Hello, all. I have completed a very rough draft of a working paper that uses the CHOPIT model (estimated in gllamm) to examine the possibility of what is referred to in the education policy literature as the "rose-colored glasses" effect--parents reporting higher levels of satisfaction with a school solely or partially as a justification for the effort expended in the choice process. Using both a Bayesian hierarchical measurement model and the CHOPIT approach, I find that the opposite effect is true: parents who choose are actually tougher graders for their new school than they should be. The paper, "Evaluating the Rose-Colored Glasses Effect: Do Parents Who Choose Have a Biased Evaluation of their Child's School," is online at www.sinc.sunysb.edu/Stu/roseglasses2.pdf. While I realize that the subject matter is a bit outside the focus of most subscribers to this list, I would welcome any comments on the implementation of the CHOPIT model. I should point out that my next step is to estimate the full multiple measures model (and improve the presentation of results) and that Jonathan Wand has been extremely helpful in supporting the Anchors R code that I hope to switch to!
