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?

Chocolate Sales: A Sweet Spot in the Recession – TIME

Living in Switzerland, I find an article featuring a local business from the town my school is in irresistible, particularly when it appear in TIME magazine. Lindt chocolate, the company featured in this article, manufactures its delicate treats right down the hill from the ZIS campus, which means that when the wind is just right, you can just catch the scent of fresh, creamy chocolate wafting up the hillside while walking to campus.

Lindt, as well as its global competitors in the chocolate business, is enjoying surge in demand even while countless other industries are forced to cut back production, lay off workers, and close their factory doors. From TIME:

While the credit crisis has slowed down sales of everything from cars to organic groceries, people seem happy to keep shelling out for chocolate. Last year, as the global recession was gaining ground, Swiss chocolate makers bucked the trend with record sales — nearly 185,000 tons, an increase of 2% over 2007, sold domestically and in 140 export markets…

“Switzerland’s image sells well abroad, and nothing says ‘Switzerland’ more than chocolate,” says Stephane Garelli, director of the World Competitiveness Center at the Institute of Management Development (IMD) in Lausanne, predicting that this comfort food will continue to sweeten the sour economy for months to come…

“Now that people don’t have a new television or a new car,” he noted, “they eat a bit more chocolate.”

“Chocolate is one of the more recession-resilient food sectors,” says Dean Best, executive director of Just-Food, a U.K.-based news and information website for the global food industry. “With consumers eating out less and eating at home more, there is evidence that they are still allowing themselves the occasional indulgence — and chocolate is a relatively inexpensive indulgence.”

But the question of why there is no meltdown in the chocolate business may be more a matter of psychology than economics. “There is well-documented evidence going back to Freud, showing that in times of anxiety and uncertainty, when people need a boost, they turn to chocolate,” says Garelli of the IMD. “That’s why when the economy is bad, chocolate is still selling well.”

Which goes to show that chocolate is more than a candy treat — it’s real food for the soul.

So does this mean chocolate is an inferior good, or one for which demand increases as incomes fall? I doubt many Swiss chocolate producers would consider their product inferior, but perhaps it does fit the definition.

On the other hand, perhaps the reason demand for chocolate increases during a recession has more to do with the substitution effect than the income effect. As people eat out less, they consume fewer expensive deserts at restaurants and instead fill their shopping baskets with more affordable dessert options for the home. I can say from experience that this is the case for myself.

Living in Switzerland, I find myself rarely going out to eat at restaurants, an activity reserved for special occasions in this country where a steak can set you back 75 dollars. Instead, I eat at home almost every night, and nothing is more appealing to me, especially during hard economic times, than a bar of delicious chocolate after a home cooked meal. Demand for chocolate may rise during recessions simply because the demand for one of its substitutes (restaurant desserts) falls.

Discussion questions:

1. Do you think chocolate is an inferior good or a normal good? What’s the difference? What types of goods do YOU consome more of when you find yourself faced with a tighter budget?
2. Does economics have a good explanation for the above situation? The article mentions Freud, a pioneer in  the field of psychology; do humans’ economic behavior always appear rational?
3. If chocolate were an inferior good, what would happen to chocolate sales when the global economy finally turns around and incomes start increasing? What do you think will happen to chocolate sales when the economy starts imrpoving? Explain.

A few summers ago, my wife and I spent three weeks travelling around the island of Bali in Indonesia. For six of those days we rented a jeep and circumnavigated the island. Our first stop was for two days of scuba diving in the northeast region of Ahmed. As we drove along the seven beaches near Ahmed, we observed there were around ten dive operators offering packages for the local dive spots (including one of Asia’s most famous dives, the WWII-era USS Liberty wreck). Based on our Lonely Planet recommendation, we settled on Eco-Dive, where we paid $60 a day for two dives and all our gear rental. We felt good about this rate and agreed that $60 was a fair and competitive price for a day of diving.

Our next stop, Pemuteran, a remote and relatively undeveloped area on the northwest coast just across the straits from Java, is also known for its great diving. On our first morning in Pemuteran, my wife and I strolled along the beach and found that there were only three dive operators to choose from! And guess what, they all charged between $95-$105 for a day of diving. That’s around 60% more than the operators in Ahmed charged! In the end, we decided to do only one day of diving in Pemuteran, and elected to spend our second day there reading by the pool.

Discussion Questions:

1. What was the difference between the scuba diving markets in Ahmed and Pemuteran? Which market was more competitive? Which of the four market structures did the two markets most resemble: perfectly competitive, monopolistically competitive, oligopolistic or monopolistic?
2. How were the dive operators in Pemuteran able to charge 60% more than the operators in Ahmed?
3. What do you think is keeping one of the three dive operators in Pemuteran from lowering their price to, say, $60 for a day of diving? How would the other two operators respond? Would this be good or bad for the dive operators of Pemuteran? Would it be good or bad for scuba divers?
4. Assuming that the cost of opening a dive operation was relatively low, and there were no government or other barriers to doing so in Pemuteran, what do you suspect will happen in the Scuba diving market as the tourism industry continues to develop in the remote town of Pemuteran? Explain.
5. Which village’s dive operators do you think were more “efficient” in their use of resources? Explain.

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.

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…

Op-Ed Contributor – Buy American. I Am. – NYTimes.com

So Wall Street has recently experienced its worst shocks since the great depression. Every day the Dow Jones is like a roller coaster, DOWN 800 points, then  UP 500 points, then DOWN 200 followed by another rally of 600! In just three weeks the Dow has gone from 11,500 to below 900 points. Surely, the wise thing to do is get OUT of the stock market, right? WRONG! At least, so says the richest man in the world, Warren Buffet, someone who should know a thing or two about smart investing.

Why?

A simple rule dictates my buying: Be fearful when others are greedy, and be greedy when others are fearful. And most certainly, fear is now widespread, gripping even seasoned investors. To be sure, investors are right to be wary of highly leveraged entities or businesses in weak competitive positions. But fears regarding the long-term prosperity of the nation’s many sound companies make no sense. These businesses will indeed suffer earnings hiccups, as they always have. But most major companies will be setting new profit records 5, 10 and 20 years from now.

Let me be clear on one point: I can’t predict the short-term movements of the stock market. I haven’t the faintest idea as to whether stocks will be higher or lower a month — or a year — from now. What is likely, however, is that the market will move higher, perhaps substantially so, well before either sentiment or the economy turns up. So if you wait for the robins, spring will be over.

A little history here: During the Depression, the Dow hit its low, 41, on July 8, 1932. Economic conditions, though, kept deteriorating until Franklin D. Roosevelt took office in March 1933. By that time, the market had already advanced 30 percent. Or think back to the early days of World War II, when things were going badly for the United States in Europe and the Pacific. The market hit bottom in April 1942, well before Allied fortunes turned. Again, in the early 1980s, the time to buy stocks was when inflation raged and the economy was in the tank. In short, bad news is an investor’s best friend. It lets you buy a slice of America’s future at a marked-down price.

Over the long term, the stock market news will be good. In the 20th century, the United States endured two world wars and other traumatic and expensive military conflicts; the Depression; a dozen or so recessions and financial panics; oil shocks; a flu epidemic; and the resignation of a disgraced president. Yet the Dow rose from 66 to 11,497.

You might think it would have been impossible for an investor to lose money during a century marked by such an extraordinary gain. But some investors did. The hapless ones bought stocks only when they felt comfort in doing so and then proceeded to sell when the headlines made them queasy.

Today people who hold cash equivalents feel comfortable. They shouldn’t. They have opted for a terrible long-term asset, one that pays virtually nothing and is certain to depreciate in value. Indeed, the policies that government will follow in its efforts to alleviate the current crisis will probably prove inflationary and therefore accelerate declines in the real value of cash accounts.

Equities will almost certainly outperform cash over the next decade, probably by a substantial degree. Those investors who cling now to cash are betting they can efficiently time their move away from it later. In waiting for the comfort of good news, they are ignoring Wayne Gretzky’s advice: “I skate to where the puck is going to be, not to where it has been.”

I don’t like to opine on the stock market, and again I emphasize that I have no idea what the market will do in the short term. Nevertheless, I’ll follow the lead of a restaurant that opened in an empty bank building and then advertised: “Put your mouth where your money was.” Today my money and my mouth both say equities.

Discussion Questions:

1. Why does holding cash seem like the smart thing to do during periods of volatile stock prices like the last month or so? Why does Mr. Buffet think that holding cash is NOT so smart?
2. Mr. Buffet’s advice is counter-intuitive to some. Buying more of something that is falling in value (American stocks) may appear unwise… but what is Buffet’s rationale for why buying now may in fact be the smartest thing for an investor to do?
3. Does the behavior of investors on the stock market reflect the behavior of consumers in a typical product market? In other words, do the laws of supply and demand apply to the stock market? Discuss…

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?

UN chief warns world must urgently increase food production – Yahoo! News

So you don’t say things that make you sound stupid to people who have studied economics, i.e. AP Econ students. Here’s UN chief Ban Ki Moon speaking at a UN conference in Ghana this week:

“One thing is certain, the world has consumed more (food) than it has produced” over the last three years, he said.

Ban blamed a host of causes for the soaring cost of food, including rising oil prices, the fall of the U.S. dollar and natural disasters.

He said he would put together a special task force to help deal with the problem and called on the international community to help…

“We need a real world and not the world of economic theories,” Ban said. “I will work on this right now with a sense of urgency.”

You know who says things like that? People who don’t understand the basic economic theories. Sadly, the theory Mr. Moon is missing here is one of our science’s most basic and simple to understand: that of supply and demand.

First of all, I’d just like to point out the absurdity of his first statement, that “the world has consumed more than it has produced.” Mr. Moon, I’d like to ask you this: If our world has not produced all the food we’ve consumed, then whose world DID produce it? Can’t we just call up the world where all the extra food we’ve consumed was grown and ask them to send us more?

Next, regarding Mr. Moon’s “task force” that he plans to form to deal with the problem, my question is this: What can a handful of bureaucrats accomplish around a table in New York that the market can’t do on its own? Rising food prices send signals to farmers who grow food; a signal that sends a very clear message: “GROW MORE FOOD!”

I’m sorry, but Mr. Moon and his “task force” can spend all the time and money they want brainstorming ways to get farmers to grow more food, but in the mean time the invisible hand of the market, guided by price signals sent from consumers to producers, will work its magic to allocate more resources towards food production and away from alternative uses of grain crops such as ethanol production, eventually shifting the supply curve of food out, stabilizing food prices.

Mr. Moon’s intentions are honorable, but his means of achieving his goal are misguided in an era of the market mechanism, which underpins most of the world’s agricultural economies today.

In recent years coffee consumers may have noticed more and more cafes are offering “fair trade” coffee as an option. Usually, for an extra 10 or 20 cents per cup, you can get a beverage made from beans that were grown by farmers earning living wages and working in safe and sustainable environments. In some cases, “fair trade” coffee is of higher standards, representing a higher quality product. The premium paid by consumers, in theory, will eventually result in better standards of living for coffee farmers and their families.

Mike Munger, chair of Duke University’s economics department, argues that “fair trade” products, while they may represent good intentions, probably don’t do much to help poor farmers. While the full podcast offers even more reasons, the clip below presents one clear explanation of why “fair trade” may actually make poor farmers worse off.

Another interesting point Munger goes on to make relates to one of the models of economic growth we have been studying in IB Economics: the Lewis dual-sector model of structural change. According to the model, the path towards economic growth, which should create conditions that lead to economic development, requires the transition of workers from the low-productivity agricultural sector to the capital-intensive, high productivity manufacturing sector.

China, in its own economic growth, has demonstrated the success of this model, which involved rural to urban migration, employment of surplus labor from the farming sector in the industrial sector, giving workers access to capital, increasing productivity, output, income, saving, and investment, putting an economy on a path towards growth and development.

According to Munger, “fair trade” premiums paid to poor farmers create a disincentive for a farmer to migrate to the higher productivity industrial sector that may be emerging in his country. In essence, coffee drinkers in the rich world are offering a subsidy to farmers in the poor world aimed at keeping them poor. If the path to wealth and prosperity requires the transition to a capital-intensive industrial economy, then subsidies to poor farmers are only reducing the likelihood that they’ll achieve significant increases in income and savings.

Munger’s views are compelling, if a bit hard for a socially conscious, well-intentioned coffee lover like myself to swallow. I like to think that I’m helping farmers in the developing world when I drink “fair trade” coffee. If anything, Munger has at least made me think a bit harder about the true impact of the premium I pay when I choose “fair trade” next time I walk into Starbucks.

Well, not exactly, but that’s kind of a dramatic headline, isn’t it? The other day I blogged about the shortages experienced in the petrol market in eastern provinces, evidenced by the long queues at gas stations around Shanghai last weekend.

Petrol stations resorted to rationing their product in small doses (between 20 and 40 litres) as the price of oil hit $92 and Chinese refiners scaled back production due to rising costs that they were unable to pass on to their customers. Beijing had previously imposed a price ceiling on fuel in an attempt to keep inflation low and Chinese consumers content; the actual impact of this price control was predictable: not enough fuel to go around as the quantity demanded exceeded the quantity supplied, leading to shortages and rationing at the pump.

Well, it looks like Beijing is finally catching on to the flawed nature of their iron fisted attempts at overpowering the forces of the free market, sort of:

FT.com / Asia-Pacific / China – China pushes up fuel prices

“China raised the price of petrol and diesel by almost 10 per cent on Wednesday as crude oil prices hit a record above $94 a barrel.

The move, the first increase since May 2006, came in spite of a promise by Beijing not to put up state-controlled prices before the end of the year in an effort to keep inflation at bay.

Inflation in China exceeded 6 per cent in the third quarter amid rising food-price increases that some fear could lead to social unrest…

The retail price rise in China could stimulate demand in the short term as refiners resume production, and is unlikely to dampen long-term demand, analysts said.”

That last sentence seems strange to me. In what scenario that we have studied would a price increase ever “stimulate demand”? I suspect what the article means is that the price increase will “stimulate supply” as refiners (the producers of fuel), are now able to sell their output at a higher price (or marginal revenue), meaning that the profit maximizing level of output is greater, or higher along their marginal cost curves.

So, output should increase in the fuel industry, which means there will be more fuel for consumers to buy. But surely consumer demand will not increase; this seems to defy the law of demand! What does seem likely, however, is that the higher price (essentially a less restrictive price ceiling), will increase the quantity supplied, thus increasing the amount of fuel available for consumers to buy, alleviating the shortage and allowing Chinese to consume a greater quantity than when the price ceiling was more restrictive.

In fact, the quantity demanded will go down (as the higher price leads to leftward movement along the demand curve), but the quantity consumed will go up (as the higher price leads to a rightward movement along the supply curve). A shortage is being alleviated, but probably not eliminated, considering the price of the raw material in fuel (oil) has increased 40% in the last year, while the price of fuel has only increased 10% since May of 2006. It seems likely that the government set price is still an effective ceiling, meaning there is still excess demand, and therefore we may be seeing more lines of blue trucks around Shanghai in the future!

Mali’s Farmers Discover a Weed’s Potential Power – Sept 6, New York Times

Can it be possible that a new use for an old weed could change the economic health of a nation and at the same time defy the law of opportunity costs? In Mali, farmers are choosing to plant more of weed called jatropha becuase it can now be turned into biofuel. It is a unique plant in that it needs marginal soil and requires little fertilizer. In class we have talked about how discovering a new resource can cause economic growth, how this can shift the PPC curve. But, can a country actually get the benefits of using this new resource with out any opportunity cost? Is what is happening in Mali an example of economic development or economic growth in the first place? Is this a supply or a demand issue?

But now that a plant called jatropha is being hailed by scientists and policy makers as a potentially ideal source of biofuel, a plant that can grow in marginal soil or beside food crops, that does not require a lot of fertilizer and yields many times as much biofuel per acre planted as corn and many other potential biofuels. By planting a row of jatropha for every seven rows of regular crops, Mr. Banani could double his income on the field in the first year and lose none of his usual yield from his field.

You be the judge of why Mali is making the decision to produce more jatropha. Is this a case for demand or supply? Which curve would shift? Which determinant is causing this shift?

But here in Mali, one of the poorest nations on earth, a number of small-scale projects aimed at solving local problems — the lack of electricity and rural poverty — are blossoming across the country to use the existing supply of jatropha to fuel specially modified generators in villages far off the electrical grid.

“We are focused on solving our own energy problems and reducing poverty,” said Aboubacar Samaké, director of a government project aimed at promoting renewable energy. “If it helps the world, that is good, too.”

This is very interesting information for you to consider as you are wondering about environmental sustainability, a real life economic issue.

Jatropha’s proponents say it avoids the major pitfalls of other biofuels, which pose significant environmental and social risks. Places that struggle to feed their populations, like Mali and the rest of the arid Sahel region, can scarcely afford to give up cultivable land for growing biofuel crops. Other potential biofuels, like palm oil, have encountered resistance by environmentalists because plantations have encroached on rain forests and other natural habitats.

But jatropha can grow on virtually barren land with relatively little rainfall, so it can be planted in places where food does not grow well. It can also be planted beside other crops farmers grow here, like millet, peanuts and beans, without substantially reducing the yield of the fields; it may even help improve output of food crops by, among other things, preventing erosion and keeping animals out.

So try to apply what you have learned about opportunity costs, economic growth and development, as well as supply and demand and analyze these economic events in Mali. I look forward to your comments

Demand Down, but Rents Up – washingtonpost.com

Alright, AP students… you are economics detectives and you’ve been assigned your first case. The mystery is thus: how can decreasing demand cause prices to go up? In chapter three, we are reading about product markets, the interaction of supply and demand, and market equilibrium price and quantity. You’ve read that prices are affected by the interaction of supply and demand. Clearly, if demand for a product rises, prices should go up unless supply increases a certain amount. On the other hand, if demand falls, then prices should fall unless supply falls at the same time.

So what’s happening in the article above? The headlines seems to proclaim an economic impossibility is occurring: as demand falls, prices rise! How is this possible? Is it? Is the market for apartments in the D.C. area defying the laws of demand and supply? Read the article and see if you can solve this economic mystery!

Starbucks Raising US Drink Prices Next Week – Reuters.com

One of the first things that my jet lagged family noticed when we got back from San Francisco was that Starbucks had opened up around the corner from our house in Zhudi Town. Normally, my family travels far and wide to buy coffee beans at the Starbucks in Gubei or at the Portman because my husband Kevin, a sophisticated caffeine addict, needs his well roasted coffee. Now my husband can just walk down the street to find his fix. Let’s just say that he now is very happy. My kids, Maya and Cooper, are extremely happy too because when they walked into the Starbucks Café, some smiling ladies behind the counter gave each of them a free gift. The gift was small packet of yellow sculpting clay. So much for teaching them that there is “no such thing as a free lunch” early in life.

I, on the other hand, had a lot of unanswered economic questions running through my mind when we into the café, For example, why did Starbucks open up here in Zhudi? What would this mean for my favorite local joint, The Rendevous Café? Is competition always a good thing? And what about my core value of “think globally and buy locally”? All of these questions continued swirling around in my mind as I had breakfast (with nicely brewed tea) at the newly updated Rendevous Café. As we were eating, the local owners came by our table and personally welcomed us back from vacation. I commented on how nice the place looked and the owners told me that the updates to the restaurant were a response to the new competition from Starbucks and Johnny Moos. The owners looked a little worried. For a long time they have been the only place in town where locals and SAS faculty and students could stop by for a western breakfast, lunch, dinner or coffee. Now, there is real competition. Rendevous’ food is definitely good but can they survive with this competition?

I ran home (well, a little overstated) and got online to see if I could catch up on the latest information about Starbucks Inc. and their plans for China. I was amazed to learn that Starbucks had just announced,

“Starbucks Corp will raise U.S. prices on coffee, lattes and other drinks by an average of 9 cents a cup next week to help offset soaring costs for milk and other commodities, a spokesman said on Monday, July 23, 2007.The widely anticipated move marks Starbucks’ second price increase in less than a year and comes a month after the coffee shop chain’s chief financial officer warned it would be “very challenging” for Starbucks to meet the high end of its 2007 earnings forecast, in part because of rising dairy prices.”

Also it was noted on a Chinese business website that in China, Starbucks will increase the price of their coffee drinks by as much as 5RMB in Beijing and 3RMB in Guangzhou. Dessert prices will remain the same. That got me wondering again, what is going to happen if the price of coffee drinks go up just as this new Starbucks is taking off in Zhudi Town? Will people stop going to Starbucks because of the increase in the cost of coffee drinks?

So, Starbucks has arrived in Zhudi. I know that many people are really happy but I am not sure if it is time to say hooray just yet. We will have to let the free market forces go forth and let the chips fall where they may. I certainly hope that Rendezvous Café is still standing when all the chips have fallen.

Discussion Questions:

1. What economic forces brought Starbucks to Zhudi? Name them and graph them.
2. What kind of market structure do fast food/coffee restaurants have? Explain. How do they compete with each other.
3. Will an increase in price of Starbucks coffee drinks affect people’s decision to buy coffee from Starbucks? Why? Why not?
   
4. Is there really such a thing as a, “free lunch? Explain.
   
5. Can Rendezvous café survive given its competition?

While students and teachers across America settle into their summer routine and look forward to three more weeks of summer vacation, the first week of August marks an unseen exodus of thousands of international students and teachers in countries on every continent. For some reason, international schools all seem to start about two weeks earlier than the post-Labor day start date enjoyed by most public school in the US. Here at Shanghai American school, teachers arrive in droves around the 7th and 8th of August, just in time for our first work day on the 9th.

My wife and I returned to 95 degree heat from the pleasant 70′s of Seattle last night to begin preparing for our second year at Shanghai American School. In a week SAS will welcome around 2900 students, making it one of the largest international schools in the world. As part of our orientation this morning, our director, Dr. Dennis Larkin, shared a bit of SAS’s 95 year history with the faculty, enlightening many of us to the school’s storied past stretching back to the concession era of Shanghai’s “golden age” when thousands of Westerners made their settlements in the city’s center. 100 years ago Shanghai underwent a renaissance unseen in China’s thousands of years of history. European influence brought the city into the 20th century architecturally, culturally, economically, and perhaps more notoriously in the realm of criminal activity as gangsters took over the city through much of the 20′s and 30′s.

With the large Western presence came a demand for Western schools, thus in 1912 Shanghai American School welcomed its first class of 12 students. By the 20′s enrollment rose to 600, and by the 30′s it approached 1,000. In 1937 China was invaded by Japan, and foreign firms and embassies began nervously moving their people out of Shanghai. By 1939 Shanghai had fallen to the Japanese and the school grounds were occupied by Japanese troops. But with the surrender of the Japanese in 1945, the school was back in operation, albeit for only a short time as a civil war between the Chinese Communist Party and the US backed Nationalists brought violence to the streets of Shanghai once more. By 1950 Beijing had fallen to Mao and the Communists, and SAS was shut down “for good”. Its doors would remained closed for 30 years until 1980, when Mao had died and Deng Xiaoping had ushered in the era of “Reform and Opening”, a euphemism for westernization. Once again SAS opened for business.

In the 27 years since the school’s rebirth, the student body has grown from the seven children of American diplomats to 2,900 students from over 50 countries. In the last five years alone the student body has nearly doubled in size, as the school has added a second campus and countless new buildings to serve the growing population of foreigners in Shanghai. Over the same 27 years, around ten other international schools have opened in Shanghai, some with two or three campuses spread across the vast city, several serving over 1000 students also from scores of foreign countries. What impact has the opening and expansion of SAS and other international schools had on tuition paid by foreign students in Shanghai? You may think that with so many schools competing to attract students, each school would have to lower its fees in order to attract students away from its competitors. Well, you’d be wrong. SAS increased its tuition fees by 10% this year, bringing a year’s tuition to around $22,000. Its competitors charge something in the same ballpark, meaning a year of schooling at any of Shanghai’s international schools will cost a family more than a year’s tuition at most state universities in the US.

Discussion Questions:

So, what does all this history and data have to do with economics? Here’s a simple supply and demand question for you. In 1980, international schools in Shanghai had room for, let’s say 20 students total. I am not sure, but I’d guess tuition in 1980 probably ran around $2,000. Today, there are somewhere around 10 international schools with room for probably around 10,000 students, and the average tuition is somewhere in the realm of $20,000.

1. How would an economist explain the 1,000% increase in tuition over the last 27 years, given the fact that today international schools in Shanghai have the capacity to serve 500 times as many students as they could in 1980?
2. Could you draw a supply and demand diagram illustrating the changes that have occurred since 1980 in the market for international education in Shanghai?
3. Let’s be honest, $22,000 is a lot of money for a year of school. What would have to happen in the market for international education in Shanghai for the tuition fees to go down? Identify two scenarios that would result in a tuition decrease. Illustrate these scenarios on your diagram.

Freakonomics: Monkey Business: Keith Chen’s Monkey Research

No I’m not talking about the latest freshman class at an Ivy League school… rather a group of monkeys at Yale that have been taught how to use money:

The essential idea was to give a monkey a dollar and see what it did with it. The currency Chen settled on was a silver disc, one inch in diameter, with a hole in the middle — ”kind of like Chinese money,” he says. It took several months of rudimentary repetition to teach the monkeys that these tokens were valuable as a means of exchange for a treat and would be similarly valuable the next day. Having gained that understanding, a capuchin would then be presented with 12 tokens on a tray and have to decide how many to surrender for, say, Jell-O cubes versus grapes. This first step allowed each capuchin to reveal its preferences and to grasp the concept of budgeting.

Turns out the law of Demand is not only true for humans but for monkeys too. When Chen “lowered the price of grapes”, monkeys would buy more grapes and less Jell-O, following the basic rule of utility maximization. Interestingly, the introduction of money led to more than just the simple exchanges of currency for candy and cucumber; the monkeys were also taught to gamble. Through their observations of several gambling scenarios, the researchers found monkeys tended to display “loss averse” behavior in games of chance, leading to an amusing conclusion:

The data generated by the capuchin monkeys, Chen says, ”make them statistically indistinguishable from most stock-market investors.”

Sadly, gambling was not the only vice that accompanied the introduction of money in to monkey society:

Then there is the stealing. Santos has observed that the monkeys never deliberately save any money, but they do sometimes purloin a token or two during an experiment.

But the debauchery does not stop with gambling and theft:

Perhaps the most distinguishing characteristic of money, after all, is its fungibility, the fact that it can be used to buy not just food but anything. During the chaos in the monkey cage, Chen saw something out of the corner of his eye that he would later try to play down but in his heart of hearts he knew to be true. What he witnessed was probably the first observed exchange of money for sex in the history of monkeykind. (Further proof that the monkeys truly understood money: the monkey who was paid for sex immediately traded the token in for a grape.)

As if we needed any proof beyond the widespread immorality and loss of values that distinguish many rich human societies, the steep decline of monkey morality observed at Yale can only be attributed to the introduction of currency! The implications of the Yale study on economics are clear: humans are not necessarily unique in our understanding of currency as a means of exchange. As long as money has imbued human societies, the wont to enrich ourselves through immoral means such as gambling, theft and prostitution has stained civilizations from ancient Mesopotamia to modern America.

When taught to use money, a group of capuchin monkeys responded quite rationally to simple incentives; responded irrationally to risky gambles; failed to save; stole when they could; used money for food and, on occasion, sex. In other words, they behaved a good bit like the creature that most of Chen’s more traditional colleagues study: Homo sapiens.

To make a more poignant observation, one thing is clear and disturbing, among the human societies today, Americans are most like monkeys when it comes to saving.

Discussion Questions:

1. Of the various functions of money, which role does money play for monkeys?
2. What gives the money used by the monkeys its value?
3. Discuss the evidence from this article suggesting that monkeys follow the law of demand.
4. What is the utility maximization rule and what evidence from this article supports the suggestion that monkeys follow this rule?
5. How are monkeys more similar to American consumers than to, say, Japanese or Chinese consumers?
