- Abstract
- We analyze jointly optimal carbon pricing and leverage regulation in a model with financial constraints and endogenous climate-related transition and physical risks. The socially optimal emissions tax is below the Pigouvian benchmark (equal to the direct social cost of emissions) when emissions taxes amplify financial constraints, or above this benchmark if physical climate risks have a substantial impact on collateral values. Additionally introducing leverage regulation can be welfare-improving only if tax rebates are not fully pledgeable. A cap-and-trade system or abatement subsidies may dominate carbon taxes because they can be designed to have a less adverse effect on financial constraints.

- Abstract
- The post-crisis regulatory framework introduced multiple requirements on banks’ capital and liquidity positions, sparking a discussion among policymakers and academics on how the various requirements interact with one another. This article contributes to the discussion on the interaction of different regulatory metrics by empirically examining the interaction between the liquidity coverage ratio (LCR) and the net stable funding ratio (NSFR) for banks in the euro area. The findings suggest that the two liquidity requirements are complementary and constrain different types of banks in different ways, similarly to the risk-based and leverage ratio requirements in the capital framework. This dispels claims that the LCR and the NSFR are redundant and underlines the need for a faithful and consistent implementation of both measures (and the entire Basel III package more broadly) across all major jurisdictions, to maintain a level playing field at the global level and to ensure that the post-crisis regulatory framework delivers on its objectives.
