Creating Variable - years since an event

[Ailbhe Br]

Hi there,

I have a panel dataset and wish to do a regression analysis that involves a variable, "Years since the Financial Crisis" (which refers to the most recent financial crisis of 2007).

I am looking for advice on how to code this.

Should I simply code all years as 0 up to and including 2007, and then 1 for 2008, 2 for 2009 etc? Or is there a better method?

Thanks in advance!

In turn you need to say more about your rationale for any such variable.

But something like

gen wanted1  = year - 2007

or

gen wanted2 = max(0, year - 2007)

might suit. Compare the comments at https://stackoverflow.com/questions/...since-an-event
