Principle
Keep Income Growth Supported By Productivity
Formulation
Do not treat income growth as healthy when it persistently outruns productivity growth.
Use When
Use this when judging whether an expansion is sustainable or merely supported by credit, asset prices, policy stimulus, or temporary demand.
Do Not Use When
Do not assume every short-run divergence is dangerous. The principle matters when income growth remains unsupported by productivity long enough to affect competitiveness or repayment capacity.
