Abstract
In this paper we analyze the small sample properties of full information and limited information estimators in a potentially misspecified DSGE model. Therefore, we conduct a simulation study based on a standard New Keynesian model including price and wage rigidities. We then study the effects of omitted variable problems on the structural parameter estimates of the model. We find that FIML performs superior when the model is correctly specified. In cases where some of the model characteristics are omitted, the performance of FIML is highly unreliable, whereas GMM estimates remain approximately unbiased and significance tests are mostly reliable.

Women Move Differently: Job Separations and Gender
Boris Hirsch, Claus Schnabel
Journal of Labor Research,
No. 4,
2012
Abstract
Using a large German linked employer–employee data set and methods of competing risks analysis, this paper investigates gender differences in job separation rates to employment and nonemployment. In line with descriptive evidence, we find lower job-to-job and higher job-to-nonemployment transition probabilities for women than men when controlling for individual and workplace characteristics and unobserved plant heterogeneity. These differences vanish once we allow these characteristics to affect separations differently by gender. When additionally controlling for wages, we find that both separation rates are considerably lower and also significantly less wage-elastic for women than for men, suggesting an interplay of gender differences in transition behaviour and the gender pay gap.

Finance and Growth in a Bank-Based Economy: Is It Quantity or Quality that Matters?
Michael Koetter, Michael Wedow
Journal of International Money and Finance,
No. 8,
2010
Abstract
Most finance–growth studies approximate the size of financial systems rather than the quality of intermediation to explain economic growth differentials. Furthermore, the neglect of systematic differences in cross-country studies could drive the result that finance matters. We suggest a measure of bank’s intermediation quality using bank-specific efficiency estimates and focus on the regions of one economy only: Germany. This quality measure has a significantly positive effect on growth. This result is robust to the exclusion of banks operating in multiple regions, controlling for the proximity of financial markets, when distinguishing different banking sectors active in Germany, and when excluding the structurally weaker East from the sample.

The Impact of Psychic Distance on Subsidiary Autonomy - Theory and Evidence from Central and Eastern European Countries
Gjalt de Jong, D. van Vo, Philipp Marek
Journal of International Management,
2012
Abstract
The key objective of this study is to determine whether or not psychic distance between home and host countries influences the decision-making autonomy of subsidiaries. Theoretical arguments for the relationship between psychic distance and subsidiary autonomy go in both directions with some predicting a negative relationship and others predicting a positive one. We test these conflicting hypotheses with a unique multi-country and multi-industry database reporting survey evidence of 809 subsidiaries located in five Central and Eastern European countries that serve headquarters in 44 different nation states. Psychic distance is a multidimensional construct and measured in terms of linguistic, religious, economic, institutional and geographic distance. The empirical results of 103 country pairs suggest that psychic distance – in terms of religious and economic distance – is positively related to autonomy.

Size, Productivity, and International Banking
Claudia M. Buch, C. T. Koch, Michael Koetter
Journal of International Economics,
No. 2,
2011
Abstract
Heterogeneity in size and productivity is central to models that explain which manufacturing firms export. This study presents descriptive evidence on similar heterogeneity among international banks as financial services providers. A novel and detailed bank-level data set reveals the volume and mode of international activities for all German banks. Only a few, large banks have a commercial presence abroad, consistent with the size pecking order documented for manufacturing firms. However, the relationship between internationalization and productivity also yields two inconsistencies with recent trade models. First, virtually all banks hold at least some foreign assets, irrespective of size or productivity. Second, some fairly unproductive banks maintain commercial presences abroad.

Flow of Conjunctural Information and Forecast of Euro Area Economic Activity
Katja Drechsel, L. Maurin
Journal of Forecasting,
No. 3,
2011
Abstract
Combining forecasts, we analyse the role of information flow in computing short-term forecasts up to one quarter ahead for the euro area GDP and its main components. A dataset of 114 monthly indicators is set up and simple bridge equations are estimated. The individual forecasts are then pooled, using different weighting schemes. To take into consideration the release calendar of each indicator, six forecasts are compiled successively during the quarter. We found that the sequencing of information determines the weight allocated to each block of indicators, especially when the first month of hard data becomes available. This conclusion extends the findings of the recent literature. Moreover, when combining forecasts, two weighting schemes are found to outperform the equal weighting scheme in almost all cases. Compared to an AR forecast, these improve by more than 40% the forecast performance for GDP in the current and next quarter.

IT Use, Productivity, and Market Power in Banking
Michael Koetter, Felix Noth
Journal of Financial Stability,
No. 4,
2013
Abstract
Information management is a core process in banking that can resolve information asymmetries and thereby help to mitigate competitive pressure. We test if the use of information technology (IT) contributes to bank output, and how IT-augmented bank productivity relates to differences in market power. Detailed bank-level information on the use of IT reveals a substantial upward bias in bank productivity estimates when ignoring banks’ IT expenditures. IT-augmented bank productivity correlates positively with Lerner markups. A mere increase in IT expenditures, however, reduces markups. Results hold across a range of bank output definitions and productivity estimation methods.

Expansion Continues to Be Strong

No. 10,

Abstract
The business cycle upswing in Germany has gained strength and breadth. In addition to private consumption, the expansion is now also supported by investment and foreign trade. The latter benefits from growing exports to the euro area, where the economy is gaining momentum. Since the euro area upswing rests on solid fundamentals, the ECB should be able to start tapering without putting the economy at risk.

How Can We Boost Competition in the Services Sector?

Externer Herausgeberband, Nomos,
2017
Abstract
‘How Can We Boost Competition in the Services Sector?’ is a key question in the process of creating a more effi-cient economic environment in Germany. This book contains a collection of conference contributions on service sector reforms from members of academic institutions, ministries, the EU Commission and other organisations. The conference consisted of a keynote on the importance and implementation of structural reforms in Europe and two panels that dealt with the evaluation of past reforms in the services sector and the potential scope and effects of further reforms. Since the 1990s, productivity growth in Germany and other Member States of the European Union has been significantly lower than in the US. The development of productivity growth in the services sector is estimated to account for two thirds of this widening gap. The European Commission advocated reforms in the services sector in its country-specific recommendations for Germany. At a conference in Berlin in July 2016, experts from various fields presented and discussed studies on service sector reforms.

Corporate Taxation and Firm Location in Germany
Götz Zeddies
IWH Discussion Papers,
No. 2,
2015
Abstract
German Fiscal Federalism is characterized by a high degree of fiscal equalization which lowers the efficiency of local tax administration. Currently, a reform of the fiscal equalization scheme is on the political agenda. One option is to grant federal states the right to raise surtaxes on statutory tax rates set by the central government in order to reduce the equalization rate. In such an environment, especially those federal states with lower economic performance would have to raise comparatively high surtaxes. With capital mobility, this could further lower economic performance and thus tax revenues. Although statutory tax rates are so far identical across German federal states, corporate tax burden differs for several reasons. This paper tries to identify the impact of such differences on firm location. As can be shown, effective corporate taxation did seemingly not have a significant impact on firm location across German federal states.
