Robert Barro's Macroeconomics has become the classic textbook presentation of the equilibrium approach to macroeconomics. In its first four editions, this book has shown undergraduates how market-clearing models with strong microeconomic foundations can be used to understand real-world phenomena and to evaluate alternative macroeconomic policies. Moreover, a single, unified framework works as well for short-term business fluctuation as for long-term economic growth. This latest edition includes the most recent theoretical and empirical developments in economic growth, recent evidence on the macroeconomics of labor markets and public finance, and up-to-date results on the interplay between nominal and real variables.
