I’m working on a DHS methodology paper specifically focused on estimating the effects of time-varying regressors of interest on child HAZ. I have a weird question/request, and figured since you put this up on the blog, it was worth asking about.

What happens to your HAZ point estimates as you add your increasingly flexible age specifications? You say that other specifications perform poorly, and my guess is that that point estimate bounces around a good bit…but I find they tend to converge with a few different really flexible age specifications (I have some spline and non-parametric specs I like at the moment). I’m sure you understand why (the underlying HAZ-age profile* is interacting with the exact distribution of child ages for each regionXsurvey, I think), but I’m trying to figure out how big a problem the HAZ-age profile thing is in other people’s work, and I’d be curious to know how sensitive your estimates are.

Figured that since this was such a weird “Hi, nice to meet you, your work is really cool and I’m working on something related” I’d just comment here instead of sending you an email. But feel free to write me back if you’re interested.

*by HAZ-age profile I mean the mean HAZ by age graph, which drops like 1-2 sds in the first few years of life in an entirely non-linear manner.

Hurricane risk actually improved the education of the house hold.

It seems that students can make the decision who is teaching better themselves. Fristly, I think it is a great idea to have AP courses. Assuming that value of college is not a degree, but acquired knowledge, smarter kids who take these AP courses can choose whether to use it for credit (when they think it was good enough), or they can take the same course at the university (where they will have advantage of seeing the same stuff before). So why not let the market forces decide… And I am moving for more math at school!
