| After reading this book no one will ever complain that macroeconomics lacks micro foundations. This book first explains the microeconomics of intertemporal goods and labor markets and goes on to create an intertemporal general equilibrium economy (with two periods for simple exposition). Then Wiliamson shows how growth theory and business cycle theories are applied in this general equilibrium economy. This is by far the most fun and understandible way to teach undergraduates about growth and business cycles at the intermediate level. Williamson also lays out "stylized facts" of the business cycle, including comovements, and he critiques different business cycle theories based on whether they can replicate those comovements in the data. This book comes closer than any other intermediate text to replicating how modern macroeconomics is done. Ch 8 which explains Solow and endogenous growth models is by far the most understandible and educational of any text on the market, since Williamson does the models in discrete time rather than continuous time. If you're a professor that wants to teach undergraduates growth theory and/or growth dynamics SO THAT THEY REALLY UNDERSTAND THEM DEEPLY and ENJOY THE LEARNING EXPERIENCE, this is the book to assign. |
