compare betas of two different regression analyses

[Sanaullah Farooq]

Hi
I ran two different OLS regressions as follows:
reg Y1 X1 + X2
reg Y2 X1 + X2

beta coefficient of X1 from my first regression is 0.06 and from second regression is 0.01. I want to know whether these two beta coefficients are statistically different. is it possible to do that? also is it possible to test whether in fact beta coefficient of X1 is my first equation is larger than the second? thanks

How about something like this?
