Letting markets work: the Malaysia fuel subsidy goes bye bye

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?

Is bicycle transportation an “inferior good”?

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.

The concept of cross-price elasticity of demand measures the responsiveness of consumers of one good or service to the change in price of another. 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 concept of cross-price elasticity of demand. 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). The principle of cross-price elasticity of demand says that when the price of a good like personal vehicular transport becomes more expensive (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.

“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.

More on Obama, Clinton, and the “gas tax holiday”

Clinton thinks suspending the gas tax for the summer is good for Americans. She says that any revenue lost can be made up for by taxing the profits of oil companies.

Obama thinks it will cause more harm than good to the economy. He says the $9 billion of government revenue foregone could have done more good for the economy through job creation and road maintenance than the $25 each American driver will save with a suspension of the gas tax.

They’re both using their positions on the gas tax to garner more support among Democratic voters in Indiana and North Carolina, where next week’s key primaries will be held.

Greg Mankiw
, Harvard economist, has this to say about Hillary’s plan:

I don’t know any prominent economist who favors this McCain-Clinton proposal. More common is the reaction of a friend of mine (a veteran of the Clinton administration) who calls the idea “ludicrous.”

Sometimes a candidate’s position on one particular issue, even a relatively minor one like a federal gas tax that most Americans probably didn’t even know they were paying when they filled up their tanks, draws clear lines around a candidate’s values.

Clinton’s ‘Trouble’ ad

Obama Takes On Clinton and McCain on Gas Tax Holiday

It should be noted that while Obama is probably right that a gas tax suspension will only save drivers a pittance, his economics is slightly flawed. Here’s Tim Haab of Environmental Economics blog responding to Obama’s claim that a gas tax holiday could actually increase demand for gas thus raise gas prices:

Wrong, wrong, wrong: A lower gas price causes quantity demanded to increase as consumers move down the demand curve. The only things that cause gas demand to change are changes in income, prices of substitutes and complements, tastes and preferences and expectations… I demand a retraction.

Who are these “some economists” that Obama is talking about? Did they get their degrees from an SEC school or something? Name names so that we can have an econoblogosphere beatdown! Out these blasphemers!

Note: I think Obama got the $25 to $30 number correct.

Mr. Haab is technically correct when it comes to basic economic theory. Repealing the gas tax should shift supply out, not demand, as taxes are a determinant of supply. Rather than demand changing, quantity demanded by drivers will increase, in response to the increased supply and lower prices.

What I do think could happen, however, is that expectations of future price increases might incentivize drivers to increase their demand for gas over the summer. This Mr. Haab seems to oversee. When August roles around and drivers know that come Labor day the gas tax will kick in again, they may chose to take a family road trip that they otherwise would have postponed, shifting overall demand for gas out, driving prices up.

In the case of a temporary suspension of an excise tax on any good, there is always the expectation that the price will increase again in the future. This could lead to hoarding or stockpiling of the good, increasing overall demand and driving the price up before the tax has even returned.

Obama vs. McCain and Clinton on gas tax relief

As Clinton Seeks Gas Tax Break for Summer, Obama Says No - New York Times

Times are tough for American consumers. Rising food and fuel prices have increased the proportion of household incomes that must be allocated towards these two necessities, both for which demand is highly inelastic, meaning that as their prices rise, the quantity demanded by consumers remains relatively high.

In response to the pinching of Americans’ pocketbooks, two presidential candidates are advocating action at the federal level.

Senator Hillary Rodham Clinton lined up with Senator John McCain, the presumptive Republican nominee for president, in endorsing a plan to suspend the federal excise tax on gasoline, 18.4 cents a gallon, for the summer travel season.

Sounds like a good idea, right? If Americans are finding it burdensome to pay more at the pump, and the government can do something to relieve that burden, why shouldn’t they do it?

Let’s do a little calculation here: At 18.4 cents per gallon, how much per fill-up will Americans save?

I drive a ‘94 Toyota pick-up, has a 15 gallon tank and gets notoriously poor mileage. I’ll save $2.76 per tank of gas I buy. I usually fill up my truck about once a week during the summer, meaning I’ll save that much each week. McCain wants to suspend the gas tax from Memorial Day until Labor Day, or for a total of about 12 weeks. If Clinton and McCain get their way, I could very well save as much as $33.12 this year! ASTOUNDING!! What a deal for Americans!

Clearly, repealing the gas tax will have only a minor impact on disposable incomes in America. Obama seems to understand this better than the other candidates:

Senator Barack Obama, Mrs. Clinton’s Democratic rival, spoke out firmly against the proposal, saying it would save consumers little and do nothing to curtail oil consumption and imports…

Mr. Obama derided the McCain-Clinton idea of a federal tax holiday as a “short-term, quick-fix” proposal that would do more harm than good, and said the money, which is earmarked for the federal highway trust fund, is badly needed to maintain the nation’s roads and bridges.

The decision to suspend or not suspend federal gas taxes is essentially a cost-benefit decision. The benefit? Well, apparently around $30 per driver, or about half a tank of gas, compliments of the US government. The cost? Read on…

The highway trust fund that the gas tax finances provides money to states and local governments to pay for road and bridge construction, repair and maintenance. Mr. McCain and Mrs. Clinton propose to suspend the tax from Memorial Day to Labor Day, the peak driving season, which would lower tax receipts by roughly $9 billion and potentially cost 300,000 highway construction jobs, according to state highway officials.

There you have it; $9 billion dollars and hundreds of thousands of jobs that won’t be created in order to put half a tank of gas in each American’s car, which if you think about it, will only lead to Americans driving more this summer. Repealing the gas tax may actually induce Americans who weren’t planning road trips to go ahead and take one, increasing the overall demand for gas and driving the price up to the level it would have been with the tax.

And what about the much needed government revenue the tax creates? Hillary has another plan for recouping that loss:

Mrs. Clinton would replace that money with the new tax on oil company profits, an idea that has been kicking around Congress for several years but has not been enacted into law. Mr. McCain would divert tax revenue from other sources to make the highway trust fund whole.

Clearly, Mrs. Clinton needs a refresher course in basic microeconomics. If she had paid attention in AP Economics (did she even take AP Econ?), Clinton would know that a tax on producers of a highly inelastic good such as oil can be passed almost entirely onto the consumers. In this case, the oil companies, when faced with additional federal taxes on profits, will respond by restricting output, which reduces overall supply in oil market, raising the price of the main input for gasoline. Higher input costs for gasoline refineries will reduce overall supply of gasoline, increasing the price paid by consumers at the pump, negating any price-reduction induced by the suspension of the gas tax.

Ultimately, all taxes are borne by the consumers of an inelastic product: gasoline in this case. Whether the tax is levied on drivers directly, or the oil companies “upstream” in the production process, the outcome is the same: supply is restricted and price is higher.

The suspension of a gas tax that only costs Americans $30 over 3 months appears to impose a much greater cost to society than benefit. At least Obama seems to understand the basic economic reasoning behind this fact.

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

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

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

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

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

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

Enter the government:

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

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

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

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

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

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

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

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

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

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

Where have all the iPhones gone?

China Mobile: 400,000 Unlocked iPhones On Our Network (AAPL) - Silicon Alley Insider

Here’s a shocker… although not so surprising if you’ve ridden a Shanghai subway lately and seen the city’s movers and shakers fiddling with their fancy new iPhones:

China Mobile, the biggest wireless carrier in China, said there were 400,000 unlocked iPhones operating on its network at the end of 2007.If true, that represents more than 10% of the 3.7 million iPhones Apple sold last year. Market research firm In-Stat, which included the stat in an email newsletter today, said that total was four times what they had previously estimated. That helps explain where many of the “missing” iPhones have wound up.

This may seem like great news for Apple; I mean, who wouldn’t want to tap the largest cell phone market in the world? Problem is, Apple does not have a deal with either of China’s big mobile carriers, so Apple doesn’t get a cut out of users’ service plans, which account for a huge part of Apples profits in Europe and the US.

Some analysts estimate that AT&T, Apple’s exclusive U.S. carrier partner, pays Apple $15 per month, per iPhone subscriber — $360 over the length of a 2-year contract — which is pure profit.

So I wonder if the real iPhones in China outnumber the fake ones now!?

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.

The Coase Theorem, clear and simple, kind of…

Environmental Economics: What is the Coase Theorem, really?

John Whitehead at Environmental Economics and I have something in common; we both struggle to clearly explain the Coase Theorem. This is a minor topic in AP and IB Economics courses, part of the Market Failure and Externalities units. Basically, the Coase Theorem presents individuals involved in a property rights dispute a market based mechanism for correcting the existence of an externality, as opposed to turning to the government or the legal system. Whitehead’s article linked here goes into a bit more depth than the typical principles text book, but clarifies some of the misconceptions and shortcomings of the basic theorem introduced in those texts.

In all likelihood, high school econ students will never need to know more than the basic version of the Coase Theorem, so this article is most useful for students (or teachers) who want to extend their understanding beyond the basic level. But while we’re on the topic, I thought I’d share my own method for illustrating Coase. This represents the basic version, but I think it illustrates the concept more clearly than the typical example from a text. I tell them a story, here it is:

When I was a kid we lived in this little yellow house outside of Minneapolis, where summers are brutally hot and humid. Our next door neighbor had a huge old oak tree in his yard with branches that spread out over our yard and provided us with shade for playing outside on hot summer days. One day, after a bad lightening storm, our neighbor became afraid that this huge oak tree might someday get struck by lightening and fall on his house, so he decided to cut it down.

Resource market case study: New York’s manhole covers forged with human sweat and blood…

Published by Jason Welker under
