Nothing real deep here--sometimes I just like to point out examples of basic economics--and brag about my kids.
I was flipping through the channels late last night after a long night at the softball fields--after an unnamed pitcher who happens to be the oldest daughter of an Env-Econ co-founder threw a 1-hitter to advance her team to the championship game of the I-270 (Columbus metro area) 10 and under travel fastpitch softball league--when I saw a new commercial. It was a series of people standing at gas pumps bemoaning high gas prices. As the commercial progresses, the people start to reveal that the way they cope with the higher gas prices is to buy cheaper stuff...at Wal-Mart. See...that's econ 101.
