Abstract
Die Wirtschaftsrechnungen privater Haushalte wurden Ende der 90er Jahre mit dem Ziel einer verbesserten Integration neu gestaltet. Vor diesem Hintergrund wird untersucht, ob Haushaltsstichproben stärker als bisher zur Berechnung des gesamtwirtschaftlichen Privaten Verbrauchs geeignet sind. Dies muss zum jetzigen Stand verneint werden. Eine grundsätzliche Höhergewichtung der Haushaltsangaben im Prozess der Verbrauchsmessung wird für die Zukunft aber befürwortet. Weiterhin werden mikroökonomische Konsumanalysen auf Grundlage der Einkommens- und Verbrauchsstichproben 1993 und 1998 durchgeführt. Möglichkeiten und Grenzen solcher Analysen und Empfehlungen für eine Ausgestaltung derselben werden erarbeitet.

Diversifikation und regionale Wirtschafts- und Beschäftigungsentwicklung - Eine empirische Analyse für ausgewählte deutsche Gebiete
Peter Haug
Jahrbuch für Regionalwissenschaft,
No. 2,
2004
Abstract
Der Beitrag untersucht die Auswirkungen einer heterogenen Wirtschaftsstruktur auf die langfristige Beschäftigungsentwicklung einer Region. Es wird anhand eines einfachen mikroökonomischen Modells unter Unsicherheit illustriert, dass sowohl für private Haushalte als auch für Unternehmen die Ansiedlung in wirtschaftlich diversifizierteren Regionen aufgrund der damit verbundenen Versicherungsfunktion (Verringerung des Einkommensrisikos, Verringerung der Einstellungskosten im weitesten Sinne) für Arbeitgeber und Arbeitnehmer vorteilhaft sein kann. Die ökonomischen Schätzergebnisse für niedersächsische Kommunen deuten auf einen positiven Zusammenhang zwischen Diversifikation der lokalen Wirtschaft und der Beschäftigungssituation hin, und zwar sowohl auf der Ebene der aggregierten Arbeitskräftenachfrage einer Gemeinde, als auch für die Beschäftigung der meisten Wirtschaftszweige.

Evolving Structural Patterns in the Enlarging European Division of Labour: Sectoral and Branch Specialisation and the Potentials for Closing the Productivity Gap
Johannes Stephan
IWH-Sonderhefte,
No. 5,
2003
Abstract
This report summarises the results generated in empirical analysis within a larger EU 5th FP RTD-project on the determinants of productivity gaps between the current EU-15 and accession states in Central East Europe. The focus of research in this part of the project is on sectoral specialisation patterns emerging as a result of intensifying integration between the current EU and a selection of six newly acceding economies, namely Estonia, Poland, the Czech and Slovak Republics, Hungary and Slovenia. The research-leading question is concerned with the role played by the respective specialisation patterns for (i) the explanation of observed productivity gaps and for (ii) the projection of future potentials of productivity growth in Central East Europe.
For the aggregated level, analysis determines the share of national productivity gaps accountable to acceding countries’ particular sectoral patterns, and their role for aggregate productivity growth: in Poland, the Slovak Republic and Hungary, sectoral shares of national productivity gaps are considerable and might evolve into a ‘barrier’ to productivity catch-up.Moreover, past productivity growth was dominated by a downward adjustment in employment rather than structural change. With the industrial sector of manufacturing having been identified as the main source of national productivity gaps and growth, the subsequent analysis focuses on the role of industrial specialisation patterns and develops an empirical model to project future productivity growth potentials. Each chapter closes with some policy conclusions.

Why do we have an interbank money market?
Jürgen Wiemers, Ulrike Neyer
IWH Discussion Papers,
No. 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.

A macroeconometric model for the Euro economy
Christian Dreger
IWH Discussion Papers,
No. 181,
2003
Abstract
In this paper a structural macroeconometric model for the Eurozone is presented. In opposite to the multi country modelling approach, the model relies on aggregate data on the supra-national level. Due to nonstationarity, all equations are estimated in an error correction form. The cointegrating relations are derived jointly with the short-run dynamics, avoiding the finite sample bias of the two step Engle Granger procedure. The validity of the aggregated approach is confirmed by out-of-sample forecasts and two simulation exercises. In particular the implications of a lower economic recovery in the US and a shock in the nominal Euro area interest rate are discussed.

Does Transparency of Central Banks Produce Multiple Equilibria on Currency Markets?
Axel Lindner
IWH Discussion Papers,
No. 178,
2003
Abstract
A recent strand of literature (see Morris and Shin 2001) shows that multiple equilibria in models of markets for pegged currencies vanish if there is slightly diverse information between traders. It is known that this approach works only if there is not too precise common knowledge in the market. This has led to the conclusion that central banks should try to avoid making their information common knowledge. We present a model in which more transparency of the central bank means better private information, because each trader utilizes public information according to her own private information. Thus, transparency makes multiple equilibria less likely.
