The folks over at Lawyers, Gun$, and Money are chiding me for ignoring (or, as they say, never having heard of) positive externalities. A couple of days ago, I criticized a NYT editorial calling for the federal government to “throw its weight behind” private efforts to develop alternative fuels. My main point was that the best thing the government could do would be to let energy prices rise in response to forces of supply and demand. High prices, I argued, have spurred — and will continue to spur — private investment in alternative technologies.

It’s a strange day when the New York Times advocates corporate tax breaks. It’s an even stranger day when I dissent from that recommendation. Well, today must be a strange day indeed, for they did, and I must.

An article from yesterday’s W$J sheds some light on the organic community’s anger over Wal-Mart’s decision to begin selling organic products. A few weeks ago, I accused Wal-Mart’s critics of wanting to keep price-sensitive consumers out of the organic “club.” The article in yesterday’s Journal suggests that that’s part of the story, but that the critics might also have a legitimate gripe. Examined closely, though, even that concern is unfounded.

Marty Feldstein has an interesting idea about how to reduce America’s oil consumption, but I’m not quite ready to sign on.

In an op-ed in yesterday’s WSJ, Feldstein proposed a “cap and trade” system for gasoline. Under the proposed system, the government would set a limit on the amount of gasoline Americans could purchase annually and would then allocate rights to purchase that amount of gasoline.

The New York Times is worried about Wal-Mart’s plan to sell organic food. One would think that fans of organic would be happy about this development. It means that organic products will be available more cheaply at Wal-Mart, which is planning to sell organic products for just 10% more than conventionally grown food, and it’s almost certain to lower organic food prices elsewhere. First, competition with Wal-Mart will lower prices. In addition, Wal-Mart’s entry into the organic sector will expand organic production, thereby permitting producers to achieve greater economies of scale.

There have been some pretty stupid ideas floating around about how to deal with this purported gasoline crisis we’re experiencing. (See, e.g., here.) Here’s one that might sound crazy at first, but is, I submit, crazy like a fox.

Back in February, I criticized the SEC’s rules regarding how energy companies must disclose their oil reserves in securities filings. My main point was that the conservative way the SEC measures reserves is quite different from the measurement approach the oil companies themselves take when deciding how to invest billions of their own dollars.

Today’s Heard on the Street column in the W$J reports that utilities are moving away from low-sulfur coal in favor of the dirtier, high-sulfur variety. This might seem odd, given that the Clean Air Act operates on sort of a “ratchet” principle — i.e., when air quality improves, degradation is generally forbidden. One might expect that, absent some change in relative prices, the trend would always be toward cleaner-burning fuels.

In a recent speech at the Brookings Institution, Senator Richard Lugar (R-IN) bashed what he called “a laissez-faire energy policy that relies on market evolution.” Under such a policy, he says, “life in America is going to be much more difficult in the coming decades.” He insists that “[w]hat is needed is an urgent national campaign led by a succession of presidents and Congresses who will ensure that American ingenuity and resources are fully committed to this problem.”
