Abstract
We propose a unified identification scheme to identify monetary shocks and track their propagation through the economy. We combine three approaches dealing with the consequences of monetary shocks. First, we adjust a state space version of the P-star type model employing money overhang as the driving force of inflation. Second, we identify the contemporaneous impact of monetary policy shocks by applying a sign restriction identification scheme to the reduced form given by the state space signal equations. Third, to ensure that our results are not distorted by the measurement error exhibited by the official monetary data, we employ the Divisia M4 monetary aggregate provided by the Center for Financial Stability. Our approach overcomes one of the major difficulties of previous models by using a data-driven identification of equilibrium velocity. Thus, we are able to show that a P-star model can fit U.S. data and money did indeed matter in the United States.

Musterknabe Osteuropa: Subventionskontrolle und staatliche Beihilfen
Jens Hölscher
Wirtschaftsdienst,
Nr. 5,
2014
Abstract
Am 1.5.2004 sind zehn neue Mitgliedstaaten, vor allem Transformationsländer, in die EU aufgenommen worden. Drei Jahre später, am 1.1.2007, kamen Bulgarien und Rumänien hinzu. Während deutsche Unternehmer zunächst die zusätzliche Konkurrenz fürchteten, bewerten sie die Auswirkungen der Osterweiterung inzwischen positiv. Die neuen Mitgliedstaaten haben von ihrem Beitritt grundsätzlich profitiert, sogar in Hinblick auf die Beihilferegelungen konnten sie den strengen Anforderungen der EU entsprechen. Allerdings haben sich flexible Wechselkurse in der Krise für die Länder außerhalb des Euroraums als Vorteil erwiesen. Zudem leiden Rumänien und Bulgarien unter der Instabilität ihrer politischen Systeme.

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.

Government Banking in Russia: Magnitude and New Features
Andrei Vernikov
IWH Discussion Papers,
Nr. 13,
2011
Abstract
State-controlled banks are currently at the core of financial intermediation in Russia. This paper aims to assess the magnitude of government banking, and to reveal some of its special features and arrangements. We distinguish between directly and indirectly state-controlled banks and construct a set of bank-level statistical data covering the period between 2000 and 2011. By January 2011 the market share of state-controlled banks reached almost 54 percent of all bank assets, putting Russia in the same league with China and India and widening the gap from typical European emerging markets. We show that direct state ownership is gradually substituted by indirect ownership and control. It tends to be organized in corporate pyramids that dilute public property, take control away from government bodies, and underpin managerial opportunism. Statecontrolled
banks blur the borderline between commercial banking and development
banking. Dominance of public banks has a bearing on empirical studies whose results might suggest state-owned banks’ greater (or lesser) efficiency or competitiveness compared to other forms of ownership. We tend to interpret such results as influenced by the choice of indicator, period of observations, sample selection, etc., in the absence of an equal playing field for all groups of players. We suggest that the government’s planned retreat from the banking sector will involve non-core assets mainly, whereas control over core institutions will just become more subtle.

A Study of the Competitiveness of Regions based on a Cluster Analysis: The Example of East Germany
Franz Kronthaler
IWH Discussion Papers,
Nr. 179,
2003
Abstract
This paper examines whether some East German regions have already achieved the same economic capability as the regions in West Germany, so that they are on a competitive basis with the West German regions and are able to reach the same economic level in the long run. If this is not the case, it is important to know more about the reasons for the economic weakness of the East German regions twelve years after unification.
The study is based on a cluster analysis. Criteria for the cluster formation are several economic indicators, which provide information about the economic capability of regions. The choice of the indicators is based on a review of results of the theoretical and empirical literature on the new growth theory and new economic geography.
The results show that most of the East German regions have not yet reached the economic capability and competitiveness of their West German counterparts so that they - from the viewpoint of the new growth theory and the new economic geography - are not in the position to reach the same economic level. According to these theories economic disadvantages are most notably the consequences of less technical progress, a lack of entrepreneurship and fewer business concentration. Under these points it is especially noteworthy that young well educated people leave these East German regions so that human capital might will turn into a bottle-neck in the near future. Only a few regions in East Germany - those with important agglomerations - are comparable to West German regions that are characterised by average capability and competitiveness, but not to those with above average economic capability and competitiveness. Even those more advanced East German regions still suffer from a slower technical progress.
There are important policy implications based on these results: regional policy in East Germany was not able to assist raising all regions to a sufficient level of competitiveness. It may be more effective to concentrate the regional policy efforts on a selection of important agglomerations. This has also strong implications for the EU regional policy assuming that the accession countries will have similar problems in catching up to the economic level of the EU as have the East German regions.

EU Eastern Enlargement and Structural Change: Specialization Patterns in Accession Countries and Economic Dynamics in the Single Market

Abstract
Der Beitrag untersucht Kernfragen des Strukturwandels und der Spezialisierungsmuster in den Volkswirtschaften der erweiterten Europäischen Union. In allen Transformationsländern wurden, gemessen an Beschäftigung und Produktivität, Verschiebungen von landwirtschaftlichen und industriellen Sektor hin zum Dienstleistungssektor beobachtet – z.T. mit späteren Reindustrialisierungsphasen. Während einige Ländern, insbesondere Tschechien, Ungarn, die Slowakei, Polen, Estland und Slowenien ihre Produktivität in mittleren technologieintensiven Bereichen verbessert haben und die Technologieleiter aufwärts steigen können, bleiben andere bei einer Struktur mit vielen arbeitsintensiven Zweigen. Im Kontext der EU-Erweiterung sind handelsschaffende Effekte – insbesondere in Verbindung mit einem Anstieg des intra-industriellen Handels – und verstärkte Direktinvestitionen zu erwarten. Alle beteiligten Länder müssen sich gemäß ihren komparativen Vorteilen spezialisieren, allerdings können staatliche F&E-Ausgaben sowie Bildungsanstrengungen auf die Entwicklung solcher Vorteile Einfluss nehmen. Die Gerschenkron-Hypothese postuliert für die Beitrittsländer einen „Vorteil der Rückständigkeit“. Da diese Länder in der ersten Transformationsphase niedrige F&E-Intensitäten in der ersten Transformationsphase aufweisen, ist die Modernisierung des Bildungs- und Forschungssektors wesentlich. Für die EU-15 als Ganzes wird ein Erweiterungsgewinn erwartet, aber die Vorteile werden sich über die Länder hinweg unterschiedlich darstellen, da die ökonomische Geografie eine Rolle spielt. Österreich, Deutschland, die skandinavischen Länder, die Niederlande, Italien und Frankreich werden voraussichtlich stärker von der Erweiterung profitieren als die anderen Mitglieder der EU-15. Deutschland und Österreich spielen zusätzlich eine wichtige Rolle als Ursprungsländer für Direktinvestitionen. Es gibt noch einen erheblichen Forschungsbedarf bezüglich Ausmaß und Richtung des Strukturwandels.
