3.0 The Role of Gold: A Critique of Monetary Orthodoxy
To understand the inter-war policy failures, Heilperin argued for a fundamental re-evaluation of the role of gold. He moved the analysis away from a fixation on the metal’s intrinsic properties and toward a focus on the institutional arrangements that defined its monetary function. This conceptual shift is essential for understanding the flaws in contemporary quantitative theories and for grasping the true, and often misunderstood, nature of the gold standard.
3.1 The Critical Distinction: Gold Currency vs. Gold-Standard Currency
A primary source of confusion was the failure to distinguish between a true gold currency and a currency merely based on a gold standard. Heilperin insisted on a sharp distinction between these two arrangements, as summarized in the table below.
| All-Gold Currency | Gold-Standard Currency |
| This is a system where only gold coin circulates as the medium of exchange. | This is a system where paper and bank money (notes, cheques) form the primary circulating medium. |
| Goods are paid for with a commodity money (gold), and prices are rigorously “gold prices.” | Currency is merely convertible into gold at a specified price, often with restrictions (e.g., only for large bars). |
| The money supply is identical to the physical stock of monetary gold. | Money has been “de-materialized.” Prices are “nominal” and expressed in abstract monetary units. |
| The link between gold and prices is direct and automatic. | The relationship between the currency and the gold standard can be “rather loose,” mediated by central bank policy and the credit system. |
This distinction reveals that under a modern gold standard, money is not a commodity but an abstract claim. The system is not automatic; it is a managed paper currency attached to a gold base through specific institutional rules.
3.2 The Fallacy of “Purchasing Power of Gold”
This conceptual clarification directly challenges the widely used but imprecise notion of the “purchasing power of gold.” While this term has a clear meaning in an all-gold currency system (where it is synonymous with the purchasing power of money), its application to a gold-standard system was, in Heilperin’s view, a source of profound error.
He specifically critiqued the authoritative definition provided by the Gold Delegation of the Financial Committee of the League of Nations, which stated:
“The term variations in the purchasing power of gold is therefore synonymous with the term variations in the levels of prices in countries on the gold standard.”
Heilperin condemned this as a “logical salto mortale” and “entirely mistaken.” It incorrectly conflates a currency based on gold with a currency consisting of gold. The price level in a gold-standard country is expressed in its nominal, de-materialized currency units (e.g., pounds, dollars), not in units of gold. Equating the two was to fundamentally misunderstand the institutional nature of the modern monetary system.
This flawed concept of “gold prices” led directly to influential but erroneous quantitative theories that attempted to link the physical supply of gold directly to price levels.
