This paper argues that the basic concept of comparative advantage, used in international trade theory to establish choices of commodities exported, can also be used to explain choice of technology by a firm. A firm with a current leading position in a given technology may spurn a new technology, which is developed by a currently lagging firm, leading to future overtaking.
