Hi David, Here are the other references: Hoxby, C. M. (2000). Does Competition Among Public Shools Benefit Students And Taxpayers. American Economic Review, 90(5). pp. 1209-1238. Hastings, J. S., Kane, T. J., & Staiger, D. O. (2005). Parental Preferences and School Competition: Evidence from a Public School Choice Program. NBER Working Paper Series #11805. Hastings, J. S., Kane, T. J., & Staiger, D. O. (2006). Preferences and Heterogeneous Treatment Effects in a Public School Choice Lottery. NBER Working Paper Series #12145. I'm pretty sure the Hastings et al papers have been published elsewhere, but that will at least get you the relevant information to move forward with things.

More recently, Justine Hastings along with Tom Kane and some other folks have done a fair amount of modeling of school choice in the Charlotte-Mecklinburg school district. I know both of the papers I am thinking of are available via NBER and can send full citations later if you'd like. Do you have good parental education/income data? One of the things that Hastings found was that school choice decisions were a function of parental income, education, and employment (e.g., parents with higher incomes tended to choose schools that were higher performing regardless of location while parents with lower incomes tended to choose schools that were closer to the home). If nothing else, those papers could give you a good idea of how the issue has been approached in the past. >>> >>> HTH, >>> Billy >>> >>> Sent from my iPhone >>> >>> On May 6, 2013, at 7:33, David Torres <writeon4truth2@msn.com> wrote: >>> >>>> Thanks for you response, Austin. >>>> >>>> To be clear, though, I am using data from a large school district and am using as my outcome scores on the Stanford 10 math and reading assessments, so no plausible values. My explanatory variable of interest is whether a child's parents exercised choice to send the child to a school other than the zoned school (0 = no, 1 = yes). It's this explanatory variable that I'm focusing on as one that needs to be instrumented, given the differential likelihood of exercising choice deriving from parents of various education levels, density of neighborhood, etc. I'm only using the 2008 kindergarten cohort and am following these children across five years. The boundaries remain constant across the years, as far as I can tell. >>>> >>>> As an aside, I do have addresses for all families in the district and will be geocoding these soon. I then plan to use the -vincenty- command to calculate the distance to the nearest school (which will also be geocoded) to which a student is not zoned. This will be included as an additional control. >>>> >>>> -- >>>> >>>> David Diego Torres, PhD >>>> NSF SBE Postdoctoral Research Fellow >>>> Houston Education Research Consortium >>>> Rice University >>>> 6100 Main Street, MS-28 >>>> Houston, TX 77005 >>>> Phone: 713-348-2984 >>>> Email: ddtorres at rice dot edu >>>> >>>> >>>> ---------------------------------------- >>>>> Date: Mon, 6 May 2013 10:18:40 -0400 >>>>> Subject: Re: st: Instrumental Variables approach using -xt- for three-level growth model >>>>> From: austinnichols@gmail.com >>>>> To: statalist@hsphsun2.harvard.edu >>>>> >>>>> David Torres <writeon4truth2@msn.com> >>>>> You don't specify, but I assume you have 5 plausible values drawn from >>>>> a posterior distribution on achievement from some standardized test as >>>>> your outcome variable, and school type attended as your explanatory >>>>> variable of interest--none of the variables you cite satisfy an >>>>> exclusion restriction, as all would be expected to have direct impacts >>>>> on achievement.

I'd prefer to do this in HLM7, but I'm not sure if the program allows for this more complex model setup. Anyway, I know Stata has the -xtivreg- command. Is there something similar for mixed effects models, i.e., -xtivmixed- perhaps? If not, how can I accomplish my aim using what's available in Stata. (I do have the Rabe-Hesketh & Skrondal texts.) >>>>>> >>>>>> I am instrumenting for the likelihood of parents exercising choice to send their children to a school outside the zoned school area. Obviously, self-selection is an issue here, but proxies that might explain the likelihood of choice are, and this list is by no means exhaustive, number of older children in the household, maternal education, or percent of persons over 18 with a bachelor's degree...or something like that.
