Abstract
Ein Stopp der russischen Gaslieferungen würde zu einer Rezession der deutschen Wirtschaft führen. Nicht alle Regionen wären davon gleich betroffen: Vor allem wäre dort, wo das Verarbeitende Gewerbe ein großes Gewicht hat, mit einem deutlich stärkeren Einbruch der Wirtschaftsleistung zu rechnen als andernorts. Deshalb wäre Westdeutschland und dort insbesondere der Süden stärker betroffen als der Osten Deutschlands. Dagegen spielt für die Frage, wie viele Arbeitsplätze durch einen bestimmten Rückgang der Wertschöpfung gefährdet sind, die Höhe der Arbeitsproduktivität eine ausschlaggebende Rolle.

Trade Shocks, Labour Markets and Elections in the First Globalisation
Richard Bräuer, Wolf-Fabian Hungerland, Felix Kersting
Abstract
This paper studies the economic and political effects of a large trade shock in agriculture – the grain invasion from the Americas – in Prussia during the first globalisation (1871-1913). We show that this shock accelerated the structural change in the Prussian economy through migration of workers to booming cities. In contrast to studies using today’s data, we do not observe declining per capita income and political polarisation in counties affected by foreign competition. Our results suggest that the negative and persistent effects of trade shocks we see today are not a universal feature of globalisation, but depend on labour mobility. For our analysis, we digitise data from Prussian industrial and agricultural censuses on the county level and combine it with national trade data at the product level. We exploit the cross-regional variation in cultivated crops within Prussia and instrument with Italian trade data to isolate exogenous variation.

International Trade Barriers and Regional Employment: The Case of a No-Deal Brexit

Journal of Economic Structures,
No. 11,
2021
Abstract
We use the World Input–Output Database (WIOD) combined with regional sectoral employment data to estimate the potential regional employment effects of international trade barriers. We study the case of a no-deal Brexit in which imports to the United Kingdom (UK) from the European Union (EU) would be subject to tariffs and non-tariff trade costs. First, we derive the decline in UK final goods imports from the EU from industry-specific international trade elasticities, tariffs and non-tariff trade costs. Using input–output analysis, we estimate the potential output and employment effects for 56 industries and 43 countries on the national level. The absolute effects would be largest in big EU countries which have close trade relationships with the UK, such as Germany and France. However, there would also be large countries outside the EU which would be heavily affected via global value chains, such as China, for example. The relative effects (in percent of total employment) would be largest in Ireland followed by Belgium. In a second step, we split up the national effects on the NUTS-2 level for EU member states and additionally on the county (NUTS-3) level for Germany. The share of affected workers varies between 0.03% and 3.4% among European NUTS-2 regions and between 0.15% and 0.4% among German counties. A general result is that indirect effects via global value chains, i.e., trade in intermediate inputs, are more important than direct effects via final demand.

Did GRW Investment Grants Contribute to the Catching-up of East Germany?

Abstract
The joint task force ‘Improving Regional Economic Structures’ (GRW) is the most important regional policy scheme in Germany and was extensively used to support the economic transformation process in the new states after reunification. The article provides an overview of national and international causal analytical studies on the effects of investment grants. The analysis shows that such programmes have positive effects on development — especially of employment and income. It not only affects the subsidised establishment benefit from this type of support, but the regions as a whole. Even though the studies do not go back to the early 1990s, we can conclude that the GRW contributed to economic development in East Germany — and to the catching-up process.

Identifying Cooperation for Innovation―a Comparison of Data Sources

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 subsidized collaborative R&D 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.

Transmitting Fiscal Covid-19 Counterstrikes Effectively: Mind the Banks!
Reint E. Gropp, Michael Koetter, William McShane
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.

Zu den betrieblichen Effekten der Investitionsförderung im Rahmen der deutschen Regionalpolitik
Matthias Brachert, Eva Dettmann, Mirko Titze
Wirtschaft im Wandel,
No. 1,
2020
Abstract
Die Wirtschaft in den Industrieländern unterliegt einem ständigen Anpassungsdruck. Wichtige aktuelle Treiber des Strukturwandels sind vor allem die Globalisierung, der technologische Fortschritt (insbesondere durch Digitalisierung und Automatisierung), die Demographie (durch Alterung und Schrumpfung der Bevölkerung) und der Klimawandel. Von diesem Anpassungsdruck sind jedoch die Regionen in Deutschland sehr unterschiedlich betroffen. Regionalpolitik verfolgt das Ziel, Regionen bei der Bewältigung des Strukturwandels zu unterstützen. Ein besonderer Fokus liegt dabei auf Regionen, die ohnehin durch Strukturschwächen gekennzeichnet sind. Die aktuelle Regionalförderung in Deutschland basiert im Wesentlichen auf der Förderung von Investitionen von Betrieben und Kommunen. Die Evaluierung dieser Programme muss integraler Bestandteil der Regionalpolitik sein – schließlich stellt sich immer die Frage nach einer alternativen Verwendung knapper öffentlicher Mittel. Eine Pilotstudie für Sachsen-Anhalt zeigt, dass die im Rahmen der Regionalpolitik gewährten Investitionszuschüsse einen positiven Effekt auf Beschäftigung und Investitionen der geförderten Betriebe haben; bei den Investitionen allerdings nur für die Dauer des Projekts. Effekte der Förderung auf Umsatz und Produktivität von Betrieben in Sachsen-Anhalt waren nicht nachweisbar.

Tornado Activity, House Price and Stock Returns

North American Journal of Economics and Finance,

2020
Abstract
In this paper we investigate the effects of tornado activity on house prices and stock returns in the US. First, using geo-referenced and metropolitan statistical area (MSA)-level data, we find tornado activity to be responsible for a significant drop in house prices. Spillover tornado effects between adjacent MSAs are also detected. Furthermore, our granular analysis provides evidence of tornadoes having a negative impact on stock returns. However, only two sectors seem to contribute to such a negative effect (i.e., consumer discretionary and telecommunications). In a macro-analysis, which relies on aggregate data for the South, West, Midwest and Northeast US regions, we then show that tornado activity generates a significant drop in house prices only in the South and Midwest. In these regions, tornadoes are also responsible for a drop in income. Tornado activity is finally found to positively (negatively) affect stock returns in the Midwest (South). If different sectors are examined, a more heterogeneous picture emerges.

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

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.
