We welcome Professor Maureen O’Hara, the Robert W. Purcell Professor of Finance at Cornell. Our conversation begins with a conversation about her foundational work on market microstructure theory and moves on to a discussion about the effects of ETFs and high frequency trading on market stability. We delve into the nuances of ethical behavior on Wall Street, explored in her most recent book “Something For Nothing,” and ponder what new regulatory mechanisms may be necessary as artificial intelligence and machine learning technologies continue to evolve and dominate market trading.
