Book excerpt: From social media to mortgage-backed securities, innovation carries both risk and opportunity. Groups of people win, and lose, when innovation changes the ground rules. Looking beyond formal politics, this new book by Cristie Ford argues that we need to recognize innovation, and financial innovation in particular, as a central challenge for regulation. Regulation is at the leading edge of politics and policy in ways that we have not yet fully grasped. Seemingly innocuous regulatory design choices have clear and profound practical ramifications for many of our most cherished social commitments. Innovation is a complex phenomenon that needs to be understood not only in technical terms, but also in human ones. Using financial regulation as her primary example, Ford argues for a fresh approach to regulation, which recognizes innovation for the regulatory challenge that it is, and which binds our cherished social values and our regulatory tools ever more tightly together.
