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.

WebLin et al. 36 developed a dynamic game model in a low-carbon supply chain that consists of a single manufacturer and a single retailer. Then, he also explored the complex dynamic characteristics of pricing decisions and carbon reduction strategies in the supply chain, focusing on the impact of retailers’ social preferences on pricing decisions. WebResearch overview - Dynamic Effects. Dynamic effects are kinetic phenomena associated with the motions and momenta of atoms that cannot be explained using transition state theory. Dynamic effects cannot be explained using transition state theory, so they violate the paradigm we use to understand reactivity and selectivity in organic chemistry.
