Financial Constraints and Emission Intensity,  Single author (Draft available upon request)

"This paper examines how tighter financial constraints affect firms' emission intensity through an internal capital market lens. Winner-picking incentives predict cuts for marginal projects. When marginal projects are clean this increases emission intensity. First, I show that dirtier subsidiaries are more profitable for European firms in emission-intensive sectors. Then, exploiting the EBA Capital Exercise in 2011 as a shock to bank credit in a difference-in-difference (DiD) setting, I show that treated firms' clean subsidiaries shrink. However, what if funding access is linked to environmental performance? Firms may shift to cleaner projects to relax financial constraints reducing emission intensity (constraint-minimization mechanism). A theoretical framework models the trade-off between winner-picking and constraint-minimization. Finally, exploiting banks’ sustainable commitments in a staggered DiD setting I find that firms engage in constraint-minimization when credit constraints are related to environmental performance. Thus, the impact of financial constraints on emission intensity depends on firms' internal funding allocation and the nature of the constraint."

ECB Working Paper N.2670 (2022), Latest version available upon request. 

"We analyze how firms' climate change-related regulatory risks affect banks' lending. Exploiting the Paris Agreement in a difference-in-differences setting, we find that effects depend on how borrowers will be affected by regulation as well as the stringency of the existing regulatory environment where firms are located. Firms that benefit from regulation receive more credit only if located in more stringent regulatory environments. Conversely, firms hurt by regulation receive more credit if located in less stringent environments or if linked to banks with a portfolio tilted toward lending to negatively impacted firms. "

"The establishment of the European Banking Union constitutes a major change in the regulatory framework of the banking system. Main parts are implemented via directives that show staggered transposition timing across EU member states. Based on the newly compiled Banking Union Directives Database, we assess how banks' funding costs responded to the Capital Requirements Directive IV (CRD IV). Our findings show an upward trend in funding costs which is driven by an increase in cost of equity and partially offset by a decline in cost of debt. The diverging trends are most present in countries with an ex-ante lower regulatory capital stringency, which is in line with banks' short-run adjustment needs but longer-run benefits from increased financial stability.

Completing the European Banking Union: Capital cost consequences for credit providers and corporate borrowers, with Michael Koetter, Thomas Krause and Lena Tonzer, European Economic Review, Volume 148, September 2022, 104229

"The bank recovery and resolution directive (BRRD) regulates the bail-in hierarchy to resolve distressed banks in the European Union (EU). Using the staggered BRRD implementation across 15 member states, we identify banks’ capital cost responses and subsequent pass-through to borrowers towards surprise elements due to national transposition details. Average bank capital costs increase heterogeneously across countries with strongest funding cost hikes observed for banks located in GIIPS and non-EMU countries. Only banks in core E(M)U countries that exhibit higher funding costs increase credit spreads for corporate borrowers and contract credit supply. Tighter credit conditions are only passed on to more levered and less profitable firms. On balance, the national implementation of BRRD appears to have strengthened financial system resilience without a pervasive hike in borrowing costs."
