A macroeconometric model for the Euro economy
Christian Dreger
IWH Discussion Papers,
Nr. 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.

Macroeconomic Modelling of the German Economy in the Framework of Euroland

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.

A Glimpse on Sectoral Convergence of Productivity Levels
Gerald Müller
IWH Discussion Papers,
Nr. 133,
2001
Abstract
This paper examines the presence of sectoral convergence of labor productivity between 14 OECD countries. Using the OECD International Sectoral Data Base (ISDB), the paper looks at the developments within 12 distinct sectors during the period 1970-1995. The change of the coefficients of variance suggests that there is strong sectoral convergence within most service sectors while the evidence of convergence for Manufacturing as well as for Communication is rather weak. These findings are in line with most studies undertaken on this subject so far. It is concluded that economic theories at hand to explain growth and convergence (or divergence respectively) are of different importance for the sectors concerned. While models of the New Growth Theory seemed to be useful to explain growth mechanisms within Manufacturing and Communication, traditional models seemed to apply to most other sectors.
