st: Canned Bivariate Model

[Alex Rutt <amr59@cam.ac.uk>]

Hi,

I am trying to run a canned version of Abowd and Farber (1982) bivaraite 
probit model with partial observability. I am doing this to try to 
correct for selection bias when looking at the effects of IMF programs 
on economic growth. The basic problem is that although I can run a 
standard bivaraite probit model with partial observability I cannot 
adapt it so that I can run the canned version of the model. i was 
wondering if anyone knew how to adapt it so that I could run the canned 
version. Furthermore I need to run this regression so that I can create 
hazard rates for the Heckman Selection model, I have worked out how to 
create hazard rates when looking at a simple regression, but I can't 
seem to create two different hazard rates, one for each of the 
regression results from the bivariate probit model. Any help would be 
most appreciated.

Thanks,

Alex
