Assistant Professor of Economics and Finance

My research is in decision theory, mainly in fields related to financial theory including asset pricing, portfolio selection and option pricing. My main interest is in decision making under uncertainty, focusing on measuring ambiguity, perceived probabilities and their implications for finance.

Ambiguity Index

The figure below plots the degree of ambiguity (based only on intraday price data) in the U.S. stock market. I computed this ambiguity index using the measure I developed in my paper.
