The Bank for International Settlements (BIS) and the Bank of Korea (BoK) jointly organized a conference on macroprudential regulation and policy in Seoul, Korea, on 16-18 January 2011. The conference aimed to bring academics together with researchers at central banks and other public institutions to present and discuss ongoing theoretical and empirical work in the field. In response to their call for papers, the organizers received more than 75 submissions from central banks, public agencies, supranational organizations and academic institutions. From these, a selection committee from the BIS and the BoK chose 12 papers organized around the following four themes: systemic risk; financial system procyclicality; macroeconomic impact studies and early warning indicators; and (iv) effective implementation of macroprudential policy.
