Hi,

I am going to make a dummy Ii ( Em (i)<= Em) that selects firms whose employment (Em(i)) is below a certain threshold, the median of employment over the sample.
firms ID: NPC_FIC
Employment: Em

Code:

end

Listed 100 out of 24599 observations

First, I made the median:
Code:
egen median_Employment = median( Employment)
Now, I need to make a dummy that selects firms whose employment is below the median of employment over the sample.
Any suggestion is appreciated.

Cheers,
Paris
