Whereas Volume One: Microeconomics dealt with the optimizing individual, Volume Two: Macroeconomics explains the factors that affect the economy of an entire country, and indeed the planet. It explores the two big concerns of macroeconomics: how economies grow and why economies collapse. It illustrates the basics of the labor market and explains what the GDP is and what it measures, as well as the influence of government, trade, and technology on the economy. Along the way, it covers the economics of global poverty, climate change, and the business cycle. In short, if any of these topics have cropped up in a news story and caused you to wish you grasped the underlying basics, buy this book.
