Abstract
20 Jahre nach der „friedlichen Revolution“ und dem darauffolgenden Herstellen der staatlichen Einheit Deutschlands legt das IWH erneut eine Dokumentation der gesellschaftlichen, vor allen Dingen der wirtschaftlichen Entwicklung vor. Ziel ist es, anhand von Zahlen, Schaubildern und Tabellen mit entsprechenden Erklärungen die Vielschichtigkeit des Wandels der Neuen Länder aufzuzeigen. Damit fällt auch die Bewertung differenziert aus: Es gibt eine weitgehend modernisierte Infrastruktur, das erste, was an „blühende Landschaften“ erinnern mag. Einige Unternehmen und Standorte konnten sich mit großem wirtschaftlichen Erfolg die Weltmarktführerschaft in wesentlichen Technologien sichern. Aber es gibt auch einen massiven Bevölkerungsverlust, sich entleerende Gebiete. Manche Städte und erhebliche Teile des ländlichen Raums suchen eine neue Aufgabe in der nationalen und internationalen Arbeitsteilung.

Great Moderation at the Firm Level? Unconditional vs. Conditional Output Volatility

B.E. Journal of Economic Analysis and Policy,
No. 1,
2009
Abstract
We test whether there has been a “Great Moderation“ of output volatility at the firm level. The multifactor residual model proposed by Pesaran (2006) is used to isolate the idiosyncratic component of firms' sales growth from macroeconomic developments. This methodology is applied to a balanced panel of about 1,200 German firms covering a 35-year period (1971-2005). Our research has three main findings. First, unconditional firm-level volatility and aggregate output volatility have seen similar downward trends. Second, conditional, idiosyncratic firm-level volatility does not exhibit a downward trend. Third, there is a positive link between growth and volatility at the firm level.

Does Export Openness Increase Firm-level Output Volatility?

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.

Economic Stimulus Packages and their Effects – A Simulation with the IWH Macroeconometric Model
Rolf Scheufele
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.

Development of Economy and Public Budgets in the Medium Term
Kristina vanDeuverden, Rolf Scheufele
Wirtschaft im Wandel,
No. 1,
2009
Abstract
The paper presents a forecast of the medium term development in Germany. In the years 2010 until 2013, economic growth will come on average to 1½%, basically borne by foreign trade as well as domestic demand. Public budgets will worsen in the years 2009 until 2010 mainly due to the present downturn and the political measures taken in this context. During the years afterwards, public finances will start to recover slightly.

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.

The Great Risk Shift? Income Volatility in an International Perspective
Claudia M. Buch
CESifo Working Paper No. 2465,
2008
Abstract
Weakening bargaining power of unions and the increasing integration of the world economy may affect the volatility of capital and labor incomes. This paper documents and explains changes in income volatility. Using a theoretical framework which builds distribution risk into a real business cycle model, hypotheses on the determinants of the relative volatility of capital and labor are derived. The model is tested using industry-level data. The data cover 11 industrialized countries, 22 manufacturing and services industries, and a maximum of 35 years. The paper has four main findings. First, the unconditional volatility of labor and capital incomes has declined, reflecting the decline in macroeconomic volatility. Second, the idiosyncratic component of income volatility has hardly changed over time. Third, crosssectional heterogeneity in the evolution of relative income volatilities is substantial. If anything, the labor incomes of high- and low-skilled workers have become more volatile in relative terms. Fourth, income volatility is related to variables measuring the bargaining power of workers. Trade openness has no significant impact.
