Hi,
I have conducted a Difference-in-Difference regression to study the impact of establishing of a factory on the housing prices in a certain region. I have used log-prices as my dependent variable. I get parallel trends, and a significant effect post-treatment.
However, when doing the same DID-regression with non-log prices, I get parallel trends, but no significant effect post-treatment.
Should I include both of these regressions in my thesis for the sake of transparency and discussion? Or should I use only the one with logged prices, since similar studies often only look at logged prices?
