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,
Nr. 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.

Monetary Policy under the Microscope: Intra-bank Transmission of Asset Purchase Programs of the ECB
L. Cycon, Michael Koetter
IWH Discussion Papers,
Nr. 9,
2015
Abstract
With a unique loan portfolio maintained by a top-20 universal bank in Germany, this study tests whether unconventional monetary policy by the European Central Bank (ECB) reduced corporate borrowing costs. We decompose corporate lending rates into refinancing costs, as determined by money markets, and markups that the bank is able to charge its customers in regional markets. This decomposition reveals how banks transmit monetary policy within their organizations. To identify policy effects on loan rate components, we exploit the co-existence of eurozone-wide security purchase programs and regional fiscal policies at the district level. ECB purchase programs reduced refinancing costs significantly, even in an economy not specifically targeted for sovereign debt stress relief, but not loan rates themselves. However, asset purchases mitigated those loan price hikes due to additional credit demand stimulated by regional tax policy and enabled the bank to realize larger economic margins.

Financial Integration, Housing, and Economic Volatility
Elena Loutskina, Philip E. Strahan
Journal of Financial Economics,
Nr. 1,
2015
Abstract
The Great Recession illustrates the sensitivity of the economy to housing. This paper shows that financial integration, fostered by securitization and nationwide branching, amplified the positive effect of housing price shocks on the economy during the 1994–2006 period. We exploit variation in credit supply subsidies across local markets from government-sponsored enterprises to measure housing price changes unrelated to fundamentals. Using this instrument, we find that house price shocks spur economic growth. The effect is larger in localities more financially integrated, through both secondary loan market and bank branch networks. Financial integration thus raised the effect of collateral shocks on local economies, increasing economic volatility.

The Synchronization of Wage Dynamics across EMU Members: A Test of the Endogeneity Hypothesis
Herbert S. Buscher, Hubert Gabrisch
Empirica,
Nr. 3,
2012
Abstract
We test the hypothesis of an endogenous currency area for the labor market of the Euro area: has the introduction of a common currency caused wage dynamics to become more synchronized and to be able to cushion for asymmetric shocks? Trade intensity, sector specialization and financial integration are tested for being the driving forces for the endogenous synchronization of wage dynamics. We use regression techniques with instrument variables, and find evidence of persistent asymmetries in nominal wage formation, despite a single currency and monetary policy. We explain the result with more specialization following financial integration, and with still existing differences in wage formation and labor market institutions. We conclude that the euro zone is not endogenous with respect to wage formation. Rather, there are incentives for beggar-thy-neighbor policies in the Euro area.

Monetary Policy in a World Where Money (Also) Matters
Makram El-Shagi, Sebastian Giesen
IWH Discussion Papers,
Nr. 6,
2012
Abstract
While the long-run relation between money and inflation as predicted by the quantity theory is well established, empirical studies of the short-run adjustment process have been inconclusive at best. The literature regarding the validity of the quantity theory within a given economy is mixed. Previous research has found support for quantity theory within a given economy by combining the P-Star, the structural VAR and the monetary aggregation literature. However, these models lack precise modelling of the short-run dynamics by ignoring interest rates as the main policy instrument. Contrarily, most New Keynesian approaches, while excellently modeling the short-run dynamics transmitted through interest rates, ignore the role of money and thus the potential mid-and long-run effects of monetary policy. We propose a parsimonious and fairly unrestrictive econometric model that allows a detailed look into the dynamics of a monetary policy shock by accounting for changes in economic equilibria, such as potential output and money demand, in a framework that allows for both monetarist and New Keynesian transmission mechanisms, while also considering the Barnett critique. While we confirm most New Keynesian findings concerning the short-run dynamics, we also find strong evidence for a substantial role of the quantity of money for price movements.

Optimum Currency Areas in Emerging Market Regions: Evidence Based on the Symmetry of Economic Shocks
Stefan Eichler, Alexander Karmann
Open Economies Review,
Nr. 5,
2011
Abstract
This paper examines which emerging market regions form optimum currency areas (OCAs) by assessing the symmetry of macroeconomic shocks. We extend the output-prices-VAR framework by adding net exports and the real effective exchange rate as endogenous variables. Based on theoretical considerations, we derive which shocks affect these variables in the long run: shocks to labor productivity, foreign trade, labor supply, and money supply. The considered economies of Central and Eastern Europe, the Commonwealth of Independent States, East and Southeast Asia, and South Asia, exhibit large enough shock symmetry to form a currency union; the economies of Africa, Latin America, and the Middle East do not.

Industrial Associations as a Channel of Business-Government Interactions in an Imperfect Institutional Environment: The Russian Case
A. Yakovlev, A. Govorun
IWH Discussion Papers,
Nr. 16,
2011
Abstract
International lessons from emerging economies suggest that business associations may provide an effective channel of communication between the government and the private sector. This function of business associations may become still more important in transition economies, where old mechanisms for coordinating enterprise activities have been destroyed, while the new ones have not been established yet. In this context, Russian experience is a matter of interest, because for a long time, Russia was regarded as a striking example of state failures and market failures. Consequently, the key point of our study was a description of the role and place of business associations in the presentday
Russian economy and their interaction with member companies and bodies of state
administration. Relying on the survey data of 957 manufacturing firms conducted in
2009, we found that business associations are more frequently joined by larger companies, firms located in regional capital cities, and firms active in investment and innovation. By contrast, business associations tend to be less frequently joined by business groups’ subsidiaries and firms that were non-responsive about their respective ownership structures. Our regression analysis has also confirmed that business associations are a component of what Frye (2002) calls an “elite exchange”– although only on regional and local levels. These “exchanges” imply that members of business associations, on the one hand, more actively assist regional and local authorities in social development of their regions, and on the other hand more often receive support from authorities. However, this effect is insignificant in terms of support from the federal government. In general, our results allow us to believe that at present, business associations (especially the
industry-wide and “leading” ones) consolidate the most active, advanced companies and act as collective representatives of their interests. For this reason, business associations can be regarded as interface units between the authorities and businesses and as a possible instrument for promotion of economic development.

What Might Central Banks Lose or Gain in Case of Euro Adoption – A GARCH-Analysis of Money Market Rates for Sweden, Denmark and the UK
Herbert S. Buscher, Hubert Gabrisch
IWH Discussion Papers,
Nr. 9,
2011
Abstract
This study deals with the question whether the central banks of Sweden, Denmark and the UK can really influence short-term money markets and thus, would lose this influence in case of Euro adoption. We use a GARCH-M-GED model with daily money market rates. The model reveals the co-movement between the Euribor and the shortterm interest rates in these three countries. A high degree of co-movement might be seen as an argument for a weak impact of the central bank on its money markets. But this argument might only hold for tranquil times. Our approach reveals, in addition, whether there is a specific reaction of the money markets in turbulent times. Our finding is that the policy of the European Central Bank (ECB) has indeed a significant impact on the three money market rates, and there is no specific benefit for these countries to stay outside the Euro area. However, the GARCH-M-GED model further reveals risk divergence and unstable volatilities of risk in the case of adverse monetary shocks to the economy for Sweden and Denmark, compared to the Euro area. We conclude that the danger of adverse monetary developments cannot be addressed by a common monetary
policy for these both countries, and this can be seen as an argument to stay outside the Euro area.
