Gresham’s Law

Gresham's law describes incentives to circulate money overvalued at an official or imposed rate while retaining or diverting money undervalued at that rate relative to its market value. Its applicability depends on the valuation and circulation arrangements, not simply on the coexistence of currencies.

Gresham's law is associated with monetary arrangements that treat different monies as equivalent at an official or imposed rate despite differences in their market value. People have an incentive to spend the overvalued money and retain, export, or otherwise use the undervalued money. The fixed valuation condition is central; merely having two currencies does not establish the result.

A broader analogy is defensible only when the same structure can be identified: unequal underlying value, equal credited value, and a reason to withhold the better option. Ordinary competition in which low quality wins, or meetings crowd out focused work, may involve entirely different mechanisms. Name those mechanisms directly when the monetary structure is absent.

When to use it

When analyzing monetary circulation under fixed valuations or critically testing whether a proposed nonmonetary analogy preserves the relevant mechanism.

How it can help

Identify the imposed equivalence and alternative valuations before predicting what will circulate. Use organizational analogies only when they preserve a comparable reward structure and withholding incentive.
