IWH Discussion Papers,
No. 9,
2008
Abstract
This paper describes the IWH macroeconometric model, a quarterly structural model for the German Economy. It focuses on the specification and estimation on supply-side aspects of the model. This approach guarantees a theoretical derived long-run model equilibrium. It combines short-run forecasting requirements with a long-run theoretical foundation. For some macroeconomic aggregates short- and long-run effects of supply- and demand shocks are illustrated. Additionally, effects of external shocks are investigated through model simulations to illustrate aggregate model characteristics.

FDI and Domestic Investment: An Industry-level View
Claudia M. Buch
CEPR. Discussion Paper No. 6464,
2007
Abstract
Previous empirical work on the link between domestic and foreign investment provides mixed results which partly depend on the level of aggregation of the data. We argue that the aggregated home country implications of foreign direct investment (FDI) cannot be gauged using firm-level data. Aggregated data, in turn, miss channels through which domestic and foreign activities interact. Instead, industry-level data provide useful information on the link between domestic and foreign investment. We theoretically show that the effects of FDI on the domestic capital stock depend on the structure of industries and the relative importance of domestic and multinational firms. Our model allows distinguishing intra-sector competition from inter-sector linkage effects. We test the model using data on German FDI. Using panel cointegration methods, we find evidence for a positive long-run impact of FDI on the domestic capital stock and on the stock of inward FDI. Effects of FDI on the domestic capital stock are driven mainly by intra-sector effects. For inward FDI, inter-sector linkages matter as well.

Spillover Effects of Spatial Growth Poles - a Reconciliation of Conflicting Policy Targets?
Alexander Kubis, Mirko Titze, Joachim Ragnitz
IWH Discussion Papers,
No. 8,
2007
Abstract
Regional economic policy faces the challenge of two competing policy goals - reducing regional economic disparities vs. promoting economic growth. The allocation of public funds has to weigh these goals particularly under the restriction of scarce financial re- sources. If, however, some region turns out to be a regional growth pole with positive spillovers to its disadvantaged periphery, regional policies could be designed to recon- cile the conflicting targets. In this case, peripheral regions could indirectly participate in the economic development of their growing cores. We start our investigation by defining and identifying such growth poles among German regions on the NUTS 3 administrative level based on spatial and sectoral effects. Using cluster analysis, we determine significant characteristics for the general identification of growth poles. Patterns in the sectoral change are identified by means of the change in the employment. Finally, we analyze whether and to what extent these growth poles ex- ert spatial spillover effects on neighbouring regions and thus mitigate contradictory in- terests in regional public policy. For this purpose, we apply a Spatial-Cross-Regressive- Model (SCR-Model) including the change in the secondary sector which allows to con- sider functional economic relations on the administrative level chosen (NUTS 3).

Institutionelle Defizite und wachsende Spannungen in der Euro-Zone
Hubert Gabrisch
Wirtschaft im Wandel,
No. 7,
2007
Abstract
The introduction of the Euro was certainly a success. Nevertheless, behind this success one may find some increasing asymmetries and imbalances across member countries, which may undermine the stability of the common currency in the long run. Tensions include the paralysis of fiscal policy, increasing divergence in per capita income, a high volatility of real state prices, and diverging unit labour cost developments. The given forms of macroeconomic coordination seem not to be appropriate to mitigate the problems. Obviously, countries can compete with wage policy only after currencies and their exchange rates were abolished, and the use of fiscal policy has been restricted. In particular, Germany and Austria were successful in competitive wage policy, while countries like Spain, Greece, Portugal, Italy, and also France did not yet use the competitiveness channel. Germany was able to reduce its unit labour costs more than other countries by labour market reforms and higher indirect taxes in replacing social taxes. However, the advantage may proof to be temporary only, for other countries will be forced to follow the German example. Given an ECB inflation target of 2 %, more competitive wage policy in the Euro area might jeopardize the stability of the currency through deflation and higher unemployment. It does not wonder that the discussion on other and new forms of macroeconomic coordination revived recently. This debate does not only include the introduction of a central EU budget with anti-cyclical effects, but also forms of direct and indirect coordination of national wage policies. In any case, it would be useful to oblige national wage policies to obey the common interest of the Union.

Microeconometric Evaluation of Selected ESF-funded ALMP-Programmes
Eva Reinowski, Birgit Schultz
IWH Discussion Papers,
No. 17,
2006
Abstract
The study evaluates different ESF-funded labour market programmes by comparing the labour market status at different points in time after the treatment. In order to solve the selection problem we employ a standard matching algorithm with a multi-dimensional distance measure. The effects of the analyzed programmes (wage subsidies, start-up subsidies and qualification measures for recipients of social welfare) are very heterogeneous. It can be observed that the direct integration into the regular labour market provides an advantage for the supported individuals. Its lasting effects, however, strongly depend on the group of persons being supported, the type of treatment and the employers’ financial share.

Progressivity and flexibility in developing an effective competition regime: using experiences of Poland, Ukraine and South Africa for developing countries. Forschungsbericht innerhalb des EU-Projektes: Competition Policy Foundations for Trade Reform, Regulatory Reform, and Sustainable Development, 2005
Franz Kronthaler, Johannes Stephan
One-off Publications,
No. 5,
2005
Abstract
The paper discusses the role of the concept of special and differential treatment in the framework of regional trade agreements for the development of a competition regime. After a discussion of the main characteristics and possible shortfalls of those concepts, three case countries are assessed in terms of their experience with progressivity, flexibility, and technical and financial assistance: Poland was led to align its competition laws to match the model of the EU. The Ukraine opted voluntarily for the European model, this despite its intense integration mainly with Russia. South Africa, a developing country that emerged from a highly segregated social fabric and an economy dominated by large conglomerates with concentrated ownership. All three countries enacted (or comprehensively reformed) their competition laws in an attempt to face the challenges of economic integration and catch up development on the one hand and particular social problems on the other. Hence, their experience may be pivotal for a variety of different developing countries who are in negotiations to include competition issues in regional trade agreements. The results suggest that the design of such competition issues have to reflect country-particularities to achieve an efficient competition regime.

Fiscal economy potentials of a county structure reform in Saxony-Anhalt
Simone Scharfe
Wirtschaft im Wandel,
No. 5,
2006
Abstract
In view of the foreseeable demographic and finance-political developments the public house holds of Eastern Germany are under considerable strain to consolidate. This applies particularly to Saxony-Anhalt and there especially to local authorities. In 2003 the municipal expenses level (running material expenses and personnel expenses) of counties and communities in Saxony-Anhalt amounted 1,015 Euro per inhabitant and was clearly higher than the other East German states. Beyond the means of economisation through the efficient application of public funds, considerations are given to the potentials of country structure reforms. In the last legislative period, the CDU/FDP government already established the amalgamation of 24 counties to eleven new ones with the bill of 11.11.2005. The SPD - as an oppositional party at that time - submitted a proposal for an even further-reaching structural change with a concentration to five counties. This article comprises an estimation of the fiscal economisation potentials of both versions. In the first step, the (long term accessible) county expense levels of Saxony-Anhalt within the scope of the existing structure of a county is determined with the help of a Benchmarkanalysis. These results are then compared with expected expense levels of a reformed county structure which leads to the saving effect of the respective county reform. In the result of the analysis it appears that the suggestion of the SPD to the county structure reform allows to expect clearly higher saving effects than the suggestion of the former CDU/FDP government, a strong meaning of the already enforced community administrative reform is imputable.

Liberalization of Electricity Markets in Selected European Countries
Albrecht Kauffmann, M. Keim, P. J. J. Welfens
Diskussionsbeiträge des Europäischen Instituts für Internationale Wirtschaftsbeziehungen (EIIW), Bergische Universität Wuppertal, Nr. 124,
No. 124,
2004
Abstract
We look into liberalization issues in the context of the EU Electricity Liberalization. Taking a look at principal issues reveals that the Community Directive 96/92/EC does not really take into account the interdependencies of energy markets. Moreover, third party access is not effectively enforced, particularly not in Germany, where mergers between a major electricity company and the dominant gas company have raised particular issues. Electricity liberalization in Scandinavia is working relatively well. EU accession countries are considered potential electricity exporters in the long run as full restructuring will drive down both energy intensities and electricity intensities. Russia would be wise to quickly become a member country of WTO, not in the least to gain access to Western Europe’s electricity market; the role of Russia so far has been neglected in the discussion of electricity liberalization. Excess capacities in EU-27 can be expected in the medium term. There is considerable doubt that politicians – often with ambitious goals in the field of environmental policy – will allow for a pan-European liberalization of electricity. We also take a closer look at regulatory policy issues.

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.
