Cultural Norms and Corporate Fraud: Evidence from the Volkswagen Scandal

Iftekhar Hasan Felix Noth Lena Tonzer

in: Journal of Corporate Finance, October 2023

Abstract

We examine a corporate governance role of local culture via its impact on consumer behavior following corporate scandals. Our proxy for culture is the presence of local Protestantism. Exploiting the unexpected nature of the Volkswagen (VW) diesel scandal in September 2015, we show that new registrations of VW cars decline significantly in German counties with a Protestant majority following the VW scandal. Further survey evidence shows that, compared to Catholics, Protestants respond significantly more negatively to fraud but not to environmental issues. Our findings suggest that the enforcement culture in Protestantism facilitates penalizing corporate fraud.

Financial Linkages and Sectoral Business Cycle Synchronization: Evidence from Europe

Hannes Böhm Julia Schaumburg Lena Tonzer

in: IMF Economic Review, December 2022

Abstract

We analyze whether financial integration leads to converging or diverging business cycles using a dynamic spatial model. Our model allows for contemporaneous spillovers of shocks to GDP growth between countries that are financially integrated and delivers a scalar measure of the spillover intensity at each point in time. For a financial network of ten European countries from 1996 to 2017, we find that the spillover effects are positive on average and much larger during periods of financial stress, pointing towards stronger business cycle synchronization. Dismantling GDP growth into value added growth of ten major industries, we observe that spillover intensities vary significantly. The findings are robust to a variety of alternative model specifications.

Completing the European Banking Union: Capital Cost Consequences for Credit Providers and Corporate Borrowers

Michael Koetter Thomas Krause Eleonora Sfrappini Lena Tonzer

in: European Economic Review, September 2022

Abstract

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.

Firm Subsidies, Financial Intermediation, and Bank Stability

Aleksandr Kazakov Michael Koetter Mirko Titze Lena Tonzer

in: IWH Discussion Papers, Nr. 24, 2022

Abstract

We use granular project-level information for the largest regional economic development program in German history to study whether government subsidies to firms affect the quantity and quality of bank lending. We combine the universe of recipient firms under the Improvement of Regional Economic Structures program (GRW) with their local banks during 1998-2019. The modalities of GRW subsidies to firms are determined at the EU level. Therefore, we use it to identify bank outcomes. Banks with relationships to more subsidized firms exhibit higher lending volumes without any significant differences in bank stability. Subsidized firms, in turn, borrow more indicating that banks facilitate regional economic development policies.

A Note on the Use of Syndicated Loan Data

Isabella Müller Felix Noth Lena Tonzer

in: IWH Discussion Papers, Nr. 17, 2022

Abstract

Syndicated loan data provided by DealScan has become an essential input in banking research over recent years. This data is rich enough to answer urging questions on bank lending, e.g., in the presence of financial shocks or climate change. However, many data options raise the question of how to choose the estimation sample. We employ a standard regression framework analyzing bank lending during the financial crisis to study how conventional but varying usages of DealScan affect the estimates. The key finding is that the direction of coefficients remains relatively robust. However, statistical significance seems to depend on the data and sampling choice.

Uncertainty, Financial Crises, and Subjective Well-being

Lena Tonzer

in: IWH Discussion Papers, Nr. 2, 2017

Abstract

This paper focuses on the effect of uncertainty as reflected by financial market variables on subjective well-being. The analysis is based on Eurobarometer surveys, covering 20 countries over the period from 2000 to 2013. Individuals report lower levels of life satisfaction in times of higher uncertainty approximated by stock market volatility. This effect is heterogeneous across respondents: The probability of being unsatisfied is higher for respondents who are older, less educated, and live in one of the GIIPS countries of the euro area. Furthermore, higher uncertainty in combination with a financial crisis increases the probability of reporting low values of life satisfaction.
