In my understanding, a pooled OLS regression in STATA is provided through the command reg or regress (which is completely the same). However, it does not seem that this approach takes the actual panel structure into account. Nevertheless, the researchers of the mentioned paper utilize exactly this term “pooled (panel) regressions” (p.24).xtdpdgmm estimates a linear (dynamic) panel data model with the generalized method of moments (GMM). The main value added of the new command is that is allows to combine the traditional linear moment conditions with the nonlinear moment conditions suggested by Ahn and Schmidt (1995) under the assumption of serially …Create ID for panel dataset. 10 Apr 2017, 04:48.
