要旨:
After the great financial crisis of 2007–2009, central banks were handed a macroprudential mandate to contain systemic risks, a mandate seen as endangering their independence due to expected distributional conflicts. At the same time, depoliticization through scientific expertise was largely foreclosed, as systemic risk was a largely undefined concept. This paper focuses on how central banks dealt with this conundrum. It examines the scientific debate on systemic risk and macroprudential regulation post-crisis, focusing on the debate’s impact on final regulation. Employing author-topic-modeling on a unique dataset of 2397 published economic papers on the relevant topics, we detect the formation of a new alliance between central bankers and academic economists working jointly on developing systemic risk measures. Centered around a hinge of systemic risk contribution by individual banks, this new alliance expresses itself by incorporating the macroprudential concerns of practitioners into abstract market-based systemic risk measures. These measures develop incrementally, using and repurposing techniques from financial economics pre-crisis to legitimize and justify macroprudential interventions post-crisis. This alliance allows us to account for the incremental change witnessed post-crisis and point to its potential for long-term fundamental change.
