Economy recovers from the shutdown – but a quick return to pre-crisis normality is unlikely
The German economy has bounced back strongly over the summer, recovering a considerable part of the production slump caused by the shutdown in spring. Nevertheless, real gross domestic product in 2020 is likely to contract by 5.7%. In 2021, growth is expected to average 3.2% according to IWH autumn economic forecast. The decline in production in 2020 is likely to be less pronounced in East Germany com¬pared to Germany as a whole.

The East-West German Gap in Revenue Productivity: Just a Tale of Output Prices?
Matthias Mertens, Steffen Müller
Abstract
East German manufacturers’ revenue productivity (value-added per worker) is some 8 (25) percent below West German levels, even three decades after German unification. Using firm-product-level data containing information on product quantities and prices, we analyse the role of product specialisation and reject the prominent ‚extended work bench hypothesis‘, stating a specialisation of Eastern firms in the intermediate input production as explanation for these sustained productivity differences. We decompose the East’s revenue productivity disadvantage into Eastern firms selling at lower prices and producing more physical output for given amounts of inputs within ten-digit product industries. This suggests that Eastern firms specialise vertically in simpler product varieties generating less consumer value but being manufactured with less or cheaper inputs. Vertical specialisation, however, does not explain the productivity gap as Eastern firms are physically less productive for given product prices, implying a genuine physical productivity disadvantage of Eastern compared to Western firms

Abstract
Die „Gemeinschaftaufgabe ‚Verbesserung der regionalen Wirtschaftsstruktur‘ (GRW)“ repräsentiert das wichtigste Instrument der Regionalpolitik in Deutschland. Das Förderprogramm gewährt nicht-rückzahlbare Zuschüsse als Anteilsfinanzierung für Investitionsprojekte von Betriebsstätten (und Kommunen) im GRW-Fördergebiet. Die Festlegung des Fördergebiets erfolgt anhand eines aus verschiedenen Teilindikatoren zusammengesetzten Strukturschwächeindikators und eines von der Europäischen Union festgelegten Anteils der in Fördergebieten lebenden Bevölkerung. Verantwortlich für die Auswahl der geförderten Projekte ist das jeweilige Land, in dem das GRW-Projekt beantragt wird.

Der Produktivitätsrückstand der ostdeutschen Industrie: Nur eine Frage der Preise?
Steffen Müller
Beitrag in IWH-Sammelwerk,
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.

Employment Effects of Introducing a Minimum Wage: The Case of Germany
Oliver Holtemöller, Felix Pohle
Economic Modelling,
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.

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.

Does Low-pay Persist across Different Regimes? Evidence from the German Unification
André Diegmann, Nicole Gürtzgen
Economics of Transition and Institutional Change,
No. 3,
2020
Abstract
Using German administrative data, we study across-regime low-pay persistence in the context of an economic transformation process. We first show that individuals' initial allocation to the post-unification low-wage sector was close to random in terms of market-regime unobservables. Consistent with a weak connection between individuals' true productivity and their pre-unification low-wage status, the extent of across-regime state dependence is found to be small and appears to vanish over time. For males, across-regime state dependence is most pronounced among the medium- and high-skilled, suggesting the depreciation of human capital as an explanation.

Intangible Capital and Productivity. Firm-level Evidence from German Manufacturing
Wolfhard Kaus, Viktor Slavtchev, Markus Zimmermann
IWH Discussion Papers,
No. 1,
2020
Abstract
We study the importance of intangible capital (R&D, software, patents) for the measurement of productivity using firm-level panel data from German manufacturing. We first document a number of facts on the evolution of intangible investment over time, and its distribution across firms. Aggregate intangible investment increased over time. However, the distribution of intangible investment, even more so than that of physical investment, is heavily right-skewed, with many firms investing nothing or little, and a few firms having very large intensities. Intangible investment is also lumpy. Firms that invest more intensively in intangibles (per capita or as sales share) also tend to be more productive. In a second step, we estimate production functions with and without intangible capital using recent control function approaches to account for the simultaneity of input choice and unobserved productivity shocks. We find a positive output elasticity for research and development (R&D) and, to a lesser extent, software and patent investment. Moreover, the production function estimates show substantial heterogeneity in the output elasticities across industries and firms. While intangible capital has small effects for firms with low intangible intensity, there are strong positive effects for high-intensity firms. Finally, including intangibles in a gross output production function reduces productivity dispersion (measured by the 90-10 decile range) on average by 3%, in some industries as much as nearly 9%.
