Unintended Consequences

From The Nation (via Core Econ):

Thanks to an obscure tax provision, the United States government stands to pay out as much as $8 billion this year to the ten largest paper companies. And get this: even though the money comes from a transportation bill whose manifest intent was to reduce dependence on fossil fuel, paper mills are adding diesel fuel to a process that requires none in order to qualify for the tax credit. In other words, we are paying the industry--handsomely--to use more fossil fuel. "Which is," as a Goldman Sachs report archly noted, the "opposite of what lawmakers likely had in mind when the tax credit was established." ...

The origins of the credit are innocent enough.... [The 2005 transportation bill] included a variety of tax credits for alternative fuels such as ethanol and biomass. But it also included a fifty-cent-a-gallon credit for the use of fuel mixtures that combined "alternative fuel" with a "taxable fuel" such as diesel or gasoline....

"You use the toilet every day," said one hedge fund analyst who's been closely following the issue. "Imagine if you could start pouring a little gasoline into the bowl and get fifty cents a gallon every time you flushed."...

Whether or not Congress gets around to turning off the spigot, the episode is a useful reminder of the persistently ingenious ways the private sector can exploit even well-intentioned legislation. Considering that the success of the Treasury's recently announced plan to rescue the financial sector depends, in part, on the private sector not gaming the rules, the black liquor story seems particularly germane.
