Greenspan goes green

Alan Greenspan quoted in the New York Times:

In late September, as he spoke to a group of business executives in Massachusetts, a question was posed as to whether he’d like to see an increase in the federal gasoline tax, which has stood at 18.4 cents a gallon since 1993. “Yes, I would,” Mr. Greenspan responded with atypical clarity. “That’s the way to get consumption down. It’s a national security issue.”

The article also gives publicity to Greg Mankiw's Pigou Club. Excellent!
