Definition
Closed Economy is an economic system that does not engage in international trade. All production, consumption, and investment occurs domestically, with no imports or exports.
Why It Matters
Understanding closed economies helps economists and policymakers analyze the effects of domestic policy without the influence of foreign trade. While rare in practice, it provides a theoretical baseline for examining production, consumption, and savings behavior within a self-contained system.
Example
If a country produces all the goods and services it consumes and does not trade with other nations, it operates as a closed economy. Government policy, household spending, and business investment determine economic growth without influence from foreign markets.
