Economic interdependence is to depend on others for goods.
This is viable when the market is free and variable costs are considered.
Step-by-step explanation:
Economic interdependence is a concept in free market economies where when one country cannot manufacture things that it needs it will import them while exporting the things it can manufacture well to a large amount.
This means that all sort of manufacturing is done to meet the needs all over the world and one place need not produce everything it will need as far as manufacturing goes. This makes the process more efficient and more products are produced as they are made by nations that can make them well.
