The Trouble with Stock Market Bubbles

  1. David DeRosa

Do stock market bubbles exist? David DeRosa, author of “Bursting the Bubble: Rationality in a Seemingly Irrational Market,” discusses some of the most famous bubbles – from Dutch Tulipmania in the 1630s to the Dotcom bubble of the late 1990s – and shares his conclusions on whether speculative bubbles exist in the stock market.

The Take 15 Series is a collection of illuminating, short conversations with noted economists, best-selling authors, leading researchers, and successful practitioners on topics ranging from geopolitics and whistleblowing to irrationality and outlooks.
