This Vox EU Course Companion, the first in the series, is a collection of carefully selected Vox columns designed to supplement Mankiw’s Macroeconomics textbook. Vox Course Companions provide relevant examples of economic theory in action and offer thought-provoking perspectives on arguments that come up time and again in exam-style questions. They bring together analyses of economic phenomena by leading economists as they happened, while applying and comparing the suitability of competing economic theories.
