Abstract
Recurring financial instabilities have led policymakers to rely on early-warning models to signal financial vulnerabilities. These models rely on ex-post optimization of signaling thresholds on crisis probabilities accounting for preferences between forecast errors, but come with the crucial drawback of unstable thresholds in recursive estimations. We propose two alternatives for threshold setting with similar or better out-of-sample performance: (i) including preferences in the estimation itself and (ii) setting thresholds ex-ante according to preferences only. Given probabilistic model output, it is intuitive that a decision rule is independent of the data or model specification, as thresholds on probabilities represent a willingness to issue a false alarm vis-à-vis missing a crisis. We provide real-world and simulation evidence that this simplification results in stable thresholds, while keeping or improving on out-of-sample performance. Our solution is not restricted to binary-choice models, but directly transferable to the signaling approach and all probabilistic early-warning models.

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).

Decentralisation of Collective Bargaining: A Path to Productivity?
Daniele Aglio, Filippo di Mauro
IWH-CompNet Discussion Papers,
No. 3,
2020
Abstract
Productivity developments have been rather divergent across EU countries and particularly between Central Eastern Europe (CEE) and elsewhere in the continent (non-CEE). How is such phenomenon related to wage bargaining institutions? Starting from the Great Financial Crisis (GFC) shock, we analyse whether the specific set-up of wage bargaining prevailing in non-CEE may have helped their respective firms to sustain productivity in the aftermath of the crisis. To tackle the issue, we merge the CompNet dataset – of firm-level based productivity indicators – with the Wage Dynamics Network (WDN) survey on wage bargaining institutions. We show that there is a substantial difference in the institutional set-up between the two above groups of countries. First, in CEE countries the bulk of the wage bargaining (some 60%) takes place outside collective bargaining schemes. Second, when a collective bargaining system is adopted in CEE countries, it is prevalently in the form of firm-level bargaining (i. e. the strongest form of decentralisation), while in non-CEE countries is mostly subject to multi-level bargaining (i. e. an intermediate regime, only moderately decentralised). On productivity impacts, we show that firms’ TFP in the non-CEE region appears to have benefitted from the chosen form of decentralisation, while no such effects are detectable in CEE countries. On the channels of transmission, we show that decentralisation in non-CEE countries is also negatively correlated with dismissals and with unit labour costs, suggesting that such collective bargaining structure may have helped to better match workers with firms’ needs.

Private Equity and Portfolio Companies: Lessons From the Global Financial Crisis

Journal of Applied Corporate Finance,
No. 3,
2020
Abstract
Critics of private equity have warned that the high leverage often used in PE-backed companies could contribute to the fragility of the financial system during economic crises. The proliferation of poorly structured transactions during booms could increase the vulnerability of the economy to downturns. The alternative hypothesis is that PE, with its operating capabilities, expertise in financial restructuring, and massive capital raised but not invested ("dry powder"), could increase the resilience of PE-backed companies. In their study of PE-backed buyouts in the U.K. - which requires and thereby makes accessible more information about private companies than, say, in the U.S. - the authors report finding that, during the 2008 global financial crisis, PE-backed companies decreased their overall investments significantly less than comparable, non-PE firms. Moreover, such PE-backed firms also experienced greater equity and debt inflows, higher asset growth, and increased market share. These effects were especially notable among smaller, riskier PE-backed firms with less access to capital, and also for those firms backed by PE firms with more dry powder at the crisis onset. In a survey of the partners and staff of some 750 PE firms, the authors also present compelling evidence that PEs firms play active financial and operating roles in preserving or restoring the profitability and value of their portfolio companies.

Transformation und Finanzmärkte: Die Rolle evidenzbasierter Politik
Claudia M. Buch
Beitrag in IWH-Sammelwerk,
Festschrift für Gerhard Heimpold, IWH
2020
Abstract
Die Transformation der Planwirtschaften Osteuropas in markwirtschaftliche Systeme, die Integration Ost- und Westeuropas und die deutsche Wiedervereinigung waren recht einmalige politische und gesellschaftliche Prozesse. Es gab keine „Evidenz“ aus früheren Zeiten, an denen sich die handelnden Akteure orientieren konnten. Zeigt dies die Grenzen evidenzbasierter Politik auf? Einer Politik, die Maßnahmen vorab evaluiert, deren Wirkungen beobachtet und aus diesen empirischen Beobachtungen systematisch Schlüsse für zukünftiges politisches Handeln zieht? In einem eng definierten Sinn evidenzbasierter Politik muss die Antwort auf diese Frage sicherlich „Ja“ lauten. Es gibt Grenzen evidenzbasierter Politik in Zeiten großer gesellschaftlicher Umwälzungen und wenn (wirtschafts-)politische Maßnahmen so weit aus dem Rahmen des bisher Bekannten heraustreten, dass Verhaltensmuster der Vergangenheit kaum Rückschlüsse auf zukünftiges Verhalten zulassen. In solchen Phasen sind alle sozialwissenschaftlichen Disziplinen gefordert, politische Prozesse aus einem breiten Fundus an Wissen und Erfahrungen heraus zu begleiten. Empirisch messbare Effekte einzelner Maßnahmen sind in solchen Umbruchzeiten nicht verfügbar. So verstanden könnten Überlegungen zur Rolle evidenzbasierter Politik generell und speziell zur Frage, wie Finanzmärkte zur Transformation von wirtschaftlichen Systemen beitragen, schnell enden.

IWH issues warning of a new banking crisis
The coronavirus recession could mean the end for dozens of banks across Germany – even if Germany survives the economic crisis relatively unscathed. An analysis by the Halle Institute for Economic Research (IWH) shows that many savings banks and cooperative banks are particularly at risk. Loans worth hundreds of billions of euros are on the balance sheets of the financial institutions concerned. IWH President Gropp warns of a potentially high additional burden for the already weakened real economy.

The Corona Recession and Bank Stress in Germany
Reint E. Gropp, Michael Koetter, William McShane
IWH Online,
No. 4,
2020
Abstract
We conduct stress tests for a large sample of German banks across different recoveries from the Corona recession. We find that, depending on how quickly the economy recovers, between 6% to 28% of banks could become distressed from defaulting corporate borrowers alone. Many of these banks are likely to require regulatory intervention or may even fail. Even in our most optimistic scenario, bank capital ratios decline by nearly 24%. The sum of total loans held by distressed banks could plausibly range from 127 to 624 billion Euros and it may take years before the full extent of this stress is observable. Hence, the current recession could result in an acute contraction in lending to the real economy, thereby worsening the current recession , decelerating the recovery, or perhaps even causing a “double dip” recession. Additionally, we show that the corporate portfolio of savings and cooperative banks is more than five times as exposed to small firms as that of commercial banks and Landesbanken. The preliminary evidence indicates small firms are particularly exposed to the current crisis, which implies that cooperative and savings banks are at especially high risk of becoming distressed. Given that the financial difficulties may seriously impair the recovery from the Covid-19 crisis, the pressure to bail out large parts of the banking system will be strong. Recent research suggests that the long run benefits of largely resisting these pressures may be high and could result in a more efficient economy.

Corona Shutdown and Bankruptcy Risk
Oliver Holtemöller, Yaz Gulnur Muradoglu
IWH Online,
No. 3,
2020
Abstract
This paper investigates the consequences of shutdowns during the Corona crisis on the risk of bankruptcy for firms in Germany and United Kingdom. We use financial statements from the period 2014 to 2018 to predict how pervasive risk of bankruptcy becomes for micro, small, medium, and large firms due to shutdown measures. We estimate distress for firms using their capacity to service their debt. Our results indicate that under three months of shutdown almost all firms in shutdown industries face high risk of bankruptcy. In Germany, about 99% of firms in shutdown industries and in the UK about 98% of firms in shutdown industries are predicted to be under distress. The furlough schemes reduce the risk of bankruptcy only marginally to 97% of firms in shutdown industries in Germany and 95% of firms in shutdown industries in the United Kingdom in case of a three-month shutdown. In sectors that are not shutdown under conservative estimates of contagion of sales losses, our results indicate considerable risk of widespread bankruptcies ranging from 76% of firms in Germany to 69% of firms in the United Kingdom. These early findings suggest that the impact of corona crisis on corporate sector via shutdowns can be severe and subsequent policy should be designed accordingly.

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

IWH Online,
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.
