Subject | st: Dynamic panel model? |
Date | Sun, 3 Nov 2013 14:44:51 +0000 |
Dear Statalist, My data: unbalanced firm panel data (six periods) dependent variable: firms´sales share with new products variables of interest: firms´sales share with new products(t-1) and firms´sales share with old products(t-1) I want to examine the influence of firms´ sales share with new products in the former period compared to the influence of firms´sales share with old products in the former products on firms´sales share with new products now. My goal is to compare the effects of the lagged variables (based on coefficients, marginal effects or whatever). I am wondering which econometric model implemented in Stata would be appropriate to do so. Any ideas? Thank you for consideration.
