Local Average Response Functions


This page contains Matlab code to compute least squares approximations to a local average response function, as defined in Abadie (2003), "Semiparametric Instrumental Variable Estimation of Treatment Response Models," Journal of Econometrics, vol. 113(2), 231-263. The second step can be specified as linear or as probit (see equations (7) and (8) in the article). The first step is carried-out parametrically, using a Probit estimator. Standard Errors are calculated using the techniques in section 4.3.1 in the article.

For usage, open Matlab in a directory that has access to the files and type "help cls" or "help clsprobit" on the command line.
