The nature and significance of intra-industry trade

In this article, Roy Ruffin gives an overview of intra-industry trade for the generalist. Intra-industry trade represents international trade within industries rather than between industries. Such trade is more beneficial than inter-industry trade because it stimulates innovation and exploits economies of scale. Moreover, since productive factors do not switch from one industry to another, but only within industries, intra-industry trade is less disruptive than inter-industry trade.
