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.
