Monetary Policy in a World Where Money (Also) Matters

No. 6,

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.

Delineation of City Regions Based on Commuting Interrelations: The Example of Large Cities in Germany
Albrecht Kauffmann
IWH Discussion Papers,
No. 4,
2012
Abstract
The comparison of cities with regard to their economic or demographic development may yield misleading results, if solely the cities in their administrative borders are the object of consideration. Frequently, historical borders of cities neither conform to the contemporary settlement structures, nor do they consider the mutual dependencies between cities and parts of their hinterland. Therefore, it is often claimed to use city regions as objects of comparison or for the sake of urban planning. Commonly, the delineation of functional regions is based on commuting flows from the municipalities in the hinterland of the core cities directed to the cores. A municipality is regarded as belonging to a certain city region if the share of out-commuters from this municipality to the respective core in the total mass of those employees who reside in that municipality is the largest one, and if this share exceeds a certain threshold value. However, commuting flows in the opposite direction are not considered. The method presented here delineates city regions on the base of bidirectional commuting flows. Hereby, various modifications regarding the characteristics of the employment base, the possibility of overlaps of regions, the formation of polycentric city regions, and of the minimum threshold value of mutual connectivity are applied to the sample of 81 German cities with more than 100 000 inhabitants. Finally, the effects of different kinds of regionalisation on the coefficients of regional specialisation of these cities and city regions are demonstrated.

What Drives Banking Sector Fragility in the Eurozone? Evidence from Stock Market Data
Stefan Eichler, Karol Sobanski
Journal of Common Market Studies,
No. 4,
2012
Abstract
This article explores the determinants of banking sector fragility in the eurozone. For this purpose, a stock-market-based banking sector fragility indicator is calculated for eight member countries from 1999 to 2009 using the Merton model (1974). Using a panel framework, it is found that the macroeconomic environment, the structure of the banking sector and the intensity of banking regulation all have an effect on banking sector fragility in the eurozone.

Vierteljährliche Konjunkturberichterstattung für das Land Sachsen-Anhalt – Die gesamtwirtschaftliche Lage im 4. Quartal 2011 –

Einzelveröffentlichungen,
No. 4,

Abstract
Das Bruttoinlandsprodukt in Sachsen-Anhalt hat im Schlussquartal des vergangenen Jahres nach dem starken Anstieg im dritten Quartal in etwa stagniert. Die Industrie erlitt vor dem Hintergrund der konjunkturellen Eintrübung in der Welt und der Risiken im Zusammenhang mit der Schuldenkrise Umsatzverluste. So haben rückläufige Ausfuhren, zum Teil aber auch eingeschränkte private Konsumausgaben und zurückhaltende Investitionen der Unternehmen zu einer Kontraktion der Industrieproduktion geführt. Im Dienstleistungsbereich blieb die Bruttowertschöpfung unter diesem Einfluss nur etwa auf dem Niveau des Vorquartals. Das Baugewerbe legte dagegen aufgrund der milden Witterung und anhaltender Baunachfrage am Jahresende zu; sein deutlicher Zuwachs reichte, um die Rückgänge in der Industrie in etwa auszugleichen. Sachsen-Anhalt bleibt damit im vierten Quartal 2011 hinter der Entwicklung in Deutschland (0,4%) zurück. Allerdings war die konjunkturelle Grundtendenz in Sachsen-Anhalt im Vorquartal wegen der Aufholeffekte nach dem technisch bedingten Ausfall in der Mineralölverarbeitung im zweiten Quartal überzeichnet. Eine schwächere Entwicklung war somit in der Industrie zu erwarten gewesen.

The Halle Economic Projection Model

Economic Modelling,
No. 4,
2012
Abstract
In this paper we develop an open economy model explaining the joint determination of output, inflation, interest rates, unemployment and the exchange rate in a multi-country framework. Our model -- the Halle Economic Projection Model (HEPM) -- is closely related to studies published by Carabenciov et al. Our main contribution is that we model the Euro area countries separately. In doing so, we consider Germany, France, and Italy which represent together about 70 percent of Euro area GDP. The model combines core equations of the New-Keynesian standard DSGE model with empirically useful ad-hoc equations. We estimate this model using Bayesian techniques and evaluate the forecasting properties. Additionally, we provide an impulse response analysis and a historical shock decomposition.

Central Bank, Trade Unions, and Reputation – Is there Room for an Expansionist Manoeuvre in the European Union?

A. Heise (ed.), Market Constellation Research: A Modern Governance Approach to Macroeconomic Policy. Institutionelle und Sozial-Ökonomie, Bd. 19,
2011
Abstract
The objective of this reader is manifold: On the one hand, it intends to establish a new perspective at the policy level named 'market constellations': institutionally embedded systems of macroeconomic governance which are able to explain differences in growth and employment developments. At the polity level, the question raised is whether or not market constellations can be governed and, thus, whether institutions can be created which will provide the incentives necessary for favourable market constellations.

Protect and Survive? Did Capital Controls Help Shield Emerging Markets from the Crisis?
Makram El-Shagi
Economics Bulletin,
No. 1,
2012
Abstract
Using a new dataset on capital market regulation, we analyze whether capital controls helped protect emerging markets from the real economic consequences of the 2009 financial and economic crisis. The impact of the crisis is measured by the 2009 forecast error of a panel state space model, which analyzes the business cycle dynamics of 63 middle-income countries. We find that neither capital controls in general nor controls that were specifically targeted to derivatives (that played a crucial role during the crisis) helped shield economies. However, banking regulation that limits the exposure of banks to global risks has been highly successful.

A Macroeconomist’s View on EU Governance Reform: Why and How to Establish Policy Coordination?
Hubert Gabrisch
Economic Annals,
No. 191,
2011
Abstract
This paper discusses the need for macroeconomic policy coordination in the E(M)U. Coordination of national policies with cross-border effects does not exist at the macroeconomic level, although requested by the EU Treaty. The need for coordination stems from current account imbalances, which origin in market-induced capital flows, destabilizing the real exchange rates between low and high wage countries. The recent attempts of the Commission and the European Council to reform E(M)U governance do not address this problem and thus remain incapable to protect against future instability.

Vierteljährliche Konjunkturberichterstattung für das Land Sachsen-Anhalt – Die gesamtwirtschaftliche Lage im 3. Quartal 2011 –
Udo Ludwig, Brigitte Loose, Franziska Exß
Einzelveröffentlichungen,
No. 3,
2011
Abstract
Nach der konjunkturellen Delle im zweiten Quartal hat die wirtschaftliche Aktivität in Sachsen- Anhalt in den folgenden Monaten kräftig zugelegt. Die Industrie holte die zuvor erlittenen Verluste fast auf, auch das Baugewerbe und der Handel drehten in den Plusbereich. Das Bruttoinlandsprodukt ist im dritten Vierteljahr gegenüber dem Vorquartal um 1,1% kräftig gestiegen. Das war deutlich mehr als im Durchschnitt für Deutschland (0,4%) und für die neuen Bundesländer insgesamt (0,6%). Allerdings wird die überdurchschnittliche Stärke des Anstiegs von der niedrigen Startposition im zweiten Quartal geprägt, so dass die konjunkturelle Grundtendenz überzeichnet sein dürfte. So kam es im umsatzstärksten Industriezweig, der Mineralölverarbeitung, zu einem Aufholeffekt nach dem technisch bedingten Ausfall einer Monatsproduktion im zweiten Quartal. Dies spiegelt sich auch in den Leistungen von Handel und Verkehr wider.
