st: Formal question: transformation of variables and diff-in-diff

[Raquel Rangel de Meireles Guimarães <raquelrguimadem@gmail.com>]

Hi all

I would like to ask you a simple but formal question:

I observe a variable X at two points in time to treatment and control 
groups, which were determined by common support (pscore algorithm). I 
got an estimate of the diff-in-diff W.

If I do Y = X/100, match again treated and control within the common 
support, will I find the same groups? If so, the estimate of 
diff-in-diff in this new scenario will be simply W/100?

Best,

Raquel
