I listen to the Planet Money podcast every week, and am a big fan of the show. William Luther, an assistant professor of economics at Kenyon College, is too, and has used the show in his classes to teach principles of macroeconomics. Luther has argued that this approach has increased understanding and engagement among his students.
Alex Tabbarok put together this servicey list of which Planet Money episodes you should listen to if you want to focus on any specific principle. Want to learn about monetary policy? Listen to the “Gold Standard” episode! How about saving, investing, and the financial system? This episode with Carl Richards might interest you.
