How Do You Handle Endogeneity in Panel Regression Models? or What Are the Best Practices for Fixed Ef

Endogeneity? Ugh. If IVs are hard to find, try control function approaches or even just lagged dep vars. Not perfect, but better than nothing.

GMM is awesome for big panels, but for small ones, it’s like using a sledgehammer to crack a nut.

Stata’s `xtivreg` is my go-to for IV in panel regression.
