Interpretation and Relevance of Long Run Coefficients in System GMM Regressions

[Prateek Bedi]

Hello,

Hi,

I estimate the following system GMM model based on a panel dataset of 1696 firms across 16 years.

Group variable: CompanyID                    Number of obs         =      6991
Time variable: Year                          Number of groups      =       671

Moment conditions:     linear =      53      Obs per group:    min =         1
                    nonlinear =       0                        avg =  10.41878
                        total =      53                        max =        15

                                       (Std. Err. adjusted for 671 clusters in CompanyID)

I use the following command to calculate long run coefficient for promoter.ownership (i.e. WPromoterS) which comes out to be -0.02565***.

nlcom (_b[ WPromoterSharesin1 ])/(1-_b[ L.CashHoldings1 ])

I am curious to know and understand the relevance and interpretation of this long run coefficient of promoter.ownership (i.e. WPromoterS).

Any help in this regard is highly appreciated.
