Professor Niessner’s main research interests are behavioral finance, financial social networks, and online media. In my recent academic work, I apply methods from linguistic psychology to identify fake news on knowledge sharing platforms, and to examine their impact on financial markets. In my other work, I use opinions from a social network of investors, to develop a new measure of investor disagreement and examine the extent to which different investment philosophies lead to more volatility in the stock market. My research has been featured in the Financial Times and the Wall Street Journal. Dr. Niessner received her BA and PhD in Economics from the University of Chicago.
