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

Do Affiliated Bankers on Board Enhance Corporate Social Responsibility? US Evidence

Iftekhar Hasan Hui Li Haizhi Wang Yun Zhu

in: Sustainability, Nr. 6, 2021

Abstract

In this study, we examine whether and to what extent affiliated bankers on board may affect firms’ corporate social performance. Using a propensity score-matched sample from 2002 to 2016, we find that board directors from affiliated banks exert significantly positive influence on firms’ corporate social performance. Furthermore, board of directors from affiliated banks are negatively associated with firm investments in corporate social responsibility (CSR) activities when firms experience financial distress. Finally, we find that the effect of affiliated bankers on board on firms’ CSR performance depends on the affiliated banks’ CSR orientation, as affiliated banker directors from banks with higher CSR orientation have a stronger influence on firms’ investments in CSR activities. The results suggest that improving firm’s CSR performance is consistent with the affiliated banks’ interests.

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.

How Do EU Banks’ Funding Costs Respond to the CRD IV? An Assessment Based on the Banking Union Directives Database

Thomas Krause Eleonora Sfrappini Lena Tonzer Cristina Zgherea

in: IWH Discussion Papers, Nr. 12, 2024

Abstract

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.

The Effect of Firm Subsidies on Credit Markets

Aleksandr Kazakov Michael Koetter Mirko Titze Lena Tonzer

in: IWH Discussion Papers, Nr. 24, 2022

Abstract

<p>We use project-level information for the largest regional economic development program in German history to study how government subsidies to firms affect credit markets. We identify credit market responses by considering both, bank lending and firm borrowing during 1998-2019. We find that subsidies lead to larger lending volumes without crowding out credit to non-subsidized firms. Banks that are more exposed to subsidized firms exhibit moderately higher credit risk though. Firm subsidies support lending especially when credit constraints are elevated during the years of the financial crisis.</p>

Climate Change-Related Regulatory Risks and Bank Lending

Isabella Müller Eleonora Sfrappini

in: ECB Working Paper, Nr. 2670, 2022

Abstract

We identify the effect of climate change-related regulatory risks on credit real-location. Our evidence suggests that effects depend borrower's region. Following an increase in salience of regulatory risks, banks reallocate credit to US firms that could be negatively impacted by regulatory interventions. Conversely, in Europe, banks lend more to firms that could benefit from environmental regulation. The effect is moderated by banks' own loan portfolio composition. Banks with a portfolio tilted towards firms that could be negatively a affected by environmental policies increasingly support these firms. Overall, our results indicate that financial implications of regulation associated with climate change appear to be the main drivers of banks' behavior.

Explaining Regional Disparities in Housing Prices Across German Districts

Lars Brausewetter Stephan L. Thomsen Johannes Trunzer

in: IWH Discussion Papers, Nr. 13, 2022

Abstract

Over the last decade, German housing prices have increased unprecedentedly. Drawing on quality-adjusted housing price data at the district level, we document large and increasing regional disparities: Growth rates were higher in 1) the largest seven cities, 2) districts located in the south, and 3) districts with higher initial price levels. Indications of price bubbles are concentrated in the largest cities and in the purchasing market. Prices seem to be driven by the demand side: Increasing population density, higher shares of academically educated employees and increasing purchasing power explain our findings, while supply remained relatively constrained in the short term.

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.
