Step-by-step explanation:
The nation is said to have a trade deficit when the value of its imports exceeds the value of its exports. A trade deficit occurs when a country imports more goods and services than it exports. For example, if a country imports $1 million worth of goods and services from other countries but only exports $800,000 worth of goods and services, it has a trade deficit of $200,000.
