I have binary dependent variable and one of my independent variable is endogenous. I also want to control for group level heterogeneity using fixed effect.

How can I use instrument variable approach to control for endogeneity and fixed effect to control for group level heterogeneity together in a single model.

Is it possible to do this using SAS.

I will also really appreciate if I somebody can provide me some references on this topic

I don't think this is straightforward. Angrist and Krueger in their survey paper argue that 2SLS is still a robust means of estimating an average treatment effect when
the dependent or IV variable is binary. However, they don't discuss fixed effects models.

variables and the search for identification: From supply and demand to
natural experiments' Journal of Economic Perspectives 15:69-85.
