# Balance of Trade ## Definition The difference between the value of a nation's exports and imports over a given period. Under the mercantile system, a favourable balance (exports exceeding imports) was believed to increase national wealth by bringing more gold and silver into the country, while an unfavourable balance was thought to drain wealth away. ## Source Chapter Book IV, Chapter 1 ## Context Smith critiques the mercantile obsession with the balance of trade, showing how merchants and governments wrongly believed that a country's prosperity depended on maintaining a favourable balance. He demonstrates that this focus on precious metals rather than actual production and consumption led to misguided policies like export bounties and import restrictions. ## Economic Domain Exchange ---
