Taxing emissions to cut greenhouse gases, from livestock

Sunday, May 11th, 2008

Much of this past semester, in my environmental economics class, I have discussed various market-based incentive programs to reduce pollution of both our air and our water, regulatory reforms that were only discussed in economics classes when I was an undergraduate, but have become commonplace since then.  Sulfur dioxide emissions, the primary contributor to acid rain, have been traded in U.S. commodity markets for over 10 years now.  

Another proposal we have discussed is one that was recommended by A.G. Pigou many years ago, a tax on emissions.  Emissions taxes and charges of various types, just as with tradable permits, are used around the world to bring about a more efficient reductions of emissions through these market-based or “incentive compatible” regulatory approaches.  These have mostly focused on controlling the emissions of industrial polluters.  The Kyoto Protocol, an agreement to reduce greenhouse gas emissions, calls for using these incentive compatible or market-based pollution reduction regulatory approaches, as they lead to more efficient reduction in pollution, or, cheaper means of achieving reductions in pollution.  The idea is that if we use a cheaper approach to reducing pollution, we will reduce pollution more, and will be less opposed to pollution reductions. 

Mostly, however, agricultural polluters have been given a free ride on pollution control and have faced far less regulation than other industries.  That is certainly true in the U.S. and around here in South Louisiana.  Our sugar farmers are some of our worst polluters, often burning their fields after harvest, sending tons of particulate matter into the air to attack our lungs and eyes, and to reduce visability.  Not all governments have been as soft on agricultural polluters as we have been in the U.S. 

The government of Estonia is serious about reducing greenhouse gases.  Recently, according to this article in Novosti, the government has started taxing cattle because, they, well, fart.  And do it alot.  According to the article, a single cow produces about 350 liters of methane and 1,500 liters of carbon dioxide, both serious contributors to global warming, each and every day.  New Zealand started taxing the flatulence of cows  after they signed the Kyoto agreement, noting that cattle are responsible for 90% of its methane (a very serious greenhouse gas cause) emissions and 43% of its total greenhouse gas emissions. 

Of course, one reason cattle might be taxed in New Zealand has much to do with the eternal battle between cattlemen and sheep ranchers, and New Zealand’s long history with a substantial sheep lobby. 

As a method to reduce greenhouse gases and global warming, Estonia’s and New Zealand’s cattle emissions tax is a good idea. 

Next, though, wives and girlfriends are going to begin to call for a similar tax.

High gas prices, complements and substitutes

Wednesday, May 7th, 2008

This is the last blog post of the semester for any of my students to comment on for extra credit. And they had better be fast about it. Only hours to go. Well, here it is.

Gas prices. Remember those prices you have to be grumbling about when you fill up at the pump? Notice, that there are no lines at the gas stations. Hmm??? Maybe that stuff about price controls causing shortages might be right.

Well, while I was proctoring my Wednesday night class’s final, I read through some articles on Drudgreport.com and came across two articles for this final post that has to do with my 211 principles class. First, this article from the Boston Globe is on how people are trying to get rid of their gas guzzlers because of high gas prices. How about that? The price of gasoline goes up and people start selling off their gas guzzlers and few seem to want to buy them and so their prices are going way down. What was that we said about the effects of the price of complements on the demand for something. Gasoline and gas guzzling cars are complements and so high prices for a complement (gasoline) brings down the demand, and so, the price, of its complement, the gas guzzler.

Another reaction to the high price of gasoline is to switch to substitutes. One substitute for gasoline is time. See this article from New York’s WCBS TV about people slowing down their driving. Driving 100 miles in an hour consumes more gasoline than driving that same 100 miles in 2 hours. Taking more time to get where you are going, slowing down, requires less fuel and so time is substituted for gasoline when gasoline prices climb sky high. A higher price for gasoline and people getting the same wage, the slow down some as people substitute time for gasoline.

Another substitute for gasoline is mass transit.  According to this article in the New York Times, ridership on mass transit systems across the country is growing at very high rates.

Gasoline holiday to fall between Memorial and Labor Day, in reality between April Fools and Trick or Treat

Sunday, May 4th, 2008

In case you haven’t heard, Sen. Clinton and Sen. McCain have each advocated cutting the federal highway-use tax on gasoline from Memorial Day to Labor Day to save drivers (rather, voters) a whole 18.4 cents per gallon, which amounts to about 5% of what they spend on gasoline. Senator McCain suggests making up the difference in the federal highway infrastructure fund with money from the federal government’s general fund, adding about $10 billion to our already blossoming federal deficit. Sen. Clinton, along with Sen. Obama have advocated placing a windfall profits tax on the oil companies . Obama, it should be noted, has opposed the Clinton-McCain gas tax holiday.

 

Some opponents of the tax holiday (New York Times Blog and Wall Street Journal) have countered that the short-term tax break would not affect prices that consumers pay, and these opponents are correct. Think about the underlying downward-sloping demand and somewhat upward-sloping supply of gasoline. The short-term upward-sloping supply of gasoline, during the summer months, becomes vertical, as the refineries in the U.S. are all operating at their maximum output levels. With a completely inelastic supply of gasoline, all of any tax falls on the suppliers, but all of any tax-cut is enjoyed by the suppliers. If the price to buyers were to decrease at all from their present levels, the quantity demanded would increase as buyers respond to lower prices by buying more, which we know from the law of demand. But with no more units able to be supplied by refiners, there would be a shortage which would push the price up, back up to its original level. This would save nothing for tax payers over the summer and would cut highway infrastructure moneys, money that could build new bridges, like the ones we see we could use after the Minneapolis bridge disaster last year.

 

A similar disaster for the millions of drivers would occur with Clinton and Obama’s windfall profits tax on oil. The Carter windfall-profits tax amounted to little more than an excise tax on gasoline from domestic oil, raising gas prices for consumers, cutting the profits on domestic oil, cutting domestic production, and raising reliance on foreign oil. Even if a tax were devised that taxed just profits, which is not what happened with the 1980 windfall profits tax under Jimmy Carter, the long-run results of such a tax would be to make refineries less profitable, reducing long-run supply from what it would have been otherwise, and raising the price of gasoline at the pumps from what it would have been. The Obama plan would put a tax on every barrel of oil that sold at a price higher than $80, which would mostly just get passed along to consumers, who have a very inelastic demand for oil, while oil companies could easily sell their oil outside of the US without the tax (elastic supply of oil to the US), reducing the amount of oil supplied in the US and increasing the prices at the pumps for consumers.

 

But this increase in prices because of the tax is something that consumers never see, never seem to notice, and blame the higher prices on the oil companies, and not on the federal government, just as the high prices from the lack of investment in new refineries is blamed on the oil companies instead of the myriad of federal and state regulations, such as the needed, but ill-designed air pollution regulations.

 

What Clinton and McCain want is a reduction in gas prices now, but their tax-holiday idea, while popular, would completely fail to do what taxpayer/voters want it to do, cut prices at the pump. What it will do is make them relatively more popular than Obama, from what they would have been otherwise (economists say, “ceteris paribus”), because voters hear the speech and believe what their candidate tells them. All Clinton and Obama’s windfall profits tax would do is to raise prices on gasoline, as a tax would tend to fall on consumers who have a relatively inelastic demand for gasoline, instead of on owners of oil companies, the stockholders of oil companies. Stockholders have many options in the long run and will divert their funds away from oil companies if these companies are forced to pay a profits tax. Cutting supply raises price. Cutting supply to a good that has an inelastic price raises price a lot.

 

Clinton says she is “reluctant to throw her lot in with economists.” I’m even reluctant to throw my lot in with politicians. While corporations that lie in their ads and promotions can be convicted for fraud, it seems that fraud does not apply to politicians vying for our votes.

 

Two lessons. One, people trying to get elected are to be believed about as much as those emails from the dying wife of the Nigerian Oil Minister who wants to make you rich. The other lesson is that what we have been talking about in class with burdens of taxes and elasticities was to help understand real proposals, and to help us detect BS before we down in it face first.

And here is a little update–other economists weigh in here.
