Abstract
As part of the outsourcing, industrial enterprises receive services in the production of their products which they used to provide on their own. As a result of the wage differentials between industry and service sector there is a shift in the burden labour costs have on industrial products. The study addresses the question of how significant this effect is. For this purpose the open static input-output model is used to analyse the degree of integration of the industry with its suppliers, the employment intensity of production and the labour cost differentials between the areas of production in Germany and in comparison with France and the Netherlands. The result of the labour cost analysis of industrial production shows - from a macroeconomic point of view - that the industry products have a smaller burden due to labour costs in Germany, France and the Netherlands, than the sectoral levels in the industry indicate. The difference in Germany is quantitative particularly strong pronounced. This saving in wage costs has increased somewhat after 2000. Crucial is that this discharge effect is achieved on the immediate wholesale inputs, that means in the first integration stage of industrial production.

Testing for Structural Breaks at Unknown Time: A Steeplechase
Makram El-Shagi, Sebastian Giesen
Abstract
This paper analyzes the role of common data problems when identifying structural breaks in small samples. Most notably, we survey small sample properties of the most commonly applied endogenous break tests developed by Brown, Durbin, and Evans (1975) and Zeileis (2004), Nyblom (1989) and Hansen (1992), and Andrews, Lee, and Ploberger (1996). Power and size properties are derived using Monte Carlo simulations. Results emphasize that mostly the CUSUM type tests are affected by the presence of heteroscedasticity, whereas the individual parameter Nyblom test and AvgLM test are proved to be highly robust. However, each test is significantly affected by leptokurtosis. Contrarily to other tests, where skewness is far more problematic than kurtosis, it has no additional effect for any of the endogenous break tests we analyze. Concerning overall robustness the Nyblom test performs best, while being almost on par to more recently developed tests in terms of power.

The Emergence of Wage Coordination in the Central Western European Metal Sector and its Relationship to European Economic Policy
Vera Glassner, Toralf Pusch
Abstract
In the European Monetary Union the transnational coordination of collective wage bargaining has acquired increased importance on the trade union agenda. The metal sector has been at the forefront of these developments. This paper addresses the issue of crossborder coordination of wage setting in the metal sector in the central western European region, that is, in Germany, the Netherlands and Belgium, where coordination practices have become firmly established in comparison to other sectors. When testing the interaction of wage developments in the metal sector of these three countries, relevant macroeconomic (inflation and labour productivity) and sector-related variables (employment, export-dependence) are considered with reference to the wage policy guidelines of the European Commission and the European Metalworkers’ Federation. Empirical evidence can be found for a wage coordination effect in the form of increasing compliance with the wage policy guidelines of the European Metalworkers’ Federation. The evidence for compliance with the stability-oriented wage guideline of the European Commission is weaker.

International Bank Portfolios: Short- and Long-Run Responses to Macroeconomic Conditions
S. Blank, Claudia M. Buch
Review of International Economics,
No. 2,
2010
Abstract
International bank portfolios constitute a large component of international country portfolios. Yet, banks’ response to international macroeconomic conditions remains largely unexplored.We use a novel dataset on banks’ international portfolios to answer three questions. First, what are the long-run determinants of banks’ international portfolios? Second, how do banks’ international portfolios adjust to short-run macroeconomic developments? Third, does the speed of adjustment change with the degree of financial integration?We find that, in the long-run, market size has a positive impact on foreign assets and liabilities. An increase in the interest differential between the home and the foreign economy lowers foreign assets and increases foreign liabilities. Foreign trade has a positive impact on international bank portfolios, which is independent from the effect of other macroeconomic variables. Short-run dynamics show heterogeneity across countries, but these dynamics can partly be explained with gravity-type variables.

Does Export Openness Increase Firm-level Output Volatility?
Claudia M. Buch, Jörg Döpke, H. Strotmann
World Economy,
No. 4,
2009
Abstract
There is a widespread concern that increased trade may lead to increased instability and thus risk at the firm level. Greater export openness can indeed affect firm-level volatility by changing the exposure and the reaction of firms to macroeconomic developments. The net effect is ambiguous from a theoretical point of view. This paper provides firm-level evidence on the link between openness and volatility. Using comprehensive data on more than 21,000 German manufacturing firms for the period 1980–2001, we analyse the evolution of firm-level output volatility and the link between volatility and export openness. Our paper has three main findings. First, firm-level output volatility is significantly higher than the level of aggregate volatility, but it displays similar patterns. Second, increased export openness lowers firm-level output volatility. This effect is primarily driven by variations along the extensive margin, i.e. by the distinction between exporters and non-exporters. Variations along the intensive margin, i.e. the volume of exports, tend to have a dampening impact on volatility as well. Third, small firms are more volatile than large firms.

Wirtschaft im Wandel,
No. 1,
2009
Abstract
This article deals with the macroeconomic effects of different economic stimulus packages. It evaluates several measures including direct tax cuts, a reduction of the contribution payment to social security, an increase in government spending and a temporary cut of the value added tax rate. Further, the measures of the latest economic stimulus packages are assessed and it is found that their effects on production and employment are only of moderate size.

Growth, Volatility, and Credit Market Imperfections: Evidence from German Firms
Claudia M. Buch, Jörg Döpke
Journal of Economic Studies,
2008
Abstract
Purpose – The purpose of this paper is two-fold. First, it studies whether output volatility and growth are linked at the firm-level, using data for German firms. Second, it explores whether the link between volatility and growth depends on the degree of credit market imperfections.
Design/methodology/approach – The authors use a novel firm-level dataset provided by the Deutsche Bundesbank, the so-called Financial Statements Data Pool. The dataset has time series observations for German firms for the period 1997-2004, and the authors use information on the debt-to-assets or leverage ratio of firms to proxy for credit-constraints at the firm-level. As additional proxies for the importance of credit market imperfections, we use information on the size and on the legal status of firms.
Findings – The authors find that higher volatility has a negative impact on growth for small and a positive impact for larger firms. Higher leverage is associated with higher growth. At the same time, there is heterogeneity in the determinants of growth across firms from different sectors and across firms with a different legal status.
Practical implications – While most traditional macroeconomic models assume that growth and volatility are uncorrelated, a number of microeconomic models suggest that the two may be linked. However, it is unclear whether the link is positive or negative. The paper presents additional evidence regarding this question. Moreover, understanding whether credit market conditions affect the link between volatility and growth is of importance for policy makers since it suggests a channel through which the credit market can have long-run welfare implications. The results stress the importance of firm-level heterogeneity for the effects and effectiveness of economic policy measures.
Originality/value – The paper has two main novel features. First, it uses a novel firm-level dataset to analyze the determinants of firm-level growth. Second, it analyzes the growth-volatility nexus using firm-level data. To the best of the authors' knowledge, this is the first paper, which addresses the link between volatility, growth, and credit market imperfections using firm-level data.

Monetary Policy and Financial (In)stability: An Integrated Micro–Macro Approach
Ferre De Graeve, Thomas Kick, Michael Koetter
Journal of Financial Stability,
No. 3,
2008
Abstract
Evidence on central banks’ twin objective, monetary and financial stability, is scarce. We suggest an integrated micro–macro approach with two core virtues. First, we measure financial stability directly at the bank level as the probability of distress. Second, we integrate a microeconomic hazard model for bank distress and a standard macroeconomic model. The advantage of this approach is to incorporate micro information, to allow for non-linearities and to permit general feedback effects between financial distress and the real economy. We base the analysis on German bank and macro data between 1995 and 2004. Our results confirm the existence of a trade-off between monetary and financial stability. An unexpected tightening of monetary policy increases the probability of distress. This effect disappears when neglecting microeffects and non-linearities, underlining their importance. Distress responses are largest for small cooperative banks, weak distress events, and at times when capitalization is low. An important policy implication is that the separation of financial supervision and monetary policy requires close collaboration among members in the European System of Central Banks and national bank supervisors.

Das makroökonometrische Modell des IWH: Eine angebotsseitige Betrachtung
Rolf Scheufele
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.
