The economic benefits of bike commuting

I feel like I’ve been here before. Gas prices are rising, approaching $4 per gallon. American drivers are freaking out, demanding the government “does something” to halt rising fuel costs. The next thing you know, people start buying bikes and riding them to work. Just like that, Americans change their lifestyles, abandon their cars, and reinvent themselves as bike commuters!

The economics of this phenomenon barely requires explanation, but since this is an Economics teacher’s blog, I suppose I should explain it. A major determinant of the demand for a product is the price of related goods. In the US right now, fuel and cars are related goods; in economics terms, they are complementary goods. “You can’t have one without the other”. As gas prices rise, demand for driving cars begins to fall, since it becomes more costly to drive. The other good related to cars in this picture is a substitute mode of transportation, bicycles. The more expensive it becomes to drive a car, the greater the demand for bicycles.

Now, allow me to take my econ teacher hat off and put my avid cyclist hat (or helmet?) on. Bikes are way more than just a substitute for cars. The fact that every time gas prices approach $4 per gallon bicycle sales start to spike is bewildering to me. Do consumers really not know that riding a bike is always cheaper than driving a car? Why does it take slightly more expensive gas to motivate consumers to think about buying a bike?!

Okay, economist had back on now: You see, operating a car involves monetary costs that far exceed the price of gas. When I last had a car in the US, I paid nearly $200 per month in insurance (young males always pay the most), far exceeding my expenditures on fuel. In addition, there’s the fixed cost of the car itself, which once spent is a “sunk cost”, so should not affect an individual’s decision to drive or not to drive when the price of gas changes.

In addition to these explicit, monetary costs, however, there are also external, invisible costs of operating cars that make them an even less perfect substitutes for bicycles. More traffic on the roads, more accidents, more air and noise pollution, greenhouse gas emissions, environmental impact of the production and ultimate disposal of the car itself: these external costs are not even born by the driver when he or she decides to drive to work every day, rather they are born by society, taxpayers, and the environment.

My point is, making the decision to switch to commuting by bicycle should not require a 25% spike in fuel prices. The cost of filling your tank is in fact the least significant cost associated with driving a car when you look at the whole picture, and include not only those explicit, monetary costs paid by the driver, but include the external, social and environmental costs born by society as a whole.

Maybe I’m just on a bike high right now, since I got my new 29 inch wheeled fully two weeks ago and have ridden the 30 km round trip to work nearly every day since! Then again, maybe it really would make more economic, environmental, physical, spiritual and social sense if more people would park their cars and hop on a bike tomorrow morning!

Is bicycle transportation an “inferior good”?

This article was originally published on May 12, 2008. It is being re-published since it relates to our current units in AP and IB Economics.

The Associated Press: Gas prices knock bicycle sales, repairs into higher gear

Greg Mankiw has an ongoing series of posts linking to articles illustrating the impact that rising gas prices have had on demand in markets other than that of the automobile.

One of the determinants of demand for goods and services is the price of related goods and services. As gas prices rise, drivers tend to switch from automobiles to alternative forms of transportation. A few days ago I blogged about the switch from tractors to camels in India, one illustration of the relationship between the price of one good and demand for its substitutes. Mankiw has so far linked to articles about the impact of high gas prices on demand for bicycles, small cars and mass transit.

These three “goods” are all substitutes for the most common form of transport among Americans, the private automobile (often times a gas-guzzler in “the bigger the better” America). When the price of a good like personal vehicular transport increases (in this case due to the price of an input required in private cars, gasoline), the demand for a substitute good will increase.

In the case of bicycles, evidence indicates that just such a change in demand is already underway in America today:

Bicycle shops across the country are reporting strong sales so far this year, and more people are bringing in bikes that have been idled for years, he said.

“People are riding bicycles a lot more often, and it’s due to a mixture of things but escalating gas prices is one of them,” said Bill Nesper, spokesman for the Washington. D.C.-based League of American Bicyclists.

“We’re seeing a spike in the number of calls we’re getting from people wanting tips on bicycle commuting,” he said.

Interestingly, the increase in demand for bicycle travel in response to high gas prices might be even more pronounced due to America’s sluggish growth, 4% inflation and rising unemployment. Real wages have seen little gain in the last couple of years as growth has fallen close to zero while prices have continued to rise. It may be possible that a fall in real incomes in America has spurred new demand for bicycle transportation, which could be considered an inferior good, meaning that as household incomes fall, consumers demand more bicycles for transportation.

Since bicycles represent such a drastically cheaper method of transportation, high gas and food prices, a weak dollar, and falling real wages accompanying the economic slowdown have had a negative income effect on American consumers, leading to increases in demand for inferior goods such as bicycle transportation

That said, having worked in a bike shop myself for two years in college, I can say that most consumers looking at new bicycles are not doing so because of falling incomes. Quite the opposite, in fact, indicating that new bicycles are normal goods (those for which as income rises, demand rises). However, the article states that in addition to increases in new sales, “more people are bringing in bikes that have been idled for years”.

It may be that while new bicycles themselves are normal goods, bicycle transportation as a whole is an inferior good. The increase in demand for new bicycles could be explained by the substitution effect (as the price of motor vehicle transportation rises, its substitute, bicycle transport, becomes more attractive to consumers) and at the same time explained by the income effect too (as real incomes have fallen, demand for the bicycle transport has risen).

This phenomenon is an excellent illustration of how the income and substitution effects work in conjunction to explain the inverse relationship between price and quantity demanded for automobiles (the law of demand), as well as the concept of cross-price elasticity of demand between two substitute goods.

Discussion Questions:

  1. Both the price of substitute goods and income affect demand for a particular product. How have both the prices of substitutes for bikes and the income of bike consumers influenced the demand for bicycles in different ways?
  2. What is the definition of an “inferior good” in economics?Do you believe bicycle transportation is an “inferior good”?
  3. Are all bikes the same? Do you think demand for some bicycles responds differently to changes in income than demand for other bicycles?

Letting markets work: the Malaysia fuel subsidy goes bye bye

This article was originally published on June 9, 2008

Asia Sentinel – Malaysia cuts fuel subsidy

One of the recurring themes of this blog is the conflict between good politics and good economics. Most of the time in government, smart economic policy is sacrificed in order to achieve political favor with voters. Whether it’s price ceilings on petrol in China, Zimbabwe’s slashing of food prices, harmful import restrictions to benefit domestic producers, or the proposed suspension of gas taxes in a time when fuel conservation is really what’s needed, politicians often act in economically stupid ways to bolster or hang on to their popularity.

So when a government makes a bold move that is economically sound, it sometimes comes as a surprise, as in the case of the Malaysian government this week. The government in Kuala Lumpur has for years subsidized domestic fuel prices, which at under 2 Malaysian Ringit per liter have been the equivelant of roughly $2.40 US per gallon, far below the average price in the west. Drivers benefited from this subsidy, but were not forced to bear any of the burden of rising oil prices, nor had they any incentive to conserve or switch to more fuel efficient automobiles or alternative forms of transportation. The Malaysian government, on the other hand, has had to allocate more and more of its limited budget towards subsidizing petrol prices.

Well, as of yesterday, all price supports for petrol are cancelled, and the effect will be sweeping in the Malaysian economy:

The government announced Wednesday evening that petrol prices would rise by 78 sen (US24¢) at midnight — a 41 percent jump from RM1.92 per liter to RM2.70. That means those spending RM2,000 per month to fill the tanks of their BMWs will now be paying RM2,820. Regardless of income levels, it is likely most Malaysians will feel the pinch.

The subsidy would have cost the Malaysian government 56 billion ringit (around $17 billion) this year. With the money it will now save by ending the subsidy, the government will begin making public transport cheaper and more convenient for commuters who wish to avoid paying for the more expensive petrol to fuel their personal automobiles:

The government hopes to channel the savings into improving public transportation, as it promised many years and elections ago but with little to show. In Kuala Lumpur, despite having a light rail train service and monorail, public transportation is expensive and inconvenient. Worse, intercity travel is still being serviced by old and slow trains, and accident-prone buses.

Malaysia is not the only country taking measures to end government fuel-price supports:

Indonesia has hiked fuel prices by an average of 29 percent, saving about 34.5 trillion rupiah and kicking off a series of street demonstrations… Similarly, after slashing subsidies, Taiwan will distribute US$659 million to middle and low-income families. The latest to raise oil prices is India, whose government announced Wednesday that gasoline and diesel prices will increase by 10 percent.

As more and more countries allow the market mechanism to work, and in the short-run fuel prices rise with the price of oil, the chances are that the long-run equilibrium price of petrol will actually begin to fall.Price controls and subsidies distort market demand. In Malaysia, where a government subsidy kept the price consumers paid around 2 RM, the quantity demanded exceeded the free market quantity. With the removal of the subsidy, consumers will respond by driving less, reducing overall quantity demanded for petrol. As other Asian nations follow suit, global quantity demanded for petrol will decline, while higher prices incentivize producers to increase output. New prouction facilities will come online, just as drivers begin to find alternative ways to get to work, either through carpooling, public transportation, cycling or walking.

The combined effect of slowing increases in demand (or perhaps even a decline in demand if enough substitution of alternative forms of transportation takes place), and increases in supply as new production facilities come on line will be a stabilization and eventual fall in the price of oil.

The future fall in oil prices is explained in more detail here. Malaysia’s repealing of the fuel subsidy is one example of how markets work to restore equilibrium in a market such as that for oil today, where short-term bubbles always burst. $135 oil is probably not here to stay, if only the market is allowed to works its magic.

Discussion Questions:

  1. Why does a subsidy create disequilibrium in a product market like the petrol market in Malaysia?
  2. Give two examples of how consumers may respond to the 40% increase in petrol prices once the subsidy is removed in Malaysia.
  3. How could making fuel more expensive to consumers in the short-run actually lead to a fall in oil and fuel prices in the long-run?

The questions no one seems to be asking about the auto industry bailout!

FT.com | The Economists’ Forum | Will Americans demand the cars that Congress wants the big three to build?

It’s been driving me nuts, this whole bailout debate. My frustrations are definitely appartent to my students, who have had to put up with my occasional rants about the insanity of the whole affair since the issue came to the media forefront over a month ago. Here are some of the issues that just don’t add up from the perspective of a high school economics teacher:

The three companies asking for a bridge-loan supposedly want the money so that hundreds of thousands (some reports say as many as 2.6 million) jobs can be saved. But how could Ford, Chrystler and GM possibly maintain their labor force in a time of a recession when nobody is buying new cars in the first place? In the parlance of AP or IB Economics, automobiles are normal goods, ones for which demand falls as incomes fall. By definition, a recession in the United States means falling incomes. A government loan may allow the Big Three thttp://hybridfueltech.com/media/cartoon.jpgo keep making cars for the time being, but WHY WOULD THEY KEEP MAKING CARS when falling incomes point to falling demand in the immediate future? Making cars that nobody will buy represents a gross misallocation of the nation’s productive resources, not to mention taxpayers’ money. What is required of these industries is precisely what the government loan will prevent them from doing, DOWNSIZING, meaning the shrinking of their labor force as well as the number of plants in operation.

The US recession can not be avoided by allocating the nation’s scarce resources towards a bailout of the auto industry. In fact, it will be worsened because the capacity of any nation to emerge from a cyclical downturn requires the flexibility of the country’s labor force to adapt to the structural changes the country is experiencing in the era of globalization and free trade. America’s future does not reside in labor-intensive manufactured goods, especially in the production of a very expensive durable good for which demand falls drastically during recessions; specifically, automobiles.

The Finanacial Times Economists Forum approaches the issue of long-term falling demand for automobiles from another perspective. One of the conditions of the Big Three accepting a loan from the federal government is the mandate that Detroit will begin producing more fuel efficient automobiles to assure Americans more affordable, more environmentally friendly alternatives to the gas-guzzling SUVs that have dominated the industry for the last two decades. But here’s the problem, gasoline has fallen to a price as low as it was when SUVs were at their peak popularity back in the early 2000s! As any high school economics student knows, gasoline and SUVs are what we call complementary goods, or two goods for which demand and price are inversely related. As gas prices fall to their 2000 levels, demand for SUVs promises to rise once again, while demand for fuel-efficient automobiles will likely decline, creating market pressures for the Big Three to make not more fuel-efficient cars, but more SUVs instead! From the Financial Times:

The basic problem is that Americans like to drive sport-utility vehicles, minivans and small trucks when gasoline costs $1.50 a gallon…

Consumers may have regretted their behaviour when gasoline prices soared above $4 a gallon, but as gas prices descend, there is no reason to believe that left unchecked they will not return to their gas-guzzling ways.

Indeed, there is a distinct possibility that if they really do increase their small car production, in a few years the big three will be back asking for more help, on the grounds that they are losing money by doing exactly what Congress asked.

The only reasonable solution to this dilemma? If Congress DOES begin mandating that Detroit increase its production of fuel-efficient cars and phase out its manufacture of SUVs, any such requirement should be accompanied by a government-set price floor on gasoline. Several months ago, my colleague and fellow blogger Steve Latter blogged about a proposed price floor of $4 per gallon on gasoline. Such a scheme would likely prove nearly impossible to initiate politcally, but may be exactly what’s necessary to add legitimacy to any government requiremens of Detroit to manufacture fuel efficient automobiles. The FT appears to support such a scheme:

Congress should put their mouths where their money is. They should make binding commitments to ensure higher US oil prices and thereby sufficient demand for fuel-efficient cars and trucks in the future.

Discussion Questions:

  1. What message does falling demand in the auto market send from buyers to sellers, and what contradictory message does a subsidy from the government send to auto makers?
  2. If the auto makers receive a low-interest bridge loan (subsidy) from the government, how will this actually undermine the efficient functioning of markets in America?
  3. Why would a price floor on gasoline be needed to accompany a government requirement that the Big Three make more fuel efficient automobiles after receiving a government loan?

$8-a-gallon gas: A New Perspective

Eight reasons you’ll rejoice when we hit $8-a-gallon gasoline – MarketWatch – by Chris Plummer

I selected this article because I really believe in it. It wasn’t until I became a fan of studying economics that I began to believe that rising gas prices are in the LONG TERM ECONOMIC INTEREST of the US economy as these higher prices will incent consumers and businesses to move towards alternate forms of fuels.

I am also no longer in support of US offshore drilling, not because I am an environmentalist, but an economist that understands that it will be necessary to take higher, painful increases in petroleum to incent businesses and consumers to pursue alternative energy and more efficient transportation solutions. Voluntary conservation or asking oil companies to pursue alternative fuel development is nice in concept, but poor in results.

I now root for “steadily climbing oils prices” to provide greater incentive to move faster to more efficient forms of transportation and spawn alternative energy solutions. It’s a little like going to the dentist: it’s not fun, but it is necessary and will leave us in better condition when its over.

For one of the nastiest substances on earth, crude oil has an amazing grip on the globe. We all know the stuff’s poison, yet we’re as dependent on it as our air and water supplies — which, of course, is what oil is poisoning.

Shouldn’t we be technologically advanced enough here in the 21st Century to quit siphoning off the pus of the Earth? Regardless whether you believe global warming is threatening the planet’s future, you must admit crude is passé.

Americans should be celebrating rather than shuddering over the arrival of $4-a-gallon gasoline. We lived on cheap gas too long, failed to innovate and now face the consequences of competing for a finite resource amid fast-expanding global demand.

A further price rise as in Europe to $8 a gallon — or $200 and more to fill a large SUV’s tank — would be a catalyst for economic, political and social change of profound national and global impact. We could face an economic squeeze, but it would be the pain before the gain.

The U.S. economy absorbed a tripling in gas prices in the last six years without falling into recession, at least through March. Ravenous demand from China and India could see prices further double in the next few years — and jumpstart the overdue process of weaning ourselves off fossil fuels.
Consider the world of good that would come of pricing crude oil and gasoline at levels that would strain our finances as much as they’re straining international relations and the planet’s long-term health:

1. RIP for the internal-combustion engine

They may contain computer chips, but the power source for today’s cars is little different than that which drove the first Model T 100 years ago. That we’re still harnessed to this antiquated technology is testament to Big Oil’s influence in Washington and success in squelching advances in fuel efficiency and alternative energy.

Given our achievement in getting a giant mainframe’s computing power into a handheld device in just a few decades, we should be able to do likewise with these dirty, little rolling power plants that served us well but are overdue for the scrap heap of history.

2. Economic stimulus

Necessity being the mother of invention, $8 gas would trigger all manner of investment sure to lead to groundbreaking advances. Job creation wouldn’t be limited to research labs; it would rapidly spill over into lucrative manufacturing jobs that could help restore America’s industrial base and make us a world leader in a critical realm.

The most groundbreaking discoveries might still be 25 or more years off, but we won’t see massive public and corporate funding of research initiatives until escalating oil costs threaten our national security and global stability — a time that’s fast approaching.

3. Wither the Middle East’s clout

This region that’s contributed little to modern civilization exercises inordinate sway over the world because of its one significant contribution — crude extraction. Aside from ensuring Israel’s security, the U.S. would have virtually no strategic or business interest in this volatile, desolate region were it not for oil — and its radical element wouldn’t be able to demonize us as the exploiters of its people.

In the near term, breaking our dependence on Middle Eastern oil may well require the acceptance of drilling in the Alaskan wilderness — with the understanding that costly environmental protections could easily be built into the price of $8 gas.

4. Deflating oil potentates

On a similar note, Venezuela’s Hugo Chavez and Iran’s Mahmoud Ahmadinejad recently gained a platform on the world stage because of their nations’ sudden oil wealth. Without it, they would face the difficult task of building fair and just economies and societies on some other basis.
How far would their message resonate — and how long would they even stay in power — if they were unable to buy off the temporary allegiance of their people with vast oil revenues?

5. Mass-transit development

Anyone accustomed to taking mass transit to work knows the joy of a car-free commute. Yet there have been few major additions or improvements to our mass-transit systems in the last 30 years because cheap gas kept us in our cars.

Confronted with $8 gas, millions of Americans would board buses, trains, ferries and bicycles and minimize the pollution, congestion and anxiety spawned by rush-hour traffic jams. More convenient routes and scheduling would accomplish that.

6. An antidote to sprawl

The recent housing boom sparked further development of antiseptic, strip-mall communities in distant outlying areas. Making 100-mile-plus roundtrip commutes costlier will spur construction of more space-efficient housing closer to city centers, including cluster developments to accommodate the millions of baby boomers who will no longer need their big empty-nest suburban homes.

Sure, there’s plenty of land left to develop across our fruited plains, but building more housing around city and town centers will enhance the sense of community lacking in cookie-cutter developments slapped up in the hinterlands.

7. Restoration of financial discipline

Far too many Americans live beyond their means and nowhere is that more apparent than with our car payments. Enabled by eager lenders, many middle-income families carry two monthly payments of $400 or more on $20,000-plus vehicles that consume upwards of $15,000 of their annual take-home pay factoring in insurance, maintenance and gas.

The sting of forking over $100 per fill-up would force all of us to look hard at how much of our precious income we blow on a transport vehicle that sits idle most of the time, and spur demand for the less-costly and more fuel-efficient small sedans and hatchbacks that Europeans have been driving for decades.

8. Easing global tensions

Unfortunately, we human beings aren’t so far evolved that we won’t resort to annihilating each other over energy resources. The existence of weapons of mass destruction aside, the present Iraq War could be the first of many sparked by competition for oil supplies.

Steep prices will not only chill demand in the U.S., they will more importantly slow China and India’s headlong rush to make the same mistakes we did in rapidly industrializing — like selling $2,500 Tata cars to countless millions of Indians with little concern for the environmental consequences. If we succeed in developing viable energy alternatives, they could be a key export in helping us improve our balance of trade with consumer-goods producers.

Additional considerations

Weaning ourselves off crude will hopefully be the crowning achievement that marks the progress of humankind in the 21st Century. With it may come development of oil-free products to replace the chemicals, pharmaceuticals, plastics, fertilizers and pesticides that now consume 16% of the world’s crude-oil output and are likely culprits in fast-rising cancer rates.

By its very definition, oil is crude. It’s time we develop more refined energy sources and that will not happen without a cost-driven shift in demand.

“Living” evidence of a determinant of demand at work in the deserts of Northern India

FT.com / Asia-Pacific / India – Camel demand soars in India

In a principles of economics course such as AP or IB Econ, we learn about the determinants of demand. I teach my students the acronym “TOEISS”, which stands for consumer tastes, other related goods’ prices, expectations, income, size of the market and special circumstances. A change in any of these determinants will shift the demand curve for a particular product.

“Other related goods” refers to the effect that a change in price for a substitute or a complement of one good will have on the demand for that good. An example might be the effect of an increase in the price of pork on demand for beef. Clearly, these two goods are substitutes in consumption, and if pork becomes pricey, consumers will demand more beef.

In an era of soaring gasoline prices, many consumers have made the switch from large, inefficient, gas-guzzling trucks and SUVs to smaller, more efficient hybrids and compact cars, a reasonable substitute for the average commuter. For some drivers, however, a hybrid just won’t meet their everyday needs.

In northern India, where farmers rely on tractors to till their arid fields, rising gas prices have made expensive tractors, dependent as they are on large inputs of fuel, less attractive to farmers. As gas prices have risen, demand patterns have shifted among farmers in the northern state of Rajasthan:

As the cost of running gas-guzzling tractors soars, even-toed ungulates are making a comeback, raising hopes that a fall in the population of the desert state’s signature animal can be reversed.

It’s excellent for the camel population if the price of oil continues to go up because demand for camels will also go up,” says Ilse Köhler-Rollefson of the League for Pastoral Peoples and Endogenous Livestock Development. “Two years ago, a camel cost little more than a goat, which is nothing. The price has since trebled…

”Market prices for these “ships of the desert”, which crashed with the growing affordability of motorised transport, are rising again as oil prices soar.

A sturdy male with a life expectancy of 60-80 years now fetches up to Rs40,000 ($973), compared to Rs5,000-Rs10,000 three years ago, according to Hanuwant Singh of the Lokhit Pashu-Palak Sansthan, a non-profit welfare organisation for livestock keepers. Entry-level tractors cost around $4,000.

Camels, the ultimate “alternative energy vehicle”. In fact, the only fuel these vehicles need is the occasional bite of grass and a weekly sip of water; talk about fuel economy!

While it may seem funny to those of us so used to the motor vehicle, animals represent a viable substitute for farm machinery in the developing world, and it is likely that as fuel costs continue to soar, more poor farmers will switch back to traditional means of tilling their soil. Water buffalo, cattle, camels, these are all substitutes for the gas powered tractor. Demand for these “alternative vehicles” will rise as fuel costs climb.

Discussion Questions:

  1. What is causing the demand for camels to increase in India?
  2. What will happen to demand for camels if the price of oil begins to fall again in the future? Explain.
  3. Do you think the camel is a viable “alternative energy vehicle”? What are the pros and cons of using a camel for farming compared to using a tractor for farming?

SAS Economists Podcast #6: The oligopolistic nature of the video game console market

by Annie Sung and Kristie Chung

Which do you prefer, the Wii? the XBox 360? the PS3? How about other video game consoles? Can you even think of any other video games consoles? Hmm… let’s see… how about the Sega? Wait, no, haven’t seen any of those in a while… what about the Atari? Oh, shoot, nope! Oh yeah, don’t forget the Caleco Vision (for the record, Mr. Welker’s earliest video game memory was of playing Smurfs on a Caleco Vision).

The fact is, today, the market for video game consoles has shrunk to three dominant firms: Nintendo, Microsoft and Sony. This podcast will investigate the video game console market, examine its characteristics, including the elasticity of demand for the different consoles, and conclude whether it exhibits the features of an oligopoly.

Supply and demand shifters and the price of pork in China

Vindy.com – Ethanol affects price of pork, China’s staple

What does the biofuel we put in our cars have to do with the meat we eat with our noodles and rice? Economics has an answer to this question! This week in AP Economics we learned that market supply of a product is determined not only by the price of the product but also by several “non-price determinants of supply”. To help remember these we learned an acronym:

S- subsidies and taxes
T- technology
O- other related goods prices
R- resource costs
E- expected future prices
S- size of the market (# of firms)

The article above talks about the relationship between the demand for ethanol, which is a corn-based biofuel being manufactured in record quantities all over the world, and the price of China’s staple protein source, pork.

Read the article, and discuss which determinants of supply are being affected, and describe the impact on the pork market (think of the supply and demand curves and equilibrium price).

Discussion Questions:

  1. As the price of pork goes up, what do you think is happening in the market for substitutes in consumption, such as chicken?
  2. How will the rising pork prices affect demand for chicken?
  3. Assuming that pork and chicken are also substitutes in production, how will the changes in the pork market affect the supply of chicken?
  4. What can we expect to happen to the price of other related goods as pork prices continue to rise?

Rough necks and rig hands: Wyoming’s booming gas industry

Natural gas in Wyoming | Boom and doom | Economist.com

From the latest Economist: an article about the booming natural gas industry in rural Wyoming (as if there’s such a thing as urban Wyoming) and the impact it’s having on the economy of one small town.

You’d think a booming industry offering high wages for low-skilled workers would be a godsend for a remote Western town like Pinedale, Wyoming. Think again; this article points out some of the downsides resulting from the natural gas boom since 2000, when oil shortages led to an increase in the price of gas and lots of new drilling in Wyoming, America’s least populated state.

Pinedale is at the centre of a Rocky Mountain gas boom that began in 2000 and accelerated five years later after Hurricane Katrina knocked out Gulf supplies, forcing up prices. On a mesa south of Pinedale, Wyoming’s busiest field is laced with dirt roads and pock-marked with well-heads and drilling rigs.

The influx of gas workers has increased the population of the area by 40% since 2000. The new business has meant more tax revenues for the county, “In 2001 Sublette county raised $16m in sales and other taxes. Last year it took in $53m.” What does all this mean for residents of Pinedale and the surrounding county? Higher wages and low unemployment.

Next year Pinedale’s school district will pay newly qualified teachers a base salary of $43,000—about the same as in Chicago.Teachers nonetheless earn less than rig hands, most of whom have no more than a high-school education. They are paid at least $49,000 plus overtime, according to a survey last year. The ready availability of well-paid work, albeit hard and dangerous, means that unemployment has almost disappeared (see chart). So have seasonal fluctuations. Jobs used to disappear when the snow fell. But the gas rigs now keep going through the winter.

The wage hikes enjoyed by government employees and gas workers, while good for some, means doom for local businesses not directly linked to the gas business, for whom the tight labor market makes it increasingly difficult to operate. The housing market has also experienced a shock since the gas boom, as properties away from the gas fields have barely increased or even decreased in value.

The interesting connection I see in this article to our Economics course lies in the affect of low unemployment and high wages on the business environment. See if you can identify the connection through the questions below.

Discussion Questions:

  1. What led to the increased drilling for natural gas in 2000? Which determinants of demand and supply led to the changes experienced in the oil and natural gas industries?
  2. What kind of labor market is the Wyoming gas industry most like, perfectly competitive or monopsonistic? How do you know?
  3. Are gas companies in Wyoming wage takers or wage makers? What’s the difference?
  4. If low unemployment and high wages are assumed to be good, then why does the article indicate that they are actually bad for some in Pinedale?
  5. Why has “the number of retail and entertainment outfits in Sublette county” fallen “even as disposable income soared”?

“Monster Hog” and the price of pork in China

National Geographic News Photo Gallery: Week in Photos: Monster Hog

Near Delta, Alabama, May 3, 2007—Hogzilla may be headed for horror-movie heaven, but the massive swine that became an Internet sensation in 2004 may have been bested, size wise, by this reportedly wild pig killed May 3 by Jamison Stone, 11, and reported by the Associated Press on Wednesday.

From tip to tail, the newfound hog—dubbed “Monster Pig”—measures 9 feet, 4 inches (284 centimeters) and weighs in at 1,051 pounds (477 kilograms), according to Stone’s father.

At a 150-acre (60-hectare), fenced hunting range, Stone said, he shot the huge beast eight times with a revolver before tracking it with his father and guides for three hours. Finally, the boy shot the hog at point-blank range, killing the animal, the AP reported.

While hunting by children is legal in Alabama, officials are investigating whether anyone had transported and released the live feral pig into the hunting preserve, which would violate state law.
