Driving home yesterday, I heard a radio host talking up the merits of a 4 day work week. The main argument seemed to be: 20% less driving means 20% less fuel consumption.
I know I tend to think like an economist, but doesn't anyone else drive more on the weekend than during the week? I know I do. I don't have any evidence handy, but I would guess a 4 day work week would have no net effect on total fuel consumption--and possibly even increase it.
Thoughts?
