Dear Stata Pros ,

Being interested in the effect of the share of women in board position on return on assets of a company.
Running a regression with adding the following control variables:
Dummies for industry, region, and year, log total assets, the size of the board, demographics of the workforce (like age) and of the board members.

My question:

Why (and in which direction) could the coeffcient on the share of female board members may be biased (Distinguishing between time-varying and time-invariant unobservables)
What do you think?


Thank you very much for your help!

Kind regards
Mimi

Miriam:
welcome to this forum.
Queries like yours are virtually impossible to reply positively, as:
1) you don't shate what you typed and what Stata gave you back (as reminded by the FAQ): hence, interested listers has no chance to see what the (potential) issues with your data are;
2) it is not clear why the coefficient of female board should be biased;
3) moreover, it is not clear the theoretical ground that should support any possible bias of the abovementioned coefficient.

I would recommend you to read and act on the FAQ and re-think your post so that it can be addressed by anyone who may have interest in replying. Thanks.
