Mercantilism is a form of economic system and nationalist economic policy that is designed to maximize the exports and minimize the imports of an economy. It seeks to maximize the accumulation of resources within the country and use those resources for one-sided trade.
The concept aims to reduce a possible current account deficit or reach a current account surplus, and it includes measures aimed at accumulating monetary reserves by a positive balance of trade, especially of finished goods. Historically, such policies may have contributed to war and motivated colonial expansion. Mercantilist theory varies in sophistication from one writer to another and has evolved over time.
