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.

The Exchange Rate of the Euro Cannot be Explained Fundamentally even Ten Years after the Introduction of the New Currency
Tobias Knedlik
Wirtschaft im Wandel,
No. 1,
2009
Abstract
On first of January 2009, the Euro’s tenth birthday can be celebrated. The introduction of the Euro led to diminishing importance of trade in foreign currency for the Euro-countries. However, a significant part of foreign trade of Germany and other Euro-members is still nominated in foreign currency. Therefore, the external value of the Euro plays a crucial role for the European economy. Since the early depreciation of the exchange rate just after the introduction until 2000, an almost steady increase in the external value of the Euro could be observed. The contribution elaborates on the exchange rate development and tests whether the Euro was following a path as it would be predicted by both, the interest rate parity theory and the purchasing parity theory. Both theoretical approaches are not able to explain the specific valuation figure of the Euro. For the conduct of economic forecasts, it is to conclude that modelling exchange rate developments as random processes can be legitimate. Regarding exchange rate policy, it remains to ask which alternative policy approaches might be better suitable for the European economy.

A Lesson Learned? Pre- and Post-Crisis Entry Decisions in Turkish Banking
H. Evren Damar
Contemporary Economic Policy,
No. 1,
2009
Abstract
This study looks at the determinants of entry by Turkish banks into local markets during the periods before and after the crisis of 2000–2001. Motivated by a theoretical model of entry, results of fixed-effects logit regressions suggest that there has been a change in the geographical diversification strategies of Turkish banks. It appears that the dominance of strategic concerns, such as competing with banks of similar size, has diminished, while economic concerns, such as incumbent characteristics and cost considerations, have become more important. Overall, the postcrisis restructuring policies seem to have led to improved decision making in the sector.

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.

Are European Equity Style Indices Efficient? – An Empirical Quest in Three Essays
Marian Berneburg
Schriften des IWH,
No. 28,
2008
Abstract
Many situations in the history of the stock markets indicate that assets are not always efficiently priced. But why does it matter whether the stock market is efficiently priced? Because “well-functioning financial markets are a key factor to high economic growth”. (Mishkin and Eakins, 2006, pp. 3-4) In three essays, it is the aim of the author to shed some more light on the topic of market efficiency, which is far from being resolved. Since European equity markets have increased in importance globally, the author, instead of focusing on US markets, looks at a unified European equity market. By testing for a random walk in equity prices, revisiting Shiller’s claim of excess volatility through the means of a vector error correction model, and modifying the Gordon-Growth-Model, the book concludes that a small degree of inefficiency cannot be ruled out. While usually European equity markets are pricing assets correctly, some periods (e.g. the late 1990s and early 2000s) show clear signs of mispricing; the hypothesis of a world with two states (regime one, a normal efficient state, and regime two, a state in which markets are more momentum driven) presents a possible explanation.

Exchange Rates and FDI: Goods versus Capital Market Frictions
Claudia M. Buch, J. Kleinert
World Economy,
forthcoming
Abstract
Changes in exchange rates affect countries through their impact on cross-border activities such as trade and foreign direct investment (FDI). With increasing activities of multinational firms, the FDI channel is likely to gain in importance. Economic theory provides two main explanations why changes in exchange rates can affect FDI. According to the first explanation, FDI reacts to exchange rate changes if there are information frictions on capital markets and if investment depends on firms’ net worth (capital market friction hypothesis). According to the second explanation, FDI reacts to exchange rate changes if output and factor markets are segmented, and if firm-specific assets are important (goods market friction hypothesis). We provide a unified theoretical framework of these two explanations. We analyse the implications of the model empirically using a dataset based on detailed German firm-level data. We find greater support for the goods market than for the capital market friction hypothesis.

Evaluating the German (New Keynesian) Phillips Curve
Rolf Scheufele
IWH Discussion Papers,
No. 10,
2008
Abstract
This paper evaluates the New Keynesian Phillips Curve (NKPC) and its hybrid
variant within a limited information framework for Germany. The main interest rests on the average frequency of price re-optimization of firms. We use the labor income share as the driving variable and consider a source of real rigidity by allowing for a fixed firm-specific capital stock. A GMM estimation strategy is employed as well as an identification robust method that is based upon the Anderson-Rubin statistic. We find out that the German Phillips Curve is purely forward looking. Moreover, our point estimates are consistent with the view that firms re-optimize prices every two to three quarters. While these estimates seem plausible from an economic point of view, the uncertainties around these estimates are very large and also consistent with perfect nominal price rigidity where firms never re-optimize prices. This analysis also offers some explanations why previous results for the German NKPC based on GMM differ considerably. First, standard GMM results are very sensitive to the way how orthogonality conditions are formulated. Additionally, model misspecifications may be left undetected by conventional J tests. Taken together, this analysis points out
the need for identification robust methods to get reliable estimates for the NKPC.

On the Rationale of Leniency Programs: a Game-Theoretical Analysis
Ulrich Blum, Nicole Steinat, Michael A. Veltins
European Journal of Law and Economics,
2008
Abstract
In order to enhance the enforcement of Antitrust Law, leniency policies were introduced in nearly all industrialized countries. These programs aim at deterring and eliminating cartels. In this paper we analyze the rationale of the current European and German leniency regulation. We challenge the contemporary view that the standard leniency privilege is incentive-compatible with respect to its aim to enhance competition. Instead, we argue for it to be used as a preemptive strike against competitors under circumstances where cartels become unstable. This implies a tightening of markets in subsequent periods and, thus, a potential reduction in competition intensity. Given strategic reasoning by agents, the principal witness may assure an economically privileged position in the future. This consequence might not be intended by the bonus regulations. Nevertheless if the leniency policies lead to more competition in the market the results should be welcomed by the national cartel offices. We give anecdotal evidence of the German cement case and base our arguments on a game-theoretical model.

The Role of the Human Capital and Managerial Skills in Explaining the Productivity Gaps between East and West
Johannes Stephan, Wolfgang Steffen
Eastern European Economics,
No. 6,
2008
Abstract
This paper assess determinants of productivity gaps between firms in the European transition countries and regions and firms in West Germany. The analysis is conducted at the firm level by use of a unique database constructed by field work. The determinants tested in a simple econometric regression model are focussed upon the issue of human capital and modern market-oriented management. The results are novel in as much as a solution was established for the puzzling results in related research with respect to a comparison of formal qualification between East and West. Furthermore, the analysis was able to establish that the kind of human capital and expertise mostly needed in the post-socialist firms are related to the particular requirements of a competitive market-based economic environment. Finally, the analysis also finds empirical support for the role of capital deepening in productivity catch-up, as well as the case that the gaps in labour productivity are most importantly rooted in a more labour-intense production, which does not give rise to a competitive disadvantage.

Culture as a Base for Efficient Economic Systems
Ulrich Blum
Wirtschaft im Wandel,
No. 2,
2008
Abstract
Globalization puts the German economic model, the so-called social market economy, under pressure. Constituting elements of this model are fundamental social and economic values. Globalization puts some of these values under pressure and creates inefficiencies because the costs of running the social and economic fabric rise. This is an important justification to inquire into the normative foundations of economic efficiency The following article discusses to what extent culture is a base for efficient economic systems. Information theory is regarded as a key element for explaining social change. The arguments are based on institutional economics with a special view on transaction costs and on cooperation structures. It is shown that specific information technologies promote forms of cooperation, which influence institutional arrangements. The related information technologies themselves are part of the cultural system and its value structures. As a consequence, competition among economic systems favours certain combinations of technologies, cultural arrangements and economic systems. In as much as cultural competition precedes economic competition in the sense of a certain way of thinking, the cultural system can be regarded as a strategic competitive parameter for an economy.
