I have a panel data containing earnings of opposite sex twins and would like to estimate
the gender gap using the Blinder–Oaxaca decomposition using R.
1) How to make the Blinder–Oaxaca decomposition for panel data in R? The package oaxaca does not work for panels. Does somebody know of a work made in R that I can use as a model?
2) How to account for the fact that I have a sample of twins and therefore each pair of twins share many unobservable caracteristics? The Mincerian wage regressions will not account for that.
