Under a gold standard of the kind analyzed by Hume, describe how balance of payments equilibrium between two countries, $A$ and $B$, would be restored after a transfer of income from $\mathrm{B}$ to $\mathrm{A}$.

Key Concepts

Balance of Payments Equilibrium

A state where a country’s international receipts and payments are balanced, meaning that its import and export transactions, along with other financial transfers, occur in a sustainable and stable manner over time. Under a gold standard, imbalances trigger gold flows, which automatically work to restore equilibrium between countries.

Price Level Adjustments

The economic response whereby changes in the domestic money supply, caused by the influx or outflow of gold, affect the general price level. A decrease in gold reserves leads to a contraction in money supply and falling prices, making a country’s exports more competitive, while an increase in gold reserves causes rising prices, reducing competitiveness. This interplay under a gold standard ensures that imbalances are corrected over time.

Gold Standard

A monetary system in which the value of a country’s currency is directly linked to a specified amount of gold, ensuring that currencies can be exchanged for gold at fixed rates. This system inherently ties money supply to the country’s gold reserves, making international flows of gold a crucial mechanism for settling balance of payment imbalances between nations.

Specie-Flow Mechanism

The automatic adjustment process described by Hume in which a deficit or surplus in trade leads to corresponding outflows or inflows of gold. When a country experiences a net outflow of gold, its money supply contracts, lowering domestic prices and thereby increasing exports while reducing imports—a self-correcting mechanism that restores balance in international trade.
