This text is built on the belief that to understand the international economy, students need to learn how economic models are applied to real world problems. It is true what they say, that ”economists do it with models.“ That's because economic models provide insights about the world that are simply not obtainable solely by discussion of the issues. A variety of international trade models including the Ricardian, Heckscher-Ohlin, and the monopolistic competition models are presented.
