Abstract
Mit zunehmend zeitlichem Abstand seit der Wiederentstehung eines vereinten Deutschlands schwindet im Alltag das Wissen und in Forschung und Lehre das Verständnis der bewegenden Kräfte um dieses historisch einmalige und bis in die Gegenwart nachwirkende Ereignis. Die Zeitzeugen und die Mitgestalter der damit verbundenen Transformation einer Zentralplanwirtschaft verlassen altersbedingt die Bühne, und die nachrückenden Generationen wenden sich anderen Herausforderungen zu. Denn heute stehen erneut, aber ganz anders geartete Transformationsprozesse auf der Tagesordnung: Gefragt sind Antworten auf den Klimawandel, den Ausstieg aus der Energiegewinnung durch fossile Brennstoffe, die Digitalisierung der Produktions- und Verbrauchsprozesse, die Verkehrswende und anderes. Schnell wird dann die Transformation einer ganzen Wirtschaftsordnung von der Agenda verdrängt, und die systemischen Zusammenhänge sowie das Verständnis der längerfristigen Folgen dieses historischen Wendepunktes für Deutschland treten in den Hintergrund und geben den Platz frei für oberflächliche Vereinfachungen. Der Systemwechsel verschwindet im sprachlichen Alltag hinter Schlagworten wie “Wende” und Ost-West-Vergleiche, in denen historische Bruchstellen geglättet bzw. sozioökonomische Inhalte durch die Projektion auf Himmelsrichtungen ersetzt werden. Selbstverständlichkeiten aus der Zeit des Umbruchs gehen unter oder werden durch Halbwahrheiten verzerrt wiedergegeben.

Der Produktivitätsrückstand der ostdeutschen Industrie: Nur eine Frage der Preise?

Contribution to IWH Volume,
Festschrift für Gerhard Heimpold, IWH
2020
Abstract
Die volkswirtschaftliche Gesamtrechnung zeigt auch knapp drei Jahrzehnte nach der Deutschen Einheit, dass die Arbeitsproduktivität in Ostdeutschlands Industrie mehr als 20% unter dem westdeutschen Niveau verharrt. In dieser Arbeit gehe ich der Frage nach, ob dieser Rückstand die Folge einer geringeren physischen Produktivität oder niedrigerer Preise für ostdeutsche Erzeugnisse ist. Dazu werden Mikrodaten auf Firmenebene benutzt, die Informationen zu produzierten Gütermengen und erzielten Preisen enthalten. Der Rückstand in der Erlösproduktivität wird auch mit diesen Daten bestätigt. Die Hauptergebnisse sind, dass i) ostdeutsche Industrieunternehmen tatsächlich deutlich geringere Marktpreise erlösen und ii) der physische Output bei gleichen Inputmengen im Osten höher liegt als im Westen. Eine naheliegende Erklärung für beide Befunde ist, dass ostdeutsche Produkte weniger Kundennutzen generieren und gleichzeitig in weniger aufwändigen Produktionsverfahren hergestellt werden können. Weitere Tests zeigen, dass iii) die Hypothese verlängerter Werkbänke keine Erklärung für den ostdeutschen Produktivitätsrückstand ist und iv) ostdeutsche Betriebe im Vergleich zur westdeutschen Konkurrenz eine geringere physische Produktivität aufweisen, wenn sie Güter zu westdeutschen Preisen herstellen.

Cross-country Evidence on the Relationship between Regulations and the Development of the Life Insurance Sector

Vol. 89 (July),
2020
Abstract
Using a global sample, this study sketches the impact of insurance regulations on the life insurance sector, revealing a significant negative association between supervisory control on policy conditions of life annuities as well as pension products and the development of the industry. A similar inverse relation is observed between the index of capital requirements and insurance development. These results hold when we control for demographic factors, economic factors, religious inclination, culture, as well as for other relevant regulations. We also find some evidence that while the overall supervisory power does not matter, the ability to intervene at an early stage could have a positive effect on insurance development. Additionally, the impact of some regulations appears to differ between advanced and developing countries.

Employment Effects of Introducing a Minimum Wage: The Case of Germany
Oliver Holtemöller, Felix Pohle
Economic Modelling,
Vol. 89 (July),
2020
Abstract
Income inequality has been a major concern of economic policy makers for several years. Can minimum wages help to mitigate inequality? In 2015, the German government introduced a nationwide statutory minimum wage to reduce income inequality by improving the labour income of low-wage employees. However, the employment effects of wage increases depend on time and region specific conditions and, hence, they cannot be known in advance. Because negative employment effects may offset the income gains for low-wage employees, it is important to evaluate minimum-wage policies empirically. We estimate the employment effects of the German minimum-wage introduction using panel regressions on the state-industry-level. We find a robust negative effect of the minimum wage on marginal and a robust positive effect on regular employment. In terms of the number of jobs, our results imply a negative overall effect. Hence, low-wage employees who are still employed are better off at the expense of those who have lost their jobs due to the minimum wage.

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.

High risk of corporate bankruptcy due to the corona shutdown
The Corona shutdown increases the probability of corporate bankruptcy. An analysis based on corporate financial statements from 2014 to 2018 reveals that in the United Kingdom, 73% of shutdown firms are not able to cover interest expenses from earnings before interest and taxes if they lose one twelfth of annual turnover. In Germany, the fraction amounts to 81%.

Credit Allocation when Borrowers are Economically Linked: An Empirical Analysis of Bank Loans to Corporate Customers
Iftekhar Hasan, Kristina Minnick, Kartik Raman
Journal of Corporate Finance,
Vol. 62 (June),
2020
Abstract
Using detailed loan level data, we examine bank lending to corporate customers relying on principal suppliers. Customers experience larger loan spreads, higher intensity of covenants and greater likelihood of requiring collateral when they depend more on the principal supplier for inputs. The positive association between the customer’s loan spread and its dependence on the principal supplier is less pronounced when the bank has a prior loan outstanding with the principal supplier, and when the bank has higher market share in the industry. Longer relationships between the customer and its principal supplier, and between the bank and the principal supplier, mitigate lending constraints. The evidence is consistent with corporate suppliers serving as an informational bridge between the lender and the customer.
