Explain the concept of balance of trade.

The concept of balance of trade refers to the difference between the value of a country's exports and the value of its imports over a specific period of time, typically a year. It is a key component of a country's balance of payments, which measures all economic transactions between a country and the rest of the world. A positive balance of trade, known as a trade surplus, occurs when a country's exports exceed its imports, resulting in a net inflow of money. Conversely, a negative balance of trade, known as a trade deficit, occurs when a country's imports exceed its exports, resulting in a net outflow of money. The balance of trade is influenced by various factors such as exchange rates, tariffs, trade policies, and the competitiveness of a country's industries.
