Book Talk


The New Stock Market: Law, Economics, and Policy


11 December 2023 (Monday), 12:30 – 1:30 PM
Academic Conference Room, 11/F Cheng Yu Tung Tower, HKU




The U.S. stock market has been transformed over the last twenty-five years. Once a market in which human beings traded at human speeds, it is now an electronic market pervaded by algorithmic trading, conducted at speeds nearing that of light. High-frequency traders participate in a large portion of all transactions, and a significant minority of all trade occurs on alternative trading systems known as “dark pools”. These developments have been widely criticized, but there is no consensus on the best regulatory response to these dramatic changes. The book offers a comprehensive new look at how these markets work, how they fail, and how they should be regulated. It draws on the informational paradigm of microstructure economics to highlight the crucial role of information asymmetries and adverse selection in explaining market behavior, while examining a wide variety of developments in market practices and participants. The result is an account of the stock market’s regulatory framework, fundamental institutions, and economic dynamics, combined with an assessment of its various controversies. The New Stock Market covers a wide range of issues including the practices of high-frequency traders, insider trading, manipulation, short selling, broker-dealer practices, and trading venue fees and rebates. The book illuminates both the existing regulatory structure of our equity trading markets and how we can improve it. More information about the book is available here.
