The 0th Law of Microeconomics and Macroeconomics

Any Microeconomic or Macroeconomic theory, principal or conjecture is explicitly forbidden from ignoring the principals and practices of accounting.

Any separation of "accounting practice" from "economic theory" will completely and totally void the economic theory, as any and all economic theory 'is based on the observation of the average and typical behaviors of masses of individual accounting decisions'.

Microeconomic or Macroeconomic theories, principals or conjectures can only follow after the 0th Law.
