New Directions for Understanding Systemic Risk: A Report on a Conference Cosponsored by the Federal Reserve Bank of New York and the National Academy of Sciences
finance.1 Presenters from the natural and mathematical sciences and the engineering disciplines provided examples of tools and techniques used to study systemic collapse in interactive systems in nature and engineering. These presentations are summarized in Chapter 3. Similarly, research economists presented studies of systemic risk in cross-border investments, liquidity risk, and the payments system, and these presentations are summarized in Chapters 2 and 4. To provide a context for the discussions, risk managers at large finance institutions described how systemic risk and shocks in the financial system affect trading activities.
TRANSITIONING FROM A BANK-BASED TO AMARKET-BASED FINANCIAL SYSTEM
Financial market practitioners began the conference by highlighting various aspects of systemic risk and systemic events in the financial system. The topics of the presentations ranged from historical systemic episodes, such as the liquidity crisis of 1998 and the failure of LTCM, to risk assessment techniques, such as value-at-risk (VaR) analysis and scenario analysis. Charles Lucas of AIG (since retired), a member of the National Research Council’s Board on Mathematical Sciences and Their Applications, introduced the first session by asking the fundamental question: What is systemic risk?
According to Lucas, economists’ theoretical understanding of systemic risk stemmed from the experience of the Great Depression and specifically from John Maynard Keynes’s interpretation of that experience in GeneralTheory of Employment, Interest, and Money. Keynes aimed the formulation of his “general theory” at capturing the dynamics that allowed an economy to transition to an inferior but stable equilibrium, in the process overturning the normal full-employment equilibrium that defined classical models. During the Great Depression, the economy underwent a shock that was sustained by sympathetic movements throughout the financial system—a sequence of events that has come to be called “contagion.” Because of policy missteps and a feedback loop with the financial system, the real economy settled into a persistent state of underutilized resources and unemployment. Despite structural changes since that time, the idea of a feedback loop between the financial and real sectors of the economy that leads to an inferior equilibrium with negative consequences for the real economy remains pertinent to current analysis of financial stability.
That system has changed dramatically since the Great Depression, as described in the conference background paper on the evolution of
