Japan's Bubble Wasn't Irrational: Why Optimists Drove Prices to Insanity
Think the Japanese asset bubble was just crazy speculation? Think again. This video breaks down the groundbreaking research by economist Robert B. Barsky (NBER, 2009) that flips the script. We dive into why most Japanese investors actually believed stocks were fairly valued at the peak in 1989, and how a mix of 'heterogeneous beliefs' and short-selling restrictions allowed only the most optimistic voices to set prices. You'll see survey data revealing that over 60% of Japanese pros thought the Nikkei was fine, while 75% of Americans knew it was a bubble—and why that gap matters. Plus, learn why this fragile market had to crash, and how the same dynamics play out in today's markets. No boring academic jargon, just the shocking truth about what really happened.
