Why is the gold standard rarely used today, and what macroeconomic policy challenges does it raise?

• A. It fixes the money supply to gold reserves, restricting monetary policy and reducing ability to respond to demand shocks; deflation risk and policy inflexibility.
• B. It allows unlimited monetary policy freedom
• C. It eliminates currency risk completely
• D. It ensures central banks set interest rates at zero

Answer: (A)

The main idea here is that a gold standard ties the money supply to gold reserves, which keeps the central bank from freely adjusting the amount of money in circulation. Because the currency must be exchangeable for a fixed quantity of gold, policy makers can’t easily expand or contract the money stock in response to shifts in demand for money or to stabilize the economy. This constraint makes it hard to cushion the economy during downturns, and if gold grows slowly relative to the economy, prices and wages can fall, producing deflation.

Two big macro challenges come from this setup: first, there’s policy inflexibility in the face of demand shocks, since money growth is effectively constrained by gold flows and mining rates rather than by deliberate stabilization. second, there’s deflation risk, because the price level can fall if the money supply doesn’t keep pace with real economic growth, leaving borrowers worse off and complicating recovery.

The other statements aren’t accurate because they describe scenarios that a gold standard does not deliver: it does not grant unlimited monetary policy freedom, it does not eliminate currency risk completely (the exchange rate and price level can still be unstable under the regime), and it does not require central banks to set interest rates at zero.
