Let's Hear it for the Letter "Y"

The Wall Street Journal ran a recap of a an article in BusinessWeek about women facing a much higher rate of inflation than men. It's an interesting idea, instead of lumping price data for all consumer goods, break it out by the gender of the likely consumer. On the other hand, a study like this is really no better than its assumptions (how are "auto parts and repairs" strictly male consumer goods?), so we probably ought not read too much into this report.
