Abstract
In this paper, a vector error correction model for Euro area money, prices, output, long-term interest rate and short-term interest rate with three identified cointegration relations is specified. It is shown that Euro area money and prices can be considered as variables that are integrated of order two or I(2), that is, they have to be differenced twice to become stationary. Accordingly, the relation between money, prices and other macroeconomic variables is analyzed in an econometric framework which is suited for the analysis of I(2)-variables. Monetary policy implications are derived from the estimated system.

The influence of Vertical Integration and Property Rights on Network Access Charges in the German Electricity Markets

Abstract
German Electricity markets were deregulated in the late nineties of the last century. In contrast to other European countries, the German government enacted negotiated third party access instead of installing a regulation authority. Network access charges for new competitors are based on contractual arrangements between energy producers and industrial consumers, which specify the calculation schemes for access charges. Local and regional suppliers are nevertheless able to set (monopolistic) charges at their own discretion, restricted only by the possibility of interference competition authorities. While some of those suppliers have been acquired by one of the four Transmission System Operators and become vertically integrated, the majority is still independent public utility companies. In this paper we analyse if there is evidence for different charging behaviour depending on the supplier’s economic independence or its level of vertical integration. Controlling for other coefficients as the so called structural features and related cost differences as well as the influence of competition law suits, multivariate estimations show significantly lower access charges than vertically separated suppliers, whereas incorporated network operators charge significantly higher charges compared to independent suppliers for at least one typical case.

Promotion of investment in East Germany - Results of an empirical study of effectiveness
Harald Lehmann, Andreas Stierwald
Wirtschaft im Wandel,
No. 5,

Abstract
In Germany considerable amounts of public funds are being spent on business development programs. In order to do so economic reasoning is needed. In particular the programs for supporting investment lack microeconometric empirical evaluation. To close this gap the special program „Gemeinschaftsaufgabe zur Verbesserung der regionalen Wirtschaftsstruktur“ (GA) is exemplarily analyzed. This program is intended to strengthen the capital stock of the East German economy, so firms of the East German manufacturing industries will be studied. A comparison of the two fundamental methods for microeconometric evaluation shall demonstrate the general problems in analyzing the effectiveness of development programs. The matching estimator provides more stable results then a sample selectivity model. The results suggest that the GA generates considerable extra investment activities.

Evaluation of Further Training Programmes with an Optimal Matching Algorithm

IWH Discussion Papers,
No. 188,
2004
Abstract
This study evaluates the effects of further training on the individual unemployment duration of different groups of persons representing individual characteristics and some aspects of the economic environment. The Micro Census Saxony enables us to include additional information about a person's employment history to eliminate the bias resulting from unobservable characteristics and to avoid Ashenfelter's Dip. In order to solve the sample selection problem we employ an optimal full matching assignment, the Hungarian algorithm. The impact of participation in further training is evaluated by comparing the unemployment duration between participants and non-participants using the Kaplan-Meier-estimator. Overall, we find empirical evidence that participation in further training programmes results in even longer unemployment duration.

Effects of the promotion of investment in East Germany
Joachim Ragnitz
IWH Discussion Papers,
No. 186,
2003
Abstract
Investment in East Germany is heavily subsidized. Econometric estimates based on a treatment approach show that the level of investment is significantly higher in firms being supported by state aid. Nevertheless, capital productivity is lower in East Germany, indicating a misallocation of capital. Additionally, there are negative effects in West Germany due to negative crowding-out effects. Therefore state aid in East Germany should be reduced in the medium run.

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.

New fields of application for the input-output analysis in Germany - Contributions to the Input-Output Workshop 2002 in Halle
IWH-Sonderhefte,
No. 4,
2003
Abstract
Centrepiece of the discussion is the employment-orientated evaluation of large scale Investments. The analysis is based on the static open Input-Output-Model. For both, industrial as well as construction projects, the direct and indirect employment effects at the construction as well as the utilization stage are being estimated and combined with the multiplier effect caused by the created income. Finally, the discussion concludes by evaluating the employment effects of the necessary reconstruction efforts after the flood in summer 2002.
