'In a geographical area that uses a monetary system with a commodity as money, and prices set by weight of the commodity, such as with the gold standard, purchases of ‘imports’ (at ‘world’ prices) from other areas would result in a reduction in the money supply (weight of gold) in the Buyer’s area if not replenished by sales to other areas. A reduction in supply would make the money more valuable (basic ‘supply and demand’ would cause a higher purchasing power per unit of weight), and thus prices set by local suppliers would go down and become more competitive with imports. Purchases of imports would decline, and exports would increase.'
