IWH untersucht Folgen des Kohleausstiegs in Europa
Wie verändert der Kohleausstieg die Gesellschaft – und wie kann Politik darauf reagieren? Diese Fragen untersuchen
14 europäische Partner in einem neuen interdisziplinären Forschungsprojekt. Dabei wird das Leibniz-Institut für Wirtschaftsforschung Halle (IWH) ökonomische Folgen wie Arbeitslosigkeit und Abwanderung für ausgewählte Kohleregionen Europas analysieren. Die EU fördert das Gesamtprojekt für drei Jahre mit knapp drei Millionen Euro.

Total Factor Productivity and the Terms of Trade
Jan Teresinski
IWH-CompNet Discussion Papers,
Nr. 6,
2019
Abstract
In this paper we analyse how the terms of trade (TOT) – the ratio of export prices to import prices – affect total factor productivity (TFP). We provide empirical macroeconomic evidence for the European Union countries based on the times series SVAR analysis and microeconomic evidence based on industry level data from the Competitiveness Research Network (CompNet) database which shows that the terms of trade improvements are associated with a slowdown in the total factor productivity growth. Next, we build a theoretical model which combines open economy framework with the endogenous growth theory. In the model the terms of trade improvements increase demand for labour employed in exportable goods production at the expense of technology production (research and development – R&D) which leads to a shift of resources from knowledge development towards physical exportable goods. This reallocation has a negative impact on the TFP growth. Under a plausible calibration the model is able to replicate the observed empirical pattern.

Studie: Wie Finanzkrisen Menschen unzufriedener machen und wie sich das verhindern lässt
Finanzkrisen haben nicht nur starke Verwerfungen im ökonomischen System zur Folge: Sie beeinflussen auch direkt die Lebenszufriedenheit der Menschen. Am stärksten betroffen sind die Schwachen der Gesellschaft, auch wenn diese unter Umständen gar nicht selbst mit Aktien spekulieren. Das ist das Ergebnis einer neuen Studie der Martin-Luther-Universität Halle-Wittenberg (MLU) und des Leibniz-Instituts für Wirtschaftsforschung Halle (IWH). Diese negativen Folgen könnten die Kauflust der Menschen schmälern und die Wirkung der Krise sogar noch verstärken. Die Studie wurde kürzlich in der Fachzeitschrift „The B.E. Journal of Economic Analysis & Policy“ veröffentlicht.

Delay Determinants of European Banking Union Implementation
Michael Koetter, Thomas Krause, Lena Tonzer
European Journal of Political Economy,
2019
Abstract
Most countries in the European Union (EU) delay the transposition of European Commission (EC) directives, which aim at reforming banking supervision, resolution, and deposit insurance. We compile a systematic overview of these delays to investigate if they result from strategic considerations of governments conditional on the state of their financial, regulatory, and political systems. Transposition delays pertaining to the three Banking Union directives differ considerably across the 28 EU members. Bivariate regression analyses suggest that existing national bank regulation and supervision drive delays the most. Political factors are less relevant. These results are qualitatively insensitive to alternative estimation methods and lag structures. Multivariate analyses highlight that well-stocked deposit insurance schemes speed-up the implementation of capital requirements, banking systems with many banks are slower in implementing new bank rescue and resolution rules, and countries with a more intensive sovereign-bank nexus delay the harmonization of EU deposit insurance more.

Price-cost Margin and Bargaining Power in the European Union
Ana Cristina Soares
IWH-CompNet Discussion Papers,
Nr. 4,
2019
Abstract
Using firm-level data between 2004 and 2012 for eleven countries of the European Union (EU), we document the size of product and labour market imperfections within narrowly defined sectors including services which are virtually undocumented. Our findings suggest that perfect competition in both product and labour markets is widely rejected. Levels of the price-cost margin and union bargaining power tend to be higher in some service sectors depicting however substantial heterogeneity. Dispersion within sector and across countries tends to be higher in some services sectors assuming a less tradable nature which suggests that the Single Market integration is partial particularly relaxing the assumption of perfect competition in the labour market. We report also figures for the aggregate economy and show that Eastern countries tend to depict lower product and labour market imperfections compared to other countries in the EU. Also, we provide evidence in favour of a very limited adjustment of both product and labour market imperfections following the international and financial crisis.

Drivers of Systemic Risk: Do National and European Perspectives Differ?
Claudia M. Buch, Thomas Krause, Lena Tonzer
Journal of International Money and Finance,
March
2019
Abstract
With the establishment of the Banking Union, the European Central Bank has been granted the power to impose stricter regulations than the national regulator if systemic risks are not adequately addressed at the national level. We ask whether there is a cross-border externality in the sense that a bank’s systemic risk differs when applying a national versus a European perspective. On average, banks’ contribution to systemic risk is similar at the two regional levels, and so is the ranking of banks. Generally, larger banks and banks with a lower share of loans are more systemically important. The effects of these variables are qualitatively but not quantitatively similar at the national versus the European level.

Potential International Employment Effects of a Hard Brexit
Hans-Ulrich Brautzsch, Oliver Holtemöller
Abstract
We use the World Input Output Database (WIOD) to estimate the potential employment effects of a hard Brexit in 43 countries. In line with other studies we assume that imports from the European Union (EU) to the UK will decline by 25% after a hard Brexit. The absolute effects are largest in big EU countries which have close trade relationships with the UK like Germany and France. However, there are also large countries outside the EU which are heavily affected via global value chains like China, for example. The relative effects (in percent of total employment) are largest in Malta and Ireland. UK employment will also be affected via intermediate input production. Within Germany, the motor vehicle industry and in particular the “Autostadt” Wolfsburg are most affected.

IWH leitet millionenschweres EU-Forschungsprojekt zur Produktivität
Verliert das Produktivitätswachstum in den Industrieländern an Schwung? Und wenn ja, warum? Mit diesen Fragen, die für die gesamte Wirtschaft von zentraler Bedeutung sind, befasst sich das Leibniz-Institut für Wirtschaftsforschung Halle (IWH) ab Jahresbeginn 2019 als Koordinator eines neuen EU-Projekts. Unter dem Titel MICROPROD arbeiten Ökonomen und Statistikexperten neun europäischer Partner für drei Jahre zusammen. Mit einem Gesamtbudget von knapp drei Millionen Euro ist es das bislang größte EU-Projekt am IWH.

Secrecy, Information Shocks, and Corporate Investment: Evidence from European Union Countries
Mohamad Mazboudi, Iftekhar Hasan
Journal of International Financial Markets, Institutions and Money,
2018
Abstract
This study examines how national culture affects corporate investment. We argue that national culture affects corporate investment efficiency through the level of secrecy that national culture exhibits. Using a sample of firms from eight culturally-diverse European Union countries, we find that the level of secrecy that national culture exhibits is negatively related to corporate investment efficiency after controlling for a number of firm- and country-level factors. We also find that the negative relation between national culture and corporate investment efficiency is mitigated by an exogenous shock to the information asymmetry problem between managers and investors. Our study highlights the importance of the cultural value of secrecy/transparency as a determinant of investment efficiency at the firm-level.
