Abstract
Changes in production and employment are closely related over the course of the business cycle. However, as exemplified by the laws of Verdoorn (1949, 1993) and Okun (1962, 1970), thresholds seem to be present in the relationship. Due to capacity reserves of the firms, output growth must exceed certain levels for the creation of new jobs or a fall in the unemployment rate. While Verdoorn's law focuses on the growth rate of output sufficient for an increase in employment, in Okun's law, the fall in the unemployment rate becomes the focus of attention. In order to assess the future development of employment and unemployment, these thresholds have to be taken into account. They serve as important guidelines for policymakers. In contrast to previous studies, we present joint estimates for both the employment and unemployment threshold. Due to demographic patterns and institutional settings on the labour market, the two thresholds can differ, implying that minimum output growth needed for a rise in employment may not be sufficient for a simultaneous drop in the unemployment rate. Second, regional information is considered to a large extent. In particular, the analysis is carried out using a sample of 180 German regional labour markets, see Eckey (2001). Since the cross-sections are separated by the flows of job commuters, they correspond to travel-to-work areas. Labour mobility is high within a market, but low among the entities. As the sectoral decomposition of economic activities varies across the regions, the thresholds are founded on a heterogeneous experience, leading to more reliable estimates.The contribution to the literature is twofold. First, to the best of our knowledge, no previous paper has investigated a similar broad regional dataset for the German economy as a whole before. By using a panel dataset, information on the regional distributions around the regression lines as well as theirs positional changes is provided for each year. Second, the methods applied are of new type. They involve a mixture of pooled and spatial econometric techniques. Dependencies across the regions may result from common or idiosyncratic (region specific) shocks. In particular, the eigenfunction decomposition approach suggested by Griffith (1996, 2000) is used to identify spatial and non-spatial components in regression analysis. As the spatial pattern may vary over time, inference is conducted on the base of a spatial SUR model. Due to this setting, efficient estimates of the thresholds are obtained. With the aid of a geographic information system (GIS) variation of the spatial components can be made transparent. With Verdoorn’s and Okun’s law the figures show some significant patterns become obvious over time. In respect to Verdoorn’s law, for instance, a stripe of high values in the north-western part from Schleswig-Holstein via Lower Saxony and North Rhine Westfalia to Rhineland Palatinate is striking in all years but 1994 and 1995. In most periods the spatial component is likewise concentrated in Saxony. Clusters of low values can be found in northern Bavaria and, in some periods, in Thüringen and Mecklenburg-Vorpommern. Other parts of Germany appear to be more fragmented consisting of relative small clusters of low, medium and high values of the spatial component. With Okun’s law some changing spatial patterns arise. In all, spatially filtering provides valuable insights into the spatial dimensions of the laws of Verdoorn and Okun.

Institutional settings of social assistance: What is improved or unsolved by the
Joachim Wilde
Institutionen und Arbeitsmarkt: Messkonzepte, Wirkungszusammenhänge und internationaler Vergleich,
2006
Abstract
The last reform of benefits for long-term unemployed in Germany ("Hartz IV") did not reduce costs. Moreover, the number of recipients is much higher than it was expected before. Therefore, the institutional settings might be less effective than they could be. Initially, the paper describes the institutional changes by the "Hartz IV" reform. Afterwards, these changes are evaluated with respect to their effects on the number of recipients. The evaluation is based on the results of econometric studies concerning the former social assistance. It is pointed out that the reform improved basic conditions and incentives only partly, whereas some of its elements worsened the institutional settings.

Optimierung der Geldpolitik in Schwellenländern durch einen International-Lender-of-Last-Resort

Europäische Hochschulschriften, Reihe 5 Volks- und Betriebswirtschaft, Band 3202,
2006
Abstract
Current currency crises in emerging market economies show the insufficiency of preventive measures on national, regional and international level. The task of the book is therefore to analyze systematically which conditions monetary policy has to fulfill in order to prevent currency crises. In a first step optimal, crises-preventing monetary policy is modeled. Further the chances for overcoming the limitations of national policy are discussed on the regional and international level. The main result of the descriptive, theoretical and econometric analysis is the construction of an instrument for international monetary policy: the International Lender of Last Resort.

Hartz IV: not enough learned from welfare
Joachim Wilde
Wirtschaft im Wandel,
No. 2,
2006
Abstract
The so-called “Hartz IV reform“ should improve the system of services and benefits for the long-term unemployed in Germany. Thus, it was expected that the number of recipients and the volume of expenditures will decrease. However, both are higher than before. Therefore, the institutional settings might be less effective than they could be. Initially, the paper describes the institutional changes by the “Hartz IV“ reform. Afterwards, these changes are evaluated with respect to their effects on the number of recipients. The evaluation is based on the results of econometric studies concerning the former social assistance. It is pointed out that the reform improved basic conditions and incentives only partly, whereas some of its elements worsened the institutional settings.

Technology Transfer via Foreign Direct Investment in Central and Eastern Europe: Theory, Method of Research and Empirical Evidence
Johannes Stephan
Technology Transfer via Foreign Direct Investment in Central and Eastern Europe: Theory, Method of Research and Empirical Evidence,
2005
Abstract
Foreign subsidiaries of multinational companies are suggested as one of the main channels of technology transfer to less developed economies. In Central East Europe their presence proved to be a decisive factor to economic restructuring and development. This volume is a unique guide to theory, method of research, and empirical evidence, for technology transfer via foreign subsidiaries of multinational companies. It combines the merits of a core text on technology transfer via FDI with up-to-date empirical evidence.

Technology spillovers from external investors in East Germany: no overall effects in favor of domestic firms
Harald Lehmann, Jutta Günther
IWH Discussion Papers,
No. 198,
2004
Abstract
The study deals with the question whether external (foreign and West German) investors in East Germany induce technological spillover effects in favor of domestic firms. It ties in with a number of other econometric spillover studies, especially for transition economies, which show rather mixed and inconclusive results so far. Different from existing spillover analyses, this study allows for a much deeper regional breakdown up to Raumordnungsregionen and uses a branch classification that explicitly considers intermediate and investment good linkages. The regression results show no positive correlation between the presence of external investors and domestic firms’ productivity, no matter which regional breakdown is looked at (East Germany as a whole, federal states, or Raumordnungsregionen). Technology spillovers which may exist in particular cases are obviously not strong enough to increase the domestic firms’ overall productivity.

A Monetary Vector Error Correction Model of the Euro Area and Implications for Monetary Policy
Oliver Holtemöller
Empirical Economics,
No. 3,
2004
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.

Diversifikation und regionale Wirtschafts- und Beschäftigungsentwicklung - Eine empirische Analyse für ausgewählte deutsche Gebiete
Peter Haug
Jahrbuch für Regionalwissenschaft,
No. 2,
2004
Abstract
This article analyses the effects of heterogeneous economic structures on the long-term development of regional employment. A simple model is introduced to illustrate the beneficial outcomes for households as well as for enterprises of locating in highly diversified municipalities because risk (volatility of income, recruitment costs in a broader sense) diminishes for both. Econometric results for a sample of municipalities in Lower Saxony provide some evidence for a positive effect of local economic diversification on employment opportunities. The results seem to be not confined to the aggregated local labour demand but also apply to most branches the local business sector.

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.
