We deliberately avoided dividing the text into two parts because we found that many students are confused by the often inconsistent approaches of the two ‘subdisciplines’ of economics. We set out to create a course that is internally consistent. But, if your course structure is to teach microeconomics only, The Toulouse School of Economics and the Lahore University of Management Sciences use The Economy as its introduction to microeconomics. This course might teach Unit 1 and Units 3 to 12, with the remaining weeks of the course devoted to a combination of Unit 2 with capstone Unit 21, or capstone Units 19 or 20. A one-semester introduction to macro based on the CORE text has been taught at Sciences Po, Paris and Middlebury College, Vermont, US. A possible configuration of such a course is Units 1 and 2, 6, 9 and 10, and 13 to 17, plus a selection of capstone Units 18-22, possibly including the material on disequilibrium dynamics from Unit 11.
