IWH-Gutachten: Regionalförderung wirkt, sollte aber weiter verbessert werden
Deutschlands wichtigstes Instrument der Regionalpolitik fördert Arbeitsplätze, erhöht Betriebsumsätze und moderat auch die Löhne; es hat jedoch keine positiven Effekte auf die Produktivität. Das zeigt ein Gutachten zur Wirkung der Bund-Länder-Gemeinschaftsaufgabe „Verbesserung der regionalen Wirtschaftsstruktur“ (GRW), verfasst vom Leibniz-Institut für Wirtschaftsforschung Halle (IWH). Daher empfehlen die Ökonomen, die Förderziele stärker auf die Produktivität auszurichten, denn nur so kann das Förderziel, dass die geförderten Regionen wirtschaftlich aufholen, erreicht werden.

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.

The Value of Firm Networks: A Natural Experiment on Board Connections
Ester Faia, Maximilian Mayer, Vincenzo Pezone
CEPR Discussion Papers,
Nr. 14591,
2020
Abstract
This paper presents causal evidence of the effects of boardroom networks on firm value and compensation policies. We exploit exogenous variation in network centrality arising from a ban on interlocking directorates of Italian financial and insurance companies. We leverage this shock to show that firms whose centrality in the network rises after the reform experience positive abnormal returns around the announcement date and are better hedged against shocks. Information dissemination plays a central role: results are driven by firms that have higher idiosyncratic volatility, low analyst coverage, and more uncertainty surrounding their earnings forecasts. Firms benefit more from boardroom centrality when they are more central in the input-output network, hence more susceptible to upstream shocks, when they are less central in the cross-ownership network, or when they have low profitability or low growth opportunities. Network centrality also results in higher directors' compensation, due to rent sharing and improved executives' outside option, and more similar compensation policies between connected firms.

Coal Phase-out in Germany – Implications and Policies for Affected Regions

Energy,
April
2020
Abstract
The present study examines the consequences of the planned coal phase-out in Germany according to various phase-out pathways that differ in the ordering of power plant closures. Soft-linking an energy system model with an input-output model and a regional macroeconomic model simulates the socio-economic effects of the phase-out in the lignite regions, as well as in the rest of Germany. The combination of two economic models offers the advantage of considering the phase-out from different perspectives and thus assessing the robustness of the results. The model results show that the lignite coal regions will exhibit losses in output, income and population, but a faster phase-out would lead to a quicker recovery. Migration to other areas in Germany and demographic changes will partially compensate for increasing unemployment, but support from federal policy is also necessary to support structural change in these regions.

Intangible Capital and Productivity. Firm-level Evidence from German Manufacturing
Wolfhard Kaus, Viktor Slavtchev, Markus Zimmermann
IWH Discussion Papers,
Nr. 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%.

Kurzfristige ökonomische Effekte eines „Brexit“ auf die deutsche Wirtschaft - Studie im Auftrag des Bundesministeriums für Wirtschaft und Energie

Abstract
Viele Fragen rund um den Brexit sind weiterhin offen. Es kann nicht ausgeschlossen werden, dass sich Großbritannien und die Europäische Union nicht auf einen Austrittsvertrag einigen können. Dann könnte es zu einem sogenannten harten Brexit (No-Deal Brexit) kommen. Wir haben die kurzfristigen Effekte eines harten Brexit für die deutsche Wirtschaft untersucht. Effekte über den Handelskanal werden zunächst auf Basis einer Input-Output-Analyse der internationalen und sektoralen Verflechtungen auf 0,3% in Relation zum Bruttoinlandsprodukt geschätzt. Diese Größenordnung ergibt sich auch aus dem internationalen Konjunkturmodell des IWH, mit dem auch makroökonomische Rückwirkungen berücksichtigt werden. Mit einem harten Brexit entstünde neben den Handelsbarrieren ein erhebliches Verunsicherungspotenzial für Unternehmer und private Haushalte. Dies wirkt sich nachfrageseitig negativ auf die Investitionstätigkeit und den privaten Verbrauch aus. Für sich genommen belaufen sich diese Effekte auf 0,1% des Bruttoinlandsproduktes. Insgesamt könnte das deutsche Bruttoinlandsprodukt in den ein bis zwei Jahren nach einem harten Brexit um mehrere zehntel Prozentpunkte gedämpft werden. Am stärksten wäre wohl die Automobilbranche betroffen. Empfehlungen für diskretionäre konjunkturpolitische Maßnahmen, die auf die Dämpfung der kurzfristigen gesamtwirtschaftlichen Effekte oder auf einzelne Wirtschaftszweige abzielen, lassen sich daraus nicht ableiten. Die automatischen Stabilisatoren sind angesichts der erwarteten Größenordnung der Effekte ausreichend.

Structural Stability of the Research & Development Sector in European Economies Despite the Economic Crisis
Jutta Günther, Maria Kristalova, Udo Ludwig
Journal of Evolutionary Economics,
Nr. 5,
2019
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.

Beschäftigungs- und Lohneffekte der deutschen Exportgüterproduktion im Lichte ihrer gestiegenen Importintensität

Abstract
Anhand einer Input-Output-Analyse wird gezeigt, dass für die Wertschöpfungsketten der Exportgüterproduktion in Deutschland weder die Daten während des Globalisierungsschubs um die Jahrtausendwende noch die Daten während der Wirtschafts- und Finanzkrise und danach den Verlust an Arbeitsplätzen und Einkommen infolge der wachsenden Importdurchdringung der nationalen Produktion belegen können. Im Gegenteil wird gezeigt, dass Deutschland dank seiner Stärke auf den internationalen Märkten von der Auslagerung einzelner Arbeitsschritte und ganzer Produktionsstufen profitiert hat.

Motivating High‐impact Innovation: Evidence from Managerial Compensation Contracts
Bill Francis, Iftekhar Hasan, Zenu Sharma, Maya Waisman
Financial Markets, Institutions and Instruments,
Nr. 3,
2019
Abstract
We investigate the relationship between Chief Executive Officer (CEO) compensation and firm innovation and find that long‐term incentives in the form of options, especially unvested options, and protection from managerial termination in the form of golden parachutes are positively related to corporate innovation, and particularly to high‐impact, exploratory (new knowledge creation) invention. Conversely, non‐equity pay has a detrimental effect on the input, output and impact of innovation. Tests using the passage of an option expensing regulation (FAS 123R) as an exogenous shock to option compensation suggest a causal interpretation for the link between long‐term pay incentives, patents and citations. Furthermore, we find that the decline in option pay following the implementation of FAS 123R has led to a significant reduction in exploratory innovation and therefore had a detrimental effect on innovation output. Overall, our findings support the idea that compensation contracts that protect from early project failure and incentivize long‐term commitment are more suitable for inducing high‐impact corporate innovation.
