Now lets see if he'll do the same when his girl proposes the same thing...

I'm calling you OUT Paul Krugman!

GASOLINE TAX FOLLIES

SYNOPSIS: Ending a gas tax is subsidizing OPEC. It solves nothing for Americans

Teachers of economics cherish bad policies. For example, if New York ever ends rent control, we will lose a prime example of what happens when you try to defy the law of supply and demand. And so we should always be thankful when an important politician makes a really bad policy proposal.

Last week George W. Bush graciously obliged, by advocating a reduction in gasoline taxes to offset the current spike in prices. This proposal is a perfect illustration of why we need economic analysis to figure out the true "incidence" of taxes: the people who really pay for a tax increase, or benefit from a tax cut, are often not those who literally fork over the cash. In this case, cutting gasoline taxes would do little if anything to reduce the price motorists pay at the pump. It would, however, provide a windfall both to U.S. oil refiners and to the Organization of Petroleum Exporting Countries.

Let's start with why the oil cartel should love this proposal. Put yourself in the position of an OPEC minister: What sets the limits to how high you want to push oil prices? The answer is that you are afraid that too high a price will lead people to use less gasoline, heating oil and so on, cutting into your exports. Suppose, however, that you can count on the U.S. government to reduce gasoline taxes whenever the price of crude oil rises. Then Americans are less likely to reduce their oil consumption if you conspire to drive prices up -- which makes such a conspiracy a considerably more attractive proposition.

Anyway, in the short run -- and what we have right now is a short-run gasoline shortage -- cutting gas taxes probably won't even temporarily reduce prices at the pump. The quantity of oil available for U.S. consumption over the near future is pretty much a fixed number: the inventories on hand plus the supplies already en route from the Middle East. Even if OPEC increases its output next month, supplies are likely to be limited for a couple more months. The rising price of gasoline to consumers is in effect the market's way of rationing that limited supply of oil.

Now suppose that we were to cut gasoline taxes. If the price of gas at the pump were to fall, motorists would buy more gas. But there isn't any more gas, so the price at the pump, inclusive of the lowered tax, would quickly be bid right back up to the pre-tax-cut level. And that means that any cut in taxes would show up not in a lower price at the pump, but in a higher price paid to distributors. In other words, the benefits of the tax cut would flow not to consumers but to other parties, mainly the domestic oil refining industry. (As the textbooks will tell you, reducing the tax rate on an inelastically supplied good benefits the sellers, not the buyers.)

A cynic might suggest that that is the point. But I'd rather think that Mr. Bush isn't deliberately trying to throw his friends in the oil industry a few extra billions; I prefer to believe that the candidate, or whichever adviser decided to make gasoline taxes an issue, was playing a political rather than a financial game.
