Regulierung internationaler Finanzmärkte und Banken

Diese Forschungsgruppe analysiert Ursachen und Konsequenzen von internationalen Aktivitäten von Banken sowie den regulatorischen Rahmen, innerhalb dessen globale Banken operieren.

International aktive Banken können eine effiziente internationale Kapitalallokation vereinfachen und zur internationalen Risikoteilung beitragen. Allerdings können sie auch Instabilitäten generieren und zu einer Übertragung von Schocks über nationale Grenzen hinaus beitragen. Dies ist einer der Gründe für die aktuelle Re-Regulierung des internationalen Bankensystems.

Die Forschungsgruppe trägt auf drei verschiedenen Wegen zur Literatur bei. Erstens analysiert die Gruppe empirisch, warum internationale Banken global aktiv sind und wie Schocks im Finanzsystem übertragen werden. Zweitens untersucht die Gruppe das Entstehen von systemischen Risiken und Ungleichgewichten im integrierten Bankenmarkt und die sich daraus ergebenden Konsequenzen für die Realwirtschaft. Drittens werden die Auswirkungen von Änderungen bezüglich der Bankenaufsicht und Bankenregulierung analysiert, mit einem besonderen Fokus auf dem europäischen Integrationsprozess

Who Benefits from Mandatory CSR? Evidence from the Indian Companies Act 2013

Jitendra Aswani N. K. Chidambaran Iftekhar Hasan

in: Emerging Markets Review, March 2021

Abstract

We examine the value impact of mandatory Corporate Social Responsibility (CSR) spending required by the Indian Companies Act of 2013 for large and profitable Indian firms. We find that the external mandate is value decreasing, even after controlling for prior voluntary CSR activity by firms affected by the mandate. We also find that there is systematic crosssectional variation across firms. Firms that are profitable and firms in the Fast Moving Consumer Goods sector that voluntarily engaged in CSR, benefit from CSR. Industrial firms and firms with high capital expenditures are negatively impacted by the mandate. We conclude that a one-size-fits-all approach to CSR is sub-optimal and value decreasing.

Lending Effects of the ECB’s Asset Purchases

Michael Koetter

in: Journal of Monetary Economics, December 2020

Abstract

Between 2010 and 2012, the European Central Bank absorbed €218 billion worth of government securities from five EMU countries under the Securities Markets Programme (SMP). Detailed security holdings data at the bank level affirms an effective lending stimulus due to the SMP. Exposed banks contract household lending, but increase commercial lending substantially. Holding non-SMP securities from stressed EMU countries amplifies the commercial lending response. The SMP also improved liquidity buffers and profitability without compromising credit quality.

The Impact of Social Capital on Economic Attitudes and Outcomes

Iftekhar Hasan Qing He Haitian Lu

in: Journal of International Money and Finance, November 2020

Abstract

This article traces the extant literature on the impact of social capital on economic attitudes and outcomes. Special attention is paid to clarify conceptual ambiguities, measurement techniques, channels of influence, and identification strategies. Insights derived from the literature are then used to analyze the marketplace lending industry in China, where the size of the peer-to-peer (P2P) lending market is larger than that of the rest of the world combined. Ironically, approximately two-thirds of these online P2P lending platforms have failed. Empirical evidence from the monthly operating data of 735 lending platforms and transaction level data from one prominent platform (Renrendai) shows that platforms in provinces with high social capital have low risk of failure, and borrowers in provinces with high social capital can borrow at low interest rate and are less likely to default. We also provide observations to guide future economic research on social capital.

Finance and Wealth Inequality

Iftekhar Hasan Roman Horvath Jan Mares

in: Journal of International Money and Finance, November 2020

Abstract

Using a global sample, this paper investigates the determinants of wealth inequality capturing various economic, financial, political, institutional, and geographical indicators. Using instrumental variable Bayesian model averaging, it reveals that only a handful of indicators robustly matters and finance plays a key role. It reports that while financial depth increases wealth inequality, efficiency and access to finance reduce inequality. In addition, redistribution and education are associated with lower inequality whereas wars and openness to international trade contribute to greater wealth inequality.

Do Conventional Monetary Policy Instruments Matter in Unconventional Times?

Manuel Buchholz Kirsten Schmidt Lena Tonzer

in: Journal of Banking and Finance, Nr. 105874, September 2020

Abstract

This paper investigates how declines in the deposit facility rate set by the ECB affect euro area banks’ incentives to hold reserves at the central bank. We find that, in the face of lower deposit rates, banks with a more interest-sensitive business model are more likely to reduce reserve holdings and allocate freed-up liquidity to loans. The result is driven by banks in the non-GIIPS countries of the euro area. This reveals that conventional monetary policy instruments have limited effects in restoring monetary policy transmission during times of crisis.

Stress-ridden Finance and Growth Losses: Does Financial Development Break the Link?

Serafín Martínez-Jaramillo Ricardo Montañez-Enríquez Matias Ossandon Busch Manuel Ramos-Francia Anahí Rodríguez-Martínez José Manuel Sánchez-Martínez

in: IWH Discussion Papers, Nr. 3, 2022

Abstract

Does financial development shield countries from the pass-through of financial shocks to real outcomes? We evaluate this question by characterising the probability density of expected GDP growth conditional on financial stability indicators in a panel of 28 countries. Our robust results unveil a non-linear nexus between financial stability and expected GDP growth, depending on countries’ degree of financial development. While both domestic and global financial factors affect expected growth, the effect of global factors is moderated by financial development. This result highlights a previously unexplored channel trough which financial development can break the link between financial (in)stability and GDP growth.

Firm Subsidies, Financial Intermediation, and Bank Risk

Aleksandr Kazakov Michael Koetter Mirko Titze Lena Tonzer

in: IWH Discussion Papers, Nr. 2, 2022

Abstract

We study whether government subsidies can stimulate bank funding of marginal investment projects and the associated effect on financial stability. We do so by exploiting granular project-level information for the largest regional economic development programme in Germany since 1997: the Improvement of Regional Economic Structures programme (GRW). By combining the universe of subsidised firms to virtually all German local banks over the period 1998-2019, we test whether this large-scale transfer programme destabilised regional credit markets. Because GRW subsidies to firms are destabilised at the EU level, we can use it as an exogenous shock to identify bank responses. On average, firm subsidies do not affect bank lending, but reduce banks’ distance to default. Average effects conflate important bank-level heterogeneity though. Conditional on various bank traits, we show that well capitalised banks with more industry experience expand lending when being exposed to subsidised firms without exhibiting more risky financial profiles. Our results thus indicate that stable banks can act as an important facilitator of regional economic development policies. Against the backdrop of pervasive transfer payments to mitigate Covid-19 losses and in light of far-reaching transformation policies required to green the economy, our study bears important implications as to whether and which banks to incorporate into the design of transfer Programmes.

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

Michael Koetter Thomas Krause Eleonora Sfrappini Lena Tonzer

in: IWH Discussion Papers, Nr. 4, 2021

Abstract

The bank recovery and resolution directive (BRRD) regulates the bail-in hierarchy to resolve distressed banks without burdening tax payers. We exploit the staggered implementation of the BRRD across 15 European Union (EU) member states to identify banks’ capital cost and capital structure responses. In a first stage, we show that average capital costs of banks increased. WACC hikes are lowest in the core countries of the European Monetary Union (EMU) compared to formerly stressed EMU and non-EMU countries. This pattern is driven by changes in the relative WACC weight of equity in response to the BRRD, which indicates enhanced financial system resilience. In a second stage, we document asymmetric transmission patterns of banks’ capital cost changes on to corporates’ borrowing terms. Only EMU banks located in core countries that exhibit higher WACC are those that also increase firms’ borrowing cost and contract credit supply. Hence, the BRRD had unintended consequences for selected segments of the real economy.

The Cleansing Effect of Banking Crises

Reint E. Gropp Steven Ongena Jörg Rocholl Vahid Saadi

in: IWH Discussion Papers, Nr. 12, 2020

Abstract

We assess the cleansing effects of the recent banking crisis. In U.S. regions with higher levels of supervisory forbearance on distressed banks during the crisis, there is less restructuring in the real sector and the banking sector remains less healthy for several years after the crisis. Regions with less supervisory forbearance experience higher productivity growth after the crisis with more firm entries, job creation, and employment, wages, patents, and output growth. Supervisory forbearance is greater for state-chartered banks and in regions with weaker banking competition and more independent banks, while recapitalisation of distressed banks through TARP does not facilitate cleansing.
