st: Double hurdle model for Stata

["Olli-Pekka Ruuskanen" <opruuskanen@hotmail.com>]

Dear STATA community

Is there a program for estimating Double Hurdle model for STATA? This model 
was first proposed by Gragg (1971) and subsequently it has been used for 
example by Deaton and Irish (1984), Jones (1992) and Garcia and Labeaga 
(1996). It is an extension to Heckman’s model with selectivity, which 
explicitly models non-participation and potential participation apart from 
the observed participation.

None of my attempts to find it in any of the archives and sites have 
succeeded. I would be grateful for any information.

Yours Sincerely

Olli-Pekka Ruuskanen
