    and this simultaneous equations system
    Code:
    xtreg y x2 s1 c.x2#c.s1, fe robust 
    xtreg M x2 s1 c.x2#c.s1, fe robust  
    xtreg y x2 s1 M c.M#c.s1, fe robust
    The purpose is to test whether the product of the coefficient on `x2' in the second equation and the coefficient on `c.M#c.s1' in the third equation is statistically significant? Any suggestions? Thanks.
