A Probe into the Unification of Micro-Macro-Economics: Arrow-Debreu-MundellFleming Model as a Standard Model

For unifying micro-economics and macro-economics, demand-supply relation, marginal effect and multiplier model construct three keys. As aggregate demand (AD) – aggregate supply (AS) can be approached by multiplier model and marginal effect is also connected to multiplier one, it is revealed that micro-Arrow-Debreu model can be combined with macro-Mundell-Fleming model, which is suggested to become economic standard model.
