We have designed this book to be a supplement to Robert J. Barro’s Macroeconomics,which
is the textbook that is used in introductory macroeconomics courses at the University of
Chicago. In teaching these courses, we have found that Barro’s treatment of the subject
does not make use of the mathematical skills of our students. In particular, Barro relies
almost exclusively on economic intuition and graphs to elucidate his subject. Since our
students are familiar with calculus, we are able to work out formal models. This almost
always allows greater concreteness and concision.
We have attempted to align our chapters with those in Barro’s textbook. Sometimes our
chapters present mathematical versions of the models that Barro introduces in his corre-
sponding chapters (as in Chapters 2 and 19). Other times, our chapters contain material
that extends his work (as in Chapters 5 and 17). Throughout, we have tried to add value to
the treatment in Barro’s book and to minimize redundancy. For example, we have n
