Money and Inflation: The Role of Persistent Velocity Movements
Makram El-Shagi, Sebastian Giesen
Abstract
While the long run relation between money and inflation is well established, empirical evidence on the adjustment to the long run equilibrium is very heterogeneous. In the present paper we use a multivariate state space framework, that substantially expands the traditional vector error correction approach, to analyze the short run impact of money on prices. We contribute to the literature in three ways: First, we distinguish changes in velocity of money that are due to institutional developments and thus do not induce inflationary pressure, and changes that reflect transitory movements in money demand. This is achieved with a newly developed multivariate unobserved components decomposition. Second, we analyze whether the high volatility of the transmission from monetary pressure to inflation follows some structure, i.e., if the parameter regime can assumed to be constant. Finally, we use our model to illustrate the consequences of the monetary policy of the Fed that has been employed to mitigate the impact of the financial crisis, simulating different exit strategy scenarios.

Shocks at Large Banks and Banking Sector Distress: The Banking Granular Residual
S. Blank, Claudia M. Buch, Katja Neugebauer
Journal of Financial Stability,
Nr. 4,
2009
Abstract
Size matters in banking. In this paper, we explore whether shocks originating at large banks affect the probability of distress of smaller banks and thus the stability of the banking system. Our analysis proceeds in two steps. In a first step, we follow Gabaix and construct a measure of idiosyncratic shocks at large banks, the so-called Banking Granular Residual. This measure documents the importance of size effects for the German banking system. In a second step, we incorporate this measure of idiosyncratic shocks at large banks into an integrated stress-testing model for the German banking system following De Graeve et al. (2008). We find that positive shocks at large banks reduce the probability of distress of small banks.

Monetary Policy and Financial (In)stability: An Integrated Micro–Macro Approach
Ferre De Graeve, Thomas Kick, Michael Koetter
Journal of Financial Stability,
Nr. 3,
2008
Abstract
Evidence on central banks’ twin objective, monetary and financial stability, is scarce. We suggest an integrated micro–macro approach with two core virtues. First, we measure financial stability directly at the bank level as the probability of distress. Second, we integrate a microeconomic hazard model for bank distress and a standard macroeconomic model. The advantage of this approach is to incorporate micro information, to allow for non-linearities and to permit general feedback effects between financial distress and the real economy. We base the analysis on German bank and macro data between 1995 and 2004. Our results confirm the existence of a trade-off between monetary and financial stability. An unexpected tightening of monetary policy increases the probability of distress. This effect disappears when neglecting microeffects and non-linearities, underlining their importance. Distress responses are largest for small cooperative banks, weak distress events, and at times when capitalization is low. An important policy implication is that the separation of financial supervision and monetary policy requires close collaboration among members in the European System of Central Banks and national bank supervisors.

Evaluating the German (New Keynesian) Phillips Curve

Nr. 10,

Abstract
This paper evaluates the New Keynesian Phillips Curve (NKPC) and its hybrid
variant within a limited information framework for Germany. The main interest rests on the average frequency of price re-optimization of firms. We use the labor income share as the driving variable and consider a source of real rigidity by allowing for a fixed firm-specific capital stock. A GMM estimation strategy is employed as well as an identification robust method that is based upon the Anderson-Rubin statistic. We find out that the German Phillips Curve is purely forward looking. Moreover, our point estimates are consistent with the view that firms re-optimize prices every two to three quarters. While these estimates seem plausible from an economic point of view, the uncertainties around these estimates are very large and also consistent with perfect nominal price rigidity where firms never re-optimize prices. This analysis also offers some explanations why previous results for the German NKPC based on GMM differ considerably. First, standard GMM results are very sensitive to the way how orthogonality conditions are formulated. Additionally, model misspecifications may be left undetected by conventional J tests. Taken together, this analysis points out
the need for identification robust methods to get reliable estimates for the NKPC.

Why do we have an interbank money market?
Jürgen Wiemers, Ulrike Neyer
IWH Discussion Papers,
Nr. 182,
2003
Abstract
The interbank money market plays a key role in the execution of monetary policy. Hence, it is important to know the functioning of this market and the determinants of the interbank money market rate. In this paper, we develop an interbank money market model with a heterogeneous banking sector. We show that besides for balancing daily liquidity fluctuations banks participate in the interbank market because they have different marginal costs of obtaining funds from the central bank. In the euro area, which we refer to, these cost differences occur because banks have different marginal cost of collateral which they need to hold to obtain funds from the central bank. Banks with relatively low marginal costs act as intermediaries between the central bank and banks with relatively high marginal costs. The necessary positive spread between the interbank market rate and the central bank rate is determined by transaction costs and credit risk in the interbank market, total liquidity needs of the banking sector, costs of obtaining funds from the central bank, and the distribution of the latter across banks.

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.
