Mc Laren’s Economics of International Trade reviews economic models and present theories to explain the benefits and goals of trade between countries, generally assume a minimum exposure to Principles of Microeconomics. It is rigorous and unique in its presentation of stories about countries in today’s world first. Following the real-world stories, the text also offers standard theoretical constructs and economic models. Mc Laren uses an "inverse" approach where students are presented first with an ongoing set of events in an other country, followed by the models and theories in an applied setting that are needed to get through the course.
