Abstract
The contribution analysis the impact of the average age and experience of employees on the firm’s productivity using the linked employer employee data set from the IAB (LIAB). The inquiry is restricted to the manufacturing sector and distinguishes between a low-tech and a high-tech sector. We find an inverted u-shaped relationship between age and productivity. Experience supports productivity, however, the experience based effects are too small to compensate the negative impact of age at higher stages.

The Long Way to Convergence

Wirtschaft im Wandel,
20 Jahre Deutsche Einheit - Teil 1 -
2009
Abstract
After nearly 20 years of economic development in unified Germany, East German states compared to the West German Leander still lag behind in terms of welfare. During the years immediately following unification, East Germany displayed high economic growth, but lost its relative strength largely in recent times. Therefore, this paper asks whether East Germany is still catching up in terms of per capita output. By considering the cross- section of German states, one can estimate an average convergence speed of approximately 2% per year. However, this catching-up process is partly driven by demographic effects and by migration from East to West Germany. If one considers a time series test of convergence, a catching-up process can still be identified, although the speed is lower and estimated to be around 1%. This implies that the convergence process of East Germany will need further decades until the regional gap will be closed.

Inflation Expectations: Does the Market Beat Professional Forecasts?
Makram El-Shagi
IWH Discussion Papers,
No. 16,
2009
Abstract
The present paper compares expected inflation to (econometric) inflation forecasts
based on a number of forecasting techniques from the literature using a panel of
ten industrialized countries during the period of 1988 to 2007. To capture expected
inflation we develop a recursive filtering algorithm which extracts unexpected inflation from real interest rate data, even in the presence of diverse risks and a potential Mundell-Tobin-effect.
The extracted unexpected inflation is compared to the forecasting errors of ten
econometric forecasts. Beside the standard AR(p) and ARMA(1,1) models, which
are known to perform best on average, we also employ several Phillips curve based approaches, VAR, dynamic factor models and two simple model avering approaches.

A Professor Like Me: The Influence of Instructor Gender on College Achievement
Florian Hoffmann, Philip Oreopoulos
Journal of Human Resources,
No. 2,

Abstract
Many wonder whether teacher gender plays an important role in higher education by influencing student achievement and subject interest. The data used in this paper help identify average effects from male and female college students assigned to male or female teachers. We find instructor gender plays only a minor role in determining college student achievement. Nevertheless, the small effects provide evidence that gender role models matter to some college students. A same-sex instructor increases average grade performance by at most 5 percent of its standard deviation and decreases the likelihood of dropping a class by 1.2 percentage points.

The Euro and the Competitiveness of European Firms

Economic Policy,
No. 57,
2009
Abstract
Much attention has been paid to the impact of a single currency on actual trade volumes. Lower trade costs, however, matter over and beyond their effects on trade flows: as less productive firms are forced out of business by the tougher competitive conditions of international markets, economic integration fosters lower prices and higher average productivity. We assess the quantitative relevance of these effects calibrating a general equilibrium model using country, sector and firm-level empirical observations. The euro turns out to have increased the overall competitiveness of Eurozone firms, and the effects differ along interesting dimensions: they tend to be stronger for countries which are smaller or with better access to foreign markets, and for firms which specialize in sectors where international competition is fiercer and barriers to entry lower.— Gianmarco I.P.

Evidence on the effects of inflation on price dispersion under indexation
Juliane Scharff, S. Schreiber
IMK Working Paper, No. 12/2008,
2008
Abstract
Distortionary effects of inflation on relative prices are the main argument for inflation stabilization in macro models with sticky prices. Under indexation of non-optimized prices those models imply a nonlinear and dynamic impact of inflation on the cross-sectional price dispersion (relative-price variability, RPV). Using US sectoral prices we estimate (a generalized form of) the theoretical relationship between inflation and RPV. We confirm the impact of inflation fluctuations but find hitherto neglected endogeneity biases, and our IV and GMM estimates indicate that average (“trend“) inflation is significant for indexation. Lagged inflation is less important.

Foreign Subsidiaries in the East German Innovation System – Evidence from manufacturing industries
Jutta Günther, Johannes Stephan, Björn Jindra
Applied Economics Quarterly Supplement,
No. 59,
2008
Abstract
This paper analyses the extent of technological capability of foreign subsidiaries located in East Germany, and looks at the determinants of foreign subsidiaries’ technological sourcing behaviour. The theory of international production underlines the importance of strategic and regional level variables. However, existing empirical approaches omit by and large regional level factors. We employ survey evidence from the “FDI micro database” of the IWH, that was only recently made available, to conduct our analyses. We find that foreign subsidiaries are above average technologically active in comparison to the whole East German manufacturing. This can be partially explained by the industrial structure of foreign direct investment. However, only a limited share of foreign subsidiaries with R&D and/or innovation activity source technological knowledge from the East German innovation system. If a subsidiary follows a competence augmenting strategy or does local trade, it is more likely to source technological knowledge locally. The endowment of a region with human capital and a scientific infrastructure has a positive effect too. The findings suggest that foreign subsidiaries in East Germany are only partially linked with the regional innovation system. Policy implications are discussed.

Wie effektiv sind Technologie- und Gründerzentren in den Neuen Bundesländern?
Michael Schwartz
List Forum für Wirtschafts- und Finanzpolitik,
2008
Abstract
In Eastern Germany, since the beginning of the 1990s technology centers and business incubators are established by cities and municipalities to provide a favorable business environment for young and newly founded innovative firms. Right from the beginning, the effectiveness of these support facilities has been the subject of intense academic and policy discussions, but empirical evidence on the actual effectiveness of these centers is limited so far. Taking into account that the choice of the appropriate criteria for evaluations of the effectiveness of technology centers and business incubators is far from clear cut, this article focuses on three core indicators that are generally accepted as measures for effectiveness (incubation time, share of newly founded firms in the tenant portfolio and technological level of the supported firms), and analyses for five business incubators in East Germany whether they can be characterized as being effective policy instruments. A positive assessment of the five incubators’ effectiveness can be made with regard to average incubation time of tenant companies, as well as insofar the share of newly founded firms on all supported companies is concerned. However, deficiencies are found regarding the technological level of the incubator firms.

East German Innovation System attractive for Foreign Investors
Jutta Günther, Björn Jindra, Johannes Stephan
Wirtschaft im Wandel,
No. 1,
2008
Abstract
Foreign direct investment (FDI) plays an important role in the catching-up process of East Germany due to direct employment- and demand related effects. However, this article takes a technological perspective on FDI in East Germany. It considers technological activities of foreign investors (R&D and innovation) and asks to what extent these are integrated into the East German innovation system. In other words, do foreign investors interact technologically with domestic enterprises and scientific institutions? So far, there seems to be a striking absence of empirical evidence on this issue. The basis for our analysis is recent data from a representative survey of foreign direct investors in East German manufacturing completed in 2007. The findings show that on average foreign investors are more R&D and innovation intensive compared to the total of East German manufacturing. In addition, their technological activities are by no means isolated from the East German innovation system. Foreign subsidiaries seem to benefit from East German customers, suppliers and especially scientific institutions with regard to locally conducted R&D and innovation. Contrary to existing assumptions the East German innovation system seems to be particularly attractive for the most technologically active foreign subsidiaries. This could constitute a major locational advantage for FDI in East Germany over Central and East Europe. However, the technologically active foreign investors believe that only East German suppliers are able to benefit from their technological cooperation. The same cannot be said about East German customers or competitors. Thus, the potential for technological externalities from FDI in East Germany seems still to be limited.
