I hope this email finds you well. I am writing to seek your guidance on a methodological question regarding my research.
I am currently working on a comparative analysis where I aim to assess the coefficient differences between two distinct groups, like conducting subsample regression (e.g., comparing state-owned enterprises with non-state-owned enterprises).
Specifically, I am considering using the gsynth package to estimate the coefficients separately for each group and then comparing them. However, I am unsure if this method is valid or if there are better alternatives for conducting sub-sample comparisons.
I would greatly appreciate your expertise and insights on this matter.
