Mercantilism Mercantilism was a sixteenth-century economic philosophy that maintained that a countrys wealth was measured by its holdings of gold and silver (Mahoney, Trigg, Griffin, & Pustay, 1998). This recquired the countries to maximise the difference between its exports and imports by promoting exports and discouraging imports. The logic was transparent to sixteenth-century policy makers-if foreigners buy more goods from you than you buy from them, then the foreigners have to pay you the difference in gold and silver, enabling you to amass more treasure.
