Power Generation and Structural Change: Quantifying Economic Effects of the Coal Phase-out in Germany
Christoph Schult, Katja Heinisch, Oliver Holtemöller
Abstract
In the fight against global warming, the reduction of greenhouse gas emissions is a major objective. In particular, a decrease in electricity generation by coal could contribute to reducing CO2 emissions. We study potential economic consequences of a coal phase-out in Germany, using a multi-region dynamic general equilibrium model. Four regional phase-out scenarios before the end of 2040 are simulated. We find that the worst case phase-out scenario would lead to an increase in the aggregate unemployment rate by about 0.13 [0.09 minimum; 0.18 maximum] percentage points from 2020 to 2040. The effect on regional unemployment rates varies between 0.18 [0.13; 0.22] and 1.07 [1.00; 1.13] percentage points in the lignite regions. A faster coal phase-out can lead to a faster recovery. The coal phase-out leads to migration from German lignite regions to German non-lignite regions and reduces the labour force in the lignite regions by 10,100 [6,300; 12,300] people by 2040. A coal phase-out until 2035 is not worse in terms of welfare, consumption and employment compared to a coal-exit until 2040

History, Microdata, and Endogenous Growth
Ufuk Akcigit, Tom Nicholas
Annual Review of Economics,
2019
Abstract
The study of economic growth is concerned with long-run changes, and therefore, historical data should be especially influential in informing the development of new theories. In this review, we draw on the recent literature to highlight areas in which study of history has played a particularly prominent role in improving our understanding of growth dynamics. Research at the intersection of historical data, theory, and empirics has the potential to reframe how we think about economic growth in much the same way that historical perspectives helped to shape the first generation of endogenous growth theories.

East Germany Three Decades After the Wall Came Down: What has Been Achieved and What Should Economic Policy Do?

No. 7,

Abstract
Dass Ostdeutschland bei der Verringerung der Ost-West-Produktivitätslücke nur noch wenig vorankommt, hat nicht nur mit fehlenden Konzernzentralen zu tun. Eine Produktivitätslücke existiert in Betrieben aller Größen. Sie ist im städtischen Raum größer als im ländlichen. Der Fachkräftemangel ist der neue Entwicklungsengpass. Um gegenzusteuern, sollte die Wirtschaftspolitik nicht durch zusätzliche Subventionen, die an die Arbeitsplatzschaffung und -erhaltung gebunden sind, den Produktivitätsdruck abschwächen. Die Produktivitätspotenziale der ostdeutschen Städte gilt es zu heben. Fachkräftesicherung verlangt qualifizierte Zuwanderung mit einer entsprechenden Willkommenskultur in Ostdeutschland.

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

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.

Motivating High‐impact Innovation: Evidence from Managerial Compensation Contracts

No. 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.

Zu den Effekten eines beschleunigten Braunkohleausstiegs auf Beschäftigung und regionale Arbeitnehmerentgelte

Abstract
Ohne weitere staatliche Maßnahmen können die Klimaschutzziele der Bundesregierung nicht erreicht werden. Eine Möglichkeit, Emissionen zu reduzieren, ist der Ausstieg aus der Braunkohleverbrennung. Die Braunkohlenwirtschaft zahlt allerdings doppelt so hohe Löhne im Vergleich zum durchschnittlichen Lohnniveau. Der Braunkohleausstieg wird voraussichtlich Einkommenseinbußen und Abwanderung aus den Braunkohleregionen mit sich bringen.

Do Diasporas Affect Regional Knowledge Transfer within Host Countries? A Panel Analysis of German R&D Collaborations

Regional Studies,
No. 1,
2019
Abstract
Interactive regional learning involving various actors is considered a precondition for successful innovations and, hence, for regional development. Diasporas as non-native ethnic groups are regarded as beneficial since they enrich the creative class by broadening the cultural base and introducing new routines. Using data on research and development (R&D) collaboration projects, the analysis provides tentative evidence that the size of diasporas positively affects the region’s share of outward R&D linkages enabling the exchange of knowledge. The empirical analysis further confirms that these interactions mainly occur between regions hosting the same diasporas, pointing to a positive effect of ethnic proximity rather than ethnic diversity.

Identifying Cooperation for Innovation – A Comparison of Data Sources
Michael Fritsch, Matthias Piontek, Mirko Titze
Abstract
The value of social network analysis is critically dependent on the comprehensive and reliable identification of actors and their relationships. We compare regional knowledge networks based on different types of data sources, namely, co-patents, co-publications, and publicly subsidised collaborative Research and Development projects. Moreover, by combining these three data sources, we construct a multilayer network that provides a comprehensive picture of intraregional interactions. By comparing the networks based on the data sources, we address the problems of coverage and selection bias. We observe that using only one data source leads to a severe underestimation of regional knowledge interactions, especially those of private sector firms and independent researchers. The key role of universities that connect many regional actors is identified in all three types of data.

Trust in Banks
Zuzana Fungáčová, Iftekhar Hasan, Laurent Weill
Journal of Economic Behavior and Organization,
2019
Abstract
Trust in banks is considered essential for an effective financial system, yet little is known about what determines trust in banks. Only a handful of single-country studies discuss the topic, so this paper aims to fill the gap by providing a cross-country analysis on the level and determinants of trust in banks. Using World Values Survey data covering 52 countries during the period 2010–2014, we observe large cross-country differences in trust in banks and confirm the influence of several sociodemographic indicators. Our main findings include: women tend to trust banks more than men; trust in banks tends to increase with income, but decrease with age and education; and access to television enhances trust, while internet access erodes trust. Additionally, religious, political, and economic values affect trust in banks. Notably, religious individuals tend to put greater trust in banks, but differences are observed across denominations. The holding of pro-market economic views is also associated with greater trust in banks.

Innovation and Top Income Inequality

Abstract
In this article, we use cross-state panel and cross-U.S. commuting-zone data to look at the relationship between innovation, top income inequality and social mobility. We find positive correlations between measures of innovation and top income inequality. We also show that the correlations between innovation and broad measures of inequality are not significant. Next, using instrumental variable analysis, we argue that these correlations at least partly reflect a causality from innovation to top income shares. Finally, we show that innovation, particularly by new entrants, is positively associated with social mobility, but less so in local areas with more intense lobbying activities.
