Which economic policy favors domestic interests at greater total cost to trading partners, a pattern associated with mercantilism?

• A. Mercantilism
• B. Deflation
• C. Liquidity Trap
• D. Inflation

Answer: (A)

Mercantilism is about using government power to tilt trade in favor of the home country, often by raising barriers to imports or subsidizing exports to build a trade surplus. It aims to accumulate wealth through a favorable balance of trade, even if that means raising costs for trading partners—tariffs, quotas, and import restrictions are classic tools that protect domestic producers while limiting foreign access. The idea is that strengthening domestic interests comes at the expense of others, making the total costs of trade higher for partners.

By contrast, the other options describe macroeconomic conditions rather than policy patterns designed to advantage one country at others’ expense: deflation is a falling overall price level, inflation is a rising price level, and a liquidity trap is a situation where monetary policy becomes ineffective at stimulating demand.
