Luxury goods: the biggest rip off in the world or the “must have items” for any self-respecting European?

TDeluxe: How Luxury Lost Its Luster – Dana Thomas – Books – Review – New York Times

Unit 2 in IB and AP Economics begins by examining the interaction of supply and demand in product markets, and the importance of these factors in determining the equilibrium price in any particular product market.

In the above article from the NY times, the author reviews a book that exposes the diminished quality and attention to detail among manufacturers of luxury goods (think Prada, Gucci, etc…) The era of globalization and off-shoring of manufacturing has aided luxury firms in their quest for profits, as they’ve been able to significantly cut costs while maintaining exorbitant prices for their product.

The author takes issue with the alleged demise in the luxury market of attention to detail and craftsmanship, as competition and profit seeking behavior have led to an industry where the back alley workshops of Milan and Paris have been replaced by the factory floors of China and Vietnam. Free trade has allowed European luxury brands to produce more of their products at lower costs, which leads the author to her current question: “Why is this stuff still so expensive even as the cost of producing it goes down?”

Despite her accusations of poor quality and greedy, profit seeking managers in the luxury goods industry, the author seem unable to resist the luxury goods she claims to despise:

When, I asked myself, did it become commonplace to charge several thousand dollars for a mass-produced handbag? How could the flimsy designer sundress I bought on sale (a “steal”, the saleswoman assured me) still wind up costing a whole month’s salary? Why is my favorite brand of lipstick more expensive than a nice bottle of Italian wine? When did these products’ values grow so distorted, and what is the would-be customer to make of it all?

The author continues…

the luxury industry is a sham because its offerings in no way merit the high price tags they command. Yet once upon a time, they most certainly did. In the 19th and early 20th centuries, when many of luxury’s founding fathers first set up shop, paying more money meant getting something truly exceptional. Dresses from Christian Dior, luggage from Louis Vuitton, jewelry from Cartier: in the golden period of luxury, these items carried prestige because of their superior craftsmanship and design. True, only the very privileged could afford them, but it was this exclusivity that gave them their cachet. Although they may have “cared about making a profit” the merchants who served this pampered class aimed chiefly to produce the finest products possible.

It appears that the author never took an introductory economics course. If she had, she would clearly understand that price is not determined by the level of craftsmanship, the attention to detail, nor the level of exclusivity represented by a particular purse, shoe or dress. Rather, price is determined by the interaction of Demand AND Supply in the market for all goods, EVEN luxury goods!

When she claims that “the merchents who served this pampered class aimed chiefly ‘to produce the finest products possible’”, the reviewer is forgetting some of the basic teachings of capitalism’s founding father. Adam Smith himself could have corrected the NYT reviewer when he said,

Whoever offers to another a bargain of any kind, proposes to do this. Give me that which I want, and you shall have this which you want, is the meaning of every such offer…

Smith knew as any economics student should know that exchanges in any market happen not because of a mutual appreciation for craftsmanship or artistry, rather because a producer (firm) wants to make a profit by charging as high a price possible to a consumer (household). In the case of luxury goods, Gucci and Prada never made high quality goods because they loved making high quality goods, rather they made them cause consumers demanded them and were willing to pay top dollar for them.

What the author is missing is a basic understanding of the determinants of Demand. The price a good commands in the market has little to do with how much it cost to produce or where it was produced, and everything to do with the level of demand relative to the level of supply.

Discussion questions:

  1. Why do Prada, Gucci, Cartier and other luxury brands command such high prices relative to cheaper substitutes widely available to consumers?
  2. As nothing else changes and the price of luxury goods goes up, how is demand affected? Explain.
  3. What are some of the determinants of demand that have kept the price of luxury brand goods high even as the costs of production have been reduced due to cheap overseas manufacturing?

Forget bonds, gold, stocks, or real estate; try investing in some Garlic!

Swine flu fear leads to shortage of garlic in China – Telegraph.

My colleague this morning happened to ask if I had heard about the garlic bubble in China. A quick news search led me to the story:

Garlic prices have increased fifteen fold in China in under a year because Chinese investors are said to be attempting to create an artificial shortage and drive up prices.

Chefs and housewives in some cities are struggling to get hold of one of the nation’s favourite ingredients, which has passed gold and oil to become the China’s best-performing asset.

Several factors have led to the “garlic bubble” in China. Firstly, low prices of garlic last year:

Falling garlic prices last year have contributed to the shortage with many farmers discouraged from planting the crop again…

To compound the problem, supplies of garlic have been further reduced due to speculation. Yes, speculators are hoarding warehouses full of garlic to drive price up in the face of rising demand. Chinese believe that garlic has medicinal properties and is therefore a remedy for swine flu. This year’s unusually high level of demand is attributable to the flu epidemic and Chinese desire to consume more garlic to fend off the illness.

The result of all these combined factors is illustrated below. The low prices in 2008 led to farmers to cut back on production, reducing supply to S2009normal. What the farmers did not predict, however, is the rise in demand due to swine flu. The reduced supply is exacerbated by speculators buying up output and warehousing it, shifting supply further left to S2009w/speculation.

As can be seen, prices have risen, but shortages persist. It should be expected, therefore, that prices will continue to rise until the shortages are eliminated. On the other hand, the speculators may begin to release their hoarded supplies, shifting supply outward and restoring equilibrium closer to the current price.

A third possibility is that the swine flu epidemic will subside and demand will return to a normal level. This, of course, would spell doom for speculators who put millions of RMB into garlic who would then find themselves with “assets” that had lost their value. This would mean the proverbial “bursting of the bubble”. This final possibility seems unlikely anytime soon, for among the Chinese, traditional beliefs run deep, and with the lack of widespread access to a swine flu vaccine, garlic will likely remain the remedy of choice for the country’s masses.

Looks like the Financial Times could use a high school economics lesson!

FT.com / MARKETS / Commodities – Shortages stir coffee and sugar prices

My favorite economics blog, Environmental Economics, points to an article from the Financial times that appears to make a very elementary mistake in its use of basic economics terminology. Read the excerpt and answer the questions that follow.

Shortages stir coffee and sugar prices
By Javier Blas and Jenny Wiggins in London
Published: May 10 2009

Caffeine addicts face higher prices for their daily fix as the wholesale cost of both coffee and sugar rise sharply because of poor crops and robust demand.

“We are in a dangerous situation,” Andrea Illy, chief executive of Italy’s leading coffee ­company, told the Financial Times, warning that prices could “explode” due to supply shortages.

Discussion Questions:

  1. Define “shortage”.
  2. Does the rising price of coffee indicate that there are shortages in the market? Why or why not?
  3. Would “poor crops and robust demand” necessarily combine to create a shortage of coffee? Why or why not?
  4. What would lead to a shortage of coffee, based on the economic definition of the term “shortage”.

Product differentiation in imperfectly competitive markets – the MacBook Wheel

In  IB Economics, we are currently learning about how firms in imperfectly competitive markets differentiate their products in order to increase their market power and their price-making power.

In a market with a few large firms such as the laptop computer market, companies must do what they can to increase demand for their own products over those of their competitors. Apple Computer is an example of a company that has successfully differentiated its line of laptop computers in recent years, regularly improving the features of its line of MacBooks to attract consumers away from its competitors and into the world of Macs.

Last year Apple launched the MacBook Air, the lightest and thinnest laptop on the market, creating a huge buzz in the technology world and converting millions to Apple’s line of laptops. This year, Apple has launched yet another innovation in laptop computing, in the hope of once again increasing demand for its products, and making consumers think they cannot live without the sleek, shiny Apple computers. This year’s innovation? The “MacBook Wheel”… watch:

Apple Introduces Revolutionary New Laptop With No Keyboard

The goal of an imperfectly competitive firm like Apple is to increase its market power by increasing demand for its particular product through product differentiation, advertising, developing brand loyalty, and “hype”: all forms of non-price competition. If Apple were to simply charge a lower price than its competitors for its products, it would also succeed in increasing the amount of computers it sells to consumers, but may also end up accepting lower profits due to the lower prices it must sell for.

Through differentiation, which means making its products unique and attractive to consumers, Apple attempts to increase market demand for its computers, while simultaneously making demand less elastic. With higher, more inelastic demand, Apple gains price-making power over the laptop computer market, as can be seen in the graphs below, which show that after the successful launch of a new product like the MacBook wheel Apple is able to charge a higher price, produce a similar quantity, and earn greater economic profits.

In the video, one customer says that he’d buy “buy almost anything if it’s shiny and its made by Apple”. Such statements reflect that among loyal customers, demand for Apple’s products is highly inelastic. While the firm is certainly not a monopolist in the market for laptop computers, Apple has surely succeeded to increase its market power and thus its power over prices through product differentiation, brand loyalty, and the “hype” surrounding the launch of new products like the MacBook Wheel.

Discussion questions:

  1. In the graphs above, the slopes of the demand curve increases after successful product differentiation by Apple. Why does this happen?
  2. Assuming the market for laptop computers is monopolistically competitive, what will likely happen to Apples economic profits over time? What must Apple do if it wishes to maintain its profits in the long-run?
  3. What are some real ways companies like Apple and its competitors have attempted to differentiate their products over the years? Would YOU buys a MacBook Wheel if it were real?

Amazing innovation in cargo ship technology – WIND powered vessels!

Kite Powered Ship Sets Sail for Greener Futhre – Guardian.co.uk

A German engineer has given an old technology new life to help make trans-oceanic shipping greener and least costly.

A cargo ship pulled by a giant, parachute-shaped kite will leave Germany on Tuesday on a voyage that could herald a new “green” age of commercial sailing on the high seas.

The owners of the MS Beluga, a 462ft cargo vessel, will try to prove that modern steel ships can harness wind power and reduce their reliance on diesel engines.

During the journey from Bremen to Venezuela, the crew will deploy a SkySail, a 160 square metre kite which will fly more than 600ft above the vessel, where winds are stronger and more consistent than at sea level.

Its inventor, Stephan Wrage, a 34-year-old German engineer, claims the kite will significantly reduce carbon emissions, cutting diesel consumption by up to 20 per cent and saving £800 a day in fuel costs. He believes an even bigger kite, up to 5,000 square metres, could result in fuel savings of up to 35 per cent.

Here’s a thought… reduced fuel costs to trans-oceanic shipping companies should shift the supply of such services out, as the marginal cost of shipping falls. Greater supply will mean lower prices to customers demanding such services, moving downward along the demand curve, increasing the equilibrium quantity of trans-oceanic cargo journeys.

Question: Assume all cargo ships in the world eventually incorporate the sail technology, increasing the supply and reducing the price of shipping by an average of 20% and reducing the emission of greenhouse gases of vessels by an average of 20%. What would have to be true about the price elasticity of demand for trans-oceanic shipping in order for a 20% reduction in price to result in an overall reduction of greenhouse gas emissions by cargo ships? Depending on the answer to this question, this “green” technology could actually result in greater emissions of greenhouse gases by cargo ships.

Explain…

It’s all about DEMAND!

FT.com / World – Air fares nosedive amid falling travel demand

Our IB and AP Econ classes here at Zurich International School have just begun our second unit of the year, where the concepts of Demand and Supply are introduced and the effect these have on prices is examined. The first assignment of the new unit was for each student to find an article discussing the demand for a particular good, service or resource, and post it to our Unit 2 wiki page.

If it’s ever unclear whether a change in demand for a good or a service can actually affect the price, the article linked here should make it perfectly clear that demand is a powerful market force. In an industry where it has seemed recently that prices only rise, a recent fall in market demand has driven prices downward, as firms have responded to consumer demand in order to sell their product, which in this case are seats on short and long-haul flights within and from Europe.

Falling demand for business and leisure travel is causing a marked decline in air fares, with UK fares to North America declining by nearly a half, according to American Express.

Air fares peaked earlier this year as a result of rising oil costs. But the slowing global economy has caused that to reverse.

The lowest economy class fares in Europe, the Middle East and Africa fell on average by 12.5 per cent in April to June compared with the first quarter, with long-haul fares down more than a quarter.

But UK fares suffered the sharpest falls, with the lowest economy fares down by an average of 20.2 per cent, including a 49 per cent fall in fares to North America and a 22 per cent decline in fares to Japan, Asia-Pacific and Australia.

Discussion questions:

  1. What factors are driving demand for air travel down within, to and from Europe?
  2. Why does the price of air travel fall as demand for air travel weakens?
  3. Which other industries may have to lower their prices as fewer and fewer people travel between European countries and North America?

Gas Price Floor Should Be Set At $4 A Gallon

At $4, Everybody Gets Rational – Washingtonpost.com

Here is another excellent gas price article containing accurate economic principles.

Yes, the non-economist (ie, average citizen) doesn’t get it on how higher gas prices will ultimately lead a nation’s economy to conservation, energy independence and efficiency in the long run.

Hey, I’ll be honest: I don’t like higher gas prices any more than I do going to the dentist, but I am glad they are rising as I see and read about SUV purchases falling off a cliff, driving habits changing right before my very eyes, and the quantity demanded for gasoline falling fast.

By CHARLES KRAUTHAMMER | Posted Friday, June 06, 2008

So now we know: The price point is $4.

At $3 a gallon, Americans just grin and bear it, suck it up, and, while complaining profusely, keep driving like crazy.

At $4, it is a world transformed. Americans become rational creatures. Mass transit ridership is at a 50-year high. Driving is down 4%. (Any U.S. decline is something close to a miracle.) Hybrids and compacts are flying off the lots. SUV sales are in free fall.

The wholesale flight from gas guzzlers is stunning in its swiftness, but utterly predictable. Everything has a price point. Remember that “love affair” with SUVs? Love, it seems, has its price too.

America’s sudden change in car-buying habits makes suitable mockery of that absurd debate Congress put on last December on fuel efficiency standards. At stake was precisely what miles-per-gallon average would every car company’s fleet have to meet by precisely what date.

It was one out-of-a-hat number (35 mpg) compounded by another (by 2020). It involved, as always, dozens of regulations, loopholes and throws at a dartboard. And we already knew from past history what the fleet average number does.

When oil is cheap and everybody wants a gas guzzler, fuel efficiency standards force manufacturers to make cars that nobody wants to buy. When gas prices go through the roof, this agent of inefficiency becomes an utter redundancy.

At $4 a gallon, the fleet composition is changing spontaneously and overnight, not over the 13 years mandated by Congress. (Even Stalin had the modesty to restrict himself to five-year plans.)

Just Tuesday, GM announced that it would shutter four SUV and truck plants, add a third shift to its compact and midsize sedan plants in Ohio and Michigan, and green-light for 2010 the Chevy Volt, an electric hybrid.

Some things, like renal physiology, are difficult. Some things, like Arab-Israeli peace, are impossible. And some things are preternaturally simple. You want more fuel-efficient cars? Don’t regulate. Don’t mandate. Don’t scold. Don’t appeal to the better angels of our nature. Do one thing:

Hike the cost of gas until you find the price point.

Unfortunately, instead of hiking the price ourselves by means of a gasoline tax that could be instantly refunded to the American people in the form of lower payroll taxes, we let the Saudis, Venezuelans, Russians and Iranians do the taxing for us — and pocket the money that the tax would have recycled back to the American worker.

This is insanity. For 25 years and with utter futility (starting with “The Oil-Bust Panic,” the New Republic, February 1983), I have been advocating the cure: a U.S. energy tax as a way to curtail consumption and keep the money at home.

In May 2004 (and again in November 2005), I called for “the government — through a tax — to establish a new floor for gasoline,” by fully taxing any drop in price below a certain benchmark.

The point was to suppress demand and to keep the savings (from any subsequent world price drop) at home in the U.S. Treasury rather than going abroad. At the time, oil was $41 a barrel. It is now $123.

But instead of doing the obvious — tax the damn thing — we go through spasms of destructive alternatives, such as efficiency standards, ethanol mandates and now a crazy carbon cap-and-trade system the Senate debated last week. These are infinitely complex mandates for inefficiency and invitations to corruption. But they have a singular virtue: They hide the cost to the American consumer.

Want to wean us off oil? Be open and honest. The British are paying $8 a gallon for petrol. Goldman Sachs is predicting we will be paying $6 by next year. Why have the extra $2 (above the current $4) go abroad? Have it go to the U.S. Treasury as a gasoline tax and be recycled back into lower payroll taxes.

Announce a schedule of gas tax hikes of 50 cents every six months for the next two years. And put a tax floor under $4 gasoline, so that as high gas prices transform the U.S. auto fleet, change driving habits and thus hugely reduce U.S. demand — and bring down world crude oil prices — the American consumer and the American economy reap all of the benefit.

Herewith concludes my annual exercise in futility. By the time I advocate the tax floor again next year, you’ll be paying for gas in bullion.

$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.

Reflections on the weak dollar

I recently received an email from Sean Stoner, who writes a great blog, Maslow Forgot About Beer. I had previously commented on a post Sean wrote about McCain and Clinton’s proposed gas tax holiday, which is how he found my blog. Sean wanted to know my views on the weak dollar:
Jason,

What do you believe is the most direct cause(s) of the weakening of the dollar? Is it the trade deficit and/or spending deficits along with increased borrowing overseas? Is it offshoring? Tax cuts? And how direct is the causality of this to oil and commodity prices?

Of course I’ll give you full credit in the post for educating me more on this subject. Thanks in advance !

Sean

Below is my reply. I am posting it here for posterity, and because I think it may include one possible explanation of the weak dollar within the grasp of IB and AP Econ students:

Hi Sean,

Keep in mind, I’m no expert here, only a high school economics teacher… but let me just share a few thoughts about one cause of the weak dollar.

I think something you’ve forgotten to mention in your email is the role that the mortgage crisis has had on the dollar. Much of the debt from the sub-prime mortgage market was held by overseas investors. As home foreclosures picked up late last year, confidence in these mortgage-backed securities plummeted and demand for these American assets fell, thus demand for dollars among foreign investors has fallen with it, depreciating the dollar.

I think the housing market is at the core of a lot of our woes right now. In my econ class we talk about the “wealth effect” of falling home prices on consumer spending. Besides disposable income, the main determinant of overall consumption in the economy is the level of “wealth” among households. Of course, Americans’ greatest source of wealth is their homes… and the reason home prices have fallen is a simple supply and demand story, which is within the grasps of anyone who knows how supply and demand interact to determine price in a marketplace.

Low interest rates during the late Greenspan era spurred a period of new home sales, which drove prices up, spurring a building frenzy which shifted supply out. As long as demand increased more rapidly than supply, the illusion that house prices would continually rise was believable, thus buyers could be convinced that an adjustable rate mortgage (ARM) was the perfect type of loan for them. But the rising prices were unsustainable, and when the Fed began increasing interest rates a few years ago, demand for new homes declined, right as inventory was at an all time high. Naturally, home prices began to stabilize then fall, and as the “adjustable” part of all those “sub-prime” ARMs kicked in, monthly payments became too much for some Americans to bear. In an attempt to liquidate their now unaffordable houses, millions of Americans put their homes for sale, while thousands began to default on their loans, both which combined to shift supply ever further outward, putting even more downward pressure on home prices.

The story continues from here: falling home prices mean less “wealth” which means less consumer spending which means less total output in the economy which means less demand for workers which means rising unemployment… aka, RECESSION! And that’s where we are today.

So, as you can see I think the housing market is at the core of our problems. The weak dollar too, as demand for American homeowners’ debt has declined among foreign investors. Now, in the face of a recession, the Fed has lowered interest rates once again to try and stimulate new spending and investment, further exacerbating the dollar’s decline, as lower returns in the US bond market divert investors out of dollars and into more secure investments, such as… you guessed it, OIL.

The falling dollar had encouraged investors to look for stable investments, such as commodities like oil, copper, coal, etc, driving demand and prices for these commodities up, contributing to the cost-push inflation that has accompanied America’s economics slowdown.

So yes, it’s all connected… rising unemployment, sluggish growth, rising price levels and falling real wages. At the core, however, is the housing market and the “irrational exuberance” that led to a speculative building and buying spree over the last six years: a bubble which began bursting late last year and continues to have a ripple effect across the economy.

Bush’s tax cuts and deficit spending just made this whole mess even worse. I did a blog post a while back about the trade deficit with China, budget deficits and the value of the dollar, you can read that here: “Excuse me China, could you lend us another billion?”

Okay, that’s all I’ve got for you today… I hope some of these observations are useful!

Best, Jason

“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 goodsprices, 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?
