Before revision:  The paper  establishes the mathematical underpinning of the static equilibrium, dynamicequilibrium and structural equilibrium. The generic model and its equilibria are then extended to economies with complicated economic structures consisting of hierarchical production, composite consumption, technology adoption and innovation, infrastructure, and economic and political institutions.
After revision:  The paper establishes the mathematical underpinning of the static , dynamic, and structural equilibria. The Ramsey growth model and its equilibria are then extended to economies with complicated economic structures consisting of hierarchical production, composite consumption, technology adoption and innovation, infrastructure, and economic and political institutions.
