Abstract
The Covid epidemic had a large impact on economic activity. In contrast, the dramatic decline in mortality from infectious diseases over the past 120 years had a small economic impact. We argue that people's response to successive Covid waves helps reconcile these two findings. Our analysis uses a unique administrative data set with anonymized monthly expenditures at the individual level that covers the first three Covid waves. Consumer expenditures fell by about the same amount in the first and third waves, even though the risk of getting infected was larger in the third wave. We find that people had pessimistic prior beliefs about the case-fatality rates that converged over time to the true case-fatality rates. Using a model where Covid is endemic, we show that the impact of Covid is small when people know the true case-fatality rate but large when people have empirically-plausible pessimistic prior beliefs about the case-fatality rate. These results reconcile the large economic impact of Covid with the small effect of the secular decline in mortality from infectious diseases estimated in the literature.

Der Staat und die Banken: Bankenregulierung im Kontext dynamischer Entwicklungen und unter Berücksichtigung indirekt betroffener Akteure

No. 7,

Abstract
Finanzmarktkrisen verursachen in der Regel hohe Kosten. Banken müssen stabilisiert werden, um einen Zusammenbruch des Bankensystems zu verhindern, was immense Kosten für den Staat bedeuten kann. Ebenso kommt es im Zuge von Finanzmarktkrisen zu einem starken Rückgang der wirtschaftlichen Aktivität, der im Vergleich zu gewöhnlichen Rezessionen länger anhält. Die Finanzmarktkrise hat dies ein weiteres Mal verdeutlicht und eine Phase der signifikanten Verschärfung der Regulierung und Aufsicht von Banken eingeleitet. Die Legislative hat das »Window of Opportunity« gut genutzt, und sowohl auf nationaler als auch auf europäischer Ebene wurden neue gesetzliche Grundlagen für eine stärkere Regulierung des Bankensystems erfolgreich eingeführt. Ein erster Erfolg des neuen regulatorischen Umfelds zeigte sich während der Corona-Pandemie, in der das Bankensystem stabil blieb. Dies wird auch durch die aktuell steigenden Eigenkapitalquoten und vergleichsweise niedrigen Ausfallraten im Kreditportfolio der Banken deutlich. Hervorzuheben ist außerdem, dass nicht nur auf nationaler Ebene Anstrengungen unternommen wurden, das regulatorische Umfeld für Banken zu verbessern, sondern dass es auch auf Ebene der Europäischen Union (EU) gelungen ist, mit dem »Single Rulebook« einen einheitlichen regulatorischen Rahmen zu schaffen. Dies wirkt Verschiebungen von Risiken innerhalb der EU entgegen. Trotz dieser Erfolge und positiven Entwicklungen darf nicht übersehen werden, dass sich durch staatliches Eingreifen und die Einführung neuer Regulierungsvorschriften nicht nur der betroffene Sektor, also die Banken, anpassen. Es kann auch zu Auswirkungen auf verschiedenste Akteure kommen, die direkt oder indirekt mit dem Bankensystem interagieren. Zudem kann es im Anpassungsprozess zu dynamischen Effekten kommen. Im Beitrag gehen wir auf zwei ausgewählte Aspekte ein, welche in diesem Zusammenhang von der Legislative zu beachten sind.
Der Beitrag ist Teil des Artikels “Die Zukunft des europäischen Finanzsystems – zwischen Risiken und mangelnder Wettbewerbsfähigkeit?“, erschienen in: ifo Schnelldienst, 2024, 77, Nr. 07, 03-36.

Risky Oil: It's All in the Tails

NBER Working Paper,
No. 32524,
2024
Abstract
The substantial fluctuations in oil prices in the wake of the COVID-19 pandemic and the Russian invasion of Ukraine have highlighted the importance of tail events in the global market for crude oil which call for careful risk assessment. In this paper we focus on forecasting tail risks in the oil market by setting up a general empirical framework that allows for flexible predictive distributions of oil prices that can depart from normality. This model, based on Bayesian additive regression trees, remains agnostic on the functional form of the conditional mean relations and assumes that the shocks are driven by a stochastic volatility model. We show that our nonparametric approach improves in terms of tail forecasts upon three competing models: quantile regressions commonly used for studying tail events, the Bayesian VAR with stochastic volatility, and the simple random walk. We illustrate the practical relevance of our new approach by tracking the evolution of predictive densities during three recent economic and geopolitical crisis episodes, by developing consumer and producer distress indices that signal the build-up of upside and downside price risk, and by conducting a risk scenario analysis for 2024.

The Effect of Bank Organizational Risk-management on the Price of Non-deposit Debt

2024
Abstract
We test whether organizational risk management matters to bondholders of U.S. bank holding companies (BHCs), and find that debt financing costs increase when the BHC has lower-quality risk management. Consistent with bailouts giving rise to moral hazard among bank creditors, we find that bondholders put less emphasis on risk management in large institutions for which bailouts are expected ex-ante. BHCs that maintained strong risk management before the financial crisis had lower debt costs during and after the crisis, compared to other banks. Overall, quality risk management can curtail risk exposures at BHCs and result in lower debt costs.

Climate Stress Tests, Bank Lending, and the Transition to the Carbon-neutral Economy

No. 9,
2024
Abstract
We ask if bank supervisors’ efforts to combat climate change affect banks’ lending and their borrowers’ transition to the carbon-neutral economy. Combining information from the French supervisory agency’s climate pilot exercise with borrowers’ emission data, we first show that banks that participate in the exercise increase lending to high-carbon emitters but simultaneously charge higher interest rates. Second, participating banks collect new information about climate risks, and boost lending for green purposes. Third, receiving credit from a participating bank facilitates borrowers’ efforts to improve environmental performance. Our findings establish a hitherto undocumented link between banking supervision and the transition to net-zero.
