Drawing Conclusions from Structural Vector Autoregressions Identified on the Basis of Sign Restrictions
Christiane Baumeister, James D. Hamilton
Abstract
This paper discusses the problems associated with using information about the signs of certain magnitudes as a basis for drawing structural conclusions in vector autoregressions. We also review available tools to solve these problems. For illustration we use Dahlhaus and Vasishtha's (2019) study of the effects of a U.S. monetary contraction on capital flows to emerging markets. We explain why sign restrictions alone are not enough to allow us to answer the question and suggest alternative approaches that could be used.

Structural Stability of the Research & Development Sector in European Economies Despite the Economic Crisis
Jutta Günther, Maria Kristalova, Udo Ludwig
Journal of Evolutionary Economics,
No. 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.

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.

Do Diasporas Affect Regional Knowledge Transfer within Host Countries? A Panel Analysis of German R&D Collaborations
Lutz Schneider, Alexander Kubis, Mirko Titze
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.

Did the Swiss Exchange Rate Shock Shock the Market?
Manuel Buchholz, Gregor von Schweinitz, Lena Tonzer
Abstract
The Swiss National Bank abolished the exchange rate floor versus the Euro in January 2015. Based on a synthetic matching framework, we analyse the impact of this unexpected (and therefore exogenous) shock on the stock market. The results reveal a significant level shift (decline) in asset prices in Switzerland following the discontinuation of the minimum exchange rate. While adjustments in stock market returns were most pronounced directly after the news announcement, the variance was elevated for some weeks, indicating signs of increased uncertainty and potentially negative consequences for the real economy.

Welche Faktoren verzögern die Umsetzung der Bankenunion?
Michael Koetter, Thomas Krause, Lena Tonzer
Wirtschaft im Wandel,
No. 1,
2018
Abstract
Die Europäische Kommission hat weitreichende Reformen zur Regulierung und Überwachung des europäischen Bankensektors beschlossen, um die Stabilität europäischer Banken zu gewährleisten. In den meisten Mitgliedsländern verzögert sich allerdings die Umsetzung der zugrunde liegenden Richtlinien der Europäischen Kommission. Dieser Beitrag geht den Gründen für diese Verzögerung nach. Es zeigt sich, dass insbesondere bereits existierende Regulierungen und institutionelle Rahmenbedingungen das Tempo der Umsetzung entscheidend bestimmen. Entgegen populären Meinungsäußerungen sind die Struktur der Bankensektoren in den Mitgliedstaaten und politische Faktoren hingegen von nachrangiger Bedeutung.

Delay Determinants of European Banking Union Implementation
Michael Koetter, Thomas Krause, Lena Tonzer
Abstract
To safeguard financial stability and harmonise regulation, the European Commission substantially reformed banking supervision, resolution, and deposit insurance via EU directives. But most countries delay the transposition of these directives. We ask if transposition delays result from strategic considerations of governments conditional on the state of their financial, regulatory, and political systems? Supervisors might try to protect national banking systems and local politicians maybe reluctant to surrender national sovereignty to deal with failed banks. Alternatively, intricate financial regulation might require more implementation time in large and complex financial and political systems. We therefore collect data on the transposition delays of the three Banking Union directives and investigate observed delay variation across member states. Our correlation analyses suggest that existing regulatory and institutional frameworks, rather than banking market structure or political factors, matter for transposition delays.

Messbar, aber milde: Auswirkungen des SMP-Wertpapier-Ankaufprogramms der EZB auf den regionalen Bankenwettbewerb in Deutschland
Friederike Altgelt, Michael Koetter
Wirtschaft im Wandel,
No. 3,
2017
Abstract
Die Europäische Zentralbank (EZB) hat mit dem Securities Markets Programme (SMP) im Mai 2010 ein Instrument unkonventioneller Geldpolitik eingeführt. Im Rahmen des SMP erwarb sie im Wert von 218 Mrd. Euro Staatsanleihen ausgewählter Länder, welche erhöhten Risikoaufschlägen am Kapitalmarkt ausgesetzt waren. Eine mögliche Nebenwirkung solcher Ankaufprogramme ist es, auch jene Banken zu stützen, die nicht zum direkten Adressatenkreis gehören, aber Anleihen betroffener Länder in ihren Portfolios hielten. Möglicherweise resultierende Refinanzierungs-, Ertrags-, und Liquiditätsvorteile für bevorteilte Banken könnten zu Wettbewerbsverzerrungen führen. Dieser Beitrag betrachtet deshalb die Wertpapierportfolios regionaler deutscher Banken, um den kausalen Effekt des SMP auf das Wettbewerbsverhalten zu identifizieren. Die empirischen Befunde belegen in der Tat eine statistisch nachweisbare Zunahme der lokalen Marktanteile jener regionalen Banken, welche Anleihen in ihren Portfolios hielten, die Teil des SMP waren. Während dieses Ergebnis somit einen Beleg für die Existenz unbeabsichtigter Nebenwirkungen unkonventioneller Geldpolitik darstellt, so ist auch festzuhalten dass diese Wettbewerbseffekte ausgesprochen klein sind. Somit ist zumindest für den regionalen Bankenmarkt in Deutschland keine nennenswerte Verwerfung aufgrund dieses Ankaufprogramms festzustellen.

Inside Asset Purchase Programs: The Effects of Unconventional Policy on Banking Competition
Michael Koetter, Natalia Podlich, Michael Wedow
ECB Working Paper Series,
No. 2017,
2017
Abstract
We test if unconventional monetary policy instruments influence the competitive conduct of banks. Between q2:2010 and q1:2012, the ECB absorbed Euro 218 billion worth of government securities from five EMU countries under the Securities Markets Programme (SMP). Using detailed security holdings data at the bank level, we show that banks exposed to this unexpected (loose) policy shock mildly gained local loan and deposit market shares. Shifts in market shares are driven by banks that increased SMP security holdings during the lifetime of the program and that hold the largest relative SMP portfolio shares. Holding other securities from periphery countries that were not part of the SMP amplifies the positive market share responses. Monopolistic rents approximated by Lerner indices are lower for SMP banks, suggesting a role of the SMP to re-distribute market power differentially, but not necessarily banking profits.
