Hi,

I'll use IV regression for some endogeneity robustness checks, but I'd like to mention other ways to mitigate the problem.

I've seen 3SLS and simultaneous equations mentioned a few times, but is there any difference between that and IV?

3sls is essentially IV applied to a system of simultaneous equations while also taking account of correlation between the equations.

Thanks. I found an EXCELLENT paper on endogeneity in a corporate finance context that gave me my answer and much more. I recommend it:
