Energy Errors

Charles Mann has an interesting article on unconventional oil and gas in the Atlantic. Lots of good stories and  he cites Morris Adelman so it is a worthwhile article. But two glaring errors induce this post.

First, is this concept of EROEI. Let's quote Mann:

Economists sometimes describe a fuel in terms of its energy return on energy invested (EROEI), a measure of how much energy must be used up to acquire, process, and deliver the fuel in a useful form. OPEC oil, for example, is typically estimated to have an EROEI of 12 to 18, which means that 12 to 18 barrels of oil are produced at the wellhead for every barrel of oil consumed during their production. In this calculation, tar sands look awful: they have an EROEI of 4 to 7.

I am fully aware that some analysts use this concept, but I cannot believe that any economist would. The whole point of economics is to compare the value of inputs and the value of outputs. Not their physical unit measures. If you use lots of low-cost energy to create high value energy that is a good thing even if the quantity of the low-cost energy is huge. In this example, Mann talks about barrels of oil for barrels of oil. Sometimes the measure is in BTU's or some other physical unit, but the same error arises. We use coal to produce electricity because electricity is a more valuable type of energy -- try powering your ipad directly with coal.  Later in the article Mann talks about Econ 101, but if he took it he would not make this error.

Second, Mann goes on and on about the resource curse. The idea that resource abundance causes deteriorating economic performance has been much studied. But as Mike Alexeev and Robert Conrad clearly demonstrated it is an elusive curse. Alexeev and Conrad's paper should have ended these discussions, but they endure. This despite the fact that the empirical work that purports to find a resource curse is flawed for many reasons. But the most important is the failure to consider what the wealth of the country would be without the resources. That is correct, this is actually ignored.

To find the resource curse cross-country regressions are employed to explain growth performance. You always need some measure of initial GDP since growth slows down as you get richer. But most resource abundant countries discovered their oil before 1960 or 1970, the typical years used for initial GDP. So resource abundance led to higher GDP but its effect in the regression is explained by initial income not natural resource wealth (no matter how mismeasured -- I leave that for another time).

This fundamental error pervades the analyses. You typically find that a country like Russia has very high corruption for its level of GDP and this is explained by its resource abundance. But if Russia had less resources it would have much lower GDP! The reason Russia is off the regression line is not that its oil makes it more corrupt but that its oil makes it wealthier than its institutions and other fundamentals would suggest. Take away the oil does not make it richer!

Energy Independence and Analysis

The revolution in production of unconventional oil and gas in the United States is no doubt an important development for the economy. But it also has been accompanied by a lack of analysis. Case in point, Sunday's NYTimes piece on the "Dark Side of Energy Independence."  The authors, editors at Foreign Affairs, argue that increased US production could lead to a 50% reduction in oil prices, and then analyze the effects of this on oil producers elsewhere.  They point out that:

lower energy prices will undermine the stability of the Persian Gulf monarchies, whose hefty oil revenues have allowed them to win their populations’ loyalties through patronage and a lack of taxation. These countries do not always share American values or help advance American interests, but anything that destabilizes them would create problems that Washington could not afford to ignore.        

What is amazing about their argument is that they never consider how oil producers will react to lower oil prices. They do not consider the impact of $50 per barrel oil on the profitability of unconventional producers. If prices fall in half which oil projects are likely to be cut back? Presumably those with the highest costs. 

Nor do they consider how OPEC producers might react to this increase in oil production from elsewhere. They could, cut back their production, as comments from Saudi oil minister, Ali Naimi, suggests. But if OPEC cuts back then why would prices fall in half? Alternatively, facing lower prices desperate countries might increase production causing a further fall in prices, as Michael Levi notes. 

But the key point to remember is that unconventional production of oil and gas is a response to high oil prices. As prices fall the projects that are cut back are those that have the highest marginal cost. Failing to consider this is an invitation to faulty analysis.

Energy Security vs Water Security

Interesting article in NYTimes on using fracking to unlock oil supplies. Although fracking uses up valuable water supplies,

The oil industry says any environmental concerns are far outweighed by the economic benefits of pumping previously inaccessible oil from fields that could collectively hold two or three times as much oil as Prudhoe Bay, the Alaskan field that was the last great onshore discovery. The companies estimate that the boom will create more than two million new jobs, directly or indirectly, and bring tens of billions of dollars to the states where the fields are located, which include traditional oil sites like Texas and Oklahoma, industrial stalwarts like Ohio and Michigan and even farm states like Kansas.

“It’s the one thing we have seen in our adult lives that could take us away from imported oil,” said Aubrey McClendon, chief executive of Chesapeake Energy, one of the most aggressive drillers. “What if we have found three of the world’s biggest oil fields in the last three years right here in the U.S.? How transformative could that be for the U.S. economy?”

But I wonder how much gain there is if switch from importing oil to importing water? Not that we can ever insulate ourselves from imported oil, there is not that much to frack. But even if there was, aren't supplies of water also important? Would politicians be so happy to have our water consumption decided by an Organization of Water Exporting Countries?

Don't Knock the Ryan Plan?

Joe Nocera tells us not to knock Paul Ryan. Not that he likes the plan itself:

The Ryan plan, which would give seniors a fixed amount they can use to buy health insurance, would undoubtedly shift the cost burden over time from the government to seniors themselves, making health care far less affordable for millions of people. Ryan says that “empowering” health care consumers will help control costs, but that’s absurd: Medicare itself has far more pricing power than the people who actually need treatment.

The first part of Nocera's critique is correct, the cost of health care is shifted to seniors themselves, but the second part makes no sense (though I have seen this before, see here). I wonder how people can hold such contradictory ideas in their heads at the same time? If you shift more of the costs to seniors, who have limited budgets, they will get less health care. If they pay less for health care, costs will fall. Of course so will the amount of health care provided. But you cannot deny that if people cannot afford healthcare they will buy less of it.

Indeed, that seems to be the biggest problem with the Ryan plan. It controls the costs of healthcare by forcing people to buy less than they need.

But then the confused Nocera argues that we should not scorn Paul Ryan. Because the costs of health care are real he argues that:

It would be nice if we could treat the Ryan plan not as an object of derision but as a launching off point for a serious debate. That way, maybe for once we could avert a crisis instead of acting shocked when it finally arrives.

But this seems odd to me. Why not let the Obama Plan be the start of a discussion to control Medicare costs? You don't want to scorn Ryan who argues that Obamacare destroys Medicare. But we should start the discussion with Paul Ryan?

Nocera is really confused.

Supermarkets and Schools

Greg Mankiw connects to this Don Boudreaux article in the WSJ asking what supermarkets would be like if they were run like public schools. Mankiw thinks the article is thought-provoking, so do I, but for opposite reasons I think. Have you ever seen what supermarkets are like in poor neighborhoods? Compare groceries and school in South-Central Los Angeles. The schools are better, much better, and that is saying something. They are even safer. For a study of groceries in South Central you can go here.

Of course there are plenty of good groceries stores in Brentwood and Beverly Hills. So what is the point that Boudreaux and Mankiw want to make. That we can have school choice and the affluent will get good choice and good schools, and the poor will get their education from bodegas and liquor stores? Do they think that the crime and violence, let alone lack of purchasing power, that inhibits supermarkets from moving to poor neighborhoods will not deter schools?

Playing with Fire

Pennsylvania Senator Pat Toomey puts in his two cents as dumbest legislator early in his term. With Congress playing fire over a debt ceiling bill, he calls for legislation to only pay interest on the debt. As this article in the NYTimes notes:

“I think the important thing to do would be to make it clear to markets that the government is not going to default on its debt,” said Senator Patrick Toomey, Republican of Pennsylvania, whose bill assigns priority to interest payments. “It would be easy, I think, to make it clear to the markets that they don’t have to worry about this.”

Toomey's plan to pay interest payments but not other government obligations -- such as wages -- seems as dumb politically as economically. After all, much of the debt is held by foreigners, so Toomey would pay off the Chinese before American citizens who toil for the public. I guess this fits with the basic Republican idea that interest recipients are more important than average Americans, but it is certainly playing with fire to do so. This would convert the government into a debt junkie who chooses each month whether to pay utilities or the rent and which creditors to hide from. Does Toomey really believe financial markets will still trust US debt under such behavior?

Greeks are Angry

Greeks are angry over the costs of reform. See this article in the Guardian.

A growing chorus of voices is urging the Greek government to restructure its debt as fears grow that a €110bn bailout has failed to rescue the country from the financial abyss and is forcing ordinary people into an era of futile austerity.

"It's better to have a restructuring now … since the situation is going nowhere," said Vasso Papandreou, whose views might be easier to discount were she not head of the Greek parliament's economic affairs committee.

Given the scale of protests to minor adjustments it is hard to see how Greece can make the big adjustments necessary to adjust their fiscal situation:

Tomorrow, in a clear sop to the thousands who have signed up to the "can't pay, won't pay" movement, the ruling socialists will announce reductions of up to 50% in road toll fees. As the nation struggles to rein in a debt of €340bn, the logic of appeasing protesters – an estimated 8,000 Greeks a day were refusing to pay tolls – has outweighed antagonising them further. "Our hope is that this will calm things down," the deputy transport minister Spyros Vougias said.

Last week, a man shot a bus inspector hired to crack down on fare dodgers after protesters stormed a police station, snatched hundreds of confiscated number plates and set light to thousands of fines. Days later thugs attacked Antonis Loverdos, the health minister, as he visited a hospital in Athens. In Patras, James Watson, the 83-year-old Nobel Prize-winning geneticist was also attacked as he prepared to give a speech at the city's university.

It is hard to see how Greece can adjust without haircuts from bondholders. Some trade between haircuts and real reforms might make it palatable. But that opens up a complex political economy problem for Europe, since there are other economies, notably Portugal and Ireland with similar, though right now more manageable, problems.
