Hi all,

I am using Stata 15 on Windows.

I have data on houses and study the effect of mixed use on house prices with a hedonic fixed effects model, using the reghdfe command.
In short, I regress log house price on a MIX dummy and a number of structural house characteristics like number of rooms etc.
With fixed effects I control for time trends (through year) and location (through street).

I got the tip to check if my fixed effects are doing their job, by regressing log house price on MIX only and a second time with also the other house variables included (both regressions with year and location fixed effects). If the coefficient for MIX is relatively the same this should indicate that the fixed effect effectively control for unobserved variables.

I attached the results of the two regressions. My question is now, is there a way that I can see how similar these coefficients for the MIX dummy are? I read something about suest, but that this cannot be used in combination with reghdfe. Or is it something I can deduct based on the s.e.? Also, the R² is of course way lower for the model which includes only MIX, so I was wondering if this approach makes sense in the first place? I am fairly new to econometrics so thoughts are welcome.


Thank you for reading,
