Financial Risk and Regulation explores a broad range of topics in finance, financial regulation, compliance, and risk management. These include, among many others, regulatory arbitrage, risks created by a firm’s business model, conflicts of interest, risk appetite as the governing metric in risk management, the distinction between risk and uncertainty, and model risk and model risk management. My understanding of these and other subjects constantly evolves and deepens as I teach them and learn from my students at UCLA and the University of Chicago. Also included are posts from my previous blog, Compliance Today: A Blog on Financial Institution Compliance, hosted by the Chicago-Kent College of Law. The final post for that blog is dated December 4, 2017.
