It follows the fundamental assumptions of stablepreference and rational choice in Mill Paradigm and Marshall Paradigm, but it adds the Coase Revolution of transaction costs constraint. As a result, its explanation capability is beyond SamuelsonParadigm and New Keynes Paradigm. So, Economic Explanation Paradigm is the same with MillParadigm, Marshall Paradigm, Samuelson Paradigm and New Keynes Paradigm, which should beconsidered to be an important synthesis in the history of economic thought.展开更多
