This paper explores the intersection of climate change policies with banking supervisory law. Statutory mandates define banking supervisory agencies’ objectives, functions and powers. Policies that aim to address climate change risks appear fully germane to banking supervisors’ main objective of safety and soundness. As such, banking supervisory agencies have a duty to address climate risks in light of their mandate. A mandate that is not anchored on safety and soundness in light of best practice would blur the accountability of banking supervisory agencies and undermine their legitimacy also with respect to climate. While legal changes can help provide greater legal certaintly, particularly given the long-term perspective of climate change, bank supervisory agencies can take action without fundamental reforms of their legal framework. Accordingly, they have set expectations or requirements for banks to incorporate climate into their strategy and business model, risk management, and governance. A combination of legal instruments—based on soft law and hard law—helps to achieve this objective. Notwithstanding implementation challenges, taxonomies and disclosures remain important tools, and banking supervisors should assess their role in the development of such tools in light of their mandate. The key responsibility to address climate risks rests on banks, and corporate governance frameworks could assist.

This paper studies the impact of U.S. immigration barriers on global knowledge production. We present four key findings. First, among Nobel Prize winners and Fields Medalists, migrants to the U.S. play a central role in the global knowledge network—representing 20-33% of the frontier knowledge producers. Second, using novel survey data and hand-curated life-histories of International Math Olympiad (IMO) medalists, we show that migrants to the U.S. are up to six times more productive than migrants to other countries—even after accounting for talent during one’s teenage years. Third, financing costs are a key factor preventing foreign talent from migrating abroad to pursue their dream careers, particularly for talent from developing countries. Fourth, certain ‘push’ incentives that reduce immigration barriers—by addressing financing constraints for top foreign talent—could increase the global scientific output of future cohorts by 42 percent. We concludeby discussing policy options for the U.S. and the global scientific community.
