I am working on my master dissertation and I am struggling in interpreting my results properly. I am looking for a good source (book, paper, or website) that provides explanation on how to interpret the results (coefficients, standard errors, etc.) of dynamic panel models.
I am using Stata to fit a dynamic panel model using GMM estimation methods. My problem is twofold:
First, I don't understand why the following was done, and how the findings can be interpreted: Multiplying the coefficient with the standard deviation of the variable in the sample to see the impact of the variable. What would the result of the above operation tell us?
Second, one of the papers I read using this method (Acemoglu et al. 2008) stated, "Although the pooled OLS estimate of the independent variable is quantitatively small, the two standard error bands of the fixed effects estimators almost exclude it." What does it mean? How do I get this?
