I don't believe your approach produces consistent point estimates, nor
good interval estimates. There is no canned program for QR with
endogenous variables, that I know of, but GMM and other optimization
problems are now easy to program yourself in Mata (I think Kit Baum's
forthcoming book will provide examples).  See e.g.
