A First Look on the New Halle Economic Projection Model
Sebastian Giesen, Oliver Holtemöller, Juliane Scharff, Rolf Scheufele
Abstract
In this paper we develop a small 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 recently published by the International
Monetary Fund (global projection model). Our main contribution is that we model the Euro area countries separately. In this version we consider Germany and France, which represent together about 50 percent of Euro area GDP. The model allows for country specific heterogeneity in the sense that we capture different adjustment patterns to economic shocks. The model is estimated using Bayesian techniques. Out-of-sample and pseudo out-of-sample forecasts are presented.

A Game Theoretic Analysis of the Conditions of Knowledge Transfer by New Employees in Companies
Sidonia vonLedebur
IWH Discussion Papers,
Nr. 3,
2006
Abstract
The availability of knowledge is an essential factor for an economy in global competition. Companies realise innovations by creating and implementing new knowledge. Sources of innovative ideas are partners in the production network but also new employees coming from another company or academia. Based on a model by HECKATHORN (1996) the conditions of efficient knowledge transfer in a team are analysed. Offering knowledge to a colleague can not be controlled directly by the company due to information asymmetries. Thus the management has to provide incentives which motivate the employees to act in favour of the company by providing their knowledge to the rest of the team and likewise to learn from colleagues. The game theoretic analysis aims at investigating how to arrange these incentives efficiently. Several factors are relevant, especially the individual costs of participating in the transfer. These consist mainly of the existing absorptive capacity and the working atmosphere. The model is a 2x2 game but is at least partly generalised on more players. The relevance of the adequate team size is shown: more developers may increase the total profit of an innovation
(before paying the involved people) but when additional wages are paid to each person a greater team decreases the remaining company profit. A further result is
that depending on the cost structure perfect knowledge transfer is not always best for the profit of the company. These formal results are consistent with empirical studies to the absorptive capacity and the working atmosphere.

The unemployment-growth relationship in transition countries
Hubert Gabrisch, Herbert Buscher
IWH Discussion Papers,
Nr. 5,
2005
Abstract
Does the disappointingly high unemployment in Central and East European countries reflect non-completed adjustment to institutional shocks from transition to a market economy, or is it the result of high labour market rigidities, or rather a syndrome of too weak aggregate demand and output? In the case of transitional causes, unemployment is expected to decline over time. Otherwise, it would pose a challenge to the European Union, particular in case of accession countries, for it jeopardizes the ambitious integration plans of, and may trigger excessive migration to the Union. In order to find out which hypothesis holds 15 years after transition has started, we analyze the unemploymentgrowth dynamics in the eight new member countries from Central-Eastern Europe. The study is based on country and panel regressions with instrument variables (TSLS). The results suggest to declare the transition of labour markets as completed; unemployment responds to output and not to a changing institutional environment for job creation. The regression coefficients report a high trend rate of productivity and a high unemployment intensity of output growth since 1998. The conclusion is that labour market rigidities do not to play an important role in explaining high unemployment rates. Rather, GDP growth is dominated by productivity progress, while the employment relevant component of aggregate demand is too low to reduce substantially the high level of unemployment.

Financial Openness and Business Cycle Volatility
Claudia M. Buch, Jörg Döpke, C. Pierdzioch
Journal of International Money and Finance,
Nr. 5,
2005
Abstract
This paper discusses whether the integration of international financial markets affects business cycle volatility. In the framework of a new open economy macro-model, we show that the link between financial openness and business cycle volatility depends on the nature of the underlying shock. Empirical evidence supports this conclusion. Our results also show that the link between business cycle volatility and financial openness has not been stable over time.

Economic Opening Up and Growth in Russia: Finance, Trade, Market Institutions, and Energy,
2004
Abstract
The transition to a market economy in the former CMEA area is more than a decade old and one can clearly distinguish a group of relatively fast growing countries — including Estonia, Poland, the Czech Republic, Hungary and Slovenia — and a majority of slowly growing economies, including Russia and the Ukraine. Initial problems of transition were natural in the sense that systemic transition to a market economy has effectively destroyed part of the existing capital stock that was no longer profitable under the new relative prices imported from world markets; and there was a transitory inflationary push as low state-administered prices were replaced by higher market equilibrium prices. Indeed, systemic transformation in eastern Europe and the former Soviet Union have brought serious transitory inflation problems and a massive transition recession; negative growth rates have continued over many years in some countries, including Russia and the Ukraine, where output growth was negative throughout the 1990s (except for Russia, which recorded slight growth in 1997). For political and economic reasons the economic performance of Russia is of particular relevance for the success of the overall transition process. If Russia would face stagnation and instability, this would undermine political and economic stability in the whole of Europe and prospects for integrating Russia into the world economy.

Stellung und Perspektiven Sachsen-Anhalts in der New Economy
Martin T. W. Rosenfeld, Joachim Ragnitz, Rupert Kawka, Walter Komar
IWH-Sonderhefte,
Nr. 6,
2003
Abstract
Der technische Fortschritt zählt zu den zentralen Determinanten des wirtschaftlichen Wachstums. Regionen, in denen viel Forschung und Entwicklung betrieben wird, haben daher eine bessere Ausgangsposition im Standortwettbewerb als solche, wo dies in nur geringerem Maß geschieht. Eine besondere Hoffnung gilt dabei den Hochtechnologiebranchen und nicht zuletzt dem hier untersuchten Informations- und Kommunikationssektor sowie dem Biotechnologiesektor. Diese beiden Bereiche bilden einen wesentlichen Teilbestand der so genannten New Economy. Die Vergangenheit hat gezeigt, dass die New Economy nicht von Krisen verschont bleibt, und so ist ein realistischeres Bild von den Chancen, die diese Hochtechnologien bieten können, entstanden. Dennoch besteht die berechtigte Hoffnung, dass die beiden genannten Branchen weiterhin einen weitreichenden Einfluss auch auf andere Wirtschaftssektoren ausüben, indem sie so genannte Schlüssel- oder Querschnittstechnologien entwickeln und anbieten.

Standortbedingungen für die New Economy in strukturschwachen Regionen: Das Beispiel Sachsen-Anhalt
Walter Komar
Wirtschaft im Wandel,
Nr. 9,
2003
Abstract
Der Artikel präsentiert Befunde einer Analyse der Standortbedingungen für die New Economy in Sachsen-Anhalt, d. h. für die Sektoren der modernen Biotechnologie und der modernen Informationstechnologie. Hierfür wurden die Standortbedingungen zwischen Sachsen-Anhalt und der Raumordungsregion (ROR) München verglichen, die zu den fortgeschrittenen Regionen in diesen Branchen in Deutschland zählt. Erwartungsgemäß schneidet die ROR München bei den meisten Feldern besser ab. Die Analyse zeigt aber auch, dass noch nicht so fortgeschrittene Regionen auch Entwicklungschancen in neuen Branchen haben. Dazu müssen diese Regionen ihre Potentiale und Standortvorteile noch besser nutzen sowie noch vorhandene Standortdefizite abbauen.

Macroeconomic Modelling of the German Economy in the Framework of Euroland
Rüdiger Pohl, Heinz P. Galler
Schriften des IWH,
Nr. 11,
2002
Abstract
An attempt to develop a new macroeconometric model for Germany is confronted with several questions that range from the general rationality of such an approach to specific problems of an appropriate model structure. One important aspect of this discussion is the introduction of the Euro as a common currency of the European monetary union. This institutional change may result in structural breaks due to changing behavior of economic agents. In addition, the definition of the spatial unit that is appropriate for modelling becomes a problem. Additional problems come from the introduction of the European Single Market and the increasing international economic integration not only within the European union but also beyond its borders. And in the case of Germany, the unification of the West and the East demand special attention. Last but not least, the harmonization of national accounting for the member states of the European Union has to be dealt with. Thus, the introduction of the Euro as a common currency is just one problem besides others that must be addressed.
