MIT's Josh Angrist introduces differences-in-differences with one of the worst economic events in history: the Great Depression. • Economists still argue about the causes of the Great Depression, but most agree that a key piece of the puzzle was an epidemic of bank failures. Over 9,000 banks failed from 1930 to 1933! • Could the Federal Reserve have prevented this catastrophe? • At the time, regional Federal Reserve branches had considerable policy independence. Some branches helped troubled banks with “easy money”. Others did not, following a “tight money” policy. • Metrics wizards Gary Richardson and William Troost used differences-in-differences to analyze a natural experiment in Mississippi, where one half of the state had tight money while the other half had easy. What did they find? • This introduction to differences-in-differences covers the following: • Bank failures during the Great Depression • Easy versus tight monetary policies; moral hazard • Parallel data trends • Calculating the treatment effect • Assumptions for a valid differences-in-differences analysis • *INSTRUCTOR RESOURCES* • Troost/Richardson paper: https://www.journals.uchicago.edu/doi... • Econometrics test bank: https://mru.io/kt2 • High school teacher resources: https://mru.io/o15 • Professor resources: https://mru.io/t0f • EconInbox: https://mru.io/sm5 • *MORE LEARNING* • Try out our practice questions: https://mru.io/wfd • See the full course: https://mru.io/469 • Receive updates when we release new videos: https://mru.io/7g2 • More from Marginal Revolution University: https://mru.io/c30
