Abstract
This paper compares the out-of-sample predictive performance of different early warning models for systemic banking crises using a sample of advanced economies covering the past 45 years. We compare a benchmark logit approach to several machine learning approaches recently proposed in the literature. We find that while machine learning methods often attain a very high in-sample fit, they are outperformed by the logit approach in recursive out-of-sample evaluations. This result is robust to the choice of performance metric, crisis definition, preference parameter, and sample length, as well as to using different sets of variables and data transformations. Thus, our paper suggests that further enhancements to machine learning early warning models are needed before they are able to offer a substantial value-added for predicting systemic banking crises. Conventional logit models appear to use the available information already fairly efficiently, and would for instance have been able to predict the 2007/2008 financial crisis out-of-sample for many countries. In line with economic intuition, these models identify credit expansions, asset price booms and external imbalances as key predictors of systemic banking crises.

Structural Stability of the Research & Development Sector in European Economies Despite the Economic Crisis

No. 5,

Abstract
When an external shock such as the economic crisis in 2008/2009 occurs, the interconnectedness of sectors can be affected. This paper investigates whether the R&D sector experienced changes in its sectoral integration through the recession. Based on an input-output analysis, it can be shown that the linkages of the R&D sector with other sectors remain stable. In some countries, the inter-sectoral integration becomes even stronger. Policy makers can be encouraged to use public R&D spending as a means of fiscal policy against an economic crisis.

Deleveraging and Consumer Credit Supply in the Wake of the 2008–09 Financial Crisis

Abstract
We explore the sources of the decline in household nonmortgage debt following the collapse of the housing market in 2006. First, we use data from the Federal Reserve Board's Senior Loan Officer Opinion Survey to document that, post-2006, banks tightened consumer lending standards more in counties that experienced a more pronounced house price decline (the pre-2006 "boom" counties). We then use the idea that renters did not experience an adverse wealth or collateral shock when the housing market collapsed to identify a general consumer credit supply shock. Our evidence suggests that a tightening of the supply of non-mortgage credit that was independent of the direct effects of lower housing collateral values played an important role in households' non-mortgage debt reduction. Renters decreased their non-mortgage debt more in boom counties than in non-boom counties, but homeowners did not. We argue that this wedge between renters and homeowners can only have arisen from a general tightening of banks' consumer lending stance. Using an IV approach, we trace this effect back to a reduction in bank capital of banks in boom counties.

Do Conventional Monetary Policy Instruments Matter in Unconventional Times?
Manuel Buchholz, Kirsten Schmidt, Lena Tonzer
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 well-capitalized 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.

Kommentar: Die Krise von 2008/2009 ist noch nicht vorbei

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?

Langfristige Konsequenzen der Finanzkrise 2008/2009: Nachsichtige Regulierung schadet, flexible Löhne helfen

No. 2,
2019
Abstract
Die globale Bankenkrise der Jahre 2008/2009 hatte weltweit signifikant negative Auswirkungen auf die Realwirtschaft, und in vielen Ländern fiel die folgende wirtschaftliche Erholung deutlich langsamer aus als in vorherigen Rezessionen. In den Monaten nach der Insolvenz der amerikanischen Investmentbank Lehman Brothers reduzierten Banken ihre Kreditvergabe an Unternehmen, was zu einem Anstieg der Arbeitslosigkeit, einem Rückgang an Investitionen und einer Verringerung der Produktivität führte. Während diese kurzfristigen Effekte in der bisherigen Forschung gut dokumentiert sind, sind die langfristigen Auswirkungen von Bankenkrisen bisher weit weniger gut verstanden. Zwei aktuelle Studien unter IWH-Beteiligung zeigen, dass Bankenkrisen generell negative langfristige Effekte auf das Wachstum von Firmen haben, dass die Rettung von schwachen Banken während der Krise mit Produktivitätsverlusten in späteren Jahren einhergeht, und dass diese negativen langfristigen Effekte durch die Existenz inflexibler Löhne verstärkt 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”.

Banks' Funding Stress, Lending Supply and Consumption Expenditure
H. Evren Damar, Reint E. Gropp, Adi Mordel
Abstract
We employ a unique identification strategy linking survey data on household consumption expenditure to bank-level data to estimate the effects of bank funding stress on consumer credit and consumption expenditures. We show that households whose banks were more exposed to funding shocks report lower levels of nonmortgage liabilities. This, however, only translates into lower levels of consumption for low income households. Hence, adverse credit supply shocks are associated with significant heterogeneous effects.

On the Empirics of Reserve Requirements and Economic Growth

2019
Abstract
Reserve requirements, as a tool of macroprudential policy, have been increasingly employed since the outbreak of the great financial crisis. We conduct an analysis of the effect of reserve requirements in tranquil and crisis times on long-run growth rates of GDP per capita and credit (%GDP) making use of Bayesian model averaging methods. Regulation has on average a negative effect on GDP in tranquil times, which is only partly offset by a positive (but not robust effect) in crisis times. Credit over GDP is positively affected by higher requirements in the longer run.

Price-cost Margin and Bargaining Power in the European Union

IWH-CompNet Discussion Papers,
No. 4,
2019
Abstract
Using firm-level data between 2004 and 2012 for eleven countries of the European Union (EU), we document the size of product and labour market imperfections within narrowly defined sectors including services which are virtually undocumented. Our findings suggest that perfect competition in both product and labour markets is widely rejected. Levels of the price-cost margin and union bargaining power tend to be higher in some service sectors depicting however substantial heterogeneity. Dispersion within sector and across countries tends to be higher in some services sectors assuming a less tradable nature which suggests that the Single Market integration is partial particularly relaxing the assumption of perfect competition in the labour market. We report also figures for the aggregate economy and show that Eastern countries tend to depict lower product and labour market imperfections compared to other countries in the EU. Also, we provide evidence in favour of a very limited adjustment of both product and labour market imperfections following the international and financial crisis.
