Professor Jeffrey Wurgler's research on stock market bubbles is cited
— August 11, 2015
Excerpt from MarketWatch -- "...we have no choice but to conclude that we’re not in another bubble like it [the Internet bubble]. That...is the conclusion I reached upon grading the current market according to five dimensions of investor sentiment that were devised by the authors of perhaps the leading academic study of stock market bubbles. Those authors are finance professors Jeffrey Wurgler of New York University’s Stern School of Business and Malcolm Baker of Harvard Business School."
