Description: The principle of comparative advantage is fundamental to determination of the pattern of trade among nations. David Ricardo was the economist who coined this term. Opportunity cost, stated briefly, is the benefit foregone for undertaking an activity. So, if a country has a lesser value for its resources in the alternative use, it can most efficiently employ resources in this activity. This is what comparative advantage means. Example: Two goods are produced, say wine and wheat, using only one input, i.e. labour. Suppose Nation A requires 10 and 5 units of labour to produce one unit of wine and wheat, respectively, whereas, Nation B requires 10 units of labour each.
