Bennetts, Associate Director, Financial Regulation Studies, Cato Institute. In recent years, concerns have been raised about the potential market risks associated with high frequency trading and algorithmic trading in general. Proponents of high frequency trading suggest the practice is a contemporary tool that facilitates informational market efficiency and is capable of being regulated by the market and market participants. Opponents have argued that these practices create risk and require aggressive regulation. This discussion takes place against a backdrop of heightened regulatory scrutiny given the recent push by the Securities and Exchange Commission to monitor high-frequency trading and related practices, such as the creation of dark pools, more closely.

In his new book Free to Move: Foot Voting, Migration, and Political Freedom, Ilya Somin explains how broadening opportunities for foot voting can greatly enhance political liberty for millions around the world, often more effectively than voting at the ballot box. People can “vote with their feet” by participating in international migration, choosing where to live within a federal system, and making decisions in the private sector. These three types of foot voting are rarely considered together, but Somin explains how they have important common virtues. He also pushes back against the most common objections to expanded migration rights, including the claim that the self‐​determination of natives gives them the power to exclude migrants. By making a systematic case for a more open world, Free to Move challenges conventional wisdom on both the left and right. Professors Peter Margulies and Bryan Caplan will provide additional insights, comments, and criticisms. Please join us for a timely and lively discussion, moderated by Cato's David J. Bier.
