Why Fuel Efficiency Advances Haven't Translated To Better Gas Mileage
greenrainbow tips an article about a research paper from an MIT economist that attempts to explain why technological advances in fuel efficiency haven't led to substantially better gas mileage for the average driver. Quoting:
"Thus if Americans today were driving cars of the same size and power that were typical in 1980, the country’s fleet of autos would have jumped from an average of about 23 miles per gallon (mpg) to roughly 37 mpg, well above the current average of around 27 mpg. Instead, Knittel says, 'Most of that technological progress has gone into [compensating for] weight and horsepower.' ... Indeed, Knittel asserts, given consumer preferences in autos, larger changes in fleet-wide gas mileage will occur only when policies change, too. 'It’s the policymakers’ responsibility to create a structure that leads to these technologies being put toward fuel economy,' he says. Among environmental policy analysts, the notion of a surcharge on fuel is widely supported. 'I think 98 percent of economists would say that we need higher gas taxes,' Knittel says."
I think 98 percent of economists would say that we need higher gas taxes Knittel says.
93% of all statistics are made up. 99% of economists know that.
Adverse conditions to not favor top heavy rear wheel only SUVs.
One of the US crash safety standards required by the NHTSA that adds weight and expense to new vehicles is for "unrestrained drivers", despite the fact that under 10% of US drivers go un-belted these days. The punch line is that the IIHS found the NHTSA test not very useful, because un-bented passengers often aren't held in place in front of the intended safety devices.
Keep in mind that the US Gas tax is used to pay for highways, that it's not indexed to inflation, and it was last raised early in Clinton's first term. Which means it doesn't actually cover the cost of maintaining highways.
The result is that my, non-car-using, ass has to pay income taxes to subsidize all these people who love their cars so much, but if I dare to ask them to pay for a train or another bus I'm breezily told "nobody will use that."
Because they're so simple. They would also allow our highway fund to be self-sustaining, which would mean that we could stop subsidizing it with income taxes from people who don't drive. Things like tax credits and CAFE Standards can be gamed.
In the long-term taxes also have the advantage of getting people used to $6 Gas. Oil production isn't rising. Indian and Chinese guys are finally getting rich enough to drive home for the holidays, which means it's inevitable that gas will go up. Period.
But since everybody pays the gas tax all the time nobody wants to be responsible for raising it, therefore we get a mess.
I'm not necessarily against taxing gasoline. However, before we start using a gasoline tax as a tool to force people to behave a certain way, maybe we should consider eliminating the billions of dollars of subsidies given to the oil industry so that we can see the *true* price of gasoline?

All the posters here keep crying about how "the open market" has failed, but we aren't in an open market, so that is nonsense.
Taxes are for funding the govt services we all need...that should be it...period.
People should be free to choose to drive and spend in the fashion they wish.
Taxes weren't passed to allow a 'chosen' few to dictate citizen behavior....

The increase in gas prices hasn't drastically changed what vehicles we buy. Many of those that really would rather buy more efficient vehicles can't afford them, and are stuck with older ones, so the economists would just be hurting the poor.
As consumers shouldn't we choose what vehicle economies we use? Where I live, SUVs are all over. But, it makes more sense. Adverse conditions favor SUVs. An economist, you would think, would say people buy what they want.
Few people really *need* a 4WD SUV or even an AWD car.
When I lived in the northeast, I commuted entirely with a front wheel drive car. I put on snow tires in the winter, and never got stuck (or in a winter time accident). For 3 winters, I moonlighted as a snow-plow driver for a local business, so part of my commute meant driving in conditions that many people stayed home in (and I regularly saw 4WD vehicles that had run off the road). As long as the roads had less than 8 inches of snow, I was good to go - beyond that I'd need more ground clearance than my car provided. I did resort to chains on a few icy days.
Smart driving and snow tires are much better than blind trust in an SUV. And unfortunately, many SUV drivers do appear to use that blind trust rather than good driving skills.
4 wheel drive (or AWD) only helps you move forward, you already have 4 wheel braking, and for most of us, it's the braking that's more important when driving in adverse conditions.
Now it's possible that you have a need to travel on unmaintained roads to your cabin in the woods, for that I'll grant you that an SUV may be helpful (but not infallible, get a Sno-cat if you *have* to get somewhere in the snow)
Whatever you think..taxes should not be used for behavioral manipulations.

So you advocate rolling back tobacco taxes?
Speaking for myself, absolutely. Taxes used for social engineering are wrong. Period.
The purpose of taxes are to pay for the government. If the specific role of fuel taxes are to pay for the roads, then raising them with the idea of forcing 'economy' is wrong.
It is also amazing to me that some of the same people who will practically demand such taxes in the name of the environment will turn right around and argue that a flat tax is wrong because it hurts the poor. As if the higher fuel tax doesn't?

That's cute. You think the market will naturally do what's right instead of what's profitable. :)
Take a look at http://en.wikipedia.org/wiki/Sumptuary_tax
One of the original reasons given for a tax like that:
The sale of alcohol necessitates higher costs in policemen and prisons, Pigou argues, because of the crime associated with alcohol. In other words, the net private product of alcohol businesses is peculiarly large relative to the net social product of the same business. He suggests that this is why most countries tax alcohol businesses.
In the case of oil, there are many costs beyond that of simply producing the oil, refining it and transporting it. The most obvious is the cost of maintaining trade relations with many OPEC countries. Most industrial countries would have no need of Middle Eastern countries if they weren't sitting on a sea of oil, and could leave them to their own devices like countries in Africa and South America.
There's the cost of CO2 emissions, although many people are still burying their heads in the sand about this.
Then there's the cost of transitioning from oil. We could wait until we simply run out of cheap oil before doing anything, or we can preemptively start the long process of transitioning away from oil as a primary source of fuel used for transportation.
I don't know, ask all the overweight people out there what's wrong with a junk food or fast food tax?
The cost of obesity on society is 100 times the cost of smoking on society, and we're footing the bill just the same as with smokers. Ask yourself this: if a parent allows their child to eat themselves into their own grave, does that constitute child abuse? Should the state be allowed to remove the child from a home that does not make sure their children are of a healthy body weight? If a child is severely underweight, the state will absolutely take a child into custody, it happens all the time. But overweight? Never.
So how do you feel about a crappy food tax? Because honestly, I find that nine times out of ten, the person that is all about the smokers tax thinks the shitty food tax is just going too far. That's not to say that it is always true, but it usually is. Smoking is considered the dirty habit, but cramming 10 servings of powdered mini donuts in your mouth in a single sitting isn't? Eating 3 Double Cheeseburgers for lunch with an extra large fries and half gallon of coke isn't a dirty habit, too?
And then there's the excuses "Why should I be punished for eating fast food once in a while?! I am not overweight!!" That's a bullshit excuse because not everyone that smokes gets fucking lung cancer, but they all pay the tax just the same, don't they? So the fact that a person is healthy and only eats a little candy is immaterial.
Mind you, I'm not a smoker, but I used to be, and it really was the increased cost of the things that encouraged me to quit...$7 a pack when I finally managed to lock myself in the house for 3 days without cigarettes and get off of them once and for all. I just find it funny how hypocritical most people are when it comes to smokers, and how easily they ignore their own bad habits. Human nature, I guess...
Whatever you think..taxes should not be used for behavioral manipulations.
I would argue the exact opposite. Taxes are the only way to fairly manipulate behaviour. Should it be in the overall interest of everyone to reduce our rate of fuel consumption, a tax is the only way to go. What are the alternatives, make gas guzzling vehicles illegal? Or how about requiring automakers make specific types of cars.
A tax on gas will change national behaviour without placing limits on what we can do. Want to drive a Hummer? - just be ready to pay for it when you fill up. The tax acts as an incentive for people to minimize fuel consumption. This is better then the alternative as people retain the freedom to do drive and purchase whatever vehicle they want.
People should be free to choose to drive and spend in the fashion they wish.
Yes, but when those "fashions" have a negative impact on their neighbours then it is time to apply a tax. The true cost of a product is not measured with just dollar signs. For example, the environmental repercussions of consuming a product are almost never part of the original purchase price. If the "invisible hand" is going to work correctly, monetary values for those repercussions must be artificially added in the form of a tax.
If you do not allow society to lay the cost of externalities onto the perpetrators, you invariably produce a tragedy of the commons. You can, in principle, use Ron Paul's approach and simply make people pay for polluting private property - i.e. if you produce CO2 that turns up in the air over my property, you are trespassing and need to pay damages. But that is technically implausible for shared resources like air, water, and the ecosystem as a whole. Thus, using taxes to approximate the externalities is a reasonable approach. Of course we can only approximate the cost, but that is no different than with any other financial planning, wether by government or in the private sector. Very very few projects end up exactly on budget. That's not a reason not to plan, nor is it a reason not to act.
