Hello All,
I need a help as I am stick in a situation while dealing with instrumental variables
In one of my regrssions I have used lagged values of my independent variables as instruments
Now those independent as well as lagged are interaction terms.
Like:
Dep variable = β0 + β1(dominant CEO) i,t-1 +β2DomCEOi,t-1*CEOfin i,t-1 +β3 DomCEOi,t-1 * CEOedu + control variables
Now, I use lagged values of these two interaction terms
Domceo * ceofin
Domceo*ceoedu
As instruments
The lagged values are showing significant relationship in the first stage of our 2sls regression with our endogeneous regressors but I am getting ceofin and ceoedu are also becoming significant in the first stage.What to do here?
Any help will be appreciated.
