Abstract
We investigate whether ratings-based capital regulation has affected the finance-growth nexus via a foreign credit channel. Using quarterly data on short to medium term real GDP growth and cross-border bank lending flows from G-10 countries to 67 recipient countries, we find that since the implementation of Basel 2 capital rules, risk weight reductions mapped to sovereign credit rating upgrades have stimulated short-term economic growth in investment grade recipients but hampered growth in non-investment grade recipients. The impact of these rating upgrades is strongest in the first year and then reverses from the third year and onwards. On the other hand, there is a consistent and lasting negative impact of risk weight increases due to rating downgrades across all recipient countries. The adverse effects of ratings-based capital regulation on foreign bank credit supply and economic growth are compounded in countries with more corruption and less competitive banking sectors and are attenuated with greater political stability.

Abstract
Die Corona-bedingte Wirtschaftskrise könnte den deutschen Bankensektor massiv in Mitleidenschaft ziehen, wenn die nationale und europäische Aufsicht nicht in den nächsten Monaten gegensteuert. Das ist die Aussage einer IWH-Studie, in der wir die Jahresabschlüsse von mehr als einer halben Million deutscher Unternehmen mit den Bilanzdaten von über 1 000 hiesigen Banken verknüpft haben. Die Stichprobe umfasst rund 90% der Bilanzsumme aller Banken und schließt alle großen systemrelevanten Geldhäuser mit ein. Wir benutzen dabei sektorspezifische Prognosen für die wirtschaftliche Entwicklung: Wir beziehen also die Tatsache mit ein, dass die Tourismusbranche besonders und die Baubranche relativ wenig von der Krise betroffen ist. Wir simulieren mehrere Szenarien: eines mit einer schnellen Erholung (V-förmig), eines mit einer relativ langsamen Erholung (U) und ein Szenario, in dem die Krise noch eine längere Zeit anhält (L).

Transmitting Fiscal Covid-19 Counterstrikes Effectively: Mind the Banks!

No. 2,
2020
Abstract
The German government launched an unprecedented range of support programmes to mitigate the economic fallout from the Covid-19 pandemic for employees, self-employed, and firms. Fiscal transfers and guarantees amount to approximately €1.2 billion by now and are supplemented by similarly impressive measures taken at the European level. We argue in this note that the pandemic poses, however, also important challenges to financial stability in general and bank resilience in particular. A stable banking system is, in turn, crucial to ensure that support measures are transmitted to the real economy and that credit markets function seamlessly. Our analysis shows that banks are exposed rather differently to deteriorated business outlooks due to marked differences in their lending specialisation to different economic sectors. Moreover, a number of the banks that were hit hardest by bleak growth prospects of their borrowers were already relatively thinly capitalised at the outset of the pandemic. This coincidence can impair the ability and willingness of selected banks to continue lending to their mostly small and medium sized entrepreneurial customers. Therefore, ensuring financial stability is an important pre-requisite to also ensure the effectiveness of fiscal support measures. We estimate that contracting business prospects during the first quarter of 2020 could lead to an additional volume of non-performing loans (NPL) among the 40 most stressed banks ‒ mostly small, regional relationship lenders ‒ on the order of around €200 million. Given an initial stock of NPL of €650 million, this estimate thus suggests a potential level of NPL at year-end of €1.45 billion for this fairly small group of banks already. We further show that 17 regional banking markets are particularly exposed to an undesirable coincidence of starkly deteriorating borrower prospects and weakly capitalised local banks. Since these regions are home to around 6.8% of total employment in Germany, we argue that ensuring financial stability in the form of healthy bank balance sheets should be an important element of the policy strategy to contain the adverse real economic effects of the pandemic.

Kommentar: Die Krise von 2008/2009 ist noch nicht vorbei
Reint E. Gropp
Wirtschaft im Wandel,
No. 2,
2019
Abstract
Kurzfristig war die Finanzkrise, ursprünglich ausgelöst durch exzessive Vergabe von Hypotheken an weniger kreditwürdige Haushalte, verbunden mit der weitverbreiteten Verbriefung dieser Hypotheken, mit schweren realwirtschaftlichen Konsequenzen verbunden. Die Volkswirtschaften aller Industrieländer schrumpften stark, die Arbeitslosigkeit stieg kräftig an. Firmen waren nicht in der Lage, neue Investitionen zu finanzieren, da es für Banken in vielen Ländern nicht möglich war, Kredite zu vergeben. Gleichzeitig führten die Rettungsaktionen der Regierungen zu einer starken Erhöhung der Schuldenstände und zu einer Nullzinspolitik, verbunden mit Anleihekäufen, der wichtigsten Zentralbanken.
Wo stehen wir heute, über zehn Jahre nach der Pleite von Lehman, die symbolisch noch immer eng mit der Krise verbunden ist? Und gibt es langfristige Auswirkungen auf die Wirtschaft – Auswirkungen, die wir noch heute spüren und möglicherweise noch viele Jahre spüren werden?

Study: How financial crises lower life satisfaction and how to prevent this
Financial crises not only result in severe disruptions to the economic system, they also affect people’s life satisfaction. A new study by Martin Luther University Halle-Wittenberg (MLU) and the Halle Institute for Economic Research (IWH) shows that weaker members of society are more affected by increased uncertainty during crisis times, even if they may not be speculating on the stock market themselves. This could potentially also lower their propensity to consume, thereby intensifying the impact of a financial crisis. The study was recently published in “The B.E. Journal of Economic Analysis & Policy”.

Bank profitability increases after eliminating consolidation barriers
When two banks merge because political consolidation barriers are abolished, the combined entity is considerably more profitable and useful to the real economy. This is the headline result of an analysis of compulsory savings banks mergers carried out by the Halle Institute for Economic Research (IWH). The study yields important insights for the German and the European banking market.

What Drives Banks‘ Geographic Expansion? The Role of Locally Non-diversifiable Risk
Reint E. Gropp, Felix Noth, Ulrich Schüwer
IWH Discussion Papers,
No. 6,
2019
Abstract
We show that banks that are facing relatively high locally non-diversifiable risks in their home region expand more across states than banks that do not face such risks following branching deregulation in the 1990s and 2000s. These banks with high locally non-diversifiable risks also benefit relatively more from deregulation in terms of higher bank stability. Further, these banks expand more into counties where risks are relatively high and positively correlated with risks in their home region, suggesting that they do not only diversify but also build on their expertise in local risks when they expand into new regions.

What Type of Finance Matters for Growth? Bayesian Model Averaging Evidence
Iftekhar Hasan, Roman Horvath, Jan Mares
World Bank Economic Review,
No. 2,
2018
Abstract
We examine the effect of finance on long-term economic growth using Bayesian model averaging to address model uncertainty in cross-country growth regressions. The literature largely focuses on financial indicators that assess the financial depth of banks and stock markets. We examine these indicators jointly with newly developed indicators that assess the stability and efficiency of financial markets. Once we subject the finance-growth regressions to model uncertainty, our results suggest that commonly used indicators of financial development are not robustly related to long-term growth. However, the findings from our global sample indicate that one newly developed indicator—the efficiency of financial intermediaries—is robustly related to long-term growth.

Effectiveness and (In)Efficiencies of Compensation Regulation: Evidence from the EU Banker Bonus Cap
Stefano Colonnello, Michael Koetter, Konstantin Wagner
Abstract
We investigate the (unintended) effects of bank executive compensation regulation. Capping the share of variable compensation spurred average turnover rates driven by CEOs at poorly performing banks. Other than that, banks‘ responses to raise fixed compensation sufficed to retain the vast majority of non-CEO executives and those at well performing banks. We fail to find evidence that banks with executives that are more affected by the bonus cap became less risky. In fact, numerous results indicate an increase of risk, even in its systemic dimension according to selected measures. The return component of bank performance appears to be unaffected by the bonus cap. Risk hikes are consistent with an insurance effect associated with raised the increase in fixed compensation of executives. The ability of the policy to enhance financial stability is therefore doubtful.
