Is Caroline Hoxby’s defense of school vouchers hopelessly flawed in its data work? I doubt it, but I have not been following this debate. Here is the recent and excellent WSJ article on the spat; the link does not require a subscription. Excerpt:
Five years ago Harvard’s Caroline Hoxby, a rising star in economics, wrote a paper that reached an unusual conclusion: Cities with more streams tended to have schools with higher test scores.
Today her work is a widely cited landmark in the fierce national debate over free-market competition in public schools. And it’s at the center of a bitter dispute with another economist that is riveting social scientists across the country.
Her adversary is Jesse Rothstein, a young professor at Princeton, who says her study is full of flaws. In a rebuttal to her critic, Dr. Hoxby wrote of his work: "Every claim is wrong." She has also accused him of ideological bias. Dr. Rothstein, in turn, says she resorts to "name-calling" and "ad hominem attacks" on him.
