2 stage regression

[H_G]

Hello,

I am running a logit regression, while because my dependent variable is affecting one of my independent variable , which is as what I understood a problem of endogeneity, I have to use instrumental variable, which I have to estimate by OLS.

would you please help me how can I do it in SAS?

Thanks

for more explanation;my model is like following:

adoption_new_technology(dummy)= a1*(age)+a2*(education)+a3*(job)+a4*(interest_buy_insurance)

here if some one is adopted to new technology, it will affect his decision on buying insurance. here we have indogeneity in " interest_buy_insurance "
