The article explores how historical events like the Great Depression in the 1930s have been used to predict and plan for future financial crises. By studying past crises in the 1960s and 1980s, researchers show how policymakers and academics learn from history to prepare for potential economic disasters. The 2008 financial crisis highlighted the importance of looking back at historical events to avoid repeating mistakes and better understand the impact of economic theories. By using the past as a guide, policymakers can anticipate and plan for future crises, rather than just reacting to them when they occur.
