable for some as the thought of dying!

But when might more taxes be good taxes? The answer, as you may have guessed, has to do with the concept of negative externalities and the idea that a tax may be used to correct a market failure of too many resources being allocated towards a particular product. One such product towards which too many resources have been allocated in the last several decades is gasoline; that’s right petroleum gas, the life blood of our beloved automobiles, the symbols of our very freedom and prosperity we cherish so much. How do we know too many resources have gone towards the production of gasoline? Simple, there’s too much of it and it’s too cheap. Evidence? Just look around:

  • Congested roadsGas tax
  • Urban smog
  • Auto accident fatalities
  • Shortage of parking spaces in most cities
  • Noise pollution
  • Sprawling road systems that ugly the landscape
  • Global warming

All of the above ills in some way are the result of cheap gasoline. The market failure here is simple: too much gas has been produced and it sells for too cheaply, hence, lots of people drive lots of huge, gas-guzzling SUVs, trucks, vans, sports cars, luxury sedans, Hummers, and not enough small, economical, fuel-efficient automobiles that would put way less a strain on our urban and natural environments.

So what do we do now to fix this problem? Should be dismantle all the oil refineries, shut down the gas stations, and blow up the pipelines that facilitate the production of gasoline? Well, that would be one option, although it’s not ideal. Another might be to require that all auto makers achieve a certain level of fuel-efficiency among their automobiles. That’s what the US government has done by adopting the “Corporate Average Fuel Economy” (CAFE) standards. This sort of direct control creates market distortions of its own, however. One economist has said, “the CAFE standard was a failure and said it was like trying to fight obesity by requiring tailors to make only small-sized clothes”
