It is characterized by the influence of previous values of the dependent variable on its present value, and by the presence of unobservable explanatory variables. The term “dynamic” here means the dependence of the dependent variable on its past history; this is usually used to model the “state dependence” in economics.

WebThe generalized method of moments is mainly used in panel data econometrics to estimate dynamic models (M. Arellano and Bond 1991; Holtz–Eakin, Newey, and Rosen 1988). yit = ρyit − 1 + β⊤xit + μi + ϵit. The model is first differenced to get rid of the individual effect: Δyit = ρΔyit − 1 + β⊤Δxit + Δϵit.
