  • Estimating with substitution (accounting conservatism)

    Hi Statalisters,

    Hope you are doing well. I try to estimate the accounting conservatisim following Mozaffar Khan and Ross L. Watts (2009). The main objective is to get the G_Score and C_Score (as showd below).
    I'm strugle because there is substituion. Here are the equations, and as you see E (4) the it is at cross sectional annual.

    For my variables compared to those in the photo,

    Earn = X
    Ret= R
    D=D
    Size=Size
    Lev=Lev
    M/B=MTB

    For more information about what these models, I posted below that part.

    I would be gratful if someone help me to do the code for my target.
