In May of 2005 I reported about a study by Emily Oster which cast doubt on an argument I had made in a series of earlier posts. Then in November of 2006 I learned of a new study casting doubt on Oster’s work. Well, now it seems that Emily Oster went back and dug up some new data to disprove her own initial study. Good for her.
