(The increase for some groups was very small and for others very negative.) If Sarah's right and this wasn't an apples-to-apples comparison, then perhaps it is more favorable than it appears.

I suppose there was some way of addressing the problem of colinearity?

I wanted to say something about "silver standard" and the inherent dubious quality of econometric models, but I didn't want to seem overcritical of the study which did after all return some encouraging results. Two things stand out: 1) There's no reason to trepidatiously embrace the positive results of a study, the very conclusions of which are questionable and 2) yes, the calls for oversight likely are premature. But at least charter schools are getting more media attention. Thanks, Sarah.

From what I've read about it in the newspapers, it looks like it didn't. If I'm right, it's not an apples-to-apples comparison. That's one of the distinctions of Caroline Hoxby's work (and of research by other economists like Roland Fryer). Unless their research meets that standard, the authors' calls for more charter school oversight are premature.
