Terms of trade refers to the rate at which a country's exports can be exchanged for its imports. In other words, it is the value of a country's exports relative to its imports. A country's terms of trade are influenced by factors such as global market conditions, exchange rates, and the supply and demand for its exports and imports. If a country's terms of trade are favorable, it means it can purchase more imports for the same amount of exports, which is beneficial for its economy. On the other hand, if its terms of trade are unfavorable, it means it has to export more to afford the same amount of imports, which can be detrimental to its economy.
